Description

FIELD OF THE DISCLOSURE

The present invention relates to the field of feeding systems, and more particularly to methods and apparatuses for safely and efficiently feeding individuals, including infants, young children, and physically inhibited adults. The invention specifically involves a versatile and adaptable feeding system comprising a graduated connector with multiple connector steps on one or both sides, allowing for the secure attachment of various sizes and types of food containers (and feeding devices). The invention also encompasses features such as one-way valves to control food flow direction, and telescopic and modular designs for compact storage and customization of feeding apparatuses.

BACKGROUND OF THE DISCLOSURE

In modern parenting and caregiving, feeding young children and physically inhibited adults presents a range of challenges, particularly when meals need to be administered outside the home. The evolution of family dynamics and the increased mobility of modern lifestyles have created a demand for practical, hygienic, and portable feeding solutions.

Current feeding methods typically involve multiple components such as spoons, bowls, and separate food containers. These traditional tools, while functional within the controlled environment of a home, often become impractical when used in public or mobile settings. Assembling and managing these components can be cumbersome and increases the likelihood of spills and contamination, complicating the feeding process and compromising hygiene.

The market has seen the introduction of ready-to-use food pouches designed to offer convenience by providing pre-packaged servings of viscous foods. These pouches are available in various sizes to cater to different age groups and dietary needs, from small, single-serving packs suitable for infants to larger containers designed for older children and adults. However, these pouches present significant limitations in terms of usability and hygiene.

Food pouches come with a variety of mouth sizes and shapes. Some have narrow spouts, while others feature wider openings. This lack of standardization makes it challenging to find compatible feeding tools that can effectively interface with different pouches. Users often need to squeeze the food out of the pouch onto a separate spoon or directly into the mouth, which can be messy and unhygienic. This process increases the risk of contamination and can make the feeding experience less satisfactory.

The drawbacks of these methods are particularly pronounced for young children who are transitioning from formula or breast milk to viscous foods. Ensuring that these foods are stored, carried, and dispensed in a hygienic manner is crucial for their health and development. Current solutions often fail to maintain the necessary level of cleanliness, especially in mobile settings where assembling and using separate feeding components can be difficult.

Physically inhibited adults, who rely on caregivers for feeding, also face significant challenges with existing feeding methods. Caregivers often need to manage multiple tools, which can be difficult to handle and maintain hygienically, especially in public or less controlled environments. The lack of integrated solutions that combine storage, transportation, and dispensing of food in a hygienic manner complicates the feeding process and increases the risk of contamination.

The variability in the design and size of food pouches further exacerbates these issues. Parents and caregivers frequently need to switch between different feeding tools and adapters to accommodate various pouch designs, which adds to the logistical burden and frustration. The absence of a universal feeding apparatus that can adapt to different pouch sizes and shapes underscores the inefficiency and impracticality of current methods.

In addition to the challenges posed by the variability of food pouches, the physical characteristics of the individuals being fed must be considered. Infants and young children require feeding devices (e.g., spoons) that are small and gentle, ensuring that the food is dispensed in manageable quantities. In contrast, older children and adults may need larger feeding devices that can handle greater volumes of food. Conventional feeding methods often fail to provide adaptable solutions that cater to these diverse needs effectively.

Furthermore, the focus on reusability and sustainability is another area where traditional feeding methods fall short. Disposable feeding tools contribute to environmental waste and impose additional costs on users. There is a clear need for feeding apparatuses that emphasize reusability and easy cleaning, thereby promoting a more sustainable approach to feeding while also being cost-effective for parents and caregivers.

User-friendliness is another crucial aspect that is often overlooked in the design of traditional feeding methods. Parents and caregivers frequently need to feed children or physically inhibited adults in challenging environments, such as during travel or in public places. Feeding tools that are easy to assemble, use, and clean can significantly reduce the stress associated with feeding in these settings. Traditional methods, with their multiple separate components and lack of intuitive design features, do not adequately address this need.

The conventional approach to feeding, involving separate spoons, bowls, and food containers, fails to integrate these components into a cohesive, practical system. This lack of integration complicates the feeding process, increases the risk of spills and contamination, and fails to meet the hygiene standards necessary for young children and physically inhibited adults. The need for a more streamlined, adaptable, and hygienic solution is evident, highlighting the limitations and inefficiencies of existing feeding methods and apparatuses.

The issues associated with traditional feeding tools emphasize the necessity for innovation in this area. Current methods do not adequately address the needs of modern families who require convenient, portable, and hygienic feeding solutions that can be used effectively both at home and on the go. The diversity in food pouch designs and the varying needs of the individuals being fed further complicate the situation, underscoring the urgent need for a comprehensive and adaptable feeding apparatus that can overcome these significant drawbacks and inefficiencies.

SUMMARY OF THE DISCLOSURE

Accordingly, the present disclosure provides methods and apparatus for feeding a person incapable of feeding themselves, the method including the steps of connecting a food pouch or other food container containing viscous food in an interior of the food container to a spoon or other receiving devices suitable for feeding. The present invention provides a feeding device that may include a feeding portion including a feeding surface. A compressive force may be applied to an exterior surface of the food pouch (or other food-containing receptacle) to expel an amount of the viscous food out of the food pouch onto the feeding surface.

In some embodiments of the present invention, an apparatus is provided for feeding a person viscous food, which includes a feeding device (e.g., a spoon), a food container or pouch, and a graduated or stepped connector. The feeding device is designed with a feeding surface configured to deliver the viscous food directly to the person, offering a secure and comfortable feeding experience. The food container is specifically configured to store the viscous food within a designated food storage portion and includes a food container end connector located at an open end of the storage portion.

The graduated connector comprises a first side and a second side. The first side of the graduated connector includes a first set of connector steps, each with a distinct size, designed to accommodate varying sizes of food container end connectors. This design allows the food container to be securely attached to the graduated connector, allowing for a smooth flow of viscous food from the container to the feeding device.

In some embodiments, the food container end connector is designed to be removably attachable to a selected connector step on the first side of the graduated connector. This attachment mechanism may involve threaded engagements, where both the food container end connector and the selected connector step are threaded to securely interlock with each other. Alternatively, the attachment may utilize a snap-fit mechanism, wherein the food container end connector snaps into place within the selected connector step. In this snap-fit configuration, the graduated connector may be constructed from a flexible material that can expand slightly upwards during the attachment process, providing a secure and leak-proof fit (i.e., the flexible material contracts when the food container end connector is inserted, providing a force downwards).

The graduated connector itself may be designed to include multiple connector steps on the first side, each capable of engaging a different size of food container end connector. This allows the apparatus to accommodate a wide range of food containers, providing versatility in feeding scenarios. Additionally, the feeding device may also be removably attached to the second side of the graduated connector, further enhancing the system's flexibility.

In some embodiments, the feeding device may include a feeding device end connector, which can be removably attached to the second side of the graduated connector. The graduated connector may also feature a second set of connector steps on the second side, each with a distinct size to accommodate varying sizes of feeding device end connectors. This design allows the feeding system to be highly adaptable, with the potential for telescopic functionality where the connector steps on one or both the first side and second side can retract, or modular construction where connector steps can be replaced or added as needed.

The apparatus may further include a plurality of feeding devices, each with a feeding surface of a distinct size, catering to different feeding needs. Additionally, the system may incorporate a plurality of food containers, each equipped with a fixedly attached food container end connector of distinct size. These food containers can be designed to store different types of viscous food, allowing for easy interchangeability depending on the specific feeding requirements.

In some embodiments of the present invention, a method for feeding a person viscous food is provided, which begins by selecting an appropriate feeding device equipped with a feeding surface specifically designed to deliver viscous food to the person. The feeding surface may vary in size and shape depending on the user's needs, such as infants, children, or adults, providing a comfortable and efficient feeding process. The feeding device may include a feeding device end connector that is fixedly attached to the feeding device and configured to be removably attached to the second side of a graduated connector.

Next, the method involves selecting a food container designed to store the viscous food. The food container includes a food storage portion, and a food container end connector fixedly attached to an open end of the storage portion. The food container end connector may be of varying sizes and may feature a threaded design or a snap-fit mechanism, enabling secure and reliable attachment to the graduated connector. The choice between threaded or snap-fit mechanisms allows for flexibility depending on the specific requirements of the feeding scenario, with the snap-fit option being particularly beneficial for single-handed operation.

The graduated connector may include a first side equipped with a plurality of connector steps, each of which has a distinct size to accommodate different sizes of food container end connectors. A second side of the graduated connector is attached to the feeding device, either permanently or through a removable connection (i.e., the second side also comprises a plurality of connector steps). This design allows the feeding system to adapt to various food containers and feeding devices, making it versatile for different users and types of viscous food.

The caregiver may select a connector step on the first side of the graduated connector that is appropriately sized to securely fit the food container end connector. Once the correct step is selected, the food container end connector is attached to this step, either by threading or snapping it into place, depending on the connector step design. The secure attachment of the food container to the graduated connector is useful for preventing leaks and providing a steady flow of viscous food during feeding.

The method also allows for the selection and use of a plurality of feeding devices, each with a feeding surface of distinct size, to cater to different feeding needs. Similarly, the method may involve selecting from a plurality of food containers, each configured to store different types of viscous food and equipped with a fixedly attached food container end connector of a distinct size. The plurality of containers allows the feeding system to be easily adapted to different types of food, from purees to thicker substances, without compromising the ease of use or safety.

When a larger food container end connector is attached to a larger connector step on the first side of the graduated connector, the method includes enabling the viscous food to flow through one or more food-flow paths formed between the larger connector step and smaller connector steps within the graduated connector. This food flow path configuration allows that the viscous food can move efficiently from the food container, through the graduated connector, and onto the feeding surface of the feeding device, even when multiple connector steps are involved (i.e., multiple connector steps are enclosed within the larger food container end connector attached to the larger connector step).

The modular design of the graduated connector allows for the plurality of connector steps on one or both of the first side and the second side to be replaced or added as needed. This modularity provides significant flexibility, allowing the user to customize the feeding system to accommodate new food containers or feeding devices with different end connector sizes, thereby extending the usability and functionality of the feeding apparatus.

In some embodiments, after a feeding process is complete, the methods of the present invention may include the step of disconnecting the food pouch from the feeding device to facilitate cleaning, storage, or the preparation of a new feeding session. Once the food pouch is disconnected from the feeding device, a one-way valve integrated within the food pouch or the connector may be automatically or manually engaged to seal the viscous food remaining inside the pouch. This one-way valve prevents contaminants from entering the food pouch, thus preserving the freshness and safety of the viscous food for future use. The design of the one-way valve only allows food to flow out during feeding and completely seals the food pouch when the feeding device is disconnected, thereby reducing the risk of exposure to air, bacteria, or other contaminants.

In addition to the one-way valve, the method may further involve placing a cap over the valve or the open end of the food pouch to provide an additional layer of protection. The cap may be designed to snap securely onto the valve or connector, providing that no food can leak out and that the food pouch is fully sealed. The use of a cap not only protects the food from external contaminants but also helps to maintain the integrity of the one-way valve, preventing any accidental openings or spills during handling or storage. The cap may be integrated with or provided as part of the food pouch sold in the market, providing compatibility and ease of use with the feeding system.

DETAILED DESCRIPTION

The present disclosure provides generally for apparatus and methods for feeding a young or physically inhibited person by dispensing viscous food directly from a food container onto a feeding device including a spoon or other feeding surface. The viscous food container may be removably attached to the feeding device such that during a meal the feeding device remains attached to the food container and following the meal, the spoon may be detached from the container and the food container may be sealed.

In some embodiments of the present invention, an adaptable feeding system that incorporates a graduated connector designed to securely and efficiently connect varying sizes of food containers and feeding devices, is illustrated. The invention addresses the need for a versatile and user-friendly feeding apparatus that can accommodate a wide range of viscous foods and feeding scenarios, making it particularly suitable for infants, young children, and physically inhibited adults. The graduated connector serves as the central component of the system, featuring multiple connector steps that allow for easy attachment of food containers and/or feeding devices of different sizes. These connector steps may utilize various attachment mechanisms, such as snap-fit or threaded connections, to provide a reliable and leak-proof interface between the components. Whether integrated directly into the feeding device or functioning as a standalone unit, the graduated connector provides flexibility and adaptability, enabling users to seamlessly switch between different feeding tools and food containers based on the specific requirements of each feeding session.

In preferred embodiments, the viscous food passes through at least one one-way valve that only permits the viscous food to pass in a single direction of travel and prevents contaminants from entering into the food container. Further, some embodiments may include multiple one-way valves that use a small quantity of viscous food dispensed between the multiple valves to function as a seal and further prevent contaminants from entering the food container.

Embodiments of the present disclosure may include a method of feeding a person incapable of feeding themselves, the method including the steps of connecting a food container containing viscous food in an interior of the food container to the feeding device including the feeding surface exterior to the food container. Embodiments may also include applying compressive force to an exterior surface of the food container.

Embodiments may also include using the compressive force to expel an amount of the viscous food from the interior of the food container through a one-way valve to an exit path from the food container. At least some of the expelled viscous food will be caused to flow onto the feeding surface of the feeding device. The viscous food on the feeding surface may then be fed to the person for consumption. Following a meal provided during a feeding session, the food container may be disconnected from the feeding device and the food remaining in the food container can be sealed in the food container with a cap.

In some embodiments of the present invention, the feeding system is designed to utilize a snap-fit mechanism for securely attaching a food container to a feeding device. The snap-fit mechanism enhances the case of use and reliability of the system, providing a secure connection that can be effortlessly engaged and disengaged, making the feeding process smoother and more efficient for both caregivers and users.

The snap-fit mechanism involves two key components: a snap-fit part on the food container (and on the feeding device in some embodiments) and a corresponding snap-fit part on the graduated connector. The mechanism can be configured in various ways to accommodate different design preferences and functional requirements. For example, the snap-fit part on the graduated connector can be designed as a pin or protrusion that automatically engages with a corresponding recess or hole on the food container end connector (or the feeding device end connector) when the two components are pressed together.

In another embodiment, the snap-fit mechanism may include a spring-loaded pin on the interior (or exterior) surface of the graduated connector, which is associated with a spring-loaded button. When the food container is pressed onto the graduated connector, the spring-loaded pin automatically snaps into the corresponding recess on the food container, securing the connection. To disconnect the food container, the user simply presses the spring-loaded button, which retracts the pin and releases the connection, allowing the food container to be easily removed.

In another embodiment, the roles of the pin and recess can be reversed, with the pin located on the interior (or exterior) surface of the food container end connector and the recess on the exterior (or interior) surface of the graduated connector. This reversed configuration functions similarly, with the pin on the food container end connector snapping into the recess on the graduated connector when the two components are pressed together.

In some embodiments of the present invention, the feeding system employs a threaded mechanism for securely connecting a food container to a feeding device. The threaded mechanism offers a reliable and straightforward method of attachment, allowing the components to remain securely fastened during the feeding process, while also allowing for easy disassembly when needed.

The threaded mechanism involves two main components: the food container end connector and the graduated connector. The food container end connector is designed with a threaded interior or exterior surface, depending on the specific configuration of the system. Correspondingly, the graduated connector is designed with matching threaded patterns on its exterior or interior surface. These threads are engineered to interlock when the food container and feeding device are connected, creating a secure and leak-proof seal.

In some embodiments, the food container end connector includes internal threads that align with external threads on the graduated connector steps. To attach the food container, the user aligns the two components and rotates the food container in a clockwise (or first) direction. As the food container is rotated, the threads on both components engage, drawing the food container end connector closer to the graduated connector until a tight, secure connection is achieved. The threaded mechanism also allows for easy disassembly. To disconnect the food container from the feeding device, the user simply rotates the food container in the counterclockwise (opposite or second) direction. This action disengages the threads, allowing the food container to be easily removed from the graduated connector.

In another embodiment, the positions of the threads can be reversed, with the food container end connector featuring external threads that engage with internal threads on the graduated connector. This configuration functions similarly, with the threaded components interlocking as the food container is rotated into place. The choice between internal and external threading can be made based on design preferences, the type of food container used, or specific functional requirements of the feeding system.

In some embodiments of the present invention, a standalone graduated connector is utilized to facilitate the connection between a feeding device and a food container, employing a combination of snap-fit and threaded mechanisms to provide secure and adaptable attachment. The standalone graduated connector may feature a series of connector steps on both sides, designed to accommodate different sizes of feeding devices and food containers. On the side intended for attachment to the feeding device, each connector step may be equipped with either a snap-fit mechanism or a threaded mechanism, depending on the specific requirements of the feeding system.

In some embodiments, the feeding device is equipped with a feeding device end connector that can be securely attached to the standalone graduated connector using a snap-fit mechanism (similar to the snap-fit mechanism discussed for food containers). In other embodiments, the feeding device end connector may employ a threaded mechanism for attachment to the standalone graduated connector (similar to the grooved or threaded mechanism discussed for food containers).

Referring now to FIGS. 1 and 2, illustrations are shown depicting the main components of a feeding apparatus 100 for implementing some embodiments of the present invention. The feeding apparatus 100 includes a food container 110 and a feeding device 130. The food container 110 and the feeding device 130 are removably attachable to each other by a connector 150. The connector 150 may be a graduated or stepped connector comprising a plurality of connector steps. As described in additional detail below, during use, a person, for example using the person's hand or thumb 170, can compress the food container 110 and expel viscous food 116 onto a feeding surface 134 of the feeding device 130.

The food container 110 includes a food storage portion 112 that forms a cavity 114 and has an exterior surface 118. The cavity 114 of the food storage portion 112 is configured for containing the viscous food 116. The food container 110 further includes a food container end connector 152 that is adapted to connect with one of the connector steps of the graduated connector 150, providing a snug fit irrespective of the size of the food container. The food container end connector 152 is arranged on an open end of the food storage portion 112 and can be understood to be one component of the connector 150.

The food storage portion 112 may be a food pouch, or other compressible container that forms the cavity 114, and allows compressive force to be applied such that viscous food 116, contained in the cavity 114, is expelled by the compressive force. In an example, the compressive force can be applied by a person (e.g., a parent or a caregiver), for example, by squeezing or pressing down on the exterior surface 118 of the food storage portion 112 with a hand or thumb 170.

In some preferred embodiments, the food container end connector 152 will be in fluid communication with one or more one-way valves 202, 204 (FIG. 2) that allow the viscous food 116 to flow out of the food storage portion 112 but prevent material (including contaminants) from entering into the food storage portion 112. Pressure from the person dispenses the viscous food 116 out of the food storage portion 112 via the food container end connector 152, and through the connector 150, which then guides the viscous food onto the feeding surface 134 of the feeding device 130. In this way, the food storage portion 112 in the food container 110 is in fluid communication with the feeding surface 134.

The feeding device 130 includes a feeding portion 132 and a feeding device end connector 154. The feeding portion 132 includes a feeding surface 134. The feeding device 130 is configured to be removably attachable to the food container 110 via the feeding device end connector 154 and the graduated connector 150. During use, the viscous food 116 expelled from the food container 110 passes through the feeding device end connector 154 (which may be wholly or in part overlapping with the food container end connector 152) and onto the feeding surface 134 of the feeding portion 132.

The connector 150 includes the food container end connector 152 and the feeding device end connector 154. The food container end connector 152 and the feeding device end connector 154 are configured to be easily attachable and detachable. The connector 150 will preferably be a quick connect device, such as a Luer lock connector, or almost any other fluidic quick disconnect apparatus.

Following a meal, the feeding device 130 may be disengaged (detached) from the food container 110 and a cap 160 may be attached to the food container end connector 152 to seal any viscous food remaining in the food storage portion 112. Subsequently, the feeding device 130 may be reconnected to the food container 110 for a next meal.

In some preferred embodiments, two (or more) one-way valves 202, 204 may be positioned to trap viscous food 116 within the connector portion such that the trapped viscous food becomes a seal against any contaminants from entering the food storage portion 112 of the food container 110. The trapped viscous food 116 may then be expelled and discarded at the start of a next subsequent feeding session. In this manner, a more secure seal is made and maintained in between meals.

Referring now to FIG. 3, an alternative feeding apparatus 300 includes a food container 310 and a feeding device 330.

The food container 310 can be a syringe style container including a food storage portion 312 and a plunger 316. The food storage portion 312 forms an interior cavity 314. The plunger 316 is configured to respond to compressive force to move the plunger 316 into the food storage portion 312 and expel the viscous food 116 from the cavity 314. An end 318 of the food container 310 can be configured to be removably attachable to the feeding device 330 via a connector 354 on an end of the feeding device 330.

The feeding device 330 is like the feeding device 130 and includes a feeding portion 332 and a feeding device end connector 354. The feeding portion 332 includes a feeding surface 334. The feeding device end connector 354 is configured to be removably attachable to the end 318 of the food container 310.

During use, the viscous food 116 expelled from the food container 310 by application of force on the plunger 316 passes through the end 318 of the food container 310 and onto the feeding surface 334 of the feeding portion 332.

Preferably the syringe type food container 310 will include one or more one-way valves 202, 204 as described in reference to the food container 110, that prevent contaminants from entering the food storage portion 312. For example, the one or more one-way valves 202, 204 may be included in the end 318 of the food container 310.

After use, the feeding device 330 can be removed from the food container 310, and a cap 360 can be attached to the food container 310 to seal the food container 310 from outside contaminants.

Referring now to FIG. 4, an exemplary viscous material sealing area 404 is incorporated into a connector such as the food container end connector 152 operative to connect a food storage container (e.g., the food storage container 110 of FIG. 1) with a feeding device (e.g., the feeding device 130 of FIG. 1). The viscous material sealing area 404 will preferably include two or more one-way valves 204A, 204B to contain a fixed amount of the viscous food 116 in a viscous material sealing area 404 between the one-way valves 204A, 204B. The viscous food 116 contained in the viscous material sealing area 404 during storage can act as a barrier to contaminants from passing through the one-way valves 204A, 204B and entering into the food storage area (e.g., the food storage portion 112 in FIG. 1). The sealed viscous food 116 may be expelled prior to a next meal being dispensed from the compressible food storage container. As shown in FIG. 4, the one-way valves 204A-204B may be realized with valve flap seals 402.

FIGS. 4A and 4B illustrate different valve types that may be in fluid communication with a food storage portion (item 112 in FIG. 1). FIG. 4A illustrates a plated one-way valve 406. FIG. 4B illustrates multiple types of silicon one-way valves 408 that may be included in various implementations of the present invention. A one-way valve is preferably operational to allow viscous food to exit a compressible food container when compressive pressure is applied to a connected compressible food storage container sufficient to generate an expelling (outward) force on the viscous food that exceeds a predetermined threshold force to traverse a one-way valve in fluid communication with the compressible food storage container. The expelling force opens the one-way valve, into an open position, and moves at least a portion of viscous food from within the compressible food storage container through the one-way valve and onto a feeding surface. As the expelling force is relieved, the one-way valve will close into a closed position.

With the one-way valve in a closed position, the one-way valve preferably hygienically seals the viscous food from a potentially contaminating ambient environment and simultaneously impedes the viscous food from escaping the compressible food storage container.

Referring now to FIG. 5, according to the present invention, a single source of viscous food 116 (e.g., the food container 110 of FIG. 1) may be attached to multiple different feeding devices. For example, the feeding devices 130 may be of different sizes, such as the feeding devices 130A and 130B.

The feeding device 130A includes a connector 154, a feeding portion 132A and a feeding surface 134A, and may be large and configured for use by an adult. The feeding device 130B includes the connector 154, a feeding portion 132B and a feeding surface 134B, and may be smaller than the feeding device 130B and is configured for use by an infant or small child. The feeding devices 130 may further include different shapes, types, and materials.

With feeding devices 130 of different sizes and shapes, people of different sizes and needs may hygienically share a single source of food. For example, a child and an adult may attach disparate feeding devices 130 in a serial fashion to the food container 110 and each have a meal from the single source without exchanging germs, viruses, or other contaminants.

In another aspect, a single person may use disparate feeding devices 130 at subsequent meals such that each meal may be had with a clean feeding device 130. For example, each feeding device 130 may be individually packaged and kept sterile (or at least very clean) up until a time of use. Following a meal, the feeding device 130 may be discarded or set aside for cleaning at a subsequent time and a new (clean) feeding device 130 may be used for a current meal. This approach allows for hygienic feeding practices, reducing the risk of contamination and providing the user with access to a clean feeding device for every meal.

As discussed above, preferred embodiments include a connector 150 fitted with two or more one-way valves 202, 204 configured to secure viscous food 116 in between the one-way valves 202, 204 and form a temporary seal. For example, the connector 150 may include a food container end connector 152 and the two or more one-way valves may be included in the food container end connector 152. The viscous food 116 forming the seal can be expelled and discarded prior to a subsequent feeding involving the food container 110 dispensing viscous food 116 onto the feeding surface 134.

Referring now to FIG. 6, a flowchart illustrates an exemplary method 600 of feeding a person, according to some embodiments of the present disclosure. At step 602, the method 600 includes removably connecting a food container containing viscous food in a cavity of the food container to a feeding device comprising a feeding surface exterior to the food container. For example, the food container 110 containing the viscous food 116 in the cavity 114 can be removably connected to the feeding device 130.

At step 604, the method may include applying compressive force to an exterior surface of the food container, for example, the food container 110. The compressive force can be applied using a hand or thumb to squeeze the container, pushing the viscous food toward the connector.

At step 606, the method 600 may include, responsive to the compressive force, expelling an amount of the viscous food from the cavity of the food container through a one-way valve through a connector. For example, the viscous food 116 can be expelled from the cavity 114 of the food container 110 through a one-way valve 204 included in that connector 150. This expulsion allows the food to be delivered in a controlled manner, preventing any backflow or contamination.

In some embodiments, at step 608, the method 600 may include flowing at least some of the expelled the viscous food onto the feeding surface, for example, the viscous food 116 onto the feeding surface 134. The food flows smoothly onto the feeding surface, ready for consumption by the person.

At step 610, the method 600 may include providing the viscous food 116 on the feeding surface 134 to the person. The person can then consume the food directly from the feeding surface, which is designed for easy feeding.

At step 612, the method 600 may include disconnecting the food container from the feeding device, for example, disconnecting the food container 110 from the feeding device 130.

At step 614, the method 600 may include closing the one-way valve thereby sealing the viscous food in the cavity of the food container from contaminants exterior to the food container. For example, the one-way valve 204 may seal the viscous food 116 in the cavity 114 of the food container 110.

At step 616, the method 600 may include capping the one-way valve and protecting the viscous food interior to the food container from contamination from an outside source. For example, the food container 110 may be capped with the cap 160, thereby protecting the viscous food 116 in the cavity 114 of the food container 110.

The method 600 is described above in reference to the feeding apparatus 100. This is only by way of example and is not intended to be limiting. The method 600 can be similarly applied to other embodiments of the feeding apparatus.

Referring now to FIG. 7, a cutaway view and a perspective view are provided of some embodiments of a feeding device 730 that include a reed valve 736 to control a flow of viscous food 116 from a food channel 738 onto a feeding surface 734 of a feeding device 730 (comprising a feeding portion 732). The reed valve 736 is functional to be in a default closed state that prevents food from flowing without additional pressure applied to the flow of food, such as, by way of example, compressive pressure on a food container (not illustrated) attached to a connector 754. The feeding device 730 includes a feeding device end connector 752 that removably attaches to the connector 754. As pressure is applied to the viscous food 116 to flow through the reed valve 736, the reed valve 736 opens, and viscous food 116 is pushed onto the feeding surface 734. When pressure is released from the viscous food 116, the reed valve 736 closes.

Viscous food 116 may be consumed off of the feeding surface 734, such as via feeding a child or disabled person (or another consumer, including an animal). Additional viscous food 116 may be pushed through the reed valve 736 and onto the feeding surface 734 for additional feeding cycles. A cycle of pushing viscous food 116 through the reed valve 736, causing the reed valve 736 to open, ceasing to push the viscous food 116 thereby sealing the reed valve 736, removing viscous food 116 from the feeding portion 732, and pushing additional viscous food 116 through the reed valve 736 to repeat the cycle may be accomplished multiple times.

Referring now to FIG. 8, an exemplary feeding system 800 is illustrated. The feeding system 800 comprises a plurality of food containers 810A, 810B, and 810C, each with varying mouth sizes. The food container 810A includes a narrower mouth or opening 852A, whereas the food container 810C features a larger mouth 852C. Additionally, the food container 810B may comprise an intermediate-sized mouth 852B. The feeding system 800 further comprises different sizes of feeding devices 830A and 830B.

The feeding device 830A includes a feeding portion 832A, a feeding surface 834A, and a stepped or graduated feeding device end connector 854. Similarly, the feeding device 830B includes a feeding portion 832B, a feeding surface 834B, and a stepped or graduated feeding device end connector 855. The connector 854 may be composed of multiple stepped/graduated portions 854A, 854B, and 854C, designed to interface or connect with the varying mouth sizes of the food containers 810A, 810B, and 810C. Correspondingly, the connector 855 may also be composed of multiple stepped/graduated portions 855A, 855B, 855C, and 855D, adapted to connect with the different sizes of food containers (e.g., 810A, 810B, and 810C).

The feeding system 800 addresses the need for versatility in feeding apparatuses by accommodating various food container mouth sizes through its innovative stepped connector design. For example, the food container 810A with its narrower mouth 852A can securely attach to the smallest step 854A (or 855A) of the connector 854 (or 855) on the feeding device 830A (or 830B). This configuration allows for a secure fit, minimizing the risk of leaks or disconnections during use.

Similarly, the intermediate-sized mouth 852B of the food container 810B may be designed to connect with the intermediate step 854B on the connector 854, providing a robust connection that facilitates efficient food transfer. The largest mouth 852C of the food container 810C may fit with the largest step 854C on the connector 854, providing compatibility across a range of container sizes.

The feeding device 830B functions in a comparable manner, with its connector 855 accommodating various mouth sizes of food containers. The smallest step 855A interfaces with narrower mouths such as 852A, the intermediate step 855B connects with medium-sized mouths such as 852B, and the largest step 855C fits larger mouths such as 852C. This stepped or graduated design of the connectors 854 and 855 allows the feeding devices to be used with a wide range of food containers, enhancing their versatility and utility.

The feeding portions 832A and 832B, along with the feeding surfaces 834A and 834B, are integral components of the feeding devices 830A and 830B. These portions are designed to facilitate the transfer of viscous foods from the food containers 810A-810C to the user efficiently. The feeding surfaces, which may take the form of spoon-like structures, are designed to handle the flow of viscous foods, allowing the food to be delivered smoothly and effectively.

The use of multiple stepped portions in the connectors 854 and 855 provides several advantages. Firstly, it allows for a single feeding device (e.g., 830A) to be compatible with multiple food containers (e.g., 810A-810C), reducing the need for multiple feeding tools and simplifying the feeding process for caregivers. Secondly, the graduated design provides a secure fit regardless of the food container size, which may be useful for maintaining hygiene and preventing spills.

For example, in a practical scenario, a caregiver might use the feeding device 830A with the food container 810A for an infant who requires small, controlled portions. The same feeding device 830A can then be used with a different food container, such as 810C, for an older child or adult by simply connecting to a different step (e.g., 854C) on the connector 854. This flexibility may particularly be beneficial in settings where multiple individuals with different feeding needs are being cared for.

The design considerations of the connectors also take into account the case of cleaning and maintenance. The stepped portions (854A-854C and 855A-855D) are configured to be easily accessible, allowing thorough cleaning to prevent the buildup of food residues that can lead to contamination. The materials used for the connectors and feeding surfaces are chosen for their durability and safety, allowing the devices to withstand repeated use and sterilization.

Furthermore, the graduated design of the connectors 854 and 855 enhances the user experience by simplifying the process of connecting and disconnecting food containers. The clear delineation of steps allows users to quickly identify the appropriate connection point for a given container, streamlining the feeding process and reducing preparation time.

The illustrated steps 854A-854C and 855A-855D in connectors 854 and 855, respectively, serve merely as exemplary representations within the scope of this feeding system 800. These specific configurations depict connectors with three and four graduated steps respectively to facilitate attachment to varying sizes of food container mouths. However, it is contemplated that the design of these connectors is not limited to three or four steps. Depending on the specific application requirements, connectors 854 and 855 may be constructed with more than three or four steps to provide a wider range of compatibility with diverse food container sizes. Conversely, they may also feature fewer than three steps where only a limited range of container sizes needs to be accommodated. This adaptability allows that the connectors can be tailored to meet specific user needs and preferences, offering a versatile and flexible solution that can be customized to suit different feeding scenarios and container specifications.

The food containers 810A, 810B, and 810C depicted in FIG. 8 serve as exemplary illustrations within the scope of this feeding system 800. These containers, each with distinct mouth sizes (852A, 852B, and 852C respectively), represent only a subset of possible configurations. It is to be understood that the design is not limited to these specific examples. Various other food containers with different mouth sizes and shapes can also be integrated into this system. The connectors are designed to adapt to a wide array of container specifications, providing compatibility with an extensive range of food container designs beyond those illustrated.

The food containers (e.g., 810A, 810B, and 810C) may include, but are not limited to, different types of commercially available pouches and bottles used for a variety of food products. For example, food containers can encompass pouches used for baby food purees, which often come in small, squeezable formats designed for infants and toddlers. These pouches typically have narrow spouts to facilitate easy feeding and reduce spillage. Examples may include pouches containing apple sauce, mixed fruit purees, vegetable blends, and yogurt.

In addition to baby food, the feeding system can be adapted to accommodate containers of various juices, such as orange juice, apple juice, and mixed berry juice. These juice containers often come in both small, child-friendly sizes with narrower openings and larger family-sized pouches or bottles with wider mouths. Milk containers are another example, ranging from small, single-serving cartons or bottles designed for young children to larger, multi-serving jugs for household use. These containers can include cow's milk, almond milk, soy milk, and other dairy or non-dairy milk alternatives, each with distinct mouth sizes.

Other examples may include but are not limited to apple sauce containers ranging from small pouches to larger jars, yogurt containers for spoon-feeding or squeezable tubes, liquid nutrition supplement bottles and pouches for adults, smoothie pouches with narrow spouts and larger bottles, and containers for sauces and condiments like ketchup and mayonnaise. The system can also adapt to single-serving and family-sized soup containers, various baby formula bottles, and snack containers for pudding or gelatin.

In some embodiments of the present invention, the steps 854A-854C and 855A-855D may be configured to accommodate different types of liquid foods. For example, juices with less viscosity may pass through the smaller openings of the smaller steps, such as 854A or 855A, while thicker, more viscous foods may require the wider openings of the larger steps, such as 854C or 855D.

The feeding system may function by allowing the appropriate food container to be securely attached to the correct step of the connector 854 or 855, based on the viscosity of the food and the size of the container's mouth. For example, a container of apple juice, which has low viscosity, can be connected to the smallest step 854A or 855A. In contrast, containers with thicker, more viscous foods such as yogurt, applesauce, or pureed vegetables may require the larger steps 854C or 855D. These larger openings may be designed to allow the denser food to pass through without clogging or requiring excessive pressure. For example, a pouch of yogurt can be securely attached to step 854C, allowing the food to flow smoothly onto the feeding surface 834A without needing excessive force that may otherwise compromise the feeding experience.

The steps 854B and 855B, representing intermediate sizes, may be suitable for foods with medium viscosity, such as fruit smoothies or blended soups. These foods are thicker than juice but less viscous than yogurt or pureed vegetables. By connecting these containers to the intermediate steps, users can achieve an optimal flow rate that balances the case of dispensing with the need to control the food's passage through the feeding device.

The feeding portions 832A and 832B, along with the feeding surfaces 834A and 834B, are designed to handle the varying flow rates and viscosities of the foods being dispensed. The feeding surfaces are shaped to allow the food, whether liquid or viscous, to be delivered smoothly and efficiently to the user's mouth. This design consideration is particularly important for young children and physically inhibited adults who may have difficulty managing inconsistent flow rates or uneven food textures.

In FIG. 8, the feeding devices 830A and 830B are depicted as being fixedly attached to the connectors 854 and 855, respectively. However, in some embodiments, these feeding devices can also be designed to be removably attachable to the connectors, similar to how food containers 810A, 810B, and 810C can be attached on the opposite side. For example, feeding device 830A, which includes the feeding portion 832A and the feeding surface 834A, can be designed with a connector mechanism that allows it to be securely but removably attached to connector 854. Similarly, feeding device 830B, with feeding portion 832B and feeding surface 834B, can also be designed to connect and disconnect from connector 855. This may provide the same benefits of easy cleaning, replacement, and flexibility. For example, a caregiver may start a feeding session using a small spoon-like feeding device for a baby and then switch to a larger spoon for an older child or adult by simply detaching one feeding device and attaching another.

The steps (854A-854C and 855A-855D) of the connectors 854 and 855, which enable the attachment of various food containers, may also be referred to by alternative terms such as Stages, Levels, Rungs, Gradations, Phases, Intervals, Segments, Tiers, or Progressions. These terms reflect the graduated nature of the connectors, designed to accommodate different sizes and types of food container mouths. Each Stage or Level of the connector may provide a specific diameter that provides a secure fit for a corresponding food container, facilitating the effective and hygienic dispensing of various liquid and viscous foods.

Referring now to FIG. 9, another exemplary feeding system 900, featuring a standalone connector 950, is illustrated. The standalone connector 950 incorporates a plurality of steps on both sides to facilitate the attachment of various food containers and feeding devices. This design enhances the versatility and adaptability of the feeding system, allowing it to accommodate a wide range of sizes and types of food containers and feeding devices.

The connector 950 is centrally positioned within the feeding system 900 and features multiple stepped or graduated segments designed for secure, removable attachment. On the left side (first side) of the connector 950, steps 953, 953A, and 953B (collectively referred to as the first set of connector steps), are configured to interface with different sizes of food containers, for example, 910A and 910B. Each food container is equipped with a food container end connector, e.g., 952A for container 910A and 952B for container 910B, allowing them to attach securely to the appropriate step on the connector 950.

Food container 910A, for example, can be connected to step 953B on the left side of the connector 950. The connector step 953B may be designed to fit the specific mouth size (952A) of container 910A, providing a tight and secure connection that prevents leaks and facilitates the smooth flow of food. Similarly, food container 910B, which may have a different mouth size (952B), can be attached to the connector step 953A.

On the opposite side (right or second side) of the connector 950, the connector steps 951, 951A, and 951B (collectively referred to as the second set of connector steps), are designed to connect various sizes of feeding devices, for example, 930A, 930B, and 930C. Each feeding device is equipped with a feeding device end connector, namely 954A for feeding device 930A, 954B for feeding device 930B, and 954C for feeding device 930C. The connector steps 951, 951A, and 951B allow the feeding devices of different sizes and shapes to be securely attached to the connector 950.

Feeding device 930A, which includes a feeding portion 932A and a feeding surface 934A, can be connected to step 951B on the right side of the connector 950. The connector step 951B may specifically be designed to fit the end connector 954A of feeding device 930A, providing a stable and secure attachment for efficient feeding. Similarly, feeding devices 930B and 930C, with feeding portions 932B and 932C and feeding surfaces 934B and 934C respectively, can be attached to the connector steps 951A and 951 respectively.

The design of the connector 950, with its multiple steps on both sides, allows for significant flexibility in the feeding system 900. For example, a caregiver can easily switch between different food containers and feeding devices by simply attaching them to the appropriate steps on the connector 950. This modularity may particularly be useful in diverse feeding scenarios, where different types of food and feeding devices are needed for various users or different stages of a feeding session.

For example, a caregiver may begin a feeding session with container 910A attached to the connector step 953B, dispensing a liquid food such as juice through feeding device 930A connected to the connector step 951B. If the next part of the meal involves a thicker food like yogurt, the caregiver can quickly switch to container 910B attached to the connector step 953A, and use the feeding device 930B connected to the connector step 951A. This seamless transition between different containers and feeding devices enhances the practicality and efficiency of the feeding system 900.

Additionally, the use of removable attachments for both food containers and feeding devices allows that all components can be easily disassembled for thorough cleaning. This may be useful for maintaining hygiene and preventing cross-contamination, especially when the feeding system is used for multiple types of food or by different individuals. The durable, food-safe materials used for the connectors and feeding devices also allow the system to withstand repeated use and cleaning without compromising functionality.

The steps or stages, on the connectors, may be designed to handle varying viscosities and flow rates of different foods. For example, narrower steps such as 953B and 951B may be suitable for less viscous foods like juices, providing controlled flow and easy dispensing. Wider steps like 953A, 951A, may accommodate thicker foods such as purees and yogurts, allowing these denser foods to pass through without clogging or requiring excessive pressure.

In some embodiments of the present invention, the feeding devices 930A-930C may be designed to cater to different individuals, with variations in size and configuration to suit specific needs. Feeding device 930A, for example, may be smaller in size and may particularly be suitable for infants or young children. The feeding device 930A may comprise a smaller feeding portion 932A and a smaller feeding surface 934A, designed to facilitate gentle and manageable feeding for younger users. The feeding device 930B may be moderately sized, making it ideal for older children. It may include a moderately sized feeding portion 932B and a moderately sized feeding surface 934B, which are designed to handle slightly larger volumes of food, appropriate for the increased feeding requirements of this age group.

Feeding device 930C is larger and may be suitable for adults or physically inhibited individuals who require more substantial food portions. The feeding device 930C may include a larger feeding portion 932C and a larger feeding surface 934C, providing the necessary capacity and flow rate for adult feeding needs.

Each of these feeding devices, 930A, 930B, and 930C, is equipped with a feeding device end connector (954A, 954B, and 954C respectively). The connectors 954A, 954B, and 954C may be fixedly attached to their respective feeding devices, providing a secure and stable connection during use. The feeding device end connectors 954A, 954B, and 954C may be designed to fit into the steps (951, 951A-951B) of the standalone connector 950, allowing for seamless attachment and detachment as needed.

The feeding device end connectors 954A-954C may vary in size irrespective of the size of the feeding devices (930A-930C) themselves. For example, the smaller feeding device 930A may have a smaller feeding device end connector 954A, suitable for attaching to narrower steps on the connector 950. Alternatively, the smaller feeding device 930A may have a larger feeding device end connector (e.g., similar to 954B-954C), allowing it to be used with wider steps if required by the specific feeding scenario.

Similarly, feeding device 930B, which is of moderate size, may feature a feeding device end connector 954B that may be smaller, fitting narrower steps, or larger, fitting wider steps, depending on the needs of the user and the type of food being dispensed. This flexibility allows the feeding system 900 to be customized to suit various feeding situations and container types.

Feeding device 930C, being the largest, may typically have a larger feeding device end connector 954C to match its capacity. However, it can also be designed with a smaller feeding device end connector (e.g., similar to 954A-954B) if it needs to be attached to narrower steps on the connector 950 for specific feeding applications. This adaptability provides significant versatility in the feeding system, accommodating a wide range of food viscosities and container sizes.

The ability to pair any feeding device with any size end connector enhances the practicality of the system. For example, if a caregiver needs to switch from feeding an infant with device 930A to feeding an older child with device 930B, they can easily do so by attaching the appropriate end connector to the connector 950. The fixed attachment of the end connectors 954A-954C to their respective feeding devices 930A-930C allows the components to remain securely connected during feeding, reducing the risk of spills and contamination.

In some embodiments, the connector steps 951 and 953 can be designed as either a combined, single component or as separate sections divided by a raised portion or line 955. This configuration may allow larger feeding device end connectors (e.g., 954C) and larger food container end connectors (e.g., 952B) to be removably attachable to the connector steps 951 and 953 on opposite ends up to the raised portion 955. Such a design may provide a secure and flexible attachment for both feeding devices and food containers, accommodating a range of sizes while maintaining the integrity and stability of the connections.

The feeding device end connectors 954A-954C can be made from a variety of materials to provide durability, safety, and ease of use. Possible materials may include, but are not limited to, food-grade silicone, which offers flexibility and a secure seal; stainless steel, known for its strength and resistance to corrosion; high-density polyethylene (HDPE), which is durable and resistant to chemicals; polypropylene, valued for its toughness and heat resistance; and thermoplastic elastomers (TPE), which provide a combination of flexibility and durability. Additionally, materials such as polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS) can be used for their robustness and case of molding into precise shapes, while materials like nylon and polycarbonate offer excellent mechanical properties and high impact resistance. These materials may allow the connectors to be safe for food contact, easy to clean, and capable of withstanding repeated use and sterilization processes.

The feeding portions 932A-932C and feeding surfaces 934A-934C, which are designed to be inserted into users' mouths, must be made from materials that prioritize safety, comfort, and hygiene. Suitable materials may include food-grade silicone, which is soft, flexible, and gentle on gums and teeth; thermoplastic elastomers (TPE), offering a similar softness and flexibility; and food-grade plastic such as polypropylene, which is smooth, durable, and easy to clean. Additionally, medical-grade stainless steel can be used for its non-reactive and hygienic properties, although it is less common for direct oral contact due to its hardness. Materials like BPA-free plastics may also be suitable, allowing that they are free from harmful chemicals. Natural materials like bamboo, known for being eco-friendly and having natural antibacterial properties, can also be considered. These materials provide safe, non-toxic, and comfortable feeding portions and surfaces for users, making them ideal for insertion into user's mouth during feeding.

Referring now FIG. 10, a detailed illustration of an exemplary food-flow mechanism 1000 is illustrated. The food-flow mechanism 1000 showcases how viscous food moves through various steps (1054A-1054C) of a graduated connector 1054 when different sized food containers are connected to it.

A feeding device 1030, which includes a feeding portion 1032 and a feeding surface 1034, is shown attached to one side (right side) of the graduated connector 1054. This attachment can be either fixed or removable, depending on the design embodiment, providing flexibility for different feeding scenarios (as described above in FIG. 9). The feeding device 1030 is responsible for receiving the food flow from the container and delivering it to the user in a controlled manner.

The graduated connector 1054 comprises multiple connector steps, for example, but are not limited to: 1054A, 1054B, and 1054C. The connector steps are designed to accommodate food containers of varying sizes, providing a secure fit and proper alignment for the food flow. While FIG. 10 illustrates three connector steps, it is important to note that more than three or fewer than three steps may be incorporated in other embodiments, depending on the specific requirements of the feeding system.

The graduated connector 1054 includes a series of hollow food-flow paths that facilitate the flow of food through the different connector steps 1054A-1054C. These food-flow paths allow the food to move smoothly from the food containers (1010A-1010C) through the graduated connector 1054 and into the feeding device 1030. For example, the outermost connector step 1054C and the middle connector step 1054B may form a first top food-flow path 1001 and a first bottom food-flow path 1001A. Similarly, the middle connector step 1054B and the innermost connector step 1054A may form a second top food-flow path 1002 and a second bottom food-flow path 1002A. The innermost connector step 1054A itself contains a third food-flow path 1003, which directly channels food from the smallest container 1010A attached to the connector step 1054A into the feeding device 1030.

A plurality of differently sized food containers 1010A, 1010B, and 1010C, can be connected to the appropriately sized connector steps 1054A, 1054B, and 1054C, respectively. The food container 1010A, being the smallest, may removably attach to the connector step 1054A, utilizing the third food-flow path 1003 for direct delivery of viscous food to the feeding device 1030. The medium-sized food container 1010B may be removably connected to the middle connector step 1054B, utilizing the second top and bottom food flow paths 1002 and 1002A, in conjunction with the third food flow path 1003, to efficiently channel food toward the feeding device 1030. Alternatively, the largest food container 1010C may be removably attached to the outermost connector step 1054C, leveraging all available food flow paths-the first top and bottom paths 1001 and 1001A, the second top and bottom paths 1002 and 1002A, as well as the third food flow path 1003, to seamlessly direct food through the graduated connector 1054 and onto the feeding surface 1034 of the feeding device 1030.

The combination of these food flow paths within the graduated connector 1054 allows that regardless of the size of the food container, the food is efficiently directed toward the feeding device 1030. The various hollow paths and connector steps are carefully designed to accommodate the flow characteristics of different types of food, from thin liquids to thicker purees, allowing the feeding system to handle a wide range of food viscosities. This flexibility may be useful for catering to the diverse dietary needs of different users, whether they are infants, young children, or physically inhibited adults.

In some embodiments, the graduated connector 1054 may be equipped with an adjustable flow control mechanism that allows the user to regulate the speed and volume of food being dispensed through the graduated connector 1054 and hence to the feeding device 1030. This mechanism may be integrated into the connector steps 1054A-1054C, providing the ability to fine-tune the flow based on the viscosity of the food and the needs of the user. For example, a sliding valve or adjustable aperture may be incorporated within the food flow paths 1001, 1001A, 1002, 1002A, and 1003, allowing the user to either restrict or increase the flow of food as it moves from the containers (1010A-101C) to the feeding surface 1034. This may particularly be useful for caregivers feeding infants or physically inhibited adults, where precise control over the amount of food dispensed is required. Additionally, this flow control mechanism can be locked into place once the desired flow rate is achieved, providing consistency throughout the feeding session.

Referring now to FIGS. 11A and 11B, exemplary mechanisms for attaching a connector step with food containers and feeding devices are illustrated. FIG. 11A illustrates an exemplary connector step 1150, demonstrating how various food containers and feeding devices can be removably attached using a snap-fit mechanism. FIG. 11A shows a single connector step, but it is understood that similar steps can be part of a graduated connector system that includes multiple steps, each designed to accommodate varied sizes and types of food containers and feeding devices.

The connector step 1150 may be designed with a top sloped portion 1101 and a bottom sloped portion 1102, throughout the interior surface of the connector step 1150. The sloped portions 1101-1102 facilitate the snap-fit connection, allowing both a food container end connector 1152A and a feeding device end connector 1154 to be securely attached at either end of the connector step 1150. The sloped design (1101-1102) helps guide the connectors (1152A & 1154) into place and provides a secure locking mechanism once the connectors are snapped in.

The design of the sloped portions 1101 and 1102 within the connector step 1150, is not limited to just sloped configurations. These portions may be shaped in various ways to accommodate different attachment mechanisms and to enhance the versatility of the connector. For example, the connector step may feature curved, ribbed, or stepped surfaces instead of simple slopes. Curved surfaces can provide a more gradual and secure fit for end connectors (1152A & 1154) with rounded edges, while ribbed surfaces may offer additional grip and prevent slippage. Stepped surfaces may allow for multiple locking positions, accommodating connectors of varying sizes and providing a secure fit regardless of the connector's exact dimensions. These alternative designs may provide flexibility in how the food containers and feeding devices are attached, making the feeding system adaptable to a broader range of products and user preferences, while still providing a secure and reliable connection.

The food container end connector 1152A of a food container 1110A may be designed to snap into the connector step 1150 at one end. Similarly, the feeding device end connector 1154 of a feeding device 1130A may be designed to snap into the opposite end of the connector step 1150.

The connector step 1150 may be made from a material that is moderately flexible, allowing it to expand and contract (shown as Arrow 1111) to accommodate the snap-fit end connectors. The material can be food-grade silicone, thermoplastic elastomer (TPE), or a flexible polymer that can expand between 5% to 50% of the connector step's diameter when the end connectors are inserted. This expansion provides a tight fit around the end connectors, holding them securely in place while still allowing for easy removal when needed.

For example, when the food container end connector 1152A is snapped into the connector step 1150, the sloped portions 1101 and 1102 may gently expand to accommodate the end connector 1152A. As the end connector 1152A slides fully into place, the sloped portions 1101-1102 contract slightly, creating a secure seal that holds the food container 1110A firmly in place. The same process occurs on the opposite end when attaching the feeding device end connector 1154.

This snap-fit mechanism offers significant advantages in terms of usability, particularly for caregivers or parents who may need to operate the feeding system with one hand. For example, a caregiver holding a baby can easily snap the food container and feeding device into place using just one hand, making the process quick and efficient. This is especially beneficial in situations where the caregiver needs to prepare the feeding system while also managing other tasks or attending to the child.

The ability to operate the feeding system single-handedly may also be a useful feature for enhancing user convenience. For example, during a feeding session, a parent may need to quickly switch from one food container to another or attach a different feeding device depending on the type of food being fed. The snap-fit design allows for these adjustments to be made swiftly, without the need to set the child down or interrupt the feeding process.

Moreover, the moderately flexible material of the connector step 1150 provides durability and longevity, withstanding repeated use and the stress of snapping connectors in and out. The flexibility also helps absorb any minor impacts or movements, reducing the risk of the connectors loosening over time. This may allow the feeding system to remain reliable and secure, even with frequent use.

The design of the sloped portions 1101 and 1102 also plays a role in allowing the end connectors to be guided smoothly into place. The sloped surfaces provide a natural guide for the connectors, helping to align them correctly as they are inserted. This reduces the risk of misalignment or damage to the end connectors, further enhancing the ease of use and the overall durability of the system.

FIG. 11B illustrates another exemplary method for attaching a connector step to a food container end connector, specifically focusing on a threaded connection mechanism. FIG. 11B displays a feeding system where a food container 1110B, equipped with a threaded food container end connector 1152B, is securely attached to a graduated connector 1154, which may be fixedly attached to a feeding device 1130B.

The food container 1110B may be designed with a food container end connector 1152B (e.g., a neck of the food container 1110B), which comprises a first threaded pattern 1103 on its outer surface. This threaded pattern is typical of many commercially available food containers, which often come with caps that screw onto the threads to seal the container. When the cap is removed from the food container 1110B, the threaded pattern 1103 is exposed, ready to engage with a corresponding threaded pattern on a connector step of the feeding system.

The graduated connector 1154 comprises three exemplary connector steps: 1154A, 1154B, and 1154C. Each of these connector steps may be designed to accommodate food containers with different sizes of threaded end connectors. The connector steps are arranged progressively, with each step having a slightly different diameter to match the varying sizes of food container connectors.

Each connector step 1154A, 1154B, and 1154C is equipped with a second threaded pattern (1104 on 1154A, 1105 on 1154B, and 1106 on 1154C) on its inner surface. These threaded patterns are designed to engage with the first threaded pattern 1103 on the food container end connector 1152B.

To attach the food container 1110B to the appropriate connector step on the graduated connector 1154, the user aligns the threaded pattern 1103 on the end connector 1152B with the corresponding threaded pattern (e.g., 1104, 1105, or 1106) on the selected connector step, depending on the size of the end connector 1152B. The user then rotates (as shown using an arrow) the food container 1110B in a first direction (e.g., clockwise direction), causing the threads to interlock and gradually pull the food container end connector 1152B into the connector step. As the container 1110B is rotated, the threads guide the end connector deeper into the connector step, creating a tight, secure fit that prevents any leakage of food from the container. The food container 1110B can be easily detached by rotating it in a second or opposite direction (e.g., a counterclockwise direction).

The threaded connection works on the principle of converting rotational motion into linear motion. As the food container is rotated, the helical structure of the threads causes the end connector to move linearly into the connector step, compressing the material slightly and creating a seal. This seal may allow that when the feeding system is in use, the food from the container 1110B flows directly through the graduated connector 1154 and into the feeding device 1130B without any leaks or loss of pressure.

The graduated connector 1154 is designed to be versatile, allowing different sizes of food containers to be attached using the appropriate connector step. For example, if the food container end connector 1152B is relatively large, it may be threaded into the largest step, 1154C, which has the largest diameter and corresponding thread pattern 1106. For a medium-sized end connector 1152B, the connector step 1154B with thread pattern 1105 may be used, and for smaller end connectors (1152B), the connector step 1154A with thread pattern 1104 can be suitable.

The threaded connection mechanism offers several advantages. Firstly, it provides a highly secure attachment, allowing the food container to remain firmly in place during feeding, even if the system is moved or jostled. Secondly, the threaded connection is easy to use, requiring only simple rotation to attach or detach the container, which can be done quickly by the caregiver. Additionally, the threaded design allows for repeated use without significant wear, as the threads are designed to withstand repeated screwing and unscrewing. This durability allows the feeding system to be used multiple times daily.

In an alternative embodiment, the threaded pattern 1103 may be positioned on the inside or interior surface of the food container end connector 1152B, while the corresponding threaded patterns 1104-1106 are located on the outside or exterior surfaces of the connector steps 1154A-1154C. This mechanism may reverse the typical threading arrangement, where the food container 1110B is screwed onto the exterior of the connector step rather than into it.

To attach the food container 1110B to the graduated connector 1154, the user aligns the interior threads 1103 of the end connector 1152B with the internal threads (e.g., 1104, 1105, or 1106) of the selected connector step, depending on a suitable size for the food container 1110B. The user then rotates the food container 1110B in a first direction, causing the external threads 1103 to engage with the internal threads (1104, 1105, or 1106) on the selected connector step. As the container is rotated, the threads 1103 on the interior of the end connector 1152B gradually wind around the internal threads (1104, 1105, or 1106) on the selected connector step, pulling the food container 1110B securely onto the selected connector step.

When it is time to detach the food container, the user simply rotates the container in the opposite direction. This action disengages the internal threads from the external threads, allowing the food container to be easily unscrewed and removed from the connector step. This design offers a secure connection with the added benefit of being intuitive and easy to operate, as it mirrors the familiar action of screwing a lid onto a jar. It also allows the external threads on the connector steps to be more visible and accessible, potentially making the threading process easier to manage, especially for users who may have difficulty aligning internal threads.

In another embodiment, the feeding device 1130B may also be designed to be removably attachable to a graduated connector using a threaded connection mechanism similar to that of the food container, as explained above. The feeding device end connector of the feeding device 1130B can feature a threaded pattern on either its interior or exterior surface, depending on the design, which allows it to be securely attached to a corresponding connector step on the graduated connector.

If the feeding device end connector has a threaded pattern on its interior surface, this internal threading matches with an external threaded pattern on a suitably sized connector step of the graduated connector. The user can align the feeding device with the appropriate connector step and rotate the feeding device in a first direction (which may be clockwise or anticlockwise direction), causing the internal threads of the feeding device end connector to engage with the external threads on the connector step. The rotational motion draws the feeding device end connector securely onto the connector step, forming a tight, leak-proof seal so that the feeding device remains firmly attached during use.

Alternatively, if the feeding device end connector has its threaded pattern on the exterior surface, the corresponding connector step on the graduated connector may feature internal threading. In this case, the user can insert the feeding device end connector into the suitable connector step and rotate it in the first direction. The external threads on the feeding device end connector engage with the internal threads of the selected connector step, again securing the feeding device in place.

Referring now to FIG. 11C, it provides a detailed illustration of an exemplary feeding system, including a feeding device 1130C and a food container 1110C. The figure highlights how these components are connected, in some embodiments, using a graduated connector 1154C with threaded connection mechanisms.

The feeding device 1130C is depicted as having a fixedly attached graduated connector 1154C. The graduated connector 1154C features a series of connector steps, each of which includes threaded patterns 1108 on their exterior surfaces. These threaded patterns are designed to engage with corresponding threads on the food container, providing a secure and leak-proof connection.

The food container 1110C includes a food container end connector 1152C. The end connector 1152C is designed to fit onto the graduated connector 1154C by means of internal threaded patterns 1107. These threads on the interior surface of the food container end connector 1152C are configured to match the external threads 1108 on a suitably sized connector step of the graduated connector 1154C.

To attach the food container 1110C to the feeding device 1130C, the caregiver aligns the food container end connector 1152C with the appropriate connector step on the graduated connector 1154C. Once aligned, the caregiver rotates the food container 1110C in the clockwise (or any other direction) direction, as indicated by the arrow in the figure. This rotation causes the threaded patterns 1107 and 1108 to engage, drawing the food container end connector 1152C closer to the graduated connector 1154C and securing it in place.

The threaded connection provides a tight seal between the food container 1110C and the feeding device 1130C, preventing any leakage of viscous food during the feeding process. Once the feeding session is complete, the food container 1110C can be easily disconnected from the feeding device 1130C by rotating the container in the counterclockwise (opposite) direction. This action unscrews the food container end connector 1152C from the graduated connector 1154C, allowing the user to remove the container without spilling any remaining food.

This threaded connection system provides a reliable and reusable method of attaching various food containers to the feeding device 1130C. It may particularly be useful in situations where multiple types of food containers might be used interchangeably with the same feeding device 1130C, as the graduated connector 1154C can accommodate different sizes and types of food containers, provided they have compatible threaded end connectors.

In some embodiments, the feeding system may be further adapted to include various sizes of food containers, each with its own corresponding threaded end connector. This may allow the feeding device 1130C to be used in a wide range of feeding scenarios, from feeding infants and young children to assisting physically inhibited adults with eating. The threaded connection mechanism allows each container to be securely attached and easily removed, making the system both versatile and user-friendly.

Referring now to FIG. 11D, a detailed view of an exemplary feeding system, focusing on the interaction between a feeding device 1130D and a food container 1110D, is provided. The feeding device 1130D includes a graduated connector 1154D designed with a series of connector steps, each of which is equipped with a snap-fit mechanism part 1108D on its surface. The snap-fit mechanism part 1108D may be a pin, a protrusion, or a raised element that is intended to engage with a corresponding snap-fit mechanism part on the food container 1110D.

The food container 1110D includes a food container end connector 1152D which includes a corresponding snap-fit mechanism part 1107D on its surface, designed to engage with snap-fit mechanism part 1108D. The snap-fit part 1107D may be a hole, a recess, or a slot that matches the pin or protrusion on the graduated connector 1154D.

To connect the food container 1110D to the feeding device 1130D, the caregiver aligns the food container end connector 1152D with the appropriate connector step on the graduated connector 1154D. Once aligned, the caregiver presses the food container end connector 1152D towards the graduated connector 1154D. As pressure is applied, the snap-fit mechanism part 1107D (for example, a hole) engages with the snap-fit mechanism part 1108D (for example, a pin). The pin or protrusion fits into the hole or recess, securing the two components together with a “snap” sound, indicating a successful connection.

The snap-fit connection is designed to provide a secure and stable attachment between the food container and the feeding device. It allows the food container to remain firmly attached during the feeding process, preventing accidental disconnection that can lead to spills or interruptions. The snap-fit design may particularly be advantageous for caregivers who need to quickly and easily assemble the feeding system, such as parents feeding infants or caregivers assisting physically inhibited adults.

One of the benefits of the snap-fit mechanism is that it allows for single-handed operation, making it user-friendly and efficient. For example, a parent holding a baby in one arm can easily connect the food container 1110D to the feeding device 1130D with their free hand, providing a smooth and uninterrupted feeding process.

To disconnect the food container 1110D from the feeding device 1130D, the user can simply apply pressure in the opposite direction. This action disengages the snap-fit mechanism, allowing the food container 1110D to be easily removed from the graduated connector 1154D. The disconnection process is as straightforward as the connection, making it convenient for cleaning, storage, or switching between different food containers.

This snap-fit mechanism also allows for the use of multiple food containers with a single feeding device. Different food containers, each containing a different type of viscous food (such as pureed vegetables, fruit, or yogurt), can be quickly attached and detached from the feeding device as needed. This versatility makes the feeding system adaptable to various feeding scenarios, whether at home, in a childcare setting, or on-the-go.

In some embodiments, the snap-fit mechanism can be designed to accommodate varying levels of force required for connection and disconnection. For example, a stronger snap-fit may be used for scenarios where a more secure connection is needed, such as when feeding a particularly thick or heavy viscous food. Alternatively, a lighter snap-fit may be used for easier disconnection, catering to caregivers who require minimal effort to operate the feeding system.

Additionally, the snap-fit mechanism can be designed with safety features, such as a locking mechanism that prevents accidental disconnection during feeding. This may be particularly useful in settings where the feeding system is used by children or physically inhibited individuals who may not have full control over their movements.

In some embodiments, the snap-fit mechanism part 1107D may be designed as a spring-loaded pin associated with a spring-loaded button (not shown) located on the surface of the food container end connector 1152D. The spring-loaded pin 1107D is designed to automatically engage with the corresponding snap-fit mechanism part 1108D, such as a recess or hole on the surface of each connector step of the graduated connector 1154D. When the food container 1110D is pressed onto a suitably sized connector step of the graduated connector 1154D, the spring-loaded pin 1107D automatically snaps into place within the recess 1108D, creating a secure and firm connection without the need for manual alignment or additional effort. To disengage the connection, the caregiver can simply press the spring-loaded button, which retracts the pin 1107D from the recess 1108D, allowing the food container to be easily removed.

In an alternative embodiment, the design of the snap-fit mechanism parts 1108D and 1107D can be reversed. In this configuration, the pin or protrusion can be located on the interior surface of the food container end connector 1152D (part 1107D), while the corresponding recess or hole is positioned on the exterior surface of the graduated connector 1154D (part 1108D). When the food container 1110D is pressed onto the graduated connector, the pin on the food container end connector 1152D automatically fits into the recess on the graduated connector 1154D, creating a secure snap-fit connection. This reversed design still allows for a reliable and user-friendly attachment, with the added flexibility of being able to customize the placement of the snap-fit components depending on the specific design requirements of the feeding system. The disconnection process remains straightforward, as the caregiver can disengage the pin from the recess by applying pressure (or by pressing a spring-loaded button) in the opposite direction, allowing for easy removal of the food container from the feeding device.

In some embodiments, 11D, a standalone graduated connector is designed to facilitate the connection between a feeding device and a food container, utilizing a snap-fit mechanism for secure attachment. The feeding device, equipped with a feeding device end connector, features a snap-fit part (similar to the food container) that corresponds with the connector steps on one side of the standalone graduated connector. The connector steps on the graduated connector have matching snap-fit mechanisms, such as pins or recesses, allowing the feeding device end connector to be easily and securely attached by simply pressing the feeding device onto the appropriate connector step. This connection provides a stable and reliable attachment during feeding, while also allowing for quick and easy disconnection by applying pressure in the opposite direction. This may be particularly useful in scenarios where different feeding devices need to be rapidly connected or swapped out with the standalone graduated connector, providing versatility and convenience in the feeding process.

Referring now to FIG. 12, an exemplary modular design of a graduated connector 1200 is illustrated. The modular design of the graduated connector 1200 showcases a versatile and adaptable feeding system where the graduated connector 1200 can be constructed with multiple connector steps that can accommodate varying sizes of food containers and feeding devices, making the system highly customizable and user-friendly.

The graduated connector 1200 is depicted with multiple connector steps on each end, specifically designed to fit different sizes of food containers and feeding devices on opposite ends.

On one end, the connector steps 1212-1215 are shown, each step progressively smaller, allowing for the attachment of varying sizes of food container end connectors. For example, connector step 1215 is the smallest, while connector step 1212 is larger, accommodating food containers with different sized openings.

On the opposite end of the graduated connector 1200, additional connector steps 1202-1204 are depicted. These steps are similarly graduated in size and are used for attaching feeding devices of varying sizes. The smallest feeding device may be connected to the smallest step 1204, while larger feeding devices can be connected to the larger steps like 1202.

At the center of the graduated connector 1200 lies the connector step 1201, which may serve a dual purpose. The design allows one half of connector step 1201 to be used for attaching a larger food container end connector, while the other half is used for attaching a larger feeding device end connector (e.g., up to the raised portion, 955 as discussed in FIG. 9).

In some embodiments, each of the connector steps (1201-1204 and 1212-1215) is a modular piece, meaning that these steps can be individually joined together to form the complete graduated connector 1200. This modularity allows users to customize the graduated connector according to their specific needs, attaching or detaching steps depending on the size of the food container or feeding device being used.

For example, if a user only needs to attach a medium-sized food container and a small feeding device, they can select and assemble just the relevant steps (e.g., steps 1213, 1212, 1201 and 1202-1204), rather than using the entire graduated connector. This modular approach not only provides flexibility but also makes the system more compact and easier to clean or store when not all components are needed.

When assembling the modular graduated connector 1200, the user selects the appropriate connector steps based on the sizes of the food container and feeding device they intend to use. These steps are then joined together to form the required connector, with the central connector step 1201 providing a stable base for the larger attachments.

The food container may then be attached to one end of the assembled connector, with the food container end connector fitting snugly into the appropriate connector step (e.g., 1201, 1212-1215). Similarly, the feeding device may be attached to the opposite end, with its feeding device end connector fitting into the suitable step (e.g., 1201, 1202-1204).

The modular design offers significant benefits, particularly in terms of adaptability and user convenience. Caregivers can easily adjust the connector to suit the specific sizes of food containers and feeding devices they have on hand, making the system highly versatile. The ability to disassemble and reassemble the connector also makes it easier to clean, as individual steps can be taken apart and washed separately. Furthermore, the modularity of the system allows for easy replacement of individual connector steps if they become worn or damaged, rather than needing to replace the entire graduated connector.

In some embodiments, the modular pieces 1201-1204 and 1212-1215 of the graduated connector can be selectively connected to each other according to specific needs using various attachment mechanisms. These modular pieces may feature grooved interfaces, snap-fit connections, threaded mechanisms, or any other connections as discussed throughout the invention, allowing them to be easily assembled or reconfigured based on the requirements of the feeding system.

In some embodiments, the graduated connector 1200 may be designed as a telescopic structure, allowing the connector steps 1202-1204 on one side and 1212-1215 on the opposite side to retract (e.g., indicated by arrow directions) into the central connector step 1201. Each connector step may be designed as a retractable segment that slides into or out of the central connector step 1201. The smaller steps are nested within the larger ones, which are then housed within the central step 1201. For example, connector step 1204 may retract into step 1203, which then retracts into step 1202, and finally, step 1202 retracts into the central step 1201. Similarly, on the opposite side, connector step 1215 retracts into 1214, which retracts into 1213, and so on, until all steps are housed within 1201.

The telescopic mechanism operates through interlocking grooves and channels along the interior surfaces of each connector step, guiding the steps as they retract into or extend from the central step 1201. Locking features, such as small tabs or clips, engage when the steps are fully extended or retracted, holding them securely in place to prevent unwanted movement during use. To extend the connector steps, the user pulls on the outermost step, causing the nested steps to slide out sequentially from the central step 1201, locking into place as they reach their full extension, creating a rigid, graduated connector ready for use. When not in use, or if a more compact configuration is needed, the user can retract the steps back into the central connector step 1201 by applying slight pressure and pressing the locking tabs, smoothly pushing the steps back until all are fully nested inside, resulting in a compact, streamlined form.

The telescopic design allows for compact storage and portability, making it easier to store or transport. The ability to adjust the connector's length and the number of steps extended provides flexibility depending on the sizes of the food containers and feeding devices being used. The retraction of the steps into the central step 1201 also protects the connector steps from damage, minimizing exposure to potential impacts or wear and tear, and thereby extending the lifespan of the feeding system. The telescopic mechanism is straightforward to operate, allowing caregivers to quickly and easily adjust the connector as needed, which is particularly important in feeding situations where time and convenience are crucial.

Imagine a scenario where a caregiver is preparing to feed a child while traveling. The caregiver can easily retract the graduated connector 1200 into its most compact form, packing it neatly into a small bag. Upon reaching the destination, the caregiver can quickly extend the necessary connector steps to accommodate a specific food container and feeding device. This process is intuitive and fast, making the feeding system ready for use in a matter of seconds. After the feeding session, the caregiver can retract the steps back into the central step 1201, reducing the size of the connector and making it convenient to store away until the next use. The telescopic structure offers significant advantages in terms of storage, adjustability, and case of use, making it highly adaptable to various feeding scenarios without sacrificing portability or durability.

Referring now to FIG. 12A, it illustrates a modular graduated connector 1200A, which is designed to be adaptable based on the specific requirements of a feeding session. This adaptability is achieved by utilizing a series of individual connector step pieces 1210. Each of these connector step pieces 1210 is modular, meaning they can be selected and assembled in various combinations to create a graduated connector that meets the specific needs of the caregivers. The arrow at the left side of the graduated connector 1200A, shows connector steps for food pouches or varying sizes, and the arrow at the right side of the graduated connector 1200A, shows connector steps for food pouches or varying sizes

The individual connector step pieces 1210 may be designed with threading patterns either on their interior surfaces, exterior surfaces, or both, depending on the particular design and the intended method of connection. The threading patterns allow the pieces to be screwed together securely, forming a continuous graduated connector 1200A. The threading mechanism provides a robust and reliable means of attachment, allowing that once the pieces are connected, they form a stable and unified structure.

The ability to choose the number and size of the connector step pieces 1210 offers significant flexibility. For example, if a feeding session requires a connector that can accommodate both large and small food container end connectors, the user can select a combination of larger and smaller connector step pieces. These pieces can then be assembled in the desired order, creating a customized graduated connector that can securely hold the various sizes of food containers.

Moreover, the modular design of the connector step pieces 1210 also allows that the graduated connector 1200A can be easily disassembled after use for cleaning or storage. It also allows for the replacement of individual connector steps if one becomes worn or damaged, further enhancing the longevity and utility of the system.

Referring now to FIG. 13, a flowchart 1300 of exemplary method steps that may be executed in some implementations of the present invention, is illustrated. The flowchart 1300 outlines a series of actions that guide the use of a feeding device with a fixedly attached graduated connector for feeding a user (a child or an adult). Below is a detailed description of each step in the flowchart:

At step 1302, the process begins with selecting a feeding device that has a fixedly attached graduated connector. The feeding device may be selected based on the specific needs of the user, such as the age, feeding habits, and type of food being served. For example, a feeding device with a larger spoon-like surface may be chosen for an adult, while a smaller, more ergonomically designed device can be selected for a child. The fixedly attached graduated connector provides the advantage of reducing the need for assembly, thereby minimizing the time and effort required to set up the feeding system.

At step 1304, a correct food container is chosen, and a cap is removed from the food container. The food container may be selected based on the type of food it contains, such as liquid, semi-solid, or solid food. For example, if the feeding session involves serving a thick puree, a container designed for dispensing viscous foods may be ideal. After selecting the appropriate food container, the user (e.g., a parent or caregiver) must remove the cap, which typically seals the container to keep the contents fresh and prevent contamination. The removal of the cap exposes the food container's end connector, making it ready for attachment to the graduated connector on the feeding device.

At step 1306, the user (e.g., a parent or caregiver) identifies an appropriate connector step on the graduated connector. The graduated connector comprises multiple steps of varying sizes, each designed to accommodate different sizes and types of food container end connectors. The user must carefully match the size of the food container end connector with the corresponding connector step on the graduated connector. For example, if the food container has a small end connector, the user may select a smaller step on the graduated connector to achieve a snug and secure attachment. This step also allows the user to adjust the feeding system for different types of food containers, offering flexibility and adaptability in various feeding scenarios.

At step 1308, the food container end connector is removably attached to the selected connector step on the graduated connector. This attachment can be achieved through various mechanisms, such as threading, snap-fitting, or a combination of both. The user aligns the food container end connector with the selected connector step and engages the attachment mechanism by rotating or pressing the container into place. The connector step may be designed to expand slightly to accommodate the food container end connector, providing a tight fit that prevents leaks and maintains the integrity of the feeding system. During this step, the user may also verify that the food container is securely attached by gently tugging on it to ensure that it does not come loose.

At step 1310, the user initiates the food flow from the food container to the feeding device and begins feeding the user (e.g., a child, a patient, or an aged person) via the feeding device. This step involves applying pressure to the food container, either by squeezing or pressing, to expel the food through the graduated connector and onto the feeding surface of the feeding device. The design of the graduated connector allows that the food flows smoothly and consistently, regardless of the food's viscosity. For example, a thicker food like yogurt may require more pressure to flow, while a liquid food like juice may flow more freely. The user can monitor the flow of food, adjusting the pressure as needed to control the feeding pace. This step also involves feeding the user in a manner that is safe and comfortable, allowing the feeding device to deliver the appropriate amount of food with each spoonful. The user (Feeding Assistant) may pause the feeding session, if necessary, to allow the user (feeding user-a child or physically inhibited adult) to swallow or take a break, and then resume feeding when ready.

At step 1312, when the feeding session is completed, the food container is removed from the graduated connector. Once the user has been fed the desired amount of food, the process concludes with detaching the food container from the graduated connector. This step typically involves reversing the attachment mechanism used in step 1308, such as rotating the container in the opposite direction to unscrew it or applying pressure to release a snap-fit connection. After detaching the food container, the feeding device and graduated connector can be cleaned and stored for future use.

Referring now to FIG. 13A, a flowchart 1300A of exemplary method steps that may be executed in some implementations of the present invention, is illustrated. In such implementations of the present invention, a standalone graduated connector with a plurality of connector steps on both sides may be used. Below is a detailed description of each step in the flowchart:

At step 1322, the process begins with selecting a feeding device with a feeding device end connector. This step may involve choosing a feeding device that has an appropriate end connector designed to attach securely to a connector step on the graduated connector. The choice of feeding device may also depend on the specific needs of the user (child or patient), such as the age, dietary requirements, and type of food being served. For example, a feeding device with a wide, shallow spoon may be selected for thicker foods like purees, while a narrower device may be more suitable for liquids. The end connector of the feeding device should be compatible with the graduated connector to provide a secure attachment and efficient feeding process.

At step 1324, a standalone graduated connector comprising a plurality of connector steps on two opposite sides is selected. This standalone connector is versatile, allowing for different sizes of food containers and feeding devices to be attached on either side. The graduated connector may be selected based on the range of connector steps it offers, allowing it to accommodate the specific food container and feeding device chosen for the feeding session. The flexibility provided by the multiple steps allows the caregivers to customize the connector setup to match the needs of the feeding situation.

At step 1326, a correct food container is selected, and it comprises a food container end connector. The food container is chosen based on the type and quantity of food it contains, allowing it to be appropriate for the feeding session. For example, a small pouch may be selected for feeding an infant, while a larger container can be used for an adult. The end connector on the food container should be compatible with any of selected connector steps on the standalone graduated connector, allowing for a secure and leak-proof attachment.

At step 1328, the caregiver identifies an appropriate connector step on one side of the graduated connector for the food container. The standalone graduated connector offers multiple steps of varying sizes, and the caregiver must select the one that best matches the size of the food container's end connector. For example, a smaller food container requires a smaller connector step, while a larger container needs a larger step. The correct identification of the connector step allows the system to function as intended without any interruptions during feeding.

At step 1330, the food container end connector is attached to the selected connector step on one side of the graduated connector. This attachment may involve threading, snap-fitting, or another suitable mechanism. The caregiver aligns the food container end connector with the chosen connector step and engages the connection by either rotating or pressing the container into place. The connector step is designed to provide a secure and stable attachment, allowing the food container to remain in place during the entire feeding process.

At step 1332, the caregiver identifies an appropriate connector step on the opposite side of the graduated connector for the feeding device. Similar to step 1328, this involves selecting the correct step based on the size and type of the feeding device's end connector. The graduated connector's design allows for a flexible setup where different sizes of feeding devices can be used.

At step 1334, the feeding device end connector is attached to the selected connector step on the opposite side of the graduated connector. The process is similar to the attachment of the food container in step 1330. The caregiver aligns the feeding device end connector with the selected step and engages the attachment mechanism, so that the feeding device is securely connected to the graduated connector.

In some embodiments, the feeding device and the food container are designed to connect to specific ends of the two sides of the graduated connector. In such configurations, the graduated connector may incorporate a one-way valve that controls the direction of food flow, allowing that food can only travel from the food container to the feeding device (unidirectional food flow). The one-way valve prevents backflow or leakage, maintaining a clean and efficient feeding process. As a result, it may require that the feeding device and the food container are connected to their respective designated sides of the graduated connector. The food container must be attached to the side of the graduated connector that allows the food to pass through the one-way valve in the correct direction, while the feeding device should be connected to the opposite side, where the food is dispensed to the caregiver. Failure to connect the components to the correct sides may result in improper food flow or blockages, disrupting the feeding process and potentially causing inconvenience or mess.

At step 1336, the caregiver initiates the food flow from the food container to the feeding device and begins feeding the user (a child or a physically inhibited adult). This step involves applying pressure to the food container to push the food through the graduated connector and into the feeding device. The design of the graduated connector allows the food to flow smoothly, regardless of its viscosity. The caregiver monitors the flow, adjusting as necessary to maintain a consistent feeding pace.

At step 1338, the feeding session is completed, and the food container and feeding device are removed from the standalone graduated connector. This step involves reversing the attachment process used in steps 1330 and 1334, such as unscrewing or releasing the snap-fit mechanisms. The caregiver carefully detaches both the food container and the feeding device to avoid spills or messes. After detaching, the components can be cleaned and stored for future use, so that the feeding system remains in good condition and ready for the next feeding session.

Referring now to FIG. 14A, a cross-sectional view of an exemplary graduated connector 1450A is illustrated. The graduated connector 1450A is designed to accommodate varying sizes of food containers and feeding devices. FIG. 14A illustrates the internal structure of the exemplary graduated connector, highlighting various connector steps on both sides of the graduated connector and the corresponding food flow paths.

On the first side of the graduated connector 1450A, there are three exemplary connector steps 1452A, 1452B, and 1452C. These steps are designed to accommodate food containers of different sizes, with each step providing a secure connection point for a food container end connector of a corresponding size. The graduated design allows food containers with varying connector dimensions to be attached to the appropriate step, providing flexibility and adaptability for different feeding scenarios.

Similarly, the opposite side of the graduated connector 1450A includes three other exemplary connector steps 1454A, 1454B, and 1454C. These steps are intended for attaching feeding devices of different sizes. The graduated nature of these steps allows feeding devices with various end connector sizes to be securely attached, so that the feeding apparatus can be customized to suit the specific needs of the caregivers and the type of viscous food being dispensed.

FIG. 14A also shows a plurality of food flow paths within the graduated connector 1450A, represented by arrows. These arrows illustrate how the viscous food moves through the graduated connector 1450A from the food container to the feeding device. The flow paths are designed to allow the food to move smoothly and efficiently through the graduated connector 1450A, regardless of which connector steps are being used. The internal channels within the graduated connector 1450A may be configured to guide the food through the appropriate paths, preventing any blockages or disruptions in the flow.

Referring now to FIG. 14B, a cross-sectional view of an exemplary graduated connector 1450B showcases internal construction that allows for the creation of various connector steps using a series of joint points 1401 and multiple layers of connector step pipes 1402. The cross-sectional view emphasizes flexibility and functionality, enabling the graduated connector to accommodate multiple sizes of food containers and feeding devices while maintaining an unobstructed flow of viscous food.

The graduated connector 1450B is composed of multiple layers of connector step pipes 1402, which are strategically joined together at several joint points 1401. These joint points are distributed at random positions between the layers of connector step pipes, a design choice that provides the joint points that do not interfere with or restrict the flow of food through the graduated connector 1450B. The arrows in FIG. 14B represent various food-flow paths, illustrating how viscous food moves seamlessly through the graduated connector 1450B from the food container to the feeding device.

The randomness in the placement of joint points 1401 prevents any potential blockage or constriction in the food-flow paths (formed between multiple connector steps), thereby maintaining a smooth and continuous flow of viscous food through the graduated connector 1450B. The layers of connector step pipes 1402 are designed to form distinct connector steps on either side of the graduated connector 1450B. These connector steps allow for the attachment of different sizes of food containers and feeding devices.

In the preceding sections, detailed descriptions of examples and methods of the disclosure have been described. The description of both preferred and alternative examples though thorough, are exemplary only, and it is understood that to those skilled in the art that variations, modifications, and alterations may be apparent. It is therefore to be understood that the examples do not limit the broadness of the aspects of the underlying disclosure as defined by the claims.

CONCLUSION

A number of embodiments of the present disclosure have been described. While this specification contains many specific implementation details, they should not be construed as limitations on the scope of any disclosures or of what may be claimed, but rather as descriptions of features specific to particular embodiments of the present disclosure. While embodiments of the present disclosure are described herein by way of example using several illustrative drawings, those skilled in the art will recognize the present disclosure is not limited to the embodiments or drawings described. It should be understood the drawings and the detailed description thereto are not intended to limit the present disclosure to the form disclosed, but to the contrary, the present disclosure is to cover all modifications, equivalents and alternatives falling within the spirit and scope of embodiments of the present disclosure as defined by the appended claims.

For example, the present invention may include an apparatus for feeding a person viscous food and methods of use of the apparatus. The apparatus may include a food container with a food storage portion, which may be a compressible food storage container, containing a viscous food and a first connector on an open end of the food storage portion. The food storage portion may be compressible; and a feeding device according to the present invention may include a feeding surface and a second connector removably attachable to the first connector.

Implementations may include one or more of the following features. The apparatus where the food container is configured such that, when the second connector is attached to the first connector, application of compressive pressure on the food storage portion expels the viscous food through the first connector and second connector onto the feeding surface of the feeding device. The food container is configured such that the compressive pressure can be applied by a person to an exterior surface of the food storage portion. The feeding device includes a feeding surface including a spoon shaped area. The first connector includes a one-way valve flow to impede the flow of viscous food through the first connector. The one-way valve may include a silicon valve. The first connector includes two one-way valves. The two one-way valves form a sealing area in the first connector. The apparatus may include a cap removably attachable to the first connector, for closing the food container when disconnected from the feeding device. The food container may include a syringe and a food channel; and the food container may be configured such that, when a second connector is attached to the first connector, application of pressure on the food storage portion expels viscous food through the first connector and second connector through the food channel in the feeding device, and onto the feeding surface of the feeding device.

In some embodiments, a food channel may be in fluid communication with a one way valve, such as, for example, a reed valve. Pressure applied to a compressible food storage portion, causes viscous food to apply sufficient pressure on the reed valve to open the reed valve and allow the viscous food to pass through the reed valve out onto the feeding surface. When pressure is released from the food storage portion, the reed valve closes. The apparatus may include: multiple interchangeable feeding devices.

One general aspect includes a method for feeding a person. The method includes removably connecting a food container containing viscous food to a feeding device; expelling an amount of the viscous food from the food container, where at least a portion of the amount of expelled viscous food flows onto a feeding surface of the feeding device; and providing the portion of the viscous food on the feeding surface of the feeding device to the person.

Implementations may include one or more of the following features. The method may include: applying compressive force to an exterior surface of a food storage portion of the food container, where the expelling of the amount of the viscous food contained in the food container is in response to the compressive force. A connector on an end of the food container connected to the feeding device includes a one-way valve and the amount of the viscous food is expelled through the one-way valve. The method may include: disconnecting the food container containing the viscous food from the feeding device and/or closing the one-way valve following disconnecting the food container from the feeding device.

In some embodiments, the method may include: removably attaching a cap to the connector on the end of the food container after closing the one-way valve. At least a portion of the second amount of expelled viscous food may flow onto the feeding surface of the feeding device.
