Description

TECHNICAL FIELD

The subject matter described herein relates to a mixing funnel to encourage thorough mixing of carbonated water and an additive.

BACKGROUND

Conventional beverage dispensing devices operate to carbonate and/or augment water. Some devices may mix carbonated water and an additive, such as flavoring or vitamins, together in a machine and then dispense the resulting mixture into a receptacle. Unless the devices are thoroughly cleaned, this method can result in contamination occurring over time. Other devices rely on crushing, puncturing, and/or generally compromising additive containers in order to access the additives retained within the containers. These methods of breaching flavoring containers can result in splatter and mess, which, if not thoroughly cleaned, can result in similar contamination.

Still other devices rely on carbonating water within a specialized container to be attached to the device, and from which the resulting beverage is served. The container can be pre-filled with water and/or an additive, and then it can be secured to the devices and pressurized within the container and used to serve the resulting beverage. These devices, however, can create excess plastic waste, as specially adapted bottles must be produced to interface with the device. In addition, these devices can only produce a single beverage within the pressurized container.

Accordingly, there remains a need for improved methods and devices for carbonating and dispensing mixed beverages.

SUMMARY

This disclosure relates to mixing additives for a carbonated beverage.

An example embodiment of the subject matter described herein is a beverage device with the following features. A housing can have a first outlet configured to emit a primary fluid and at least one secondary outlet configured to emit an additive to be mixed with the primary fluid. A funnel can be arranged on the housing to receive the primary fluid through a funnel inlet.

In some embodiments, at least one secondary outlet and a second secondary outlet can be configured to emit a first additive and a second additive respectively. The funnel can be arranged to receive the first additive in a first fluid passage and the second additive in a second fluid passage respectively. Each passage can be defined by the funnel.

In some embodiments, the funnel can include a partition configured to direct the primary fluid along first and second flow passages. The partition can include a fluid outlet path configured to direct the primary fluid from the first and second flow passages to a funnel outlet. The funnel itself can be arranged on the housing to receive the additive at a location adjacent to the funnel inlet such that the additive flows with the primary fluid along at least one of the first and second flow passages and through the fluid outlet passage to the funnel outlet.

In some embodiments, the mixing funnel for mixing fluids includes a tray. The tray can have a back wall with a fluid inlet arranged to receive a primary fluid flow. A bottom surface of the tray can extend from the back wall towards the front wall and can have first and second fluid passages formed such that primary fluid flow from the fluid inlet is divided to flow along the first and second fluid passages. The first and second fluid passages can be sloped downward from the funnel inlet to a mixing area and can direct the primary fluid flow to a mixing area adjacent the front wall of the tray. A fluid outlet passage can extend from the mixing area to the funnel outlet. For example, fluid outlet passage can be sloped downward from the mixing area to the funnel outlet. Such an outlet for fluid can be arranged to receive the primary fluid flow from the mixing area.

In some embodiments, the fluid inlet and the outlet are positioned adjacent the back wall. In addition, at least one wicking rib can extend between the inlet and the outlet along an outside of the tray. In some embodiments, a handle can be formed on the front wall of the tray.

A partition can be located between the first and second fluid passages and configured to direct the primary fluid flow from fluid inlet into the first and second fluid passages. In some embodiments, the partition can define an exit flow path extending to the fluid outlet. The partition can project upward from the bottom surface and is substantially U-shaped. The bottom surface can be sloped downward from the back wall towards a front wall of the tray.

A variety of features can be included to mitigate any splashing that may occur during operation. For example, ribs can extend from an upper edge of the tray towards an interior of the mixing funnel. Alternatively or in addition, a removable cover can be disposed over the tray. In such embodiments, the cover can include ports to allow for fluid ingress. In some embodiments, an interior surface of the tray can be hydrophilic.

DETAILED DESCRIPTION

Certain embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.

Further, in the present disclosure, like-named components of the embodiments generally have similar features, and thus within a particular embodiment each feature of each like-named component is not necessarily fully elaborated upon. Additionally, to the extent that linear or circular dimensions are used in the description of the disclosed systems, devices, and methods, such dimensions are not intended to limit the types of shapes that can be used in conjunction with such systems, devices, and methods. A person skilled in the art will recognize that an equivalent to such linear and circular dimensions can easily be determined for any geometric shape. Sizes and shapes of the systems and devices, and the components thereof, can depend at least on the anatomy of the subject in which the systems and devices will be used, the size and shape of components with which the systems and devices will be used, and the methods and procedures in which the systems and devices will be used.

In general, a mixing funnel for mixing a carbonated fluid with an additive is described herein. The mixing funnel can be configured for use in a carbonated beverage system and it can be arranged to receive a primary fluid and at least one additive. The primary fluid can be any fluid, such as water, and it may or may not be a carbonated fluid. In the context of this disclosure, “carbonated fluid” encompasses fluids with any gas, such as nitrogen and/or carbon dioxide, entrained in the fluid such that the fluid has an effervescent quality. While primarily described as using carbonated fluid, non-carbonated fluids can be used as well, for example, water or alcohol can be used without departing from this disclosure. In some embodiments, the mixing funnel for mixing fluids can be in the form of a tray. The tray can have a fluid inlet arranged to receive the primary fluid flow, and it can include first and second fluid passages such that primary fluid flow from the fluid inlet is divided to flow along the first and second fluid passages. The tray can also be positioned to receive one or more additives in the first and second fluid passages, such that the additive(s) flow into the primary fluid flow. The first and second fluid passages can be sloped downward from the fluid inlet to a mixing area, which can be configured to aid in mixing the additive(s) with the primary fluid. A fluid outlet passage can extend from the mixing area to a funnel outlet, whereby the combined primary fluid and an additive is emitted. The use of a single outlet nozzle can allow for drinking vessels with narrow openings to receive the resulting beverage.

FIGS. 1-2 illustrate a beverage dispensing system 10 according to one embodiment. A person skilled in the art will appreciate that the mixing funnel can be used with any beverage dispensing system, and the illustrated system is merely one example of such a system. The beverage dispensing system 10 can be used to create and dispense customized beverages for a user, based on desired characteristics of the beverage. The illustrated beverage dispensing system 10 generally includes a housing 12 having a fluid reservoir 14 and a carbonation assembly 16. In the illustrated system 10, a mixing funnel 18 is included for receiving one or more additives from containers 20, as well as the primary fluid to be used in the creation of beverages. The additive containers 20 can include one or more additives (e.g., a flavorant, a vitamin, a food dye, etc.) to be included in a created beverage as desired. In some embodiments, two additive containers 20 can be used. Each additive container can include its own outlet arranged to emit additives into the mixing funnel 18. A person skilled in the art will appreciate that the mixing funnel disclosed herein can be used in any beverage dispensing system, including those that lack an additive container. Other beverage dispensing systems include, by way of non-limiting example, coffee, tea, beer, juice, and similar beverage-making apparatus.

During a beverage dispensing process, a user can actuate inputs located at a user interface 22 in order to select specific characteristics of the desired beverage, such as fluid volume and carbonation level. If the user selects inputs to indicate that the beverage is carbonated, water can be fed from the fluid reservoir 14 and into the carbonation assembly 16, and carbon-dioxide can be fed from a canister 24 and into the carbonation assembly 16 to produce carbonated water. The beverage can be dispensed into a container, such as a flask 26, from an outlet of the funnel 18.

Examples of beverage dispensing systems compatible with the carbonation mixing chamber provided herein may be found in U.S. patent application Ser. No. 17/989,640, entitled “ADDITIVE CONTAINERS FOR USE WITH BEVERAGE DISPENSERS” filed on Nov. 17, 2022, and U.S. patent application Ser. No. 17/744,459, entitled “FLAVORED BEVERAGE CARBONATION SYSTEM” filed on May 13, 2022, the contents of both of which are hereby incorporated by reference in their entirety.

The mixing funnel 18 is shown in more detail in FIG. 3A and FIG. 3B. The illustrated funnel 18 includes a tray 300 and a handle 302 extending along a front outer portion of the tray 300. The tray 300 can have a variety of configurations, but generally includes a front wall 304, a back wall 308, and opposed side walls 306. Extending between the walls is a tray bottom 320. The tray bottom can define features to aid in fluid flow and mixing as will be discussed below. The handle 302 can define all or a portion of the front wall 304 of a tray 300. In some embodiments, the handle 302 can project radially outward from the front wall 304, for example, along an entirety of the front wall 304. In some embodiments, the handle 304 can extend laterally past side walls 306 of the tray 300. In some embodiments, the front of the tray 300 and/or the handle 302 can have a profile matching an outer surface of the beverage dispensing system 10. In some embodiments, the handle 302 can define a shoulder 309 (FIG. 3B) along its forward-most edge to provide an improved grip for the user.

As indicated above, the tray 300 can define several areas to direct fluid flow. In the illustrated embodiment, a fluid inlet 310 can be arranged in the back wall 308 of the tray 300 to receive a primary fluid flow 312, for example, water or carbonated water. While the fluid inlet 310 is shown formed in the back wall 308, in other embodiments the fluid inlet 310 can be adjacent the back wall or formed at other locations in the tray, including simply positioned above the tray. Regardless of location, the inlet 310 can be shaped to receive, retain, or otherwise engage with an outlet of the beverage dispensing system 10. For example, in embodiments where the beverage dispensing system 10 emits the primary fluid from a tubular conduit, the tray inlet 310 can define a partially circular or hemi-cylindrical profile to engage with the tubular conduit. As further shown in FIG. 3A, in order to aid in fluid flow through the inlet 310, the inlet 310 can taper radially outward from the inlet toward the tray center.

Following the primary fluid flow 312, after the primary fluid enters the inlet 310, the primary fluid flow 312 can impact a partition 316 dividing and directing the primary fluid flow 312 into a first flow passage 318a and a second flow passage 318b with the partition 316 positioned between them. In some embodiments, the partition 316 projects upward from a bottom surface 320 of the tray 300 and can be U-shaped. However, other partition shapes and arrangements, such as a V-shape, can be used without departing from this disclosure. Further, while a single partition is shown to divide the tray into two flow passages 318a, 318b, the use of a partition and/or the number of partitions can vary depending on the number of additive containers to be used in the beverage dispensing system. For example, a system that receives only a single additive container may have a tray that lacks a partition altogether, whereas a system that receives three additive containers may have two partitions for form three flow passages.

In the illustrated embodiment, each of the flow passages is defined by the partition 316, a bottom surface 320 of the tray 300, and side walls 306 of the tray 300. The portion of bottom surface 320 defining the flow passages 318a, 318b can be slanted or sloped downward from the inlet 310 at the back to the front of the tray to direct the primary fluid flow 312 towards a mixing area 322 located near a front wall 304 of the tray (e.g., adjacent or nearer the front wall 304 than the back wall 308). Further, the flow passages 318a, 318b can be tapered inward from the back to the front to direct fluid into the mixing area, discussed below. Each of the fluid passages 318a, 318b can be positioned below outlets of the additive containers 20. That is, the additives 324 can be received by the tray 300 at a first receiving area 326a and/or a second receiving area 326b. In operation, the additives can be delivered into either flow passage 318a, 318b for a duration of time, and the primary fluid flow 312 can flow through the passages 318a, 318b during or after the duration of time. That is, the primary fluid is used to carry away an entirety (e.g., most of) the additive 324 to help keep the tray 300 clean.

Several features can be used to reduce the risk of fluids splashing out or the tray 300. In some embodiments, the primary fluid flow 312 is feed into the funnel 18 at a low pressure or gravity only, and the additives 324 are fed into the funnel 18 with low pressure or gravity only. However, in some instances, a hard dispense can occur. Such an event can occur when pressure upstream of the inlet 310 is not vented down to atmospheric pressure prior to dispensing the primary fluid flow 312. This can result in the high pressure primary fluid flow 312 potentially causing splashing. Thus, retaining ribs 328 can extend from the side walls 306 and/or back wall 308 towards an interior of the tray 300 to overhang the fluid passages 318a, 318b thereby preventing (or reducing the likelihood of) fluid from flowing above the upper boundary of the tray 300. Alternatively or in addition, the ribs 328 can perform a similar function regarding the additives 324, for example, with embodiments that emit additives 324 at high enough pressure to result in splashing. In such embodiments, gaps in the retaining ribs 328 can be included as to allow for fluid ingress into the tray, such as around the inlet 310 or around the target areas 326a, 326b that receive the additives 324 from the additive containers 20 (FIG. 1) located above the funnel 18.

The fluid passages 318a, 318b can combine once again at the mixing area 322. The mixing area 322 can be defined, at least in part, by the bottom surface 320 of the tray 300 sloping downward towards an outlet nozzle 330. The outlets of the fluid passages 318a, 318b and the mixing area 322 are arranged to swirl the mixture of primary fluid 312 and additive 324 within the mixing area 322. For example, in some embodiments, a slope of the mixing area 322 is in an opposite direction to a slope of the fluid passages 318a, 318b. The change in direction can encourage swirling of the fluid emerging from the fluid passages 318a, 318b. Alternatively or in addition, the mixing area 322 can have a larger surface area than the fluid passages 318a, 318b. Such a change in surface area can also induce swirling. The swirling is sufficient to effectively mix the additive 324 and the primary fluid 312, but is preferably gentle enough to allow carbonation to be substantially retained (e.g. partially or fully retained) within the resulting mixture 332.

In addition, in some embodiments, at least an inner surface of the tray 300 can be hydrophilic. Such a surface can be achieved with a coating, texture, or material of which the tray is composed. The hydrophilic surface can help retain carbonation within the primary fluid flow 312 and/or the resulting mixture 332.

Following the fluid flow from the mixing area 322, the resulting mixture 332 flows towards the outlet nozzle 330 through an exit flow passage 334 defined by at least the partition 316 and the bottom surface 320. In particular, the exit flow passage 334 can be formed in the middle of the u-shaped partition 316 and it can slope downward from the front toward the back of the tray. In some embodiments, the outlet nozzle 330 can be nearer the back wall 308 than the front wall 304. In such embodiments, at least a portion of the bottom surface 320 can be sloped downward from the front wall 304 towards the back wall of the tray 300. That is, a fluid outlet passage 334 is sloped downward from the mixing area 322 to the funnel outlet nozzle 330. As the fluid transitions from the bottom surface into the outlet nozzle 330, the bottom surface can define a smooth transition from the slope directing the resulting mixture 332 towards the outlet nozzle 330. For example, a radius 336 of the transition can be great enough to reduce the likelihood of cavitation, separation, turbulence, or other phenomena that can result in carbonation being released from the mixture. Similarly, all slopes described within this disclosure can be shallow enough to substantially retain (e.g. partially or fully retained) carbonation within the resulting mixture and primary fluid flow throughout the operations described herein. For example, in some embodiments, the slopes can be between 5° and 15°.

The outlet nozzle 330 itself can project downward from the bottom surface 320 to direct fluid into a beverage container, such as the flask 26 (FIG. 1). The nozzle 330, while illustrated as having a circular cross section, can have other cross-sectional shapes, such as an oval or square cross-sectional shape. In some embodiments, one or more support struts 338 can extend across the outlet nozzle 330. These support struts 338 can help provide structural rigidity to the outlet as well as act to straighten the flow of the resulting mixture exiting the funnel 18 through the nozzle. While the present illustrations show three support struts 338, greater or fewer support struts can be used without departing from this disclosure. The nozzle can be of sufficient length to direct the resulting fluid in a substantially downward direction (within 45°). Alternatively or in addition, the nozzle 330 can have a cross-sectional area large enough to reduce the likelihood of vapor lock, which can release carbonation from the resulting mixture. Alternatively or in addition, the nozzle 330 can have a cross-sectional area similar to that of an outlet 901 of the beverage machine 10 that dispenses the primary liquid (FIG. 9). Alternatively or in addition, the nozzle size can range from 6.5 millimeters to 10 millimeters. In some embodiments, the transition radius 336, nozzle 330 cross section, and nozzle 330 length are all configured to achieve a fill level on the funnel in a front window as a visual show for a user when the funnel 18 is made of a semi-transparent or fully transparent plastic.

As previously discussed, the nozzle directs a resulting mixture downward, for example, into a drink container. To the extent there are any leaks, the tray 300 can include additional features to direct the leaks into a drink container. FIG. 4 illustrates such a feature. In FIG. 4, wicking ribs 402 extend along an outer surface (back wall 308 and bottom 320) of the tray 300 between the inlet 310 and the nozzle 330. The wicking ribs 402 define smooth surfaces that follow the contours of the tray 300. Surface tension allows any fluid overflow to follow the wicking ribs 402 from the inlet 310 to the outlet nozzle 330 in the event of stray droplets leaking from the inlet 310 to the outside of the tray 300. While two wicking ribs 402 are shown, greater or fewer wicking ribs 402 can be used, for example a single wicking rib 402 or three wicking ribs 402 can be used.

While the wicking ribs 402 can be used to mitigate leaks from the tray, other features can be used to better retain fluid within the tray. Such a feature is illustrated in FIG. 5. In the illustrated embodiment, a cover 500 is disposed over the tray 300. In such embodiments, the cover 500 can be attached to the tray with a one or more hinges 506. Alternatively or in addition, the cover 500 can be attached to the tray by snap connections. In some embodiments, the cover can be a removable cover. Removability can improve cleanability of the funnel 18. In some embodiments, tabs 508 are included for a user to manipulate (for example, remove or open) the cover 500. In some embodiments, the cover 500 can be used in lieu of or in addition to the ribs 328 (FIG. 3A).

In embodiments that include the cover 500, the cover can define one or more ports. For example, the cover 500 can define a primary port 502 for providing access to the inlet 310 such that the cover 500 does not block the inlet 310. Alternatively or in addition, the cover can define one or more additive ports 504 for allowing additive to be delivered into the tray. The additive ports 504 can be located above the first flow passage 318a and the second flow passage 318b (FIG. 3A). Other port locations are possible without departing from this disclosure, for example, in some embodiments, a port can be located over the mixing area 322.

In another example of fluid retaining features, as shown in FIG. 6, a splash hood 650 can be integrated into the tray 600. The tray 600 is substantially similar to the embodiments previously described with the exception of any differences described herein. The splash hood 650 can extend from the front wall 604 of the tray 600 towards a back wall 608 of the tray 600. In some embodiments, the splash hood 650 extends between both side walls 606 of the tray 600. The splash hood 650 can extend, for example, 25% to 50% the length of the tray 600. In some embodiments, the splash hood 650 can define a generally convex structure with a rounded or tapered profile. For example, a center part of the splash hood 650 can have a greater length than edges of the splash hood 650 adjacent to the side walls 606. Such a shape reduces the likelihood of interfering with the emitted additives into the first flow passage and the second flow passage (not shown in present view, but substantially similar to flow passages 318a and 318b previously described). In some embodiments, the splash hood 650 can extend above the tray 600. For example, the splash hood 650 can have a dome-like curve extending above a plane defined by a top of the tray 600. Features described in various embodiments can be combined with one another without departing from this disclosure, for example, an embodiment can include the splash hood 650 and the retaining ribs 402 (FIG. 4).

Alternatively or in addition, draining wings 750, as shown in FIG. 7, can be integrated into the tray 700. The tray 700 is substantially similar to the embodiments previously described with the exception of any differences described herein. The wings extend along the handle 704 past the side walls 706 of the tray 700. The wings 750 act to extend a height of the tray 700 in areas where splashing is likely to occur, for example, during a hard dispense. Each wing includes a wing wall 754 to help retain liquid in such an event. Each wing 750 can define a ramp 752 directing any liquid received during splashing back into the tray 700. In the illustrated embodiment, the wings 750 have a substantially triangular shape; however, other shapes can be used without departing from this disclosure. Features described in various embodiments can be combined with one another without departing from this disclosure, for example, an embodiment can include the wings 750 and the retaining ribs 402 (FIG. 4).

The tray 300, 600 can be made of a variety of materials, for example, plastic, metal, or any other material suitable for food contact. In some embodiments, the funnel can be made of multiple materials, for example, the cover 500 can be made of plastic while the tray (300, 600) can be made of metal.

The funnel itself can include several features that are arranged to interface with the beverage dispensing system 10. For example, depressions 510 as shown in FIG. 5 can be include that are arranged to mate with one or more corresponding protrusions 802 of the beverage device 10 shown in FIG. 8. In some embodiments, the protrusions 802 can be spring loaded, for example, by a metallic coil spring or by a cantilevered plastic spring 902 as shown in FIG. 9. The beverage device 10 defines a receptacle 800 configured to receive and retain the funnel 18. For example, in some embodiments, the receptacle 800 defines rails 804 upon which the funnel 18 can rest. In operation, the funnel 18 can slide across the rails 804 during insertion and removal. Once installed, the rails 804 can at least partially vertically support the funnel 18. Alternatively or in addition, the funnel can include a protrusion arranged to impact a microswitch 904 shown in FIG. 9 coupled to a controller of the beverage dispensing system 10 that can be used to determine a presence of the funnel. In some embodiments, such a microswitch can be coupled to the spring loaded protrusion 802.

While this disclosure contains many specific embodiment details, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of features specific to particular embodiments. Certain features that are described in this disclosure in the context of separate embodiments can also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a subcombination or variation of a subcombination.

Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. Moreover, the separation of various system components in the embodiments described above should not be understood as requiring such separation in all embodiments, and it should be understood that the described components and systems can generally be integrated together in a single product or packaged into multiple products.

Thus, particular embodiments of the subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results.
