20210077648
This patent document relates to scented material compositions and articles for use with food and beverage, including methods and equipment for their manufacture, and, in particular, scented articles for a scented bottle cap system having a scented attachment for enhancing a user's sense of smell and/or taste.
The nasal cavity has specialized sensory cells that mediate olfaction. The main olfactory system of humans and animals detects volatile chemicals, and the accessory olfactory system detects fluid-phase chemicals. Olfaction like taste is a form of chemoreception. The chemicals that activate the olfactory system, generally at very low concentrations, are called odorants. Accordingly, there is a commonality between the perception of smell and the perception of taste. In fact, in certain instances, the sense of smell may supplement and/or otherwise enhance the sense of taste. For instance, it is well known that maladies affecting the sense of smell adversely affect the sense of taste. As taste plays an important role in ones motivation for consuming a food or drink article, there is an interest in the art for agents that enhance the perception of taste of food and drink articles. The present disclosure addresses these and other such needs.
Aspects of the disclosure include an attachment for providing a scent to a container. In certain instances, the scented attachment is configured for being associated with a container, such as a drink or a food storage container. The scented attachment may be associated with the container in any suitable manner.

Scented Attachments, Systems and Methods of Use
As can be seen with respect to
For instance, in certain instances, a scent may be a chemical agent that stimulates a chemoreceptor of the olfactory system of the subject or otherwise stimulates sense of smell and/or taste of a subject. For example, in certain instances, a scent may be a volatile compound or odorant, such as a fragrant or other essential oil. Where the scent is a fragrant oil, it may be a food derived oil such as a citrus oil, a mint oil, anise oil, cardamom oil, cinnamon oil, clove oil, coriander oil, eucalyptus oil, fennel oil, lemongrass oil, and/or a nutmeg oil, and the like. The scent may be a citrus oil such as a lemon oil, a lime oil, a neroli oil, and/or an orange oil, and the like. In certain instances, scent comprises a mint oil such as a peppermint oil and/or spearmint oil, and the like.
The scented essential oil may be incorporated within the attachment in any suitable manner. For instance, the attachment may include a matrix within which the essential oil may be incorporated. The matrix may include a liquid or a gel, which may include the scent. The liquid or gel may be associated with the material employed to fabricate the attachment. For example, the attachment may be constructed in any suitable manner and may be fabricated from any suitable material. In certain instances, a suitable material may be one or more of an elastic material, a foamed or vulcanized rubber, neoprene, polyurethane, nylon, lycra, plastic, silicone, and/or a silicone containing material. Hence, the material from which the attachment is produced may be fabricated into a ring or sheet and compression or liquid injection molded into a protective device in accordance with some embodiments of the disclosure.
For instance, the body of the attachment may be fabricated using compression molding, during which process an element containing an essential oil is added thereto either during or after the molding process. Additionally, a colorant or other chemical additive may be added to the sheet blanks, which become the compression molded end product, for instance, to color and/or to aid in the release of the product from the mold. In certain instances, the attachment is made from a single piece of shaped or otherwise molded material and may include a cavity into which a scented material, e.g., a gel or substrate containing an essential oil associated therewith is injected or otherwise inserted into the lumen of the scented attachment. The main body of the attachment may comprise elastic properties, such that the attachment can deform to receive a portion of a container, e.g., a neck thereof, and then reform to its original configuration automatically, that is without the need for external manipulation. In certain instances, the attachment may include a main body that is pre-formed into a substrate onto one surface of which a gel or other matrix containing a scented agent, e.g., an essential oil, is added; and to an opposing surface, a suitable attachment mechanism, e.g., an adhesive, is added. One or more removable covers may be added to cover one or more of the scented surface and/or the attachment surface.
The attachment can be made into any desired shape such as a tube, a square or rectangular box, a triangular, pyramidal or circular shape, or the like. And thus the attachment may be configured for fitting around suitable container, such as a round, circular, triangular, square, rectangular, cube shaped container, or the like, and may be of regular or irregular dimensions, so as to fit a variety of bottles, jars, and the like. In certain instances, a scented attachment such as attachment 10 shown in
Accordingly, the attachment 10 may be of any suitable size and shape, but is typically of a size and shape so as to be non-obstructively associated with the container 20. The container 20 may be any container such as a container for storing a beverage or other food article. The container 20 may be of any size or any shape, but is typically of a size and a shape suitable for containing a drink or food product, such as a drink or food product that is meant to be readily consumed by a subject. For instance, the container 20 may be a plastic or glass container, a metal or metal alloy container, or the like. If the container 20 is made of glass, the glass may be of any suitable type of glass, such as silicon dioxide, sodalime glass, pyrex, lead crystal, and the like. If the container 20 is made of metal, the metal may be of any suitable type of metal, such as aluminum, steel (e.g., stainless steel), tin, and the like. The container 20 for use in accordance with various embodiments of the scented attachment disclosed herein may also include alloys of any suitable metals. The container 20 may also be a plastic container, such as a TUPPERWARE® or RUBBERMAID® or GLAD® container.
The container 20 may contain any material, such as a solid, liquid, or gas. In certain instances, the container 20 is a fluid container that contains a liquid. The liquid within the container may be any form of liquid. In certain embodiments, the liquid is a liquid that is meant to be imbibed. For instance, in certain embodiments, the liquid is a liquid such as, water, soda, a liquid nutrient, a juice, an electrolyte, a sports drink, an alcoholic beverage, and the like. In certain embodiments, the container 20 is a solid object container, for instance, a food container that contains a solid food. For example, the attachment may be configured for being associated with a bottle, a can, a thermos, a camel back container, a canteen, or other such drinking container. In certain instances, the container may be a food container, such as a container for the storage of a food.
The attachment 10 may be associated with the container 20 in any suitable manner. In some instances, the attachment 10 is of a size or shape so as to fit around a circumference of the container 20. Thus, the attachment 10 may be a ring, sleeve, wrap, or the like that has been fabricated in such a manner so as to include a scent therein. For instance, in certain instances, the attachment 10 may be a ring that may be flat or tubular and may include an opening through which a container may be inserted. Accordingly, in certain instances, the ring attachment may be of a size and a shape so as to fit around a portion, e.g., the neck, of a drinking container. The ring, therefore, may have a diameter such that it can slip onto and/or around the neck of a bottle, but not slide down the length of the bottle.
As described above, the attachment 10 may be made of any suitable material, but in certain instances, it is made of a material that is capable of stretching, and thus the diameter of the ring may be configured for moving from a first, smaller diameter to a second, larger diameter when stretched, and/or for returning from the second stretched diameter toward the first, non-stretched diameter in the absence of a suitable stretching force. In a manner such as this the attachment 10 such as the ring embodiments may be configured for fitting snuggly around a portion of the container 20, e.g., the neck, the middle, and/or bottom of the container.
As illustrated in
In certain instances of the attachment 10 structured as a ring, as shown in
For instance, as seen with reference to
In certain instances, as with reference to
In some aspects in accordance with the present technology, the scented articles, apparatuses and systems are directed to a protective sleeve system. In certain embodiments, for example, the protective sleeve system is configured for both holding and protecting a held container. Accordingly, in certain embodiments, the protective sleeve system includes a protective sleeve (such as described above), which includes a tubular body, configured for holding a container, and at least a first opening, adapted for receiving the container, and in addition to the protective sleeve, the protective sleeve system may include a suitable container, such as those described above, for instance, a bottle, can, or other food storage element that is adapted to be fit and/or held within the protective sleeve.
For instance, in certain instances, the scented attachment may be included in a system that includes a suitable container, such as a glass or plastic bottle. For example, the container may be a water or sports drink bottle, or the like. The attachment may be previously associated with the bottle or may be a separate element that is meant to be attached to the container by the user of the container prior to use. The attachment may be a substrate having a scented surface having a cover thereon and may include an adhesive surface additionally having a cover thereon. The cover over the adhesive may be removed and the substrate associated with the container by the user. The cover covering the scented surface may then be removed by the user prior to consuming the drink or food item therein. In an alternative embodiment, the attachment may be a ring that is configured for being slid over an end of the container and associated thereby with the container, for instance, a neck of the container, e.g., by a user.

Scented Bottle Cap Systems and Methods of Fabrication and Use
In some aspects of the scented attachment in accordance with embodiments of the present technology, a scented bottle cap system includes a scented ring attachable to a bottle, e.g., disposed around the neck of the bottle, and a cap removably attachable to the bottle and configured to enclose the scented ring in a hollow region between the cap and the bottle when the cap is securely attached to the bottle, such that the scented bottle cap system entraps a scent from the scented ring in the hollow region when the cap is securely attached to the bottle and controllably releases the scent into the proximate environment of the bottle when the cap is removably detached from the bottle. In implementations of the scented bottle cap system, for example, the scent can include one or more chemical agents in a volatile compound or aggregate that provides a pleasing odorant to the user of the scented bottle cap system that stimulates a corresponding chemoreceptor of the user's olfactory system to enhance the user's sense of smell and/or taste of a drinkable fluid in the bottle. For example, the odorous compound or aggregate can include an oil, a liquid or gel (e.g., carried in a matrix), or a resin or powder. In various embodiments, the scented ring can contain the scent by various methods, including incorporating the scent into the material of the ring, e.g., during a fabrication process to produce the ring. In some embodiments, for example, the scented ring can be fabricated using a plastic material, e.g., polyethylene, polyurethane or other example materials described herein, that is loaded with the odorous compound or aggregate that produces the scent to a desired concentration, e.g., which can be selected based on multiple variables including the type of scent (e.g., degree of pungency of a particular scent).
In the example shown in
In the example shown in
Also shown in the example embodiment of the scented ring 610 in
For example, the scent can be incorporated into the body of the scented ring 610, e.g., through the manufacturing process such as injection molding, in which the chemical agents that form the scent are embedded in the material that forms the structure of the scented ring 610. In other embodiments, for example, the scent can be produced on the scented ring 610 by providing an exterior coating to the ring body, e.g., via spray coating, printing or other techniques to coat the scented ring 610. In implementations, the scent emanates from the scented ring 610 by diffusing into the air that surrounds the scented ring 610. Generally, over time the scent would eventually diffuse to a concentration where it would be ineffective to stimulate one's olfactory senses when placed near the user, such as when the user brings the bottle neck toward his/her mouth and nose. Thus, the scented bottle cap system 600 provides a structure that controls the storage and release of the scent from the scented ring 610, thereby (i) conserving the scent for longer durations and repeated uses, and (ii) regulating the timing and concentration of emanation of the scent to the ideal moments that effectuate the user's enjoyment of the beverage in the bottle 630.
Referring back to
The bottom end of the curved wall 627W is structured such that, when the cap 620 is securely attached to the bottle 630, a portion of the bottom end contacts the collar 631 and provides a lower seal between the cap 620 and the collar 631 of the bottle 630. The cap 620 is structured to have a concentric space 629 in the interior region, which can be at least between the rim structure 625 and the location of the lower seal. In the example shown in
In some embodiments, such as the examples shown in
A compartment providing a hollow volume 940 formed in a space between the cap 620 and the bottle 630 can be configured based on the size and shapes of the structural components of the cap 620 and bottle 630. The compartment including the hollow volume 940 is configured to collect and trap the scent that emanates from the scented ring 610 when the cap 620 is closed (e.g., tightened) on the bottle 630. For example, the system 600 is configured to trap the scent when the cap 620 is closed on the bottle 630, e.g., including in-between drinks of the beverage, to create a scent burst effect when the user opens the cap and takes the next drink. As illustrated in the example embodiment shown in
In some implementations, the dimples 1111 and/or bumps 1112 are formed of a size and/or shape and arranged on the scented ring 1110 to affect the direction of the scent emanating from the scented ring 1110 to the proximate environment. For example, the motion of the bottle 630 by the user to drink the beverage can increase the rate of air flow at the scented ring 1110 and affect to the volatility of the scent at the dimples 1111 and the bumps 1112. Also, for example, the dimples 1111 can be structured as holes that pass through the ring 1110 or terminate at a hollowed chamber in the body of the ring 1110 to affect the effusive properties of the scent when the cap 620 is removed from the bottle 630. In some implementations, the dimples 1111 can be arranged on the region of the scented ring 1110 that is in contact with the cap 620 when securely attached to the bottle 630, e.g., such as arranged along the exterior anchors 612 that contact the rim structure 625. In such implementations, the scent can be trapped in the hollowed chambers and their release controlled accounting for the effusive properties of the scent through the dimples 1111 and into the outer environment, e.g., near the user's nose and mouth. In some implementations, the bumps 1112 can also be structured to affect the effusive properties of the scent to enhance the sensation of the user's olfactory system.
In some aspects of the scented attachment for containers in accordance with embodiments of the present technology, methods are disclosed for manufacturing a scented bottle cap system to fill the bottle with a fluid, e.g., beverage, to be contained within the bottle and attaching the cap and scented ring to the bottle in a single step.
The method 1300 includes a process 1320 to orient the ring-cap assembly in a non-inverted position, i.e., where the opening of the cap is facing downward, in which the scented ring is securely contained in the interior region of the cap. The method 1300 includes a process 1330 to fill the bottle with a fluid, e.g., a beverage such as water, milk, juice, sports drink, alcoholic beverage, etc. The method 1300 includes a process 1340 to securely attach the ring-cap assembly to the bottle to form a ring-cap-bottle assembly, in which the scented ring attaches to the bottle and is enclosed in a compartment formed between the interior of the cap and the exterior of the neck of the bottle, and in which the cap is detachable from the bottle and decouples from the scented ring. In implementations of the process 1340, the ring-cap assembly is attached to the bottle in a single step. For example, the method 1300 allows the ‘bottling process’ of a beverage to be performed using conventional machine- or automated-equipment in existing bottle factories to perform the processes 1320, 1330 and 1340 without significant modifications to the existing bottling process set-up and infrastructure, and thereby enable mass production of scent-enhanced beverages using a scented bottle cap system in accordance with the disclosed technology in cost-conserving manner. The ring-cap-bottle assembly forms a system that (i) contains the beverage filled in the bottle, (ii) contains and conserves the scent in the compartment, preventing its escape until a user chooses to open the cap from the bottle, and (iii) affects the emanation of the scent to stimulate the user's olfactory system and enhance the user's enjoyment of the beverage.
In some embodiments, for example, the method 1300 includes a process to attach a tamper seal (e.g., sticker) to the produced ring-cap-bottle assembly that contains the fluid, e.g., providing an indicator to a user that the fluid contained in the ring-cap-bottle assembly is unadulterated and untampered. In some implementations, for example, the tamper seal is applied at a portion or completely around the interface of the cap with the bottle. In some embodiments, for example, the method 1300 includes a process to apply one or more labels to the bottle.

Methods for Manufacturing Scented Material Compositions and Articles
Fragrance or aroma compounds have been used since antiquity to freshen air and cover odors. One early example includes incense, an aromatic material that forms a fragrant smoke when burned, which is believed to have been used by the ancient Egyptians, Babylonians, and other ancient peoples thousands of years ago. Perfumes were developed over time, having various concentrations of aromatic compounds in a solvent, such as an alcohol. For example, an eau de cologne typically has 3-8% aromatic compound(s) in solvent, whereas an eau de toilette has 5-15% aromatic compound(s) in solvent. By the middle of the twentieth century, fragrance compounds were manufactured into aerosol sprays for air freshener and deodorant products; and decades later, scented materials were developed in products like scented candles.
In humans, mammals and other living things, the olfactory system detects airborne substances, e.g., volatile chemicals, and provides the living organism with a sense of smell. Olfaction, like taste, is a form of chemoreception. Accordingly, there is a commonality between the perception of smell and the perception of taste. In certain instances, the sense of smell may supplement and/or otherwise enhance the sense of taste, and, for example, maladies affecting the sense of smell adversely affect the sense of taste.
Taste plays an important role in one's motivation for consuming food or drink. As such, food science has spent decades formulating new processed foods and drinks having agents that enhance the perception of taste of food and drink articles. However, more and more studies are showing adverse health effects for some processed foods, which can be due to additives that were used to enhance perception of taste.
Scent-based technologies, such as scented materials and articles, can be used to augment the characteristics of the material or article to affect a person's sense of smell, and thereby sense of taste. For example, a scented material or article may include a chemical agent, such as a fragrance or aroma compound, that stimulates a chemoreceptor of the olfactory system of the subject or otherwise stimulates sense of smell and/or taste of a subject.
One example of scent-based technologies includes scented articles that attach or are included as part of a drinking bottle system, like those described in this patent document, in which the scented article provides a pleasing odorant to a user that stimulates a corresponding chemoreceptor of the user's olfactory system to enhance the user's sense of smell and/or taste of a drinkable fluid in the bottle. For example, the scented article can be a lime-scented ring that attaches to the bottle around the bottle opening so that, as the user drinks the beverage within the bottle, such as water, the user experiences a lime-taste to the water from the lime scent that emanates from the scented article while drinking.
For such scented articles attachable to a drinking bottle, the final scented product should have a small size relative to the bottle and/or cap, and therefore limited surface area, while having a strong structure to prevent unintentional detachments from the bottle (e.g., which could cause choking) or unintended uses (e.g., user eating the scented article)—and yet must still provide a strong-enough scent for the user to smell while consuming the beverage. For the scented article to achieve such functionality with a small size, the fragrance composition should be loaded and preserved at a sufficient concentration in the base material to produce a robust, stable scented product suitable for applications like scented beverage container systems.
Yet, producing scented articles that have small sizes and surface areas for emanating the scent is not achievable with conventional approaches for manufacturing scented articles. This may be because low concentration scented articles can be made suitable for various applications where the size and surface area of the article is not as limiting as for the example scented attachments disclosed in this patent document, including but not limited to the scented ring 610 and/or other examples of the scented rings described herein. Existing manufacturing methods to produce scented articles use relatively low concentrations of the fragrance compound in the bulk material of the article, e.g., such as concentrations of 1% or less. For example, conventional methods may produce the scented article using a fragrance material such as a fragrance oil having a relatively low concentration of the scented compound (e.g., 5% concentration or less) that is loaded in the bulk material at loads of 10% or less with respect to the base material(s), which results in a 0.5%, or less, concentration of fragrance composition in the scented article. As such, conventional approaches for manufacturing scented articles do not address the challenge of loading high concentrations of a fragrance material in low volumes of base materials, let alone for scented articles that require robust, rigid plastics as the base material to provide the structure and shape of the article.
The challenges in manufacturing solid scented materials includes designing a stable material that has a high adsorption capacity for volatile compounds. In the design of scented material, the rigid plastic must (1) trap a sufficient amount of the scented compound in the plastic (e.g., the polymeric matrix) in order to deliver the scent and (2) control the capture of the fragrant compound as a function of time such that there is a controlled and continuous release of the scented material over a given period of time. For example, if the polymeric material (e.g., the plastic) is packed too tightly, that is not porous enough, the fragrance will not be effectively released from the material and therefore, the fragrance will not be delivered. Conversely, if the polymeric material is packed too loosely, that is too porous, then the fragrant compound will rapidly diffuse out of the plastic, resulting in an unstable scented material. Moreover, scented compounds typically exhibit properties that make them difficult to manage during synthesis and post-synthesis, such as sensitivities to oxidation, hydrolysis and heat that cause the scented compounds and/or their constituents to be affected by the presence of oxygen, water, and heat, respectively, in their production environments. Since different scented compounds provide different fragrances or aromas, their chemical constituents vary between the compounds, which adds further complexity to the compound synthesis process to produce an effective, stable scented compound to meet the load requirements for integration into a solid material, like plastic. In view of the above, the design of a scented material requires a fine balance among synthesizing the scented compound to have the desired fragrance with appropriate load ratios and manufacturing a solid scented material with an optimal porosity that enables the adsorption of the volatile compounds, but also, the subsequent slow diffusion of the volatile compounds from the material.
Disclosed are scented material compositions, scented articles and methods and systems of their manufacture. In particular, the disclosed scented materials and articles include scented articles for a bottle cap system having a scented attachment for enhancing a user's sense of smell and/or taste of a beverage in the bottle.
The disclosed methods and systems for manufacturing such scented attachments include an integrated series of processes to produce a scented article that can deliver a chemically-designed scent or aroma that accurately simulates a familiar and pleasing smell to a user, such as a fruit flavor, a spice flavor, a candy flavor, and the like. The disclosed manufacturing methods and systems account for a plethora of processing parameters and constraints that, if not controlled, can cause undesired variations in the intermediary products that ultimately degrade the final scented material integral to the scented article, and thereby render an inaccurate or inferior scent from the scented attachment (and ruin the scent experience the user would otherwise enjoy while drinking the beverage).
In some example embodiments, a method for manufacturing a scented article, e.g., such as a scented attachment as described above, includes selecting a loading parameter (e.g., % wt, % mass, % mol, and/or volume) of a fragrance material with respect to a base material (e.g., plastic material, such as a polyolefin) to manufacture a scented material; melting the base material in a chamber including mechanically processing the base material to cause the base material to change from a solid phase to a liquid phase or liquid-like phase at a particular viscosity (e.g., in which the particular viscosity of the melted base material has a lower viscosity or viscosity range relative to the solid base material); mixing an amount of the fragrance material in accordance with the selected loading parameter with the melted base material at a predetermined temperature and pressure in the chamber to form an intermediary scented material; extruding the intermediary scented material through holes of an extrusion plate to form an extruded intermediary scented material; modifying the extruded intermediary scented material to form pellets; cooling the pellets in a fluid bath that prevents exposure of the pellets to air and/or atmospheric conditions (e.g., including temperature, humidity and/or oxygen); drying the cooled pellets without applying heat to produce the scented material; and producing a scented article including one or more of injection molding, compression molding, or other material processing technique using the scented material to form a desired shape of the scented article.
In some example embodiments, a system for manufacturing a scented article includes (i) a fragrance material processing system to formulate and/or maintain conditions of a fragrance material that includes an odorless carrier compound and a scent-flavor compound at a particular concentration up to 30% of the fragrance material; (ii) a material processing apparatus including a channel having a plurality of processing zones that includes a first zone to pre-process a base material (e.g., plastic material, such as a polyolefin) and a second zone to introduce and process the fragrance material at a selected load parameter (e.g., % wt, % mass, % mol, and/or volume) with the pre-processed base material; (iii) a continuous screw configured in the channel to produce an intermediary scented material from the processed base material and the fragrance material, in which the screw is operable in the first zone to transform the base material from a solid phase to a liquid phase through physical movement of the screw that mechanically contacts and churns the base material to create heat that melts the base material, and in the second zone to mix the fragrance material with the melted base material at a predetermined temperature in the second zone to form intermediary scented material; (iv) a shaping apparatus including an extrusion plate configured at the end of the channel and including a plurality of holes to extrude the intermediary scented material, and a cutting mechanism to reduce size and modify shape of the extruded intermediary scented material to form scented pellets from the cut and extruded intermediary scented material; (v) a cooling apparatus including a container having a fluid contained therein at a cooling temperature to receive and cool the scented pellets in the fluid that prevents air exposure to the pellets and thereby traps volatile fragrant constituents of the intermediary scented material in the intermediary scented material; (vi) a drying apparatus including a spin dryer to dry the cooled pellets without applying heat; and (vii) a molding apparatus to produce scented articles having a shape and size based on a mold using the scented pellets and/or (viii) a packaging apparatus to collect the cooled scented pellets or the produced scented articles and create a packaging to surround the scented pellets or articles in a manner that restricts air and contaminants from contact with the scented pellets or articles and controls the amount of air and pressure in the packaging.
In implementations of example embodiments of the disclosed methods and systems in accordance with the present technology, challenges to produce scented articles like the scented ring include selecting the right composition parameters of the fragrance material used in the manufacturing process (e.g., such as a fragrance compound in the form of an oil, emulsion or other liquid or liquid like phase). For example, the disclosed methods and systems include engineered fragrance compounds to be compatible with certain polymer base materials, such as polyolefin, in which the fragrance compounds are integrated into the base materials at particularly high loads of the fragrance compound, such as in % concentration or % wt ranges of 10% or greater, e.g., 10-30% fragrance oil. For example, the process of manufacturing the scented material (e.g., in the form of scented pellets) requires determining conditions that provide a material with the right chemical properties to (1) adsorb the fragrance compound and (2) control the release of fragrance compound as a function of time.
In some example embodiments of the fragrance material used to produce scented materials and articles in accordance with the present technology, the fragrance material can include an odorless flavor carrier compound and a scent flavor compound. In some embodiments, the odorless flavor carrier compound includes medium chain triglyceride (MCT) and Triacetin (1,2,3-triacetoxypropane). In such embodiments, for example, the flavor or fragrance material, such as fragrance oil, includes MCT, Triacetin, and the scent-flavor compound, in which the MCT includes a % wt in a range of 50-80% wt, the Triacetin includes a % wt in a range of 15-25% wt, and the scent-flavor compound includes a % wt in a range of 1-30% wt. In some examples, the fragrance oil includes MCT at a 50-70% wt range (e.g., 60% wt), triacetin at a 15-25% wt range (e.g., 20% wt), and the scent-flavor compound at 15-25% wt range (e.g., 20% wt). Table 1 shows an example formulation of a fragrance material (e.g., fragrance oil) in accordance with the present technology, showing a range of weight percentages for constituents of the fragrance material.
Some example scent-flavor compounds used in the example methods and systems in accordance with the present technology include, but are not limited to, 15-30% caproates, for example, natural allyl caproate or ethyl caproate for the scent-flavor Pineapple; passionfruit sulfur, for example, methyl 4-propyl 1,3-oxathiane for the scent-flavor Passionfruit; tangerine oil for the scent-flavor Tangerine; ocimenes and menthanethiol or mercaptan for the scent-flavor Mango; lime oil for the scent-flavor Lime; and peppermint oil and menthol for the scent-flavor Mint.
Some of the scent flavor compounds, such as methyl 4-propyl 1,3-oxathine, for example, have a relatively a high vapor pressure (e.g., evaporate rapidly under atmospheric conditions) and can be hard to prevent their diffusion from scented materials. This further illustrates that the disclosed methods and systems (e.g., such as the method 1400 and the system 1500 discussed below) provide effective and efficient techniques for producing scented materials and scented articles, such as the scented ring 610 and/or other examples of the scented rings, when using such constituents to produce the fragrance material.
The method 1400 includes a process 1410 to receive a base material, e.g., plastic material such as polyolefin, in a processing chamber and melt the base material to a liquid or liquid-like phase, e.g., having a particular viscosity or viscosity range. In some examples, the viscosity range includes 10 mPa·s to 75 mPa·s, e.g., at temperatures between 95-300 degrees Fahrenheit (° F.). In some implementations, the process 1410 includes mechanically mashing the base material to melt it into a liquid or liquid-like phase of the material. For example, in such implementations, conditions in the processing chamber are controlled through the mechanical processing which holds the mashed and melted material at a controllable temperature and pressure, and thereby reach and maintain a desired viscosity of the base material in the chamber. In some implementations, the temperature in the chamber is maintained in a range between 260-280 degrees Fahrenheit (° F.). In some implementations, the process 1410 includes initially applying heat to the processing chamber, such that the chamber and/or portions of the mechanical processing machine in the chamber are at an elevated temperature, in which the mechanical processing causes an increase in temperature of the base material as it is mashed to cause the melting to the liquid or liquid-like phase. For example, in such implementations, absent the mechanical processing, the base material would remain solid in the chamber. Importantly, the optimization of the mechanical mashing and melting of the base material as described in and the process 1410 can enable the conversion of the base material into a liquid or liquid-like phase, which is required to effectively mix the materials (e.g., base material and fragrance oil). In some embodiments, the method 1400 includes a process to controllably feed the base material into the processing chamber based on the measured values (e.g., weight amount) of the base material in a feeder that supplies the material in the chamber.
The method 1400 includes a process 1420 to receive the fragrance material, e.g., a fragrance oil, in the processing chamber and mix the fragrance material and melted base material at controlled temperature and pressure in the chamber to form an intermediary scented material. In some implementations of the method 1400, the process 1405 or 1420 includes selecting a loading parameter of the fragrance material, such as the % wt, % mass, % mol, and/or volume of the fragrance material, to be processed with the base material to manufacture the intermediary scented material to have a particular % concentration or concentration range of the fragrance material in the base material (e.g., scent loading in a range of 1% to 30%). In some implementations, the process 1420 includes generating different temperatures and pressures in a different region or regions of the chamber to process the mixed materials and form the intermediary scented material. For example, the process 1410 may include a first temperature and/or pressure to melt the base material to the liquid or liquid-like phase, and the process 1420 may include a second temperature and/or pressure to combine the fragrance material and the melted base material to form the intermediary scented material. In some embodiments, the method 1400 includes a process to controllably feed the fragrance material into the processing chamber based on the measured values (e.g., weight and/or volume amount) of the fragrance material in a feeder that supplies the material in the chamber. In some embodiments, the method 1400 includes a process to receive and mix one or more additional compounds or materials with the melted base material and the fragrance material, e.g., such as a colorant.
The fragrance material produced from the process 1405 is a fragrance or aroma substance used in the process 1420 to engineer a specialized material that exhibits a scent for a variety of scented articles. For example, not all fragrance compounds are compatible with certain polymer base materials, particularly with high loads of the fragrance compound (e.g., fragrance oil) in % wt ranges of 10% or greater, e.g., 10-30% fragrance oil. As a result, identifying the right combination of materials requires a rigorous optimization processes involving the variation of numerous materials processing parameters (e.g., temperature, specific amounts of the material, order of addition, etc.) to arrive at a stable, scented material that can encapsulate and retain scent. In particular, the experimental conditions and combinations of polymer base materials and fragrant compounds can have a directed effect on the ability of the material to retain the scent.
The method 1400 includes a process 1430 to receive and modify the shape and/or size of the intermediary scented material through extrusion. For example, in some implementations, the process 1430 includes forcing the intermediary scented material, which is soft and malleable, through holes having a shape and size to form elongated, tubular configurations of an extruded material, e.g., like a spaghetti-like form. In implementations, for example, the process 1430 outputs the extruded material in a container of fluid (e.g., water or other biocompatible or nontoxic aqueous fluids or fluidic substances, like an oil or organic solution). The fluid helps to prevent volatile fragrant compounds from escaping the extruded material.
The method 1400 includes a process 1440 to receive and further modify the shape and/or size of the extruded materials to a small size, e.g., by cutting to form particles. Some examples of the shape-modified scented particles include uncurved-shaped particles or curved-shaped particles like spherical, oval, cylindrical or conical particles, or uncurved shaped particles, e.g., pellets having a dimension in a range of 1/16 inch to ¼ inch. In implementations, the process 1440 includes depositing the scented particles (e.g., cut pellets) of the extruded material in a container of a fluid (e.g., water or other biocompatible or nontoxic aqueous fluids or fluidic substances, like an oil or organic solution).
The method 1400 includes a process 1450 to receive the scented particles and cool them to a desired temperature (or temperature range) in a manner that prevents volatile fragrant compounds to escape (e.g., diffuse) out of the intermediary scented material during the cooling stage, e.g., by evaporation. In some examples, the desired temperature or temperature range includes at or around room temperature or, in some implementations, in a temperature range of 15-30° C. In some implementations, the process 1450 includes passing the scented particles through a fluid bath (e.g., water bath) to cool the scented particles (e.g., pellets) such that there is no exposure of the scented particles to air and atmospheric conditions while cooling. For example, in such implementations, the fluid (e.g., water) can be pumped in a direction to allow the scented particles to flow through the fluid bath while cooling.
For example, the process 1450, which includes cooling the example pellets in a fluid bath, enables the rapid cooling of the pellets to trap volatile fragrant compounds in the pellets, in which cooling the pellets in a fluid bath provides a pressure greater than the atmosphere such that the pellet is surrounded by a medium dense enough to prevent diffusion (e.g., evaporation) of the scented material. In some implementations, the cooling process may partially occur during the process 1440 and/or the process 1450.
The process 1450 prevents exposure of the scented particles to air and/or atmospheric conditions in order to increase the stability of the resulting particles. For example, implementation of this process precludes altering the composition of the scented pellet by preventing exposure to elements from the air and atmosphere (e.g., temperature fluctuations, changes in humidity, and reactivity of atmospheric gases (e.g., dioxygen)) that could degrade the scented pellet. This process also prevents mixing of contaminants from the atmosphere with the base material in order to ensure that the integrity, that is the scent and stability, of the scented pellet is maintained.
The method 1400 includes a process 1460 to dry the cooled, scented particles and produce the scented material. In some implementations, the process 1460 includes spin drying the intermediary scented material (e.g., particles, in the form of pellets) after it has been cooled to the desired temperature, e.g., in which the spin drying does not include applying heat but can maintain a specific temperature, as applied heat can accelerate volatility of the fragrant compounds formed in the intermediary scented material. The scented material produced by the method 1400 can be used to produce a variety of scented articles, such as the example embodiments of the scented ring described herein.
In some embodiments, the method 1400 can further include a process 1470 to package the dried scented material produced by the process 1460 (e.g., such as the dried scented pellets) in a sealed container. In some implementations of the process 1470, for example, the sealed container includes a vacuum sealed container. For example, the vacuum sealed container can minimize any head room and remove contaminants, like oxygen in air, from the container while the produced scented material (e.g., pellets) remain in packaging for their desired application or use, such as during transit and storage. In certain examples, the vacuum sealed container includes a bin or a bag with aluminum interior lining to prevent evacuation of the scent chemical integrated in the scented material.
In some embodiments, the method 1400 can further include a process 1480 to fabricate a scented article, such as the scented ring 610, 1110, 1120, 1200, 1210, 1220 and/or other examples of the disclosed scented ring, by material-processing the dried scented material (e.g., pellets). For example, in some implementations, a predetermined quantity (e.g., volume and/or mass) of the dried scented material is inputted into a molding machine to compression mold or injection mold the scented article to have a desired design, like a ring, in which, the shape and size of the scented article may be based on the mold. In some implementations, the example molding process of the dried scented material can include venting during molding to allow heat produced during the molding to escape to maintain a favorable temperature and/or pressure of the material being molded into the scented article, e.g., as increased pressure can cause scarring of the final molded product. In some implementations, the example molding process includes cooling the molding material to a temperature that can help prevent volatile chemicals from escaping the scented material. For example, in some implementations, the material-processing of the dried scented material can include adding a colorant, adhesive, or other chemical additive to fabricate the scented article. In various implementations, for example, the process 1480 can be implemented following the process 1460 or 1470.
In some implementations, the method 1400 can further include a process to vacuum seal the scented article in a packaging, e.g., to prevent air, contaminants, or any atmospheric conditions to contact and/or affect the scented article and thereby threaten the quality of the manufactured product. For example, the vacuum sealed packaging can include a bag with aluminum interior lining to prevent evacuation of the scent from the scented article.
The base material 1501 can include polyolefin polymer materials. Examples of polyolefin materials used as the base material 1501 include, but are not limited to, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), polypropylene (PP), and/or LDPE EVA (ethylene vinyl acetate) copolymer, or any blend of these polymers. The new, scented material to be produced using the system 1500 will release a scent when exposed to air, and as such, the base material 1501 to be processed should be selected to have material properties that encapsulate and/or enhance oil retention, stiffness, processability for the scented material. The materials used in the system 1500 can preferably include materials having a flashpoint above 140° F., e.g., to ensure safety in the manufacturing processes.
In some example implementations of methods for manufacturing scented materials, the base material 1501 can include a flex PVC (polyvinyl chloride), cellulose acetates, or polystyrene. Yet, these example materials may require very high temperatures (e.g., over 300° F.) for processing, may be very stiff, and/or may degrade in the presence of the fragrance material, and therefore are not optimal base materials for processing using the system 1500. In some implementations, the base material 1501 can include polymer blends with rubber, such as polyether block amides like Pebax®, which allow oils to be absorbed. Notably, Pebax® is currently an expensive material (e.g., around $6/lb.), and may not be optimal for applications in which cost is a constraint.
The system 1500 includes a kneading assembly 1515 configured in the first receiving zone 1510 and structured to include a chamber and a continuous screw in the chamber that operates to melt the solid phase of the base material 1501 to the liquid or liquid-like phase base material 1502 in the kneading assembly 1515 through physical movement of the screw creating heat to melt the base material 1501 and regulating temperature and pressure of the chamber. The operation of the kneading assembly 1515 provides control of temperature and pressure that are applied to the material inside the kneading assembly 1515. The screw of the kneading assembly 1515 can be structured as a segmented screw. For example, in certain embodiments, the screw can include a twin screw or single screw. In implementations, the screw of the kneading assembly 1515 can move by ‘reciprocating’ back and forth. The chamber of the kneading assembly 1515 can be configured as a sealed chamber that maintains pressure and temperature regulation inside the kneading assembly 1515.
The example kneading assembly 1515 operates to create a controllable temperature and pressure to mechanically mash and melt the base material 1501 (e.g., plastic) into a liquid, in which pressure is not a setting. Temperature is used to maintain viscosity of the material in the assembly 1515 and hold the material in a liquid or liquid-like state. In some examples, the viscosity range includes 10 mPa·s to 75 mPa·s, e.g., at temperatures between 95-300 degrees Fahrenheit (° F.). In some implementations, the kneading assembly 1515 operates to regulate the material processing temperature in a range of 260-280 degrees Fahrenheit (° F.), e.g., to melt a solid plastic like polyolefins, in the first receiving zone 1510. For example, the physical structure and motion of the screw generates mechanical energy (e.g., torque) that can provide sufficient heat to initially melt the plastic and maintain the melted plastic in the liquid or liquid-like state throughout the production process.
In some embodiments of the kneading assembly 1515, for example, external heaters are not required to melt the plastic. Yet, in some embodiments, for example, the first receiving zone 1510 can additionally or alternatively include a heating unit that applies heat to melt, or assist in melting, the solid base material 1501 to the liquid or liquid-like material 1502 in the chamber. For example, in such implementations, heat can be initially applied to the processing chamber in the zone 1510, such that the chamber and/or the screw of the kneading assembly 1515 are raised to an elevated temperature, but not hot enough to cause melting of the base material 1501, in which the mechanical processing causes an increase in temperature of the base material 1501 as it is processed by the kneading assembly 1515 to produce the base material 1502. For example, in such implementations, absent the mechanical processing by the kneading assembly 1515, the base material would remain solid in the chamber.
The system 1500 includes a second receiving zone 1520 to receive a fragrance oil 1505, e.g., such as an aromatic composition comprising one or more scented chemical constituents mixed with other substances to form a scented oil or other non-solid fragrant. The second receiving zone 1520 is configured proximate to the first receiving zone 1510 of the system 1500 to receive the liquid or liquid-like base material 1502, e.g., liquefied plastic processed by kneading assembly 1515, which is combined with the fragrance oil 1505 received in the zone 1520. As shown in the example of
In implementations, for example, the kneading assembly 1515 is operable to generate different temperatures and pressures in different regions of the assembly. For example, in some implementations, the kneading assembly 1515 in the second receiving zone 1520 can operate to raise the temperature of the mixed materials to a second temperature (e.g., ˜220° F.) while being churned and pushed through the assembly 1515.
In some embodiments, the kneading assembly 1515, in the first receiving zone 1510, includes one or more a restriction rings so the solid base material 1501 never crosses into the second receiving zone 1520. Therefore, in such embodiments, only the melted material 1502 (e.g., liquid plastic) can migrate to the second receiving zone 1520, e.g., the fragrance/aroma zone. If the solid base material 1501 (e.g., plastic) is not melted by the portion of the chamber where a restriction ring is positioned, the solid base material 1501 gets pushed back until its melted to a form that the restriction ring allows to pass. In some embodiments, the one or more restriction rings include multiple restriction rings with narrowing sizes that narrow down space in the chamber. Similarly, for example, the kneading assembly 1515 is structured to keep oil out of the melting process in the first zone 1510 In implementations, for example, the fragrance oil 1505 is injected into the melted base material 1502 after the solid base material 1501 has melted, which can include processing the solid base material 1501 in the first receiving zone 1510 to have a certain viscosity or viscosity range (10 mPa·s to 75 mPa.$). In some implementations, for example, the melted base material 1502 is processed to have a viscosity that matches the viscosity of the received fragrance oil 1505. For example, the viscosity of the received fragrance oil 1505 can be in a range of 1 mPa·s to 10 Pa·s at room temperature.
In certain embodiments, the feeders 1511 and/or 1521 include a scale to measure mass of the raw materials 1501 and/or 1505 to control the timing, rate, and/or amount of the materials to be released in the respective zones. In accordance with some embodiments of the method 1400, the system 1500 can provide colorant constituents to be mixed with the materials. For example, color can be received at a region of the first receiving zone 1510 to be mixed with the base material 1501 as it is melted by the kneading assembly 1515. In some implementations such as those with a liquid or liquid like raw base material 1501, for example, color can be mixed with the base material 1501 in the first feeder 1511. Similarly, color can be mixed with the fragrance oil 1505 in the second feeder 1521, and/or color can be received at a region of the second receiving zone 1520 to be mixed with the mixed constituent materials 1502 and 1505 as they are churned by the kneading assembly 1515. The sealed chamber of the kneading assembly 1515 can prevent air, contaminants, or any atmospheric conditions to contact and/or affect the fragrance oil 1505 and/or the mixed constituent materials 1502 and 1505 to form the intermediary scented material 1522.
For example, the sealed chamber prevents exposure of the intermediary scented material 1522 to air and/or atmospheric conditions to enhance the stability of the resulting material by precluding reactivity with elements from the air and atmosphere (e.g., temperature fluctuations, changes in humidity, and reactivity of atmospheric gases (e.g., dioxygen)) that could degrade the intermediary scented material 1522).
In some implementations, the system 1500 utilizes the feeders 1511 and/or 1521 to starve-feed the kneading assembly 1515. That is, the feeders 1511 and/or 1521 determine how the screw moves based on the measured values of what is in the feeder, e.g., weight amount. As an example, the feeders 1511 and/or 1521 can measure a relatively high weight of the raw materials that corresponds to a first speed of the screw turning; and the feeders 1511 and/or 1521 can measure a lower weight of the raw materials in the feeder(s) that corresponds to a second speed of the screw turning. As such, the fragrance oil 1505 can be injected into the system 1500 on a computerized loss and weight feeder.
In some implementations, the base material 1501 may already be in the form of base material 1502, i.e., liquid or liquid-like form, e.g., capable of flow. In such implementations, the liquid base material 1502 and the fragrance oil 1505 can be added at the same point of entry at the kneading assembly 1515 in the chamber, in which the first and second receiving zones 1510 and 1520 are the same physical zone, but may vary from a temporal aspect as to when the materials 1501 and 1505 are received.
In other embodiments, one or both of the first and second receiving zones 1510 and 1520 can include a continuous mixer assembly or a batch mixer assembly to mix the base material 1501 and the fragrance oil 1505.
The system 1500 includes a zone 1530 to receive and process the intermediary scented material 1522 produced by the kneading assembly 1515 to modify its shape and size, e.g., by extrusion. In some embodiments, the zone 1530 includes an extrusion plate, e.g., a metal face plate, with a plurality of holes configured perpendicular with the material flow direction at the end face of the kneading assembly 1515. For example, an extruded material 1533 is formed in elongated shapes and sizes defined by the holes of the plate. In some embodiments, the system 1500 includes a container of a fluid (e.g., water or other biocompatible or nontoxic aqueous fluids or fluidic substances, like an oil or organic solution) in the zone 1530, in which the intermediary scented material 1522 is received and modified, e.g., by extrusion. In some implementations, the extruded material 1533 is forced out of the kneading assembly 1515 through the holes of the extrusion plate in the zone 1530 in a spaghetti-like form.
In some embodiments, the system 1500 includes a zone 1540 to receive and process the extruded material 1533 to further modify its shape and size, e.g., such as cut to form scented particles, including beads, pellets or other smaller particles. In some embodiments, the system 1500 includes a container of a fluid (e.g., water or other biocompatible or nontoxic aqueous fluids or fluidic substances, like an oil or organic solution) and a blade cutter in the zone 1540, in which the blade cutter cuts the shape-formed extruded material 1533 to scented particles 1544 (e.g., pellets) submerged in the fluid. In some implementations, for example, a blade of the cutter spins behind the metal plate with holes and cuts the spaghetti-like extruded material 1533 into small scented particles 1544. For example, the size of example pellets can include a ⅛ inch round size. In some implementations, the pellet size is not essential if the method for manufacture includes a re-melting process. Whereas, in some embodiments, the system 1500 provides the extruded material 1533 directly to a cooling zone, discussed below.
The system 1500 includes a cooling zone 1550 including a fluid (e.g., water or other biocompatible or nontoxic aqueous fluids or fluidic substances, like an oil or organic solution) at a predetermined temperature to receive the cut scented particles 1544 and cool them to a desired temperature (or temperature range) to form a scented material 1555, e.g., in the shape of scented particles or other shape of the intermediary scented material 1522 after the zone 1530. In some examples, the desired temperature or temperature range includes at or around room temperature, or in some implementations in a temperature range of 15-30° C. In some embodiments, the cooling zone 1550 includes a fluid bath (e.g., water bath) arranged at the end of the kneading assembly 1515 to span between the zones 1530, 1540 and 1550, including after the extrusion plate and the cutter, which receives the scented particles 1544 and flows them in the fluid bath along a channel to be cooled to the desired temperature or temperature range. For example, in some implementations, the cooling zone 1550 can include a pump 1557 that pumps fluid in the fluid bath to create a flow that can drive the scented particles 1544 from one region of the water bath to another region of the water bath of the cooling zone 1550. In the cooling zone 1550, the fluid (e.g., water) is circulated back and forth and temperature controlled. In some implementations, the fluid (e.g., water) in the cooling zone is set to a predetermined temperature of 80-85° F. In an example embodiment, the water bath is structured as a stainless steel tube to span a distance (e.g., 30 ft.) to facilitate the example pellets traveling the distance of the tube in the fluid.
The cooling zone 1550 provides a cooling module that prevents the volatile constituents of the intermediary scented material (e.g., formed as the particles, such as pellets) from immediately escaping the formed material. The cooling zone operates by slowing down the sublimation process of the scented materials (e.g., where the scented material is converted to a gas (vapor) and is released into the atmosphere) in order to effectively trap the scent in the scented materials. To form a scented material in accordance with the present technology, the intermediary scented material must be cooled to a desired temperature using a fluid to trap the volatile chemicals from escaping (e.g., evaporating), which could otherwise escape in air. In some embodiments, after the scented particles 1544 are cooled to the desired temperature in the cooling zone 1550, e.g., room temperature (e.g., 22-27° C.) or just above room temperature, the cooled scented material 1555 can be dried by spin drying and/or applying a gas (such as nitrogen) or air.
For example, in implementations, cooling the scented particles in a fluid bath enables the rapid cooling of the particle to trap volatile fragrant compounds in the scented material as a consequence in the difference between the heat capacity of water vs air. Also, for example, cooling the scented particles in a fluid bath provides a pressure greater than the atmosphere such that the particle (e.g., pellet) is surrounded by a medium dense enough to prevent diffusion (e.g., evaporation) of the scented material.
For example, preventing exposure of the scented material to air and/or atmospheric conditions during the manufacturing increases the stability of the resulting scented particle by precluding contamination with elements from the air and atmosphere. Such elements in the air and atmosphere can include, but are not limited to, fluctuations in temperature, changes in humidity and reactive of atmospheric gases (e.g., dioxygen) that could degrade the scented material. Also, for example, preventing exposure from air and atmosphere excludes the incorporation of impurities into the scented particles that could affect the particle's scent and stability.
The system 1500 includes a drying zone 1560 to dry the cooled, scented material 1555 (e.g., particles, such as pellets, beads, etc.) to produce an engineered scented material 1566. In some embodiments, the drying zone 1560 includes a spin dryer to spin dry the cooled, scented material 1555. The scented particles are not heated in the drying zone 1560, as applied heat can accelerate volatility of the fragrant compounds formed in the cooled, scented material 1555. In some embodiments, the drying zone 1560 can also include a packaging system to receive the dried, engineered scented material 1566 (e.g., formed as pellets) and seal the engineered scented material 1566 in one or more sealed containers 1571. In some embodiments, the packaging system of the drying zone 1560 is arranged adjacent and separate from the spin dryer or other example drying apparatus. In such embodiments, the dried, engineered scented material 1566 are provided to the packaging system, which includes one or more openings at a terminal end to allow the one or more sealed containers 1571 to reversibly fasten so that the engineered scented material 1566 can be packaged within the sealed container(s) 1571 that minimizes exposure to air, moisture, and contaminants.
In some embodiments, the system 1500 can further include article processing machine or system 1580 to receive the engineered scented material 1566, e.g., directly from the drying zone 1560 or indirectly from the drying zone 1560 via from a packaging like container 1571, and to process the engineered scented material 1566 to produce a scented article 1588. In some embodiments, the article processing machine 1580 includes a compression molding or injection molding machine to fabricate the scented article 1588 based on a mold having a predetermined shape and size to create the article, such as a scented ring, scented sheet, or other design of the scented article. In some examples, the article processing machine 1580 includes a hot runner mold system or a gated molding system. In certain embodiments, for example, the gated molding system includes one or more mold chamber shaped to dimensions of a ring, and a small tube component that connects with the mold chamber to provide a gate to expel waste product (e.g., which can be recycled). For example, the body of the scented article 1588 may be fabricated using compression molding, during which process the engineered scented material 1566 is shaped based on the mold and may include a colorant, adhesive, or other chemical additive be added to the article, in which the compression-molded end product includes color, and/or an additive is used to aid in the release of the product from the mold. In some examples, the scented article 1588 is made from a single piece of shaped or otherwise molded material and may include a cavity into which the engineered scented material 1566 is injected.
In some embodiments, the system 1500 can further include an article packaging machine or system 1590 to package the scented article 1588 in a manner that restricts air and contaminants from contact with the scented articles and controls the amount of air and pressure in the packaging. In some implementations, the article packaging machine 1590 provides a vacuum sealed packaging 1598, e.g., in which a predetermined amount of scented articles 1588 of the same fragrance or aroma are packaged in a single vacuum packaging. For example, the predetermined amount can be selected by quantity of scented articles 1558, by weight of scented articles 1558, by volume of scented articles 1558, or the like. In some implementations, the article packaging machine 1590 separates the inputted scented articles 1588, based on the batch order of input, such that scented articles of a first scent (e.g., mint) are packaged in a separate packaging from scented articles of a second scent (e.g., pineapple).
In some implementations of methods for manufacturing using the system 1500, the time between initiating feeding of the materials 1501 and 1505 and the pellet formation can include producing 500 lbs. of the produced material (pellets) per hour. As such, a single pellet 1544 can be produced in the zones 1510-1540 in approximately 15 seconds. In some implementations, the dwell time in the cooling zone includes only a few seconds (e.g., 2 to 5 seconds). Spin drying the example scented pellets can include times of a few seconds to one minute, in some examples. Therefore, methods for manufacturing scented materials using the system 1500 can produce a container of the scented material 1566 in under a minute.
In some example embodiments, a method for manufacturing a scented material (example D1) includes melting a base material (e.g., plastic material) in a chamber including mechanically processing the base material to cause the base material to change from a solid phase to a liquid phase or liquid-like phase at a particular viscosity; mixing a fluid fragrance material with the melted base material at a predetermined temperature and/or pressure in the chamber to form an intermediary scented material; extruding the intermediary scented material through holes of an extrusion plate to form an extruded intermediary scented material; cooling the intermediary scented material in a fluid bath that prevents exposure of the intermediary scented material to air and/or harmful atmospheric conditions including temperature, humidity and/or oxygen; and drying the cooled scented material without applying heat to produce a scented material.
