1. Field of the Invention
This invention relates to systems for dispensing a beverage. The invention also relates to capsule used in a system for dispensing a beverage and methods of dispensing a beverage from a capsule.
2. Description of the Related Art
There are a number of devices and techniques for dispensing a beverage such as, for example, a cup of coffee or tea from a capsule. In one approach a disposable container fits on top of a cup and has a compartment for receiving a beverage extract such as coffee with a large reservoir on top into which a person must pour boiling water. These devices can be disposable but expensive, the coffee is exposed to the air where it can easily get stale or contaminated, and they are not generally suitable for automatic coffee making or other beverage machines. Because the flow rate of beverage is generally slow, these devices are typically large relative to the volume of beverage dispensed. Also, these devices can be designed to be used upright and only the bottom area is available for filtration flow and this contributes to the slowness of the filtration process. In one construction, a filter is provided in a sealed receptacle and a support member is included intermediate the receptacle and filter which functions to support the filter. When the filter is wetted, it sags and conforms with the support member which has a hole in it to release the filtered beverage but otherwise blocks the output of the filter. Such a filter design used in an application where water is injected under pressure would provide low flow rates.
There are several known companies operating proprietary capsule based machines in the coffee and tea space, including Nestlé's Nespresso and Special T, Green Mountain Coffee Roaster's Keurig, Starbucks Verismo, Kraft's Tassimo, Sara Lee's Senseo, Nescafe's Dolce Gusto, Illy, Lavazza's Blue and Britta Yource. Mars Flavia and Esio are machines utilizing a pouch-style single use dispensing system. Additionally, there are several known companies operating single serving drink machines in the commercial environment, including PHSI's Interpure, Waterlogic's Innowave, Vertex's Charm, Keurig, Nestlé and Mars Flavia.
Currently, there are other machines attempting to commercialize a similar capsule/pod based single-serve point of use cold beverage system. For example, Omnifrio, acquired by Primo Water, uses a puncture mechanism, which punctures the top and bottom of the capsule allowing a syrup concentrate to drain out. Bevyz uses a pressure mechanism to pop open the capsule to enable a mixing process. The Esio Hot & Cold Beverage System uses a syrup pouch system and pumps drink mix out of the pouch to mix it with water outside of the packet. Yource by Brita uses a capsule based machine.
When cold drinks are dispensed in a system in which the beverage is prepared by mixing cold fluid, usually water, with a powder instead of a liquid concentrate, one significant challenge is that the powder will not dissolve effectively during the mixing process. This can lead to poor quality output from the beverage system and unsightly and possibly unhealthful residue in the machine itself. Improved systems for providing a hot, cold, ambient temperature, carbonated, still mixed beverage designed to enable the effective mixture of the powder with the liquid during dispensing providing for little or no residue, contamination, or cross contamination between beverages are described in U.S. application Ser. No. 13/293,043, U.S. Provisional Application No. 61/411,786, and International Application No. PCT/US2011/060050, all of which are hereby incorporated by reference. The present disclosure describes an additional embodiment for providing mixed beverages.
The purpose of the invention is to offer a compelling alternative to bottled water and other water based ready-to-drink (RTD) beverages. The invention is meant to offer a convenient, reliable, and cost effective Point of Use solution to the consumer's hydration and beverage needs. The invention is a single-serve beverage system that can produce unlimited chilled filtered water as well as single serve unique beverages through a proprietary capsule-based system. The invention can be cold, hot, still (i.e., not sparkling), carbonated, flavored, enhanced, ultra purified filtered waters and flavors.
The capsules contain a powder or a liquid, which is mixed into the filtered water to produce the beverage. The drinks can be “house formulas” or common mass market branded beverages licensed from the manufacturers.
The varied embodiments of the invention have multiple benefits:
The cracking and peeling method of accessing the capsule offers an effective and efficient way to prepare and deliver a beverage. A mechanical device is adapted to crack the capsule along a crease punched into the capsule below the top cover of the capsule. The mechanical device peels open the capsule along the cracked crease. For example, a slight crease could be included in a lip of the capsule that can be used to break the seal and allow the cover to then be peeled back. Forces may be applied to the capsule to open the capsule at the creases to access the beverage. When the cover is peeled back (e.g., tearing open the capsule) the drink is mixed with a mixing stream of liquid, which in many embodiments will be water, either cold or hot, sparkling or still. Testing in a fully functional prototype has been successful in flushing a drink powder concentrate out of a capsule.
According to some embodiments, it is advantageous to promote a controlled tear in the crease of the capsule to ensure a smooth opening of the capsule. The controlled tear can serve to lower the force required to open the capsule and/or provide a more uniform and repeatable tear to open the capsule. A raised leading edge on the mechanism used to open the capsule can serve to provide a controlled tear. The raised leading edge can be located such that it would facilitate opening the capsule along a longitudinal center line of the capsule or it may be off the centerline of the capsule so that the peel will be initiated off the centerline and travel along a crease to open the capsule.
These illustrations are illustrative of the present disclosure and should not be interpreted to limit the scope or range of the invention presented in this application.
The present disclosure relates to dispensing of a substance from a container by means of a dispensing apparatus. Specifically, the exemplary embodiments of the present invention relate to: (1) a capsule, (2) a dispenser for receiving the capsule, and (3) mechanisms within the dispenser to perform processes for opening the capsule and rotating the capsule while dispensing the mixed contents from the capsule into a user's beverage receptacle or glass. Each of these areas will be described in more detail below.
(1) the Capsule:
As shown in
The capsule 11 includes a concave basin 112 extending below the capsule 11 top 111, with an opening defined by the circumferential and planar rim. The basin 112 forms a receptacle for holding one or more mixing agents, such as powders or liquids for mixing a beverage. For example, the basin 112 may be formed and filled with a mixing agent, after which the opening defined by the rim of the basin 112 may be sealed by affixing the cover of the capsule 11 top 111 to the rim.
When the capsule 11 is viewed from the top, the basin 112 may appear as a variety of shapes, such as axisymmetric shapes including a diamond or oval. The basin 112 may be formed according to a variety of sizes to accommodate a variety of quantities of mixing agents for a variety of sizes of mixed beverages. For example, the basin 112 may have a capacity or volume of approximately forty cubic centimeters (i.e., 40 cc). The volume of the basin 112 may be greater than the volume of the quantity of mixing agent sealed within the capsule 11 so as to leave room for portions of the beverage to be mixed within the capsule 11.
The basin 112 includes the planar circumferential rim to which the capsule 11 top 111 may be affixed. The rim may be wide enough to form a lip that is shaped to allow for a snug and secure fit of the capsule 11 within a dispenser 100 while the beverage is being mixed. The basin 112 may also have a crease or seam punched into the basin 112 below the capsule 11 top 111. The crease, which may be a pre-weakened portion of the capsule 11 under the rim, may be designed so that when the opening mechanism of the dispenser 100 applies forces to the capsule 11, the capsule 11 may be cracked and peeled open along the crease, forming an opening at an end of the capsule 11. The opening may be shaped to allow a fluid such as water to be injected into the capsule 11 for dissolving or mixing the mixing agent within the capsule 11. In addition, the opening may also be shaped to allow the mixed content to flow out of the capsule 11. In some embodiments, the capsule 11 may be designed for single use, and the capsule 11 may be removed, ejected, or otherwise discarded or recycled after making the beverage. In some embodiments, the capsule 11 may have additional pre-weakened portions, such that the capsule may be cracked and peeled at additional location to create more than one opening in the capsule. For example, openings may be formed in two ends of the capsule.
The volume of the capsule and the amount of mixing agent initially present in the capsule 11 may vary depending on the volume of the beverage. In some embodiments, the volume of the capsule 11 may be approximately 30 cc, and the capsule 11 may contain approximately 2-6.5 grams of mixing agent. In other embodiments, the capsule may contain approximately 15-20 grams of mixing agent.
The geometry of the opened capsule 11 may be optimized to maximize the mixing action and subsequent drainage of the mixed contents of the capsule 11 while directing the drainage to minimize any mess or cross-contamination between beverages caused by the mixed contents flowing out of the capsule 11. Additionally, the opening mechanism of the dispenser 100 may be designed to minimize the risk of contaminating the contents of the capsule 11 and the subsequent mixed beverage. For example, the opening mechanism may avoid introducing contaminants to the interior of the capsule 11, and the opened capsule 11 may permit fluid injection and mixture draining while avoiding contaminants on the exterior of the capsule 11 or the interior of the dispenser 100.
Another advantage of the present disclosure is that the exterior of the capsule 11 does not come into contact with the mixed beverage. There is no contact of finished product with the outside of the capsule 11, as there is no puncture of foil lid or capsule 11 base into the beverage, ensuring that the beverage maintains sterile. Most machines have contact of the outside of the capsule 11 and the finished beverage, which is not hygienic because the outside of the capsule 11 has been handled in a non-sterile fashion.
In some embodiments, the exterior of the capsule 11, such as an exterior side of the basin 112, may include optional encoded information 113, such as a barcode printed on the basin 112. The encoded information may identify aspects of the capsule 11 or its mixing agents to a sensor or scanner on the dispenser 100, such as a barcode reader, so that the dispenser 100 may adjust its beverage mixing processes accordingly. In other embodiments, the encoded information 113 may be encoded as a two-dimensional data matrix, such a Quick Response Code (“QR Code”). The scanner 114 on the dispenser 100 may be a camera capable of capturing the optical image of the encoded information for processing by one or more processors in communication with the camera.
Depending on whether the device is implemented in a business, in a home, or in another channel, the device may incorporate additional features, such as a locking feature. In some embodiments, the exterior of the capsule 11, such as an exterior side of the basin 112, may include optional printed graphics. For example, the capsule 11 may depict a trademarked image or logo. The scanner 114 (e.g., camera) of the dispenser 100 may be configured to capture the optical image of the graphic for processing by one or more processors in communication with the scanner 114. In conjunction with the processors and firmware, software, or another processor readable medium, the dispenser 100 may be in a locked state until a capsule 11 with an authentic and authorized graphic is inserted into the dispenser 100 in a correct orientation. After the graphic has been detected, the dispenser 100 may be in an unlocked state and proceed to mix a beverage with the contents of the inserted capsule 11.
In other embodiments, the encoded information may include information as to the optimal beverage parameters for a particular capsule. For example, if the coded information includes recipe information, the scanner 114 may be configured to capture the encoded recipe information for processing by one or more processors in communication with the scanner 114. In response to the processor(s) and firmware, software, or another processor readable medium, the various robotic actions of the dispenser 100, such as the volume of liquid in the pre-wetting stream, amount of total liquid dispensed by the mixing stream, and other parameters, may be adjusted to comply with the encoded recipe information.
A processor may be configured with a non-transitory processor readable medium comprising instructions that cause the processor to operate in accordance with embodiments of the present disclosure.
(2) the Dispenser:
Another aspect of the disclosure is the dispenser 100 for receiving a capsule 11 and mixing a beverage using the capsule 11 and its contents.
The dispenser 100 may be configured with additional interface elements not shown in
The base 115 may contain a motor 220 and one or more gears in a gear train 221 or other mechanical devices for effecting movement of components within dispenser 100 (as shown in
In some embodiments, a nozzle array 201 may be attached to the cover 101 as shown in
Additionally, the receiving compartment 108 may comprise a hinged portion 110 to facilitate opening the capsule 11. The receiving compartment 108 may be configured so that when the dispenser 100 is open, the hinged portion 110 is flat, lying in the plane with the rest of the receiving compartment 108, as shown in
A shield 107 may attached to the frame 10 of the dispenser 100 in a position underneath the receiving compartment 108. The shield 107 may be cylindrical in shape and may be wide enough so that the mixed contents of the beverage flowing into a beverage container may not make contact with the inner walls of the shield 107. In this sense, the shield 107 remains clean and avoids contamination. The shield 107 may serve in part as a guide to the user to indicate where a cup or other beverage container should be positioned to receive the mixed contents of the beverage.
The rear housing 103, base 115, cover 101, or another portion of the dispenser 100 may comprise the scanner (e.g., camera, barcode reader, or other sensor) 114 or other sensor as shown in
As shown in
As the cover 101 is lowered into a closed position, hinges 104B, 104C, 104D, 104E are configured to enable the components of the frame 10 to pivot and translate in a concerted folding arrangement to prepare the dispenser 100 and the capsule 11 for beverage mixing. Specifically, the arm 151 connecting hinges 104B and 104C may cause the retractable shield 105 to be pushed up, or retracted, within the cover 101, making space for the dispenser 100 to fully close, at which point the retractable shield 105 is not needed to protect the nozzle array 201 and other internal components.
The arm 152 of the frame 10 connecting hinges 104C and 104D provides the fixture for the anvil 109, and the arm 152 is shaped to position the anvil over the capsule 11 in the receiving compartment 108 when the cover 101 is lowered to a closed position.
The receiving compartment 108 is connected to the frame 10 at hinge 104D, and hinge 104E enables the hinged portion 110 of the receiving compartment 108 to pivot. The receiving compartment 108, including the hinged portion 110, may be configured to move with respect to ramp 208. The ramp 208 may guide the movement of the receiving compartment 108 as the cover 101 is lowered to a closed position so that the capsule 11 placed within the receiving compartment 108 may slide and rotate into a horizontal position for opening.
Additionally, an arm 153 of the frame 10 connecting hinges 104D and 104F anchors the frame 10 to the base 115 of the dispenser 100 via hinge 104F. Hinges 104B-104F enable a folding mechanism to shift and rotate the capsule 11 and other components attached to the frame 10 as the cover 101 is raised or lowered to open or close the dispenser 100, respectively. In other embodiments, different arrangements of hinges and arms may be used. For example, the arm 153 connecting hinges 104D and 104F could be split into two arms connected via an intermediate hinge to permit the receiving compartment 108 additional range of motion. In other embodiments, the nozzle array 201 may be fixed to the base 115 of the dispenser 100, changing or eliminating a need for the retractable shield 105 or the arm 151 connecting hinges 104B and 104C that is shaped to assist with retraction of the retractable shield 105 as the cover 101 is lowered into a closed position.
Furthermore, in some embodiments, a latch 205 may be connected to a portion of the frame 10 via a latch hinge 206. As the frame 10 folds down into a closed position, the latch 205 may hook onto a latch catch 205A positioned on the lowermost arm 154 connected to hinge 104F. The latch 205 may assist with keeping the movement of frame 10 smooth and unified during operations of the dispenser 100 such as the operation for opening the capsule 11 or the operation for rotating the capsule 11 while the beverage is mixed. The latch 205 is configured to release from the latch catch 205A to permit the frame 10 to unfold back up into an open position when the cover 101 is raised. Other alternatives for keeping the movement of frame 10 smooth and unified during operations of the dispenser 100, including causing frame 10 to engage or disengage with gear train 221 using a solenoid or other mechanism, are also contemplated.
(3) Beverage Mixing:
Yet another aspect of the disclosure is the beverage mixing process.
Specifically,
As described previously, in the position shown in
In an exemplary embodiment, the nozzle array 201 has three nozzles: a mixing nozzle 202, a finishing nozzle 203, and a carbonation nozzle 204. The intake of the mixing nozzle 202 may be connected to a mixing fluid source (not shown). The mixing fluid source may provide filtered water or other liquid that is at an ambient temperature. Alternatively, the mixing fluid may be heated or cooled to an optimal temperature for dissolving any powder mixing agents within the capsule 11. In the closed position, the outtake of the mixing nozzle 202 is positioned for directing mixing fluid into the capsule 11 through the opened end of the capsule 11 via a pre-wetting stream or a mixing stream, as described below.
The intake of the finishing nozzle 203 may be connected to a finishing fluid source (not shown). The finishing fluid source may provide filtered water or other liquid that has been chilled or heated to an optimal temperature for drinking the cold or hot beverage of the user's choice, respectively. The same capsule 11 may be used, regardless of whether the beverage is cold or hot. In the closed position, the outtake of the finishing nozzle 203 is positioned for directing finishing fluid directly into a user's beverage container through the shield 107 via a finishing stream. Furthermore, the arrangement of the outtake of the finishing nozzle 203 and the opened end of the capsule 11 is configured to permit the finishing stream to catch and combine with the mixed contents that will flow out of the opened end of the capsule 11. In some embodiments, the arrangement is further configured to create an aesthetically and acoustically pleasing laminar flow that further facilitates additional mixing action within the beverage container as the combined flow of mixed contents and finishing stream enter the beverage container.
The intake of the carbonation nozzle 204 may be connected to a carbonation source (not shown). The carbonation source may provide sparkling water or other carbonation elements that is at an ambient temperature or that has been chilled or heated to an optimal temperature for creating a carbonated beverage. In the closed position, the outtake of the carbonation nozzle 204 is positioned for directing carbonated fluid directly into a user's beverage container through the shield 107 via a carbonation stream. In some embodiments, the arrangement of the outtake of the carbonation nozzle 203, the outtake of the finishing nozzle 202, and the opened end of the capsule 11 is configured so that the carbonation stream cannot interfere with the catching behavior of the finishing stream that is configured to catch the outflow 202C of mixed contents from the opened end of the capsule 11.
As shown in
As shown in
At a snapshot in time (not shown) after the time shown in
In step 550, the capsule 11 may begin rotating under power of a motor or other rotating mechanism of the dispenser 100. In step 560, while the capsule 11 is rotating toward an approximately vertical orientation, a mixing stream may begin being directed into the capsule 11. In step 570, a finishing stream may begin being directed into a beverage container, and a carbonation stream may optionally begin being directed into the beverage container. In embodiments where a carbonation stream is directed into the beverage container, the device may incorporate a carbonation finishing stream dwell time, to allow any rising head of foam to calm down. Additionally, the device may include an additional still liquid finishing stream of higher pressure liquid, to aid additional, further mixing in the beverage container.
In step 580, the mixing stream may be stopped. In step 590, the capsule 11 may reach its nearly vertical orientation and stop rotating as mixed content continues to flow out and combine with the finishing stream to create a laminar flow that proceeds into the beverage container. In step 595, when the capsule 11 is empty or nearly empty, and the mixed content no longer flows out of the opened capsule 11, the finishing stream may be stopped, and the beverage mixing method 500 ends.
While there are many puncture mechanisms that prepare and deliver beverages, the La Vit cracking and peeling mechanism is believed to be a new way to prepare and deliver drinks By exposing the inside of the capsule 11 to a jet of injected mixing stream, the mechanism avoids any build up or clumping of any powder mixing agents on any part of the capsule 11 as the mixture flushes easily out of the capsule 11, allowing a complete and uniform mixing of the substance. When mixing occurs in the capsule 11 and when empty, it is not prone to mildew or bacterial growth like other capsule 11-based systems where the capsule 11 is not flushed.
Commercial applications of the product primarily include the office and home in addition to hospitals, institutions, schools, hotels, cruise boats and any environment where a point-of-use drink machine would be convenient and beneficial.
