Abstract
A variety of liquids in containers can be cooled by a self-contained system for rapidly cooling liquids. A system utilizes cooling devices placed inside, outside, or integrated into containers for liquids. The cooling devices can utilize endothermic or other reactions to rapidly cool the liquids by storing cooling reactants separately and then causing them to mix or react upon demand.
Description
- This application claims benefit of U.S. Provisional Application No. 60/832,759, entitled “Self-Contained System for Cooling Beverages” and filed on Jul. 24, 2006, which is specifically incorporated herein by reference for all that it discloses and teaches.
- The invention relates generally to cooling devices, and more particularly to self-contained systems for rapidly cooling liquids.
- There are many liquids that need to be easily and quickly cooled. For example, in the world of consumable beverages, it is often a requirement that a beverage be cooled before a consumer will enjoy drinking the beverage. There are many methods currently utilized to cool a beverage, including: refrigerating a beverage in a drink cooler or refrigerator, putting a beverage on ice, transferring a beverage to a chilled container, putting ice in a beverage, etc. Perhaps the most common method of cooling a beverage is to place it in a refrigerator and then continuously power the refrigerator, keeping the beverage at a more-or-less constant, cool temperature. Thus, when a consumer purchases the beverage, it is already at the desired cool temperature and ready for consumption. This refrigeration of beverages, however, adds cost to the price of the beverage indirectly through the costs of operating and maintaining refrigerators.
- Once a consumer has purchased a cooled beverage, if the beverage is not immediately consumed, the consumer then must either maintain the cool temperature or the beverage will begin to absorb heat from its surroundings and it will eventually warm to room temperature. Once again, costs are incurred to either maintain the cool temperature of the beverage or re-cool it at some time in the future. If the second option is chosen, there is also a time delay incurred while the consumer must wait for the chosen cooling method to sufficiently re-cool the beverage before consumption can occur.
- One alternative to these problems of maintaining cooled beverages is to simply store the beverages at room temperature and then provide the consumer with a quick-cooling method or device at the time of sale. One example of such a device is a cold water bath that utilizes chilled, rapidly flowing water to draw the heat out of a beverage. However, this point-of-purchase cooling requires the consumer to once again consume the beverage immediately after removal from the water bath or risk allowing the beverage to warm back to room temperature. Furthermore, the cold water bath requires time to sufficiently cool the beverage, it leaves the outside of the beverage container in need of drying, and it must be continually powered in order to be cool and ready to accept beverages upon demand.
- Therefore, there is a need for a rapid liquid cooling device that can be activated at any time and that will cool a beverage or other liquid as desired.
- Embodiments described and claimed herein address the foregoing problems by application of one or more devices that enable a cooling process to be applied to a liquid in a container. The cooling devices may utilize one or more endothermic processes, chemical reactions, combinations thereof, or any other process which results in a net cooling effect. The devices can be contained separately within a container, attached to the outside of a container, or integrated into the structure of the container. Additionally, methods of utilizing the above cooling processes to cool a liquid are described herein.
- Other embodiments are also described and recited herein. Although materials and methods similar or equivalent to those described herein can be used in the practice of the invention, suitable materials and methods are described below. Furthermore, the materials, methods, and examples are illustrative and not intended to be limiting.

The cooling system is a combination of one or more devices and one or more cooling processes integrated into the devices. The device(s) can have various levels of integration into a container that holds a liquid. For example, in one embodiment a device is simply placed inside a container; in another, a device is attached to the inner wall of a container; and in yet another, a device is placed against the outer wall of a container. Other configurations, such as integrating a device into a wall of a container, are also contemplated.

FIG. 1 illustrates an exemplary self-contained system for rapidly cooling a liquid inside acontainer containing liquid 100. Acontainer 101 for liquids is shown. Thecontainer 101 can be of any size and of any shape, including, but not limited to: cylindrical, spherical, cubical, etc. Thecontainer 101 shown inFIG. 1 is of a cylindrical shape similar to that of a standard soft drink beverage container or can.FIG. 1 illustrates a system containing only asingle cooling device 102. - The
cooling device 102 contains afirst unit 103 and asecond unit 104. The units can be compartments, chambers, etc. designed to hold one or more cooling reactants. Other embodiments may have more than two units. Thefirst unit 103 contains one or more cooling reactants. Thesecond unit 104 contains one or more cooling reactants as well. The cooling reactants utilized in any particular embodiment can be selected from any of a number of possible reactants. For example, one embodiment utilizes water as a first cooling reactant and sodium nitrate as a second cooling reactant. As discussed in more detail below, other reactants are contemplated. - Endothermic chemical reactions that can lower the temperature of the liquid beverage in this invention include, but are not limited to, the following reactants reacting with and/or dissolving in water: ammonium nitrate, sodium acetate, acetate salts, sodium nitrate, nitrate salts, sodium thiosulfate, ammonium thiosulfate, thiosulfate salts, calcium chloride hexahydrate, chloride salts, and urea. These reactants may be available in the
first unit 103 or thesecond unit 104 as free solids or as microencapsulated solids. Micro-encapsulation of the salts can be used to control the rate and duration of cooling. Micro-encapsulation entails placing the reactive solid within a slowly dissolving matrix thereby allowing the endothermic reaction with water to be slowed. - Alternative endothermic reactions may also be utilized to achieve cooling of the liquid beverage. These include, but are not limited to, the following: ammonium salt and barium hydroxide, and urea and ammonium chloride. Any other reactions or processes that result in a net reduction in temperature can also be utilized, including gels, phase-changes, etc. There are many net-cooling processes currently known or yet to be discovered in the art and any can be utilized in the present invention.
- Between the
first unit 103 and thesecond unit 104 is aconduit 105. Theconduit 105 provides a means for the reactants in the units to react. In the embodiment described above, water in thefirst unit 103 flows down through theconduit 105 into thesecond unit 104 and reacts with the sodium nitrate to produce an endothermic reaction and cool thecontainer 101 and any liquid inside the container. - The
cooling device 102 can be constructed of any of a number of different materials. In the embodiment show inFIG. 1 , a thin plastic film that is non-permeable is used. Other materials, such as rubber, metal, etc., could make up thecooling device 102 in alternate embodiments. -
FIG. 2 illustrates an exemplary self-contained system for rapidly cooling a liquid attached to acontainer containing liquid 200. The system shown inFIG. 2 is similar to that illustrated inFIG. 1 .FIG. 2 shows acontainer 201 for liquids and acooling device 202. Thecooling device 202 has afirst unit 203 and asecond unit 204. Also, aconduit 205 is shown. In this embodiment, theconduit 205 inFIG. 2 has aseal 206. When initiation of a cooling process or reaction is desired, theseal 206 separates or peels open and theconduit 205 allows reactants in thefirst unit 203 andsecond unit 204 to mix. In alternate embodiments, a valve or other method can be utilized to control the flow of reactants through the conduit in place of aseal 206. - In addition, a
non-peelable perimeter seal 207 is illustrated inFIG. 2 . Theperimeter seal 207 is used in this embodiment to attach thecooling device 202 to thecontainer 201. In alternate embodiments, no seal is necessary as thecooling device 202 may not be attached to thecontainer 201. - The
first unit 203 is shown inFIG. 2 as having a left non-peelable,anti-inflation seal 208 and a right non-peelable,anti-inflation seal 209. Thesecond unit 204 is shown inFIG. 2 as having a left non-peelable,anti-inflation seal 210 and a right non-peelable,anti-inflation seal 211. These anti-inflation seals are similar to theperimeter seal 206 in that they are used in this embodiment to attach thecooling device 202 to thecontainer 201. However, the anti-inflation seals also serve another purpose: they ensure that thefirst unit 203 and thesecond unit 204 remain in place against the side of thecontainer 201 instead of changing shape and/or location. -
FIG. 3 illustrates a side cross-sectional view of an exemplary self-contained system for rapidly coolingliquids 300.FIG. 3 shows acontainer 301, and acooling device 302 having afirst unit 303 and asecond unit 304 as well as aconduit 305 separated from thefirst unit 303 by aseal 306. As can be seen from comparing the placement of theseal 306 inFIG. 3 to theseal 206 inFIG. 2 , placement of the seal in various locations relative to theconduit 305 and theunits single seal 306 shown inFIG. 3 . - In the upper portion of the
first unit 303, an activatingagent 320 is illustrated above afirst cooling reactant 340. The activatingagent 320 shown in this embodiment is a nitrogen gas. Other activatingagents 320 are contemplated. Thefirst cooling reactant 340 shown in this embodiment is a liquid, preferably water. Once again, other cooling reactants are contemplated. Thesecond unit 304 is illustrated containing asecond cooling reactant 350. In one embodiment, a dry chemical makes up thesecond cooling reactant 350. - There are a number of ways in which the
seal 306 can be peeled open, including, but not limited to: the activatingagent 320 forcing the seal open using pressure, the activatingagent 320 forcing the seal open using a mechanism, etc. In the embodiment shown inFIG. 3 , the activatingagent 320 is a nitrogen gas. The liquid 330 in thecontainer 301 is under pressure from carbonization. This pressure holds theseal 306 closed against the force exerted by the activatingagent 320 and, by extension, thefirst cooling reactant 340. However, once thecontainer 301 is opened, the carbonation pressure is reduced, thus allowing the pressure exerted by the activatingagent 320 and thefirst cooling reactant 340 to peel open theseal 306 allowing the mixing of thefirst cooling reactant 340 with thesecond cooling reactant 350 through theconduit 305. - It should be noted that during a manufacturing process to construct the components show in
FIG. 3 , various difficulties may arise. For example, beforecarbonated liquid 330 is added to thecontainer 301 containing thecooling device 302 and thecontainer 301 is sealed, the pressure exerted by the activatingagent 320 could peel open theseal 306. In order to prevent this, a small clamp hinged on one end and cemented together on the other can be attached over theseal 306. Food grade cement can be used to hold the clamp closed. When the liquid 330 is added to thecontainer 301 and thecontainer 301 is sealed, the cement can then dissolve in the liquid 330 and thereby release the clamp and prepare theseal 306 to be peeled open when thecontainer 301 is subsequently opened. Other possible clamping or temporary sealing methods can be utilized including any of the many methods currently employed in the art or yet to be discovered. -
FIG. 4 illustrates a side cross-sectional view of an exemplary self-contained system for rapidly cooling liquids that utilizes a mechanical activating agent which is in the closed state.FIG. 4 shows acooling device 402 having afirst unit 403 and asecond unit 404 as well as aconduit 405 separating thefirst unit 403 from thesecond unit 404 by aseal 406. Placement of theconduit 405 in various locations relative to theunits single conduit 405 shown inFIG. 4 . - The
first unit 403 and thesecond unit 404 shown inFIG. 4 form two halves of a spherical-shapedcooling device 402. The shape of thecooling device 402 can be a cube, cylinder, or any other workable shape in other embodiments. Furthermore, alternate embodiments can have more than two units containing reactants, with one or more conduits between them. - In the
first unit 403, an activatingagent 420 is illustrated. The activatingagent 420 shown in this embodiment has ahead 421, aplunger 422, and aspring 423. Theplunger 422 rests in a hole in the top wall of thefirst unit 403. Connected to the bottom of theplunger 422 is theseal 406. Theseal 406 appears in the example illustrated inFIG. 4 as a cylinder attached to the bottom of theplunger 422. Theseal 406 extends through a hole in theconduit 405 that is aligned with the hole in the top wall of thefirst unit 403 such that theplunger 422 and the attachedseal 406 can slide up and down through the two holes. The diameter of theplunger 422 and the hole in thefirst unit 403 should be such that theplunger 422 fits tightly within the hole to prevent the contents of thefirst unit 403 from leaking out. The diameter of theseal 406 and the hole in theconduit 405 should be such that theseal 406 seals tightly against the hole in theconduit 405 to prevent the contents of thefirst unit 403 from leaking into thesecond unit 404, and vice-versa. Theplunger 422 as shown in this illustration is of a cylindrical shape, other shapes are contemplated. - As shown in this embodiment, the
head 421 attaches to the top of theplunger 422 and rests outside thefirst unit 403. Thehead 421 can be any suitable shape that prevents theplunger 422 from completely entering thefirst unit 403. Furthermore, when thehead 421 is in contact with the outer surface of the top wall of thefirst unit 403, the two form a second seal that prevents the contents of thefirst unit 403 from escaping out of thefirst unit 403 or anything that is outside thefirst unit 403, such as a liquid to be cooled, from invading thefirst unit 403. - The
spring 423 is shown inFIG. 4 as surrounding and fitting over theseal 406 attached to the bottom of theplunger 421. Alternate placements are contemplated. As shown inFIG. 4 , thespring 423 provides a downward tension that holds thehead 421 in contact with the outer surface of the top wall of thefirst unit 403. And, since theplunger 422 is connected to the head and theseal 406 is connected to theplunger 422, the spring holds theseal 406 in the hole in theconduit 405 and seals thefirst unit 403 from thesecond unit 404. When a force is applied to thehead 421 and thehead 421 is pulled up and away from thefirst unit 403, theplunger 422 pulls on theseal 406 and theseal 406 is pulled up and out of the hole in theconduit 405, allowing the contents of thefirst unit 403 and thesecond unit 404 to mix. In an alternate embodiment, a change in the external pressure pushing against the cooling device 401 can be used to move thehead 421,plunger 422, andseal 406. -
FIG. 5 illustrates a side cross-sectional view of an exemplary self-contained system for rapidly cooling liquids that utilizes a mechanical activating agent which is in the open state.FIG. 5 shows acooling device 502 having afirst unit 503 and asecond unit 504 as well as aconduit 505 separating thefirst unit 503 from thesecond unit 504 by aseal 506. Placement of theconduit 505 in various locations relative to theunits single conduit 505 shown inFIG. 5 . - In the
first unit 503, an activatingagent 520 is illustrated. The activatingagent 520 shown in this embodiment has ahead 521, aplunger 522, and aspring 523. Theplunger 522 rests in a hole in the top wall of thefirst unit 503. Connected to the bottom of theplunger 522 is theseal 506. Theseal 506 appears in the example illustrated inFIG. 5 as a cylinder attached to the bottom of theplunger 522. Theseal 506 extends downwards towards a hole in theconduit 505 that is aligned with the hole in the top wall of thefirst unit 503 such that theplunger 522 and the attachedseal 506 can slide up and down through the two holes. Since the activatingagent 520 is shown open or activated inFIG. 5 , theseal 506 is slid into the up position and does not rest in the hole through theconduit 505. The diameter of theplunger 522 and the hole in thefirst unit 503 should be such that theplunger 522 fits tightly within the hole to prevent the contents of thefirst unit 503 from leaking out. The diameter of theseal 506 and the hole in theconduit 505 should be such that theseal 506 seals tightly against the hole in theconduit 505 to prevent the contents of thefirst unit 503 from leaking into thesecond unit 504, and vice-versa. Theplunger 522 as shown in this illustration is of a cylindrical shape, other shapes are contemplated. - As shown in this embodiment, the
head 521 attaches to the top of theplunger 522 and is outside thefirst unit 503. Thehead 521 can be any suitable shape that prevents theplunger 522 from completely entering thefirst unit 503. Furthermore, when thehead 521 is in contact with the outer surface of the top wall of thefirst unit 503, the two form a second seal that prevents the contents of thefirst unit 503 from escaping out of thefirst unit 503 or anything that is outside thefirst unit 503, such as a liquid to be cooled, from invading thefirst unit 503. Even when thecooling device 502 is in the open or activated position, as shown inFIG. 5 , the second seal remains intact and the liquid to be cooled can not invade thefirst unit 503. - The
spring 523 is shown inFIG. 5 as surrounding and fitting over theseal 506 attached to the bottom of theplunger 521. Alternate placements are contemplated. As shown inFIG. 5 , thespring 523 provides an upward tension that acts to push thehead 521 away from the outer surface of the top wall of thefirst unit 503. And, since theplunger 522 is connected to the head and theseal 506 is connected to theplunger 522, the spring tension acts to push theseal 506 out of the hole in theconduit 505. In the embodiment shown inFIG. 5 , an external pressure—that of the carbonated liquid to be cooled—presses against thehead 521 and counteracts the spring tension, holding theseal 506 in place in the hole in theconduit 505. When the container holding the carbonated liquid to be cooled and thecooling device 502 is opened, a reduction in the external pressure that is holding thehead 521 against the outer surface of the top wall of thefirst unit 503 causes the tension in thespring 523 to be able to overcome the pressure holding thehead 521 against thefirst unit 503. Thespring 523 extends, pushing theplunger 522 up through the hole in thefirst unit 503 and the attachedseal 506 up and out of the hole in theconduit 505, allowing the contents of thefirst unit 503 and thesecond unit 504 to mix. The illustration inFIG. 5 shows thecooling device 502 in this opened or activated state. As detailed above, a food grade cement that dissolves in liquids can be used during the manufacturing process to keep the head cemented to thefirst unit 503 until the container is sealed. Other possible clamping or temporary sealing methods can be utilized including any of the many methods currently employed in the art or yet to be discovered. - The descriptions above illustrate exemplary components that can make up a cooling system. In addition, the acts of creating the components; integrating them in, out, or into a container; opening the container; and causing the cooling to occur are another aspect of this invention.
- The technology described herein can be described as methods and/or actions in one or more systems.
