Description

Humidification and dehumidification method and apparatus for cooling beverages and other foods, and manufacturing method

The novel invention relates generally to techniques for cooling food and beverage food containers and methods for making such food containers. More specifically, the present invention is a food and beverage food container for cooling food such as beverages; A method of cooling the food; And a method of assembling and operating the device. The terms "beverage", "food", "food" and "food container contents" are considered equivalent for the purposes of this application and are used interchangeably. The term "food container" means any openable sealed storage means for food to be consumed.

There have previously been many self-cooling beverage food container devices for cooling the contents of a beverage or other food and beverage food container. Such devices sometimes use flexible deformable receptacles or rigid receptacle sides to store refrigerant for phase change cooling. Some prior art devices use a desiccant with vacuum activated to evaporate water at low pressure and absorb the vapors into the desiccant. Other conventional devices use refrigerant stored between pressure vessels in the liquid phase to achieve cooling by causing a phase change of the refrigerant from liquid to gaseous state. The inventors have invented these various devices and methods of manufacturing them. Several previous self cooling food container technologies rely on the evaporation of refrigerant from the liquid phase to the gas phase. Some rely solely on the desiccant. Desiccant technology relies on the thermodynamic potential of the desiccant to absorb water from the gaseous phase into the desiccant, causing evaporation of water in vacuum. These early inventions do not meet all the needs of the beverage industry and do not use electromotive heat transfer means to cool the beverage. In fact, since they are structurally very different from the present invention, those skilled in the art cannot move from the prior art to the present invention without a creative process. The inventors have carried out various experiments to find a cost-effective and functional device for self-cooling beverage food containers to arrive at a new method at present. The next problem has greatly suppressed the cost-effective commercialization of all prior art devices.

Prior art using liquefied refrigerants does not solve the real problems of manufacturing and beverage plant operations critical to the success of self-cooled food container programs. Some of these prior art configurations require pressurized food containers to store liquid refrigerant. The only liquid refrigerants that can be stored between commercially viable pressure canisters are HFCS, CFCS, hydrocarbons, ethers and other highly flammable low pressure gases. These gases are not commercially viable and have led to difficulties in the implementation of this technology. Most commercial refrigerants have been banned as products in self-cooled food containers by the US EPA and other regulatory agencies for direct emissions to the atmosphere due to ozone depletion and global warming. The EPA stipulates that the refrigerant is not used in self-cooled food containers, except for CO ₂ , and the configuration must be safe when used. Currently available refrigerants cause global warming and ozone depletion. Generally, these are common refrigerants such as 134a and 152a. In some cases, flammable gases such as butane and propane have been tried, but risk factors are high for a number of reasons. First, the use of these technologies in confined spaces can have various effects such as suffocation and addiction. Second, the flammability of some refrigerants limits the number of food containers that can be opened in a closed environment, such as during a party or in a vehicle. The inventors have several patents on these prior art, and after testing several of these technologies, they found that they were not suitable for commercial practice. In addition, the cost of refrigerant is a large deterrent, and the cost of cooling cannot justify the use of refrigerant gas.

Examples of inventions using pressurized gas are U.S. Patent Nos. 2,460,765, 3,494,143, 3,088,680, 4,319,464, 3,241,731, 8,033,132, 4,319,464, 3,852,975, 4,669,273, 3,494,141, 3,520,148, 3,636,58,446,3,971,468,437,654,5848,937,446,452 5,655,384, 5,063,754, 3,919,856, 4,640,102, 3,881,321, 4,656,838, 3,862,548, 4,679,407, 4,688,395, 3,842,617, 3,803,867, 6,170,283, and 5,704,222.

Prior art using cryogenic refrigerants such as CO ₂ do not solve the real problems of manufacturing and beverage plant operations critical to the success of self-cooled food container programs. All of these prior art configurations require pressurized food containers to store cryogenic refrigerants. Some technologies promising the use of CO ₂ have implemented fullerene nanotubes and carbon traps such as activated carbon to store the refrigerant in a carbon matrix. These added desiccants and activated carbon storage systems are too expensive for commercial implementation, and pressure-lowering carbon and other absorbent media can contaminate beverage products. Therefore, there is a need to reduce the amount of these chemicals required. Cryogenic self-cooling food containers that require the use of ultra-high pressure containers and cryogenic gases such as CO ₂ require expensive food containers made of materials that withstand high pressures such as aluminum, steel or fiberglass. The pressure involved is inherently dangerous as it is typically above 600 psi. In addition, they are complicated because the pressures involved are much higher than what conventional food containers can withstand. Examples of such prior art include the devices disclosed in US Pat. No. 5,331,817, US Pat. No. 5,394,703 to the inventor, US Pat. Nos. 5,131,239, and 5,201,183 and US Pat. No. 4,993,236.

Desiccant-based self-cooling food containers require the desiccant to be stored between pre-made vacuums. When the vacuum is released between the two compartments, water vapor enters the vacuum and is then absorbed by the desiccant and the heat of evaporation is taken from the cooled item and carried to condense in the desiccant. The heat taken up by the evaporated water heats the desiccant and should not interact with the beverage. Otherwise, the beverage will heat up again. It is very difficult to maintain a true vacuum in the desiccant chamber and water reservoir. In addition, valves and activation devices used in the prior art require stiff pins, knives, and the like. The vacuum must be maintained for long periods of time during storage and can sometimes fail. Cooling capacity can be impaired if moisture moves to the desiccant. Also, it is very difficult to process the desiccant crystals in a way that implements prior art designs, and it is very difficult to process the powder in a mass production environment where the desiccant must be kept free of moisture and contaminants inside a pressurized beverage food container. . Therefore, better techniques are needed to handle these desiccants separately from food containers. In addition, as the vacuum becomes and evaporation begins, the heat absorption potential of the desiccant decreases, making the process itself inefficient and limited to the amount of desiccant used.

Problems posed by vacuums, including the difficulty of creating and maintaining vacuums, and the lack of efficiency they can produce, have also arisen in other fields. An early example can be found in Thomas A. Edison's Pre-Evolution. His first practical incandescent lamp, patented in 1879, contained carbonized bamboo filaments within a vacuum glass bulb. This almost certainly led the world to a new era, but at first it was very inefficient. Next, in 1904, European inventors replaced the carbonized bamboo filaments with tungsten, and in 1913 it was discovered that replacing the vacuum inside the bulb with an inert drying gas doubled the luminous efficiency. This field is different from the current one, and the technical problems presented are quite different, but this is perhaps a case that evokes the idea of improving product efficiency by replacing vacuum with dry gas.

In general, this prior art is not a cost effective technique and relies on a very large and complex canister configuration with respect to the beverage food container contained therein. In fact, the ratio of desiccant to water is about 3:1 and the volume loss ratio of such a beverage container is about 40%. The desiccant or adsorbent cost, food container cost, and manufacturing process cost are too expensive despite nearly 20 years of effort. Therefore, it is advantageous to reconfigure the manufacturing process to reduce the amount of ingredients required and to separate the interior of the food container from these chemicals.

Examples of devices using this technology are U.S. Patent Nos. 7,107,783, 6,389,839, 5,168,708, 6,141,970, 829,902,4, 462,224, 7,213,401, 4,928,495, 4,250,720, 2,144,441, 4,126,016, 3,642,059, 3,950,379,025, 736,472,379,025, 2759,472 3.25227 million, 3,967,465, 1,841,691, 2,195,0772, 322 617, 5168708, 5230216, 4.91174 million, 5,233,836, 4.75231 million, 4,205,531, 4.04881 million, 2,053,683, 3,270,512, 4,531,384, 5,359,861, 6.14197 million, 6341491, 4993239, 4901535, 4949549, 5048301, 5079932, 4513053, 4,974,419, 5,018,368, 5,035,230, 6,889,507, 5,197,302, 5,313,799, 6,151,911, 6,151,911, 5,692,381, 4,924,676, 5,038,581, 4,479,364, 4,368,624, 4,660,874,629, 4,574,230,629, 4,574,230,629, 4,574,232 U.S. Patent No. 5,983,662 uses a sponge instead of a desiccant to cool beverages.

The prior art also shows chemically endothermic self-cooled food containers. It relies on using a fixed stoichiometric reaction of the chemical to absorb heat from the food container contents. U.S. Patent Nos. 3,970,068, 2,300,793, 2,620,788, 4,773,389, 3,561,424, 3,950,158, 3,887,346, 3,874,504, 4,753,085, 4,528,218, 5,626,022, and 6,103,280, and many other patents use an endothermic reaction to cool beverage containers from water to cool beverage containers Let it.

Previous endothermic self cooling food containers rely on a fixed amount of a stoichiometric mixture of chemicals to achieve a fixed amount of cooling. After the cooling process, the thermodynamic transfer mechanism and cooling potential are depleted and no further cooling can occur. In addition, the reaction products remain corrosive and acidic components in the form of bases and acids, which can be harmful. For example, US Patent Application Publication No. US2015/0354885AL discloses a system for externally cooling a beverage containing a certain amount of beverage. The system includes a cooling housing having an inner wall and an outer wall, the inner wall consisting of a thermally conductive material in contact with at least a portion of the beverage holder, the cooling housing defining an inner compartment containing at least two distinct substantially non-toxic reactants. do. When reactants react with each other, an irreversible, entropy increasing reaction produces a product that is substantially non-toxic with a stoichiometric number that is at least three times greater than the stoichiometric number of the reactants, the at least two distinct substantially non-toxic. The reactants are initially contained in the inner compartments separated from each other, and when reacting with each other in the irreversible entropy increasing reaction, cause a decrease in heat of the beverage in the beverage holder. Although no recovery system is used to save the stoichiometric ratio of reactants, this system belongs to the same type of endothermic system disclosed in all prior art that uses a fixed cooling potential based on a fixed stoichiometric ratio of the reactants. . Further cooling using electromotive heat transfer means is not disclosed.

The present invention is different from all the prior art mentioned, a new cost-effective, thermodynamically simple and viable heat transfer means for cooling beverages in food containers by renewing the cooling potential of a fixed amount of reactants using mechanical regeneration of dry gas. Provides. Many tests have been performed and many designs have been made to obtain the present configuration of the disclosed invention.

No. 7,107,783.

1.0 Defects in prior art using endothermic cooling systems

a) Endothermic cooling systems of the prior art have a limited potential to induce cooling after solvation, for example because the solvation energy of the ionizable compound used is generally dependent on the temperature of the solvent such as water. Water acts as a humidifying liquid that ionizes chemicals, and ions supplement the solvation energy, and as the solvent cools, the process becomes insufficient in energy, which slows down the solvation energy extraction process exponentially. Does not use all of the available solvation energy potential. For example, to cool a 16 ounce beverage by 30° F., it is necessary to dissolve at least 127 grams of potassium chloride in about 380 grams of water. This is not commercially viable for self-cooling food container technology that relies solely on this process. The present invention overcomes these deficiencies with extremely dry gases. Dry gas with a dew point of 10 to -150° F. can easily absorb vapors from liquids cooled to freezing point. The drying gas simply raises the dew point temperature, while the actual thermometer temperature of the drying gas itself remains constant.

b) Also, the stored solute used for endothermic cooling in a solvent such as water requires a stoichiometric molar ratio with water for cooling. In all prior art, a fixed amount of cooling can be achieved by irreversibly combining a fixed amount of water with a fixed amount of ionizable compounds (eg, chloride and nitrate). The solvated products of the endothermic reactants can result in acidic solutions and basic products such as hydrochloric acid and sodium hydroxide obtained by dissolving potassium chloride ions in water. This deficiency forces this transition of water from a liquid state to a vapor state from a cold solution to dry the compound, offsets the stoichiometric ratio of water to the compound used, and cools again by allowing more water to be solvated. In the compartment formed by the inner sleeve member with a possible protrusion, it is solved by the drying gas, which acts as an intermediary to renew the reaction of increasing entropy in an irreversible manner. The protrusion allows one side of the inner sleeve member to hold the humidifying liquid and the other side of the inner sleeve member to act as a dry gas evaporator. The drying gas removes the heat of reforming this solute from the solution. This has the advantage of regenerating an ionizable compound that can be re-ionized reversibly for an endothermic reaction by a desalting and salting process that can only occur with a dry gas acting as an intermediate vehicle for evaporation.

c) In addition, the prior art requires a desiccant and impermeable metal used in the water chamber because it is necessary to maintain a true vacuum over a long period of time. In the present invention, aluminum can be used in the construction of the device according to the present invention, but the parts of the device surrounding food are preferably heat-shrinkable, such as injection stretch blown polyethylene tetraphthalate (PET) and shrinkable polyvinyl chloride (PVC). Made of plastic material, it is an inexpensive material that interacts with standard aluminum or steel food containers. The implementation of these materials allows these materials to perform mechanical functions when subjected to evaporation heat, and by means of the heat-shrinkable physical properties of the material, the volume of the drying gas chamber is to produce a leanening of a fixed volume of drying gas in the drying gas chamber. By increasing the r, you actually do mechanical work from this heat.

d) Also, since the food container itself is not deformed in a breakable manner, the manufacturing process of the food container is not affected by the method used to manufacture the device.

Thus, the present invention bypasses the stoichiometric limitations of common methods of cooling products by endothermic reactions, and also bypasses the need for a true vacuum and other deficiencies, as well as the properties of the materials used, acting in a beneficial manner. Using dry gas at low vapor pressure with a dew point temperature in the range of Fahrenheit to -150 Fahrenheit, it is transferred directly to the properties of the electromechanical steam and heat transfer means.

2.0 Defects in prior art using desiccant/vacuum cooling systems

a) Previous desiccant technology had to store a permanent true vacuum to evaporate and cool the water at low pressure. The present invention bypasses this step of storing vacuum in the desiccant process and takes advantage of the physical properties of the material used by the present invention to produce a dilution of the drying gas only when necessary. The drying gas starts the evaporation process, and the evaporation process is enhanced by the dilution of the drying gas. In most cases, the material used to make the present invention is preferably made of a combination of heat shrinkable plastic materials such as injection stretch blown heat shrinkable polyethylene tetraphthalate (PET) and heat shrinkable polyvinyl chloride (PVC), It is an inexpensive material that interacts with standard aluminum or steel food containers. The implementation of these materials allows them to perform a mechanical function when subjected to the heat of evaporation, and by expanding the volume of the drying gas chamber to create a dilution of the drying gas by the heat-shrinkable physical properties of the material. To get things done. Aluminum can be used in many parts of the construction, but certain features used for thinning of the drying gas require such heat-shrinkable plastic materials.

b) Further, the prior art desiccant process creates a 100% partial vapor pressure of the evaporator such as water in the cooling chamber when the vacuum is exposed to the cooling chamber. This presents a problem. The water vapor evaporated by the vacuum reduces the vacuum and stops the process until the desiccant again begins to reduce the vapor pressure in the cooling chamber. Thus, the process depends on the rate of vapor absorption by the desiccant.

c) In addition, the water vapor evaporated by the prior art vacuum fills the cooling chamber, contacts the cooling surface and is condensed to transfer heat of condensation from one section of the cooling chamber to another. The minimum operating temperature for evaporated steam is 32°F, which is the freezing point of water. The drying gas system used by the present invention has a dew point temperature in the range of 10[deg.] F. to -150[deg.] F. below the freezing point of water, so that the evaporation of water vapor into the dry gas is not hindered by cooling and freezing. The drying gas dew point temperature is raised by evaporation, but does not heat the cooling chamber.

d) Also, during the absorption reaction, the absorption heat can heat the absorbent material and the absorption to water is significantly reduced. The drying gas becomes more hygroscopic as it is heated by taking heat from the vapor absorber to lower the dew point temperature.

In the present invention, plastic heat shrink vapor absorber technology is used by some embodiments of the present invention. The drying gas is used to absorb the humidified liquid vapor from the compartment made by the inner sleeve member which can be at an ice-cold temperature while lowering the dew point temperature of the drying gas (not the temperature of the drying gas). Unlike prior art conventional desiccant systems, this humidified liquid vapor is not readily available to the cooling surface for condensation. The humidified liquid vapor is maintained by the low vapor pressure of the drying gas and therefore does not condense again on the cooling surface. The plastic heat shrink vapor absorber absorbs vapor from the drying gas, thus eliminating the need for a true vacuum. Thus, any humidifying liquid can be used. For example, a humidifying liquid such as dimethyl ether, which is a pressurized liquid, can be used, but can emit vapors that can be immediately absorbed by the drying gas. In a sense, the drying gas acts as a locomotive vapor pressure cascade conductor to transfer the vapor from the liquid phase to the plastic heat-shrink vapor absorber using its electromotive potential. As long as the vapor is not exposed to the cooling chamber, the vapor is absorbed by plastic heat-shrink vapor absorbers that interact more readily with the mechanical properties of the drying gas than direct vapor. For example, standard desiccants in air conditioners using desiccant wheels are used to transfer moisture and regenerate using the benefits provided by drying gases. This is not done in vacuum. It is conceivable that the drying gas has a gap van de wall force that holds the vapor in the form of a hermetically sealed gap more suitable for plastic heat-shrink vapor absorbers to absorb the vapor. Molecular sieves with small pore sizes have been shown to be able to absorb vapors more easily in dry gas than they absorb directly. This can be explained by recognizing that polar vapor molecules tend to be electrically bonded to form cascade chains towards low vapor pressure regions and thus exhibit a fluid-like viscous behavior that depolarizes the molecules. The polarity of a humidifying liquid, such as water, is what is needed to drive the desiccant absorption process. This can be seen as the double formation of ordinary gases such as h ₂ , n ₂ , o _2, etc. in non-polar gases. The drying gas inhibits this polarity, thus the normal static electricity associated with the drying air, from driving the process electrostatically.

The present invention is a plastic heat-shrink vapor absorber chamber wall specially configured to deform the shape to generate and generate leanness by increasing the volume of the dry gas chamber in which a fixed amount of dry gas is stored, using the heat of the plastic heat shrink vapor absorber. Activates the physical properties of Therefore, there is no need to store a permanent vacuum, and no true vacuum is required.

In addition, as an added advantage, the present invention uses a simple deformable seal comprising a sealing ring structure composed of one of a suitable O-ring seal, metal band seal, rubber band seal, putty seal and sealing wax seal to trigger operation and In the present invention, a pin, a knife, and other methods may be used to introduce water vapor into the plastic heat-shrinkable vapor absorber because it performs a sealing function, but it is not necessary. No worries about vacuum loss during storage. As such, the plastic heat shrinkable vapor absorber and the subcategory of vapor absorber used in the present invention need not necessarily have the best affinity for the humidification liquid vapor of the humidification liquid used. Instead, they are optimized for the delivery of the humidified liquid vapor by dry gas. Thus, while the prior invention requires fine tuned desiccants for pure vapor absorption, the present invention fine tunes the vapor absorber for vapor absorption from the dry gas.

Dry gases such as substantially dry air, substantially dry CO ₂ , substantially dry nitrogen and other substantially dry gases with very low dew point temperatures are subject to weather patterns driven primarily by the humidity of the air and the thermal energy available in the atmosphere. It can cause severe cooling, as evidenced by Naturally, dry air can lead to dramatic snow and ice formation, leading to extreme weather patterns worldwide. It's not surprising that lip balms used for dry lips are selling well in winter. From hurricanes to tornadoes to snow storms to icy winter storms, nature provides an amazing means of electromotive heat transport, which helps to cool beverages and food using the humidification and dehumidification of the air. Can be imitated. My theory is that the tremendous vacuum energy of the tornado is the result of the sudden condensation of water vapor due to the dehumidification of the humidified dry air. Water vapor is 1840 times the volume of liquid water of the same weight, so when a huge cloud condenses, the volume decreases enormously, resulting in a vacuum that looks like a tornado's funnel cloud. Simple wind motion cannot generate this enormous amount of energy. Likewise, humidification of very dry air results in very cold temperatures that result in blizzards. This occurs when moisture is absorbed by dry air and evaporates to remove heat from the surrounding environment, followed by saturation of the same moist air that accumulates again as moisture in cold environments such as snow and hail that occur in the cold environment. .

Water has the best thermodynamic potential for cooling food. Water has the highest heat of evaporation, and as such, it can be used to cool food containers, with a mechanical drying and regeneration process that also depends on water molecules. However, water does not evaporate easily due to the high heat of evaporation and must be "induced" to evaporate by suitable means. In addition, it becomes increasingly difficult to evaporate water as it cools, for example in endothermic reaction and desiccant evaporation systems. Therefore, the endothermic cooling of the prior art or the conventional desiccant cooling system by itself does not prove to be the most efficient form of cooling food products such as beverages. The combination of dry gas mediated and other cooling methods can effectively increase the thermodynamic potential of cooling food products using two basic substances, water and dry gas.

The seal breaking structure may also be inwardly as a recess made in the food container side wall, but preferably the seal breaking structure may be provided with a thick self-adhesive plastic strip attached to serve as an obstruction of the smoothness of the food container side wall. A seal breaking structure is provided in order to interfere with the sealing made by the dry gas seal of the side wall of the food container.

The cover sleeve member seal is provided in the form of one of a ring structure made of one of an O-ring seal, a rubber band seal, a putty seal and a sealing wax seal, and an adhesive binder, and is formed in the form of a thin loop. In the case of rubber bands, this is the type commonly used when holding multiple objects together, such as a stack of paper. In the case of O-rings, this is a type of rubber seal that is commonly used for sealing purposes between surfaces. The cover sleeve member seal preferably surrounds the food container side wall with a cross-sectional dimension of less than 4 mm. Preferably the cover sleeve member seal is expandable to form an airtight sealing band around the food container. When made of sealing wax, a cover sleeve member seal must be formed on the food container side wall in an appropriate position as defined herein. For example, in the case of one of rubber band and O-ring, the loop diameter of the cover sleeve member seal is expandable, and the cover sleeve member seal is parallel to the diameter plane of the food container and close to the food container upper wall. It is arranged in a circumferential direction to keep airtight around the top wall seam of the container.

The dry gas seal is again provided in the form of one of an O-ring seal, a rubber band seal, a putty seal and a sealing wax seal, a ring structure made of an adhesive bond, and is formed in the form of a thin loop. The dry gas seal should have a cross-sectional dimension surrounding the side wall of the food container and preferably less than 4 mm in width. If the dry gas seal is a rubber band, it expands to form a band around the side wall of the food container. If made of sealing wax, a dry gas seal should be formed on the side wall of the food container in a suitable location. The dry gas seal is disposed circumferentially to maintain an airtight seal around the side wall of the food container in a plane angled to the diameter plane of the food container when a rubber band is used. The minimum distal separation of the dry gas seal under the cover sleeve member seal is preferably about 20 mm.

Before the device is used, a seal breaking structure is placed between the dry gas seal and the cover sleeve member seal.

An inner sleeve member is provided, and in a first embodiment, the inner sleeve member is preferably made of a thin material such as plastic and aluminum, and the inner sleeve member wall is a cotton laminated to the inner sleeve member wall, woven. It has a wicking material made of one of mesh, absorbent paper and absorbent cardboard. Preferably the inner sleeve member is made of a thin plastic material and is formed by compression molding, heat shrinking and injection molding.

The inner sleeve member has an inner sleeve member sidewall having an inner surface and a surface protrusion on the outer surface, such as the protrusions shown in Figs. 2, 12, 20, 21 and 22. These protrusions may be in the shape of a waveform including an inward protrusion and an outward inward protrusion. The purpose of inward protrusions and outward protrusions to increase strength, surface area makes it possible to:

a) Various distinct compounds may be stored between the outward protrusions when forming a compartment against the sidewall of the food container. More discrete compounds can be stored between the inward protrusions when forming the compartment for the cover sleeve member.

b) The humidifying liquid can be pulled between the protrusions to ionize and cool the compound. The drying gas can also freely pass through the compartment to evaporate the humidifying liquid.

c) Reactive chemicals that react endothermally can be stored between separate compartments before being allowed to mix and react by modifying the compartments.

Uniform corrugated protrusions of the inner sleeve member are shown in Figs. 2, 12, 20, 21 and 22, which are only examples of possible protrusions that can be made on the inner sleeve member sidewall. For example, the inner sleeve member side wall can be injection molded to have ribs protruding from the wall to form a partition that realizes the same purpose. Various protruding shapes, such as the protrusions described above, can be used to increase the surface area of the inner sleeve member. For example, the inward protrusion of the inner sleeve member is tangentially matched with the side wall of the food container to form an outward compartment composed of an outward protrusion around the side wall of the food container to receive the compound and humidification maintained in the outward compartment formed with the side wall of the food container. Liquid enters the interior, dissolving endothermally and ionizing the compound which provides the first cooling of the product. Thereafter, the humidifying liquid, preferably water, can be evaporated by the drying gas present in the outward section and absorbed by the plastic heat-shrink vapor absorber to provide a second cooling means. The opposite configuration is also possible when the compound is held between the outward projections with respect to the food container sidewall and the humidifying liquid is held between the outwardly inwardly outward projections and enters between the outwardly outward projections causing endothermic cooling by solvation.

The inner sleeve member may also be made of a cylindrical wall with protrusions that provide structural support and also retain the solution and allow free passage of the drying gas to evaporate the humidification liquid in the drying gas chamber. Preferably, the inner sleeve member is a heat-shrinkable plastic sleeve having a wicking material attached to the surface to retain sufficient humidification liquid by osmotic pressure without absorbing and leaking the humidifying liquid.

In a first embodiment, the inner sleeve member at least partially circumferentially surrounds the food container side wall in the area under the dry gas seal, and is held in place by friction with the food container side wall using one of an adhesive or tape. Preferably, the inner sleeve member extends to partially cover the exposed surface of the side wall of the food container under the dry gas seal and surround the lower edge of the food container as a cup-like structure.

A cover sleeve member is provided which is preferably made of one of heat-shrinkable polyethylene terephthalate (PET) and polyvinyl chloride (PVC) to form a heat-shrinkable thin-walled cup-shaped sleeve that surrounds all or part of a food container. Preferably, the cover sleeve member has a cover sleeve member sidewall that can take on various shapes, but should have a cylindrical sealing portion such that it can be hermetically mated with a portion of the food container sidewall as described in the subsequent paragraphs and pages. .

The cover sleeve member side wall is the outer cover of the device, covering the entire inner sleeve member and the sealed food container containing food under the food container upper wall, partially covering the inward wall of the drying gas chamber and partially covering the humidifying liquid chamber wall. Partially formed. The side wall of the cover sleeve member is preferably made of a plastic material such as heat-shrinkable PET and heat-shrinkable PVC, and the heat-shrinkable PVC can be partially deformed by heat shrinkage when heat is applied to this part. The cover sleeve member sidewall may preferably extend to partially cover the food container sidewall and partially cover the food container upper wall. The cover sleeve member sidewall is fitted to cover and surround the inner sleeve member. Since the inner sleeve member has an outward protrusion in tangential contact with the inward surface of the cover sleeve member sidewall, it forms a part of the drying gas chamber that can have a plurality of compartments formed by the inward protrusion together with the cover sleeve member sidewall. .

When the cover sleeve member side wall is extended to cover most or all of the top wall of the food container, an extension grip made of a simple plastic ring is added and snapped to the food container top wall seam, allowing the user to hold the extension grip and rotate it relative to the cover sleeve member. To be able to rotate the food container. As shown in Fig. 17, the cover sleeve member can be constructed with support structures such as channels and cavities that allow it to have more structural strength to prevent collapse when vacuum is applied.

The cover sleeve member side wall covers the attached inner sleeve member, and covers the food container wholly or partially. The cover sleeve member side wall has a cover sleeve member seal that is shrinkable in diameter to form a seal and can be heat contracted to seal against the food container side wall. It is expected that the cover sleeve member side wall end will be located in the cover sleeve member seal, but it is contemplated that the cover sleeve member side wall end may extend beyond the cover sleeve member seal. When the cover sleeve member seal is heat-shrinkable, the cover sleeve member side wall applies pressure around the surface of the cover sleeve member seal on the food container side wall and clamps it, and also applies pressure around the surface of the dry gas seal on the food container side wall. And clamp it to form a humidification liquid chamber between the side wall of the food container and the side wall of the cover sleeve member.

As described above, the cover sleeve member is rotatable relative to the side wall of the food container. Thus, advantageously, the dry gas seal and the cover sleeve member seal are rotated together with the cover sleeve member relative to the food container side wall. It is contemplated that the cover sleeve member sidewalls are deformed by compressive heat shrinking around the cover sleeve member seal to provide for holding the cover sleeve member seal firmly and sealingly rotating with the cover sleeve member. However, the cover sleeve member may be spun-shaped and then made of thin aluminum which may be formed to hold the cover sleeve member seal firmly and the cover sleeve member seal is sealed together with the cover sleeve member. It is envisaged that it may be provided to be rotated. It is expected that the cover sleeve member side wall is partially deformed by compression around the dry gas seal to keep the dry gas seal firm, and that the dry gas seal is provided to rotate sealingly with the cover sleeve member relative to the food container side wall. . However, it is envisaged that the cover sleeve member can be made of thin aluminum that can be spun-formed to hold the cover sleeve member seal firmly and that the cover sleeve member seal can be provided to rotate sealingly with the cover sleeve member. . The cover sleeve member seal is arranged symmetrically with respect to the rotational force of the cover seal and may not rotate with the cover sleeve member, but it is nevertheless expected to form a seal between the cover seal and the food container side wall. However, since the dry gas seal is not symmetric with respect to the rotation of the cover sleeve member, it is expected that the dry gas seal should rotate with the cover sleeve member relative to the food container sidewall.

The cover sleeve member sidewalls are either heat-shrunk (if made of heat-shrink PET or heat-shrinkable PVC) or crimped and spin-formed using a roller (if made of aluminum) as described above for the cover sleeve member seal. Can be compressed and sealed together. The cover sleeve member sidewalls can be reinforced by protrusions, such as ribbing, corrugation, and circumferential grooving, to provide strength, surface area and allow various ionizable compounds to be stored between the inward protrusions. And allow easy passage of dry gases and vapors. The cover sleeve member side wall has a cover sleeve member seal that is used to form a sealing surface with a cover sleeve member seal. When the cover sleeve member seal is retracted to seal against the dry gas seal, it presses against the food container sidewall to form a fluid seal. When the cover sleeve member seal is retracted and clamped and sealed on the surface of the dry gas seal, it forms a rotatable seal between the food container sidewall and the cover sleeve member. It is contemplated that the cover sleeve member seal partially deforms around the cover sleeve member seal to provide it to hold the cover sleeve member seal securely and to provide it to rotate sealingly with the cover sleeve member. It is contemplated that the cover sleeve member side wall partially deforms around the dry gas seal to hold the dry gas seal firmly and, when rotated, provide it to rotate sealingly with the cover sleeve member. This provides an actuation means when the cover sleeve member is rotated.

Partially the inward surface of the cover sleeve member side wall, the dry gas seal, the cover sleeve member seal, and partly the outward surface of the food container side wall together form a humidification liquid chamber. The humidification liquid is hermetically stored between the humidification liquid chambers. It is envisaged that the humidifying liquid may also be a pressurized liquefied gas.

The cover sleeve member sidewall has a cover sleeve member restriction that is clamped against a wick on the inner sleeve member to form a vapor passage that is restricted to allow humidification liquid vapor and drying gas to pass through in a controlled manner. The inner sleeve member restricting portion forms a restricted vapor passage rotatable when clamped around the surface of the wick. It is envisaged that the cover sleeve member sidewall rotates in a sliding manner over the limited vapor passage when rotated without deforming or rotating the limited vapor passage and the inner sleeve member itself. The cover sleeve member is made of a cover sleeve member lower wall sealingly connected to the cover sleeve member sidewall. The cover sleeve member lower wall is preferably rotated so as to be hermetically connected to the inwardly protruding cover sleeve member annular wall forming a truncated cone shape. The cover sleeve member annular wall may also take other forms such as a partially hemispherical dome shape, a cylindrical shape and an inverted truncated cone shape, ie it may have a larger closed end diameter at the top wall than the open end. The drying gas chamber is a chamber formed inside the cover sleeve member under the drying gas seal.

Accordingly, according to the first embodiment of the present invention, the drying gas chamber is below the humidified liquid chamber and includes an attached inner sleeve member and a food container. It is contemplated that the cover sleeve member may be made of spun or deep drawn aluminum, which may be formed to provide all the sealing required by spin forming and rolling in part. In this case, the cover sleeve member annular wall can be made of one of a heat-shrinkable injection stretch blown PET and polyolefin material and a PVC material, and then can be bonded to the cover sleeve member lower wall by ultrasonic welding or adhesion.

A thin walled open end support cylinder having a support cylinder hole close to the upper end is disposed at an opposite open end on the lower wall of the cover sleeve member between the cover sleeve member side wall and the annular wall of the cover sleeve member and is arranged to contact the lower edge of the food container.

The annular plastic heat-shrink vapor absorber holding space is defined in the drying gas chamber between the inner surface of the support cylinder, the surface of the annular wall of the cover sleeve member, and the inner surface of the lower wall of the cover sleeve member. An annular thermal wax holding space is also defined in the drying gas chamber between the outer surface of the support cylinder and the inner surface of the cover sleeve member annular wall and the inner surface of the cover sleeve member lower wall. The annular thermal wax holding space may optionally be filled with a suitable thermal wax that melts at a temperature in the range of 70° F. to 160° F. The support cylinder prevents the cover sleeve member lower wall from collapsing with respect to the food container and deforming its shape, and also protects the user's hand holding the device from excessive heat. The thermal wax 138 can be removed and replaced with a drying gas.

Several cooling operating means and cooling operating means steps are provided. The first silver starts when the cover sleeve member is rotated relative to the side wall of the food container, which is placed on the sealing destruction structure provided with the drying gas seal and the drying gas seal, and is in fluid communication between the humidifying liquid and the drying gas chamber exposed from the humidifying liquid chamber. Makes it possible. A second cooling operation means and a second cooling operation means step are also provided. The deformable ring structure seal, preferably made of one of O-ring seals, metal seals, rubber band seals, putty seals and sealing wax seals, adhesive binders and formed in the form of a thin loop, forms a dry gas seal, and is a deformable material. Is preferred. When the cover sleeve member is pressed onto the dry gas seal to deform its shape, the humidifying liquid may leak out of the humidifying liquid chamber and enter the dry gas chamber to ionize the compound and evaporate it into a dry gas. Good results are also obtained when the dry gas seal is made of a deformable structure such as a thin metal band layered with a sealing wax material or a sealing putty material.

The inner sleeve member is preferably made of protrusions defining the sidewalls of the food container and also the sidewalls of the cover sleeve member to provide strength, surface area, and allow various distinct compounds to be stored between the protrusions.

The annular plastic heat-shrinkable vapor absorber holding space maintains a plastic heat-shrinkable vapor absorber such as silica gel and the absorber shape described in Table 1. The annular plastic heat-shrinkable vapor absorber holding space is an extension-molded heat-shrinkable portion of the cover sleeve member. If the cover sleeve member is made of aluminum, the annular wall of the cover sleeve member should be made of a separate item made of one of heat-shrinkable PET and heat-shrinkable PVC and should be attached to the lower wall of the cover sleeve member with an appropriate adhesive. The cover sleeve member annular wall reacts to temperature rise by deformation and contraction and planarization to increase the volume of the drying gas chamber. This deformation is caused by heating the plastic heat-shrink vapor absorber while absorbing the humidified liquid vapor from the drying gas.

The cover sleeve member annular wall preferably forms a shape that penetrates into the volume of the drying gas chamber. The protruding shape of the annular wall of the cover sleeve member is important to improve the function of the device. The shape of the cover sleeve member annular wall can be any suitable shape that minimizes the volume of an equivalent cylindrical volume formed by an inverted cup, a dome, and preferably a cover sleeve member sidewall having a flat bottom. The shape of the annular wall of the cover sleeve member should initially minimize the volume of the drying gas chamber and maximize the intrusion into the drying gas chamber when it is next heated. In the embodiment shown in the figure, the shape of the annular wall of the cover sleeve member forms an inverted cup-like shape and a dome. Advantageously, the annular plastic heat shrink vapor absorber holding space is in fluid communication with the drying gas. When the device cooling operating means is activated, the plastic heat-shrinkable vapor absorber heats the cover sleeve member annular wall. When heated, the cover sleeve member annular wall contracts and minimizes its area. The annular plastic heat-shrink vapor absorber holding space is contracted and moved outward from the domed lower wall of the food container. This lowers the partial vapor pressure of the drying gas and of the humidification liquid vapor in the drying gas chamber and thus the inner sleeve member.

The inner sleeve member may also be made of one of pressure molded aluminum and deep drawn aluminum. It is envisaged that the inner sleeve member sidewall may be formed with a layer of wicking material made to remain intact when receiving the humidifying liquid. The inward protrusion and the outward protrusion may be formed by first making the inner sleeve member sidewall into a cylinder, and then placing the cylindrical wall on a mold to heat-shrink to form an inward protrusion and an outward protrusion. Preferably, the inward protrusion tangentially abuts the food container sidewall and the outward protrusion forms a plurality of compartments with the food container sidewall to retain the compound or humidifying liquid on the food container sidewall. The outward protrusion also contacts tangentially to the cover sleeve member sidewall and the inward protrusion forms a plurality of compartments with the cover sleeve member sidewall to allow fluid communication with the drying gas.

It is contemplated that in all embodiments, the walls of the inner sleeve member walls may also be impregnated or layered with an ionizable compound having a reversible endothermic entropy increasing reaction with the humidifying liquid. The inner sleeve member can be heat-shrunk to form a shape by hot spraying with a stream of particles of an ionizable compound at a high impact pressure when heat-shrinkable to shape on a mold. In all cases, the inner sleeve member should only have a vapor passage formed by the outer surface wall and the cover sleeve member side wall to allow vapor to pass through the plastic heat shrink vapor absorber. This is easily achieved by banding the vapor wicking material over the inner sleeve member restriction when the film material forms the inner sleeve member.

Another method of inserting the ionizable flexible salt into the inner sleeve member is the use of a flexible material such as polyvinyl acetate (PVA) layered on the outer wall of the inner sleeve member, and then the ionizable compound is added to the PVA layer. And attaching to. Other laminating materials such as water-soluble adhesives can be used for this purpose. The drying gas is preferably provided to the drying gas chamber just below ambient atmospheric pressure.

Extremely dry gases such as dry air and dry CO ₂ are provided. The drying gas can be stored at room temperature and at an appropriate pressure. Dry gases can be easily prepared by removing humidified liquid vapors from wet gases using a pressure precipitation system and cooling system or desiccant stack. When the drying gas is stored in the drying gas chamber, it acts as if the drying gas chamber is emptied for the purpose of the humidifying liquid introduced into the drying gas chamber. This is because the drying gas has a humidified liquid vapor pressure low enough to be called a vacuum partial humidified liquid partial vapor pressure. In a closed food container, the drying gas is cooled by absorbing the humidified liquid vapor from the surrounding environment in the same way that water evaporates when exposed to a vacuum when exposed to the humidified liquid vapor. However, the drying gas does not allow easy condensation of the humidified liquid vapor on the surface above the dew point temperature because it carries the humidified liquid vapor as electrostatically bound vapor within the molecular structure. This boils down to a means of heat transfer that can be understood by comparing the relationship of temperature to pressure with what happens to the exhausted gas. The drying gas has the constituent molecules of moisture that can only apply a partial humidification liquid vapor pressure, and its vapor acts as if it were in a vacuum. This interstitial molecular sieve of the potential of the dry gas is a measure of the relative dew point temperature for a humidified liquid vapor such as a gas exhausted at a negative temperature in relation to the wet gas at room temperature. Since the partial vapor pressure of the humidified liquid vapor in the drying gas is very low, the moisture behaves as if suspended in a vacuum when exposed to the drying gas. Thus, all operations performed by the drying gas in the practice of the present invention are, except for the fact that the vacuum environment evaporates the humidification liquid and the humidification liquid vapor can condense on a surface cooler than the temperature of the vapor. It is equivalent to the action that occurs in the exhausted environment for steam. Dry gas is an electric vehicle. This is justified by the fact that the drying gas acts as a clearly distinct unit of vibrational mechanical energy or as a phonon with both. Phonons and electrons are the two main types of elementary particle excitation that are the centers of thermal energy that contributes to heat capacity. The removal of polar humidified liquid vapor molecules, such as water molecules in vapor form, into dry gas is due to the mechanistic heat transfer potential. Dry gas respiration enhancement (hyperpnoea) is known to change airway reactivity and ion content in rabbit organs (refer to respir physiol. 1997 jul;109 (1):65-72). In a paper titled "Characteristics of gas ions" (nature 95, 230-231 (29 April 1915) doi:10.1038/095230b0), the negative ions of dry gas are generally transitional steps for a certain range of electric forces and pressures. Finally, it is shown that the cathode carriers are molecular clusters that become virtually all electrons. In the book "Electrical conduction through gas" (Cambridge University Press), the excess of the rate of anion diffusion than the rate of diffusion of cations causes the gas to become humid. It is shown that it is much larger when it is dry than when it is dry. Thus, the drying gas is an electromotive heat transfer means. Therefore, the essential drying gas is better than vacuum with respect to the evaporation of the humidifying liquid, especially if the relative dew point of the drying gas to the humidified liquid vapor is in the lower range than the formation of solids from the humidified liquid. The humidification liquid vapor pressure is low. In the case of water vapor, this is less than 32°F. In polymeric membranes (PEMs) such as Nafion®, a hydrophobic Teflon-like backbone is used with sulfone end groups attached to the mechanistic transport moisture through the membrane. Polyvinyl acetate (PVA) containing a membrane is also used for the purpose of filtering ions from the solution. The vapor pressure of the humidified liquid vapor varies stepwise in these chemicals, creating a flow, for example, as the dry molecules of Nafion® pull the humidified liquid vapor deeper through its structure by mechanical heat transfer. The drying gas behaves in a similar manner as above by creating a spherical gradient of the drying gas to carry the humidified liquid vapor and equilibrating the vapor pressure of the humidified liquid vapor.

The potential to remove a humidifying liquid such as water from the drying gas can result in a dew point of 10°F to 150°F. Thus, any humidifying liquid above this temperature tends to be absorbed by the drying gas below the dew point temperature. This potential for drying gases and a specially designed wicking layer to absorb the humidification liquid from the cold surface is utilized in several cooling processes to allow for much more efficient cooling, which can otherwise be achieved by vacuum or stoichiometric endothermic reactions with desiccants. It is possible to create a continuous process that results in For example, it is necessary to dissolve at least 127 grams of potassium chloride in about 380 grams of water using existing prior art techniques to cool a 16 ounce beverage by 30[deg.] F. This is not commercially viable for self-cooling food container technology that relies solely on this process. The present invention can use much less ionizable compound (67 g) with 100 g of humidifying liquid in one mode and regenerate the ionizable compound for reuse. For example, ion exchange compounds and other types of electrochemical and electromechanical membranes, such as PEM, are preferentially cooled by absorbing water vapor and transferring protons through the structure to convert the liquid into the delivered vapor. The inner sleeve member may be made of a similar material, such as an ion exchange film material, to deliver water formed by the reaction of chemicals in the humidification liquid chamber and act in a similar manner to be further cooled. The drying gas in the drying gas chamber may interact several times with the humidification liquid vapor in the drying gas chamber to be humidified and further cooled.

Given a beverage mass of m _b and a heat capacity c _p , the heat removed to bring about a temperature change of Δt is given by

To produce water with a relative humidity ratio x = 0.02, the amount of water evaporated in the area exposed to the drying gas at the same temperature as the water with a starting humidity ratio x _s = 0.005 (kg of H ₂ O per kg of dry gas) /sec) is given by an empirical formula (the 2003 Ashrae handbook-HVAC Applications, Ashrae 2003, Shah 1990, 1992, 2002):

Where θ = (25 + 19v), v is the velocity of the gas flow.

As an example using dry gas, the practical calculations are approximate for 1 m/sec of air flow for 45 seconds at a starting relative humidity of 0.005 and an exposed area of about 225 cm ² (6"x 6" cooling matrix). It is shown that the rate of water removal is equal to 0.158 g/sec. The total heat required to raise 7.8 g of water into steam from a room temperature of 22 °C is given by the drying gas as follows:

Here, E _h is the energy used to heat water, and E _v is the energy required to evaporate water at 100°C.

This means 17,615 joules of energy per cooling matrix removed only by the drying gas. Only 54,790 joules of energy are needed to cool 453 g (16 liquid ounces) of beverage from room temperature to 20°C. Thus, if endothermic action does not occur, only two (2) second wicking layers may be needed in the cooling matrix, although more could be added. It is clear that there are many thermodynamic potentials stored between the drying gases for heat removal. Dry air, CO ₂ and nitrogen have very similar thermodynamic behavior during the humidification process. Thus, dry air is not an advantageous gas that can be used for this purpose. A suitable extreme dry gas such as dry CO ₂ is sufficient as long as the dew point can be properly lowered to accommodate thermodynamically.

WW Mansfield in Nature (205, 278 (January 16, 1965), DOI: 10.1038/205278A0) under the title "Effect of carbon dioxide on evaporation of water". Published research, and titled "Influence of gases on the rate of evaporation of water" by Frank Sechrist (199, 899-900, August 31, 1963). A study published as a study shows that water containing dissolved carbon dioxide or surrounded by the atmosphere of this gas evaporated 15% to 50% faster than water in the presence of air alone. Thus, advantageously, the use of a drying gas such as CO ₂ already found in carbonated beverages can certainly increase the cooling capacity of the drying gas in water.

The present invention is different from all the prior art mentioned, and is made of bottles and cans (metal and plastic beverage food containers) in a label-like structure with the additional aspect of using a vapor-mechanical heat transfer means to gradually cool the beverage by several means. Introducing a new technology for cooling. Now the manufacturing cost is limited only by the cost of the cover sleeve member, the cost of the inner sleeve member, the cost of the chemical composition and the process cost used to manufacture the device.

The drying gas can also transport water vapor from the cold solution during the electrolytic invasion process to dehydrate this ionic solution and cause the solute to reactivate to use more of its thermodynamic potential. The drying gas will not only cool, but the stoichiometric imbalance of solute reuse will allow further cooling to be performed. The invention can only be practiced with dry gas and dry gas chambers without chemicals. For example, a humidifying liquid can be produced by a chemical reaction of water to provide a hydrated chemical in a dry gas chamber. This resulting humidification liquid can be further cooled by being evaporated and absorbed by the drying gas. In addition, the plastic heat-shrink vapor absorber keeps the drying gas dry in the drying gas chamber. The humidified liquid vapor absorbed by the drying gas can be absorbed by the plastic heat-shrink vapor absorber to lower the vapor pressure in the humidifying liquid chamber and cause further evaporation and cooling of the humidifying liquid held between the inner sleeve member and the food container side wall, which is then Cool food.

The removal of the humidified liquid vapor absorbed from the wet drying gas by the plastic heat shrink vapor absorber allows the drying gas to be refreshed again and used again without the need to put a large amount of drying gas in the drying gas chamber. Thus, the present invention has several advantages in method and function over the evaporation, endothermic and desiccant-vacuum systems disclosed in the prior art.

Second embodiment of the present invention

A second embodiment of the present invention is shown in Figs. 11, 12 and 20. In the second embodiment of the present invention, the same elements used in the first embodiment are used to reconfigure the method of operation and use of other devices. At this time, the drying gas seal is disposed to move further downward to seal between the inward surface of the side wall of the cover sleeve member and the outward surface of the lower edge of the side wall of the inner sleeve member. Accordingly, the inner sleeve member, the drying gas seal, the cover sleeve member seal and the food container portion form a humidification liquid chamber. The humidifying liquid is retained in the highly hydrated reaction compound. Thus, the humidifying liquid is instead released by the reaction of a reactive compound having an endothermic reaction that turns water into a humidifying liquid. The drying gas chamber is formed under the drying gas seal separated from the humidified liquid chamber. In this embodiment of the present invention, the reactive compound is stored between the two sides of the inner sleeve member in a compartment formed by the food container side wall having an outward protrusion of the inner sleeve member. The reactive compound may also be stored outside the inner sleeve member sidewall in a compartment defined by the cover sleeve member sidewall having an inwardly protruding portion of the inner sleeve member.

The humidifying liquid is used to fill the partition formed between the side wall of the food container and the outward projection of the inner sleeve member.

A fourth embodiment of the present invention is shown in FIG. 16. In the fourth embodiment of the present invention, the same elements used in the first embodiment are used to reconfigure different methods of operation and use of the device. In the fourth embodiment of the present invention, the dry gas seal is again moved over about half of the inward surface of the inner sleeve member side wall, and the inward surface of the inner sleeve member side wall upper edge and the inward direction of the food container side wall as in the second embodiment. Seal between surfaces. The humidification liquid is filled in the compartment formed under the dry gas seal between the inward surface of the outward projection of the inner sleeve member and the outward surface of the side wall of the food container. This allows the soluble compound to be filled in the compartment formed between the outward surface of the side wall of the food container and the inward surface of the outward protrusion of the inner sleeve member over the dry gas seal.

It is an object of the present invention to use a new heat transfer means to remove heat from food using dry gas as an ion modifier that modifies a solute from ions in a solution to its original nonionic state that is reused several times for the same purpose. It is to provide a way to cool the container.

Finally, it is an object of the present invention to provide a thermodynamically simple, feasible, and cost-effective device for removing heat from food and cooling food accordingly.

The present invention achieves not only the above-mentioned objects but also other objects, as can be determined by fair reading and interpretation of the entire specification.

Thus, the present invention can achieve even more cooling, including:

a) remove water vapor from the cold solution and evaporate to increase cooling;

b) dehydrating the compound ionized with the negative entropy of the solution back to its original ionizable compound state and reused for further cooling (preservation of the ionizable compound);

c) removing the heat of evaporation from the cold solution and removing the reversible reforming energy of the compound from the ionic solution to prevent reheating by reversing the heat of formation of the ions from the solution;

d) Using dry gas to evaporate water vapor from the reaction product water to remove more heat and to clean the vapor for further cooling.

e) By the deformation of the annular plastic heat-shrink vapor absorber holding space, the drying gas is automatically leaned to increase the volume of the drying gas chamber, induce the leaner of the drying gas, and reduce the partial vapor pressure of the drying gas to reduce the evaporation of the humidification liquid. To further increase.

Heat transfer means

The first heat transfer means disclosed in the present invention uses a substantially dry gas as a medium for regenerating the ionic state from a solution of a humidifying liquid and a solute that forms ions for reuse. This achieves the following:

a) cooling by ionization of a compound soluble in the humidifying liquid entering the drying gas chamber;

b) In the reversible salting of the humidification liquid, the drying gas that depletes the solvent of the solution by reconstitution and modification of the ionizable compound, and the regenerated demineralization solute to re-ionize, cool and repeat the cooling cycle are reused in the drying gas chamber. Additional cooling by drying solutes that achieve more reuse by reusing with more humidification liquid entering.

c) Further cooling by evaporation of the humidification liquid of (a) or (b) by dry gas.

The humidifying liquid is preferably water, and may also be a liquid having an ionization potential for an ionizable compound or solute.

The deposition of a solute by a dry gaseous medium such as a dry gas increases the dew point temperature without heating and removes the heat generated by desalting as a humidified dry gas. Therefore, there is no need to store the stoichiometric ratio of a solvent such as a humidifying liquid and an ionizable compound such as an ionizable compound to cool the beverage. Humidifying liquids may exceed ionizable compounds, and ionizable compounds are ionized several times through multiple mineralization and desalting cycles. When the solvation rate and desalination rate of these solutions are controlled, the drying gas removes the humidification liquid from these reactions at a controlled rate to regenerate the solute for further solvation and essentially does not reheat the cooling surface, and this water vapor for reuse. Will carry. The ions release the same energy absorbed from the humidified liquid ions that are broken. The efficiency lies in the direct transfer of binding energy from the humidified liquid molecules broken into the reforming energy of the humidified liquid vapor as vapors that are immediately transported or absorbed and removed by dry gas humidification. An embodiment using water is shown.

If the product is a liquid with water, a large amount of the product itself can function as a humidifying liquid such as water if it does not react inversely with the solute. If the product is semi-solid or solid, a separate liquid is provided which is preferably simply a suitable humidifying liquid.

A food container is provided comprising a food container having a discharge port and a discharge port opening means. The food container is preferably one of a metal can and a plastic bottle. The drying gas is preferably provided with one of air, nitrogen and carbon dioxide. The drying gas preferably has a dew point temperature of less than 10° F. with respect to the humidified liquid vapor.

The humidified liquid chamber is sealed at the center of the inner sleeve member side wall by a dry gas seal. It is shown that a finger depresses the dry gas seal and causes the humidifying liquid to enter the dry gas chamber in a manner similar to that shown in FIG. 15. The flow of the humidification liquid from the humidification liquid chamber is due to the pressure difference between the drying gas chamber and the humidification liquid chamber. When the plastic heat shrinkable vapor absorber is heated to deform the annular plastic heat shrinkable vapor absorber holding space, it creates a negative pressure in the drying gas chamber. This draws the humidification liquid from the humidification liquid chamber to the drying gas chamber, saturating the drying gas chamber and causing both endothermic cooling and evaporative cooling.

(123) It is possible to cover and surround the entire food container side wall 100 from below, and it is expected that the inner sleeve member lower wall 106 extends to cover and surround the food container domed lower wall 22 as a cup-shaped sleeve structure. . The inward protrusion 103 and the outward protrusion 104 must be rigid and must prevent the inner sleeve member sidewall 105 from collapsing under reduced pressure.

A cover sleeve member 30 is provided. The cover sleeve member 30 is preferably from one of a heat-shrinkable material of stretch-molded polyethylene terephthalate (PET), polyvinyl chloride (PVC), and other heat-shrinkable material and also surrounds all or part of the food container 20.

The cover sleeve member lower wall 130 is hermetically connected to the cover sleeve member shrinkable annular wall 133 protruding inward. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding.

The cover sleeve member inner surface partially defines a space formed by the cover sleeve member lower wall 130 and the cover sleeve member shrinkable annular wall 133 and a drying gas chamber (DGS) extending to cover the inner sleeve member.

It is envisaged that the cover sleeve member 101 may be made of one of spun aluminum, hydraulically formed aluminum and deep drawn aluminum to provide all the necessary sealing. In this case, the cover sleeve member shrinkable annular wall 133 may be made of one of heat shrinkable PET and PVC materials and may be added to the cover sleeve member lower wall 130 by ultrasonic welding or bonding. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding.

As shown, the thin walled open end support cylinder 132 having the support cylinder hole 137 close to the upper end is a cover sleeve member between the cover sleeve member sidewall 101 and the cover sleeve member shrinkable annular wall 133 Arranged to lie on the lower wall 130 and to act as a support member for the cover sleeve member lower wall 130 against the food container 20 to prevent retraction forces from collapsing the cover sleeve member lower wall 130 Can be.

It is formed between the spaces defined by the surface. The annular plastic heat-shrink vapor absorber holding space 131 is in fluid communication with the drying gas and is in the drying gas chamber DGS. The annular heat wax holding space 136 is a drying gas chamber (DGS) between the outer surface of the support cylinder 132 and the inner surface of the cover sleeve member shrinkable annular wall 133 and the inner surface of the cover sleeve member lower wall 130 Is also formed. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding. The annular thermal wax holding space 136 may be optionally filled with a suitable thermal wax 138 that can be melted at a temperature in the range of 70° F. to 160° F. to control the amount of heat exposed to the cover sleeve member shrinkable annular wall 133. I can. The support cylinder 132 prevents the cover sleeve member lower wall 130 from collapsing and deforming its shape relative to the food container 20.

The cover sleeve member 30 is rotated together with the dry gas seal 123, and the dry gas seal 123 crosses over the sealing destruction structure 122, and between the food container side wall 100 and the cover sleeve member side wall 101 A cooling operation means θ is provided when breaking the seal formed by the dry gas seal of and exposing the humidifying liquid HL from the humidifying liquid chamber W into the dry gas chamber.

The inner sleeve member 102 is preferably composed of an inward protrusion 103 and an outward protrusion 104 as shown in FIGS. 2, 12, 13 and 20 to surround the food container side wall 100 To form a pattern. In this case, the inward protrusion 103 will abut the food container side wall 100 and the outward protrusion 104 will abut the cover sleeve member side wall 101. This increases the strength and surface area, and various reaction compounds (RCC) that undergo an endothermic reaction and soluble compounds that dissolve endothermic (DCC) are stored in a state isolated from each other in each chamber formed between the protrusions as shown in FIG. Allow to be. It is expected that each wave form will endothermicly dissolve and function as a storage means for a separate compound (S) that cools.

The cyclic plastic heat-shrinkable vapor absorber holding space 131 holds a plastic heat-shrinkable vapor absorber D such as silica gel, molecular sieve, clay desiccant such as montmorillonite clay, and calcium oxide and calcium sulfide. The annular plastic heat shrinkable vapor absorber holding space 131 is preferably stretch-formed by one of thermoforming, injection-expansion-blowing and vacuum molding when the cover sleeve member 30 is formed. The cover sleeve member shrinkable annular wall 133 increases the volume of the drying gas chamber DGS in response to an increase in temperature due to deformation and thus dilutes the drying gas contained therein. This deformation is heated when the plastic heat-shrink vapor absorber (D) absorbs the humidification liquid (HL) vapor from the humidified drying gas (DG) in the drying gas chamber (DGS) to heat the cover sleeve member shrinkable annular wall 133. It is caused by The drying gas chamber (DGS) is in fluid communication with the plastic heat-shrink vapor absorber (D) and the limited vapor passage (129a), and thus advantageously, the annular plastic heat-shrink vapor absorber holding space 131 is in fluid communication with the drying gas chamber (DGS). In communication and within the inner sleeve member 102. When the cooling operation means θ is activated, the plastic heat shrinkable vapor absorber D heats the cover sleeve member shrinkable annular wall 133. The cover sleeve member shrinkable annular wall 133 protrudes and enters into the drying gas chamber DGS. The shape of the protrusion is important in improving the cooling performance of the device. The shape of the protrusion formed by the cover sleeve member retractable annular wall 133 can be an inverted cup, dome, and preferably any suitable shape that minimizes the volume of the drying gas chamber (DGS). The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding.

The shape of the cover sleeve member shrinkable annular wall 133 should minimize the drying gas chamber DGS and maximize intrusion into the drying gas chamber DGS. In the illustrated example, the shape of the protrusion formed by the cover sleeve member shrinkable annular wall 133 is an inverted cup-like shape and a dome. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding. When heated, the cover sleeve member contractible annular wall 133 contracts and minimizes its area. The annular plastic heat-shrink vapor absorber holding space 131 expands outward to increase its volume, and the volume of the dry gas chamber (DGS) is maximized, preferably lower than the initial pressure, which is just below atmospheric pressure. To create a substantially lower pressure in the drying gas (DG). This lowers the vapor pressure of the drying gas (DG) and any humidified liquid vapor (Vw) in the drying gas chamber (DGS).

The inner sleeve member 102 is preferably made of a plastic material such as PET and PVC. When made of a non-plastic material, the protrusion of the inner sleeve member 102 is formed by a water-insoluble adhesive added to the wicking material to form the inner sleeve member 102 and then the material is desired as the adhesive dries. Molded into shape. The inner sleeve member 102 can hold the humidifying liquid against the food container side wall 100 when the humidifying liquid HL is accommodated, and also an outward protrusion capable of holding the compound S against the food container side wall 100 It is expected that it could be made to have 104.

In order to form the inwardly protruding portion 103 and the outwardly protruding portion 104, the material used to make the inner sleeve member 102 is placed on a mold, so that if it is made of a heat-shrinkable material, it is heat-shrinkable, if it is made of a plastic material. It is formed by either injection molding and, when made of a wicking material, press forming with an adhesive. Thus, the inner sleeve member 102 may have an inwardly protruding portion 103 and an outwardly protruding portion 104, which, when bounded by the food container sidewall 100, dissolve not only liquid but also endothermicly to A separate compound (S) can also be maintained, which can be either cooled by plum and cooled by endothermicly creating a humidifying liquid. It is contemplated that the inner sleeve member 102 may also be formed from a moldable wicking material such as cotton to which a dry insoluble adhesive has been added.

A cardboard 134 bonded to cover the cover sleeve member lower wall 130 to act as an insulator and protect the consumer from possible burns due to the heat generated by the plastic heat shrink vapor absorber (D) is optionally provided but required no. The cardboard 134 must be breathable and preferably has a small cardboard hole 135 to allow free flow of gas to and from the atmosphere when the annular plastic heat shrink vapor absorber holding space wall 133 is flat. .

In all embodiments, it is expected that the wall and the interior of the material of the inner sleeve member 102 may be implanted with the humidifying liquid HL and the ionizable compound S having a reversible endothermic reaction. This can be accomplished by laminating the walls of the inner sleeve member 102 with an ionizable salt such as potassium chloride, ammonium chloride and ammonium nitrate, and another type of endothermic salt having an endothermic ionization potential. When made of a heat-shrinkable plastic material such as PET and PVC, the inner sleeve member 102 is ionizable by hot spraying at high impact pressure with a particulate stream of ionizable compound (S) to heat shrink and form on the mold. By coating with the compound (S), it can be heat-shrunk to form a final shape. In all cases, the inner sleeve member 102 has a limited vapor passage 129a as described below that only allows the humidification liquid vapor Vw to pass through the plastic heat-shrink vapor absorber D of the drying gas chamber DGS. It has a wick on the outer surface to be formed. This is easily achieved by banding the wicking material over the inner sleeve member restriction 128 when the plastic film material forms the inner sleeve member 102.

Another method of inserting an ionizable flexible compound (S), such as an endothermic salt, into the material of the inner sleeve member 102 is the step of using a layer of polyvinyl acetate (PVA) on the outer wall of the inner sleeve member 102 and then And attaching the ionizable compound (S) to the PVA layer. Other laminating materials such as humidifying liquid (hl)-soluble adhesives can be used for this purpose.

The drying gas DG is preferably provided inside the drying gas chamber DGS just below ambient atmospheric pressure. The drying gas GS is provided by the drying gas source DGS, and fills the space between the plastic heat-shrink vapor absorber D and the inner sleeve member 102 in the drying gas chamber.

Manufacturing method of the first embodiment

The manufacturing method M of the device is described herein as shown in FIGS. 18 and 19. This manufacturing method (M) is generally applied to all embodiments except for some sequence of operations that may be changed or removed as necessary. A standard food container 20 is provided. A cover sleeve member seal 121 is provided, the cover sleeve member seal 121 being parallel to the diameter plane of the food container 20 and around the food container side wall 100 in a plane close to the food container upper wall seam 114 It is placed tightly in a sealing manner in the circumferential direction.

The dry gas seal 123 is provided as a rectangular seal such as a rubber band and is expanded and disposed on a plane inclined in the circumferential direction at a small angle with respect to the diameter plane of the food container side wall 100, and the cover sleeve member seal 121 ) Has a maximum separation of about 50 mm below and a minimum separation of about 20 mm. Preferably, a plastic self-adhesive label forming the seal breaking structure 122 is provided, such that the food container side wall () to be placed inside and between the maximum separation distance between the dry gas seal 123 and the cover sleeve member seal 121 100).

An inner sleeve member 102 is provided and is attached in a circumferential direction to at least partially cover the food container side wall 100 under the dry gas seal 123 using one of friction, adhesive and double-sided adhesive tape.

The cover sleeve member 30 is provided as a cup-shaped structure having a straight cover sleeve member side wall 101 as shown in FIG. 2. The cover sleeve member side wall 101 must be at least 50 mm longer than the food container 20 and extend beyond the food container top wall 107. The cover sleeve member sidewall 101 is fitted upward to cover and surround the inner sleeve member 102.

The support cylinder 132 is disposed to be seated on the lower wall 130 of the cover sleeve member having the support cylinder hole 137 close to the food container 20, and holds the annular plastic heat shrinkable vapor absorber holding space 131 and the annular heat wax. A space 136 is formed. The thermal wax 138 is disposed to fill the annular thermal wax holding space 136, and the plastic heat shrinkable vapor absorber D is filled in the annular plastic heat shrinkable vapor absorber holding space 131.

The food container 20 having the inner sleeve member 102, the sealing destruction structure 122, the cover sleeve member seal 121 and the dry gas seal 123 is on the support cylinder 132 inside the cover sleeve member 30. It is inserted so that it can sit on.

The cylindrical rod CR has a through hole TH passing through its length and a three-way fitting TFW attached to the through hole TH. The first input portion of the three-way fitting TFW is connected by the drying gas hose DGH and is in fluid communication with the drying gas pressure canister DGC through the drying gas valve DGV. The second input portion of the three-way fitting TFW is connected to the vacuum pump VP through the vacuum valve Vv by the vacuum pump hose VPH. The third input of the three-way fitting TFW is a humidification liquid valve HLV connected to the humidification liquid valve HLT by a humidification liquid hose HLH.

The outer diameter of the cylindrical rod (CR) is manufactured to fit exactly inside the cover sleeve member 30, and about 20 mm is inserted into the open end of the cover sleeve member 30, and the cover sleeve member 30 is to seal its periphery. Heat shrinks. The humidification liquid valve (HLV), dry gas valve (DGV) and vacuum valve (Vv) are shut off.

Dry gas valve (DGV) and vacuum valve (Vv) are first opened at a low pressure of about 1 psig to purify any wet air and gas in cover sleeve member 30 using a vacuum pump (VP). GS) overflows the inside of the cover sleeve member 30. After a few seconds of purge, the dry gas valve DGV is turned off so that the vacuum pump VP slightly leans the dry gas DG remaining in the cover sleeve member 30 to a pressure just below the ambient atmospheric pressure. A shut-off valve to control the pressure may be provided, but the vacuum pump VP itself may be made to provide the necessary leanness.

Hot air (HA) from a heat source (HG), such as a heat gun, is first directed to the position of the cover sleeve member sealing portion 108 to shrink around the surface of the drying gas seal 123 to shrink the side wall of the food container ( 100), after which hot air (HA) is removed. This seals the dry gas GS with a dilute pressure in the dry gas chamber DGS under the dry gas seal 123.

Then, the drying gas valve (DGV) and the vacuum valve (Vv) are shut off, and the humidifying liquid valve (HLV) is opened so that the humidifying liquid (HL) is dried between the food container side wall 100 and the cover sleeve member side wall 101. The annular space above the gas seal 123 is filled to a level just below the cover sleeve member seal 121, and then the humidifying liquid valve is shut off.

The hot air (HA) from the heat source (HG) is now directed to the position of the cover sleeve member seal (108) to cause the cover seal (121) to contract and clamp against the food container sidewall (100), after which the hot air (HA) is removed. This seals the humidification liquid HL, and forms a humidification liquid chamber W between the dry gas seal 123, the cover seal 121, the food container side wall 100 and the cover sleeve member side wall 101.

Next, the additional material of the cover sleeve member 30 over the food container top wall seam 114 still attached to the cylindrical rod CR is cut to create the cover sleeve member side wall end 110. The extension grip 111 is snapped to the food container top wall seam 114 to act as an extension of the food container 20. The device 10 is now ready for use.

Method of operating the device according to the first embodiment

It is expected that the cooling operating means θ is activated before the food discharging means 113 is used. However, if the food discharging means 113 is operated before the cooling operation means θ, the food container side wall 100 is relaxed due to the pressure drop of the food container 20 and the dry gas seal against the food container side wall 100 It is expected that 123 will loosen, and therefore, the device 10 simply applies finger pressure 40 and presses the cover sleeve member sidewall 101 in the area of the dry gas seal 123 to prevent the dry gas seal 123. And by deforming the food container sidewall 100 and causing the humidification liquid HL to leak into the drying gas chamberDGS, it can still be activated as shown in FIG. 10. In either case, the humidifying liquid HL will pass between the dry gas seal 123 and the food container side wall 100 due to the gravitational pressure difference, thus activating cooling. Thus, when the food discharging means 113 is first used, a second cooling operating means is provided. When the cooling operation means θ is activated, the rotation relative to the food container side wall 100 of the cover sleeve member 30 together with the cover sleeve member seal 121 and the dry gas seal 123 is the sealing destruction structure 122 Crosses under the dry gas seal 123 and breaks the seal with the food container side wall 100 that holds the humidification liquid HL in the humidification liquid chamber W. The humidifying liquid (HL) enters between the outward protrusions and dissolves the ionizable compound (S) therein. This causes the first endothermic cooling of the humidifying liquid HL. The humidifying liquid HL also saturates the inner sleeve member side wall 105, and the wick portion 140 absorbs the humidifying liquid. The drying gas DG absorbs the humidified liquid vapor Vw from the wick 140, and its evaporation causes a second additional cooling of the humidified liquid HL. Further, the third cooling is achieved when the solution formed by the species of the soluble compound (DCC) in the compound (S) and the humidifying liquid are dried by evaporation of the humidifying liquid (HL) to the drying gas (GS).

The heat of evaporation (H) is removed as the drying gas (DG) becomes wet and its dew point temperature is lowered. Note that the drying gas (DG) temperature is not increased by this process because the dew point temperature removes the evaporation heat (h) of the humidifying liquid (HL). The higher dew point temperature of the drying gas DG saturates the drying gas chamber DGS and enters the restricted vapor passage 129a. Dry gas (DG) is an electromotive means of transport. The removal of polar water molecules in vapor form into the drying gas (DG) is due to the electromotive heat transfer potential. Dry gas (DG) alters the reactivity of the confined vapor passage 129a (respir. Physiol. 1997 jul; 109 (1):65-72). The negative ions of the drying gas DG attract the polar molecules of the humidification liquid HL in the limited vapor passage 129a. This is why the tendency to electrostatic effects increases when the air is dry.

The plastic heat shrinkable vapor absorber (D) may be one of a liquid, a gel, and a solid absorbing humidification liquid (HL) vapor (Vw). The humidifying liquid (HL) may also be a pressurized liquid in equilibrium with vapors such as ammonium solution, dimethyl ether solution and carbonate solution. In this case, Table 1 provides various combinations of plastic heat-shrink vapor absorbers (D), dry gases (GS) and humidification liquids (HL) that can be used with the present invention.

As the drying gas GS moistened by the humidified liquid vapor Vw passes through the limited vapor passage 129a and then the support cylinder hole 137, is absorbed by the plastic heat-shrink vapor absorber D and dehumidified, the vapor pressure is reduced. The dew point temperature of the lowered and dehumidified drying gas GS falls well below the dew point temperature of the humidified drying gas DG in the drying gas chamber DGS. The dehumidified drying gas (DG) in the drying gas chamber (DGS) is sucked again by the higher vapor pressure of the drying gas chamber (DGS) to absorb more vapor again and transport it to the plastic heat-shrink vapor absorber (D). The plastic heat-shrinkable vapor absorber D is heated while absorbing the humidified liquid vapor Vw, and the pre-stretched and tensioned annular plastic heat-shrinkable vapor absorber holding space wall 133 reacts to temperature rise by deformation and reduction in area. . When heated, the annular plastic heat-shrink vapor absorber holding space wall 133 contracts the surface area and moves outward from the food container domed bottom 22, causing the volume of the drying gas chamber (DGS) to increase, and thus the drying gas It creates a substantially low vapor pressure in a fixed amount of dilute dry gas DG in chamber DGS. This further lowers the vapor pressure of the drying gas DG in the drying gas chamber DGS, and the humidified liquid vapor Vw in the drying gas chamber DGS is pulled into the drying gas DG and evaporated. This deformation of the annular plastic heat shrink vapor absorber holding space wall 133 continues with the continuous generation of more evaporation heat h, so that the annular plastic heat shrink vapor absorber holding space wall 133 is preferably flat and thus Allows the volume of the drying gas chamber (DGS) to increase relative to the original volume.

In order to prevent the cover sleeve member lower wall 130 from collapsing or deformation, the support cylinder 132 absorbs the compressive force of the annular plastic heat-shrink vapor absorber holding space wall 133 against the food container bottom edge 21 And prevents the lower wall 130 of the cover sleeve member from being deformed. Therefore, the planarization of the annular plastic heat-shrink vapor absorber holding space wall 133 will not affect the structure of the cover sleeve member lower wall 130. Deformation and planarization of the annular plastic heat shrink vapor absorber holding space wall 133 increases the volume of the drying gas chamber (DGS), and because there is a fixed amount of drying gas (DG) in the drying gas chamber (DGS), drying A lower pressure is created inside the gas chamber DGS. The annular plastic heat-shrink vapor absorber holding space 131 is also made larger by the planarization of the annular plastic heat-shrink vapor absorber holding space wall 133. This causes the plastic heat-shrinkable vapor absorber D to continuously move, move, fall and diffuse over the flat annular plastic heat-shrinkable vapor absorber holding space wall 133. This diffusion agitates the plastic heat shrink vapor absorber (D) and makes it more effective because it has a larger surface area. Further, preferably the drying gas DG is at atmospheric pressure when stored between the drying gas chambers DGS. The negative pressure generated in the drying gas DG causes absorption of the humidified liquid vapor Vw into the drying gas DG by evaporation of the humidifying liquid HL. Due to the gasification of the humidifying liquid (HL), about 1840 times the expansion of the humidifying liquid (HL) into the humidifying liquid vapor (Vw) within the drying gas chamber (DGS) is the drying gas in relation to the annular plastic heat shrink vapor absorber holding space (131). Increase the relative vapor pressure in the chamber DGS. Thus, advantageously, the humidified liquid vapor Vw in the drying gas chamber DGS naturally wants to enter the plastic heat-shrink vapor absorber D. Thus, the drying gas DG is a means of electromotive heat transfer of the humidified liquid vapor Vw into the plastic heat-shrink vapor absorber D, which does not require a true vacuum.

As the drying gas (DG) transfers the humidified liquid vapor (Vw) to the plastic heat-shrink vapor absorber (D), the actual temperature rises due to heat generated by the plastic heat-shrink vapor absorber (D). The heat from the plastic heat-shrink vapor absorber D is partially absorbed by the drying gas DG, and its dew point temperature is further lowered. Due to this, the drying gas DG is transferred back to the plastic heat-shrink vapor absorber D, and more humidified liquid vapor Vw is collected from the drying gas chamber DGS. Cooling in this way continues to dehydrate the ionizable compounds on the dry gas chamber (DGS). The ionizable compound is not absolutely necessary for the present invention to work, but improves the cooling efficiency since the drying gas (DG) will even absorb the humidification liquid vapor (Vw) from the cold humidification liquid (HL). The ultimate evaporation heat source (h) is the food (P) that is cooled by this method. "Salting" the dry gas chamber (DGS) by drying the compound (S) back to its original form (if used) so that they can be reused for further cooling. Drying the drying gas (DG) by means of the plastic heat shrink vapor absorber (D) allows it to be reused for further cooling.

In addition, the deformation motion of the annular plastic heat-shrink vapor absorber holding space wall 133 causes the plastic heat-shrink vapor absorber (D) to move and diffuse, so that the unexposed plastic heat-shrink vapor absorber (D) is activated and the humidification liquid vapor (Vw) To induce absorption into the plastic heat shrinkable vapor absorber (D). Heat-absorbing heat wax 138, such as ordinary candle wax, absorbs the evaporation heat (h) from the plastic heat-shrink vapor absorber (D) and stores the evaporation heat (h), the support cylinder 132 and the cover sleeve member side wall ( It is envisaged that it may be disposed in the annular heat wax holding space 136 between 101). However, this has been found to be effective only when a large amount of plastic heat-shrink vapor absorbent (D) is used in a large food container (20) having a volume exceeding 20 oz.

In addition, the cover sleeve member 30 may be made of a shrinkable material such as TPXTM formed by a combination of a plastic material called polymethylpentene and glass beads, and the resulting cover sleeve member 30 is formed through its structure. The absorbed evaporation heat (h) can be quickly released and the evaporation heat (h) can be quickly released into the atmosphere. In addition, the deformation motion of the annular plastic heat-shrinkable vapor absorber holding space wall 133 is, when the heated air volume under the flat annular plastic heat-shrinkable vapor absorber holding space wall 133 is discharged, the atmospheric air therein is converted to plastic heat-shrinkable vapor. It absorbs heat from the absorber D and, if used, removes this heat from the atmosphere through the cardboard hole 137 or directly.

A cardboard 134 is provided but is not required. Preferably, but not necessarily, the cardboard 134 is made to fit and cover the cover sleeve member lower wall 130 and adhered to the cover sleeve member lower wall 130 to protect the consumer from possible burns. The cardboard 134 has a small central cardboard hole 135 that allows a free flow of gas into the atmosphere due to the planarization of the annular plastic heat shrink vapor absorber holding space wall 133.

In all embodiments, it is contemplated that the walls and materials used to form the inner sleeve member 102 may be laminated with an ionizable compound (S) having a reversible endothermic reaction with the humidifying liquid (HL).

The drying gas DG is preferably provided inside the drying gas chamber DGS just below ambient atmospheric pressure. The drying gas GS is provided by the drying gas source DGS, and fills the drying gas chamber DGS, and the empty space between the plastic heat-shrink vapor absorber D and the inner sleeve member 102.

And allows a variety of distinct reactive compounds (RCCs) to be stored between the independent protrusions. The number of protrusions should be at least one or more so that the reactive compound (RCC) can be used with the device 10. Various protruding shapes of the inner sleeve member sidewall 105, such as the protrusions described above, can be used to increase the strength and surface area of the inner sleeve member 102. The protruding shape is divided into protrusions such as the inwardly protruding portions 103 and the outwardly protruding portions 104 shown as examples of FIGS. 11, 12, 13 and 20 to give strength to the inner sleeve member 102 and also The reacting compound (RCC) is placed inside it and the drying gas (DG) fills it and causes it to saturate. Preferably, the protruding protrusion of the inner sleeve member 102 forms a partition on the inner sleeve member side wall 105 so that the drying gas DG can interact with the reacting compound (RCC). The inwardly protruding portion 103 of the inner sleeve member side wall 105 includes the food container side wall 100 and the food container side wall 100 to form a compartment for the reactive compound (RCC) between the inner sleeve member side wall 105 and the food container side wall 100. It must be in tangential contact frictionally.

The inner sleeve member side wall 105 is attached in a circumferential direction to frictionally tangentially contact the food container side wall 100 so as to at least partially cover the food container side wall 100 under the cover sleeve member seal 121. Grease, soft and pliable adhesives and waxes can also be used to securely hold the inner sleeve member sidewalls in place and at least form a separate compartment from the food container sidewalls 100. Preferably, the inner sleeve member sidewall 105 extends under the cover sleeve member seal 121 to partially cover as much as possible of the exposed surface of the food container sidewall 100.

As before, the dry gas seal 123 is preferably provided in the form of an O-ring seal, a metal band seal, a rubber band seal, a putty seal and a sealing wax seal, an adhesive binder, and a thin loop, generally of a ring structure. Is formed in a shape. The dry gas seal 123 is hermetically sealed in a circumferential direction around the inner sleeve member side wall 105 in a plane parallel to the diameter plane of the food container 20 and close to the inner sleeve member side wall lower edge 24 do. The maximum distal separation between the cover sleeve member seal 121 and the dry gas seal 123 is optimal for this embodiment of the invention to work. When disposed around the inner sleeve member sidewall lower edge 24, the drying gas seal 123 should have an outer diameter slightly larger than the outer diameter of the outward protrusion 104 of the inner sleeve member 102. This allows a suitable seal to be formed by the dry gas seal 123 with the cover sleeve member 30.

As before, the inner sleeve member side wall 105 may also cover and surround the entire food container side wall 100 under the dry gas seal 123, and the inner sleeve member lower wall 106 is a cup-shaped sleeve structure. It is anticipated that it extends to cover and surround the vessel domed lower wall 22.

As before, the inwardly protruding portion 103 of the inner sleeve member 102 is preferably kept hermetically tangential to the food container side wall 100 by friction. And again, the outward protrusion 104 and the food container side wall 100 form an assembly of separate compartments from the food container side wall 100. The inwardly protruding portion 103 and the cover sleeve member sidewall 101 also form an assembly of separate compartments above the drying gas seal 123. The compartment formed by the outward protrusion 104 and the food container side wall 100 is a reactive compound selected from pairs of hydration compounds (S) that endothermicly react to produce a humidifying liquid (HL) to be used by the device 10. Filled with (RCC). Each of the selected pair of reactive compounds (RCC) is disposed in a neighboring compartment formed by the outward protrusion 104 and the food container side wall 100.

A cover sleeve member 30 is provided. The cover sleeve member 30 is made of one of other materials such as stretch-molded polyethylene terephthalate (PET), polyvinyl chloride (terephthalate or PVC), and deep-drawn aluminum, and is formed of a thin-walled cup-shaped sleeve. ) Surrounds all or part of. Preferably, the cover sleeve member 30 has a cover sleeve member side wall 101 that can be slidably fitted over the inner sleeve member side wall 105 and has a shape that follows the contour of the food container side wall 100. The cover sleeve member side wall 101 may take various shapes, but when formed as described above, the cover sleeve member side wall 101 is sealedly coupled with a part of the food container side wall 100 to form a dry gas seal ( 123) and the cover sleeve member seal 121 should be allowed to form and hold.

The cover sleeve member sidewall 101 covers all or part of the sealed food container 20 containing the food P to which the inner sleeve member 102 is attached. The cover sleeve member side wall 101 may preferably extend to partially cover the food container side wall 100 and partially cover the food container upper wall 107. The cover sleeve member sidewall 101 can be made of many types of materials, but heat-shrinkable plastics such as PET and PVC are preferred. The cover sleeve member sidewall 101 may also be made of aluminum as a deep drawn container and must be reformable by spin molding and crimping to form a seal with the food container 20.

As before, the cover sleeve member 30 has a cover sleeve member lower wall 130 sealingly connected to the cover sleeve member side wall 101. The cover sleeve member lower wall 130 is hermetically connected to the cover sleeve member shrinkable annular wall 133 protruding inward. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding.

As mentioned earlier, it is contemplated that the cover sleeve member 101 may be made of spun or deep drawn aluminum, and may be formed to provide all of the required sealing by partially spin forming and rolling it. In this case, the cover sleeve member shrinkable annular wall 133 may be made of a heat shrinkable PET or PVC material and may be added to the cover sleeve member lower wall 130 by ultrasonic welding or bonding. If necessary, a thin-walled open end support cylinder 132 with a support cylinder hole 137 close to the upper end may be used as the cover sleeve member lower wall between the cover sleeve member sidewall 101 and the cover sleeve member shrinkable annular wall 133. It is placed on the opposite open end of the top 130 and is arranged to contact the food container 20. If the cover sleeve member side wall 101 is made sufficiently strong, the support cylinder 132 is not required.

In addition, as described above, the annular plastic heat-shrinkable vapor absorber holding space 131 in the cover sleeve member 30 includes an inner surface of the support cylinder 132 and an inner surface of the cover sleeve member shrinkable annular wall 133 and a lower portion of the cover sleeve member. It is formed between the spaces defined by the inner surface of the wall 130. The annular plastic heat shrinkable vapor absorber holding space 131 is filled with the plastic heat shrinkable vapor absorber D up to the height of the cover sleeve member shrinkable annular wall 133.

The annular heat wax holding space 136 is also formed in the cover sleeve member 30 between the outer surface of the support cylinder 132 and the inner surface of the cover sleeve member side wall 102 and the inner surface of the cover sleeve member lower wall 130. do. The annular thermal wax holding space 136 may be optionally filled up to the height of the support cylinder 132 with suitable thermal wax 138 that can be melted at a temperature in the range of 70° F. to 160° F. The support cylinder 132 prevents the cover sleeve member lower wall 130 from collapsing and deforming its shape relative to the food container 20.

When the cover sleeve member rests on the food container 20 and the attached inner sleeve member 102, the inner sleeve member lower wall 106 rests on the support cylinder 137 and the outward protrusion on the inner sleeve member side wall 105 ( 104) contacts the side wall 101 of the cover sleeve member in a tangential direction to form a partition between the walls. The cover sleeve member side wall 101 covers the attached inner sleeve member 102 and covers the food container side wall 100 wholly or partially. The inwardly protruding portion 103 and the cover sleeve member side wall 101 form an assembly of separate compartments above the dry gas seal 123 as shown in FIGS. 13 and 20. The cover sleeve member side wall 101 may preferably extend to partially cover the food container side wall 100 and partially cover the food container upper wall 107.

As before, the cover sleeve member side wall 101 must be accurately fitted on the inner sleeve member 102 and contact the drying gas seal 123 in the exact tangential direction. As before, the cover sleeve member sidewall 101 has a cover sleeve member sealing portion 118 that is reduced in diameter to form a seal between the inner sleeve member sidewall 105 and the cover sleeve member sidewall 101. This seal seals the dry gas (GS) dilution just below atmospheric pressure, and thus the support cylinder 132, the annular heat wax holding space 136 with the heat wax 138 inside, and the plastic heat shrink vapor absorber (D ) Is used to form a dry gas chamber (DGS) under the dry gas seal 123 accommodating the annular plastic heat-shrink vapor absorber holding space 131 contained therein.

Preferably, more reactive compound (RCC) is disposed in the compartment thus formed by the inwardly protruding portion 103 and the cover sleeve member side wall 101. These compartments are adjacent to the reactive compound (RCC) disposed in the compartment previously formed by the outward protrusion 104 and the food container side wall 100. Of course, the inward protrusions 103 and the outward protrusions 104 may be used to store individual and different species of reactive compounds (RCCs) selected in pairs, respectively. Thus, one or more pairs of reactive compounds (RCCs) can be used with the device 10. Preferably, various distinct reaction compounds (RCC) capable of endothermic reaction with each other are BA(OH) ₂ 8H ₂ O(s) and NH ₄ SCN(s), NH ₄ NO ₃ (s) and NH ₄ CL It is a species selected from the same pair as (s). This reactive compound (RCC) has a humidified liquid (HL) stored between the hydrated structures.

Accordingly, the humidification liquid chamber w is formed on the dry gas seal 123 having the outwardly protruding portions 104 and the inwardly protruding portions 103 containing the reaction compound (RCC) having water as the humidifying liquid HL. In order to avoid premature reaction, pairs of reactive compounds (RCC) capable of reacting with each other are disposed on separate outward protrusions 104 separated by inwardly protrusions 103, respectively. The same is true for the reactive compounds disposed on separate inward protrusions 103 each separated by outward protrusions 104.

Dry gas (GS) dilution just below atmospheric pressure is provided to further fill and purge the cover sleeve member 30. The cover sleeve member side wall 101 has a cover sleeve member seal 108 that can be contracted in diameter to seal the cover seal 121 and form the cover sleeve member side wall seal 109. When the diameter is reduced, the cover sleeve member seal 108 forms a seal with the cover seal 121 between the food container upper wall seam 114 and the cover sleeve member 30 to form a humidification liquid chamber (W) from the atmosphere. ) Is sealed.

As before, it is expected that the cover sleeve member sidewall end 110 will be located in the cover sleeve member seal 108, but the cover sleeve member sidewall end 110 may extend beyond the cover sleeve member seal 108. Is considered.

The cover sleeve member seal 108 may be heated and heat-shrunk when made of a heat-shrinkable material, or roll a roll formed by a rolling molding machine to shrink the diameter and attach the cover seal 121 to the food container upper wall seam 114. It can be sealed and retain lean dry gas (GS) therein.

13 shows the separation arrangement of the reactive compound (RCC) in the humidified liquid chamber (W).

Manufacturing method of the second embodiment

A standard food container 20 is provided.

As before, the dry gas seal 123 is provided, and first, in a plane parallel to the diameter plane of the food container 20, it is disposed in a circumferential direction around the food container side wall 100 in a circumferential direction, so that the inner sleeve member side wall lower edge (24) Bend the circumference and seal it.

As described above, the inner sleeve member 102 is preferably provided as a cylindrical structure having an inwardly protruding portion 103 and an outwardly protruding portion 104. The inwardly protruding portion 103 must have a diameter that is slide-fitted onto the food container side wall 100. Accordingly, the inner sleeve member 102 is circumferentially circumferentially slid over the food container side wall 100 to be seated on the drying gas seal 123 and at least partially cover the food container side wall 100 above the dry gas seal 123. Attached with

Then, the desired species of the reactive compound (RCC) is charged into each outward protrusion 104 forming each chamber.

As before, the cover sleeve member seal 121 is provided, and the food container upper wall seam 114 is airtightly disposed around the food container side wall 100 in a plane parallel to the diameter plane of the food container 20 ) Is bent around.

As before, a cover sleeve member 30 is provided. The cover sleeve member side wall 101 should be longer than the food container 20 and, in practice, preferably extends at least 50 mm beyond the food container top wall 107 for manufacturing purposes.

In order to avoid excess, as before, the support cylinder 132 (an example that is not absolutely necessary, not shown) is to form an annular plastic heat shrink vapor absorber holding space 131 and an annular heat wax holding space 136 It may rest on the lower wall 130 of the cover sleeve member having a support cylinder hole 137 close to the food container 20. A thermal wax 138 (not shown, as an example not absolutely necessary) is disposed to fill the annular thermal wax holding space 136. The plastic heat shrinkable vapor absorber D is filled in the annular plastic heat shrinkable vapor absorber holding space 131.

The sub-assembly of the food container 20, the inner sleeve member 102, the cover sleeve member seal 121 and the drying gas seal 123 has the inner sleeve member lower wall 106 spaced apart on the plastic heat-shrink vapor absorber (D). In a state, the cover sleeve member is frictionally seated against the side wall 101. Next, the desired species of reactive compound (RCC) is filled with the cover sleeve member sidewall 101 into each inwardly protruding portion 103 forming each chamber.

The cylindrical rod CR is provided as before. The humidification liquid valve (HLV), dry gas valve (DGV) and vacuum valve (Vv) are shut off.

Dry gas valve (DGV) and vacuum valve (Vv) are first opened at a low pressure of about 1 psig to purify any wet air and gas in cover sleeve member 30 using a vacuum pump (VP). GS) overflows the inside of the cover sleeve member 30. After a few seconds of purge, the dry gas valve DGV is turned off so that the vacuum pump VP slightly leans the dry gas DG remaining in the cover sleeve member 30 to a pressure just below the ambient atmospheric pressure. Hot air (HA) from the heat source (HG) is first directed to the position of the cover sleeve member side wall 118 with the cover sleeve member seal 119 between the cover sleeve member side wall 100 with respect to the dry seal 123. The diameter is heat-shrinkable to form a seal in, and the dry gas seal 123 is sealed against the inner sleeve member side wall 105, after which the hot air HA is removed. This traps the dry gas GS in a lean state in the plastic heat-shrink vapor absorber D under the dry gas seal 123.

As before, when made of heat-shrinkable plastic, hot air (HA) is directed to the position of the cover sleeve member sealing portion 108 of the cover sleeve member side wall 101 to be around the surface of the cover sleeve member seal 121 The cover sleeve member seal 108 is contracted and clamped to clamp it against the food container upper wall seam 114 and form a seal, after which the hot air HA is removed. This seals the humidified liquid chamber W with the lean dry gas GS.

When made of deep-drawn spun aluminum, the forming rollers of the rolling forming machine (RFM) are directed to the position of the cover sleeve member seal 108 of the cover sleeve member side wall 101 so as to surround the surface of the cover sleeve member seal 121 The cover sleeve member seal 108 is contracted and clamped to clamp it against the food container upper wall seam 114 to form a seal.

Thus, the lean pressure dry gas GS is now sealed inside the humidification liquid chamber w and inside the drying gas chamber DGS and also penetrates the plastic heat-shrink vapor absorber D. Then, the dry gas valve DGV and the vacuum valve Vv are shut off. As before, the additional material of the cover sleeve member 30 still attached to the cylindrical rod CR is cut to create the cover sleeve member sidewall end 110. The device 10 is now ready for use.

How the device works

The cooling actuating means 40 is activated by using the finger pressure f to deform the dry gas seal 123 causing fluid communication between the humidified liquid chamber W and the dry gas chamber DGS. It is expected that the cooling operating means 40 is activated before the food discharging means 113 is used. However, if the food discharging means 113 is operated before the cooling operation means, the food container side wall 100 is relaxed due to the pressure drop of the food container 20 and the dry gas seal 123 against the inner sleeve member side wall 105 ) Becomes loose, and thus, it is expected to cause fluid communication between the humidified liquid chamber W and the drying gas chamber DGS and the plastic heat-shrink vapor absorber D.

The cover sleeve member side wall 101 is hand massaged against the inner sleeve member side wall 105 so that the reaction compounds (RCC) in the humidifying liquid chamber W react with each other to endothermic cooling and simultaneously generate the humidifying liquid HL. can do. The massage provides a first cooling means of the device 10 by endothermic reaction cooling by deforming the inward protrusion and the outward protrusion 104 of the inner sleeve member 102 so that the reaction compounds (RCC) are mixed and reacted with each other. A means for generating a humidifying liquid HL for the second cooling means is provided.

The dilution of the drying gas GS will cause the humidification liquid HL thus produced by the reaction to evaporate into the drying gas dg as humidification liquid vapor Vw. The drying gas DG absorbs the humidified liquid vapor Vw, which lowers the dew point temperature of the drying gas DG and becomes a wet gas in the third cooling means of the apparatus 10. The additional heat of evaporation (h) is removed from the humidification liquid (HL) by the drying gas (DG) as the drying gas becomes wet and the dew point temperature is lowered. The drying gas DG having a higher dew point temperature saturates the drying gas chamber DGS and is absorbed by the plastic heat shrink vapor absorber D in the annular plastic heat shrink vapor absorber holding space 131. The plastic heat-shrinkable vapor absorber D is heated while absorbing the humidified liquid vapor Vw, and the annular plastic heat-shrinkable vapor absorber holding space wall 133 stretched by stretch molding reacts to temperature rise by deformation and reduction in area.

As before, when heated, the annular plastic heat-shrink vapor absorber holding space wall 133 shrinks the surface area and moves outward away from the food container domed bottom 22, and thus the drying gas chamber (DGS) and the humidified liquid chamber. It causes the volume of (W) to increase, thus creating a substantially low vapor pressure in a fixed amount of lean dry gas (DG) within the drying gas chamber (DGS). This lowers the vapor pressure of the drying gas DG in the drying gas chamber DGS. The pressure in the drying gas chamber (DGS) is now lower and absorbs more humidified liquid vapor (Vw) to continue the cooling process.

In addition, the deformation motion of the annular plastic heat-shrink vapor absorber holding space wall 133 causes the plastic heat-shrink vapor absorber (D) to move and diffuse, so that the unexposed plastic heat-shrink vapor absorber (D) is activated and the humidification liquid vapor (Vw) To cause absorption into the plastic heat-shrinkable vapor absorber D, and the second cooling means is provided by evaporation of the humidification liquid HL generated by the reaction.

Third embodiment of the present invention

15, a standard food container 20 is provided. This embodiment is only a different version of the first embodiment and the second embodiment having the same components. The difference between the third embodiment and the first embodiment is that the dry gas seal 123 is made at the inner sleeve member sidewall upper edge 105a and the food container sidewall 100 of the inner sleeve member sidewall 105.

As before, the cover sleeve member seal 121 is made of one of an O-ring seal, a metal ring seal, a rubber band seal, a putty seal, a sealing wax seal, and an adhesive binder as described in the first embodiment of the present invention. It is provided in the form of a thin loop structure. The cover sleeve member seal 121 must be expandable to form an airtight sealing band around the food container 20. The loop diameter of the cover sleeve member seal 121 is circumferentially and hermetically arranged around the food container upper wall seam 114 in a plane parallel to the diameter plane of the food container 20.

As before, the dry gas seal 123 is preferably an O-ring seal, a metal band seal, a rubber band seal, a putty seal and a sealing wax seal, an adhesive binder, as described in the first embodiment of the present invention. It is provided in the form of a thin loop, usually formed in the form of a ring structure. The dry gas seal 123 is sealed in a circumferential direction around the side wall 100 of the food container in a plane parallel to the diameter plane of the food container 20 and spaced approximately 20 mm from the cover sleeve member seal 121. Is placed.

As before, the thin cup-shaped inner sleeve member 102 has an inner sleeve member side wall 105 and an inner sleeve member lower wall 106. The inner sleeve member 102 is a thin film having an inner sleeve member lower wall 106 and an inner sleeve member side wall 105 partially surrounding the food container side wall 100 and forming an annular gap with the food container side wall 100. It is a cup-shaped structure on the wall.

As before, the inner sleeve member 102 is preferably formed from an injection molded plastic material such as PET and PVC. The inner sleeve member 102 may also be formed from a thin deep drawn aluminum cup. The inner sleeve member 102 may also be injection molded, but it is contemplated that the inner sleeve member 102 may be formed of a heat shrinkable material such as PET and PVC. In this way, the inner sleeve member 102 surrounds the food container bottom domed wall 22, and the inner sleeve member side wall 105 together with the inner sleeve member upper edge 105a directly above the dry gas seal 123 It should be tall enough to cover most of the sidewall 100 of the container. The inner sleeve member side wall 105 is clamped in diameter over the dry gas seal 123 to form a fluid seal between the food container side wall 100. The inner surface of the inner sleeve member side wall 105, the drying gas seal 123, the outer surface of the food container side wall 100, the outer surface of the food domed lower wall 22 and the inner surface of the inner sleeve member lower wall 106 Forms a humidifying liquid chamber W filled with humidifying liquid HL to partially enclose the food container side wall 100 and surround the food domed lower wall 22. The humidifying liquid fills the humidifying liquid chamber W right below the dry gas seal 123. Thus, when the inner sleeve member 102 is heat-shrunk or crimped to seal over the dry gas seal 123, the dry gas seal 123 is partially between the inner sleeve member side wall 105 and the food container side wall 100. A seal is formed to form a sealed humidification liquid chamber W containing the humidification liquid HL. Accordingly, the humidifying liquid HL partially surrounds the food container lower domed wall 22 and the food container side wall 100.

As before, the core portion 140 is optionally provided and is not required. The wick portion 140 is coupled to the outer wall of the inner sleeve member side wall 105 as described above.

As before, the cover sleeve member sidewall 101 is a cover sleeve member sealing portion that can be reduced in diameter to form a limited vapor passage 119a on the wick portion 140 with respect to the inner sleeve member sidewall 105 Has 118. Compression of the cover sleeve member seal 118 also causes the dry gas seal 123 to seal between the inner sleeve member side wall 105 and the food container side wall 100.

As before, the cover sleeve member seal 108 forms the cover sleeve member seal 109 together with the cover seal 121 when the diameter is reduced, and the food container upper wall to form a dry gas chamber (DGS). The circumference of the seam 114 is clamped. The drying gas chamber (DGS) includes a cover sleeve member seal (121), a cover sleeve member side wall (101), a food container side wall (100) partially above the drying gas seal (123), and a drying gas seal (123). , Extending between the outwardly facing surfaces of the inner sleeve member 102. Drying gas DG, preferably just below the ambient atmospheric pressure, is provided inside the drying gas chamber DGS.

As before, the cover sleeve member 30 has a cover sleeve member lower wall 130 sealingly connected to the cover sleeve member side wall 101. The cover sleeve member lower wall 130 is hermetically connected to the cover sleeve member shrinkable annular wall 133 protruding inward. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding.

The food container 20 is preferably a cylindrical beverage food container of standard design and has a standard food discharging means 113 and a standard food discharging port 112.

A cover sleeve member 30 is provided. As described above, the cover sleeve member 30 is preferably made of one of stretch molding, stretch blown PET and PVC to form a heat shrinkable cover sleeve member 30 in the form of a thin-walled cup-shaped sleeve, but also deeply drawn. It can be formed of thin-walled aluminum. The cover sleeve member 30 has a cover sleeve member side wall 101 surrounding all or part of the food container 20 with the inner sleeve member 102 attached to the food container side wall 100. The cover sleeve member sidewall 101 can take a variety of shapes to provide rigidity, but should allow the cover sleeve member sidewall 101 to mate with a portion of the food container sidewall 100 as described above. The cover sleeve member side wall 101 entirely or partially covers the sealed food container 20 containing the food P. The cover sleeve member sidewall 101 may be made of another plastic material that can shrink when heat is applied to the surface. The cover sleeve member side wall 101 may preferably extend to partially cover the food container side wall 100 and partially cover the food container upper wall 107. The cover sleeve member sidewall 101 is fitted in a sliding manner only to the wick portion 140 on the inner sleeve member 102 and surrounds it in the circumferential direction. The cover sleeve member side wall 101 may preferably extend to partially cover the food container side wall 100 and partially cover the food container upper wall 107. It is expected that the cover sleeve member side wall end 110 will be located in the cover sleeve member seal 108, but the cover sleeve member side wall end 110 is beyond the cover sleeve member seal 108 and the food container top wall 107 It is considered that it can extend over ). When the cover sleeve member seal 108 is retracted, it is clamped around the surface of the inner sleeve member 102, and the surface of the dry gas seal 123, the surface of the cover sleeve member seal 121, and partially the food container It forms an annular dry gas chamber (DGS) defined by the sidewall 100 and the surface of the cover sleeve member sidewall in part.

The cover sleeve member 30 protects the inner sleeve member 102. When the cover sleeve member side wall 101 is heat-shrinkable, it should not be clamped around the surface of the inner sleeve member 102, but the humidification liquid vapor (Vw) is the cover sleeve member side wall 101 and the outward inner sleeve member side wall 105 You should allow it to go through. The cover sleeve member seal 118 is partially deformed around the inner sleeve member 102 to hold it firmly and provide a limited vapor passage 119a.

The outward facing surface of the inner sleeve member sidewall 105, the drying gas seal 123, and the partially inward facing surface of the cover sleeve member 30 form a drying gas chamber DGS. The outward facing surface of the food container side wall 100, the cover sleeve member seal 121 and the partial inward surface of the food container side wall 101 form a humidifying liquid chamber w.

The cover sleeve member 30 has a cover sleeve member lower wall 130 sealingly connected to the cover sleeve member side wall 101. The cover sleeve member lower wall 130 is hermetically connected to the cover sleeve member shrinkable annular wall 133 protruding inward. The cover sleeve member retractable annular wall 133 is flexible and can react to pressure changes by collapsing or expanding. The cover sleeve member shrinkable annular wall 133 is filled with a plastic heat shrinkable vapor absorber D up to the level of the cover sleeve member shrinkable annular wall 133. The inner surface of the cover sleeve member 30 under the cover sleeve member seal 121 forms a drying gas chamber DGS containing the drying gas GS.

It is contemplated that the cover sleeve member 101 may be made of spun or deep drawn aluminum, and may be formed to provide all the sealing required by spin forming and rolling in part. In this case, the cover sleeve member shrinkable annular wall 133 may be made of a heat shrinkable PET or PVC material and may be added to the cover sleeve member lower wall 130 by ultrasonic welding or bonding. If necessary, a thin walled open end support cylinder 132 provided as before with a support cylinder hole 137 close to the upper end, the cover between the cover sleeve member sidewall 101 and the cover sleeve member shrinkable annular wall 133 It lies at an opposite open end on the sleeve member lower wall 130 and is arranged to contact the inner sleeve member lower wall 105. If the cover sleeve member side wall 101 is made sufficiently strong, the support cylinder 132 is not required.

The annular plastic heat-shrinkable vapor absorber holding space 131 in the drying gas chamber (DGS) includes an inner surface of the support cylinder 132 and an inner surface of the cover sleeve member shrinkable annular wall 133 and the inner surface of the cover sleeve member lower wall 130. It is formed between the spaces defined by the surface. The annular plastic heat-shrinkable vapor absorber holding space 131 is in fluid communication with the drying gas chamber DGS and is in the drying gas chamber DGS. The annular heat wax holding space 136 is formed in the drying gas chamber (DGS) between the outer surface of the support cylinder 132 and the inner surface of the cover sleeve member side wall 102 and the inner surface of the cover sleeve member lower wall 130 do. The annular thermal wax holding space 136 can optionally be filled with a suitable thermal wax 138 that can be melted at temperatures ranging from 70° F. to 160° F. The support cylinder 132 prevents the cover sleeve member lower wall 130 from collapsing and deforming its shape relative to the food container 20.

Cooling operation when the finger f is used to deform it by pressing the cover sleeve member side wall 101 at the location of the drying gas seal 123 and expose the humidifying liquid HL from the humidifying liquid chamber W into the drying gas chamber Means 40 are provided.

It is contemplated that the inner sleeve member 102 may have a shape and shape that may help increase the surface area to aid evaporation in the dry gas chamber (DGS). It is expected that the ionizable compound (S) is selected from the species of the dissolving compound (DCC) which dissolves endothermally, and can be disposed on the inwardly protruding portion 103 of the inner sleeve member 102 as described above. This can be done by implanting the ionizable dissolving compound (DCC) into the outer surface of the inner sleeve member 102 as described above. The restricted vapor passage 119a is formed by clamping the cover sleeve member sealing portion 118 onto the wick portion 140.

The cyclic plastic heat-shrinkable vapor absorber holding space 131 holds a plastic heat-shrinkable vapor absorber D such as silica gel, molecular sieve, clay desiccant such as montmorillonite clay, and calcium oxide and calcium sulfide. The annular plastic heat-shrinkable water vapor absorber holding space 131 is stretch-molded from a heat-shrinkable material including various types of heat-shrinkable PET and various types of heat-shrinkable PVC. The cover sleeve member shrinkable annular wall 133 responds to heat by deforming and contracting the surface area. Advantageously, the cover sleeve member shrinkable annular wall 133 tends to shrink in surface area and flatten with the heat received from the plastic heat shrink vapor absorber to increase the volume of the drying gas chamber (DGS). This deformation is caused by heating while the plastic heat-shrink vapor absorber D absorbs the humidification liquid HL vapor Vw from the humidified drying gas DG in the drying gas chamberDGS. Drying gas (GS) in the drying gas chamber (DGS) is in fluid communication with the plastic heat-shrink vapor absorber (D) and the limited vapor passage (119a), so advantageously the annular plastic heat-shrink vapor absorber holding space 131 is an inner sleeve member It is in fluid communication with the outer wall of 102.

The shape of the cover sleeve member shrinkable annular wall 133 should minimize the drying gas chamber (DGS) before it is heated, and therefore, intrusion into the drying gas chamber (DGS) will maximize and increase the volume of the drying gas chamber (DGS). Should be designed to In the example shown in Fig. 1, the shape of the cover sleeve member shrinkable annular wall 133 is an inverted cup. However, as can be seen in the various drawings, it can take many different shapes.

When heated, the cover sleeve member contractible annular wall 133 contracts and minimizes its area. The annular plastic heat-shrink vapor absorber holding space 131 expands and moves to the outside, and increases the volume of the drying gas chamber (DGS) so that a pressure substantially lower than the initial pressure, preferably just below the ambient atmospheric pressure, is applied to the drying gas (DG). ). This lowers the vapor pressure of the drying gas DG and any vapor in the drying gas chamber DGS, and thus the vapor pressure in the inner sleeve member 102. Accordingly, it is expected that the cover sleeve member side wall 100 may be designed as an annular protrusion or side protrusion to reinforce it and prevent it from collapsing by the lean force generated by the plastic heat-shrink vapor absorber D. For example, the inward protrusions 103 and outward protrusions 104 shown in FIG. 2 have all the strength and strength required to support the cover sleeve member sidewall 100 from the lean pressure generated by the plastic heat shrink vapor absorber D. It may be sufficient to provide surface area. It is expected that the humidification liquid chamber W can be made to maintain sufficient humidification liquid HL without overflow when receiving the humidification liquid.

As before, the outward surface of the inner sleeve member 102 forms part of the drying gas chamber (DGS). This surface is also heat-shrunk to form a shape by hot spraying with a stream of particles of ionizable compounds carried by heated air at high impact pressures as they heat shrink to form a shape on the mold. It can be layered with. Preferably, drying gas (DG) just below atmospheric pressure is provided inside the drying gas chamber (DGS) to fill the drying gas chamber (DGS) and between the drying gas chamber (DGS) (low pressure) and the humidified liquid chamber (W). Creates a slight pressure difference.

Fig. 16 shows a device 10 according to a fourth embodiment when the cooling means F are operated.

It is arranged airtightly in the circumferential direction, and is bent around the side wall 100 of the product container.

The inner sleeve member 102 is provided in the form of a cup sleeve as described above, and is provided to frictionally wrap and fit the food container side wall 100 and covers the dry gas seal 123. As before, the wick portion 140 is optionally provided and is coupled to the outer wall of the inner sleeve member side wall 105.

The humidification liquid HL is poured into the inner sleeve member 102 and fills the humidification liquid chamber W between the food container and the inner sleeve member 102 to just below the drying gas seal 123.

The hot air (HA) is first directed to the inner sleeve member 102 at the location of the dry gas seal 123, partially contracting and clamping the inner sleeve member 102 around the surface of the dry gas seal 123 , After that, hot air (HA) is removed. This seals the humidification liquid HL and forms a sealed humidification liquid chamber w formed by the annular gap between the food container and the inner sleeve member 102 up to just below the drying gas seal 123.

As before, the cover sleeve member 30 is provided as a cup-shaped structure having a straight cover sleeve member sidewall 101 as shown in FIG. 2.

As before, the cover sleeve member side wall 101 must be longer than the food container 20 and extend at least 50 mm beyond the food container top wall 107. The cover sleeve member sidewall 101 is fitted over the inner sleeve member 102.

As before, the thermal wax 138 is disposed to fill the annular thermal wax holding space 136 and holds the plastic heat shrinkable vapor absorber D filled in the annular plastic heat shrinkable vapor absorber holding space 131.

As before, the food container 20 together with the inner sleeve member 102, the attached inner sleeve member 102, the cover sleeve member seal 121 and the dry gas seal 123 is inside the cover sleeve member 30. It is inserted so as to be seated in the support cylinder 132.

As before, the cylindrical rod CR has a through hole TH passing through its length and a three-way fitting TFW attached to the through hole TH. As before, the first input portion of the three-way fitting TFW is connected by the drying gas hose DGH and is in fluid communication with the drying gas pressure canister DGC through the drying gas valve DGV. As before, the second input portion of the three-way fitting TFW is connected to the vacuum pump VP through the vacuum valve Vv by the vacuum pump hose VPH. As before, the third input of the three-way fitting TFW is connected by the humidification liquid tank HLT through the humidification liquid valve HLV.

As before, the outer diameter of the cylindrical rod (CR) is manufactured to fit exactly inside the cover sleeve member 30, and about 20 mm is inserted into the open end of the cover sleeve member 30, and the cover sleeve member 30 has a circumference thereof. Heat shrink to seal it. The humidification liquid valve (HLV), dry gas valve (DGV) and vacuum valve (Vv) are shut off.

As before, the drying gas valve (DGV) and vacuum valve (Vv), which are regulated to a low pressure of about 1 psig, are opened first, so that the inner sleeve member 102, in the drying gas chamber DGS, and the cover sleeve member 30 Dry gas (GS) overflows the inside of the cover sleeve member 30 so as to purge any wet air and gas in the inside of the vacuum pump (VP) using a vacuum pump (VP). After a few seconds of purge, the dry gas valve DGV is turned off so that the vacuum pump VP slightly leans the dry gas DG remaining in the cover sleeve member 30 to a pressure just below the ambient atmospheric pressure. A shut-off valve to control the pressure may be provided, but the vacuum pump VP itself may be made to provide the necessary leanness.

The hot air (HA) from the heat source (HS) is now directed onto the position of the food cover sleeve member seal 108 of the cover sleeve member side wall 101 and is contracted and clamped around the cover seal 121, after which the high temperature Air (HA) is removed. This seals and forms the drying gas GS in the drying gas chamber DGS.

Next, the additional material of the cover sleeve member 30 attached to the cylindrical rod CR is cut to create the cover sleeve member sidewall end 110. The device 10 is now ready for use.

How the device works

It is expected that the cooling operation means 40 is activated by the finger f pressure to deform the dry gas seal 123 before the food discharging means 113 is used. However, when the food discharging means 113 is used before the cooling operation means 40, the pressure drop due to the sealing member inside the food P and the carbonated food container 20 prevents the relaxation of the food container side wall 100. And thus impair the integrity of the seal formed by the dry gas seal 123 between the inner sleeve member 102 and the cover sleeve member sidewall 101, and a slight leanness of the dry gas GS will result in the drying gas chamber ( It is expected that it will cause a pressure difference between the DGS) (low pressure) and the humidified liquid chamber w. In either case of the cooling operation means 40, the humidification liquid HL will naturally cause the humidification liquid vapor Vw from the humidification liquid chamber W to evaporate into the drying gas chamber DXS. Slight thinning of the drying gas GS will cause a pressure difference between the drying gas chamber DGS (low pressure) and the humidified liquid chamber w. In any case of the cooling operation means 40, the humidified liquid vapor Vw will naturally evaporate due to the pressure difference between the drying gas chamber DGS and the humidified liquid chamber W and flow into the drying gas chamber DGS. . It starts the cooling process by evaporating the humidified liquid vapor (Vw) into dry gas (GS). The same is true when the food discharging means 113 is used before the cooling operation means 40. When the carbonation pressure in the food (P) is released, the holding power of the dry gas seal 123 on the side wall 100 of the food container is weakened, and a slight dilution of the dry gas GS is caused by the drying gas chamber (DGS) (low pressure) and humidification. It will cause a pressure difference between the liquid chambers w. In either case of the cooling operation means 40, the humidified liquid vapor Vw will be forced to enter the drying gas chamber DGS naturally. The humidified liquid vapor Vw is passed into a drying gas chamber DGS having a drying gas DG therein. The dry gas chamber (DGS) is expected to contain compound (S) therein. This causes additional endothermic cooling. The drying gas GS evaporates the humidification liquid HL into the humidification liquid vapor Vw, and evaporative cooling occurs. The drying gas (DG) absorbs the humidified liquid vapor (Vw) to lower the dew point temperature of the drying gas (DG) and becomes a wet gas. The heat of evaporation H is removed by the drying gas as the drying gas DG becomes wet and its dew point temperature decreases. As before, the plastic heat-shrinkable vapor absorber (D) is heated while absorbing the humidified liquid vapor (Vw), and the annular plastic heat-shrinkable vapor absorber holding space wall 133 stretched by elongation molding increases in temperature due to deformation and area reduction. Reacts to

As before, when heated, the annular plastic heat-shrink vapor absorber holding space wall 133 contracts the surface area and moves outward away from the food container domed lower wall 22, so that the volume of the drying gas chamber (DGS) is reduced. Increase, thus creating a substantially low vapor pressure in a fixed amount of lean dry gas DG within the drying gas chamber DGS. This lowers the vapor pressure of the drying gas DG in the drying gas chamber DGS. The pressure in the drying gas chamber (DGS) is now lowered so that the humidified liquid vapor (Vw) is pulled into the drying gas chamber (DGS) at an accelerated rate. This deformation of the annular plastic heat shrink vapor absorber holding space wall 133 continues with the continuous generation of more evaporation heat h, so that the annular plastic heat shrink vapor absorber holding space wall 133 tends to be preferably flat. So that the volume of the drying gas chamber (DGS) is increased compared to the original volume. Deformation and planarization of the annular plastic heat shrink vapor absorber holding space wall 133 increases the volume of the drying gas chamber (DGS), and because there is a fixed amount of drying gas (DG) in the drying gas chamber (DGS), drying A lower pressure is created inside the gas chamber DGS. The annular plastic heat-shrink vapor absorber holding space 131 is also made larger by the planarization of the annular plastic heat-shrink vapor absorber holding space wall 133. As before, this causes the plastic heat-shrink vapor absorber D to continuously move, move, fall and diffuse over the flat annular plastic heat-shrink vapor absorber holding space wall 133. This diffusion agitates the plastic heat shrink vapor absorber (D) and makes it more effective because it has a larger surface area. Thus, the drying gas DG is a means of electromotive heat transfer into the plastic heat-shrinkable vapor absorber D of the humidified liquid vapor Vw which does not require vacuum.

The combination of humidifying liquid (HL) and plastic heat-shrink vapor absorber (D) is summarized in Table 1 below.

FIG. 16 is a third implementation having a dry gas seal 123 positioned about the middle of the food container side wall 100 to make space above the humidified liquid chamber to hold the dissolved compound (DCC) above the dry gas seal 123 Another version of the form is shown. 16 also shows an outwardly heat-shrinkable protrusion 141 that forms the lower wall of the inner sleeve member 102. The heat-shrinkable protrusion 141 increases the volume of the drying gas chamber DGS and decreases the volume of the humidification liquid chamber W when heated by the plastic heat-shrink vapor absorber D. This is an example of an outer protruding structure. It acts as a pump for the humidification liquid (HL) to rise and interact with the soluble compound (DCC) to provide endothermic cooling by solvation. At the same time, the drying gas (DG) will cause the humidification liquid (HL) to evaporate into the humidification liquid vapor (Vw), which will cause more cooling by evaporation. Therefore, by controlling the amount of humidifying liquid (HL) pumped into the soluble compound (DCC) and the evaporation rate of the humidifying liquid (hl), drying and dissolution of the soluble compound (DCC) requires repeated cooling using the same amount of chemical substances. It can be adjusted to repeat the solvation process and cooling to provide.
