Definitions
- the present novel invention relates generally to the art of cooling food and beverage food product containers and to processes for manufacturing such food product containers. More specifically the present invention relates to food and beverage food product containers for cooling a food product such as a beverage; methods of cooling said food products; and methods of assembling and operating the apparatus.
- the terms "beverage,” “food,” “food products” and “food product container contents” are considered as equivalent for the purposes of this application and used interchangeably.
- the term “food product container” refers to any sealed and openable storage means for a food product meant for consumption.
- beverage food product container devices for cooling the contents of a beverage or other food beverage food product container. These devices sometimes use flexible and deformable receptacles or rigid receptacle sides to store a refrigerant for phase change cooling.
- Some prior art devices use desiccants with a vacuum activated to evaporate water at low pressure and absorb vapor into a desiccant.
- Other prior devices use refrigerants stored between pressure vessels in liquid phase to achieve the cooling by causing a phase change of refrigerants from a liquid to a gaseous state. The present inventor has invented a variety of such devices and methods of manufacturing them.
- Prior art that uses liquefied refrigerants fail to address the real issues of manufacturing and 10 beverage plant operations that are crucial for the success of a self-cooling food product container program.
- Some such prior art designs require pressurized food product containers to store liquid refrigerants.
- 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 difficulty in implementation of such technologies.
- cryogenic refrigerants such as co 2
- All such prior art designs require very highly pressurized food product containers to store the cryogenic refrigerants.
- Some technologies that promise to use co 2 have implemented carbon traps such as activated carbon, and fullerene nanotubes to store the refrigerants in
- Desiccant-based self-cooling food product containers require the desiccant to be stored between a premade vacuum. When the vacuum is released between the two compartments, water vapor is pulled 5 into the vacuum and then absorbed by the desiccant and heat of evaporation is taken from the cooled item and transported to condense in the desiccant. The heat taken by the evaporated water heats up the desiccant and must not be allowed to interact with the beverage, otherwise it would heat up the beverage again. It is very difficult to maintain a true vacuum in the desiccant chamber and in a water reservoir. Further, the valves and activation devices used by prior art require stiff pins, knives and so on. The 10 vacuum must be maintained for a long period of storage and can sometimes fail.
- US Patent number 5,983,662 uses a sponge in place of a desiccant to cool a beverage.
- Prior endothermic self-cooling food product containers depend on the stoichiometric mixture of a fixed amounts of chemicals to achieve a fixed amount of cooling. After the cooling process, the thermodynamic transport mechanism and potential to cool is exhausted and no further cooling can take place. Further, the products of the reaction remain as caustic and acidic components in the form of bases and acids that can be harmful.
- us patent application pub. No: US 2015/0354885 AL shows a system for externally cooling a beverage containing a specific amount of beverage.
- the system comprises a cooling housing having an inner wall and an outer wall, the inner wall being of thermally conductive material contacting at least a part of the beverage holder, the cooling housing defining an inner compartment including at least two separate, substantially non-toxic reactants, causing, when reacting with one another, a non-reversible, entropy-increasing reaction producing substantially non- toxic products in a stoichiometric number at least a factor 3 larger than the stoichiometric number of said reactants, said at least two separate substantially non-toxic reactants initially being included in said inner compartment separated from one another and causing, when reacting with one another in said non- reversible, entropy-increasing reaction, a heat reduction of said beverage within said beverage holder.
- the present invention differs from all the mentioned prior art and provides a novel cost effective and thermodynamically simple and viable heat transport means for cooling a beverage in a food product container by renewing the cooling potential of fixed amounts of reactants using electromotive regeneration of a dry gas. Many trials and designs have been made to obtain the present configuration of the disclosed invention.
- the present invention overcomes this deficiency by means of an extremely dry gas. Dry gas with a dew point of 10°f to -150°f can easily absorb vapor from a liquid that is cooled to freezing point. The dry gas simply increases its dew point temperature, while the actual thermometric temperature of the dry gas itself remains constant.
- a fixed amount of cooling can be achieved by irreversibly combining a fixed amount of water with a fixed amount of ionizable compounds Such as chlorides and nitrates.
- ionizable compounds such as chlorides and nitrates.
- the solvation products of endothermic reactants can result in acidic solutions and basic products such as hydrochloric acid and sodium hydroxide obtained from the dissolution of ions of potassium chloride in water.
- the prior art requires impervious metals to be used for the desiccant and the water chamber due to the need to sustain a true vacuum over a long period of time.
- the parts of the apparatus surrounding the food product Preferably are made from heat-shrinkable plastic materials such as injection stretch blown polyethylene tetraphthalate (PET) and shrinkable poly vinyl chloride (PVC), which are inexpensive materials interacting with a standard aluminum or steel food product container.
- PET injection stretch blown polyethylene tetraphthalate
- PVC shrinkable poly vinyl chloride
- the present invention bypasses the stoichiometric limitations of common methods of cooling a product by endothermic reactions and also bypasses the need for a true vacuum and other deficiencies and goes directly into the properties of electromotive vapor and heat transport means using a dry gas in a low vapor pressure state with dew point temperatures in the range 15 10°f to -l50°f as well as the properties of materials used acting in a beneficial manner.
- Prior desiccant technologies need to store a permanent true vacuum to evaporate water at low pressure and cause cooling.
- the present invention bypasses this step of storing a vacuum in desiccant processes and utilizes the physical properties of the materials used by the >0 invention to create a rarefication of dry gas only when required. Dry gas starts the process of evaporation and the process of evaporation is enhanced by rarefication of the dry gas.
- the materials used to manufacture the present invention are preferably made from a combination of heat-shrinkable plastic materials, such as injection stretch blown heat- shrinkable polyethylene tetraphthalate (PET) and heat-shrinkable poly vinyl chloride (PVC), which are inexpensive materials interacting with a standard aluminum or steel food product container.
- PET injection stretch blown heat- shrinkable polyethylene tetraphthalate
- PVC heat-shrinkable poly vinyl chloride
- heat-shrinkable materials allow them to perform mechanical functions when subjected to the heat of evaporation and actually do mechanical 5 work from this heat by expanding the dry gas chamber’s volume to generate a rarefication of the dry gas by means of the heat-shrinkable physical properties of said material.
- aluminum can be used in many parts of its construction, particular features used for rarefication of the dry gas require such heat-shrinkable plastic materials b)
- desiccant processes in prior art generate 100% partial vapor pressure of the 10 evaporant such as water in the cooling chamber when the vacuum is exposed to the cooling chamber. This presents problems. The water vapor evaporated by the vacuum reduces the vacuum and stops the process until the desiccant starts again to reduce the vapor pressure in the cooling chamber. Thus the process depends on the rate of absorption of vapor by the desiccant.
- the water vapor evaporated by the vacuums of prior art fills the cooling chamber and can contact the cooling surfaces and condense to transfer heat of condensation from one section of said cooling chamber to another.
- the minimum operating temperature of the evaporated vapor is 32°f, which is the freezing point of water.
- the dry gas system used by the present invention has dew point temperatures in the range l0°f to -150°f, which is below >0 the freezing point of water, and thus the evaporation of water vapor into dry gas is not hampered by cooling and icing.
- the dry gas dew point temperature is increased by evaporation, but does not heat up the cooling chamber
- a plastic heat-shrinking vapor absorber technology is used by some embodiments of the present invention.
- a dry gas is used to absorb humidification liquid vapor from compartments made by an internal sleeve member that can be at ice-cold temperatures while lowering the dry gas’s dew point temperature (not its temperature).
- this humidification liquid vapor is not readily available to the cooling surfaces for condensation.
- the humidification liquid vapor is held by the low vapor pressure of the dry gas, and thus will not condense back on cooling surfaces.
- the plastic heat-shrinking vapor absorber absorbs the vapor from the dry gas and the need for a true vacuum is eliminated. Thus any humidification liquid can be used.
- a humidification liquid such as dimethyl ether which is a pressurized liquid can be used but can give off vapor that can be absorbed by a dry gas instantly.
- the dry gas acts as a locomotive vapor pressure cascade conductor for transferring vapor from the liquid phase to the plastic heat-shrinking vapor absorber using an electromotive potential.
- the plastic heat-shrinking vapor absorber which interacts with the electromotive nature of dry gas more readily than with the direct vapor.
- standard desiccants in air conditioners that use desiccant- wheels use the advantages provided by a dry gas to move moisture and regenerate. This is not done in a vacuum.
- the present invention uses a plastic heat-shrinking vapor absorber’s heat to activate the physical properties of a plastic heat-shrinking vapor absorber chamber wall that is specially designed to alter its shape to generate and create a rarefication in by increasing the volume of the dry gas chamber in which a fixed amount of dry gas is stored. Thus there is no need to store a permanent vacuum and a true vacuum is not required.
- the present invention uses deformable simple seals comprising sealing ring structure made of one of a suitable O-ring seals, metal band seals, rubber band seals, putty seals, and sealing waxes seal to cause actuation and perform a sealing function and thus the present invention does not necessarily require pins, knives and other methods to introduce water vapor to the plastic heat-shrinking vapor absorber, even though they may still be used. There is no worry about a loss of vacuum during storage. As such the plastic heat-shrinking vapor absorber and the subcategory of vapor absorbers used in the invention do not necessary have to have the best affinity for the humidification liquid vapor of the humidification liquid used. Instead they are optimized for delivery of said humidification liquid vapor by dry gas. Thus while prior inventions require desiccants that are fine tuned for pure vapor absorption, the present invention fine tunes the vapor absorber for absorption of vapor from a dry gas.
- Dry gas such as substantially dry air, substantially dry C0 2 , substantially dry nitrogen, and other substantially dry gases with a very low dew point temperature can cause extreme cooling as is evidenced by weather patterns that are predominantly driven by the humidity of air and heat energy available in the atmosphere.
- dry air can result in dramatic snow and ice formation, in turn resulting in extreme weather patterns across the world.
- lip-balm used for dry lips sells well in winter. From hurricanes to tornadoes, to heavy snow storms, and icy winter storms, nature has provided an amazing electromotive heat transport means that can be emulated to assist in cooling a beverage and a food product using humidification and dehumidification of air.
- Water has the best thermodynamic potential to cool a food product. It has the highest heat of evaporation and as such it can be used in combination with electromotive drying and regenerative processes that also rely on water molecules to cool a food product container. However, water does not easily evaporate due its high heat of evaporation and as such it must be“enticed” to do so by an appropriate means. Further, as water cools, for example in an endothermic reaction, and in a desiccant evaporation system, it becomes more and more difficult to evaporate it. Thus, neither endothermic cooling nor conventional desiccant cooling systems of prior art by themselves prove to be the most efficient forms of cooling a food product such as beverage. The combination of dry gas mediation, and other cooling methods can use the two fundamental substances, water and dry gas to effectively increase the thermodynamic potential to cool a food product.

- Annular plastic heat- shrinking vapor absorber retention space is a stretch-formed heat-shrinkable portion of covering sleeve member. If covering sleeve member is made from aluminum, then covering sleeve member annular wall must be made as a separate item made from one of heat-shrinkable PET and heat-shrinkable PVC and the attached by a suitable glue to the covering sleeve member bottom wall.
- the covering sleeve member annular wall responds to an increase in temperature by deforming and shrinking and flattening to increase the volume of the dry gas chamber. This deformation is caused by the plastic heat-shrinking vapor absorber heating up as it absorbs humidification liquid vapor from the dry gas.
- the covering sleeve member annular wall preferably forms a shape that intrudes into the volume of the dry gas chamber.
- the protruded shape of the covering sleeve member annular wall is important in enhancing the functioning of the apparatus.
- the shape of covering sleeve member annular wall can be an inverted cup, a dome, and preferably any suitable shape that minimizes the volume of the equivalent cylindrical volume formed by just the covering sleeve member side wall with a flat bottom.
- the shape of covering sleeve member annular wall must initially minimize the dry gas chamber’s volume and then maximize its intrusion into the dry gas chamber when heated.

- the annular plastic heat-shrinking vapor absorber retention space is in fluid communication with dry gas.
- the plastic heat-shrinking vapor absorber heats up the covering sleeve member annular wall.
- the covering sleeve member annular wall shrinks and minimizes its area.
- the annular plastic heat-shrinking vapor absorber retention space contracts and moves outwardly from the food product container domed bottom wall and causes the volume of the dry gas chamber to increase and generate a substantial negative pressure on dry gas. This lowers the partial vapor pressure of the dry gas and the partial vapor pressure of any humidification liquid vapor in the dry gas chamber and thus in the internal sleeve member.
- internal sleeve member may also be made from one of pressure-formed and deep drawn aluminum. It is anticipated that the internal sleeve member side wall can be layered with a wick material that is made to just hold humidification liquid without spilling the same when it receives it.
- the inward facing protuberances and the outward facing protuberances can be formed by first making the internal sleeve member side walls as a cylinder, then placing its cylindrical wall over a mold and heat-shrinking it to form the inward facing protuberances and the outward facing protuberances.
- the inward facing protuberances tangentially touch the food product container side wall and the outward facing protuberances form a multitude of compartments with the food product container side wall to hold either chemical compounds or humidification liquid against the food product container side wall.

- the internal sleeve member can be heat-shrunk to form its shape by hot-spraying it with a stream of particulates of ionizable chemical compounds at high impact pressure as it is ’ thermally shrunk to form its shape on a mold.
- the internal sleeve member must have a vapor passageway formed by its outer surface walls and the covering sleeve member side wall to only allow vapor to pass through to the plastic heat-shrinking vapor absorber. This is easily achieved in the case of a film material forming the internal sleeve member by banding a vapor wicking material over the internal sleeve member restriction portion.
- ionizable soluble salts include using a soluble material such as poly vinyl acetate (PVA), layered on the outside wall of the internal sleeve member and then attaching the ionizable chemical compounds to the PVA layer.

- the dry gas can be stored at moderate pressure at room temperature. Dry gas can be easily manufactured using either a pressure precipitation system, and by using a cooling system, or a desiccant stack to remove humidification liquid vapor from the wet gas. Dry gas when stored within the dry gas chamber, acts as if said dry gas chamber is evacuated for the purposes of humidification liquid introduced to said dry gas chamber. This is because dry gas has such a low humidification liquid vapor pressure that it can be said to be a vacuous partial humidification liquid partial vapor pressure.
- a dry gas cools by absorbing humidification liquid vapor from its environment in the same manner that water evaporates when exposed to a vacuum.
- a dry gas carries humidification liquid vapor within its molecular structure as electrostatically bound vapor, it does not allow easy condensation of humidification liquid vapor on surfaces that are above its dew point temperature. This results in a heat transport means that can be understood if one compares what happens to an evacuated gas and its temperature relations to pressure. Dry gas has component molecules of moisture that can only exert a low partial humidification liquid vapor pressure and acts as if it’s vapor is in a vacuum.
- This interstitial molecular sieving of dry gas’s potential is a measure of its relative dew point temperature with respect to humidification liquid vapor which like an evacuated gas in a negative temperature in relation to wet gas at room temperature.
- the partial vapor pressure of the humidification liquid vapor in dry gas is very low, and as such the moisture behaves as if it is suspended in a vacuum when exposed to dry gas.
- any action performed by a dry gas in the practice of this invention is equivalent to actions that take place in an evacuated environment for humidification liquid vapor except for the fact that a vacuum environment will evaporate humidification liquid and humidification liquid vapor may condense on cold surfaces that are cooler than the vapor’s temperature.
- Dry gas is an electromotive transport means.
- Dry gas essential is therefore superior to a vacuum when it comes to the evaporation of humidification liquid and there is a low partial humidification liquid vapor pressure at any achievable surface temperature of a cooling device especially if the dry gas relative dew point with respect to humidification liquid vapor is in the range below the formation of a solid from the humidification liquid.
- This invention can in one mode use far less ionizable compounds (67g) in one mode with lOOg of humidification liquid and regenerate the ionizable compounds for reuse.
- ion exchange compounds and other types of electrochemical and electromotive membranes such as PEM, absorb water vapor and preferentially cool by transmitting protons through their structure, converting liquid to transmitted vapors.
- the internal sleeve member can be manufactured from similar materials such as ion exchange film materials to act in a similar fashion transmitting water formed by reactions of the chemicals in the humidification liquid chamber to further cool.
- the dry gas in the dry gas chamber can interact multiple times with humidification liquid vapor in the dry gas chamber to humidify and further cool.

- the cost of manufacture is now only limited by the cost of the covering sleeve member, the cost of the internal sleeve member, the cost of chemical components, and the cost of the processes used to manufacture the apparatus.
- Dry gas can also transport water vapor from cold solutions in an electrolyte invasion process to dehydrate these ionic solutions and allow solutes to be active again for further use of their 10 thermodynamic potential.
- the dry gas will not only cool, but also allow the stoichiometric imbalance of reusing solutes to further perform cooling.
- the invention can be practiced with only dry gas and a dry gas chamber without chemicals.
- the humidification liquid can be generated by the chemical reactions of water donating hydrated chemicals in the dry gas chamber. This produced humidification liquid can be evaporated and absorbed by the dry gas to further cool. Further, the plastic 15 heat-shrinking vapor absorber keeps the dry gas dry within the dry gas chamber.
- Humidification liquid vapor absorbed by dry gas can be sorbed into plastic heat-shrinking vapor absorber to lower the vapor pressure of the humidification liquid chamber and cause further evaporation and cooling of the humidification liquid held between the internal sleeve member and the food product container side wall, which in turn cools the food product.

- the dry gas valve DGV at a low pressure of about lpsig and the vacuum valve Vv are first opened to allow dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the covering sleeve member 30 using the vacuum pump VP. After a few seconds of purging, the dry gas valve DGV is turned off to allow the vacuum pump VP to lightly rarify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure.

- the dry gas valve DGV and the vacuum valve Vv are shut off and the humidification liquid valve HLV is opened to allow humidification liquid HL to fill the annular space above the dry gas seal 123 between the food product container side wall 100 and the covering sleeve member side wall 101 up to a level just below the covering sleeve member seal 121 and then it is shut off.
- Hot air HA from the heat source HG is now directed on the location of the covering sleeve member sealing portion 108 to shrink and clamp the covering seal 121 against the food product container side wall 100 after which the hot air HA is removed.
- the cooling actuation means Q is activated before the food product release means 113 is used. However, should the food product release means 113 be actuated before the cooling actuation means Q, then it is anticipated that the pressure drop of the food product container 20 will cause a relaxation of the food product container side wall 100 and slacken the dry gas seal 123 relative to the food product container side wall 100 and thus the apparatus 10 can be still activated as shown in FIGURE 10 by simply applying finger pressure 40 and pressing upon the covering sleeve member side wall 101 in the region of the dry gas seal 123 to deform the dry gas seal 123 and the food product container side wall 100 and allow the humidification liquid HL to leak into the dry gas chamber DGS.
- Humidification liquid HL enters between the outward facing protuberances in the and dissolves the ionizable chemical compounds S held in them. This causes a first endothermic cooling of the humidification liquid HL.
- the humidification liquid HL also saturates internal sleeve member side wall 105 and the wick 140 absorbs the humidification liquid.
- the dry gas DG absorbs humidification liquid vapor Vw from the wick 140 and the evaporation of the same causes a second further cooling of the humidification liquid HL. Further, a third cooling is achieved when the solution formed by the species of the dissolving chemical compounds DCC of the chemical compound S, and the humidification liquid is dried out by evaporation of the humidification liquid HL into the dry gas GS.
- the heat of evaporation H is taken away by the dry gas DG as it becomes wet and lowers its dew point temperature. Note that the dry gas DG temperature does not increase by this process since its dew point temperature takes the heat of evaporation h of the humidification liquid HL away.
- the higher dew point temperature dry gas DG saturates the dry gas chamber DGS, and enters the restricted vapor passageway l29a.
- Dry gas DG is an electromotive transport means. The removal of polar water molecules in vapor form into dry gas DG is due to an electromotive heat transport potential. Dry gas DG changes the reactivity of the restricted vapor passageway 129a, (respir. Physiol. l997jul;109 (l):65- 72). Negative ions in a dry gas DG attract polar molecules of the humidification liquid HL in the restricted vapor passageway l29a. This is why when air is dry, one gets a greater propensity for electrostatic effects.
- the plastic heat-shrinking vapor absorber D may be one of, a liquid, gel, and a solid that absorbs humidification liquid HL vapor Vw.
- Humidification liquid HL may also be a pressurized liquid in equilibrium with its vapor such as an ammonium solution, a dimethylether solution, and a carbonated solution.
- table 1 provides for the various combinations of the plastic heat-shrinking vapor absorber D, the dry gas GS, and the humidification liquid HL that may be used with the invention.
- Plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being pre-stretch-formed, responds to the increase in its temperature by deforming and shrinking in area.
- the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks in surface area and moves outwardly from the food product container domed bottom 22 causing the volume of the dry gas chamber DGS to increase and thus generate a substantial lower vapor pressure in the fixed amount of rarified dry gas DG in the dry gas chamber DGS.
- support cylinder 132 takes up the compressive forces of the annular plastic heat-shrinking vapor absorber retention space wall 133 against the food product container bottom edge 21 and prevents the covering sleeve member bottom wall 130 from deforming.
- the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 will not affect the structure of the covering sleeve member bottom wall 130.
- the deformation and flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 causes the dry gas chamber DGS to increase in volume, and since there is a.
- the dry gas DG is preferably at atmospheric pressure when it is stored between the dry gas chamber DGS.
- the negative pressure generated on the dry gas DG causes even more absorption of humidification liquid vapor Vw into the dry gas DG by evaporation of humidification liquid HL.
- the approximately 1840-fold expansion of humidification liquid HL into humidification liquid vapor Vw in the dry gas chamber DGS due to the gasification of humidification liquid HL increases the relative vapor pressure of the dry gas chamber DGS in relation to the annular plastic heat- shrinking vapor absorber retention space 131.
- the humidification liquid vapor Vw in the dry gas chamber DGS naturally wants to enter into the plastic heat-shrinking vapor absorber D.
- dry gas DG is an electromotive heat transport means for humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D without the need for a true vacuum.
- dry gas DG delivers the humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D
- its actual temperature increases due to the heat generated by the plastic heat-shrinking vapor absorber D.
- the heat from the plastic heat-shrinking vapor absorber D is partially absorbed by the dry gas DG and its dew point temperature lowers even more. This causes dry gas DG to migrate again into the plastic heat-shrinking vapor absorber D and collect more humidification liquid vapor Vw from dry gas chamber DGS.
- the cooling continues in this fashion dehydrating the ionizable compounds on the dry gas chamber DGS.
- the ionizable compounds are not absolutely necessary for the invention to work, however they improve the cooling efficiency since dry gas DG will absorb humidification liquid vapor Vw from even cold humidification liquid HL.
- the ultimate source of heat of evaporation h is the food product P, which cools by this method“salting” the dry gas chamber DGS by drying out the chemical compounds S back to their original form (if used), makes them reusable for further cooling. Drying out the dry gas DG by the plastic heat-shrinking vapor absorber D makes it also reusable again for further cooling.
- the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the plastic heat-shrinking vapor absorber D to move and spread out to allow unexposed plastic heat-shrinking vapor absorber D to take action and effectuate the sorbing of humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D.
- a heat-absorbing thermal wax 138 such as ordinary candle wax may be placed in the annular thermal wax retention space 136 between support cylinder 132 and the covering sleeve member side wall 101 to absorb heat of evaporation h from the plastic heat-shrinking vapor absorber D and store the heat of evaporation h.
- this has been found to be effective only if a large amount of plastic heat- shrinking vapor absorber D, is used for a large food product container 20 in excess of 20oz in volume.
- the covering sleeve member 30 can be made from shrinkable material such as TPXTM formed from a combination of plastic materials called Polymethylpentene and glass beads, the resulting covering sleeve member 30 will be capable of quickly releasing absorbed heat of evaporation h through its structure and radiate the heat of evaporation h quickly to atmosphere. Further, the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the atmospheric air in it to absorb heat from the plastic heat-shrinking vapor absorber D and remove this heat through the cardboard hole 137 if used, or directly to the atmosphere as the heated air volume beneath the flattening annular plastic heat-shrinking vapor absorber retention space walls 133 is expelled.

- Cylindrical rod CR is provided as before.
- the humidification liquid valve HLV, the dry gas valve DGV and the vacuum valve Vv are shut off.
- the dry gas valve DGV at a low pressure of about lpsig and the vacuum valve Vv are first opened to allow dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the covering sleeve member 30 using the vacuum pump VP.
- the dry gas valve DGV is turned off to allow the vacuum pump VP to lightly rarify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure.
- Hot air HA from heat source HG is first directed at the location of the covering sleeve member side wall 118 with covering sleeve member sealing potion 119 to heat-shrink it in diameter to form a seal between the covering sleeve member side wall 100 against the dry gas seal 123 and causes the dry gas seal 123 to seal against the internal sleeve member side wall 105, after which the hot air HA is removed.
- hot air HA is then directed at the location of the covering sleeve member sealing portion 108 of the covering sleeve member side wall 101 to shrink and clamp the covering sleeve member sealing portion 108 around the surface of covering sleeve member seal 121 to clamp the same against the food container top wall seam 114 and form a seal, after which the hot air HA is removed.

- Cooling actuation means 40 is activated by using finger pressure f to deform the dry gas seal 123 causing fluid communication between the humidification liquid chamber W and the dry gas chamber DGS. It is anticipated that cooling actuation means 40 is activated before the food product release means 113 is used. However, should the food product release means 113 be actuated before the cooling actuation means, then it is anticipated that the pressure drop of the food product container 20 will cause a relaxation of the food product container side wall 100 and slacken the grip of the dry gas seal 123 relative to the internal sleeve member side wall 105 and thus will cause fluid communication between the humidification liquid chamber W the dry gas chamber DGS and the plastic heat-shrinking vapor absorber D.
- the covering sleeve member side wall 101 can then be massaged by hand relative to the internal sleeve member side wall 105 to cause the reacting chemical compounds RCC in the humidification liquid chamber W to react with each other to endothermically cool and at the same time generate humidification liquid HL.
- the massaging deforms the inward facing protuberances and the outward facing protuberances 104 of the internal sleeve member 102 to allow the reacting chemical compounds RCC to mix and react with each other to provide a first cooling means of the apparatus 10 by endothermic reaction cooling and at the same time provides a means to generate humidification liquid HL for a second cooling means.
- the rarefication of the dry gas GS will force humidification liquid HL thus generated by reactions to evaporate as humidification liquid vapor Vw into the dry gas dg.
- the dry g ts DG absorbs humidification liquid vapor Vw and this lowers the dew point temperature of the dry gas DG and it becomes wet gas in a third cooling means of the apparatus 10. Additional heat of evaporation, h, is taken away from the humidification liquid HL by the dry gas DG as it becomes wet and lowers its dew point temperature.
- the higher dew point temperature dry gas DG saturates the dry gas chamber DGS and is absorbed by the plastic heat-shrinking vapor absorber D in the annular plastic heat-shrinking vapor absorber retention space 131.
- Plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being stretch-formed, responds to the increase in its temperature by deforming and shrinking its area.
- the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks its surface area and moves outwardly away from the food product container domed bottom wall 22 causing the volume of the dry gas chamber DGS and the humidification liquid chamber W to increase and thus generating a substantial lower vapor pressure in the fixed amount of rarified dry gas DG in the dry gas chamber DGS.
- the pressure in the dry gas chamber DGS is now lower and it will absorb more humidification liquid vapor Vw to continue the cooling process.
- the deformation motion of the annular plastic heat-shrinking vapor absorber retention space walls 133 causes the plastic heat-shrinking vapor absorber D to move and spread out to allow unexposed plastic heat-shrinking vapor absorber D to take action and effectuate the sorbing of humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D and a second cooling means is provided by the evaporation of the humidification liquid HL generated by the reactions.

- covering sleeve member shrinkable annular wall 133 shrinks in surface area and tends to flatten with heat received from the plastic heat- shrinking vapor absorber to increase the volume of the dry gas chamber DGS.
- This deformation is caused by the plastic heat-shrinking vapor absorber D heating up as it absorbs humidification liquid HL vapor Vw from humidified dry gas DG in the dry gas chamber DGS.
- the dry gas GS in the dry gas chamber DGS is in fluid communication with the plastic heat-shrinking vapor absorber D and with the restricted vapor passageway H9a and thus, advantageously, the annular plastic heat-shrinking vapor absorber retention space 131 is in fluid communication with the outside walls of internal sleeve member 102.
- covering sleeve member shrinkable annular wall 133 must minimize the dry gas chamber DGS before it is heated, and thus its intrusion into the dry gas chamber DGS must be designed to maximize and increase the volume of the dry gas chamber DGS.
- the shape of the covering sleeve member shrinkable annular wall 133 is an inverted cup. However, it could take on many shapes as shown in the various figures.
- the covering sleeve member shrinkable annular wall 133 shrinks and minimizes its area.
- the annular plastic heat-shrinking vapor absorber retention space 131 expands and move outwardly and causes the volume of the dry gas chamber DGS to increase to generate a substantially lower pressure on dry gas DG less than its initial pressure which preferably is just below ambient atmospheric pressure. This lowers the vapor pressure of the dry gas DG and any vapor in the dry gas chamber DGS, and thus the vapor pressure in the internal sleeve member 102.
- covering sleeve member side wall 100 may be designed with annular protuberances or lateral protuberances to strengthen it and prevent it from collapsing under the rarefication force generated by the plastic heat-shrinking vapor absorber D.
- the inward facing protuberances 103 and outward facing protuberances 104 shown in FIGURE 2 may suffice to provide all the strength and surface area required to support covering sleeve member side wall 100 from the rarefication pressure force generated by the plastic heat-shrinking vapor absorber D.
- the humidification liquid chamber W can be made to just hold enough humidification liquid HL without overflow when it receives it.
- the internal sleeve member l02’s outward facing surface forms a part of the dry gas chamber DGS.
- This surface can also be layered with ionizable compounds S when it is heat shrunk to form its shape by hot-spraying it with a stream of particulates of ionizable compounds carried by heated air at high impact pressure as it is thermally shrunk to form its shape on a mold.
- a dry gas DG at preferably just below atmospheric ambient pressure is provided inside the dry gas chamber DGS and to also fill the dry gas chamber DGS and create a slight pressure difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber W.
- FIGURE 16 shows the apparatus 10 according to the fourth embodiment when the cooling means F is actuated.
- This method is essentially the same as the steps required for the first embodiment with slight differences, a standard food product container 20 is provided.
- a covering sleeve member seal 121 is provided and covering sleeve member seal 121 is expanded and placed circumferentially and tightly around the food product container side wall 100 in a plane parallel to the diametric plane of the food product container 20 and to band around the food product container top wall seam 114.
- dry gas seal 123 is provided and expanded and placed circumferentially and tightly around the food product container top wall 107 about 20mm or so below covering sleeve member seal 121 in a plane parallel to the diametric plane of the food product container 20 to band around the food 5 product container side wall 100.
- Internal sleeve member 102 is provided in the form of a cup-sleeve as described earlier is provided to frictionally encases and fits over food container side wall 100 and just cover the dry gas seal 123. As before a wick 140 is optionally provided and bonded to the outward facing wall of internal sleeve member side wall 105.
- Humidification liquid HL is poured into internal sleeve member 102 to fill the humidification liquid chamber W between the food product container and the internal sleeve member 102 up to just below the dry gas seal 123.
- Hot air HA is first directed at the internal sleeve member 102 at location of the dry gas seal 123 to shrink and clamp the internal sleeve member 102 in part around the surface of dry gas seal 123, after 15 which the hot air HA is removed.
- covering sleeve member 30 is provided as cup-like structure with straight covering sleeve member side wall 101 as shown in FIGURE 2.
- covering sleeve member side wall 101 should be taller than food product container
- the covering sleeve member side wall 101 just fits over the internal sleeve member 102.
- support cylinder 132 is placed to sit on covering sleeve member bottom wall 130 with support cylinder holes 137 close to the food product container 20 to form the annular plastic heat- shrinking vapor absorber retention space 131 and the annular thermal wax retention space 136.
- thermal wax 138 is placed to fill the annular thermal wax retention space 136 and holds a plastic heat-shrinking vapor absorber D is filled in the annular plastic heat-shrinking vapor absorber retention space 131.
- cylindrical rod CR is provided with a through hole TH through its length and with a three-way fitting TF W attached to the through hole TH.
- TF W the first input of the three-way fitting
- TFW is connected by a dry gas hose DGH to fluidly communication with dry gas pressure canister DGC via a dry gas valve DGV.
- the second input of the three-way fitting TFW is connected by a vacuum pump hose VPH to a vacuum pump VP via a vacuum valve Vv.
- the third input of the three-way fitting TFW is connected by a humidification liquid tank HLT via a humidification liquid valve HLV.
- the cylindrical rod CR outer diameter is made to fit exactly inside the covering sleeve member 30 and it is inserted about 20mm into the open end of covering sleeve member 30 and covering sleeve member 30 is heat shrunk to seal around it.
- the humidification liquid valve HLV, the dry gas valve DGV and the vacuum valve Vv are shut off.
- the dry gas valve DGV regulated at a low pressure of about lpsig and the vacuum valve Vv are first opened to allow dry gas GS to flood the interior of the covering sleeve member 30 to purge any wet air and gases within the internal sleeve member 102, the dry gas chamber DGS and in the interior of the covering sleeve member 30 using the vacuum pump VP.
- the dry gas valve DGV is turned off to allow the vacuum pump VP to lightly ratify the dry gas DG remaining in the covering sleeve member 30 to a pressure just below ambient atmospheric pressure.
- a cut off valve to control the pressure may be provided, but the vacuum pump VP itself can be made to provide the rarefication required.
- Hot air HA from the heat source HS is now directed on the location of the food product covering sleeve member sealing portion 108 of the covering sleeve member side wall 101 to shrink and clamp around the covering seal 121 after which the hot air HA is removed. This seals and forms the dry gas GS in the dry gas chamber DGS.
- the extra material of the covering sleeve member 30 that is attached to the cylindrical rod 10 CR is cut off to create the covering sleeve member side wall end 110.
- the apparatus 10 is now ready for use.
- the cooling actuation means 40 is activated by finger f pressure to deform dry gas seal 123 before the food product release means 113 . is used.
- the pressure drop due to the absence of a seal in the food product P and also within a carbonated food product container 20 will cause a relaxation of the food product container side wall 100 and thus compromise the integrity of the seal formed by dry gas seal 123 between the internal sleeve member 102 and the covering sleeve member side wall 101 and the slight rarefication of the dry gas GS will cause a pressure >0 difference between the dry gas chamber DGS (lower pressure) and the humidification liquid chamber w.
- Humidification liquid vapor Vw passes through into the dry gas chamber DGS which has dry gas DG in it.
- the dry gas chamber DGS is anticipated to contain chemical compounds S within it. This causes further endothermic cooling.
- Dry gas GS evaporates the humidification liquid HL into humidification liquid vapor Vw and evaporative cooling occurs.
- the dry gas DG absorbs humidification 15 liquid vapor Vw and this lowers the dew point temperature of the dry gas DG and it becomes wet gas.
- the heat of evaporation, H is taken away by the dry gas DG as it becomes wet and lowers its dew point temperature.
- the plastic heat-shrinking vapor absorber D heats up as it sorbs the humidification liquid vapor Vw and the annular plastic heat-shrinking vapor absorber retention space wall 133 which is tensioned by being stretch-formed, responds to the increase in its temperature by >0 deforming and shrinking its area.
- the annular plastic heat-shrinking vapor absorber retention space wall 133 shrinks its surface area and moves outwardly away from the food product container domed bottom wall 22 causing the volume of the dry gas chamber DGS to increase and thus generating a substantial lower vapor pressure in the fixed amount of rarified diy gas DG in the dry gas chamber DGS. This lowers the vapor pressure of the dry gas DG in the dry gas chamber DGS. The pressure in the dry gas chamber DGS is now lower and thus humidification liquid vapor Vw is pulled into the dry gas chamber DGS at an accelerated rate.
- This deformation of the annular plastic heat-shrinking vapor absorber retention space wall 133 continues with the continued generation of more heat of evaporation h and causing the annular plastic heat-shrinking vapor absorber retention space wall 133 to tend to flatten and thus increase the volume of the dry gas chamber DGS relative to its original volume.
- the deformation and flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133 causes the dry gas chamber DGS to increase in volume, and since there is a fixed amount of dry gas DG in the dry gas chamber DGS, a lower pressure is created inside the dry gas chamber DGS.
- the annular plastic heat-shrinking vapor absorber retention space 131 is also made larger by the flattening of the annular plastic heat-shrinking vapor absorber retention space wall 133. As before, this causes the plastic heat- shrinking vapor absorber D to continuously shift, move, fall, and spread over the flattened annular plastic heat-shrinking vapor absorber retention space wall 133. This spreading agitates the plastic heat- shrinking vapor absorber D and makes it more effective as it assumes a greater surface area.
- dry gas DG is an electromotive heat transport means for humidification liquid vapor Vw into the plastic heat-shrinking vapor absorber D without the need for a vacuum.
- FIGURE 16 shows yet another version of the third embodiment with the dry gas seal 123 positioned about midway on the food product container side wall 100 to make room above the humidification liquid chamber to hold dissolving chemical compounds DCC above the dry gas seal 123.
- FIGURE 16 also shows an outwardly heat-shrinkable projection 141 that forms the bottom wall of the internal sleeve member 102.
- Heat-shrinkable projection 141 is an example of an outward projecting structure relative to the food product container 20 that increases the volume of the dry gas chamber DGS when heated by plastic heat-shrinking vapor absorber D, while at the same time it decreases the volume of the humidification liquid chamber W.
- the drying and dissolving of the dissolving chemical compounds DCC can be regulated to provide for a repeated cooling using the same amount of the chemicals to repeat the solvation process and cooling.
