摘要:
The invention is directed to a low-temperature cooler using dry ice as a cooling agent. The cooler has two compartments, one for the dry ice and one for chilled storage. The cooler self-regulates via an aqueous filled temperature-regulating valve to maintain a desired temperature in the storage compartment such that the products stored therein are stored at an optimum temperature. Upon achieving a predetermined temperature in the storage compartment, the valve closes, thereby maintaining the predetermined temperature in the storage compartment.

A portable beverage container assembly includes a capsule containing a refrigerant which is inserted into and securely held inside the beverage container, together with a mechanism to discharge the refrigerant so that the latent heat of evaporation and expansion of the refrigerant gases will impart a chilling action to the refrigerant and hence to the beverage inside the container when the user wishes to drink the beverage.

The present invention is directed to a method for charging a self-chilling beverage can, in a self-chilling beverage can of the type involving a container-within-container construction wherein, for example, a granular carbon material is contained within the inner container, and charged with a gas that is absorbed into the carbon material under pressure, the beverage being placed into the space between the inner and outer containers, and further whereupon release of the charging gas, the temperature of the carbon material drops rapidly, enabling a transfer of heat from the contained beverage through the wall of the inner container into the carbon material. The present invention is directed to a method for providing accelerated charging of the charging gas into the inner container, while absorbing and/or transporting away heat generated by the compression of the charging gas. The invention is also directed to an apparatus for facilitating charging of such a self-chilling container. The present invention is also directed to a self-heating container.
摘要:
A self cooling beverage container or can. Different embodiments of a self cooling can are shown including the use of an endothermic reaction perhaps between ammonium nitrate and water. In another embodiment a volatile liquid is evaporated. In another embodiment water is maintained in a low pressure environment and allowed to boil. The vapour which is produced from the boiling water is absorbed by a desiccant maintaining the boiling process. The cooling process may be initiated by the pressure release of a carbonated beverage can during opening of the can.

A receptacle for maintaining perishables, such as food, at a reduced temperature features an exterior shell joined to an interior shell so that a space occupied by a vacuum exists between them. The junction of the inner and outer shells is located on the exterior of the receptacle. Phase change material is disposed within compartments in the bottom of the receptacle and is covered by a false bottom. A cryogenic liquid, such as liquid nitrogen, is poured down the interior walls of the receptacle and into the compartments containing the phase change material so that the phase change material is frozen in situs. A liquid absorbing material may be substituted for the phase change material.

A cooling system built into a drinking mug. The mug contains a cooling ribbon spirally wound about the interior beverage holding area of the mug. A mobile cylinder container interconnects the ribbon channel with a replaceable nitrogen gas cartridge housed in a vacuum chamber located in the bottom of the mug. The cooling system is hand activated by a spring-loaded mechanism which moves the mobile cylinder container into and out of engagement with the ribbon channel. This arrangement buffers the ribbon channel from the gas cartridge and ensures that only measured amounts of the cooling gas from the gas cartridge are inserted into the ribbon channel. This arrangement also provides a means for supplementing the amount of cooling gas in the ribbon channel.

A self-cooling fluid container includes a fluid chamber for containing the fluid-to-be-cooled. A refrigerant chamber, containing a pressurized refrigerant, is integral with the base of the fluid chamber and extends at least partially into the fluid chamber. The interior region of the refrigerant chamber is fluidicly isolated from and thermally coupled to the interior region of the fluid chamber. A refrigerant dispersal assembly defines a vented dispersal region including a portion adjacent to the refrigerant chamber and separated from the interior of that chamber by a perforatable wall. A cooling activator is adapted to selectively form a fluidic path from the interior of the refrigerant chamber to the dispersal region through the perforatable wall, permitting release and expansion of the pressurized refrigerant.

The present invention relates to the use of a pop top mechanism of a disposable beverage container which includes a lance in the pop top lever which can be pressed downwardly to penetrate the top of the container allowing a refrigerant inside the container to be released into the atmosphere thereby cooling the contents of the container by evaporation of the refrigerant coolant.
摘要:
A beverage can be cooled to a temperature lower than the ambient temperature by canning said beverage within a can which is internally provided with an integral cooling system comprising a compartment containing a liquid refrigerant fluid such as Freon 22 under a relatively elevated pressure, a compartment under reduced pressure connected with said high pressure refrigerant compartment by means of a partition, and a partition breaking device for perforating said partition to permit the expansion and flashing of the refrigerant fluid into said compartment under reduced pressure, in order to produce an absorption of heat from said beverage by the evaporation of said liquid refrigerant.
