Abstract
A unique system to insulate and retain the cold temperature of products, liquids, or materials of any type or nature. In the preferred embodiment, the system comprises a series of layers of material as follows: (1) a hard, durable plastic layer of polyvinyl chloride or similar material; (2) a layer of retardant aluminum; (3) a layer of styrofoam; (4) a layer of neoprene; (5) a cavity which is filled with dry ice through an input valve at the top of the system and which is purged through an escape or purge valve at the bottom of the system; the layers completely surround and envelope the cavity such that one closed system is created. The system could be made in any of many shapes and sizes to accommodate various industries, for example, the system constructed in the outer shape of a beer keg could constitute a jacket, which would be removable with hinges and buckles to keep kegs cold for up to 96 hours without refrigeration or ice. The system could be constructed in the appropriate shape and size for use in the emergency medical industry to transport vital organs or items which must be kept cold without the use of refrigeration. The system could be used to keep food products frozen during transportation. The concept would eliminate, in many applications, the need for refrigeration which would decrease consumption of electricity and which would have positive environmental effects by eliminating the use of freon and other chemicals consumed and released in the refrigeration process.
