ABSTRACT:
A beverage chilling and insulating device comprising an insulated sleeve for accepting a beverage container such as a beer or soda can. The insulated sleeve is secured at a bottom end to an insulated hollow base which defines a chilling chamber, the chilling chamber in communication with the sleeveway. A cartridge receptacle hole is located upon the insulated hollow base and extends inward into the insulated hollow base to form a cylindrical cartridge chamber. A needle valve protrudes from the cartridge chamber into the chilling chamber. A pressurized refrigerant cartridge which contains a volume of pressurized refrigerant such as freon or liquid nitrogen is inserted into the cartridge chamber until the needle valve punctures the cartridge, allowing the pressurized refrigerant contents to escape from the cartridge, through the needle valve into the chilling chamber and sleeveway. The refrigerant then lowers the temperature of the beverage container which is encapsulated within the sleeveway, the beverage container maintained at this decreased temperature for an extended period of time by the insulative properties of the insulated wall.
