Beverage chilling and insulating device

A beverage chilling and insulating device for lowering the temperature of a beverage container and maintaining said lowered temperature, comprising:

• a) an insulated sleeve having a top end and opposite bottom end, the top end open for accepting a beverage container;
• b) a sleeveway defined by said insulated sleeve, said sleeveway sized to accept the beverage container;
• c) an insulated hollow base secured to the bottom end of the insulated sleeve;
• d) a chilling chamber defined by the insulated hollow base, said chilling chamber in communication with the sleeveway;
• e) a cartridge receptacle hole located upon the insulated hollow base, said cartridge receptacle hole extending inward into the insulated hollow base to form a cylindrical cartridge chamber, the cartridge chamber having a series of threads disposed upon the inner surface thereof;
• f) a pressurized refrigerant cartridge which contains a highly pressurized volume of refrigerant, said cartridge cylindrical and elongated in shape and having threads disposed upon an end thereof, said threads corresponding to the threads of the cartridge chamber so that said pressurized refrigerant cartridge may be securely engaged within the cartridge chamber;
• and
• g) a needle valve located in the cartridge chamber opposite the cartridge receptacle hole, said needle valve extending from the cartridge chamber into the chilling chamber, whereby a beverage container is inserted into the sleeveway, and upon engagement of the pressurized refrigerant cartridge into the cartridge chamber, the needle valve punctures the pressurized refrigerant cartridge, allowing the pressurized refrigerant contained therein to escape from the pressurized refrigerant cartridge through the needle valve and into the chilling chamber and sleeveway which is in communication therewith, the refrigerant then lowering the temperature of the beverage container, the beverage container maintained at this decreased temperature for an extended period of time by the insulative properties of the insulated wall.
