ABSTRACT:
A discrete, internal self-cooling device installed in a standard beverage can during assembly that operates on the principle of heat loss through vaporization. A refrigerant vessel is provided for holding a cryogenic refrigerant. The vessel includes a refrigerant vessel body made up of cylindrical side walls having upper and lower rims, an upper plug sealing the upper end of the vessel and a lower plug sealing a lower medial portion of the vessel. The upper plug includes a metering orifice extending axially therethrough, and the lower plug includes a hole extending therethrough and aligned with the metering orifice. A piston is received within the vessel between the lower rim and the lower plug, and includes a rod-like piston extension extending through the lower plug hole. The piston extension includes a tip dimensioned to be received in the metering orifice in sealing fashion. An edible sealant is applied to the outer edge of the piston and to the piston extension, and the sealant is freezable to temporarily hold the piston and extension tip in a sealing position in the metering orifice during assembly and filling of the vessel with cryogenic refrigerant.
