Abstract
A self-cooling container incorporating a heat exchange unit including a chamber for containing a quantity of a gas, the chamber including an external wall in contact with the beverage to be cooled, actuator means for actuating the heat exchange unit, a liner member disposed concentric and inside the wall of the chamber for facilitating flow of the gas throughout the heat exchange unit, and a means for exhausting the gas from the chamber. The actuator means includes a valve for controlling the release of the gas from the chamber having a valve stem which when reciprocated axially will open and close the valve to allow gas to discharge through the stem. The actuator means also includes a sealer having a plurality of tabs spaced around its outer periphery for preventing the heat exchange unit from coming out of the container. A support member is affixed to the base of the chamber for locking the heat exchange unit in position after it is inserted in the container. The support member includes a first and second ring connected together by a plurality of arms, wherein the first ring is affixed to the chamber and the second ring is constructed to fit within the countersink of the container.
