A container adapted to include a pressurized medium therein for purposes of dispensing the contents of the container or alternatively, to function as a heat exchange unit to heat or cool beverage or food contained therein. The container housing the pressurized medium includes an over pressure release mechanism which includes a barrier member disposed adjacent a valve stem which when depressed releases the pressurized medium. The valve including the moveable valve stem is carried by a mounting member at least that portion of which carries the valve is moveable outwardly responsive to the pressurized medium exceeding a predetermined pressure internally of the container. Upon such movement, the valve stem contacts the barrier which is stationary with respect thereto and after such contact, further moves the valve stem to activate the valve and release the pressurized medium contained within the container.
