ABSTRACT:
This disclosure pertains to a carbonated beverage container closure apparatus adapted to be removably secured to the container's mouth. A valve is biased to close an opening in the closure having the closing biased forces reinforced by the pressurized gas within the container. A pump apparatus is threadingly engaged on the closure device and is adapted with a check valve such that manual operation of the pump causes the valve in the closure device to open whilst the check valve is closed and air, under pressure, is injected into the container. The pump apparatus may be removed from the container closure device, enabling the container to be stored in a substantially non-heightened profile and enabling the pump apparatus to re-pressurize other containers equipped with similar closure devices.
