Device for pressurizing an aerated drink contained in an aerated drink container

Abstract

A novel device for pressurizing an aerated drink remaining in an aerated drink container. The device includes: a cap member having an air vent opening to be removably attached to an open end portion of the container; a first nozzle member securely connected to the cap member and having an upper open end formed into a water supply port to be detachably connected to a water supply source and a lower open end, the first nozzle member being provided therein with a first check valve; an expansible and contractible pouch member attached to the lower open end of the first nozzle member for pressurizing the aerated drink contained in the container; a pouring piece of a relatively short tubular configuration removably attached to the cap member; a second nozzle member having a lower open end detachably connected to the pouring piece for communication therewith and an upper open end formed into an air forcing port, the second nozzle member being provided therein with a second check valve; and means for forcing air into the container through the air forcing port of the second nozzle member.
