Abstract:

A vacuum pump for removing air from containers includes a pump housing in the form of a conduit with an open end and a closed end. A piston in the form of a conduit, open at each end, is slidably mounted within the housing, and has an inside end within the housing and an outside end protruding from the housing. The outside end of the piston is adapted to fit over a valve secured to the container. A piston ring is provided substantially at the inside end of the piston. The piston ring is adapted to mate tightly with an interior surface of the housing, such that movement of the housing away from the outside end of the piston will draw a vacuum through the valve to remove air from the container through the valve. A system and method for removing air from containers is also disclosed.
