Tennis ball rejuvenator and maintainer

摘要

A pressure vessel for storing tennis balls includes a cylindrical open topped receptacle having in its inside upper border a peripheral groove separably engaging an elastomeric O-ring gasket provided with a finger removal tab. A vertical coaxial post is anchored to the receptacle base and axially movably supports for movement between limited raised and depressed positions a coupling member which is spring urged to raised position and releasably locked in its depressed position. A dished cover is coaxially separably connected to the coupling member and has an outwardly downwardly inclined peripheral lip engaging the O-ring when the cover is in raised position to effect an air tight seal. Mounted on the receptacle peripheral wall and communicating with the interior thereof are a pressure gauge, a pressure release and safety valve and a pressurizing check valve.
