ABSTRACT:
A closure device for a receptacle is provided with a first generally annular member adapted to be fixed to the receptacle across the opening thereof. A second generally annular member is substantially coaxial with the first annular member and is adapted to be axially moved between an inward closed position and an outer open position. An elastically deformable annular membrane member has one end fixed relative to the first annular member and another end for retaining the second annular member. A fluid passageway in the closure communicates with the container interior when the first annular member is in the open position. Valve means cooperates with valve seat for closing off the passageway when the first annular member is in a closed position.
