ABSTRACT:
A container and closure assembly for storing fluids under pressure has cooperating screw threads on the neck of the container and the closure. Mutually engageable elements on the neck and closure block the rotation of the closure in the unscrewing direction beyond an intermediate position when the closure is under pressure. The neck of the container and the closure are constructed to provide a vent for releasing this pressure to allow the closure to be fully removed.
