Abstract
In its broadest aspect, the present invention concerns a unitary flexible barrier of phallic configuration for use in a plural-zoned, valved pressure container wherein the barrier has a shaped spatial form having sufficient rigidity to maintain its shape prior to insertion into and use in a plural-zoned, valved pressure container. The barrier comprises a flexible wall portion, the free terminal end of the flexible wall portion forming a seal and the terminus of the flexible wall portion distal to the seal extending into a central piston region that closes the barrier. The wall portion is steeply frusto-conical in shape.
