Abstract:
A valve assembly for a closed application system comprising a first valve component, a second valve component mounted to said first valve component, means for rotating said first valve component relative to said second valve component for selectively moving said valve assembly between a closed position and an opened position; a guide element extending from one of the first and second valve components, said guide element comprising means for guiding said valve assembly into retaining means for said valve assembly; and means for removably mounting said valve assembly to a discharge nozzle of a container such that said valve assembly is coupled to said container in substantially sealing relationship for providing a substantially closed flow path between said container and said valve assembly;wherein said first valve component has a top surface defining at least one opening therein, said second valve component has a top surface defining at least one opening therein; said openings in said top surfaces of said first and second valve components being selectively movable into and out of alignment as said first and second valve components are rotated relative to each other for moving said valve assembly between said closed and opened positions;wherein said first and second valve components are arranged in said valve assembly such that at least one said slot is defined proximate to the top of said second valve component when said first and second valve components are rotatable mounted to each other; and stop means operatively associated with said slot to limit relative rotation of said first and second valve components.
