Abstract
A swabable valve having a collapsible valve stem with a concave curvilinear upper surface extending from rim-to-rim of the valve stem, the concave curvilinear upper surface comprising a radius that is sufficient to prevent the collapsed valve stem from becoming lodged within the valve body upon collapsing thereby assuring that the collapsed valve stem will return to its closed position with the concave curvilinear upper surface substantially flush with the end of the valve.
