Abstract
A valve for a pressurized dispenser which includes, within a mounting cup, a valve housing and an annular gasket clamped between the cup and the housing for sealing a discharge passage of a movable valve stem, and which incorporates a clearance space in the cup around the outer marginal portion of the gasket to accommodate the marginal portion when the gasket is stretched during the filling of the dispenser to provide a flow path to the outside of the housing, and which has spacers spaced apart around the periphery of the gasket to define the distance between the cup and the housing within which the gasket is clamped, and between which the stretched gasket extends.
