ABSTRACT:
A dispensing device for a pressurized liquid container capable of delivering metered quantities of an aerosol composition having a discharge tube through which the container can be filled with fluids under pressure including a generally cylindrical chamber including an upper chamber and a generally cylindrical lower chamber, a discharge tube mounted in the sealed upper end of the chamber and extending into the chamber, the discharge tube being axially movable in the chamber and having a cup-shaped piston member rigidly connected thereto, the cup-shaped piston having a resilient rim slidable within the lower chamber when the discharge tube is depressed a predetermined amount to isolate a metered quantity of fluid within the upper chamber, the rim of the cup-shaped piston member being sufficiently resilient to allow fluids introduced under pressure through said discharge tube during filling of the container to flow between the rim and the side walls of the lower chamber.
