摘要：In a valve assembly for a pressurized fluid dispensing container, such as thosecommonly known as aerosol cans, the filling with propellant gas at the very high speedand pressure needed to meet current production rates presents problems. The inventioninvolves crimping the center boss of the sheet metal mounting cup in such a way, and at apoint below the enlarged head portion of the valve housing, that the part of the bossabove the crimp and around the valve housing bows outwards to provide clearance for\"gassing\". There are notches in the lower part of the outside of the head portion butthese stop short of the upper face of the head. The valve stem may also have externalaxial grooves placed to increase the effective cross-sectional area during gassing.
