ABSTRACT:
In an aerosol valve comprising a mounting cup, a gasket having a central opening, a valve housing, a valve stem and a valve body, where the valve stem and valve body move within the valve housing in response to pressure on the valve stem, the valve body has at least one upstanding wall defining a recess. A slot extending from the top shoulder of the upstanding wall communicates with the interior of the container when the valve is actuated. The valve stem has an orifice aligned with the longitudinal opening of the valve stem which communicates at one end with the slot in the recess of the valve body and at the other end with the orifice in the valve stem. The central opening of the gasket seals the slot defined by the upstanding wall of the valve body when the valve is in a closed position. The valve body also has a shoulder with an annular recess at the base of the upstanding wall.
