Abstract:
In an aerosol valve comprising a hollow valve stem having a valve body at the base of the valve stem and a gasketed valve stem orifice, a valve housing surrounding the gasketed portion of the valve stem and the valve body, wherein said valve stem moves reciprocally within said valve housing in response to the presence or absence of manual force against the valve stem and, further, wherein there is a conduit for the flow of product/propellant from an associated pressurized aerosol container to the interior of the valve housing, the improvement comprising the base of the valve body having a tubular extension depending therefrom and the base of the valve housing having an upstanding tubular portion, which tubular extension may advance and abut against a surface of the upstanding tubular portion to form a seal between the tubular extension and the upstanding tubular portion to thereby preclude flow of product/propellant to the valve stem orifice when the valve is in an open position.
