ABSTRACT:
The aerosol valve of this invention in its novel aspects comprises a valve stem having an enlarged body portion beneath the valve stem, the body portion having a tubular portion extending from its base and a valve housing having an upstanding tubular portion with a sloped upper portion terminating in a shoulder, which sloped upper portion and sloped shoulder are designed to receive the tubular portion extending from the base of the body portion in a sealed relationship when the valve stem is manually advanced to an open position. Conventional aerosol valve components such as the encircling gasket for sealing the valve stem orifice(s), a spring for returning the valve stem/body to a closed position upon release of manual pressure to the valve stem, a dip tube extending downwardly from a nipple at the base of the housing and a mounting cup for affixing the valve unit to the cup and ultimately to an aerosol container also form parts of the aerosol valve of this invention.
