Abstract
A vapor tap valve for aerosol containers is provided, for use with aerosol compositions containing liquefied flammable propellants, inhibiting delivery of flammable liquid propellant when the valve is opened immediately after shaking the aerosol container and contents, comprising, in combination, a delivery valve movable manually between open and closed positions and including a valve stem, a delivery port, and a valve chamber; a bias spring in the valve chamber biasing the delivery valve towards a closed position; a liquid tap orifice in flow communication with the valve chamber; a vapor tap orifice in flow communication with the valve chamber; and a shut-off valve linked to and movable with the delivery valve, closing off the vapor tap orifice against entry of liquefied propellant therethrough into the valve chamber when the delivery valve is closed, and opening the vapor tap orifice when the delivery valve is manually moved to the open position, against the biasing force of the bias spring.
