Vapor tap valve for aerosol containers used with inflammable propellants, and container provided therewith.

摘要

A vapor tap valve for aerosol containers is provided, for use with flammable propellants, inhibiting delivery of flammable liquid propellant when the valve is opened immediately after shaking the aerosol container. The vapor tap valve comprises a movable delivery valve including a valve stem (11), a delivery port (14), and a valve chamber (5); means (spring 18) biasing the delivery valve towards a closed position; a liquid tap orifice (5a) and a vapor tap orifice (2) in flow communication with the valve chamber (5); and a shut-off valve (8b) linked to the delivery valve, closing off the vapor tap orifice (2) against entry of liquefied propellant therethrough into the valve chamber (5), when the delivery valve is closed, and opening the vapor tap orifice (2) when the delivery valve is manually moved to the open position, against the biasing force of the bias means (spring 18).
