摘要：A valve for a pressurized dispensing container comprises a valve housing (11)defining a valve chamber (15) and having at its lower end an inlet for pressurized material.An annular flexible seal (12) closes the upper end of the chamber, there is a cup-shapedvalve member (13) within the chamber, and a hollow actuator stem (16) extends in sliding,sealed relation through the seal (12) and engages the valve member (13) at its lower end.A spring (14) urges the valve member (13) upwardly into sealing engagement with theseal (12), the actuator stem (16) being manually moveable downwardly against the actionof the spring (14) to unseal the valve member (13) and open the valve. The wall of theactuator stem (16) includes at least one radial, aperture (24) adjacent to but spaced fromthe lower end of the actuator stem and defining a lip portion (25) adjacent the lower endof the actuator. The aperture or apertures (24) place the interior of the actuator stem(16) in communication with the interior of the valve member (13) and the lip portion (25)serves to restrain the lower end of actuator stem (16) from passing through the seal (12)if the actuator stem is moved upwardly of the seal.
