A dispenser for a foamable composition comprising a pressurized container containing the foamable composition and having a valve with an actuator mounted on the container. The actuator comprises a flow conduit mated with the valve stem and which is displaceable upon the application of actuating force to the actuator to bear upon the valve stem to actuate the valve stem with a closure adjacent to the dispensing opening of the conduit. In the absence of actuating force, the conduit is biased closed against the closure. On the application of actuating force to the flow conduit, the flow conduit is displaced to actuate the valve stem and to be displaced out of its closed relationship with the closure. The actuator can reduce post foaming of the composition.
