    • A dispenser for a foamable composition comprising a pressurised container containing the foamable composition and having a valve (12), with an actuator (20) mounted on the container. The actuator comprises a flow conduit (31) 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 (40) 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.
    • 一种用于可发泡组合物的分配器,其包含含有可发泡组合物的加压容器并具有阀(12),其中安装有容器上的致动器(20)。 致动器包括与阀杆配合的流动管道(31),并且当向致动器施加致动力时可移动的流动管道(31)承载在阀杆上以致动阀杆,封闭件(40)邻近分配 打开管道。 在没有致动力的情况下,导管偏压闭合。 在向流动管道施加致动力时,流动管道被移位以致动阀杆并且被移出与封闭件的闭合关系。 致动器可以减少组合物的后发泡。
