    • A liquid soap dispenser having a permanent housing permits simplified insertion and replacement of disposable fluid reservoirs. The housing includes an actuator assembly which is cycled by a lever between first and second positions. The actuator assembly couples to a piston element of a piston pump carried on the reservoir. The piston element includes resiliently deformable fingers which act to secure the piston element to the actuator assembly for sliding movement therewith. If, on insertion of a replacement reservoir, the reservoir is positioned uncoupled from the actuator assembly, on first cycling of the actuator assembly the fingers deform to permit movement of the actuator assembly relative to the piston element and move towards a coupled orientation. In the coupled orientation, the fingers return to an undeformed configuration securing the piston element to the actuator assembly.
    • 具有永久壳体的液体肥皂分配器允许简化的一次性液体储存器的插入和更换。 壳体包括致动器组件,该致动器组件通过杠杆在第一和第二位置之间循环。 致动器组件耦合到承载在储存器上的活塞泵的活塞元件。 活塞元件包括可弹性变形的指状件,其用于将活塞元件固定到致动器组件以与其一起滑动。 如果在插入更换的储存器时将储存器定位成与致动器组件脱离联接,则在致动器组件的第一次循环时,指状物变形以允许致动器组件相对于活塞元件移动并且朝着联接方向移动。 在联接方向上,手指返回到将活塞元件固定到致动器组件的未变形构型。
