Abstract

See full text

A liquid soap dispenser is disclosed having a permanent housing which permits simplified insertion and replacement of disposable fluid reservoirs. The housing includes and actuator assembly which is cycled by a lever between first and second positions. The actuator assembly is configured to couple to a valve assembly on the reservoir so that when cycled, the valve assembly is actuated in sliding movement to dispense a quantity of fluid. The actuator assembly includes a pair of resiliently deformable fingers which act to secure the valve assembly 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 valve assembly and move towards a coupled orientation. In the coupled orientation, the fingers return to an undeformed configuration securing the valve assembly to the actuator assembly.
