Patent
CA 2592728
A liquid soap dispenser is disclosed having a permanent housing which 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 is configured to couple to a piston element of a piston pump carried on the reservoir so that when cycled, the piston element is actuated in sliding movement to dispense a quantity of fluid. 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.
