摘要:
A wall mounted soap dispenser made of plastic is described. The dispenser includes a hand-operated pump which dispenses liquid soap under pressure and which can be manufactured inexpensively. A disposable container of liquid soap is inserted in the dispenser to refill the dispenser. The pump has on its top a pan to collect liquid spilled as the disposable container is inserted. The pump and container are enclosed in a plastic housing which hinges from a plastic wall plate. A plastic latch with plastic key is used to lock the housing to the wall mounting plate. The pump mechanism uses a piston of two sections of different diameter and corresponding piston chamber of two sections of different diameter. There is an adjustable piston stroke length limiting mechanism. The piston is attached to the lever which moves the piston by means of a crossbar on the end of the piston rod. The crossbar is inserted in a slot in the lever and then turned to cross the slot.
