Abstract

The present invention relates to a dispenser, particularly a dispenser for liquid soap and more particularly to such dispensers having disposable refill packs. The invention provides a particularly simple dispensing mechanism (1) comprising a pump chamber (2) the volume of which may be varied. The pump chamber having a non-return valve (10), permits liquid to enter the chamber from a liquid reservoir (8). A non-return outlet valve (14) at its lower end permits liquid to exit the chamber when the pressure in chamber (2) is increased. The outlet valve (14) comprises a single insert (15) designed to cooperate with the profiled inner wall of the outlet nozzle (4) of the dispenser mechanism, to provide a reliable non return valve function, to dispense liquid soap at a steady stream and to prevent drips after completion of a dispensing cycle.
