Abstract

A hand operated pump dispenser adapted to be fitted to a fluid container to dispense the fluid as a spray has a discharge reservoir in the form of a bellows 11 having an inlet closed by a one way valve 13 allowing fluid into the bellows and a finger operated discharge valve 31, the bellows being charged and discharged by movement of the inlet relative to the housing, the charging movement of the bellows inlet also energising an energy storage spring 38 and being effected either by rotation of, as shown, or downward pressure on, Fig. 4 (not shown), a first actuating member. <IMAGE>
