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 having an inlet closed by a one way valve allowing fluid into the bellows and a finger operated discharge valve, the bellows being charged and discharged by movement of the inlet relative to the housing, the charging movement of the bellows inlet also energizing an energy storage spring and being effected either by rotation or downward pressure on a first actuating member.
