A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has a variable volume pump chamber within a component retaining body. The chamber is defined by a bellows having a closed end or bottom, an open end or top, and corrugated sidewalls characterized by their resilience or elastic memory, and fabricated of any of the various thermoplastics. The bellows is associated with a movable member in the form of a trigger which when actuated compressively stresses the bellows in a direction significantly to reduce its length and the volume of the chamber therewithin. When the compression stress applied by the actuating member or trigger is relieved or removed, the bellows regains its original size and shape and returns the actuating member to its initial position. Associated inlet and outlet valves and respective conduits are also incorporated in the device whereby liquid in the liquid container is drawn into the chamber and pumped through a discharge nozzle in the form of a spray, as desired. The alternate application and relief of compressive stress by the trigger or operating member also opens and closes the valves so that liquid can be drawn into the chamber and dispensed therefrom.
