PROBLEM TO BE SOLVED: To provide a pump dispenser with a trigger, which has simple constitution, the number of whose components is lessened and which has extremely excellent operability. SOLUTION: This pump dispenser 1 is constituted so that a liquid in a cylinder 4g is jetted from a nozzle part 5 by gripping the trigger 4c to depress a piston 7 integrated with the nozzle part 5. The cylinder 4g is formed integrally inside a cylindrical body part 4a arranged along the axial direction of a vessel and the trigger 4c is formed integrally with the cylindrical body part 4a while interposing a hinge part 4b between them. Since the trigger is formed integrally with the cylindrical body part arranged along the axial direction of the vessel while interposing the hinge part between them, a rotational fulcrum of the trigger can be arranged as backward as possible, and consequently, leverage can be made large. Since the body part and the trigger are at least integrally formed from a synthetic resin, the movement of the rotational fulcrum becomes extremely precise. COPYRIGHT: (C)2005,JPO&NCIPI
