PROBLEM TO BE SOLVED: To provide a trigger dispenser with such advantages that it can be compactly constituted with a significant degree of freedom in the dimensional change of a pump chamber, or the like, and a required urging force can be obtained by using a synthetic resin spring which needs not be disposed of by sorting, and further, no difficulty occurs in the case of a switching operation following the constitution of a rotary slide valve in a compact form. SOLUTION: This trigger dispenser 50 for discharging a fixed amount of a charged liquid each time by vertically sliding a piston 107 in the pump chamber 109 through the rocking operation of a trigger lever 51 is of such a construction that an urging force for returning the trigger lever 51 and the piston 107 to their original positions is imparted with the synthetic resin spring engaged with a dispenser body part outside the pump chamber 109 and the back face of the trigger lever 51. Thus, it is possible to constitute the trigger dispenser 50 in a compact form and provide a significant degree of freedom in the dimensional change of the pump chamber 109, and further, obtain the required urging force while eliminating the necessity to perform the sorting/ disposal operation of the spring. In addition, it is also possible to ensure the secure operation of the trigger dispenser 50, even when a fingering part 65 is formed at least at a part of the outside of a rotary slide valve 61 to realize the constitution of the trigger dispenser 50 in a compact form. |
