Document Type and Number:
WIPO Patent Application WO/2016/199382
Kind Code:
A1
Abstract:
[Problem] To provide a pump dispenser configured so that the position of the nozzle does not move vertically, thereby enabling the direction of ejection of liquid to be determined appropriately, and so that the trigger can be operated easily. [Solution] This pump dispenser is configured so that a piston section is slid to apply pressure to liquid within a cylinder section provided with an F valve, thereby ejecting the liquid from a nozzle section through an S valve. The pump dispenser has a mounting structure for the F valve, and in the mounting structure, the F valve is mounted within the cylinder section using a valve stopper. The F valve comprises a valve body section and a rod-like section which extends upward from the valve body section. The valve body section has, arranged therearound, a plurality of guide sections and a plurality of retaining sections. The valve stopper has a hole and has a cutout through which the guide sections can pass, the hole and the cutout being formed in the ceiling section of the valve stopper, and the valve stopper can be affixed within the cylinder section. The retaining sections can elastically pass through the hole in the valve stopper when the valve body section of the F valve is inserted through the hole, and after the insertion, the retaining sections of the F valve make contact with the ceiling section of the valve stopper to retain the F valve.
