Document Type and Number:
WIPO Patent Application WO/2017/002334
Kind Code:
A1
Abstract:
[Problem] To provide a trigger sprayer offering excellent flow efficiency of liquid in a valve. [Solution] The present invention is a trigger sprayer which is mounted onto a container and with which, in this state, rotation of a trigger part causes a piston part 5 to move and causes pressure to be applied to a liquid inside a cylinder part 42A of a cylinder structure 4, the liquid in the container then being passed through a channel and ejected from a nozzle part 3. The trigger sprayer is provided with: an F-valve 2 provided to a channel between the cylinder part 42A and the container; and an S-valve 1 provided to a channel part between the cylinder part 42A and the nozzle part 3. The S-valve 1 comprises a first valve element 11 and a first valve seat 12; the first valve element 11 is suppressed relative to the first valve seat 12; and when the first valve element 11 opens by moving as being drawn away from the first valve seat 12, the direction of movement of the first valve element 11 and the direction of flow of the liquid are the same.
