Abstract:
To provide a trigger sprayer that can maintain uniformity of a chemical solution containing fine powder and is superior in flow efficiency. The trigger sprayer of the present invention is designed such that a piston part  5  is moved by a pivotal movement of a trigger part, while being attached to a container, so as to apply a pressure to a liquid inside a cylinder part  42 A of a cylinder structural part  4  so that the liquid in the container is jetted from a nozzle part  3  through a passage P. An F valve  2  attached to a bottom part of the cylinder part  42 A serving a passage between the cylinder part  42 A and the container and an S valve  1  installed in a passage part P between the cylinder part  42 A and the nozzle part  3  are installed, and the F valve  2  is constituted by a cylinder-shaped base part  22  and a second valve body  21  having a sealing function as well as a small spring  22 A coupling the cylinder-shaped base part  22  and the second valve body  21  to each other, and the second valve body  21  is further provided with a lower face part and a tilt part  21 A on an opposite side, and the lower face part is fitted into the bottom part of the cylinder part  42 A to be fixed therein, with the second valve body  21  being resiliently made in contact with a second valve mount  42 A 1  formed on the bottom part of the cylinder part  42 A, and by pushing the tilt part  21 A of the second valve body  21  by the bottom part of the piston part  5 , the second valve body  21  is tilted so that one portion thereof is separated from the second valve mount  42 A 1 , thereby opening the valve.

Claim (Index 2):
The trigger sprayer according to  claim 1 , wherein the bottom part of the piston part is made in contact with the tilt part of the second valve body and further moved so that a liquid located between the piston part and the cylinder part is returned into the container.
