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 6):
The trigger sprayer according to  claim 3 , wherein a suspending-type cylinder part is formed onto an upper end of the column hole of the cylinder structural part so as to be suspended, and with the inner circumference of the suspending-type cylinder part, the diameter expanding part of the first valve body of the S valve is slidably made in contact, and onto the inner circumferential face of the electing cylinder part of the attaching base part, a coil spring for resiliently pressing the first valve body downward is attached.
