Trigger sprayer

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 partis 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 partA of a cylinder structural partso that the liquid in the container is jetted from a nozzle partthrough a passage P. An F valveattached to a bottom part of the cylinder partA serving a passage between the cylinder partA and the container and an S valveinstalled in a passage part P between the cylinder partA and the nozzle partare installed, and the F valveis constituted by a cylinder-shaped base partand a second valve bodyhaving a sealing function as well as a small springA coupling the cylinder-shaped base partand the second valve bodyto each other, and the second valve bodyis further provided with a lower face part and a tilt partA on an opposite side, and the lower face part is fitted into the bottom part of the cylinder partA to be fixed therein, with the second valve bodybeing resiliently made in contact with a second valve mountAformed on the bottom part of the cylinder partA, and by pushing the tilt partA of the second valve bodyby the bottom part of the piston part, the second valve bodyis tilted so that one portion thereof is separated from the second valve mountA, thereby opening the valve.
