PROBLEM TO BE SOLVED: To provide a trigger type liquid sprayer capable of discharging liquid with small operating force.SOLUTION: There is provided a trigger type liquid sprayer having, in a flow passage P of a sprayer body, a valve member 61 which regulates the flow of liquid in the flow passage P accompanied by the actuation of a pump to the direction from a container side to a nozzle side. The valve member 61 includes: an intake side check valve 63 which allows the liquid to flow toward a pump side from the container side, and also prevents the liquid from flowing toward the container side from the pump side; and a discharge side check valve 64 which allows the liquid to flow toward the nozzle side from the pump side, and also prevents the liquid from flowing toward the pump side from the nozzle side. The discharge side check valve 64 is formed into an elastically deformable umbrella shape in a radial direction, and it is configured in such a manner that it contacts an inner peripheral surface of the flow passage P at its outer peripheral end, and contact force on the inner peripheral surface of the flow passage P at the outer peripheral end is non-uniform in a circumferential direction. |
