PROBLEM TO BE SOLVED: To provide a trigger type pressure accumulation spray capable of efficiently performing air vent inside a space between a second valve and a first valve, and discharge of a fluid.SOLUTION: A trigger type pressure accumulation spray 10 comprises: a body 30 having a flow channel inside; a cylinder 11 communicating with the flow channel; an upstream first valve 15 inside the cylinder 11; a trigger 12; a piston 13 moving forward and backward by the trigger 12; a plate spring body 20 for returning the trigger 12; a second valve case 14a of the piston 13; a second valve 14 of the second valve case 14a; a tube 19 whose the other end is positioned inside a container; and a nozzle 16 on the downstream side of the body 30. The trigger type pressure accumulation spray 10 moves the piston 13 by the operation of the trigger 12, applies pressure to a fluid in the cylinder 11, and discharges the fluid from the nozzle 16. A basic flow channel for allowing the fluid or air to pass from the inside of a cylinder space to the nozzle is provided between the piston 13 and the second valve case 14a.SELECTED DRAWING: Figure 2 |
