Abstract: A trigger-type sprayer with excellent usability is provided capable of locking rotation of a nozzle part without using a separate component so as not to cause a nozzle orifice to be inadvertently opened. A trigger-type sprayer A of the present invention moves a piston part 3 by pulling and rotating a trigger part to compress liquid in a cylinder part and cause the liquid to be injected from a nozzle part 1 communicating with the cylinder part, and the trigger-type sprayer A includes a lock function of preventing rotation of the nozzle part between the nozzle part 1 and the trigger part 5.

Abstract: A pump dispenser includes a housing, a piston structure, a spring, a trigger and a valve. The housing has a front cylinder part and a rear inverted-L-shaped grip part that are integrally formed, a nozzle base that is attached to the housing and that has a front nozzle part mounted thereon. The piston structure is configured of a hollow-shaped piston and a hollow-shaped piston shaft and that slides inside the cylinder part. The spring presses the piston structure upward. The trigger is positioned above the housing, has a front tip rotatably mounted on the housing, and has a mid part where a tip of the hollow-shaped piston shaft abuts. The valve rod is disposed at a center part of the cylinder part.
