Claims

[Scope of utility model registration request]

The spray pump is assembled to the neck of a bottle, and includes a main body tube into which a tip of a suction pipe whose proximal end is open is tightly fitted into the bottom of the bottle, and a first check valve disposed inside; Communication is provided at the tip of the main body cylinder,
A pressure chamber is formed between a nozzle cylinder having a spinner groove and a nozzle hole at its tip and a second check valve disposed inside, and an outer cylinder wall and an inner cylinder wall, and a pressure chamber is formed between the inner cylinder wall and the nozzle cylinder. It has a double-walled structure that communicates with the inside of the bottle, and includes a cylinder tube that protrudes from the outer periphery of the main body tube, a fitting tube portion that is tightly and slidably inserted into the pressure chamber, and a fitting tube portion that is loosely inserted into the inner tube wall. a double-cylindrical piston cylinder including a holding cylinder part that is open at both ends; an elastic spring that is housed in the inner cylinder wall and comes into elastic contact with the piston body; a holding pin that is inserted into the holding cylinder portion and closes the holding cylinder portion at the maximum protrusion position of the piston body due to the elasticity of the elastic spring; a spray pump having an abutting operating lever, and communicating the pressure chamber with a space formed inside the first and second check valves.
