ABSTRACT:
A cylinder in which a liquid pressurizing chamber is formed is inserted into a liquid container. The cylinder has an unitary large-diameter portion and a small-diameter portion. A first piston is slidably received by the large-diameter portion of the cylinder. The cylinder also slidably receives an operation body including a second piston slidably in the large-diameter portion and a third piston slidably in the small-diameter portion. The liquid in the pressurizing chamber defined by the cylinder and the pistons is pressurized as the operation body is depressed overcoming a force of a spring. A stop valve mounted on the second piston is opened in response to the pressure generated in the pressurizing chamber, so that the liquid is allowed to reach, through a passage formed in the first piston, a nozzle for atomizing the liquid.
