お改良の余地がある。PRIOR ART In this type of pump, a plunger reciprocates through the upper end of the pump cylinder and is formed to provide a discharge passage from the pump chamber to a suitable atomizing button located at the outer end of the plunger. be done. It also communicates around the plunger and the top of the pump cylinder as a means to prevent the liquid in the container from leaking if it is turned upside down during transportation or during use, or if it is roughly handled. There is an external seal to prevent leakage and an internal seal to prevent leakage internally through the plunger from the plunger discharge passage. For example, in the reciprocating pump for liquid dispensing disclosed in Japanese Patent Publication No. 48-44402, the outer seal is sealed and secured by a cylinder and a glasher, respectively, and the outer seal is designed to perform relative axial movement to release the engagement. The internal seal is formed by a sleeve of resilient material within the piston portion and a frictional connection between the lower periphery of the sleeve and the valve of the inlet valve stem. The above method is convenient because the plunger is automatically sealed when the plunger is raised to the fully upright position, but the structure is complicated and the friction connection is disadvantageous. There is still room for improvement, such as the fact that sealing is desired even when the plunger is pressed down and locked.
