Abstract

A pump unit (10) that pumps out a liquid in a container body (12) has a liquid-receiving portion and a piston portion movably inserted in the liquid-receiving portion. The piston portion has a shaft case (20) provided in the liquid-receiving portion and having a female screw portion (20a) formed on its inner periphery, and a piston head portion (21, 22) movably inserted in the shaft case. The piston head portion projects outside the liquid-receiving portion, a discharge opening (22c) is formed at the projecting portion, and a male screw portion (21a) screwed in the female screw portion (20a) is formed on the outer periphery of the piston head portion. A non-screw portion (20b) that allows the male screw portion of the piston head portion to freely rotate in a circumferential direction of the shaft case is formed on the shaft case. In this pump unit, the discharge opening of the piston head portion can be freely rotated separately from movement in discharge operation of the liquid in the container body.
