- a pump dispenser that discharges liquid and a discharge container using a pump dispenser have been known.
- a pump dispenser When assembled, such a pump dispenser is unitized as part of a piston unit, with the liquid piston, inner rod, plug, and coil spring.
- the parts used in pump dispensers are manufactured by molding resin, and the inner rod, for example, is also made of resin.
- the strength of the parts tends to be compromised, so specifications are required that ensure that no defects occur during manufacture or use, even for parts with a reduced amount of resin.
- the axial centers of the inner rod and plug may become misaligned due to the mechanical clearance between the inner rod and plug of the pump dispenser, and the positioning accuracy of the assembly device in the piston unit. This misalignment causes the inner rod to tilt relative to the axial center of the plug as it is inserted.
- the present invention aims to provide a pump dispenser, a dispensing container, and a dispensing container containing a content that can suppress the relative inclination of the inner rod and the plug during assembly.
