<P>PROBLEM TO BE SOLVED: To provide a dispenser container of which the structure does cause troubles due to powder or silicon oil involved in a content in the container, and in addition, for which such a structure can be adopted without requiring a design change of an already existing dispenser container, and without making the structure more complicated. <P>SOLUTION: This dispenser container can discharge the content by a pump mechanism which is fitted in the mouth part of the container and comprises a piston and a cylinder. The piston and parts which operate together with the piston are formed of a thermoplastic polyurethane or an ionomer resin which is equipped with wear-resistance and flexibility, and can elastically absorb powders. Then, the cylinder which relatively operates with the piston and parts integrated with the cylinder are formed of either one of a polybutylene terephthalate, polyamide, polyoxymethylene resin, and a super-high molecular polyolefin resin which is equipped with wear-resistance and hardness. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
