<P>PROBLEM TO BE SOLVED: To provide a liquid pump distributor in which a pumping flow passage is closed to the outside with the discharge of a liquid suspended by reducing the amount of the liquid remaining in a discharge guide flow passage. <P>SOLUTION: This liquid pump distributor comprises a cap, a pumping operation part, and a push button. The push button is so formed that a sliding guide groove forms a straightline with the discharge guide flow passage and a vent hole is communicated with the sliding guide groove. The liquid pump distributor further comprises a flow passage opening and closing part so formed as to have a sectional area smaller than that of the discharge guide flow passage and having the discharge guide flow passage, a bar-like opening and closing body part formed in the sliding guide groove, an opening and closing wing part so formed all around the outer surface of the opening and closing body part as to be fitted to the inner peripheral surface of the sliding guide groove, and an opening and closing return spring so fitted to the sliding guide groove as to press the opening and closing wing part toward the discharge guide flow passage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
