The present invention is a manual spray pump which by pressing a button sprays a certain quantity of matter and thereafter sucks in the residual matter in the tip of the nozzle. The manual spray pump comprises: a housing which configures external appearance; a housing cap which seals the inside of the housing; a closure by which a housing can be mounted at a container including matters, and which is integrated with the housing cap; a stem which moves up and down in the state of being connected to the bottom of the button; a shaft which moves up and down along the inner surface of the housing cap in the state of being combined with the outer surface of the stem; a piston which moves up and down along the inner surface of the housing; a compressive spring which is placed between a lateral projection formed on an upper lateral portion of the shaft and the housing cap; an opening and closing member which moves up and down along a perpendicular passage through the bottom of the stem to suck in the residual matter in the nozzle after pumping; and a sealing member which is installed on the bottom of the stem in the state of being fixed to the outer surface of the control member, which is inserted into the perpendicular passage. |
