Contents Dispensing Pump
(57) Abstract
The present invention relates to a contents dispensing pump which is coupled to a container (V) for accommodating the contents therein and dispenses the contents, comprising: a pump main body ( 10 ); a pump upper body ( 20 ); a pump inner body ( 30 ); a dispensing valve ( 40 ); and an elastic member ( 50 ). The pump upper body ( 20 ) is coupled to the upper side of the pump main body ( 10 ) so that a pumping operation is made by an up and down movement with respect to the pump main body ( 10 ). The pump inner body ( 30 ) has a bowl shape with the middle thereof formed to be dented so that an inlet valve plate ( 70 ) is integrally formed on the lower surface. The dispensing valve ( 40 ) is coupled to the upward side of the pump upper body ( 20 ), and has, formed therein, a valve protrusion wheel ( 41 ) for opening and closing the content outlet ( 23 ). The elastic member ( 50 ) is positioned between the upper lateral surface extension piece ( 33 ) and the lower lateral surface extension piece ( 34 ) of the pump inner body ( 30 ) so as to draw the pump inner body ( 30 ) and simultaneously elastically support the pump main body ( 10 ) and the pump upper body ( 20 ).
