CONTENTS DISPENSING PUMP

WIPO Patent Application WO/2015/072732

A1

The present invention relates to a contents dispensing pump used by being mounted in a container so as to dispense, to the exterior, contents accommodated in the container by a fixed quantity through a pumping operation and use the contents and, particularly, to a contents dispensing pump which: increases productivity and lowers the product price due to a simple structure of the contents dispensing pump configured in such a manner that a pump upper body is inserted onto the upper portion of a pump main body, a pump inner body is inserted on the inside of the pump upper body and the pump main body, a valve protrusion wheel of a dispensing valve is coupled to a dispensing protrusion rod of the upper portion of the pump upper body so that the pump upper body is made to move up and down with respect to the pump main body and thus the volume in a contents temporary reservoir of the pump inner body is changed, thereby allowing the contents to be dispensed; and at the same time, can be easily mounted even in a product having a small space in which the dispensing pump is to be mounted, by performing a pumping operation by changing the volume of the temporary contents reservoir due to a deformation of the pump inner body such that a working stroke distance of the dispensing pump can be short as in a compact type gel-phase foundation container. To achieve the purpose, 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 main body (10) has a bowl shape with the middle thereof formed to be dented so that a contents inlet (12) is formed in the center of a main body lower plate (11), an inlet ring-type protrusion (13) being formed on the outer side of the content inlet (12), and a pump inner body projection (14) is formed in the inner lateral side so as to be coupled to the pump inner body (30). 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 upper body (20) has a dented dispensing valve coupling space (22) formed in the center of an upper body upper plate (21), wherein a dispensing protrusion rod (24) having a contents outlet (23) formed therein is formed in the center of the dispensing valve coupling space (22) and a dispensing valve coupling step (25), to which a dispensing valve (40) is coupled, is formed in the side wall surface of the dispensing valve coupling space (22). In addition, in the downward side of the upper body upper plate (21), formed are a first coupling extension piece (28) to which the pump inner body (30) is coupled and a second coupling extension piece (29) laterally separated from the first coupling extension piece at a predetermined interval. 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, a corrugated tube (31) is formed in the lateral lower portion and a pump upper body coupling piece (32), to which the pump upper body (20) is coupled, is formed in the upper portion, an upper lateral surface extension piece (33), which is integrally extended, is formed in the outer side of the upper end of the pump upper body coupling piece (32), and a lower lateral surface extension piece (34), which is integrally extended, is formed in the outer side of the lower end of the corrugated tube (31). The inlet valve plate (70) forming the lower surface of the pump inner body (30) has, formed in the center thereof, a valve plate (71) for covering the contents inlet (12) of the pump main body (10), wherein, in the downside of the outer side of the valve plate (71), a valve plate ring-type protrusion (72) is formed so as to contact the inlet ring-type protrusion (13) of the pump main body (10) in a staggered manner and block distribution of the contents, and an elastic piece (73) is formed so as to integrally connect the outer surface of the valve plate (71) and the inner lower end of the pump inner body (30). The dispensing valve (40) is coupled to the upward side of the pump upper body (20), and has, formed therein, a valve protrusion wheel (42) for opening and closing the content outlet (23) of the pump upper body (20) and a coupling protrusion wheel (42) coupled to the pump upper body (20) and formed laterally to the valve protrusion wheel (41), wherein a space (43) is formed between the valve protrusion wheel (41) and the coupling protrusion wheel (42) so as to enable the valve protrusion wheel (41) to move when turned on or off. 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). A coupling auxiliary member (60) is used as a coupling auxiliary means when coupling the dispensing valve (40) to the pump upper body (20). The coupling auxiliary member (60) is cylindrically formed, has an insertion protrusion (61) formed in the inner surface thereof so as to be coupled to an insertion groove (45) of the dispensing valve (40) and has a pump upper body coupling step (62) formed in the outer surface thereof so as to be coupled to the dispensing valve coupling step (25) of the pump upper body (20).
