<p>The present invention relates to a pump container cap of automatic opening/closing dispensing type which is connected to a container body (110) for storing cosmetics, and comprises: a cylindrical support cap (120) which constitutes a cylindrical member screw-coupled to the container body (110), and which is formed so as to have an expansion section (121) expanding to the outer circumferential surface on the upper part of the cylindrical shape, and is formed so as to have a support plate (122) protruding horizontally on one side of the expansion section (121); a pressing member (130) of a silicone rubber having a resilient restoring force provided with an outer circumferential groove (131) for inserting in a columnar protrusion (123) protruding from the inner circumferential edge of the upper screw part of the cylindrical support cap (120), whereby a cosmetic is discharged by pressing the upper surface thereof and the cosmetic is sucked inside the container body (110) and so accommodated therein by releasing the pressed state; a cover member (140) for covering an upper outer circumferential edge of the pressing member (130); and a cylindrical connecting member (170) constituting a cylindrical member having upper and lower openings, which is provided with a top-side outer circumferential protrusion (171) that is inserted into an inner peripheral groove (132) on the lower inner circumferential edge of the pressing member (130) inserted into the cylindrical support cap (120), wherein a disk shaped valve (150) is seated by being inserted through the upper opening thereof, and wherein a hose (160) for sucking cosmetics is inserted through the lower opening thereof. The present invention, which is configured in this way, provides the advantage of being able to not only stop hardening of cosmetics but also to prevent deterioration of cosmetics because the pressing member of a flexible material having a resilient restoring force such as a silicone rubber operates in pumping fashion, thereby opening a cosmetic discharge port and at the same time discharging the cosmetic due to the expansion pressure, and, when the pressing is released, the discharge port is automatically closed, thereby preventing contact between the cosmetic and the outer air. Furthermore, the present invention provides the advantages not only of easy assembly and reduced manufacturing cost by simplifying components of the pump container cap of automatic opening/closing dispensing type, but also that deterioration of the cosmetic is stopped since no use is made of components such as a metal spring.</p> |
