WIPO Patent Application WO/2019/124996
Kind Code:
A1
Abstract:
The present invention relates to an opening/closing nozzle of a discharge pump for a cosmetic container and, more particularly, to an opening/closing nozzle of a discharge pump for a cosmetic container, the opening/closing nozzle comprising: a container body (10) for containing cosmetic content, an entrance portion (11) being formed in the upper portion of the container body (10) such that content can be injected through the same; a cylindrical shoulder member (20) coupled to the upper-end shoulder portion of the container body (10), the upper/lower portions of the shoulder member (20) being open; an inner cap (30) which is a cylindrical member inserted through the upper hole of the shoulder member (20), the upper/lower portions of the inner cap (30) being open, and the lower inner peripheral edge of the inner cap (30) being screw-coupled to the entrance portion (11) of the container body (10); a discharge pump (40) inserted into the inner cap (30) and coupled therein; an opening/closing nozzle (50) coupled to the upper end of the discharge pump (40) so as to discharge the cosmetic content by means of a pressing operation; a cover member (60) coupled to the upper side of the shoulder member (20); a piston (70) coupled to the lower inner peripheral edge of the container body (10); and a lower cover (80) covering the lower surface of the container body (10) and the outer peripheral edge thereof, wherein the opening/closing nozzle (50) comprises a cylindrical lower body (51), a "ㄱ"-shaped content transfer tube (52) formed inside the lower body (51) and connected to the discharge pump (40), an opening/closing member (54) installed in the content transfer tube (51) so as to operate by means of cosmetic content discharge pressure, thereby opening/closing a discharge port (53), and an upper body (55) coupled to the upper portion of the lower body (51). The present invention, configured as above, is advantageous in that inflow of air into the nozzle of the cosmetic container can be prevented such that not only degeneration of the content and hardening of the content inside the nozzle, which would otherwise occur if air flows into the nozzle, can be prevented, but the reliability of the product can also be improved.
