Title:
HIGH-DENSITY LIQUID COSMETIC CONTAINER
Document Type and Number:
WIPO Patent Application WO/2021/091023
Kind Code:
A1
Abstract:
The present invention relates to a high-density liquid cosmetic container that relieves air pressure applied to a piston such that cosmetic content can always be discharged in a constant amount. Conventional cosmetic containers have an issue of content being excessively discharged due to rapid air pressure caused by pumping. To address this issue, the present invention proposes a high-density liquid cosmetic container comprising: a body having a piston inserted thereinside so as to be movable up and down; and a compression part and a nozzle which are respectively coupled to the upper and lower sides of the body, wherein the compression part is coupled by means of a coupling portion fixed to the upper side of the body, and a buffer part having an inner air hole formed therein so as to relieve air pressure generated by rapid compression of the compression part is coupled between the body and the compression part. Accordingly, the present invention has the effect of always discharging the content in a constant amount, since the buffer part that relieves the air pressure generated by rapid compression of the compression part is coupled such that the movement of the piston is controlled by discharging the air at constant pressure through the inner air hole for as long a time as possible. In addition, since the nozzle is sealed by means of an insertion part and a protrusion part, it is possible to prevent the content from being discharged when storing or carrying the cosmetic container.
