Title:
COSMETIC CONTAINER HAVING REPLACEABLE INNER CONTAINER
Document Type and Number:
WIPO Patent Application WO/2021/031798
Kind Code:
A1
Abstract:
Disclosed is a cosmetic container having a replaceable inner container. Two symmetric tabs are disposed at an upper opening of the inner container, and the two tabs are each provided with a tab engagement portion. Accommodation regions recessed inward in a radial direction are symmetrically formed on an external thread of an outer container and shaped as a gap, and an outer container engagement portion is formed at the accommodation regions. The tab engagement portion is engageable with the outer container engagement portion when the tab is bent downward so as to position and connect the inner container to an interior of the outer container. The outer container engagement portion may use various forms, such as a combination of a protrusion fastener and a through hole, a protruding and recessed step difference structure, and the like. The cosmetic container enables, after a substance in the original inner container is finished, a connection between the tab engagement portion and the outer container engagement portion to be released and the empty inner container to be removed, and then enables placement and fastening of a replacement inner container into the outer container. In addition, replacement of the inner container during such process is achievable by a single hand without contacting the opening of an inner container or contaminating a substance therein. The invention provides structural simplicity, facilitates replacement, and enables reuse of the outer container, thereby saving money and achieving environmental friendliness.
