Title:
AIRTIGHT POWDER DISPERSING CONTAINER
Document Type and Number:
WIPO Patent Application WO/2023/213144
Kind Code:
A1
Abstract:
An airtight powder dispersing container, comprising an outer cover (10), an inner cover (20), an inner screen (30) and a base (40). The inner screen (30) is hermetically mounted at an open end of the base (40), the inner screen (30) is located between the inner cover (20) and the base (40). The inner cover (20) is hinged to the inner screen (30) by means of a hinge unit, and the hinge unit is elastic, so that the inner cover (20) can move towards the side of the inner screen (30) when under stress; and when the outer cover (10) covers the base (40), the outer cover (10) extrudes the inner cover (20) to enable the inner cover (20) to be tightly attached to the inner screen (30). The inner cover (20) and the inner screen (30) are hinged to each other, and the inner cover (20) and the inner screen (30) can be tightly fitted together under the extrusion force of the outer cover (10), thereby ensuring the air tightness of the inner screen (30), and effectively preventing a volatile solvent in a cosmetic material in the base (40) from volatilizing.
