Document Type and Number:
WIPO Patent Application WO/2017/079885
Kind Code:
A1
Abstract:
Disclosed is a cosmetic container sealed by magnetic attraction and negative pressure, comprising a case (1), a main body (2), an accommodation bottle (3) and a seal ring (6), wherein the case (1) is fitted with the accommodation bottle (3); one end of the main body (2) is fixed inside the case (1), and the other end thereof can extend into the accommodation bottle (3); a first magnetic member (4) is provided on an end surface of the case (1), and a second magnetic member (5) is provided on an end surface of the accommodation bottle (3), so that the case (1) and the accommodation bottle (3) are attracted to one another by the first magnetic member (4) and the second magnetic member (5); and the seal ring (6) is sheathed outside the accommodation bottle (3), a flexible ring (7) is provided on an outer wall of the seal ring (6), and when the case (1) is fitted with the accommodation bottle (3), an inner wall of the seal ring (6) is fitted to the accommodation bottle (3), and the outer wall of the seal ring (6) is fitted to the inner wall of the case (1). The case (1) and the accommodation bottle (3) are fitted closely together by means of the attraction between the first magnetic member (4) and the second magnetic member (5), thereby improving the airtightness of the accommodation bottle (3). When the case (1) is fitted with the accommodation bottle (3), the flexible ring (7) is pressed laterally by the case (1) such that the clearances between the flexible ring (7), the seal ring (6) and the accommodation bottle (3) are reduced to gradually push the air out and form a negative pressure, thereby making the seal ring (6) be fitted closely.
