Embodiment Construction

[0013] Such as Figure 1-2 As shown, a kind of makeup case sealing structure described in the present invention comprises box body 1 and box cover 2, adopts screw thread 5 to connect between box body 1 and box cover 2, is provided with box body on the lower edge of box cover 2 1 contact sealing sealing strip 3, the sealing strip 3 is a narrow strip formed integrally with the lid 2 and narrower than the section of the lid 2, the bottom of the narrow strip can be smooth or arc-shaped to achieve good In order to improve the sealing effect, a circle of sealing strip 4 which contacts and seals with the box body 1 is arranged on the inner top of the box cover 2. After the box cover 2 and the box body 1 are tightened, the sealing strip 4 contacts with the box body to achieve the sealing effect.

[0014] This device avoids the problem of poor sealing effect on one side of the thread by simply using the thread seal, because the sealing strip 3 on the lower edge of the box cover 2 and t...

Abstract

A cosmetic container sealing structure comprises a container and a container cover, wherein the container is in screwed connection with the container cover; a sealing strip in contact seal with the container at the low edge of the container cover, wherein the sealing strip is molded in one piece with the container cover with the cross section narrower than the container cover and the bottom of the sealing strip is smooth or arc and one ring of sealing strip in contact seal with the container is set on top of the inner part of the container cover. The cosmetic container sealing structure solves the problem that the sealing effect is bad if only using screw sealing, screw single-side sealing. The sealing strip at the low edge of the container cover and the sealing strip on the top of the inner part of the container cover have double sealing effect. The sealing strip is of elastic deformation without larger effect on opening cosmetic container. During tightening the container cover, the air between the container cover and container is extruded and the negative pressure is formed in the sealing space, favorable for ensuring better sealing effect.

Description

technical field [0001] The invention relates to a cosmetic box, in particular to a sealing structure for a lid of a cosmetic box. Background technique [0002] Commonly used cosmetic boxes and similar containers are sealed with threads, but due to the characteristics of threaded connections, the threads can only be occluded under force on one side, which creates a gap between the other unstressed side, so in fact The sealing effect of the screw thread is limited, and complete isolation from the outside air cannot be achieved. From a practical point of view, it will have an impact on the shelf life of the cosmetics in the box. Adopting such a structure will generally shorten the shelf life of the cosmetics by two to three months. [0003] Some box bodies and box covers are connected by threads, and the lower edge of the box cover is directly in contact with the box body to seal. It is therefore very difficult to reopen the sealed box once sealed. Contents of the invention...
