The inner ring member 01 includes an inner lower wall 3, an inner upper wall 1, an inner side wall 2, which form a coupling notch K into which the outer edge of the cover 001 is snapped. Preferably, the inner lower wall 3 and the inner upper wall 1 respectively fit the upper and lower surfaces of the lid body 001, and the outer edge of the lid body 001 and the inner annular member 01 are adhered by an adhesive.

The outer annular member 02 comprises a first annular wall 4 covering the upper end surface of the box 100, a second annular wall 5 closely contacting with the inner wall of the box 100 and a third annular wall 6 pressing against the inner wall of the box 100, wherein the outer end of the third annular wall 6 exceeds the second annular wall 5 and the outer end of the third annular wall 6 does not exceed the outer end of the first annular wall 4.

Preferably, as shown in fig. 3, the cover is circular, square or oval in shape to fit the opening of the case 100. The material of the cover 001 is glass, plastic or metal. The sealing member 002 is an elastic silicone rubber or rubber member.

Specifically, as shown in fig. 1 to 6, the first annular wall 4 extends substantially in the horizontal direction, and positions the body of the cap 200 at the upper end of the mouth of the case 100 in the axial direction, so that the cap 200 does not slip downward, and a first seal is performed between the cap 200 and the case 100.

The extending direction of the second annular wall 5 is the same as the extending direction of the inner wall of the box body 100, and the outer diameter is adapted to the inner diameter of the opening of the box body 100, so that the second annular wall 5 can smoothly enter the opening of the box body 100 and tightly contact the inner wall surface of the box body 100, thereby forming a second seal between the sealing box cover 200 and the box body 100.

The third annular wall 6 forms a certain angle with the second annular wall 5 under the state that the third annular wall is not extruded on the inner wall of the box 100, and the outer diameter of the third annular wall is larger than the inner diameter of the opening part of the box 100; when the third annular wall 6 enters the opening of the box body 100, it is pressed by the inner wall of the box body 100 and then elastically deformed to form an interference fit with the inner wall of the box body 100, thereby providing an outward tension to the inner wall of the box body 100 and forming a third seal between the box cover 200 and the box body 100.
