When the outer cover 20 is sleeved on the inner cover 30, the peripheral wall 22 of the outer cover just fits the outer cylinder 31 of the inner cover, and there is a gap between the outer cylinder and the inner cylinder, so the outer cylinder has a certain elasticity, which is convenient for the assembly and disassembly of the outer cover and the inner cover.

[0038] The outer cylinder 31 is a rectangular parallelepiped structure with a hollow interior, the inner cylinder 32 is a cylindrical structure with a hollow interior, a plurality of upwardly protruding bosses 33 are provided on the bottom plate 34, and an outer ring 42 is formed by extending upwardly on the top plate 36 outside the inner ring 37, an inner thread 43 is provided on the inner wall of the lower end of the inner cylinder 32, and a second inclined surface 39 and a second stop surface 41 are provided on the buckle 38. The plurality of bosses 33 are evenly distributed along the central axis of the inner cover 30, the bottom plate 34 is located below the top plate 36, and the bottom plate and the top plate are arranged in a horizontal direction and parallel to each other, and the inner cylinder 32, the second connecting portion 35, the inner ring 37 and the outer ring 42 are arranged in a vertical direction and parallel to each other.

[0039] The elastic clip 12 of the top sheet 10 is inserted into the inner ring 37, and the elastic clip 12 is stopped by the second stop surface 41, the pressing portion 51 of the button 50 is inserted into the gap between the elastic clip 12 and the inner ring 37, and the elastic gasket 60 is installed on the lower surface of the bottom plate 34 and is located below the button 50. During assembly, the boss 25 of the outer cover is placed on the top plate 36 of the inner cover, the boss is against the outer ring 42 of the inner cover, the buckle 38 of the inner cover extends into the receiving groove 23 of the outer cover, the elastic clip 12 slides down along the second inclined surface 39 of the buckle until the first inclined surface 13 slides below the second inclined surface 39, and the first stop surface 14 and the second stop surface 41 are engaged with each other, thereby limiting the inner cover 30 and the outer cover 40 to each other, and the two will not be separated.

[0040] like Fig.12 and Fig.13 As shown, the upper end of the box body 70 is a second joint portion 71, and the inner side wall of the second joint portion 71 is provided with an outer thread 72 that cooperates with the inner thread 43 of the inner tube 32. The inner cover 30 is sleeved on the second joint portion 71 of the box body, and the box body 70 and the inner cover 30 are fixed by screwing with inner and outer threads. Of course, other methods such as snap-fitting can be used for fixed connection. In this embodiment, the box body 70 is a rectangular parallelepiped structure with an open upper end, and the second joint portion 71 is a hollow cylindrical structure. From the outside, only the outer cover 20 and the box body 70 are seen, and the overall cosmetic box is a square structure.

The button 50 is a disc-shaped structure, and the pressing portion 51 is hollow inside. Figure 8As shown, the third inclined surface 52 of the pressing portion forms an angle greater than 90° with the horizontal plane. During installation, the button 50 is placed in the first through hole on the chassis 34 and the pressing portion 51 is inserted into the gap between the elastic clip 12 and the inner ring 37. The third inclined surface 52 is fitted to the first inclined surface 13 on the elastic clip. The first inclined surface and the third inclined surface have the same inclination. The elastic gasket 60 is fitted to the lower surface of the button. By pressing the elastic gasket 60, the button moves upward under the action of the pressing force, and the first inclined surface 13 shrinks and deforms inward under the action of the third inclined surface 52, so that the first stop surface 14 of the elastic clip 12 is separated from the second stop surface 41 of the buckle, that is, the top sheet 10 is separated from the inner cover 30, and then the outer cover 20 and the inner cover 30 are separated, which can be classified and recycled.
