[0034] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0035] like Figures 1-6 As shown, this novel experimental invention provides a double-lid powder box with a rear-clamp interference fit, which includes a box body 100, and a first lid 200 and a second lid 300 respectively rotatably connected to opposite sides of the box body 100.

[0036] The box body 100 of this utility model is rectangular, and it has a first partition and a second partition. The size ratio of the first partition and the second partition can be determined according to actual usage needs. In this experimental model, the area of ​​the first partition is larger than the area of ​​the second partition. The first partition settles to form a first receiving chamber 103 with the opening facing upward. To facilitate the storage of cosmetic powder, an inner box 105 is snapped into the first receiving chamber 103. Each of the opposite side surfaces of the inner box 105 is provided with a wedge-shaped flange 1051 at intervals, and the inclined surface of each wedge-shaped flange 1051 is set downward to snap into the inner box 105. The first receiving chamber 103 has a snap-fit ​​groove 1031 at the position corresponding to the flange 1051. Each flange 1051 snaps into the snap-fit ​​groove 1031, so that the inner box 105 is snapped into the first receiving chamber 103.

[0037] The inner box 105 of this utility model has four storage areas for storing cosmetic powder. The specific number and size of the storage areas can be set according to actual usage needs and there are no special restrictions.

[0038] The second partition settles to form a second accommodating chamber 104 with its opening facing upwards. To facilitate the user's grip on the box 100, an anti-slip slope 1041 is also provided inside the second accommodating chamber 104. The anti-slip slope 1041 is set with a gradually increasing slope from the side of the second accommodating chamber 104 closer to the first partition to the other side farther away from the first partition. Several protrusions 1042 are arranged in a rectangular array on the anti-slip slope 1041.

[0039] On the two sides of the first and second partitions that are far apart, a first cover 200 and a second cover 300 are rotatably connected respectively. The size of the first cover 200 is suitable for the size of the first partition, and it rotatably covers the first partition. The size of the second cover 300 is suitable for the size of the second partition, and it rotatably covers the second partition.

[0040] The bottom middle part of the side of the first cover 200 that is rotatably connected to the first partition extends downward to form a long rectangular first rotating shaft 201. The bottom of the first rotating shaft 201 has an arc surface, and a connecting blind hole 202 is provided on each side of the first rotating shaft 201 along its length direction.

[0041] The first partition, which is rotatably connected to the first cover 200, is recessed inward toward its central axis to form a shaft groove 101. Two rear-fastening protrusions 400 are symmetrically spaced along the side of the shaft groove 101 along its length direction. These two rear-fastening protrusions 400 are located within the rotation path of the first rotating shaft 201, and each rear-fastening protrusion 400 has an interference fit clearance with the first rotating shaft 201. Each rear-fastening protrusion 400 includes a rectangular portion 402 and a rear-fastening inclined surface 401 on the top surface of the rectangular portion 402, the rear-fastening inclined surface 401 facing the first rotating shaft 201.

[0042] To facilitate rotatable connection with the first cover 200, a connecting through hole 102 is provided at each end of the shaft slot 101 along its length. The first rotating shaft 201 is placed in the shaft slot 101, and the rotating connector (not shown) passes through the connecting through hole 102 and the connecting blind hole 202 in sequence, and stops in the connecting blind hole 202. Thus, the first cover 200 is rotatably connected to the box body 100 with the rotating connector on the first rotating shaft 201 as the rotating axis, and the rotation angle is 0-180°. When the first rotating shaft 201 is rotatably connected in the shaft slot 101, the arcuate part of the first rotating shaft 201 abuts against the junction of the rectangular part 402 and the rear buckle slope 401, so that there is an interference fit clearance between the bottom of the first rotating shaft 201 and the rear buckle slope 401. Because the bottom arc of the first rotating shaft 201 abuts against the rear buckle protrusion 400, there is appropriate resistance when the first cover 200 is rotated open. As a result, this utility model only needs to use the interference fit structure between the rear buckle protrusion 400 and the first rotating shaft 201 to achieve a tighter sealing or opening and closing rotational connection of the first cover 200 to the first partition. Unlike the prior art, the opening and closing end of the first cover 200 does not need to be connected to the box body through a magnetic or snap-fit ​​structure in order to seal it tightly to the box body.

[0043] Similarly, the bottom middle portion of the side of the second cover 300 that is rotatably connected to the second partition extends downward to form a long rectangular second rotating shaft 301. The bottom of the second rotating shaft 301 has an arc surface, and a connecting blind hole 202 is provided on each side of the second rotating shaft 301 along its length direction. The side of the second partition that is rotatably connected to the second cover 300 is recessed inward towards its central axis to form a shaft groove 101. Two rear buckle protrusions 400 are symmetrically spaced along the side of the shaft groove 101 along its length direction, and the two rear buckle protrusions 400 are located within the rotation path of the second rotating shaft 301. An interference fit clearance is provided between each rear buckle protrusion 400 and the second rotating shaft 301. To facilitate rotatable connection with the second cover 300, a connecting through hole 102 is provided at each end of the shaft groove 101 along its length direction. The connection and rotation method of the second rotating shaft 301 and the shaft groove 101 are the same as above, and will not be described again here. Thus, the second cover 300 is tightly sealed or rotatedly connected to the second partition by the interference fit gap structure between the rear buckle protrusion 400 and the second rotating shaft 301.

[0044] Preferably, the first cover 200 is recessed to form a first compartment 203, which corresponds to the position of the first receiving chamber 103, and a lens 204 is disposed within the first compartment 203. The second cover 300 is recessed to form a second compartment 302, which corresponds to the position of the second receiving chamber 104, and a slot base 303 is disposed within the second compartment 302. The slot base 303 of this invention has two storage slots 3031, and a brush 3032 is disposed within each storage slot 3031.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
