[0035] Referring to Figures 1-8 ,

[0036] A box cover structure comprises a cover part 11, a first bending part 12 and a second bending part 13.

[0037] The cover part 11 is used to form a containing cavity 111. The cover part 11 is a shell structure of a block, and the containing cavity 111 is a cavity with an open lower end surrounded by the inner wall of the cover. The first bending part 12 is arranged at the bottom of the cover part 11, and the first bending part 12 is directly connected with the cover part 11. The second bending part 13 is connected with the first bending part 12. The first bending part 12 and the second bending part 13 are both thin-walled plates, and the materials of the first bending part 12, the second bending part 13 and the cover part 11 are the same, which are all PET.

[0038] In this embodiment, the direction away from the containing cavity 111 means moving away from the containing cavity 111, and the first bending part 12 is arranged at the bottom of the cover part 11, so the extension direction of the first bending part 12 is laterally away from the containing cavity 111 and downwardly away from the containing cavity 111, and it can also be partially laterally and partially downwardly away from the containing cavity 111.

[0039] When the extension direction of the first bending part 12 is partially laterally and partially downwardly away from the containing cavity 111, the extension direction of the first bending part 12 can be inclined or arc-shaped, as long as the extension direction of the first bending part 12 is away from the containing cavity 111.

[0040] The direction of the second bending part 13 is the same.

[0041] The first bending part 12 and the second bending part 13 form an abutting surface 15 composed of at least one curved surface and at least one flat surface. The abutting surface 15 is located at the end of the first bending part 12 and the second bending part 13 away from the accommodating cavity 111. The curved surface is a curved surface, and the flat surface is one or both of a relatively horizontal plane and an inclined plane.

[0042] Therefore, the first bending part 12 and the second bending part 13 are one or more of a flat surface, an inclined surface, and a curved surface.

[0043] In some specific embodiments of the abutting surface 15, the first bending part 12 forms an inclined surface, and the second bending part 13 forms a curved surface; or the first bending part 12 forms a curved surface, and the second bending part 13 forms an inclined surface; or the first bending part 12 forms a flat surface, and the second bending part 13 forms a curved surface; or the first bending part 12 forms an inclined surface and a curved surface, and the second bending part 13 forms an inclined surface; or the first bending part 12 forms a flat surface and a curved surface, and the second bending part 13 forms an inclined surface.

[0044] The purpose of the abutting surface 15 is to form a surface that does not hurt the hand at the bottom of the box cover structure 1. When transferring a plurality of box cover structures 1 stacked together, the hand contacts the abutting surface 15 to achieve the transfer, at which time the abutting surface 15 in the present application can achieve that the hand is not hurt during the transfer process. At the same time, during the use of the box cover structure 1, there will also be a situation that the box cover structure 1 needs to be buckled with other containers and separated, and the abutting surface 15 can also play a role of not hurting the hand when the box cover structure 1 is separated from other structures.

[0045] In some other embodiments, based on the above-mentioned embodiments, the box cover structure further comprises a third bending part 14 connected to the second bending part 13, and the third bending part 14 extends in a direction close to the accommodating cavity 111. The first bending part 12, the second bending part 13, and the third bending part 14 jointly constitute the abutting surface 15.

[0046] The third bending part 14 extends in a direction close to the accommodating cavity 111, which can be close inwardly, upwardly, or partially inwardly and partially upwardly.

[0047] Therefore, the first bending part 12, the second bending part 13, and the third bending part 14 are one or more of a flat surface, an inclined surface, and a curved surface.

[0048] In some specific embodiments of the abutting surface 15, the first bending part 12 forms an inclined surface, the second bending part 13 forms an arc surface, and the third bending part 14 forms an inclined surface; or the first bending part 12 forms an arc surface, the second bending part 13 forms an inclined surface, and the third bending part 14 forms an inclined surface; or the first bending part 12 forms a flat surface, the second bending part 13 forms an arc surface, and the third bending part 14 forms an inclined surface and an arc surface; or the first bending part 12 forms an inclined surface and an arc surface, the second bending part 13 forms an inclined surface, and the third bending part 14 forms an arc surface; or the first bending part 12 forms a flat surface and an arc surface, the second bending part 13 forms an inclined surface, and the third bending part 14 forms an arc surface.

[0049] The above will not be described one by one.

[0050] In some other embodiments, based on the above embodiments, the outer wall surface of the cover part 11 gradually flares from top to bottom.

[0051] In some other embodiments, based on the above embodiments, the first bending part 12 is indirectly connected with the cover part 11, and the box cover structure further comprises: a connecting part 16 connected with the cover part 11; the connecting part 16 extends in a direction away from the containing cavity 111 and is connected with the first bending part 12 at a connecting position. The purpose of the connecting part 16 is to form a transition between the abutting surface 15 and the cover part 11, so that the abutting surface 15 is away from the cover part 11, thereby avoiding the fingers of the hand from touching the cover part 11 when the abutting surface 15 is held up with the hand, and affecting the area of the finger pad of the finger in contact with the abutting surface 15.

[0052] In some other embodiments, based on the above embodiments, the connecting part 16 extends in two directions away from the containing cavity 111, so that the connecting position is on the lower side of the cover part 11.

[0053] In some other embodiments, based on the above embodiments, the cover part 11 is configured in a square body structure.

[0054] In some other embodiments, a cake box is provided, which comprises the box cover structure 1 in any one of the above embodiments and a box bottom structure 2 for buckling with the box cover structure 1. The box bottom structure 2 comprises a disc part 21 and an extension part 22; the disc part 21 is used to form a storage cavity 211; the extension part 22 is connected with the disc part 21 and extends in a direction away from the storage cavity 211; the box cover structure 1 further forms a plurality of clamping parts 18, which protrude close to the containing cavity 111; when the box cover structure 1 and the box bottom structure 2 are buckled, the clamping parts 18 are located below the extension part 22. The disc part 21 is a shell structure in this embodiment, preferably a cuboid shell structure. The extension part 22 is a thin plate structure, and the materials of the extension part 22 and the disc part 21 are the same, both being PP.

[0055] Specifically, the extension part 22 is provided with a positioning groove 23; the connecting part 16 is provided with a positioning protrusion 17; when the box cover structure 1 and the box bottom structure 2 are buckled, the positioning protrusion 17 abuts against the positioning groove 23. The positioning groove 23 is an arc-shaped groove, and the shape of the positioning protrusion 17 matches the shape of the positioning groove 23.

[0056] In some embodiments, when the box cover structure 1 and the box bottom structure 2 are buckled, the extension part 22 abuts against the abutting part. The clamping part 18 is arranged on the connecting part 16.

[0057] Specifically, the cover part 11 includes two long sides 112 and two short sides 113; the positioning protrusion 17 is arranged on the connecting part 16 at the short side 113; and the clamping part 18 is arranged on both ends of the connecting part 16 at the long side 112 and on both ends of the connecting part 16 at the short side 113.

[0058] In other embodiments, the cover part 11 is composed of an inner shell 114 and an outer shell 115. After the inner shell 114 is inserted into the outer shell 115, the inner shell 114 and the outer shell 115 are in interference fit, so that the inner shell 114 and the outer shell 115 are fixed together. The height of the inner shell 114 is lower than the height of the outer shell 115, so that in actual use, the top of the cover part 11 has strong supporting force, and the cover part 11 can be directly pinched at the top, and the cover part 11 will not be deformed because the top walls of the inner shell 114 and the outer shell 115 are adjacent.
