Description

Technical Field

[0001] This disclosure relates to the technical field of packaging boxes, and in particular to an anti-wrinkle box structure and storage box. Background Technology

[0002] In the field of paper box and storage box manufacturing, the forming of curved structures has always been a technical challenge. When processing curved surfaces in traditional paper storage boxes, the complex curves formed at the corners due to structural transitions make these areas prone to quality defects. Because the paper or cardboard material of the box exhibits anisotropic properties when bent, the stress states on the inner and outer sides of the corners differ significantly; the outer part, subjected to tensile force, is prone to thinning and tearing, while the inner part, subjected to compressive force, causes wrinkles on the inner surface, severely compromising the structural integrity and surface stability of the box.

[0003] Existing solutions for preventing wrinkles at corners have significant limitations. Most storage boxes typically use molds to modify the surface precision at corners, but this involves high energy consumption, low processing efficiency, and large equipment investment. Furthermore, controlling the surface precision through mold hot pressing makes it difficult to maintain stability, leading to unstable surface structure quality and wrinkles at the corners, significantly reducing the overall aesthetics and lifespan of the storage box. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a wrinkle-resistant box structure and storage box that prevents wrinkles at the corners of the box and is easy to disassemble.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A wrinkle-resistant box structure includes a box body and a cover plate. The box body includes a bottom plate, a side plate, and a bending plate. The cover plate is movably connected to the box body. The side plate and the bending plate are perpendicularly connected to the side of the bottom plate. The first end of the bending plate is connected to the first side of the side plate, and the second end of the bending plate is connected to the second side of the side plate.

[0007] The bending plate is characterized in that it has a first bending portion and a second bending portion, which are arranged opposite to each other. The first bending portion has a plurality of spaced-apart first grooves, and the second bending portion has a plurality of spaced-apart second grooves. Each first groove extends along the width direction of the bending plate, and each second groove extends along the width direction of the bending plate. The width direction of the bending plate is perpendicular to the plane of the base plate.

[0008] In one embodiment, the cover plate is provided with a first magnetic surface, a second magnetic surface and a sealing surface. The first magnetic surface is provided with a first magnetic element, and the second magnetic surface is provided with a second magnetic element. The first magnetic surface is attached to the side of the bottom plate through the first magnetic element, and the second magnetic surface is attached to one side of the side plate through the second magnetic element. The sealing surface covers the box body.

[0009] In one embodiment, the cover is detachably connected to the housing.

[0010] In one embodiment, the depth of each of the first cutting grooves is equal to the depth of each of the second cutting grooves.

[0011] In one embodiment, the cover plate is a one-piece molded structure.

[0012] In one embodiment, the depth of the first groove and the depth of the second groove are 50% to 70% of the thickness of the bent plate.

[0013] In one embodiment, both the first and second cutting grooves are arc-shaped structures.

[0014] In one embodiment, the bending plate is further provided with a protective layer, which is disposed on the side opposite to the first cutter groove.

[0015] In one embodiment, the base plate, the side plate, and the bent plate are connected in sequence to form a placement cavity.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] The cover plate is movably connected to the box body, allowing it to be rotated to cover the box body. The box body includes a bottom plate, side plates, and a bent plate. The side plates and bent plates are perpendicularly connected to the sides of the bottom plate, with the first end of the bent plate connected to the first side edge of the side plate and the second end connected to the second side plate, creating a semi-enclosed shape for the box body. The first bent plate has a first bend and a second bend, positioned opposite each other. When the first end of the bent plate is connected to the first side edge of the side plate, a first bend is formed at a corner on one side of the bent plate; similarly, when the second end of the bent plate is connected to the second side edge of the side plate, a second bend is formed at a corner on one side of the bent plate. A first groove is formed in the first bend and a second groove is formed in the second bend, both extending to the thickness direction of the bent plate. The first and second bends are respectively provided with a first groove and a second groove, which extend along the curvature of the curved surface. This prevents wrinkles from appearing on the wall of the bent plate when it is bent, thus ensuring the integrity of the box structure and the surface stability of the bent plate.

[0027] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0028] like Figures 1 to 2 As shown, an embodiment of the anti-wrinkle box body 100 structure 10 includes a box body 100 and a cover plate 200. The box body 100 includes a bottom plate 110, a side plate 120 and a bending plate 130. The cover plate 200 is movably connected to the box body 100. The side plate 120 and the bending plate 130 are perpendicularly connected to the side of the bottom plate 110. The first end of the bending plate 130 is connected to the first side of the side plate 120, and the second end of the bending plate 130 is connected to the second side of the side plate 120.

[0029] The bending plate 130 is provided with a first bending portion 1310 and a second bending portion 1320, which are arranged opposite to each other. The first bending portion 1310 has a plurality of spaced first grooves 1311, and the second bending portion 1320 has a plurality of spaced second grooves 1321. Each first groove 1311 extends along the width direction of the bending plate 130, and each second groove 1321 extends along the width direction of the bending plate 130. The width direction of the bending plate 130 is perpendicular to the plane of the base plate 110.

[0030] In this embodiment, the cover plate 200 is movably connected to the box body 100, so that the cover plate 200 can be rotated to cover the box body 100. The box body 100 includes a bottom plate 110, side plates 120, and a bending plate 130; the side plates 120 and the bending plate 130 are perpendicularly connected to the side of the bottom plate 110, with the first end of the bending plate 130 connected to the first side of the side plate and the second end of the bending plate 130 connected to the second side plate 120, thus forming a semi-enclosed shape for the box body 100. Furthermore, the first bending plate 130 is provided with a first bending portion 1310 and a second bending portion 1320, with the first bending portion 1310 and the second bending portion 1320 being disposed opposite to each other; when the first end of the bending plate 130 is connected to the first side edge of the side plate 120, a first bending portion 1310 will be formed on one side of the bending plate 130 at the corner; similarly, when the second end of the bending plate 130 is connected to the second side edge of the side plate 120, a second bending portion 1320 will be formed on one side of the bending plate 130 at the corner, by opening a first cutting groove 1311 in the first bending portion 1310 and a second cutting groove 1321 in the second bending portion 1320, while the first cutting groove 1311 and the second cutting groove 1321 extend along the width direction of the bending plate 130; due to the first The first bending portion 1310 and the second bending portion 1320 are respectively provided with a first groove 1311 and a second groove 1321, which extend along the thickness direction of the bending plate 130. This prevents wrinkles from forming on the wall of the bending plate 130 when the first bending portion 1310 and the second bending portion 1320 are in a bent state due to bending, thus ensuring the structural integrity of the box 100 and the surface stability of the bending plate 130. It should be noted that the thickness direction of the bending plate 130 is the horizontal direction perpendicular to the base plate 110.

[0031] In another embodiment, the groove formed by the first cutting groove 1311 and the second cutting groove 1321 makes the surface of the bending plate 130 more stable by filling the groove.

[0032] Combination Figure 1 and Figure 2 As shown, the cover plate 200 is further provided with a first magnetic surface 210, a second magnetic surface 220 and a sealing surface 230. The first magnetic surface 210 is provided with a first magnetic element 211, and the second magnetic surface 220 is provided with a second magnetic element 221. The first magnetic surface 210 is attached to the side of the bottom plate 110 through the first magnetic element 211, and the second magnetic surface 220 is attached to one side of the side plate 120 through the second magnetic element 221. It is understood that by providing a first magnetic suction element 211 on the cover plate 200 and a second magnetic suction element 221 on the second magnetic suction surface 220, the first magnetic suction surface 210 can adhere to the side of the bottom plate 110 through the first magnetic suction element 211, so that the first magnetic suction surface 210 of the cover plate 200 can be firmly attached to the side of the bottom, and the second magnetic suction surface 220 can adhere to the side plate 120 through the second magnetic suction element 221. At the same time, the sealing surface 230 covers the box body 100, so that the cover plate 200 can wrap the box body 100 through the first magnetic suction element 211 and the second magnetic suction element 221.

[0033] like Figure 1 and Figure 2 As shown, the cover plate 200 is further detachably connected to the box body 100. It can be understood that by detachably connecting the cover plate 200 to the box body 100, the box body 100 can be separated from the cover plate 200 in a detachable manner. Users can use the box body 100 independently or in combination with the cover plate 200, increasing the flexibility of use. At the same time, the magnetic design of the cover plate 200 ensures a stable connection and prevents accidental opening.

[0034] Combination Figure 1 and Figure 3 As shown, in one embodiment, the depth of each of the first grooves 1311 is equal to the depth of each of the second grooves 1321. It can be understood that by limiting the depth of the first groove 1311 to be equal to the depth of the second groove 1321, the deformation on both sides of the bent plate 130 is ensured to be consistent during bending, thereby keeping the first bent portion 1310 and the second bent portion 1320 as flat as possible, avoiding uneven bending caused by different depths, and improving the stability and aesthetics of the overall structure.

[0035] like Figure 1As shown, in one embodiment, the cover plate 200 is a one-piece molded structure. In this embodiment, the cover plate 200 is made of high-strength material, ensuring the durability and pressure resistance of the overall structure. The one-piece molded design reduces splicing gaps, improves waterproof and dustproof effects, and further enhances the sealing performance and service life of the box body 100. The one-piece molded cover plate 200 not only improves the overall aesthetics but also simplifies the production process and reduces manufacturing costs.

[0036] like Figure 1 As shown, in one embodiment, the depth of the first groove 1311 and the depth of the second groove 1321 are 50% to 70% of the thickness of the bending plate. It can be understood that by limiting the depth of the first groove 1311 and the second groove 1321 to 50% to 70% of the thickness of the bending plate, sufficient deformation space is ensured during folding to eliminate stress concentration, while avoiding excessive depth of the first groove 1311 and the second groove 1321, which could lead to insufficient structural strength of the bent portion. In this example, when the depth of the first groove 1311 and the second groove 1321 reaches 50% of the thickness of the bending plate 130, a clear crease line can be formed in the bent portion during folding, effectively dispersing bending stress; while the design of a depth not exceeding 70% retains sufficient material thickness in the bent portion, ensuring structural stability after repeated opening and closing.

[0037] Combination Figure 1 and Figure 3 As shown, in one embodiment, the first groove 1311 and the second groove 1321 are arc-shaped structures. It can be understood that designing the first groove 1311 and the second groove 1321 as arc-shaped structures can better disperse the stress during bending, reduce stress concentration points, and thus extend service life. Furthermore, the arc-shaped grooves make the bending process smoother, reduce bending resistance, and improve the user experience. This design not only enhances the durability of the structure but also maintains the overall aesthetics.

[0038] like Figure 1 As shown, in one embodiment, the bending plate 130 is further provided with a protective layer, which is disposed on the side opposite to the first cutter groove 1311. In this embodiment, the protective layer is made of a wear-resistant material, effectively preventing wear on the bending plate 130 during bending and extending its service life. The protective layer not only improves the durability of the bending plate 130 but also maintains its smooth and aesthetically pleasing surface, further enhancing the user experience. At the same time, the design of the protective layer does not affect the normal use of the bending plate 130, ensuring functional integrity and ease of operation.

[0039] like Figure 1As shown, in another embodiment, the base plate 110, the side plate 120, and the bent plate 130 are sequentially connected to form a placement cavity 140. It can be understood that connecting the base plate 110, side plate 120, and bent plate 130 together to form a box body 100, while the semi-enclosed structure forms the placement cavity 140, providing sufficient space to accommodate various items.

[0040] Combination Figure 1 As shown, this application also provides a storage box, including the anti-wrinkle box body 100 structure 10 described in any of the above embodiments. It can be understood that by providing a first groove 1311 and a second groove 1321 respectively for the first bending portion 1310 and the second bending portion 1320, and by extending the first groove 1311 and the second groove 1321 along the curvature direction of the curved surface, when the first bending portion 1310 and the second bending portion 1320 are in a bent state, the spaced first grooves 1311 and the second groove 1321 prevent wrinkles from appearing on the wall of the bent plate 130 due to bending.
