Description

Technical Field

[0001] This utility model relates to the field of cardboard boxes, and specifically to a cushioning cardboard box. Background Technology

[0002] Existing cardboard boxes generally suffer from insufficient cushioning protection when transporting fragile items. Traditional cardboard boxes mostly use a single cardboard structure, typically achieving cushioning through thickened cardboard or internal filling with materials such as foam or bubble wrap. However, these methods have shortcomings: Firstly, foam and other materials placed directly inside the box may shift during transportation. Without a supporting structure for the foam, when the outer cardboard is compressed, the foam cannot provide adequate support, ultimately directly compressing the items inside. Secondly, simply thickening the cardboard increases the weight and cost of the box.

[0003] Therefore, in order to overcome the shortcomings of existing technologies, it is necessary to design a simple cushioning carton. Utility Model Content

[0004] This invention provides a cushioning cardboard box to address the problems of existing technologies.

[0005] The objective of this utility model can be achieved through the following technical solution: A cushioned cardboard box includes: an outer cardboard box, an inner cardboard box, four sets of air columns, and four sets of interlocking cushioning cardboard assemblies. The inner cardboard box is disposed inside the outer cardboard box and a buffer zone is provided between them. The four sets of interlocking cushioning cardboard assemblies are disposed within the buffer zone. Each interlocking cushioning cardboard assembly includes an upper cardboard, a lower cardboard, a first diagonal interlocking cardboard, and a second diagonal interlocking cardboard. The first diagonal interlocking cardboard and the second diagonal interlocking cardboard are interlocked in the middle and form an X shape. The upper cardboard is interlocked at the upper part of the first diagonal interlocking cardboard and the second diagonal interlocking cardboard. The lower cardboard is interlocked at the lower part of the first diagonal interlocking cardboard and the second diagonal interlocking cardboard. The air columns are disposed within the four corners of the buffer zone and located adjacent to the interlocking cushioning cardboard assemblies.

[0006] In a further improvement, the first inclined insert cardboard has a slot 1 in the middle, and the upper and lower ends of the first inclined insert cardboard are respectively provided with an inclined slot 1. The second inclined insert cardboard has a slot 2 in the middle, and the upper and lower ends of the second inclined insert cardboard are respectively provided with an inclined slot 2. The slot 2 and the slot 1 are interlocked and connected. The upper cardboard has an inclined slot 3 on both sides, and the inclined slot 3 of the upper cardboard is respectively interlocked and connected to the inclined slot 1 at the upper end of the first inclined insert cardboard and the inclined slot 2 at the upper end of the second inclined insert cardboard. The lower cardboard has an inclined slot 4 on both sides, and the inclined slot 4 of the lower cardboard is respectively interlocked and connected to the inclined slot 1 at the lower end of the first inclined insert cardboard and the inclined slot 2 at the lower end of the second inclined insert cardboard.

[0007] As a further improvement, the edge of the air column is set with a rounded chamfer.

[0008] As a further improvement, the upper part of the outer cardboard box is provided with four sets of paper cover plates.

[0009] In a further improvement, the outer cardboard box, inner cardboard box, upper cardboard, lower cardboard, oblique insert cardboard one, and oblique insert cardboard two are all corrugated cardboard.

[0010] Compared with existing technologies, the beneficial effects of this new type of cushioned cardboard box are as follows: By combining the rigid support and force dispersion of the X-shaped cardboard frame with the elastic cushioning of the air column, it can resist the squeezing and collision from the side and absorb the impact of falling from the corners, thus solving the problem of limited cushioning area in traditional cardboard boxes; the nesting of inner and outer boxes with the three-dimensional support of the cushioning components improves the overall deformation resistance of the cardboard box.

[0013] The following describes the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0014] Example 1 A cushioning cardboard box includes: an outer cardboard box 1, an inner cardboard box 2, four sets of air columns 3, and four sets of interlocking cushioning cardboard assemblies 4. The inner cardboard box 2 is disposed inside the outer cardboard box 1 and a buffer zone 11 is provided between them. The four sets of interlocking cushioning cardboard assemblies 4 are disposed within the buffer zone 11. Each interlocking cushioning cardboard assembly 4 includes an upper cardboard 41, a lower cardboard 42, a first diagonal interlocking cardboard 43, and a second diagonal interlocking cardboard 44. The first diagonal interlocking cardboard 43 and the second diagonal interlocking cardboard 44 are interlocked in the middle and form an X shape. The upper cardboard 41 is interlocked at the upper part of the first diagonal interlocking cardboard 43 and the second diagonal interlocking cardboard 44, and the lower cardboard 42 is interlocked at the lower part of the first diagonal interlocking cardboard 43 and the second diagonal interlocking cardboard 44. The air columns 3 are disposed within the four corners of the buffer zone 11 and are located adjacent to the interlocking cushioning cardboard assemblies 4.

[0015] As shown in the figure, Figures 1-3 As shown, the working principle of this utility model is as follows: The outer cardboard box 1 and the inner cardboard box 2 form a ring-shaped buffer zone 11. The inner cardboard box 2 is used to directly place items, while the outer cardboard box 1 serves as an outer protective layer. Together, they form a load-bearing structure. Four sets of interlocking buffer cardboard assemblies 4 are distributed along the four sides of the inner cardboard box 2 within the buffer zone 11. In each set, the first and second diagonal cardboard assemblies 43 and 44 are interlocked in the middle in an X-shape, forming a three-dimensional support frame using the principle of triangular stability. The upper cardboard 41 and the lower cardboard 42 are respectively interlocked at the upper and lower ends of the X-shaped frame, further enhancing the overall rigidity of the frame and dispersing the squeezing and impact forces from the sides. At the same time, air columns 3 are set at the four corners of the buffer zone 11. The air columns 3 have elastic deformation capabilities and can absorb the impact forces from the corners, complementing the interlocking buffer cardboard assemblies 4 and covering the sides and corners of the cardboard box that are prone to impact.

[0016] By combining the rigid support and force dispersion of the X-shaped cardboard frame with the elastic cushioning of the air column, it can resist the squeezing and collision from the side and absorb the impact of falling from the corners, thus solving the problem of limited cushioning area in traditional cardboard boxes; the nesting of inner and outer boxes with the three-dimensional support of the cushioning components improves the overall deformation resistance of the cardboard box.

[0017] As a further preferred embodiment, the first inclined insert cardboard 43 has a slot 431 in the middle, and the upper and lower ends of the first inclined insert cardboard 43 are respectively provided with inclined slots 432. The second inclined insert cardboard 44 has a slot 441 in the middle, and the upper and lower ends of the second inclined insert cardboard 44 are respectively provided with inclined slots 442. The second slot 441 and the first slot 431 are interlocked. The upper cardboard 41 has inclined slots 411 on the left and right sides. The inclined slots 411 of the upper cardboard 41 are respectively interlocked with the inclined slots 432 at the upper end of the first inclined insert cardboard 43 and the inclined slots 442 at the upper end of the second inclined insert cardboard 44. The lower cardboard 42 has inclined slots 421 on the left and right sides. The inclined slots 421 of the lower cardboard 42 are respectively interlocked with the inclined slots 432 at the lower end of the first inclined insert cardboard 43 and the inclined slots 442 at the lower end of the second inclined insert cardboard 44. The slot 431 of the first inclined insert cardboard 43 and the slot 441 of the second inclined insert cardboard 44 interlock to form a stable X-shaped cross structure; the inclined slots 432 and 442 at the upper and lower ends of the inclined insert cardboard interlock with the inclined slots 411 of the upper cardboard 41 and 421 of the lower cardboard 42, so that the upper and lower cardboard and the X-shaped frame form an integral load-bearing structure. The slots can be quickly spliced, improving production efficiency and facilitating disassembly and recycling. The slots fit together to make the cardboards tightly connected and not easy to separate under stress.

[0018] As a further preferred embodiment, the edges of the air column 3 are rounded and chamfered. The rounded structure makes the deformation of the air column smooth when subjected to force, improving the buffering effect in the corner area.

[0019] As a further preferred embodiment, the upper end of the outer cardboard box 1 is provided with four sets of paper cover plates 5. The four sets of paper cover plates 5 can be folded and overlapped to form a closed top structure to prevent dust from entering.

[0020] As a further preferred embodiment, the outer cardboard box 1, the inner cardboard box 2, the upper cardboard 41, the lower cardboard 42, the first diagonal insert cardboard 43, and the second diagonal insert cardboard 44 are all corrugated cardboard. The wavy corrugated structure inside the corrugated cardboard itself is elastic, and can absorb energy through deformation when subjected to external force, and has high strength.

[0021] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
