Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a foldable cushioning and protective cardboard box. Background Technology

[0002] In modern logistics and commodity circulation, cushioning packaging boxes are typically used to protect goods from damage caused by impact, vibration, and compression during transportation. Currently, common protective packaging on the market often involves filling ordinary cardboard boxes with materials such as foam, bubble wrap, pearl cotton, or recycled paper.

[0003] However, this type of filling method has obvious structural defects. Because there is no effective fixed connection between the filler and the item or the inner wall of the cardboard box, the filler is prone to displacement and compression deformation during transportation, causing the item to shake inside the box and collide with the box wall, thus losing its original cushioning and protective function.

[0004] More importantly, this non-customized filling method is poorly adaptable to items of different sizes and shapes. For smaller items, a large amount of filler is required, resulting in material waste and increased costs; while for irregularly shaped items, the filler struggles to form a stable and effective enclosure and support, significantly reducing the protective effect. Therefore, designing a packaging box that can adapt to different item sizes and provide stable and reliable cushioning protection has become a pressing technical problem to be solved in this field.

[0005] Therefore, this utility model proposes a foldable cushioning and protective cardboard box to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of unstable internal filling, poor adaptability to items of different sizes, and unreliable cushioning protection in existing protective cardboard boxes, this utility model aims to provide a foldable cushioning protective cardboard box with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a foldable cushioning and protective cardboard box, including: an outer cardboard shell, and an inflatable cushioning layer disposed inside the outer cardboard shell; the foldable cushioning and protective cardboard box also includes a flexible partition.

[0008] The inflatable buffer layer is provided with an air inlet, and the inner wall of the inflatable buffer layer is fixedly connected with a Velcro surface.

[0009] Furthermore, the flexible partition is housed within the space enclosed by the inflatable buffer layer, and the edge of the flexible partition is fixedly connected with a hook surface. Through the detachable adhesion between the hook surface and the hook surface, the flexible partition can be flexibly fixed at any predetermined position inside the inflatable buffer layer.

[0010] Preferably, the top of the outer paper shell is integrally folded to form a top cover.

[0011] Preferably, double-sided adhesive tape for sealing the box body is fixed to the inner side of the top of the cover.

[0012] Preferably, the Velcro surfaces are arranged in a matrix along the height and width directions of the inner wall of the inflatable buffer layer.

[0013] Preferably, the magic hook surfaces are fixedly connected to the two ends and the bottom edge of the flexible partition.

[0014] Preferably, the flexible partition is a flexible sheet structure made of fabric or polymer composite material.

[0015] Preferably, the inflatable buffer layer is an independent airbag structure that can be separated from the outer paper shell.

[0016] Preferably, the width of the flexible partition is smaller than the width of the space enclosed by the inflatable buffer layer, so that the two ends of the flexible partition can be respectively bonded to the opposite inner walls of the inflatable buffer layer.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by setting a flexible partition that can be detachably bonded to any position on the inner wall of the inflatable buffer layer, the problem of the fixed internal space of the existing packaging box or the unstable protection of the filling material and poor adaptability to items of different sizes is solved. The technical effect of adaptive clamping and precise positioning of different items is achieved, which greatly improves the flexibility and versatility of the packaging.

[0019] 2. In this utility model, by combining the external inflatable buffer layer for absorbing impact with the internal flexible partition for limiting the items, the problem of the limited protective capacity of the traditional single buffer structure, which cannot effectively absorb external impact and suppress the shaking of internal items at the same time, is solved. The synergistic effect of internal and external double protection is achieved, ensuring the high stability and safety of the items during transportation. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 3 This utility model provides a foldable cushioning and protective cardboard box, which aims to solve the problems of poor adaptability of packaging cardboard boxes to items of different sizes and unstable protective structure in the prior art.

[0027] like Figure 1 and Figure 2 As shown, the foldable cushioning protective cardboard box includes an outer cardboard shell 1 and an inflatable cushioning layer 4 disposed inside the outer cardboard shell 1. The outer cardboard shell 1 forms the main support structure of the box body, while the inflatable cushioning layer 4 forms a surrounding basic cushioning protection. Specifically, an inflation port 7 is provided on the inflatable cushioning layer 4 for inflating or deflating the inflatable cushioning layer 4. Furthermore, Velcro 6 is fixedly connected to the inner wall of the inflatable cushioning layer 4 in a matrix pattern along the height and width directions of the inner wall of the inflatable cushioning layer 4. The arrangement provides a wide range of anchor points for the connection of components. The foldable cushioning protective cardboard box also includes a flexible partition 5 housed in the space enclosed by the inflatable cushioning layer 4. The edges of the flexible partition 5, specifically the two ends and the bottom edge of the flexible partition 5, are all fixedly connected with Velcro surfaces 8. The flexible partition 5 is detachably bonded to the Velcro surface 6 of the inner wall of the inflatable cushioning layer 4 through the Velcro surfaces 8 thereon, thereby flexibly fixing the flexible partition 5 in any predetermined position inside the inflatable cushioning layer 4 to form an adjustable limiting space.

[0028] To solve the above-mentioned technical problems, the flexible partition 5 of the foldable cushioning protective cardboard box forms an adjustable and detachable structural fit relationship between the hook surface 8 and the hook adhesive surface 6 on the inflatable cushioning layer 4.

[0029] Please refer to the following carefully. Figure 2 and Figure 3The Velcro surfaces 6, fixedly connected to the inner wall of the inflatable cushioning layer 4, are arranged in a matrix along the height and width of the inner wall of the inflatable cushioning layer 4. This large-area arrangement provides ample choice for the bonding of the Velcro surfaces 8. The flexible partition 5 is a flexible sheet structure made of fabric or polymer composite material, and its width is smaller than the width of the space enclosed by the inflatable cushioning layer 4. This dimensional relationship ensures that the two ends of the flexible partition 5 can be respectively bonded to the opposite inner walls of the inflatable cushioning layer 4, forming a limiting space in the middle for accommodating items. The edges of the flexible partition 5... Specifically, the two ends and bottom edge of the flexible partition 5 are all fixedly connected with hook surfaces 8. The hook surfaces 8 interlock with the pile fiber structure of the hook surface 6 through their hook-like structure, thereby achieving a firm bond. In the assembled state, the operator can attach the hook surfaces 8 on the flexible partition 5 to any corresponding position on the hook surface 6 on the inner wall of the inflatable buffer layer 4 according to the size of the item to be packaged. This adjustable connection structure between the flexible partition and the inner wall of the buffer layer achieved by hook and loop fasteners ensures the adaptive adjustment capability of the limiting space size.

[0030] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0031] As a preferred embodiment, please refer to Figure 1 The top of the outer cardboard shell 1 is integrally folded to form a top cover 2, which is used to close the opening end of the outer cardboard shell 1 after the item is placed inside.

[0032] As a further optimization of the above embodiment, a double-sided adhesive 3 is fixed to the inner side of the top of the top cover 2. The outer surface of the double-sided adhesive 3 is covered with a peelable protective layer, which is used to bond and fix the top cover 2 to the box body part of the outer paper shell 1 during packaging.

[0033] As another preferred embodiment, the inflatable cushioning layer 4 is an independent airbag structure that can be separated from the outer cardboard shell 1. This split design allows the outer cardboard shell 1 to be completely flattened and folded when the inflatable cushioning layer 4 is not installed, and allows the inflatable cushioning layer 4 to be replaced independently after damage.

[0034] Working principle: When in use, firstly, gas is injected into the inflatable buffer layer 4 through the air inlet 7, causing it to expand and fit tightly against the inner wall of the outer cardboard shell 1, forming a surrounding basic buffer structure. Then, according to the size of the item to be packaged, the flexible partition 5 is placed in the space enclosed by the inflatable buffer layer 4, and the Velcro hooks 8 at both ends and the bottom are attached to the Velcro hooks 6 on the inner wall of the inflatable buffer layer 4 as needed, thereby forming a size-matched limiting space inside the box.

[0035] After the item is placed in the limiting space, the top cover 2 is closed, and the box is sealed and fixed using the double-sided adhesive 3 on its top. During transportation, the outer inflatable buffer layer 4 is responsible for absorbing and dispersing the impact force from the outside, while the inner flexible partition 5 effectively clamps and limits the item by firmly adhering to the inflatable buffer layer 4, restricting its shaking inside the box. Through the synergistic effect of the inflatable buffer layer 4 and the flexible partition 5, this utility model solves the problem of poor adaptability of existing packaging to items of different sizes and unstable protective structure.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
