Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to an integrated packaging cushioning structure. Background Technology

[0002] Common packaging designs include box design and cushioning material design. Aside from dimensional matching, these are designed independently. Common box materials are corrugated cardboard, including A-flute, B-flute, E-flute, AB-flute, BE-flute, etc., and are generally square in shape. Cushioning materials are diverse, commonly including EPS foam cushioning, EPE foam cushioning, EPP foam cushioning, pulp cushioning, etc. For cushioning materials of irregularly shaped products, mold-forming technology is generally used. Cushioning materials produced using mold-forming technology can avoid the irregular shape of the product, especially protruding parts, thus preventing excessive impact and providing better cushioning.

[0003] EPS (Expanded Polystyrene) cushioning material is easy to mold, lightweight, and low-cost, making it widely applicable for cushioning packaging of precision equipment, household appliances, and other goods. However, its waste cannot be naturally weathered, and incineration produces harmful gases. EPE (Extractable Polyethylene) cushioning material, while recyclable and environmentally friendly, is expensive, thus primarily used for cushioning packaging of more valuable or fragile goods. Pulp molding has limited strength, and its cushioning performance is highly dependent on its shape; therefore, it is currently only suitable for cushioning packaging of small items such as small electronic products, fruits, and eggs, and not for heavier products. Designing a packaging structure that provides good cushioning performance while meeting environmental requirements is a pressing issue that needs to be addressed. Utility Model Content

[0005] Furthermore, the first buffer pad, the second buffer pad, the third buffer pad, and the fourth buffer pad are each provided with three creases, so that the buffer pad is folded along the creases to form a buffer pad with a rectangular cross section. Furthermore, a crease is provided on the fifth buffer pad, so that the fifth buffer pad forms a second upper cover plate and a buffer partition plate. Furthermore, the insert plate includes a first insert plate portion, a second insert plate portion, a third insert plate portion, a fourth insert plate portion, and a fifth insert plate portion, and a crease is provided between two adjacent insert plate portions. The third insert plate portion is provided with a first slot for inserting into the slots on the first buffer pad plate and the second buffer pad plate. After the insert plate is inserted into the packaging box, the second insert plate and the fourth insert plate are located at both ends inside the packaging box, the third insert plate is located on one side inside the packaging box, and the first insert plate and the fifth insert plate are located on the other side inside the packaging box and are in contact with the buffer partition in the same direction.

[0006] Furthermore, the first, second, third, and fourth buffer pads are also provided with elongated holes to reduce the rigidity of the buffer pads.

[0007] Furthermore, the fifth buffer pad has a second slot on its buffer partition for insertion into the slots on the first and second buffer pads. Furthermore, a crease is provided on the first upper cover, so that one side edge of the first upper cover forms a snap-fit ​​edge, which can be inserted into the gap between the first upper cover and the second upper cover of the packaging box to achieve the snap-fit ​​of the first upper cover.

[0008] Furthermore, the buffer pad is also equipped with clearance holes.

[0011] like Figure 1 and Figure 2 As shown, the integrated packaging cushioning structure disclosed in this application is made of corrugated cardboard 100 and includes: a first bottom plate 1, a second bottom plate 2, a first side plate 3, a second side plate 4, a third side plate 5, a fourth side plate 6, a first top cover plate 7, a first cushioning pad 8, a second cushioning pad, a third cushioning pad 9, a fourth cushioning pad 10, a fifth cushioning pad 11, and an insert plate 12. One end of the corrugated cardboard consists of the first bottom plate 1, the first side plate 3, and the first top cover plate 7 in sequence along the width direction, and a crease 14 is provided between two adjacent plates; Along the length of the corrugated cardboard, on one side of the first base plate 1, there are sequentially a first cushioning pad 8, a second base plate 2, and a second cushioning pad 9, with a groove 15 between adjacent plates; on one side of the first side plate 3, there are sequentially a second side plate 4, a third side plate 5, and a fourth side plate 6, with a crease 14 between adjacent plates; on one side of the first top cover plate 7, there are sequentially a third cushioning pad 10, a fifth cushioning pad 12, and a fourth cushioning pad 11, with a groove 15 between adjacent plates. A crease 14 is provided between two adjacent plates in the first buffer pad 8, the second side plate 4, and the third buffer pad 10; a crease 14 is provided between two adjacent plates in the second bottom plate 2, the third side plate 5, and the fifth buffer pad 10; a crease 14 is provided between two adjacent plates in the second buffer pad 9, the fourth side plate 6, and the fourth buffer pad 11; multiple creases 14 and slots 16 are provided on the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11. The corrugated cardboard 100 is folded along the corresponding creases to form a packaging box 200 and a first cushioning pad 17, a second cushioning pad 18, a third cushioning pad 19, a fourth cushioning pad 20 and a fifth cushioning pad 21 located inside the packaging box 200. The first cushioning pad 17 and the second cushioning pad 18 are located at the lower ends inside the packaging box 200, the third cushioning pad 19 and the fourth cushioning pad 20 are located at the upper ends inside the packaging box 200, and the fifth cushioning pad 21 is located on one side inside the packaging box 200. The insert plate 13 is inserted into the slot 16 of the buffer pad plate and forms a sixth buffer pad 22 on the other side of the packaging box 200, and a product accommodating space 23 is formed between the first to the sixth buffer pads.

[0012] Specifically, the integrated packaging cushioning structure disclosed in this application is constructed from a single piece of corrugated cardboard. This corrugated cardboard, through grooving and folding, forms a bottom plate, cover plate, side plates, cushioning pads, and inserts, thereby achieving product packaging and cushioning. Furthermore, the inserts and the packaging box body are cut from the same corrugated cardboard. This integrated packaging cushioning structure has the following advantages: From a cost perspective, the integrated packaging cushioning design eliminates the material costs of EPS, EPE, and EPP foam cushioning materials and pulp cushioning materials, eliminating the need for molding molds. From a packaging perspective, EPS, EPE, and EPP foam cushioning materials are difficult to degrade under natural conditions and are being phased out internationally. The structure disclosed in this application complies with relevant national requirements. From a public management perspective, the integrated packaging cushioning structure disclosed in this application avoids foam materials that are difficult to degrade under natural conditions, facilitating the recycling of product packaging.

[0013] Furthermore, the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11 are each provided with three creases 14, so that the buffer pads are folded along the creases to form a buffer pad with a rectangular cross section. Specifically, in this embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11 are each provided with three creases 14, so that the buffer pads are folded along the creases to form a rectangular buffer pad with a buffer cavity inside. A certain distance is left between the two buffer pads located at the same end of the packaging box to support the two ends of the product placed in the product containing space. The four buffer pads realize the buffering of the product in the product containing space in the vertical direction (the up and down direction when the packaging box is placed horizontally).

[0014] Furthermore, the fifth buffer pad 12 is provided with a crease 14, so that the fifth buffer pad 12 forms a second upper cover 24 and a buffer partition 25. Specifically, in this embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the fifth buffer pad 12 has a crease 14, which forms the second upper cover 24 and the buffer partition 25. The third buffer pad 10 and the fourth buffer pad 11 have snap-fit ​​grooves 36. After the corrugated cardboard is folded into a packaging box, the second upper cover is located on one side of the packaging box and is on the same side as the first upper cover to achieve the snap-fit ​​of the packaging box. The buffer partition 25 can pass through the snap-fit ​​groove 36 and be placed inside the packaging box, so that the buffer partition 25 and the corresponding side plate (third side plate) form a buffer cavity, thereby buffering one side of the product receiving cavity.

[0015] Furthermore, the insert plate 13 includes a first insert plate portion 26, a second insert plate portion 27, a third insert plate portion 28, a fourth insert plate portion 29, and a fifth insert plate portion 30, and a crease 14 is provided between two adjacent insert plate portions. The third insert plate portion 28 is provided with a first slot 31 for inserting into the slots 16 on the first buffer pad 8 and the second buffer pad 9. After the insert plate 13 is inserted into the packaging box 200, the second insert plate portion 27 and the fourth insert plate portion 29 are located at both ends inside the packaging box, the third insert plate portion 28 is located on one side inside the packaging box, and the first insert plate portion 26 and the fifth insert plate portion 30 are located on the other side of the packaging box and are in contact with the buffer partition 25 in the same direction.

[0016] Specifically, in this embodiment, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the insert plate 13 is a long strip. The insert plate 13 has a first insert plate portion 26, a second insert plate portion 27, a third insert plate portion 28, a fourth insert plate portion 29, and a fifth insert plate portion 30 arranged sequentially from one end to the other through grooves 15 and creases 14. A first slot 31 is provided on one side of the third insert portion 28 near both ends. The first slot 31 can be inserted into the longitudinally arranged slots 16 on the first buffer pad plate 8 and the second buffer pad plate 9. The second insert portion 27 and the fourth insert portion 29 have plug structures on both sides. Laterally arranged... The slots 16 are designed so that, after the corrugated cardboard is folded into a packaging box, the plug structures 37 on both sides of the second and fourth plug-in portions 27 and 29 can be inserted into the horizontally arranged slots 16 on the first, second, third, and fourth buffer pads, respectively. This allows the buffer pads to limit the second and fourth plug-in portions, forming a buffer cavity between them and the corresponding side panels (the second and fourth side panels). In other words, the mutual interlocking of the second and fourth plug-in portions with the first, second, third, and fourth buffer pads provides buffering at both ends of the product's containing space. After the inserts are inserted into the packaging box, the third plug-in portion 28 is located on one side inside the packaging box, and its two ends can be inserted into the vertically arranged slots 16 on the first, second, third, and fourth buffer pads. The third plug-in portion 28 forms a buffer cavity with the corresponding side panel (the first side panel), thus providing buffering on one side of the product's containing space.

[0017] Furthermore, the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11 are also provided with elongated holes 32 for reducing the rigidity of the buffer pads.

[0018] Specifically, in this embodiment, such as Figure 1 , Figure 7 and Figure 8 As shown, an elongated hole 32 is provided between the two creases of the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11. When the first buffer pad 8, the second buffer pad 9, the third buffer pad 10, and the fourth buffer pad 11 are folded along the creases to form a buffer pad with a rectangular cross-section, the elongated hole 32 is located on the inner side wall of the buffer pad (the side wall is the structure in the height direction of the packaging box, that is, the vertical direction when the packaging box is set horizontally). Since the corrugations of the corrugated cardboard are longitudinal (vertical direction) in this direction, it is easy to cause the structural rigidity of this part to be too large. Opening the elongated hole 32 here can reduce the rigidity and increase the cushioning performance.

[0019] Furthermore, the buffer partition 25 of the fifth buffer pad 12 is provided with a second slot 33 for insertion into the slots 16 on the first buffer pad 8 and the second buffer pad 9.

[0020] Specifically, on the buffer partition 25 of the fifth buffer pad 12, an opening groove is provided on one side of the edge near both ends to form a second slot 33. After the corrugated cardboard is folded along the creases, the second slot 33 can be inserted into the slots 16 on the first buffer pad 8 and the second buffer pad 9. That is, the two ends of the buffer partition 25 are engaged with the buffer pads on both sides through the second slot 33, so that a certain buffer cavity is formed between the buffer partition 25 and the side plate (third side plate) on the same side, thereby effectively protecting the product.

[0021] Furthermore, the first upper cover plate 7 is provided with a crease 14, so that one side edge of the first upper cover plate 7 forms a snap-fit ​​edge 34, which can be inserted into the gap between the first upper cover plate 7 and the second upper cover plate 24 of the packaging box to achieve the snap-fit ​​of the first upper cover plate 7.

[0022] Specifically, such as Figure 1 and Figure 3 As shown, a crease 14 is provided on the edge of the first upper cover plate 7 near one side, so that the edge of the first upper cover plate 7 can be bent relative to the main body of the first upper cover plate 7 to form a snap-fit ​​edge 34. After the product packaging is completed, the snap-fit ​​edge 34 can be inserted into the gap between the first upper cover plate 7 and the second upper cover plate 24 to realize the snap-fit ​​of the first upper cover plate 7 and prevent the upper cover plate from opening automatically. In this embodiment, the snap-fit ​​edge 34 and the buffer partition 25 are both inserted into the snap-fit ​​grooves 36 on the third buffer pad 10 and the fourth buffer pad 11 to achieve the clamping and closing of the upper cover plate.

[0023] Furthermore, the buffer pad is also provided with clearance holes 35.

[0024] Specifically, such as Figure 6 As shown, clearance holes 35 are provided at positions on the buffer pad that may interfere with the product, so as to allow the buffer pad to avoid the relevant positions of the product, thereby enabling the product to be effectively placed in the product holding space. In this embodiment, the buffer partition 25 of the fifth buffer pad 12 is provided with rectangular clearance holes 35 to avoid the relevant positions of the product.

[0025] Furthermore, an adhesive edge is provided at the end of the first side plate 3 so that the first side plate 3 and the fourth side plate 6 can be bonded together after the corrugated cardboard is folded into a packaging box. At the same time, after the corrugated cardboard is folded into a packaging box, the two bottom plates are sealed and fixed together with tape.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
