Description

Technical Field

[0001] This utility model relates to the technical field of all-paper heavy-duty packaging, and in particular to an all-paper heavy-duty packaging with high load-bearing capacity and resistance to deformation. Background Technology

[0002] In modern logistics and transportation, the high strength, lightweight, and deformation resistance of packaging materials are receiving increasing attention. Traditional heavy-duty packaging often uses wood or plastic as the main material, but these materials are susceptible to moisture, deformation, or damage during transportation and storage. Furthermore, the demands for environmental protection and sustainable development are driving the packaging industry to shift towards all-paper and environmentally friendly materials.

[0003] For example, Chinese patent document CN205023052U discloses a heavy-duty packaging carton, which includes a paper packaging carton body. A composite board is fixed on the inner surface of the side wall of the carton body, or a composite board is fixed on both the inner surface of the side wall of the carton body and the bottom surface of the carton body. The composite board is made of a wooden frame and a panel paper glued together.

[0004] Currently, some countries or regions are looking to achieve higher environmental protection requirements: reduce the use of wood products; and make it easier to recycle packaging waste, thus requiring the use of all-paper packaging.

[0005] However, all-paper packaging solutions with a load-bearing capacity of over 1 ton present several unresolved issues: When loaded with forklifts, the all-paper packaging is prone to compression and deformation at the forklift entry point when the weight exceeds 1 ton. Furthermore, the paper pallet may bend and deform under pressure, affecting the overall structural strength of the packaging. Both of these problems can lead to packaging collapse, causing serious product accidents and even personal injury incidents.

[0006] For the reasons mentioned above, current high-load-bearing packaging primarily uses a structure of cardboard boxes and wooden pallets. By using sturdier wooden pallets, the packaging strength is enhanced, resisting damage and deformation during logistics, thereby reducing packaging accidents. However, the use of wood has obvious drawbacks, such as: 1. High weight; 2. High cost; 3. High resource consumption; 4. Poor recyclability; 5. Severe susceptibility to pests; 6. Unsuitable for precision packaging; 7. Relatively complex wood processing. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] This utility model provides a high-load-bearing and deformation-resistant all-paper heavy-duty packaging, comprising:

[0009] A paper pallet is placed at the bottom of the heavy packaging;

[0010] A box body, fixed on the paper pallet, is made of a first cardboard;

[0011] At least one pair of support plates, which are formed by stacking and fixing multiple layers of first cardboard, are respectively disposed on the inner side of the side wall in the short side direction of the box body;

[0012] At least one pair of reinforcing beams, which are formed by stacking and fixing multiple layers of first cardboard, are located on the bottom inner side of the side wall along the long side of the box and are connected to the cardboard pallet;

[0013] A top cover, made of a second cardboard, fits over the top opening of the box.

[0014] As a further embodiment of this utility model: the paper pallet includes a bottom box at the top and multiple pallet legs at the bottom. The bottom box is used to support and fix the box body, and the pallet legs are used to support the entire heavy packaging. A lower plate is provided between the bottom box and the pallet legs, and the two sides of the lower plate are respectively fixed to the bottom box and the pallet legs.

[0015] As a further embodiment of this utility model: an anti-bending plate is provided between the bottom box and the lower plate, which is made of a third cardboard, and the two sides of the anti-bending plate are respectively fixed to the bottom box and the lower plate.

[0016] As a further embodiment of this utility model: the upper cover is provided with a face cover and side strips, and the four side strips are connected end to end to form a frame and are fixed to the four sides of the face cover.

[0017] As a further embodiment of this utility model, it also includes at least one middle partition, which is vertically arranged between the support plates to divide the internal space of the box into at least two independent loading spaces.

[0018] As a further embodiment of this utility model, it also includes at least one pair of limiting structures, which are detachably disposed on the support plate to limit the displacement of the packaged goods.

[0019] As a further embodiment of this utility model: the first cardboard is made of corrugated cardboard with specifications of 3A1300 or 3C1200.

[0020] As a further embodiment of this utility model: the second cardboard is made of corrugated cardboard with specifications of 2C850 or BC850.

[0021] As a further embodiment of this utility model, the third cardboard is made of vertical honeycomb cardboard.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. The robust base box and stacked legs enhance the overall load-bearing capacity and provide stable support. The support plates and reinforcing beams are constructed using multi-layered cardboard, resulting in higher strength and compressive strength, effectively resisting deformation. The anti-bending plate between the base box and the lower panel further increases the overall structural stability, preventing deformation under heavy loads.

[0024] 2. The optional partition design allows for flexible partitioning of the internal space to meet the storage needs of various goods, while the equipped limiting structure effectively restricts the displacement of goods and improves safety.

[0025] Therefore, this utility model, through the ingenious design of the paper pallet, box body, support plate, reinforcing beam, top cover, and optional partitions and limiting structures, effectively improves the load-bearing capacity and deformation resistance of all-paper packaging. It not only meets the transportation needs of heavy goods but also makes a positive contribution to sustainable development.

[0035] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please see Figures 1 to 5 In this embodiment of the present invention, a high-load-bearing and deformation-resistant all-paper heavy-duty packaging includes: a paper pallet 10, disposed at the bottom of the heavy-duty packaging; a box body 20, fixed on the paper pallet 10, and composed of a first cardboard; at least one pair of support plates 30, composed of multiple layers of first cardboard stacked and fixed, respectively disposed on the inner side of the short side wall of the box body 20; at least one pair of reinforcing beams 40, composed of multiple layers of first cardboard stacked and fixed, disposed on the bottom inner side of the long side wall of the box body 20, and connected to the paper pallet 10; and a top cover 50, composed of a second cardboard, covering the top opening of the box body 20.

[0037] Specifically, the box body 20 is composed of four first cardboard sheets joined end to end, with the joints secured by internal nailing strips. The support plate 30 is made of four first cardboard sheets glued together, serving a supporting and pressure-resistant function. The three first cardboard sheets facing inwards from the box body 20 have corresponding limiting notches 32 at positions corresponding to the limiting structure 70, allowing the limiting structure 70 to be fixed to the support plate 30 by inserting into the limiting notches 32. The two first cardboard sheets facing inwards from the box body 20 have corresponding partition notches 33 at positions corresponding to the partition plate 60, allowing the partition plate 60 to be fixed to the support plate 30 through the partition notches 33.

[0038] Secondly, each reinforcing beam 40 is made of two 100mm high cardboard sheets and two 70mm high cardboard sheets bonded together, providing strong resistance to bending. Because the reinforcing beam 40 is made of cardboard of two different heights, it forms a high-low structure. This allows the higher outer cardboard to further improve the deformation resistance of the heavy-duty packaging, while the relatively lower inner cardboard does not occupy too much internal loading space in the box 20. To accommodate this high-low structure, serrated notches 34 can be provided on the support plate 30 at positions corresponding to the high-low structure. This allows for better connection between the support plate 30 and the reinforcing beam 40, further improving the load-bearing capacity of the heavy-duty packaging.

[0039] Furthermore, the first cardboard is made of corrugated cardboard with specifications of 3A1300 or 3C1200. The second cardboard is made of corrugated cardboard with specifications of 2C850 or BC850. The third cardboard is made of vertical honeycomb cardboard, which is a composite honeycomb board with a thickness of 25mm. It has single-layer cardboard on the top and bottom sides, and is filled with vertically distributed honeycomb cores with a side length of 4mm. The edges are reinforced with kraft paper for 20cm.

[0040] In addition, a first cardboard sheet facing the outside of the box 20 is provided with an adhesive hook and loop fastener 31. Similarly, on the inner side wall of the box 20, corresponding to the position of the adhesive hook and loop fastener 31 on the support plate 30, a corresponding adhesive hook and loop fastener 31 is also provided, so that the support plate 30 can be detachably fixed to the inner side wall of the box 20 by the adhesive hook and loop fastener 31.

[0041] like Figure 4 and Figure 5 As shown, preferably, the paper pallet 10 includes a bottom box 11 at the top and multiple pallet legs 13 at the bottom. The bottom box 11 is used to support and fix the box body 20, and the pallet legs 13 are used to support the entire heavy packaging. A lower plate 14 is provided between the bottom box 11 and the pallet legs 13, and the two sides of the lower plate 14 are respectively fixed to the bottom box 11 and the pallet legs 13. A bending-resistant plate 15 is also provided between the bottom box 11 and the lower plate 14, and the two sides of the bending-resistant plate 15 are respectively fixed to the bottom box 11 and the lower plate 14.

[0042] Specifically, the bottom box 11, like the top cover 50, is also made of a second cardboard. Adding a lower panel 14 between the bottom box 11 and the stacking feet 13 strengthens the connection between them, preventing damage to the bottom box 11 during transport. The lower panel 14 is composed of at least one layer of second cardboard.

[0043] Secondly, adding a bending-resistant plate 15 between the bottom box 11 and the lower plate 14 can enhance the overall bending resistance of the paper pallet 10. The bending-resistant plate 15 is composed of at least one layer of third cardboard. The pallet legs 13 are filled with heavy materials as filler and wrapped and glued with a second cardboard on the outside.

[0044] The heavy-duty material can be made from recycled paper pulp blocks, which are then glued together and processed using a saw. Recycled paper pulp blocks are made by reprocessing waste paper into pulp, pressing it through molds, drying it, and shaping it into blocks. Firstly, it is inexpensive, aligning with the low-cost characteristics of paper pallets 10; secondly, it can be molded into shapes and weights as needed, making it practical for filling paper pallet legs 13, increasing self-weight, and enhancing pressure resistance. It also facilitates the reuse of waste paper, aligning with environmental protection principles.

[0045] Furthermore, the four sides of the bottom box 11 are each provided with convex sidewalls 12 that protrude upwards to a certain height, so that when the box body 20 is fixedly connected to the bottom box 11, the outer sidewall of the box body 20 can be fixedly connected to the inner side of the convex sidewall 12 of the bottom box 11. The convex sidewall 12 of the bottom box 11 and the bottom surface of the bottom box 11 can be connected using a nail strip connection process. In addition, L-shaped paper corner protectors 16 can be provided at the edges of the lower plate 14 and the anti-bending plate 15 of the paper pallet 10, respectively, for bonding and fixing, providing a certain degree of reinforcement and protection.

[0046] like Figure 5 As shown, preferably, the upper cover 50 is provided with a face cover 51 and four side strips 52. The four side strips 52 are connected end to end to form a frame and are fixed to the four sides of the face cover 51.

[0047] Specifically, the connection between the two sides of the edge strip 52 is set in an L-shape, so that one side is fixed to the cover 51 and the other side can be fastened to the outer wall of the box 20, so that the top cover 50 can be closed to the top opening of the box 20.

[0048] like Figure 2 and Figure 5 As shown, preferably, it also includes at least one partition 60, vertically disposed between the support plates 30, dividing the internal space of the box 20 into at least two independent loading spaces. The partition 60 is formed by stacking and fixing multiple layers of first cardboard. Specifically, the partition 60 is made from a single sheet of first cardboard, and the partition 60 can be inserted into and fixed to the support plate 30 through the partition notch 33 on the support plate 30.

[0049] like Figure 2 and Figure 5As shown, preferably, it also includes at least one pair of limiting structures 70, which are detachably disposed on the support plate 30 and are provided with at least one limiting hole 71 for limiting the displacement of the packaged goods. The limiting structure 70 is formed by stacking and fixing multiple layers of first cardboard.

[0050] Specifically, the limiting structure 70 is made of three layers of first cardboard bonded together. The upper part of the support plate 30 is provided with a U-shaped or V-shaped limiting notch 32, and the limiting structure 70 is set with a corresponding U-shape or V-shape, so that it can be inserted into the corresponding limiting notch 32, and a certain limiting space is formed between the limiting structure 70 and the support plate 30, so as to limit the packaged goods and prevent them from moving during transportation.

[0051] Secondly, additional limiting holes 71 can be provided on the limiting structure 70 to restrict the corresponding parts of the packaged goods and prevent them from moving.

[0052] In addition, the outer surfaces of the box body 20, top cover 50, support plate 30, reinforcing beam 40, and paper pallet 10 are all covered with reinforcing paper. Preferably, the paper is 440g kraft paper. To further enhance its structural strength, the outer perimeter of the heavy-duty packaging can also be secured with plastic-coated steel strapping.

[0053] Example 1, standard configuration. This example is used for packaging 1 ton of aluminum foil rolls and mainly includes core components 1-5:

[0054] Paper pallet 10: The bottom adopts a three-layer structure: the top layer is the bottom box 11, which is connected to the box body 20; the middle layer is the anti-bending board 15, which enhances the bending resistance; and the bottom layer is the lower plate 14, which provides basic load-bearing. The pallet legs 13 are made of corrugated cardboard to ensure stable loading and unloading by forklift. For example, the following configuration can be adopted: bottom layer: lower plate 14 (2mm thick) made of a second layer of cardboard; middle layer: anti-bending board 15 (25mm thick) made of a third layer of cardboard; top layer: bottom box 11 (2mm thick) made of a second layer of cardboard; pallet legs 13: corrugated cardboard glued together to enhance the support strength.

[0055] Box 20: Made of first-grade cardboard with an edge pressure exceeding 260 N / m, forming the four side walls of the packaging, with a thickness of 3-4 mm.

[0056] Support plate 30: Located on the inner side of the short side of the box 20, it is made of multiple layers of first cardboard bonded together to enhance the pressure resistance of the box 20. Number of bonding layers: 3-4 layers.

[0057] Reinforcing beam 40: Located on the bottom inner side of the long side of the box 20 (where the side wall meets the bottom box 11), it is also made of multiple layers of first cardboard bonded together, with 3-4 layers, to enhance bending resistance and prevent the box 20 from deforming under heavy pressure.

[0058] Top cover 50: Made of a second cardboard of the same material as the bottom cover, with a thickness of 2mm, to ensure the top is resistant to pressure and the integrity of the overall structure.

[0059] Partition 60 (optional): In this embodiment, partition 60 may not be used because 1 ton of aluminum foil roll does not require separation.

[0060] Limiting structure 70 (optional): In this embodiment, the limiting structure 70 may not be used because the aluminum foil roll itself has a stable structure.

[0061] After loading, the heavy-duty packaging passed the simulation test. Under a load of 1 ton, the heavy-duty packaging achieved a bending strength of 3 tons and a compressive strength exceeding the peak value of 5 tons, and the heavy-duty packaging remained intact.

[0062] Example 2: Reinforced Configuration. This example is used for packaging a 2-ton lithium battery module, including core components 1-5 and optional component 6.

[0063] All components are the same as in Embodiment 1, but thicker and stronger corrugated cardboard is required. For example, the following adjustments are made: the cardboard thickness is increased by 20%, an additional layer of adhesive is added to the support plate 30 and reinforcing beam 40, and a partition plate 60 (component 6) is added. The partition plate 60 is placed vertically between the two support plates 30, dividing the internal space into two parts, enhancing bending and compression resistance, and improving safety to prevent damage to the module during transportation. The limiting structure 70 (component 7) can be customized according to the specific dimensions and structure of the lithium battery module to ensure the module is securely fixed during transportation.

[0064] The test showed that the heavy-duty packaging, after being loaded, could maintain its structural integrity and had no risk of deformation under a load of 2 tons.

[0065] Example 3: Overweight Configuration. This example is used to package a 2.5-ton large casting, comprising all seven components:

[0066] All components are the same as in Example 2, but the thickness and strength of all cardboard need to be further improved. Thicker and stronger corrugated cardboard should be used, for example, increasing the cardboard thickness by 30% and increasing the number of adhesive layers to 5-6 layers to withstand enormous pressure and stress. Due to the huge weight load, the partition 60 (component 6) and the limiting structure 70 (component 7) are essential. The partition 60 can be adjusted according to the shape and size of the casting to effectively distribute the weight and prevent deformation. For example, a double-layer partition 60 can be added, the limiting structure 70 can be made more precise, and an external shock-absorbing pad layer can be added. The limiting structure 70 needs to be specially designed to ensure that the large casting does not move or tilt during transportation. In addition, it is possible to consider adding a protective layer to the outer perimeter of the packaging, such as thickened kraft paper or other suitable materials, and adding shock-absorbing materials to prevent external impacts.

[0067] The test showed that the heavy-duty packaging, after being loaded, could still maintain its integrity under a load of 2.5 tons, and its bending and compressive strength met the expected requirements.

[0068] All embodiments require the use of plastic strapping to secure the packaging after completion, further enhancing the overall strength and stability of the packaging. The selection and thickness of all cardboard materials must be adjusted based on the actual load and product characteristics.

[0069] These embodiments demonstrate the flexibility of this patented technology under different load capacities and product types. By adjusting the number of components, material thickness, and structural design, it is possible to meet the needs of various high-load-bearing all-paper packaging, achieving a perfect combination of environmentally friendly and high-strength packaging.

[0070] This utility model is a heavy-duty packaging product, mainly used for packaging and transporting products with high load capacity (1~2.5 tons), high environmental protection requirements, and requiring the use of all-paper packaging, such as aluminum foil rolls in the new energy and new materials industries.

[0071] This heavy-duty package consists of seven parts in total, with parts 1 through 5 being the core components. Parts 6 and 7 are optional further enhancements. Details are as follows:

[0072] 1. Paper Pallet 10: Located at the bottom of the heavy-duty packaging, it supports the entire heavy-duty packaging, facilitating loading and transportation using a forklift. A bottom box 11 is located at the top of the paper pallet 10, with a bending-resistant plate 15 attached to the bottom of the bottom box 11, and a lower mounting plate 14 attached to the bottom of the bending-resistant plate 15. The pallet legs 13 are made of corrugated cardboard. The entire paper pallet 10 has a reasonable structure, better bending resistance, and is more robust and secure.

[0073] 2. Box 20: Fixed above the bottom box 11, it is assembled to form the four side walls of heavy-duty packaging. It uses first cardboard with an edge compression of more than 260 N / m, and has high compressive and bending strength.

[0074] 3. Support plate 30: It is formed by bonding and pressing multiple layers of first cardboard together, and is set on the inner side of the two side walls in the short side direction of the carton 20 to enhance the carton's compression resistance.

[0075] 4. Reinforcing beam 40: It is formed by bonding and pressing multiple layers of first cardboard together. It is set at the bottom of the inner side of the two side walls along the long side of the box body 20, that is, at the angle where the side wall intersects with the bottom box 11. It mainly strengthens the bending resistance of heavy packaging.

[0076] 5. Top cover 50: Covers the opening at the top of the box 20. The main material used is second cardboard, which gives it a certain degree of pressure resistance.

[0077] 6. Divider 60: Vertically positioned between the two support plates 30, it divides the internal space of the heavy-duty packaging into two loading spaces along its long side. It serves three purposes: first, it increases the overall bending strength of the packaging; second, it increases the packaging's compressive strength; and third, it isolates and protects the product.

[0078] 7. Limiting structure 70: Inserted into the pre-set notch at the top of the support plate 30, used to restrict the position of the product loaded inside the heavy packaging. Limiting structures 70 are respectively set on the support plates 30 on both sides of the box body 20, and limiting holes 71 are set on the limiting structures 70, so that the handles or crossbars of the loaded products can be inserted into the limiting holes 71 to form a limiting effect.

[0079] In addition, to improve aesthetics, a linerboard made of 440g kraft paper can be applied to the surface of the heavy-duty packaging. After the products to be packaged are loaded, the entire heavy-duty packaging is secured with plastic strapping around its perimeter, forming a unified whole with strong resistance to bending and compression.

[0080] This heavy-duty packaging uses a structure that enhances the packaging's resistance to bending. In addition, high-strength corrugated cardboard is used on the support plate 30 and the reinforcing beam 40, and honeycomb panels are installed on the paper pallet 10, which further improves the overall bending resistance.

[0081] Through simulation experiments, the bending resistance reached 3 tons; the packaging pressure resistance reached a peak of 5 tons, and the packaging remained intact; through actual use, the packaging remained intact on site, and the quality was reliable.

[0082] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
