Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, and in particular to a foldable collapsible box. Background Technology

[0002] Collapsible pallets (also known as palletized crates) are widely used in the logistics industry, playing a crucial role in protecting and facilitating goods during storage and transportation. Typically made of materials such as wood, steel, or plastic, collapsible pallets are primarily used for storing and transporting bulk goods and offer high reusability. Beyond traditional cargo transportation and warehousing, collapsible pallets are increasingly expanding into emerging fields such as cross-border e-commerce and cold chain logistics. Their robust structure and flexible usage meet the needs of diverse industries.

[0003] Collapsible palletized crates are increasingly favored by the logistics and warehousing industries due to their unique foldable design and efficient space utilization. Collapsible palletized crates are characterized by their lightweight structure, easy disassembly, and convenient storage and transportation, and have been widely used in various fields. They are very convenient in logistics transportation; they can be folded during transport, reducing the space occupied by empty crates and thus lowering transportation costs. After transporting goods, the crates can be folded back into a compact shape, facilitating recycling and reuse, and improving logistics efficiency. Currently, most collapsible palletized crates use either a one-piece folding body or a four-sided panel splicing body, both of which have their limitations.

[0004] Integrated folding cases rely on hinges or pre-compression creases for folding. Repeated opening and closing can easily lead to material fatigue (such as cracking at plastic creases or deformation of metal hinges), especially the flexible creases located in the middle of the case panels, which can significantly reduce the load-bearing capacity of the case. Localized damage (such as cracked creases or detached hinges) often requires replacement of the entire case, as individual components cannot be repaired, resulting in high long-term costs. Although the volume is reduced after folding, due to the integrated design, some cases still have a certain thickness after folding, and the space occupied when transporting empty cases is still greater than that of completely disassembled modular cases.

[0005] The four-sided panel assembly design requires manual alignment and securing of multiple components (such as side panels, bottom panels, and clips), making the process cumbersome and highly dependent on manpower, unsuitable for high-frequency, fast-paced logistics scenarios. The multi-component design increases the risk of loss (e.g., small parts like pins and clips), and the low standardization of components from different manufacturers makes replacement difficult after damage, leading to maintenance challenges. While disassembled components can be transported flat, the need for categorized packaging increases management complexity, and components are prone to scattering during transport, increasing loading / unloading time and labor costs.

[0006] Therefore, how to design a low-cost, high-recyclability, high-structural-stability, and easy-to-use foldable collapsible box is an urgent problem to be solved. Summary of the Utility Model

[0007] In view of this, embodiments of the present utility model provide a folding pallet box to eliminate or improve one or more defects existing in the prior art.

[0008] A folding pallet box includes a bottom cover, two foldable side panels and a top cover; wherein, the foldable side panel includes a side plate and two half plates oppositely arranged on both sides of the side plate, and the half plates are connected to the side plate through a foldable structure, so that the foldable side panel can be folded into a plate-like structure and can also be unfolded into a "C" - shaped structure; a connecting structure is further provided on the side of the half plate of the foldable side panel away from the side plate for fixedly connecting the two foldable side panels in the state where the two foldable side panels enclose a square box body; the bottom cover and the top cover are used to be arranged at the bottom and top of the square box body to enclose a closed box body.

[0009] In some embodiments, the connecting structure includes at least one loop side of a magic tape provided on one foldable side panel and a hook side of a magic tape provided on the other foldable side panel; when the connecting structure includes more than two magic tapes, each magic tape is arranged at a different height position.

[0010] In some embodiments, a limiting structure is provided at the end of the half plate of the foldable side panel away from the side plate. The limiting structure includes a socket provided at the end of the half plate of one foldable side panel and a plug strip provided at the end of the half plate of the other foldable side panel, and the plug strip matches the socket; alternatively, the limiting structure includes an H - shaped connecting piece, and the thickness of the two side grooves thereof matches the thickness of the end of the half plate of the foldable side panel.

[0011] Reinforcing members arranged horizontally and / or vertically are provided on the side plate and / or the half plate structure of the foldable side panel.

[0012] In some embodiments, corresponding slot structures are provided at the positions of the bottom cover and the top cover corresponding to the bottom and top of the foldable side panel, so that the foldable side panel can be inserted into the slot structures for combination.

[0013] In some embodiments, the bottom cover and the top cover have the same structure and are interchangeable; both the bottom cover and the top cover include a square cover body. Two L - shaped protrusions are provided at the first diagonal part of the square cover body, and two corresponding L - shaped recesses are provided at the second diagonal part of the square cover body. Limiting protrusions are provided on both sides of the L - shaped recess; in the state where the pallet boxes are stacked, the first diagonal part of one square cover body is used to dock with the second diagonal part of another square cover body to form a reverse buckle.

[0014] In some embodiments, the outer surfaces and sides of the bottom cover and the top cover are provided with a plurality of corresponding steel-plastic belt limiting grooves; and / or, the inner surfaces of the bottom cover and the top cover are provided with a plurality of weight-reducing holes.

[0015] In some embodiments, the side panels and half panels of the foldable enclosure are made of integrally extruded PP material.

[0016] In some embodiments, the system further includes a tray, which includes a top support plate, a bottom support plate, and a plurality of support columns disposed between the top support plate and the bottom support plate, wherein toothed holes are formed between the support columns.

[0017] In some embodiments, the dimensions of the square box formed by the foldable panels are designed to be 1100×1100×840mm, and its internal loading dimensions are designed to be 1072×1072×800mm; the dimensions of the top cover and bottom cover are designed to be 1147×1147×55mm; and the dimensions of the tray are designed to be 1100×1100×150mm.

[0018] This utility model's folding collapsible box employs an innovative folding design. It can be assembled from two "U"-shaped foldable collapsible panels to form a box or folded into a panel shape. After recycling, its volume is significantly reduced compared to existing folding collapsible boxes, facilitating storage and transportation. Each collapsible panel's half-panel is connected to the side panel via a foldable structure. Assembly is simple: just unfold the half-panel and secure it with the connecting structure. Disassembly is also easy and quick. This design avoids traditional complex operations or the need for tools, reducing operational difficulty and improving efficiency. The bottom and top cover design ensures the box's sealing and stability, reducing collisions or compression during transportation and thus lowering the risk of damage. Furthermore, because the collapsible panels are designed to withstand significant forces, the folding collapsible box is durable, reducing replacement frequency and extending its service life. Due to its robust structure and ease of folding for storage, this folding collapsible box can be used multiple times, reducing costs associated with frequent replacements due to damage or aging. Simultaneously, it reduces storage space and transportation costs, saving resources for businesses.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0031] Here, it should also be noted that in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution according to the present utility model are shown in the drawings, while other details less related to the present utility model are omitted.

[0033] Here, it should also be noted that if there is no special indication, the term "connection" in this article can not only refer to direct connection, but also represent indirect connection with an intermediate object.

[0034] In the following, embodiments of the present utility model will be described with reference to the drawings. In the drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0035] In view of various problems existing in the integral folding box body and the four-sided box board splicing box body in the prior art, the embodiments of the present utility model provide an innovative designed folding panel box, which can be used as a special panel box or a standard panel box. Through structural innovation and material optimization, the present utility model has made breakthroughs in aspects such as logistics efficiency, life cycle cost and environmental compatibility, and is particularly suitable for scenarios such as high-turnover cross-border e-commerce, automotive parts logistics and cold chain transportation, representing the forefront design direction in the field of folding panel boxes.

[0036] In some embodiments, the present utility model provides a folding panel box, as Figures 1-4 shown, which includes a bottom cover 1b, two foldable panels 2 and a top cover 1a. Among them, the foldable panel 2 includes a side panel 21 and two half panels 22 oppositely arranged on both sides of the side panel 21. The half panel 22 is connected to the side panel 21 through a foldable structure, so that the foldable panel 2 can be folded into a plate-like structure and can also be unfolded into a "匚"-shaped structure. The structure of the half panel 22 here, that is, the two half panels 22 on the docking sides of the two foldable panels 2 can enclose a complete side box board, such as each length can account for 50%, but not limited to this, such as 40% and 60%, etc. The foldable structure described here can be folded using hinges or pre-pressed creases in the prior art, such as using prefabricated creases of the same material as the box body, and realizing the foldable design through material improvement or thickness reduction.

[0037] As Figure 1 and Figure 3As shown, a connecting structure 23 is provided on the side of the half-panel 22 of the foldable enclosure 2 away from the side panel 21, which is used to fix the two foldable enclosures 2 together when they are enclosed in a square box; the bottom cover 1b and the top cover 1a are provided at the bottom and top of the square box to form a closed box.

[0038] Compared to traditional one-piece folding boxes, pre-fabricated creases are prone to localized stress concentration during repeated folding, leading to material fatigue cracking. The folding panel box in this embodiment eliminates the pre-fabricated creases in the middle of the panel and employs a highly reliable connection structure 23, ensuring uniform stress distribution across the panel, significantly improving bending strength, folding life, strength, and load-bearing capacity. To achieve the same standard load capacity, the panel thickness used in the folding panel box in this embodiment is less than that of a one-piece folding box. Furthermore, because the creases in the middle of the panel are eliminated, the folded space is flatter, with less sidewall deformation and a higher recycling rate.

[0039] Compared to traditional four-sided panel assembly boxes, which require manual alignment and fixing of four panels (taking 3-5 minutes), this invention only requires unfolding two "U"-shaped panels and locking the connecting structure 23 (such as Velcro, magnetic snaps, or tenon and mortise fasteners), allowing assembly to be completed in one minute without the need for tools. Small accessories (such as bolts and pins) in traditional assembly boxes are easily lost, while this invention adopts a component-free design, consisting only of a bottom cover 1b, a top cover 1a, and two folding panels, significantly reducing the number of parts and greatly simplifying warehousing and transportation management. The assembly and folding process is simple and requires no special training to use.

[0040] In existing palletized box designs, if a dedicated base plate is not integrated and external pallets 3 or universal bases are used instead, there are indeed significant shortcomings in terms of sealing, structural stability, and functional adaptability. The pallets and universal pallets 3 are only connected by simple snap-fits or gravity pressing, which cannot form a tight seal, allowing liquids (such as cold chain condensate) or dust to easily seep in through the gaps. Furthermore, the lack of a locking mechanism between the pallets and pallets 3 means that the upper box may slide during stacking, causing goods to tip over. The foldable palletized box in this embodiment of the invention not only has a top cover 1a but also a bottom cover 1b. Through the sealing design of bottom cover 1b—pallets—top cover 1a, it not only solves the sealing and structural defects of traditional bottomless palletized boxes but also achieves breakthroughs in circular economy and scenario adaptability, providing a packaging solution for high-value, high-requirement logistics scenarios.

[0041] In some embodiments, the connecting structure 23 of the folding collapsible box of this utility model can flexibly select connection methods such as Velcro, magnetic snaps, or elastic buckles, but the performance differences need to be weighed according to the specific needs of the scenario. Velcro has the advantages of low cost, lightweight and simple operation, magnetic snaps have the advantages of fast adsorption, no mechanical wear and repeatable positioning, and elastic buckles have the advantages of high locking force and good sealing performance. The connection method can be selected comprehensively according to load requirements, environmental severity, operation frequency and cost budget, and can also be combined to achieve a balance between performance and economy.

[0042] As at least one possible way, such as Figure 1 and Figure 3 As shown, the connecting structure 23 includes at least one hook-and-loop fastener on the rough surface of one foldable panel 2 and a hook-and-loop fastener on the hook surface of another foldable panel 2. When the connecting structure 23 includes two or more hook-and-loop fasteners, each fastener is positioned at a different height. For example, a nylon rough-loop fastener strip can be horizontally positioned along the edge of one panel, and a high-density hook-and-loop fastener strip can be matched to the other panel, forming a horizontal overlapping closure. Two to five hook-and-loop fasteners are spaced apart along the height of the panels, and layered, staggered bonding enhances shear resistance. The tensile force borne by each hook-and-loop fastener is evenly distributed through the height difference, avoiding stress concentration at a single point. The fiber structure of the hook-and-loop fastener rough surface can adapt to slight deformation, maintaining a long-term sealing effect.

[0043] Compared to existing one-piece folding boxes, which are prone to cracking at low temperatures due to the high stress on the central fold structure (e.g., the risk of PP plastic folds breaking increases at -20°C), the folding collapsible box in this embodiment eliminates the pre-fabricated folds in the center of the box panel and adopts a highly reliable Velcro structure. Combined with improvements in the materials and processes of the foldable collapsible panel 2, it can withstand temperatures as low as -30°C, making it suitable for the pharmaceutical cold chain transportation industry. Through structural innovation and a full life-cycle design approach, this invention surpasses traditional modular boxes in terms of logistics efficiency, operational friendliness, and environmental compatibility. It is particularly suitable for high-value, high-turnover, and environmentally demanding global logistics scenarios, representing the technological evolution direction of collapsible boxes.

[0044] In some embodiments, a limiting structure is provided at the end of the half-plate 22 of the foldable enclosure 2 away from the side plate 21. This limiting structure can achieve precise positioning and shear resistance reinforcement of the enclosure by mechanical interlocking. Optionally, the limiting structure includes an insertion groove provided at the end of the half-plate 22 of one foldable enclosure 2, and an insertion strip provided at the end of the half-plate 22 of the other foldable enclosure 2, the insertion strip matching the insertion groove. Further, the cross-section of the insertion groove is H-shaped, with guide bevels on the left and right wings (e.g., inclination angle 15°-20°), and a central recess forming a locking area (e.g., depth can be designed to be 3-5mm). The groove width and the tolerance for matching the insertion strip can be designed to be ±0.2mm. The cross-section of the insertion strip can be designed as an inverted trapezoidal protrusion, which can be smoothly inserted into the insertion groove.

[0045] As another possible approach, such as Figure 4 As shown, the limiting structure includes an H-shaped connector 24, the thickness of which is matched with the thickness of the end of the half-plate 22 of the foldable enclosure 2. The two slots of the H-shaped connector 24 can be interchanged, or one of the slots can be configured as an interference fit (clamping side) with a large clamping force on the half-plate, while the other slot (disassembly side) can be configured as a clearance fit with the half-plate for easy disassembly and assembly, so as to facilitate folding and disassembly operations.

[0046] In the above embodiments, the Velcro connection structure 23 has a certain degree of elasticity, which can effectively disperse external impact forces under violent operation. For example, during transportation, the box may be impacted or subjected to sudden compression. The Velcro can absorb the impact force through its adhesive and elastic properties, reducing damage to the box and ensuring the stability of the box structure. The interlocking slot, as a limiting structure, can effectively limit the displacement or deformation of the side panel. When external force is applied, the interlocking slot will play a role in stabilizing the positioning, preventing the side panel from accidentally loosening or deforming. In this way, even if subjected to violent operation, the overall shape and structure of the box will not be easily affected. The Velcro connection method is very simple, requiring no complicated tools or high-skill operation. The operator only needs to align the two sides of the Velcro and press them together to complete the connection, and to disassemble, simply pull them apart. This simple operation method reduces the requirements for operators, allowing anyone without specialized training to complete the task quickly. The design of the interlocking slot allows the side panel to be firmly inserted into the slot, avoiding the need for additional adjustments or precise operations. Even in high-intensity use environments, personnel do not need to spend a lot of effort to ensure structural stability. Hook and loop fasteners are inherently durable, capable of withstanding repeated stretching and bonding. Compared to traditional metal connectors, hook and loop fasteners wear and age more slowly, and are less prone to damage from frequent disassembly and rough handling. Compared to traditional metal connectors or plastic fasteners, hook and loop fasteners offer better fatigue resistance. Even under frequent use or high-intensity operation, they maintain strong adhesion and are not easily damaged or lose their stickiness. This durable connection significantly extends the lifespan of the case. Even after prolonged use and failure, hook and loop fasteners are relatively easy to replace.

[0047] In some embodiments, the side panels 21 and / or half-panels 22 of the foldable enclosure 2 are provided with transversely and / or longitudinally arranged reinforcements to improve the overall performance of the enclosure through mechanical optimization. This design effectively balances folding flexibility, load-bearing capacity, and durability through structural reinforcement. The reinforcements can resist bending deformation of the enclosure during stacking and transportation (such as forklift impacts or eccentric loads). The reinforcements can also reduce stress concentration at folding creases, hinges, or connections, extending the structural lifespan. The reinforcements achieve maximum strength improvement with minimal material increment through topology optimization. The reinforcements can be made of metal materials such as aluminum alloys, or lightweight, high-strength materials such as carbon fiber.

[0048] Different types of reinforcements serve different purposes. Lateral reinforcements can resist lateral impacts (such as forklift collisions), while longitudinal reinforcements can improve vertical compressive strength (such as stacking loads). Reinforcements can also be configured as diagonally intersecting or in a honeycomb grid pattern. Diagonally intersecting reinforcements can resist combined loads (such as combined ocean turbulence and stacking pressure), while honeycomb grid reinforcements enable lightweight designs with high rigidity. By scientifically arranging lateral / longitudinal reinforcements, the collapsible box achieves an optimal balance between lightweight, strength, and durability. This design is particularly suitable for high-value-added, high-turnover logistics scenarios, providing the industry with a structured solution that balances performance and cost.

[0049] In some embodiments, such as Figure 4 As shown, the bottom cover 1b and top cover 1a are provided with corresponding slot structures 11 at the bottom and top positions of the foldable enclosure 2, respectively, so that the foldable enclosure 2 can be inserted into the slot structure 11 for assembly, achieving quick insertion, ensuring sealing and structural stability. As at least one possible implementation, the width of the slot corresponds to the thickness of the top and bottom edges of the enclosure, and both can be designed with guide slopes or matched with a reasonable slot depth design. After the foldable enclosure is inserted into the slot structure 11, its two sides form a door-like contact with the side wall of the slot, which can increase the shear strength and also increase the sealing of the box, preventing the goods from being contaminated during transportation.

[0050] In some embodiments, the bottom cover 1b and the top cover 1a have identical structures and are interchangeable; this reduces the need for manufacturing and inventorying different components during production. Only covers of uniform specifications need to be produced, simplifying the production process and reducing costs. In practical applications, such as during transport and assembly, there is no need for special classification and placement of the bottom cover 1b and the top cover 1a, making them convenient to use. If a cover is damaged or lost, it can be directly replaced without special matching or additional parts, making maintenance simpler.

[0051] As at least one possible way, such as Figure 3As shown, both the bottom cover 1b and the top cover 1a include square covers. Each square cover has two L-shaped protrusions 121 at its first diagonal and two corresponding L-shaped recesses 122 at its second diagonal. Each L-shaped recess 122 has limiting protrusions 123 on both sides. When the pallet boxes are stacked, the first diagonal of one square cover is used to engage with the second diagonal of the other square cover to form a snap-fit. This snap-fit ​​design ensures a tight fit during stacking, preventing slippage or loosening. The snap-fit ​​structure ensures the stability of the pallet boxes during stacking, preventing collapse due to instability even during transportation or storage. The snap-fit ​​structure also distributes the weight applied during stacking more evenly, preventing excessive pressure on any single part and improving the safety and durability of the entire stacking structure. Because the mating structure of the covers is standardized (through L-shaped protrusions and recesses), assembly errors are less likely to occur, improving operational accuracy. The L-shaped protrusions and recesses allow for a tighter fit between the bottom cover 1b and the top cover 1a, enhancing the container's airtightness. This is especially important for applications requiring the safekeeping of goods, such as preventing the intrusion of dust, moisture, or external contaminants. The interchangeable lids and robust snap-fit ​​structure allow multiple collapsible containers to be stacked tightly, reducing space requirements and thus lowering transportation and storage costs.

[0052] In some embodiments, such as Figure 3 As shown, several corresponding steel-plastic tape limiting grooves 13 are provided on the outer surface and sides of the bottom cover 1b and the top cover 1a. The steel-plastic tape, as a material to enhance structural strength, combined with the limiting groove design, can prevent the box from deforming or sliding under external force during stacking. The limiting grooves effectively fix the relative position of the steel-plastic tape, increasing the stability of the cover and making it less prone to displacement during transportation, stacking, and use. By combining the steel-plastic tape with the limiting grooves, the pressure on the cover can be distributed, preventing excessive pressure on certain areas, thereby improving the overall pressure resistance. The design of the steel-plastic tape limiting grooves 13 helps ensure a more secure connection between the bottom cover 1b and the top cover 1a, avoiding the risk of the cover falling off during transportation or operation. Especially when subjected to greater pressure or external force, the limiting grooves can effectively fix the position of the steel-plastic tape, enhancing the safety of the overall structure. The limiting groove design allows for more precise positioning of the steel-plastic tape, simplifying the assembly process. The steel-plastic tape can be quickly and accurately fixed in the limiting grooves, reducing the complexity of manual operations and improving assembly efficiency.

[0053] In some embodiments, such as Figure 4As shown, the inner surfaces of the bottom cover 1b and the top cover 1a are provided with a plurality of weight-reducing holes 14. This design can optimize the overall performance of the product by reducing the weight of the components. Optionally, by providing honeycomb-shaped weight-reducing holes 14 on the inner surfaces of the bottom cover 1b and the top cover 1a, the amount of material used can be effectively reduced, thereby reducing the overall weight of the component. The honeycomb structure can still provide high strength and rigidity while maintaining lightweight. This is because the layout of the honeycomb holes can effectively disperse the externally applied pressure, enhancing the compressive strength of the bottom cover 1b and the top cover 1a. Even with the reduction of some materials, this structure can still ensure the overall load-bearing capacity. Lightweight design helps to reduce the costs and energy consumption caused by excessive weight during transportation. Especially in the large-scale logistics and transportation industry, lightweight packaging can significantly reduce transportation costs. The honeycomb structure has a certain degree of thermal insulation function, which can reduce heat conduction and improve the performance of equipment in high-temperature environments.

[0054] In some embodiments, the side panels 21 and half panels 22 of the foldable panel 2 are made of integrally extruded PP material. PP (polypropylene) material has better impact toughness and crack resistance at low temperatures compared to HDPE (high-density polyethylene); PP material also has better processability in extrusion processes. Compared to the thermoforming process of HDPE, PP extrusion can more easily achieve complex shapes and structural designs, and the thickness and size of the sheet can be adjusted using different molds to meet more precise production requirements. HDPE is prone to deformation at high temperatures; in contrast, PP has a higher heat distortion temperature, making it more stable at high temperatures and avoiding softening and deformation problems that may occur at high temperatures. PP material has a lower density than HDPE, therefore, panels made using PP extrusion are lighter overall than panels made using HDPE thermoforming, making them easier to transport and handle. PP has better corrosion resistance to most chemicals, such as acids, alkalis, and solvents. Therefore, panels made of PP can better resist chemical corrosion when used in harsh environments, extending their service life. HDPE thermoforming typically requires higher energy consumption, and its recycling and reuse efficiency is relatively low. In contrast, PP material has a higher recycling value and can be recycled and reused at lower temperatures. HDPE thermoforming usually requires more time for molding and cooling, resulting in relatively lower production efficiency. In contrast, PP extrusion can achieve higher production efficiency. Through a continuous extrusion process, large quantities of panels can be produced quickly, reducing production cycles and lowering costs.

[0055] In some embodiments, such as Figure 1As shown, it also includes a pallet 3, which comprises a top support plate 31, a bottom support plate 33, and several support columns 32 disposed between the top support plate 31 and the bottom support plate 33. Insertion holes 34 are formed between the support columns 32. Through the combined design of the top support plate 31, bottom support plate 33, support columns 32, and insertion holes 34, the pallet 3 has higher stability, convenient assembly and disassembly, stronger load-bearing capacity, and optimized material utilization, making it suitable for various industrial and logistics applications. This foldable collapsible box uses the pallet 3 as its base; it can be used by simply placing the box on the pallet 3. Of course, the pallet 3 can also be used independently.

[0056] During installation, assemble the tray 3, bottom cover 1b, foldable side panel 2 and top cover 1a together according to the following steps: 1. Place the tray 3: Place the tray 3 on the ground, ensuring the stability and levelness of the tray 3.

[0057] 2. Install bottom cover 1b: Place bottom cover 1b on tray 3 first, ensuring that bottom cover 1b completely covers the bottom of tray 3 to provide support and protection.

[0058] 3. Install the foldable enclosure 2: Place a foldable enclosure 2 on the bottom cover 1b, ensuring that the enclosure fits tightly with the bottom cover 1b on all sides to form an enclosure structure.

[0059] 4. Place the second foldable panel 2: Place the second foldable panel 2 on the tray 3, ensuring that the panel forms a closed boundary structure with the first panel. Use Velcro to secure the two foldable panels 2 together, ensuring they are firmly connected and preventing displacement during use.

[0060] 5. Cover with top cover 1a: Place top cover 1a on top of the enclosure panel, ensuring that top cover 1a covers the enclosure panel to form a closed overall structure.

[0061] 6. Use packing straps / steel-plastic straps to pack: Use packing straps to secure the entire pallet 3, bottom cover 1b, two foldable side panels 2 and top cover 1a together to ensure that the entire assembly structure is tight and stable, making it easy to handle and store.

[0062] Through this assembly method, the pallet 3 is tightly integrated with the foldable side panels 2 and the top cover 1a, forming a stable and reliable packaging structure suitable for transportation and storage. The use of Velcro facilitates quick assembly and disassembly, while the application of packing straps ensures the overall structural integrity.

[0063] In some embodiments, the dimensions of the square box formed by the foldable collapsible panels 2 are designed to be 1100×1100×840mm, and its internal loading dimensions are designed to be 1072×1072×800mm; the dimensions of the top cover 1a and bottom cover 1b are designed to be 1147×1147×55mm; and the dimensions of the pallet 3 are designed to be 1100×1100×150mm. This dimensional design allows the foldable collapsible box in this embodiment of the invention to comply with some international standards, making it compatible with other international transport equipment and facilitating cross-border transportation and storage. This dimensional design ensures that the foldable collapsible box can effectively utilize container space. For example, standard containers (such as 20-foot or 40-foot containers) can accommodate more units of foldable collapsible boxes, maximizing transportation efficiency and reducing transportation costs. The standardized dimensions and easy-to-fold design make the foldable collapsible box more widely used globally. Whether in warehousing, transportation, or distribution, the standardized dimensions make it compatible with logistics facilities, transport vehicles, and storage equipment around the world.

[0064] The load-bearing capacity of existing four-sided panel-assembled boxes is significantly higher than that of integrated folding boxes, which can roughly support a load of 350kg. However, the folding panel box in this embodiment of the utility model has a significantly improved load-bearing capacity, designed to support a dynamic load of 1000kg and a static load of 3000kg. This is a clear advantage over traditional panel-assembled boxes.

[0065] The foldable collapsible box in this embodiment of the invention has a retractable body of only 0.16m. 3 Even with a tray, it's only 0.36m. 3 The container recycling ratio can reach 1:7, and the volume of the folded container is only 1 / 7 of its unfolded volume, which greatly saves storage space. Because the folded container occupies less space, more folded containers can be accommodated during transportation, reducing the space and number of trips required. This helps reduce transportation costs, especially in international and bulk cargo transportation, significantly reducing logistics expenses.

[0066] In this invention, features described and / or illustrated for one embodiment may be used in the same or similar manner in one or more other embodiments, and / or combined with or in place of features of other embodiments.

[0067] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
