[0034] The technical solutions adopted by the present application are further described below with reference to the embodiments and the accompanying drawings.

[0035] Embodiment 1

[0036] Referring to Figure 1 In this embodiment, the foldable box container comprises a bottom plate 1, long side plates 2, short side plates 3, and a top cover 4, wherein the bottom plate 1 and the long side plates 2 and the short side plates 3 are connected by connecting parts, the long side plates 2 and the short side plates 3 can rotate around the connecting parts, the connecting parts of the bottom plate 1 are provided with support limiting structures, which are used to prevent the side plates from being folded outward, and can also play a role of auxiliary support for the side plates in the assembled state, the upper edges of the long side plates 2 and the short side plates 3 are provided with stack-like structures, the top plate is provided with hole positions matching the stack-like structures, and the outer bottom surface of the bottom plate is provided with notches matching the stack-like structures. In this way, when loading fluid, the foldable box container can be stacked together without the top plate, and the structure is stable and not easy to slide.

[0037] Referring to Figure 2 and Figure 3 When the foldable box container is converted from the folded state to the assembled state, the long side plates 2 and the short side plates 3 are limited, and in the assembled state, the long side plates 2 are provided with a bayonet on the side, the short side plates 3 are provided with a clamping column on the side, the bayonet and the clamping column are matched and fixed, the clamping column is provided with a bending structure to fix the bayonet stably, and at this time the foldable box container can load fluid. When in the folded state, the short side plates 3 are placed down first, the height of the short side plates 3 should be less than half of the long side of the bottom plate, so that the short side plates 3 cannot overlap each other or press on the slot in the center of the bottom plate. Since the short side plates 3 are installed on the bottom plate 1, the height difference between the two sides of the bottom plate connecting the long side plates and the two sides connecting the short side plates is the thickness of the short side plates, therefore in the folded state, the short side plates 3 are placed down first, the height of the bottom plate connecting the long side plates 2 is flush with the height of the short side plates 3, and then the long side plates 2 are placed down, the two sides of the long side plates 2 are also provided with clamping grooves for clamping the bottom edges of the short side plates 3. In this way, when the foldable box container does not load fluid, the occupied space of the foldable box container can be minimized, and the foldable box container can be stacked flat, which is convenient for transportation.

[0038] Referring to Figure 4, the central part of the bottom plate 1 is provided with a slot for inserting a steel pipe, the slot protrudes from the inner bottom surface of the bottom plate, the part of the slot protruding from the inner bottom surface of the bottom plate is used to distribute the pressure of the fluid on the center of the bottom plate to both sides, preventing the liquid in the bag from accumulating in the middle of the bottom, avoiding the center of the bottom plate being crushed by excessive pressure. The steel pipe is inserted into the slot and forms a frame structure with the bottom plate, thereby enhancing the support force on the bottom plate, so that the bottom plate will not deform even when carrying fluid. If this structure is not used, the bottom plate will deform with the concentration of fluid. The main function of preventing the tank from expanding is achieved by using a long side plate made of PC material with greater strength. The outer side of the bottom plate is provided with a high-rise connecting part for linking the side plate, and the outer bottom surface is provided with hexagonal and cross-shaped support ribs, wherein the depth of the hexagonal support rib is 6mm and the wall thickness is 2.5mm, which is used to reinforce the strength of the bottom plate, and the outer bottom surface is provided with a notch around the outer bottom surface for fixing the bottom plate with the foldable box container below.

[0039] Referring to Figure 5 and Figure 6 , the outer surface of the long side plate and the short side plate is provided with intersecting reinforcing ribs, the thickness of the reinforcing rib of the long side plate is 12mm and the wall thickness is 2.5mm, and the thickness of the reinforcing rib of the short side plate is 11mm and the wall thickness is 2.5mm, which is used to prevent the fluid from expanding in the interior, the long side plate and the short side plate are provided with a handle at the middle position of the outer side, which can facilitate carrying. The RFID and / or nameplate is provided below the handle of the long side plate and is fixed on the long side plate by plastic rivets or hot melt adhesive process. The long side plate is provided with a position for pasting labels on both sides of the handle, and the position is easy to tear.

[0040] Embodiment 2

[0041] Referring to Figure 7 and Figure 8 , in this embodiment, the structure of the long side plate 2 and the short side plate 3 is as described in the above embodiment, the foldable box container comprises a bottom plate 1, a long side plate 2, a short side plate 3 and a top cover 4, wherein the bottom plate 1, the long side plate 2 and the short side plate 3 are connected by a connecting part, the long side plate 2 and the short side plate 3 can rotate around the connecting part, the connecting part of the bottom plate 1 is provided with a support limiting structure, which is used to prevent the side plate from folding outward, and can also play a supporting role in the assembled state, the upper edge of the long side plate 2 and the short side plate 3 is provided with a notch structure, the top plate is provided with a hole position matched with the notch structure, and the outer bottom surface of the bottom plate is provided with a notch matched with the notch structure, the outer surface of the top cover is a smooth structure, the inner surface is a grid structure, and the outer surface is provided with openings on both sides. In this way, when carrying fluid, the foldable box container can be stacked together without the top cover, and the structure is stable and not easy to slide. The installation method and folding principle are the same as those of the above embodiment, the difference lies inFigure 7 Base plate shown without slots and steel tube construction.

[0042] Example 3

[0043] The foldable container is placed on a pallet, which can accommodate four flat containers. The containers are arranged in a "T" (a square) pattern on the pallet, and eight steel pipes are placed inside the pallet for added strength. The pallet has support columns that mate with notches on the outer bottom surface of the foldable container to limit and secure the container. The bottom of the pallet has support grooves that mate with the crenel-like structures on the upper edges of the foldable container's side panels, providing both position and security.

[0044] The present invention will be better explained below by describing the raw rubber packing process of the present invention.

[0045] S1. Unfold the first foldable box container, put a plastic bag on it, place it under the raw rubber gate, fill it with 25 kg of raw rubber, and move the first foldable box container to the pallet.

[0046] S2. Place the second foldable container under the rubber sprue. The rubber in the first foldable container is now concentrated in the middle, 10 to 20 mm above the edge (without overflowing). Push the rubber toward each of the two short side panels 5 to 10 times. After securing the bag, push it again 5 to 10 times toward each of the two short side panels. This way, the rubber will drop to about 10 mm and slowly flow toward the four corners.

[0047] S3. Complete stacking of the first foldable box container, flattening the raw rubber, and tying the bag. The entire process takes about 50 seconds.

[0048] S4. Wait for the second collapsible container to be filled with 25 kg of raw rubber. At this point, there are 50 seconds left until the second collapsible container reaches 25 kg. After the second collapsible container is filled, it is moved to the pallet. The third collapsible container is filled with raw rubber. The second collapsible container is then flattened and the bag is tied.

[0049] S5. Continue this way, first fill one pallet with 4 single-layer containers, then place another pallet with 4 single-layer containers, and when all 8 foldable box-type containers are filled, place the 9th foldable box-type container on top of the 1st foldable box-type container.

[0050] S6. After 8 cycles of 1 minute and 40 seconds, or 13 minutes, the first foldable box-type container will have fully flowed to the four corners of the foldable box-type container, and the height of the raw rubber will be less than or equal to the edge of the foldable box-type container. After complete cooling, the height of the raw rubber will be about 20 mm lower than the foldable box-type container.

[0051] S7. On a single pallet, place 6 layers of 4 foldable box containers per layer.

[0052] The above-mentioned glue loading method is a manual glue loading method. The automatic glue loading method can be appropriately adjusted according to the above method.

[0053] During the packaging process, a single pallet is stacked with four collapsible boxes per layer, for a total of six layers. On the 1016mm side of the pallet, two strips of strapping tape are used at 200mm, 308mm, 708mm, and 816mm from left to right. The entire package is wrapped with stretch film. Two pallets, packed together, are then stacked on top of each other and wrapped with stretch film, resulting in a total size of 1016*772*2263mm.

[0054] In the specific process of loading the container, taking a conventional 20GP container as an example, at this time, the size of the plastic pallet is 1016*772*115mm, and the size of the foldable box container is 508*386*189mm. In the container, 5 rows are placed first along the length direction, and 2 pallets are placed side by side. At this time, the margin in the length direction is a margin of 46mm, and 3 rows are placed in the width direction of the container, with a margin of 34mm. In the height direction of the container, 1 pallet is placed with 6 layers of foldable box containers plus 1 lid, and 2 pallets are stacked up and down together with a margin of 17mm. Therefore, through calculation, the 20GP container can be loaded with 816 boxes of foldable boxes filled with raw rubber through the foldable box container used in the present invention. Compared with the carton, the raw rubber capacity that can be loaded in each container of the present invention is approximately increased by 5000KG. At the same time, after the transportation is completed, the present invention can be switched back to the folded state and returned by transportation to achieve the purpose of multiple utilization and cost saving.

[0055] The comparison of parameters of the present invention and the existing carton loading silica gel is shown in the following table:
