Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically to a wide-width, bend-resistant corrugated cardboard box. Background Technology

[0002] Corrugated cardboard boxes are made from corrugated cardboard through die-cutting, creasing, stapling, or gluing. Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated cardboard boxes. For over half a century, corrugated cardboard boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging.

[0003] To meet the market demand for large-capacity cardboard boxes, manufacturers typically use wide-width corrugated cardboard to produce them, giving them a larger capacity. However, this reduces the cardboard's resistance to bending, making the boxes more susceptible to deformation and damage from external forces. Furthermore, the limited structural strength of the cardboard box poses a significant risk of damage to the contents inside. Summary of the Invention

[0004] The purpose of this utility model is to provide a wide-width, bend-resistant corrugated cardboard box to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a wide-width anti-bending corrugated cardboard box, comprising a bottom plate, a lid, and a box body formed by several side plates. The bottom of the bottom plate is provided with an anti-bending plate. The side plates include an outer paper layer and an inner paper layer. The outer paper layer and the inner paper layer are connected by several spaced reinforcing strips. An anti-bending spring is provided between every two adjacent reinforcing strips. An L-shaped connecting piece is provided between every two adjacent side plates. The two sides of the inner paper layer are fixedly connected to the inner side of the corresponding connecting piece. The two sides of the outer paper layer are fixedly connected to the outer side of the corresponding connecting piece. The bottom of the box body is detachably connected to the bottom plate, and the top is detachably connected to the lid.

[0006] By employing the above technical solutions, the side panels are configured with inner and outer paper layers, giving them a certain thickness and improving structural strength. When the box is subjected to external force and bends, the anti-bending springs deform, generating potential energy. When the external force disappears, the anti-bending springs return to their original shape, thus restoring the box's original shape and reducing the likelihood of damage or deformation caused by bending. Connecting plates provide better rigidity and structural strength at the corners of the box, reducing the probability of bending and wear at these corners. A bottom plate connects to the box, and an anti-bending plate enhances the bottom plate's bending strength, making it less prone to deformation and providing support and protection for the box.

[0007] As a further optimization of this utility model, both the outer surface of the outer paper layer and the inner surface of the inner paper layer are provided with cross-shaped reinforcing strips.

[0008] By adopting the above technical solution, reinforcing strips are set on both the inner and outer sides of the side panel to further improve the impact resistance and bending resistance of the side panel.

[0009] As a further optimization of this utility model, the upper surface of the base plate is provided with a raised first enclosure portion, the first enclosure portion having a first slot, the bottom of the side plate being provided with a first groove, and the first groove containing a first locking block capable of engaging with the first slot.

[0010] By adopting the above technical solution, the side panel and the bottom panel can be detachably connected. The first enclosure can clamp and fix the bottom of the side panel, further improving the bending resistance of the side panel.

[0011] As a further optimization of this utility model, the lower surface of the box cover is provided with a raised second enclosure, the second enclosure is provided with a second slot, the top of the side plate is provided with a second groove, and a second locking block is provided in the second groove that can engage with the second slot.

[0012] By adopting the above technical solution, the side panel and the box cover can be detachably connected, and the second enclosure can clamp and fix the upper end of the side panel, further improving the bending resistance of the side panel.

[0013] As a further optimization of this utility model, the cross-sectional shape of both the first card block and the second card block is teardrop-shaped, the shape of the first card slot is adapted to the shape of the first card block, and the shape of the second card slot is adapted to the shape of the second card block.

[0014] As a further optimization of this utility model, the lower surface of the box cover is provided with a support frame extending downward.

[0015] By adopting the above technical solutions, the support frame can provide better support for the inner side of the side panel, further improving the bending resistance of the side panel.

[0016] The beneficial effects of this utility model are as follows: The side panels are configured with inner and outer paper layers, giving them a certain thickness and improving structural strength. When the box is subjected to external force and bends, the anti-bending spring deforms and generates potential energy. When the external force disappears, the anti-bending spring returns to its original shape, thus restoring the shape of the box and reducing damage and deformation caused by bending. The connecting plate provides better hardness and structural strength at the corners of the box, reducing the probability of bending and wear at the corners. The bottom plate connects to the box, and the anti-bending plate improves the bending strength of the bottom plate, making it less prone to deformation and providing support and protection for the box.

[0026] See appendix Figure 1-7 The present embodiment of the present utility model further includes: a wide-width anti-bending corrugated cardboard box, comprising a bottom plate 11, a box cover 13 and a box body formed by several side plates 12, wherein an anti-bending plate 111 is provided at the bottom of the bottom plate 11;

[0027] The side panel 12 includes an outer paper layer 31 and an inner paper layer 32. The outer paper layer 31 and the inner paper layer 32 are connected by a number of spaced reinforcing strips 4. An anti-bending elastic piece 5 is provided between every two adjacent reinforcing strips 4. An L-shaped connecting piece 6 is provided between every two adjacent side panels 12. Specifically, the connecting piece 6 is made of plastic or metal. The two sides of the inner paper layer 32 are fixedly connected to the inner side of the corresponding connecting piece 6, and the two sides of the outer paper layer 31 are fixedly connected to the outer side of the corresponding connecting piece 6.

[0028] The bottom of the box is detachably connected to the bottom plate 11, and the top is detachably connected to the box cover 13. Specifically, the upper surface of the bottom plate 11 is provided with a raised first enclosure 21, and the first enclosure 21 has a first slot 211. The bottom of the side plate 12 is provided with a first groove 121, and the first groove 121 has a first locking block 1211 that can engage with the first slot 211. The lower surface of the box cover 13 is provided with a raised second enclosure 22, and the second enclosure 22 has a second slot 221. The top of the side plate 12 is provided with a second groove 122, and the second groove 122 has a second locking block 1221 that can engage with the second slot 221. Furthermore, the cross-sectional shape of the first locking block 1211 and the second locking block 1221 are both teardrop-shaped.

[0031] The principle of this utility model is as follows: the side plate 12 is set as an inner paper layer 32 and an outer paper layer 31, so that the side plate 12 has a certain thickness, which improves the structural strength. When the box is subjected to external force and bends, the anti-bending spring 5 deforms and generates potential energy. When the external force disappears, the shape of the anti-bending spring 5 is restored, thereby restoring the shape of the box and reducing the damage and deformation of the box caused by bending.
