Description

Technical Field

[0001] This utility model relates to the field of cardboard box manufacturing technology, and in particular to a high-strength, pressure-resistant cardboard box. Background Technology

[0002] Cardboard boxes, as an important product in the modern logistics and packaging field, are lightweight, recyclable, and inexpensive, making them the preferred alternative to traditional packaging materials such as wood and plastic. They are widely used in the transportation and storage of goods such as food, electronic products, daily chemical products, and industrial parts.

[0003] During use, cardboard boxes must withstand vertical stacking pressure, horizontal impact, and environmental stress. Especially during multi-layer stacking, the bottom box must withstand longitudinal pressure several times its own weight. This can damage the structural strength of boxes with insufficient compression resistance, leading to deformation and posing a risk of damage to the products inside. Furthermore, if cardboard boxes are exposed to a humid environment for extended periods, they may absorb moisture, weakening their compression resistance. If a cardboard box lacks sufficient compression resistance, it is highly susceptible to moisture, which can cause deformation or even collapse.

[0004] Therefore, in order to meet the requirements for the compression resistance of cartons in practical use, it is necessary to provide a high-strength compression-resistant carton. Utility Model Content

[0005] In view of the requirements for strength and compression resistance of existing cardboard boxes, this utility model provides a high-strength compression-resistant cardboard box.

[0006] A high-strength compression-resistant cardboard box includes a box body with an open top and a box lid that fastens to the top of the box body. The box body includes an outer box body and an inner box body disposed inside the outer box body. An L-shaped locking block is provided between the outer corner of the inner box body and the inner corner of the corresponding outer box body. A plurality of first compression-resistant columns are fixedly connected between the inner box body and the outer box body. The first compression-resistant columns are evenly arranged longitudinally and located on one side of the L-shaped locking block. Adjacent first compression-resistant columns are fixedly connected to each other by a second compression-resistant column, and the second compression-resistant columns are all arranged laterally. The first and second compression-resistant columns are both cylindrical and include a circular core column. A cross-shaped fixing bracket is fixedly connected inside the circular core column. A plurality of column feet are provided at the bottom of the box body, and a plurality of alignment holes matching the column feet are provided at the top of the box lid.

[0007] Furthermore, the core column is filled with several moisture-proof particles, which are located on the outside of the cross-shaped fixing frame; a first waterproof layer is provided on the outer surface of the core column.

[0008] Furthermore, the moisture-proof particles are silica gel particles or activated carbon particles.

[0009] Furthermore, a reinforcing rib is provided at the center of the cross-shaped fixing frame.

[0010] Furthermore, the box body, box lid, and round core column are all made of cardboard, the cardboard including a core layer and a first corrugated core paper layer and a second corrugated core paper layer respectively disposed on both sides of the core layer; a second waterproof layer is provided on the outer side of both the first corrugated core paper layer and the second corrugated core paper layer.

[0011] Furthermore, a buffer layer is provided between the first corrugated core paper layer and the second waterproof layer on its outer side, and an antibacterial layer is provided between the second corrugated core paper layer and the second waterproof layer on its outer side.

[0012] Furthermore, an anti-slip rubber pad is provided at the bottom of the box, and the anti-slip rubber pad has several anti-slip patterns.

[0013] Furthermore, a corner protector is provided at each of the bottom corners of the box.

[0014] Furthermore, a hand-holding groove is provided on each of the outer sides of the box body.

[0015] Furthermore, an X-shaped support frame is fixed inside the box cover.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a high-strength compression-resistant cardboard box. An L-shaped locking block is provided between the outer corner of the inner box and the inner corner of the corresponding outer box. Several longitudinally arranged first compression-resistant columns are fixedly connected between the inner and outer boxes, and second compression-resistant columns are transversely arranged between adjacent first compression-resistant columns to connect them. This effectively strengthens the overall structural strength of the box and enables the box to effectively withstand and disperse the longitudinal pressure, thus significantly improving the box's compression resistance. Simultaneously, each of the first and second compression-resistant columns includes a circular core column, and a cross-shaped fixing frame is fixedly connected inside the core column. The cross-shaped fixing frame supports the structure of the core column, improving torsional strength and dispersing the pressure on the core column, thereby enhancing the compression resistance of the first and second compression-resistant columns.

[0017] In addition, by providing several pillars at the bottom of the box and several matching alignment holes at the top of the box lid, the pillars of the upper box can be inserted into the alignment holes of the lower box when the boxes are stacked. This improves the stability of the stacking and enhances the box's resistance to pressure during use, thus better protecting the contents of the box. Attached Figure Description

[0025] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] refer to Figure 1 As shown, a high-strength compression-resistant carton includes a box body 1 with an open top and a box lid 2 that is fastened to the top of the box body.

[0027] Specifically, refer to Figure 2 , Figure 3 and Figure 5 As shown, the housing 1 includes an outer housing 11 and an inner housing 12 disposed inside the outer housing 11; an L-shaped locking block 3 is provided between the outer corner of the inner housing 12 and the inner corner of the corresponding outer housing 11. In this embodiment, the outer sides of the L-shaped locking blocks 3 are respectively glued and fixed to the outer corner of the inner housing 12 and the inner corner of the corresponding outer housing 11.

[0028] By installing L-shaped blocks 3 at the corner connection between the inner box 12 and the outer box 11, a triangular mechanical support structure is formed. This structure effectively disperses the external impact force and internal load-bearing pressure on the box 1, while enhancing the strength of the box 1 and improving its overall resistance to bending and torsion. Furthermore, when the boxes 1 are stacked, the L-shaped blocks 3 provide good support, ensuring the stability of the box 1 and extending its lifespan.

[0029] A plurality of first pressure-resistant columns 4 are fixedly connected between the inner box 12 and the outer box 11. The first pressure-resistant columns 4 are evenly arranged longitudinally and are located on one side of the L-shaped card block 3. Adjacent first pressure-resistant columns 4 are fixedly connected by a second pressure-resistant column 5, and the second pressure-resistant columns 5 are all arranged laterally.

[0030] The first pressure-resistant columns 4 are evenly arranged longitudinally, effectively resisting longitudinal pressure. The second pressure-resistant columns 5 are laterally connected to the adjacent first pressure-resistant columns 4, giving the entire box good lateral pressure resistance as well. This strengthens the structural strength of the box from multiple directions, ensuring its stability under external forces from different directions and preventing deformation or damage. The first and second pressure-resistant columns 4 and 5 provide excellent pressure protection and support for the outer perimeter and bottom of the box 1, effectively improving its structural strength, enhancing its support and pressure resistance, and enabling it to effectively withstand and disperse longitudinal pressure, thus significantly improving its overall pressure resistance.

[0031] Both the first compression-resistant column 4 and the second compression-resistant column 5 are cylindrical, and both the first compression-resistant column 4 and the second compression-resistant column 5 include a circular core column 41, and a cross-shaped fixing bracket 42 is fixedly connected inside the circular core column 41.

[0032] The circular core column 41 is further filled with a plurality of moisture-proof particles 43, which are located outside the cross-shaped fixing frame 42; a first waterproof layer 44 is provided on the outer surface of the circular core column 41. In this embodiment, the moisture-proof particles 43 are silica gel particles or activated carbon particles.

[0033] The first waterproof layer 44 can isolate water and moisture, preventing water and moisture from entering the interior of the round core column 41 and affecting the compressive performance of the first compressive column 4 and the second compressive column 5. The cross fixing bracket 42 supports the structure of the round core column 41, which can improve the torsional strength, thereby dispersing the pressure on the round core column 41 and improving the compressive effect of the first compressive column 4 and the second compressive column 5.

[0034] The cross-shaped fixing frame 42 is provided with a reinforcing rib 45 at its center. The reinforcing rib 45 can further improve the supporting force of the round core column 41, thereby enabling the first compression column 4 and the second compression column 5 to have excellent compression resistance.

[0035] refer to Figure 3 , Figure 4 As shown, the box body 1, the box cover 2 and the round core column 41 are all made of cardboard. The cardboard includes a core layer 21 and a first corrugated core paper layer 22 and a second corrugated core paper layer 23 respectively disposed on both sides of the core layer 21. A second waterproof layer 24 is provided on the outer side of the first corrugated core paper layer 22 and the second corrugated core paper layer 23.

[0036] The second waterproof layer 24 effectively prevents moisture from entering the internal structure of the box 1 from both inside and outside, thus avoiding damage to the box 1 structure due to moisture absorption. The first corrugated core paper layer 22 and the second corrugated core paper layer 23 can evenly distribute external stress across the core layer 21, thereby improving its load-bearing capacity and compressive strength. Optionally, the center point between the crest and trough of each wave in the first corrugated core paper layer 22 and the second corrugated core paper layer 23 is connected to the center point between the crest and trough of the adjacent wave by a connecting plate, thereby further enhancing the compressive strength of the first corrugated core paper layer 22 and the second corrugated core paper layer 23.

[0037] A buffer layer 25 is provided between the first corrugated core paper layer 22 and the second waterproof layer 24 on its outer side, and an antibacterial layer 26 is provided between the second corrugated core paper layer 23 and the second waterproof layer 24 on its outer side.

[0038] The buffer layer 25 effectively absorbs and disperses impact forces, reducing the direct impact on the inner first corrugated core paper layer 22. The antibacterial layer 26 effectively inhibits bacterial growth, reducing damage to the box 1 and the internal products caused by bacteria. In this embodiment, the buffer layer 25 is a honeycomb structure layer; the antibacterial layer 26 is a bamboo charcoal fiber layer.

[0039] The bottom of the box body 1 is provided with several pillars 6, and the top of the box cover 2 is provided with several alignment holes 7 that match the pillars 6.

[0040] By providing several pillars 6 at the bottom of the box body 1 and several matching alignment holes 7 at the top of the box cover 2, the box body 1 is isolated from the ground when placed on the ground, and the pillars 6 of the upper box are embedded in the alignment holes 7 of the lower box when the boxes are stacked. This improves the stability of the boxes and enhances their compressive strength during use, thus better protecting the contents of the boxes.

[0041] In some embodiments, an X-shaped support frame (not shown in the figure) is fixed to the inner side of the box cover 1. The X-shaped support frame, through its intersecting support structure, can effectively disperse the force on the box cover 1, reduce local stress concentration, thereby significantly enhancing the overall structural strength of the box cover 1, effectively resisting bending and torsional deformation of the box cover 1, making the box cover 1 less prone to deformation or damage when subjected to external impact or bearing heavy objects, and improving the compressive strength of the box cover 1.

[0042] refer to Figure 3 As shown, in some embodiments, an anti-slip rubber pad 8 is provided at the bottom of the inner side of the box 1, and the anti-slip rubber pad 8 has several anti-slip patterns (not shown in the figure). The anti-slip rubber pad 8, through the anti-slip pattern, can increase the coefficient of friction between the product inside the box 1 and the bottom of the box 1, thereby reducing the risk of product displacement caused by transportation vibration. At the same time, the anti-slip rubber pad 8 is made of silicone, which can absorb impact energy through deformation, buffering the pressure and impact force on the product inside the box 1.

[0043] refer to Figure 1 As shown, in some embodiments, a corner protector 9 is provided at the bottom corner of the box body 1. The corner protector 9 enhances the structural strength of the bottom corner of the box body 1, preventing damage to the corner due to collision, friction, or concentrated pressure; at the same time, it can disperse the pressure when the boxes are stacked, reduce the occurrence of box deformation, and thus improve the stability of stacking.

[0044] In some embodiments, a handle groove 10 is provided on each of the outer sides of the box 1 to facilitate the user to move the carton to the corresponding position.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model and do not limit the utility model to the specific implementations described. Obviously, other modifications and variations can be made based on the content of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. They are not intended to limit the utility model, and any simple modifications to this utility model fall within the protection scope of this utility model.
