Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of corrugated cartons, and specifically relates to a compression-resistant corrugated carton. Background Art
[0002] Corrugated cardboard is made into corrugated cartons through die-cutting, indentation, box nailing or gluing. For more than half a century, corrugated cartons have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting goods, facilitating warehousing and transportation, it also plays a role in beautifying and promoting goods. Corrugated cartons are green environmental protection products, which are conducive to environmental protection and handling and transportation.
[0003] At present, most corrugated cartons are directly folded from corrugated cardboard, so their structural strength is relatively low and their compression resistance is weak. In actual transportation, corrugated cartons often need to be stacked together. When the transported goods are heavy, the corrugated cartons at the bottom are prone to deformation under the heavy pressure of the upper corrugated cartons, resulting in damage to the goods and poor use effect. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem that in actual transportation, corrugated cartons often need to be stacked together. When the transported goods are heavy, the corrugated cartons at the bottom are prone to deformation under the heavy pressure of the upper corrugated cartons, resulting in damage to the goods and poor use effect.
[0005] The utility model realizes the above purpose through the following technical solutions: provide a compression-resistant corrugated carton, including an outer box body. An inner box body is arranged inside the outer box body. A first frame body and a second frame body for clamping the bottom and top of the inner box body are respectively arranged at the inner bottom and the top of the outer box body. A plurality of insertion openings are respectively formed corresponding to the inner sides of the first frame body and the second frame body. Compression-resistant bars are inserted and matched in the upper and lower insertion openings, and one side of the compression-resistant bar is closely attached to the outer side of the inner box body.
[0006] Further, the first frame body and the outer box body are integrally arranged, and the first frame body is arranged at the inner bottom of the outer box body for clamping the bottom of the inner box body.
[0007] Further, the second frame body is arranged at the top of the inner box body, and corner clamping blocks are arranged at the four corners of the second frame body, and the corner clamping blocks clamp the four corners of the outer box body.
[0008] Further, the insertion opening is triangular, and the compression-resistant bar is a triangular strip-shaped column.
[0009] Furthermore, corner strengthening blocks are provided at the four corners of the bottom of the outer box body. A support frame is connected to the bottom surface of the outer box body, and the bottom surfaces of the corner strengthening blocks and the support frame are flush.
[0010] Furthermore, the outer box body includes a corrugated paper layer. An inner paper layer is fixedly bonded to one side of the corrugated paper layer. A strengthening layer is fixedly bonded to the side of the corrugated paper layer away from the inner paper layer. Waterproof coating layers are coated on the sides of the strengthening layer and the inner paper layer away from the corrugated paper layer.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. By providing a first frame body and a second frame body between the inner and outer box bodies, and through the cooperation of the insertion ports and the inserted compression bars, the compressive performance of the entire packaging box is significantly enhanced. The compression bars can effectively disperse and absorb external pressure, preventing the inner box body from being squeezed and deformed during transportation and storage.
[0013] 2. The first frame body and the outer box body are integrally provided, enhancing the stability of the overall structure and avoiding the reduction of the protection effect due to separation during use. This design ensures that the bottom of the inner box body can be firmly clamped, thereby reducing the impact of movement and vibration on the inner box body; the second frame body is clamped at the four corners of the outer box body through corner clamping blocks. This design can increase the protection of the four corners of the outer box body through the structure of the corner clamping blocks. The four corners are the most vulnerable parts of the box, and this design greatly improves the overall strength of the box.
[0014] 3. The insertion ports are designed as triangles and are used in conjunction with triangular compression bars. Such a shape design is not only convenient for insertion and disassembly, but also the triangular structure itself has high stability and can more effectively resist external pressure, improving the durability of the packaging box.
[0015] 4. The design of the corner strengthening blocks and the support frame at the four corners of the bottom of the outer box body not only improves the strength and wear resistance of the bottom of the box, but also makes the bottom surfaces of the corner strengthening blocks and the support frame flush, ensuring the stability during stacking; in addition, the combination of the corrugated paper layer, the inner paper layer and the strengthening layer, and the coating of waterproof coating layers on both sides not only enhances the structural strength of the box, but also provides good waterproof performance, preventing the box from being damaged due to a humid environment.
