[0002] Cardboard boxes are a common packaging material widely used in logistics transportation and commodity storage.

[0003] However, existing cardboard boxes have significant shortcomings in terms of compression resistance. Traditional cardboard boxes mainly rely on the corrugated structure of the box itself for support, lacking effective lateral and longitudinal reinforcement designs, which makes them prone to structural failure when subjected to torsional forces, affecting the safety of the items inside the box.

[0004] Therefore, we propose a pressure-resistant cardboard box structure. Utility Model Content

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] This embodiment is a pressure-resistant cardboard box structure.

[0029] like Figure 1-4 As shown, the carton body 1 is made of BC double corrugated cardboard. Three ring reinforcing ribs 2 are glued at equal intervals on its outer wall. The ring reinforcing rib 2 is a hollow paper tube with a cross section of 20×20mm. A through groove 4 with a width of 8mm and a depth of 15mm is opened on its inner wall. The vertical reinforcing rib 3 is made of AB corrugated cardboard cut into 15×15mm square columns. The corrugation direction is perpendicular to the ring reinforcing rib 2. A bamboo fiber strip reinforcing core 6 with a diameter of 8mm is embedded in the vertical reinforcing rib 3. The fiber strip is treated with zinc borate solution. The vertical reinforcing rib (3) is pressed into the through groove 4 with a pressure of 0.2MPa by a press to form an interference fit. PVAc adhesive is applied to the joint and cured. The bottom ring reinforcing rib is 40mm away from the bottom of the box. The distance between adjacent ring reinforcing ribs is 1 / 4 of the height of the box. The two ends of the vertical reinforcing rib 3 are processed with 45° chamfers 5 to smoothly transition with the edge of the box.
