Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a high-strength packaging paper box. Background Art

[0002] Packaging cartons are made of paper products and are used to pack various items. Cartons are divided into paper boxes, color boxes, color boxes, and large-sized odd-shaped beer boxes. Cartons are low-cost, easy to pack, suitable for adding fillers, clean, and suitable for product factory packaging, item transportation, material sorting, etc. Existing packaging cartons have low strength due to the limitations of their own materials; if you want to improve the structural strength of the carton, you generally use measures to increase the thickness of its paperboard.

The utility model can support the side of the carton body by using a plurality of transverse reinforcing ribs, a plurality of longitudinal reinforcing ribs and a plurality of fixing rods through the arrangement of the first anti-pressure member and the second anti-pressure member. When a plurality of carton bodies are stacked up and down or squeezed by the outside world, the transverse reinforcing ribs, the longitudinal reinforcing ribs and the fixing rods can bear a part of the force, ensuring that the side of the carton body is subjected to less force and will not be greatly deformed, thereby improving the compression resistance and strength of the carton body.

[0004] However, the above technical solution has the following defects: in the above high-strength packaging paper box, multiple longitudinal and transverse reinforcing ribs are arranged inside the paper box, which enhances the strength of the paper box but makes the internal surface of the paper box uneven, and objects placed inside are easily damaged by bumps when they are shaken.
