Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to an anti-extrusion corrugated paper box. Background Art

[0002] Corrugated paper box refers to a detachable paper box made of corrugated cardboard. Corrugated cardboard is made of face paper, lining paper, core paper and corrugated paper processed into corrugated waves by gluing them together. According to the needs of product packaging, corrugated cardboard can be processed into single-sided corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer corrugated cardboard, etc. Single-sided corrugated cardboard is generally used as a lining protective layer for product packaging or to make lightweight grids and pads to protect products from vibration or collision during storage and transportation. Three-layer and five-layer corrugated cardboard are commonly used in the production of corrugated boxes.

[0003] At present, traditional corrugated paper boxes have poor pressure resistance, which can easily cause damage to the box body and then damage to the items. In order to improve the pressure resistance, some corrugated paper boxes will be equipped with metal support plates between the multiple layers of corrugated paper boards. Due to the thickness limit of the corrugated paper boxes, the metal support plates arranged between the multiple layers of corrugated paper boards are relatively thin and the pressure resistance is limited. In addition, the metal support plates arranged between the multiple layers of corrugated paper boards are not easy to disassemble. In this way, the damage of the corrugated paper boxes will cause the corrugated paper boards and the metal support plates to be discarded at the same time. Since the metal support plates can be reused, the abandonment of the metal support plates will increase the procurement cost of the corrugated paper boxes.

[0004] Therefore, we proposed an anti-squeeze corrugated box to solve the above problems. Utility Model Content
