AI Technical Summary

Technical Problem

Existing corrugated cardboard boxes are prone to fatigue damage at the bends after long-term use, and the lack of reinforcement leads to a reduced service life.

Method used

The corrugated cardboard box has a reinforced structure inside, including an outer board, an inner board, a watermark, a corrugated layer, and reinforcing strips. A waterproof membrane covers the space between the outer and inner boards. The lid is securely connected by a rotating block and a slot. Anti-counterfeiting patterns are etched on the outside of the rotating block. Watermark patterns are embedded in the outer and inner boards. The corrugated layer and reinforcing strips are interwoven into a mesh structure to enhance compression resistance.

Benefits of technology

It improves the anti-counterfeiting function of corrugated cardboard boxes, ensures sealing and safety during transportation, enhances their pressure resistance, protects fragile items, and extends their service life.

Abstract

This utility model relates to the field of corrugated cardboard box technology, and provides a watermarked corrugated cardboard box with anti-counterfeiting function. It includes a box body, a lid at the top, and fixing structures on both sides of the box body and lid. An internal reinforcing structure is provided inside the box body, including an outer panel inside the box body and an inner panel on one side of the outer panel. Watermarks are fixed on both sides of the outer and inner panels. This utility model, through the reinforcing structure and the use of a special process to embed watermark patterns on the surfaces of the outer and inner panels, provides anti-counterfeiting protection for both the exterior and interior of the box. The curved corrugated layers and buffer cavity form a cushioning structure, effectively absorbing vibrations and impacts during transportation and protecting fragile items. Furthermore, the cross-weaving of the first and second reinforcing strips enhances the overall compressive strength, making it less prone to deformation.
