AI Technical Summary

Technical Problem

Traditional cardboard boxes are inadequate in terms of load-bearing capacity, compression resistance, and cushioning protection. They are prone to deformation, crushing, or cushioning failure, which can lead to damage to the contents during storage and transportation.

Method used

A foldable reinforced cardboard box was designed, comprising a box body, a frame mechanism, and an internal support mechanism. The frame mechanism contains an internal support mechanism and a pad, forming a two-way support structure to enhance the overall support strength. It can be assembled and disassembled by folding.

Benefits of technology

It significantly improves the support strength and protective performance of the cardboard box, ensuring that the contents are not damaged, while also facilitating assembly and environmentally friendly recycling.

Abstract

This utility model belongs to the field of paper box manufacturing technology, specifically relating to a foldable reinforced paper box, including a box body and a frame mechanism disposed within the box body. The frame mechanism has internal support mechanisms on both its upper and lower sides, and a pad overlapping the lower internal support mechanism is also disposed within the frame mechanism. This utility model, through the cooperation of the box body, frame mechanism, and internal support mechanisms, forms a two-way support structure inside the box body, constituting a double protection system with the box body, significantly improving the overall support strength of the box body. This structure can effectively resist the impact of collapse or collision, maintaining the integrity of the box body shape and ensuring that the internal items are not damaged, thereby enhancing the protective performance and practical value of the paper box.
