AI Technical Summary
Existing folding boxes are inadequate in terms of space utilization and versatility, and their structure is not robust enough.
The inner rectangular folding box is securely connected to the outer protective cardboard shell. Combined with the snap-fit design of the partition reinforcement components and magnetic attraction, the internal space utilization and overall structural strength of the box are enhanced.
It significantly improves the utilization rate of the internal space of the box and the overall structural strength, enhances the sturdiness and aesthetics of the folding box, simplifies the production process, and strengthens the pressure resistance.
