Abstract

This invention relates to a cardboard box structure. The main feature is that the box has an internal storage space, and ventilation holes are provided on the sides. A partition film with multiple ventilation holes is also provided on both sides. The partition film is fixed to the ventilation holes, completely covering them. This allows ventilation only through the holes in the partition film. This not only prevents insects from entering the box but also ensures proper ventilation inside, making it suitable for storing various fruits and vegetables. Overall, this design enhances the box's practicality and functionality.
