Description

Technical Field

[0001] The present application relates to the technical field of storage boxes, and in particular to a drawer box. Background Art

[0002] As a leader in modern home storage solutions, drawer-style cardboard storage boxes, with their unique design and material advantages, are becoming a valuable tool for organizing spaces in many homes. Their drawer-like design cleverly divides the space into multiple independent areas, allowing for organized storage of various items. This not only improves the cleanliness of the living environment but also greatly enhances space utilization efficiency. Furthermore, the choice of cardboard ensures both durability and affordability, making these storage boxes highly popular in the market.

[0003] While enjoying the convenience of drawer-style cardboard storage boxes, we also have to face a significant problem. A popular design on the market utilizes cardboard for both the outer shell and inner box. While this design strikes a balance between cost control and durability, the rough surface and high friction of cardboard present significant challenges to the sliding of the inner box.

[0004] Specifically, when the user tries to open or close the inner box, due to the large friction between the outer wall of the inner box and the inner wall of the outer shell, additional force is often required to complete the operation. This undoubtedly reduces the convenience of using the storage box and affects the user experience, leaving room for improvement. Utility Model Content

[0005] The purpose of the present application is to provide a drawer box to solve the problem that the drawer-type storage box in the above-mentioned related art is inconvenient when being pulled out.
