Description

Technical Field

[0001] The utility model relates to the technical field of color boxes, in particular to a foldable color box. Background Art

[0002] Folding boxes are an efficient and flexible packaging solution widely used in various product packaging applications. For example, Chinese Patent Publication No. CN205837398U discloses a folding box comprising a base and two sets of side panels—a vertical first side panel and a horizontal second side panel—flanking the base. These side panels are connected by special folding plates, ensuring structural flexibility and stability.

[0003] Specifically, the design achieves a flat form by folding the first side panel outward and the second side panel inward. Conversely, when the first side panel folds inward and the second side panel folds outward, a three-dimensional box with an opening is formed. The folding panel always remains parallel to the first side panel and perpendicular to the bottom panel in the three-dimensional state, allowing the box to quickly transition between the two states, significantly reducing storage and transportation space requirements and, in turn, lowering logistics costs.

[0004] Despite this, existing folding boxes still have some shortcomings during use: once the lid is opened, the box's structural stability relies primarily on the adhesion between the folding plate and the side panels. In this case, if subjected to external forces, the adhesion may become detached, causing the overall structure of the box to become unstable, affecting the user experience and the protection of the product.

[0005] In view of this, the inventor specially designed a folding color box, which resulted in this case. Utility Model Content
