Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging box that is easy to stack. Background Technology

[0002] Packaging boxes are boxes used to package products. They have functions such as protecting products, displaying products, and enhancing product quality. They are widely used in many industries such as electronics, food, beverages, wine, and cosmetics. The core of packaging boxes that are easy to stack is to have a stable support structure and uniform specification adaptability. The key to packaging boxes is that they are not easy to tip over after stacking, can evenly distribute the weight of the upper layer, and are convenient for batch stacking and space utilization.

[0003] Existing technology patent document CN217295324U discloses a novel packaging box, including a base and a cover that fastens to the base. The bottom of the base has a first groove for the top of the cover to be inserted into. At least three limiting protrusions are provided within the first groove to restrict the horizontal movement of the cover relative to the first groove. This design, using the first groove and limiting protrusions of the base, allows multiple packaging boxes to be stacked without easily shifting or collapsing, ensuring product safety. Simultaneously, the embedded stacking reduces space occupation and facilitates transportation and carrying.

[0004] The aforementioned patent specification states that "when two packaging boxes are stacked, the bottom tray of the upper packaging box rests on the lid of the lower packaging box, so that the top part of the lid extends into the first groove of the bottom tray. Since the limiting protrusion can restrict the horizontal movement of the lid relative to the first groove, the two packaging boxes will not shift relative to each other under their own weight, thus preventing displacement and collapse accidents and effectively protecting the internal products. With this design, multiple packaging boxes can be stacked through the first groove of the bottom tray and the limiting protrusion, and it is not easy to shift or collapse, ensuring the safety of the products. At the same time, the embedded stacking can reduce the space occupied and facilitate transportation and carrying." The above content can ensure that when transporting fragile items, precision electronic components, and other items with high protection requirements, the cushioning structure has poor compatibility with the box body. Therefore, a packaging box that is easy to stack is proposed to solve the above problems. Utility Model Content
