Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper boxes, in particular to a self-locking corrugated box. Background Art

[0002] Corrugated paper is a sheet made by gluing together liner paper and corrugated paper formed by corrugating rollers. It is generally divided into single-corrugated and double-corrugated cardboard, and is categorized by flute size into five types: A, B, C, E, and F. The invention and application of corrugated paper dates back over a century. It boasts advantages such as low cost, lightweight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper is recyclable and can be used for packaging of food and digital products. It is relatively environmentally friendly and widely used.

[0003] The existing corrugated box needs to be sealed with tape during use. This method not only wastes a certain amount of tape, but also requires two people to cooperate in sealing when in use. This sealing method wastes a lot of manpower and material resources. For this reason, we propose a self-locking corrugated box. Summary of the Invention

The third box body plate 3 and the fourth box body plate 4 form a complete integral interior. When the first self-locking plate 16 and the second self-locking plate 17 are inserted into the second card slot 13, they can be opened, so that the first self-locking plate 16 and the second self-locking plate 17 can be used to complete the self-locking of the bottom sealing plate 7. Then, when the items are put in, they can be pressed on the top of the opened first self-locking plate 16 and the second self-locking plate 17, so that the first self-locking plate 16 and the second self-locking plate 17 can be clamped more firmly. After the bottom sealing plate 7 is assembled, the two groups of top sealing plates 6 are bent, and then the third self-locking plate 21 and the fourth self-locking plate 22 are bent along the second bending line 23 for the first step.
