[0002] Carton packaging refers to the packaging of products in paper boxes to protect them, facilitate storage and transportation, and promote sales during their distribution. Carton packaging is the most widely used packaging method. Different from wooden crates, woven bags, cloth bags, and plastic boxes, carton packaging offers advantages such as ease of material sourcing, light weight, ease of printing, ease of design and molding, and low cost. It is widely used for both sales and transportation packaging.

[0003] Packaging cartons are divided into corrugated cartons, single-layer cardboard boxes, etc. according to the different paper materials. However, no matter what material is used, the cartons often need to be glued together in the end to ensure their own stability. However, cartons glued together with glue are often difficult to disassemble into their original cardboard state, which means that they take up a lot of space when they are no longer in use and are stored. Utility Model Content

[0005] The utility model is implemented as follows: a carton with a glue-free bonding structure includes a carton board, two sides of the carton board are respectively transversely opened with three first slots and a second slot, the plurality of first slots and the plurality of second slots correspond to each other, the carton board is bent from front to back along the width direction between every two corresponding first slots and second slots to form a first side box board, a second side box board, a third side box board and a fourth side box board;

[0006] An extension plate is fixedly connected to the middle of the front end of the first side box panel, and side arm plates are fixedly connected to the two side surface surfaces in the transverse direction. The middle parts of the two side arm plates are bent along the length direction of the carton board to form bending marks. A through opening that is compatible with the specifications of the extension plate is opened in the middle of the rear end of the outer surface of the fourth side box panel, and through grooves corresponding to the bending places of the two side arm plates are respectively opened on both sides of the rear end of the outer surface of the fourth side box panel.

[0007] Preferably, one side of the carton board is bent along the length direction between every two adjacent first cut grooves to form a plurality of box top panels.

[0008] Preferably, the other side of the carton board is bent along the length direction between every two adjacent second cut grooves to form a plurality of box bottom boards.

[0009] Preferably, the first side box panel and the third side box panel have the same specifications.

[0010] Preferably, the second side box panel and the fourth side box panel have the same specifications.

[0011] Preferably, the carton board is corrugated cardboard.

[0012] Beneficial effects

[0013] Compared with the prior art, the beneficial effect of the present invention is as follows: the present invention is a carton with a glue-free adhesion structure, by setting an extension plate, a side arm plate, a through-opening and a through-groove. When the carton is assembled, the extension plate and the side arm plate are fitted on the inner side of the fourth side box panel, and then the side arm plates on both sides of the extension plate are bent backward and inserted into the inside of the through-groove. At this time, the two side arm plates are located on the outside of the fourth side box panel, and then the two side arm plates are bent forward along the folds thereon and respectively passed through the two through-grooves and sent into the inner side of the fourth side box panel, and then the parts of the two side arm plates located on the inner side of the fourth side box panel are bent toward the inner surface of the fourth side box panel to make the two fit together. At this time, the connection between the first side box panel and the fourth side box panel can be completed, and no glue is required in the entire process, which ensures stability while also making the carton easier to store.
