[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Carton packaging refers to the packaging of products in paper boxes in the process of circulation to protect products, facilitate storage and transportation, and promote sales. Packaging cartons are the most widely used packaging tools. Different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging, packaging cartons have the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. They are widely used in sales packaging and transportation packaging of goods. With the rapid development of e-commerce and logistics industries, the demand for packaging cartons is growing. After the traditional packaging cartons are used, they are often large in size and fixed in structure, which makes them inconvenient to fold and store, occupying a lot of space and increasing logistics and warehousing costs. Although there are some foldable carton designs on the market, these designs are often complex in structure and cumbersome in folding steps, making it difficult for users to fold and fold quickly and effectively.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a packaging carton that is easy to fold. Figure 1, including a carton body 1, a tightening belt 6 is symmetrically provided at the bottom of one end of the carton body 1, the tightening belt 6 is in the shape of a thick paper strip, and the inner wall of the tightening belt 6 is equidistantly provided with a plurality of tooth blocks 7, the tooth blocks 7 are of a corrugated paper structure, and a positioning buckle 4 adapted to the tightening belt 6 is connected at the corner of the top of the carton body 1, and a card slot 5 adapted to the tooth block 7 is provided inside the positioning buckle 4. When the carton body 1 is folded, the tightening belt 6 can be passed through the positioning buckle 4 so that the carton body 1 can be folded together and positioned, which has a good storage effect and prevents loosening.

[0020] like Figure 2 As shown, a group of folding lines 3 are provided on the outer wall of the carton body 1, and inner folding lines 8 are provided on both sides of the inner wall of the carton body 1, so that the carton body 1 can be folded inwardly along the folding lines 3 and the inner folding lines 8 to reduce the occupied area;

[0021] A central cardboard 9 for support is connected at the center of the carton body 1, and both ends of the outer wall of the central cardboard 9 are provided with corrugated paper pads 15 to improve the supporting strength. Both ends of the central cardboard 9 are provided with packaging chambers 10, and products can be stored in the packaging chambers 10.

[0022] Combination Figure 3 As shown, the bottom of both sides of the carton body 1 is connected to the side paperboard 2, the side wall of the side paperboard 2 is symmetrically provided with a group of folding pieces 11, and the outer wall of the carton body 1 is symmetrically provided with a group of fastening grooves 14. When the side paperboard 2 is covered, the folding pieces 11 can be folded into the fastening grooves 14 for fastening, and folding grooves 13 are provided on both sides of the top of the carton body 1;

[0023] One end of the side paperboard 2 away from the carton body 1 is connected with a folding strip 12 matched with the folding groove 13 , and the folding strip 12 is also folded and fastened in the corresponding folding groove 13 , thereby completing the packaging and sealing of the carton body 1 .

[0024] The implementation principle of the foldable packaging carton of the embodiment of the present application is as follows: during daily storage, the carton body 1 is folded inward along the folding line 3 and the inner folding line 8, and the carton body 1 can be bent along a specific direction when it needs to be folded, so as to achieve rapid folding of the carton body 1. At this time, the side paperboards 2 can be folded and placed on the top of the carton body 1, and then the tightening belt 6 is passed through the positioning buckle 4, and the tooth block 7 is frictionally fastened with the card slot 5, so that the carton body 1 can be folded and locked together, which plays a good storage role and avoids loosening. When packaging the product, the above operation is reset, and the product is placed on the center paperboard. 9 is placed in the packaging chambers 10 at both ends and fits against the inner wall of the carton body 1, and is covered with side paperboards 2 at both ends. The side paperboards 2 are made of a harder material and can provide good supporting force. The side paperboards 2 are tightly fitted to the carton body 1, and the folding pieces 11 are adjusted to be inserted into the fastening grooves 14 on both sides and fastened, and then the folding strips 12 are operated to be inserted into the folding grooves 13 on the top and fastened, thereby completing the packaging of the product and the sealing of the carton body 1, and being used to lock the shape of the carton body 1 after it is folded to prevent the carton body 1 from unfolding by itself during storage or transportation. The whole process is simple and quick, which greatly improves the storage and transportation efficiency of the carton body 1.
