Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a connection structure of a carton. Background Art

[0002] As an important logistics packaging material, the performance of cartons is directly related to the safe transportation and storage of products. Currently, existing cartons have defects such as soft structure and easy deformation, and it is difficult to maximize the use of cardboard during the production process:

[0003] Improper structural design: The size, shape, and internal structure of a carton directly affect its compressive strength and stability. If the carton's dimensions fail to fully consider the weight and distribution of the load, as well as the forces applied during transportation, the carton can easily deform under pressure.

[0004] Insufficient cardboard plies and thickness: The number and thickness of a carton's cardboard directly determine its overall strength and rigidity. If the number of cardboard plies is not designed properly or the cardboard thickness does not meet the requirements, the carton will easily deform when subjected to external forces. This may be due to uneven cardboard thickness caused by wear on the corrugating rollers during use, or the use of thinner cardboard to reduce costs.

[0005] Insufficient utilization of cardboard: Due to the irregular shape of the cardboard used to splice cartons, it is difficult to achieve efficient utilization of cardboard in the actual production process, and a large amount of scraps are discarded.

[0006] Therefore, there is an urgent need for a new carton connection structure to provide an effective solution to the defects of the existing technology. Utility Model Content

[0007] The purpose of the present invention is to provide a carton connection structure to solve the problems raised in the above background technology.

The edge panels and the middle panels are both arranged in a rectangular or square structure. The cutting board also comprises two sealing panels, which are arranged on different sides of the edge panels at the head and tail ends. Horizontal folds are provided between the edge panels and the middle panels and between adjacent middle panels, and vertical folds are provided between the edge panels and the sealing panels.

[0012] Furthermore, the joints between the two edge panels and the joints between the cover panel and the edge panels or the middle panels are bonded with glue, tape or nails.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1 to 5 A carton connection structure includes a cutting board 1, which is cut from a whole piece of paper board. The cutting board 1 includes two edge panels 2 arranged at the head and tail ends and one or more middle panels 4 arranged between the two edge panels 2. The edge panels 2 and the middle panels 4 are both arranged in a rectangular or square structure. The cutting board 1 also includes two sealing panels 6, which are arranged on different sides of the edge panels 2 at the head and tail ends. Horizontal folds 3 are provided between the edge panels 2 and the middle panels 4 and between adjacent middle panels 4, and vertical folds 5 are provided between the edge panels 2 and the sealing panels 6.

[0026] Working principle of this embodiment:

[0027] In this embodiment, a cutting paper plate 1 including two edge panels 2, one or more middle panels 4 and two cover panels 6 is cut out from a whole piece of cardboard through a precise cutting process. Figure 5 As shown, the maximum utilization of the paperboard can be achieved. Depending on the number of intermediate panels 4, it can be spliced ​​into multiple prism structures such as triangular prisms and quadrangular prisms. Then, on the cut paperboard 1, transverse folds 3 are preset between the edge panels 2 and the intermediate panels 4, as well as between adjacent intermediate panels 4; these transverse folds allow the panels to be folded in a specific direction during assembly to form the side walls of the carton; at the same time, vertical folds 5 are provided between the edge panels 2 and the closing panels 6, so that the closing panels can be folded vertically and close the two ends of the carton. During assembly, the edge panels 2 and the intermediate panels 4 are folded into the side walls of the carton according to the transverse folds 3 to form a preliminary box structure; then, the closing panels 6 are folded and fixed to the edge panels 2 at the head and tail ends using the vertical folds 5 to complete the closure of the carton.

[0028] This embodiment can reduce the use of cardboard and the generation of waste. The standardized cutting and folding design makes the carton production process more suitable for automated production lines. Depending on the number of middle panels 4, they can be spliced ​​into triangular prisms, quadrangular prisms and other multi-prism structures.

[0030] In this embodiment, the reinforcement frame 7 effectively improves the structural strength of the carton without significantly increasing the amount of cardboard used.

[0031] Example 3: Please refer to Figures 1 to 4 , a carton connection structure, which differs from Example 2 in that a shrinkage gap 8 is provided between the outer edge of the reinforcement frame 7 and the edge of the middle enclosure 4 or the edge enclosure 2 or the sealing plate 6.

[0032] In this embodiment, the shrinkage gap 8 is used to prevent interference between the reinforcement frame 7 and the cut paper plate 1 during assembly.

[0033] Example 4: Please refer to Figure 3 , a carton connection structure, which differs from Example 1 in that the joints of the two edge panels 2 and the joints of the closing plate 6 and the edge panels 2 or the middle panel 4 are bonded with glue, tape or nails.

[0034] In this embodiment, the cutting paper plate 1 can adopt a process connection mode, which can be flexibly selected according to actual conditions.

[0035] Example 5: Please refer to Figures 1-2 , a carton connection structure, which differs from Example 1 in that the reinforcement frame 7 is made of corrugated paper or hard plastic.

[0036] In this embodiment, the reinforcement frame 7 can be made of corrugated paper or hard plastic. Corrugated paper has lower cost, while hard plastic has higher structural strength and lower thickness.
