Slotted carton flap cover folding application method

Technical field

The invention relates to the field of transportation packaging, and in particular to an application method for a product packaging carton bottom plate. BACKGROUND OF THE INVENTION Packaging cartons have been widely used in product packaging, especially foldable packaging cartons, which not only serve as packaging products and protection products, but also are convenient for transportation, economical and environmentally friendly, and with the continuous technicalization of cartons. Development and improvement will be more widely used in the future. In the prior art, the folding carton is generally assembled from a piece of cardboard after being processed by cutting, indentation, etc., and the four frames form the basic frame of the box, extending from the top and the bottom. The four movable cardboard sheets are folded to form a double-layered carton bottom and a cover plate, which are sealed and fixed for use. In the entire box structure, the side panels are only composed of a single layer of cardboard, and there are two layers of cardboard in the bottom and upper cover portions. From this analysis, it is concluded that the weak portion of the carton is on the side. From the perspective of the inner packaging of the product, since the upper and lower sides are bearing surfaces, the manufacturer also attaches great importance to the protection of the upper and lower sides of the product. The inner packaging also increases the load-bearing capacity of the upper and lower parts, which makes it easy to cause carton protection. The unevenness of the upper and lower sides of the package is excessive, resulting in waste, while the side is less susceptible to impact and compression, and the carton itself is also prone to falling apart. In addition, some products have a large packing space, and paper cards or fillers are added in the carton during the packaging process to facilitate the fixing of the product and the protection of the product, thereby causing great waste. SUMMARY OF THE INVENTION The present invention provides a method for folding a slotted carton flap cover. The method utilizes an excess bottom layer after being folded and used as a product spacing or side panel auxiliary support, effectively utilizing resources, and solving the prior art. The technical problem of uneven protection and partial waste of internal products. The technical solution adopted by the present invention to achieve the above object is to provide a method for a slotted carton flap folding application, comprising the following steps: A. On the one-piece carton board which is cut and pressed, the two ends of the side plate of the carton are connected and fixed to form a square box;

B. The upper and lower flaps of the carton are connected to the inside of the carton to form a double-layer cover of the carton, and the two ends of the carton are closed;

C. Fixing the bottom of the carton; the step B can be specifically divided into the following sub-steps: B1. Folding the four flaps to the inside of the carton;

B2. Folding at least one of the flaps in the inner layer along the pre-compressed indentations to form the three-dimensional shape. The flaps folded in the step B2 are two, three or four. From the general carton structure and the general packaging rules of the product, the strength of the top and bottom of the current carton is obviously stronger than that of the side plate. The inner packaging of the product is also stronger than the side of the upper and lower sides, thus causing excess material on the upper and lower sides, while the side The strength of the shaker is lacking. After folding a part of the rocker cover, it is used for the support in the vertical direction, which is beneficial to balance the protection ability of each side of the carton, and can greatly strengthen the side pressure and impact resistance without adding materials. The ability to improve the carton's ability to prevent breakage and extend the life of the carton can greatly improve the safety of the carton. You can fold a flap according to the actual situation and the needs of the product, or you can fold two. After the flap is folded, the following functions can be realized: First, in the step B2, a part of the folded portion of the flap is attached to the inner side of the side panel, and the bottom of the inner portion of the side panel is pressed against the rocker. The cover is not folded up, and the solution can enhance the pressure and impact resistance of the side panels. Secondly, in the step B2, a part of the folded portion of the flap is folded up and stands in a hollow position of the carton. The solution can effectively divide the space in the carton by using the folded flap, and the product or the positioning port is spaced.

广叩三: In the step Β2, the folded portion of the flap is formed into a stepped protrusion in the hollow portion of the carton, and the solution can better position the product having the convex and concave bottom surface, thereby functioning as a fixed product. Save a lot of filler.

The invention adopts the above technical solution, can effectively utilize the excess rocking cover, improve the pressure and impact resistance of the carton without adding auxiliary materials, and can also play the role of positioning and protecting the inner packaging product, and save resources. Reduce packaging costs. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a carton made in accordance with the method of the present invention.
