Paper box with automatic lock bottom and tuck cover on single cardboard and forming method thereof

Abstract

The invention relates to the technical field of packaging boxes, in particular to a paper box with an automatic lock bottom and a tuck cover on a single cardboard and a forming method thereof. The paper box comprises a tuck cover, a surrounding edge and an automatic lock bottom, the surrounding edge comprises a first side face, a second side face, a third side face and a fourth side face which areconnected end to end, one side of the tuck cover is connected to the first side face, the other side of the tuck cover is connected with the third side face in a clamped mode, the first side face, the second side face, the third side face and the fourth side face are connected with a first lock bottom, a second lock bottom, a third lock bottom and a fourth lock bottom respectively, and the firstlock bottom, the second lock bottom, the third lock bottom and the fourth lock bottom can mutually be in lap joint to form the automatic lock bottom. According to the paper box with the automatic lockbottom and the tuck cover on the single cardboard and the forming method thereof, the tuck cover, the surrounding edge and the automatic lock bottom are machined on the single paperboard, raw material consumption is reduced, the production cost of the paper box is reduced, the advantages of a traditional book-shaped box and an automatic bottom locking box are combined, transportation can be carried out in a folded and flat mode so that the transportation cost of the paper box can be reduced, and automatic bottom locking can be achieved, the use cost of the paper box is reduced, and the use convenience of the paper box is improved.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, more specifically, to a carton with a self-closing bottom flap for a single cardboard and a forming method thereof. Background technique [0002] Due to the convenience of use, the shake-top carton is welcomed by consumers and also favored by carton manufacturers. At present, manufacturers often use the following process engineering in the production of rocker lid cartons: first, print the forming raw cardboard and perform post-press technology, then die-cut the cardboard according to the designed shape, and send the die-cut cardboard into the automatic glue box machine, and finally manually assembled into a three-dimensional carton structure for delivery; the raw cardboard is often covered with paper-wrapped gray boards, and in order to meet the load-bearing requirements, it is necessary to set an intermediate gray board between the layers of paper-wrapped gray boards. However, there ar...

AI Technical Summary

Problems solved by technology

However, there are many defects in the traditional flap carton and the molding method of the flap carton: (1) it needs to be manually assembled into a three-dimensional structure before delivery, the work efficiency is low, and the production cost is high; (2) the three-dimensional structure carton is handed over The storage space is large, and the transportation cost is high; (3) Using the gray board wrapped in tissue paper to set the gray board in the middle as the production raw material is prone to uneven edges and corners, unsightly appearance, lack of squareness and the phenomenon of "bread box", And the cost of raw materials is high
