Paperboard inserted and connected environment-friendly packaging box

Abstract

The invention discloses a paperboard inserted and connected environment-friendly packaging box, and relates to the field of packaging boxes. The paperboard inserted and connected environment-friendlypackaging box comprises a first paperboard and a second paperboard which are of a rectangular structure, the first paperboard is divided into a first bottom plate and two first side plates located onthe two sides of the first bottom plate through folding lines, and a first self-locking inserting buckle is arranged on the outer side of one first side plate; an inserting tongue is arranged on the outer side of the other first side plate; the second paperboard is divided into a second bottom plate and two second side plates located on the two sides of the second paperboard through fold lines, and second self-locking inserting buckles are arranged on the outer sides of the two second side plates; the two ends of the first bottom plate, the two ends of each first side plate, the two ends of the second bottom plate and the two ends of each second side plate are provided with protective wings through folding lines correspondingly, and second self-locking type inserting buckle holes are formed in the protective wings of the first bottom plate; and a first self-locking type inserting buckle hole is formed in the protective wing at one end of the second bottom plate, and an inserting tonguehole is formed in the protective wing at the other end of the second bottom plate. The paperboard inserted and connected environment-friendly packaging box is safe, environmentally friendly and suitable for manufacturing paper box packages with large box body areas.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to a cardboard plug-in environment-friendly packaging box. Background technique [0002] In the field of packaging, common carton forming processes include folding cartons, glued cartons and plug-in cartons. Folding cartons are suitable for cartons with a small body area. The paper is folded instead of glued and molded, and the production process is environmentally friendly. However, when the box body has a large area, requires high load-bearing, and is formed with thicker paper such as corrugated paper, the folding process is inconvenient to use. Adhesive cartons rely on adhesives to bond the extended part of the box body (paste head) to the box body. This type of carton has almost no part that is cut off and wasted in the net area, so it is more material-saving, but the use of adhesives for forming The process is not environmentally friendly. Although there are many rela...

Problems solved by technology

The standard size paper available in the domestic market, the full size is 787*1092mm, the large size paper is slightly larger, the full size is 889*1194, the acid-free corrugated paper imported from Japan, the maximum size is only 850* 1300mm, such a format length, has a great limit on the volume of the packaging box, and it is impossible to make a larger lock-type carton

The inventor once applied for a utility model patent "A non-adhesive plug-in cultural relic acid-free packaging box", figure 2 and image 3 They are the version of the utility model and the structure after forming. This method does not use any adhesive, and the production process is environmentally friendly. The load-bearing capacity and durability of the formed carton are also good, but it consumes more paper. Parts A and D More materials are cut and wasted outside the net area, and the structure of the paper pattern is complex, making design calculation and processing difficult
