In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a compound packing carton body structure is moulded to paper, includes the bottom plate, both sides all are provided with folding first curb plate around the bottom plate, the left and right sides of bottom plate all is provided with folding second curb plate, just the both ends of first curb plate all are provided with folding ear, the inboard that the upper surface of bottom plate is located first curb plate and second curb plate is provided with support piece.

As a further scheme of the utility model: the bottom plate, the first side plate, the folding lug and the second side plate are of an integrated structure, and the box body is a paper-plastic composite plate.

As a still further scheme of the utility model: the length of the first side plate is longer than that of the second side plate, the length of the first side plate is the same as that of the long edge of the bottom plate, and the length of the second side plate is the same as that of the short edge of the bottom plate.

As a still further scheme of the utility model: it is provided with first crease to roll over between ear and the first curb plate, it is contactless between ear and the second curb plate to roll over, be provided with the second crease between bottom plate and first curb plate and the second curb plate.

As a still further scheme of the utility model: the bottom size of the supporting piece is the same as the size of the bottom plate, and the thickness of the supporting piece is the same as the width of the first side plate.

As a still further scheme of the utility model: the support piece is a foam box, and the support piece is fixedly connected with the first side plate, the second side plate and the folding lug through coating hot melt adhesive.

Compared with the prior art, the utility model has the beneficial effects that:

compared with the paperboard in the prior art, the box body in the utility model has the advantages of less material consumption, production cost saving, simpler manufacturing steps and greatly improved working efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, as shown in fig. 1, a position a in fig. 1 is a long side, a position B is a lifting lug, a position C is a short side, a crease is formed in the middle of the two long sides, folding is required to be performed along the crease, hot melt adhesive is coated in the whole paper box, and then processing is performed on equipment, however, the produced product has a great defect because the folded long sides are not easily attached after being folded, foam is easily extruded, a gap is formed, which causes that subsequent folding is easy and the gap is too large and does not meet the requirements, and meanwhile, one more flanging is performed, so that the cost is high; original product still has a defect to have the hangers to appear for the minor face of original product after the turn-ups, on four angles, needs to fix whole cooperation paper tape through the nail to whole, the comparatively trouble of process of production.

Therefore, the utility model discloses a paper-plastic composite packaging box body structure, as shown in figures 2 to 4, the structure comprises a bottom plate 1, foldable first side plates 2 are arranged on the front side and the rear side of the bottom plate 1, foldable second side plates 3 are arranged on the left side and the right side of the bottom plate 1, foldable folding lugs 4 are arranged at two end parts of the first side plates 2, the bottom plate 1, the first side plates 2, the folding lugs 4 and the second side plates 3 are a box body in an integrated structure, the box body is a paper-plastic composite plate, the length of the first side plates 2 is longer than that of the second side plates 3, the length of the first side plates 2 is the same as that of the long sides of the bottom plate 1, the length of the second side plates 3 is the same as that of the short sides of the bottom plate 1, first folding marks 5 are arranged between the folding lugs 4 and the first side plates 2, and the folding lugs 4 are not in contact with the second side plates 3, be provided with second crease 7 between bottom plate 1 and first curb plate 2 and the second curb plate 3, the inboard that the upper surface of bottom plate 1 is located first curb plate 2 and second curb plate 3 is provided with support piece 6, support piece 6's bottom size is the same with bottom plate 1 size, just support piece 6's thickness is the same with the width of first curb plate 2, support piece 6 is the foam box, just through coating hot melt adhesive fixed connection between support piece 6 and first curb plate 2, second curb plate 3 and the book ear 4.
