The technical scheme of the utility model is as follows:
the utility model provides a compound corrugated container board of high strength, includes the bottom plate and connects the curb plate in bottom plate week side, bottom plate and curb plate all include the facial tissue of sandwich paper and compound in the sandwich paper outside, the stupefied height of sandwich paper of bottom plate is greater than the stupefied height of sandwich paper of curb plate, just the facial tissue of bottom plate and curb plate links to each other and forms the indent transition portion and is used for forming the crease.
Furthermore, a fabric interlayer is compounded in the surface paper.
Furthermore, filling materials are filled at the position of the sandwich paper corresponding to the concave transition part.
Further, the filling material is die cutting waste.
Further, the surface of the facial tissue is coated with a film.
Furthermore, the bottom plate and the side plate comprise double-layer sandwich paper, and the middle parts of the bottom plate and the side plate are compounded with the same surface paper.
The carton using the corrugated board comprises the bottom board and the side boards connected to the periphery of the bottom board, and the inward concave transition at the joint of the bottom board and the side boards forms a crease of the carton.
Furthermore, slots are formed in the end sides, close to the side plates, of the bottom plate, and supporting plates capable of being bent downwards in an inclined mode and inserted into the slots are arranged at the bottoms of the side plates corresponding to the slots.
The utility model has the following beneficial effects: the height of the sandwich paper ridges of the bottom plate is greater than that of the sandwich paper ridges of the side plates, and the surface paper of the bottom plate and the surface paper of the side plates are connected to form a concave transition part for forming a crease, so that the surface paper can be adaptively increased so as to be bent; after the die cutting forms the carton board, the bending part is sunken due to the existence, and the facial tissue is suitable for increasing simultaneously, when guaranteeing the cardboard wholeness, can fully guarantee holistic intensity, can not influence intensity because of fluting or indentation back.

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.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
Referring to fig. 1, a compound corrugated container board of high strength, includes bottom plate 1 and connects curb plate 2 in bottom plate week side, bottom plate 1 and curb plate 2 all include the facial tissue of sandwich paper and compound in the sandwich paper inside and outside, the stupefied height of sandwich paper of bottom plate 1 is greater than the stupefied height of sandwich paper of curb plate 2, just bottom plate 1 and curb plate 2's facial tissue link to each other and form indent transition portion and are used for forming crease 3, can make the increase of facial tissue adaptability to buckle. The sandwich paper ridge of the bottom plate 1 is higher, so that the buffer capacity is better.
In order to increase the tear strength of the surface paper, a fabric interlayer 4 is compounded inside the surface paper, namely the surface paper adopts a plurality of paper composite fabrics.
In addition, in order to increase the strength of the bending part, the filling material 5 is filled at the position of the sandwich paper corresponding to the concave transition part 3, and the filling material 5 can adopt (strip-shaped) die cutting waste materials of the plate materials.
In this embodiment, the core paper is only one layer; in order to increase the waterproof performance, the surface of the face paper is coated with a film.
Referring to fig. 2, the bottom plate 1 and the side plate 2 include double-layer sandwich paper, and the middle parts of the bottom plate 1 and the side plate 2 are compounded with the same surface paper to ensure the integrity of the paperboard.
With further reference to fig. 3-4, a carton using the corrugated board is disclosed, which comprises the bottom board 1 and the side boards 2 connected to the periphery of the bottom board 1, wherein the concave transition at the joint of the bottom board 1 and the side boards 2 forms the crease 3 of the carton.
In order to increase the strength of the carton, slots 6 are formed in the end sides, close to the side plates 2, of the bottom plate 1, and supporting plates 7 which can be bent downwards in an inclined mode and are inserted into the slots 6 are formed in the bottoms, corresponding to the slots 6, of the side plates 2.
After the die cutting forms the carton board, the bending part is sunken due to the existence, and the facial tissue is suitable for increasing simultaneously, when guaranteeing the cardboard wholeness, can fully guarantee holistic intensity, can not influence intensity because of fluting or indentation back.
Because the stupefied height of curb plate is lower relatively, and end compressive strength is higher relatively, sets up backup pad 7, when box side bottom atress, forms the interact of curb plate 2 and bottom plate 1, can increase the impact strength of side to a certain extent, increases the holistic intensity of box.
