Abstract

The utility model discloses a double-pit paperboard. The double-pit paperboard comprises surface paper, middle paper and inner paper, wherein the middle paper is positioned between the surface paper and the inner paper; a layer of core paper is arranged between the surface paper and the middle paper, and the other layer of core paper is arranged between the middle paper and the inner paper; the radial section of the core paper can be waveform-shaped or triangular or trapezoid-tooth shaped; and the two layers of core paper are mutually crossed in an X shape.

Description

A kind of two holes cardboard

Technical field

These novel a kind of cardboard, espespecially a kind of five layer paperboards that two holes are arranged of relating to.

Background technology

General carton is all formed by folding cardboard, and carton is in order to packing and storing, transportation article, and carton exists inseparable relation with daily life.Yet most corrugated board all is by a facial tissue, inner paper and intermediate layer, and the intermediate layer is established and stopped as core paper or fill that other material makes, it is simple in structure, and the carton of therefore making is storing, when transporting article, can not play resistance to compression, shock proof effect makes article damage easily; If the papery of surface layer is thinner, when being folded into carton, very easily break.

In addition because the lines of the core paper that arranges only has a kind of direction, therefore, cardboard when being subject to external force, easily bending; When cutting because being subject to the directionality restriction of refill, and so that quantity in stock increase.

The utility model content

The technical problems to be solved in the utility model is for above-mentioned deficiency of the prior art, and a kind of two holes cardboard is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme to realize: a kind of two holes cardboard, and include facial tissue, middle paper and inner paper and form, it is characterized in that: described middle paper is between between facial tissue and inner paper;

Between described facial tissue and middle paper, be provided with altogether two layers of core paper between middle paper and inner paper;

Described core paper radial section can be waveform or triangle or trapezoidal dentation;

Described two layers of core paper intersect mutually to be fixed with middle paper, and two layers of core paper are mutually X-shaped.

The beneficial effects of the utility model are: after folding cardboard becomes a carton, no matter this carton is end face or bottom surface, after cardboard inwardly folds, two-layer core paper still can keep cross shaped head, and front and unilateral copulation place in carton form the turning point, therefore can increase substantially the resistance to compression of carton, anti-press capacity, also be not easy to produce fracture because folding.

Also have, better because of its structural strength, its edge is not vulnerable to the collision of foreign object and bending can make the chromatography of printing quite accurate when chromaticity printing when printing.And when cutting cardboard, because not having directionality, but the inventory reduction amount.

The specific embodiment

Below in conjunction with specific embodiment the technical solution of the utility model is described in detail.

As shown in Figure 1 and Figure 2, a kind of two holes cardboards include facial tissue 1, middle paper 2 and inner paper 3 and form, and middle paper 2 is between 3 on facial tissue 1 and inner paper.

2 on facial tissue 1 and middle paper,

middle paper

2 and 3 on inner paper are provided with two layers of

core paper

41,42 altogether.

Core paper

41,42 radial sections can be waveform or triangle or trapezoidal dentation.

Two layers of

core paper

41,42 intersects with middle paper 2 fixing mutually, and two layers of

core paper

41,42 is mutually X-shaped.

The above only is the utility model preferred embodiments, and every any trickle modification, equivalent variations and modification of above embodiment being done according to the technical solution of the utility model all belongs in the scope of technical solutions of the utility model.

Claims

1. two holes cardboard includes facial tissue, middle paper and inner paper and forms, and it is characterized in that: described middle paper is between between facial tissue and inner paper.

2. two holes according to claim 1 cardboard is characterized in that: between described facial tissue and middle paper, be provided with altogether two layers of core paper between middle paper and inner paper.

3. cheat cardboard for according to claim 2 pair, it is characterized in that: described core paper radial section can be waveform or triangle or trapezoidal dentation.

4. cheat cardboard for according to claim 2 pair, it is characterized in that: described two layers of core paper intersect mutually to be fixed with middle paper, and two layers of core paper become X-shaped.
