Abstract

The utility model discloses a hollow paper board which comprises an upper-layer paper board and a lower-layer paper board, wherein a middle layer is arranged between the upper-layer paper board and the lower-layer paper board; the middle layer is a paper core; the paper core can be in a waveform shape, triangle shape or elliptic tooth shape; and the middle layer, the upper-layer paper board and the lower-layer paper board are fixed together. The paper board has the characteristics of simple structure, low manufacturing cost and no pollution, and shake and breakage prevention can be effectively achieved.

Description

A kind of Hollow paper board

Technical field

This novel a kind of cardboard, espespecially a kind of Hollow paper board of relating to.

Background technology

Cardboard, carton use quite extensive in life, due to different other the wooden or metal blanks of cardboard, store and transportation in, easily destroyed, thus need the large cardboard of thickness, or in cardboard filling some do blanket and protect interior items.Generally adopt in cardboard filling sponge or wrap up with the plastic foil of bubble, but owing to adopting widely plastic material, having caused in use the pollution to environment, if increase the thickness of cardboard, increasing again manufacturing cost.

The utility model content

The technical problems to be solved in the utility model is for above-mentioned deficiency of the prior art, but the Hollow paper board of the anti-folding of a kind of effective shock is provided.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of have upper strata cardboard and a lower layer paperboard, it is characterized in that, described upper strata cardboard and lower layer paperboard are provided with an intermediate layer, and described intermediate layer and upper strata cardboard, lower layer paperboard are fixed;

The radial section undulate in described intermediate layer;

The radial section in described intermediate layer is triangular in shape;

The radial section in described intermediate layer is trapezoidal dentation;

Described intermediate layer is refill.

Owing to taking technique scheme, the utility model arranges one deck intermediate layer in the cavity of two-layer cardboard, be used for shockproof anti-folding, relative prior art, the utlity model has simple in structure, cheap and free of contamination advantage, and convenient and practical, but the anti-folding of effective shock.

Description of drawings

Fig. 1 is the radial section view of this Novel paperboard;

Fig. 2 is the another kind of radial section view of this Novel paperboard;

The another kind of radial section view of Fig. 3 written or printed documents Novel paperboard.

Wherein: 1, upper strata cardboard;

2, intermediate layer;

3, lower layer paperboard.

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, a kind of Hollow paper board, consisted of by upper strata cardboard 1, lower layer paperboard 3 and the intermediate level, described intermediate layer 2 is refill, the radial section in intermediate layer 2 is continuous waveform, intermediate layer 3 is fixed with upper strata cardboard 1, lower layer paperboard 2, so because the intermediate layer undulate has elastic characteristic, can play cushioning effect when being squeezed.

As shown in Figure 2, described intermediate layer 2 radial sections are continuous triangle.

As shown in Figure 3, described intermediate layer 2 radial sections are continuous trapezoidal dentation.

As Fig. 1, Fig. 2, shown in Figure 3, described intermediate layer 2 is refill.

Owing to there being certain space between upper and lower layer paperboard, can hold the intermediate layer on the one hand, maintain a certain distance with the intermediate layer on the other hand, therefore can play the effect of shockproof anti-folding in use.

The above is only the utility model better embodiment, 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. a Hollow paper board, include upper strata cardboard and lower layer paperboard, and described upper strata cardboard and lower layer paperboard are provided with an intermediate layer, and described intermediate layer and upper strata cardboard, lower layer paperboard are fixed, and it is characterized in that, the radial section in described intermediate layer is trapezoidal dentation.

2. cardboard according to claim 1, is characterized in that, the radial section undulate in described intermediate layer.

3. cardboard according to claim 1, is characterized in that, the radial section in described intermediate layer is triangular in shape.
