Abstract

PROBLEM TO BE SOLVED: To provide a product protection material made of cardboard in a form of plate or its deformation-worked shape arranged at an upper segment, a lower segment or both sides of the product such as a fruit and the like stored mainly in a packaging box such as a cardboard box or the like, wherein the product protection material is suitable for protecting a product easily damaged and further adapted for reducing an amount of dusts while being recycled in a less-expensive manner. SOLUTION: This protection material is comprised of five-layer structure of a rear liner 6 and a core 5 constituting a one-surface cardboard composing segment of step A; and a middle liner 4, a core 3 and a front liner 2 constituting both-surface cardboard composing segment of step B. This is characterized in that at least the rear liner 6 and the core 5 of the composing segment of step A is made of craft paper or a thin paper other than the cardboard thick paper.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard product protection material, and more particularly, to boxing of fruits and vegetables such as pears, persimmons, apples, and industrial products that are easily damaged. The present invention relates to an inserted plate shape or a corrugated product protection material formed by processing and deforming the shape.

[0002]

2. Description of the Related Art For example, fruits such as pears, persimmons, and apples are stored in a pack material having a plurality of storage recesses arranged side by side and packed in a cardboard case in one or more stages. At that time, a plate-shaped commodity protection material is arranged on the upper side of the fruit so as not to damage the fruit. Conventionally used packing materials and commodity protection materials are often made of resin.

[0003] In recent years, however, waste reduction and recycling have been promoted for resource protection and environmental safety, and it has become necessary to consider shipping materials for fruits and vegetables. Under these circumstances, it has been considered to use paper materials that can be easily recycled instead of resin materials.

[0004] From such a point of view, a protective material in which two single-faced cardboards are stacked as shown in FIG. 5 has been proposed. FIG.
FIG. 5 (A) shows two single-sided cardboards stacked in the same direction, FIG. 5 (B) shows two single-sided cardboards stacked with their cores facing each other, and FIG. C)
1 shows two single-sided corrugated boards stacked in a crossed state.

[0005]

Since each of these conventional protective materials is formed by laminating two single-sided cardboards, it requires two steps of a single-sided cardboard manufacturing process and a bonding process.
The manufacturing cost increases accordingly. In addition, two single-faced cardboards are often of the same type and made of the same material, and there is a problem in that the use of cardboard having cushioning properties causes a problem in strength, and the use of cardboard having strength results in lack of cushioning properties.

Accordingly, the present invention provides a plate-like protective material mainly disposed on the upper and lower sides of a product such as a fruit housed in a packaging box such as a cardboard box, and has appropriate strength and cushioning property. It is another object of the present invention to provide a cardboard product protection material which is also provided and is suitable for protecting easily damaged products, and which can be regenerated at low cost and contributes to the reduction of waste.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a back liner and a core constituting a single-sided corrugated cardboard component of A type, and a middle liner, a center and a front liner constituting a double-sided corrugated cardboard component of B type. The above object has been solved by a cardboard product protection material having a five-layer structure, wherein at least the back liner and the core of the A-stage type component are made of thin paper other than kraft paper or cardboard base paper.

[0008]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing the structure of a cardboard product protection material 1 according to the present invention. The front liner 2 constitutes a double-sided corrugated cardboard component of the B-stage type, the center core 3 and the middle liner 4, and A The core 5 and the back liner 6 constituting the single-sided cardboard component of the corrugated type are laminated in this order.
Among these constituent paper materials, at least the core 5 and the back liner 6 are made of thin paper other than kraft paper or corrugated cardboard.

FIG. 2 shows a method of manufacturing the protective material 1. Paper rolls for respective layers are juxtaposed, simultaneously fed out, and laminated and adhered on one line. Has been done).

As shown in FIG. 3, for example, the protective material 1 according to the present invention is housed in a pack material 9 in a cardboard case 8 and is stacked flat, or a stacked product such as fruits.
The product 10 is placed on top of the product 0 so that the back liner 6 side contacts the upper surface of the product 10.

In this case, since the protective material 1 is made of thin paper other than kraft paper or corrugated cardboard on the product contact side of the protective material 1 and has an A-stage configuration weaker in strength than the upper B-stage configuration, When a load is applied to the core 1, the core 5 is crushed, and the upper part of the product 10 enters the core 5 (see FIG. 4). Thereby, the movement of the product 10 is stopped during transportation or the like, and the product 10 is hardly damaged because the product contact surface is made of soft kraft paper. The strength of the protective material 1 itself is ensured by the upper B-stage components 2 to 4.

[0012]

The present invention is as described above. The cardboard product protection material according to the present invention is not only easy to manufacture and can be reproduced at low cost, but also has an appropriate cushioning property and strength, and Has the effect of being able to sufficiently protect.
