[Detailed description of the device]

[0001]

This invention relates to a cushioning material.

[0002]

2. Description of the Related Art Conventionally, when storing a product in a cardboard box,
It has been customary to use a cushioning material made of Styrofoam molded into the shape of the product.

[0003]

Such a conventional cushioning material is not versatile because it must be made in accordance with the shape and dimensions of the product and the corrugated board in which it is stored. Further, since the conventional cushioning material is styrofoam, the incineration temperature is high, and a toxic gas is generated during incineration, so there is a problem in its disposal.

In view of this point, the present invention has versatility ,
The purpose of the present invention is to propose a cushioning material that has a great cushioning effect and does not cause a problem in waste disposal.

[0005]

[Means for Solving the Problems] Buffer material 1 according to the present invention
Has a plurality of bulges 3 formed on a part of the back surface of the flat plate.
And is surrounded by the plurality of bulging portions 3 on the surface of the flat plate.
A plurality of recesses 4 are formed at positions corresponding to the recessed portions.
This cushioning units 2,2, ......... is composed of integrally molded pulp molded as is connected through a groove-shaped connecting part 5
And are characterized .

Further, the cushioning material 1 according to the present invention is a back surface of a flat plate.
The plurality of bulging portions 3 formed in a part of the
And the same size .

[0007]

The cushioning material 1 according to the present invention is, as it is, or separated by a cutter, scissors or the like at the groove-like connecting portion 5 to be separated into a cushioning material composed of one or a plurality of cushioning units 2, for example, a product. When storing the product in a box, if necessary, bend at the groove-shaped connecting portion 5 to form the bulging portion 3.
The side opposite the marked side, that is, the front side of the flat plate, toward the product
Allowed to interposed between the product and the box Te. When an impact is applied from the outside of the box, the bulging portion 3 is deformed and absorbs the impact, and the impact does not reach the product. Moreover, the above-mentioned expansion of the back surface of the flat plate
A recess 4 is formed at a position corresponding to the portion surrounded by the protrusion 3.
If there is a big impact,
Since the recessed portion 4 also deforms and absorbs the shock, the buffering effect is greater than that in the case where the recessed portion 4 is not provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a cross-sectional view of a cushioning material 1 of the present invention, and FIGS. 2 and 3 are a front view and a back view as seen from above and below, respectively, in the cross-sectional view of FIG.

The cushioning material 1 has four swelling portions 3, 3 ... Having the same shape and the same size and a circular cross section located on a part of the back surface of the flat plate at the apexes of a square or a rectangle. formed Rutotomoni, on the back surface of the flat plate the four bulging portions
Recessed part 4 at a position corresponding to the part surrounded by 3, 3 ...
There eight buffer units 2, 2 are formed, ......... is there it consists pulp molded body integrally formed as being connected through a groove-shaped connecting part 5.

The pulp molded body is made from waste paper as a raw material and molded (papermaking) using a mold.

The number of the cushioning units 2 constituting the cushioning material 1 is arbitrary as long as it is two or more. Further, the number of the bulging portions 3 of the buffer unit 2 may be plural, and is not limited to four.
Alternatively, two, three, five or more pieces are possible, and the shape thereof is arbitrary.

The groove-shaped connecting portion 5 serves as a bent portion when a plurality of buffer units 2 are connected, and the buffer material 1
Serves as a cutting portion for separating the cushioning material into one or a plurality of cushioning units 2. In this groove-shaped connecting portion 5, FIG.
When a plurality of grooves are formed as described above, it is easy to bend that portion.

As shown in FIG. 5, the cushioning material 1 is placed on the floor 9 so that the bulging portion 3 is in contact with the floor 6, and the product 7 is placed on the cushioning material 1, that is , on the surface of a flat plate. When you place
When a load of 8 is applied to the cushioning material 1, the cushioning material 1 is distorted 9
When the load 8 is considerably large, the bulging portion 3 is deformed so as to be crushed as shown in FIG. 6, and the recessed portion 4 is also deformed so as to be crushed. Due to the deformation of the bulging portion 3 and the concave portion 4, the cushioning material 1 exerts a large cushioning function.

The cushioning material 1 may be used as it is or may be separated into a cushioning material composed of one or a plurality of cushioning units 2.
As shown in FIG. 7 and FIG. 8, the product is housed in a cardboard box or the like along the outer peripheral surface of the product or by being bonded.

A waterproof coating may be applied to the surface of the cushioning material 1.

Since this cushioning material 1 is made of pulp, it is easy to incinerate, and the unnecessary material is recovered,
Can be reused.

[0017]

According to the present invention described above, it is possible to obtain a cushioning material which is versatile, has a large cushioning effect, and has no problem of disposal.
