Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cushioning material.

[0002]

[Prior Art]

 Conventionally, when a product is stored in a cardboard box, it has been customary to use a cushioning material made of Styrofoam molded into a shape matching the outer shape of the product.

[0003]

[Problems to be solved by the device]

 Such a conventional cushioning material has to be made in conformity with the shape and dimensions of the product and the corrugated cardboard containing the product and is not versatile. Further, since the conventional cushioning material is styrofoam, it has a high incineration temperature and produces a toxic gas during incineration, so there is a problem in its disposal.

In view of the above points, the present invention is intended to propose a cushioning material that is versatile and has no problem of disposal.

[0005]

[Means for Solving the Problems]

 The cushioning material 1 according to the present invention is integrally molded so that a plurality of cushioning units 2, 2, ..., Each having a bulge 3 formed on a part of a flat plate are connected through a groove-like connecting portion 5. Composed of pulp moldings.

In addition, the cushioning material 1 according to the present invention comprises a plurality of cushioning units 2, 2, in which a plurality of bulges 3, 3, ... ...... is composed of a pulp molded body integrally molded so as to be connected through the groove-shaped connecting portion 5.

In the cushioning material 1 according to the present invention, a plurality of bulging portions 3 having the same shape and the same size are formed on a part of the flat plate, and the plurality of bulging portions 3 of the flat plate are formed. A plurality of buffer units 2 each having a concave portion 4 formed on the surface opposite to the plurality of bulging portions 3 and 3 surrounded by 3 ... It is made of a single-piece molded pulp body.

Further, the cushioning material 1 according to the present invention is constructed such that a plurality of cushioning units 2 each having a bulge 3 formed on a part of a flat plate are coupled to each other through a coupling portion 5 composed of a plurality of grooves. It consists of a molded pulp molding.

[0009]

[Action]

 The cushioning material 1 according to the present invention is separated as it is or at the groove-shaped connecting portion 5 by a cutter, scissors or the like into a cushioning material composed of one or a plurality of cushioning units 2, for example, a product is a box. When it is stored in the box, it is bent around the groove-shaped connecting portion 5 as necessary to be interposed between the product and the box. 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. Since not only the bulging portion 3 but also the recessed portion 4 is deformed, the cushioning effect is greater than in the case where the recessed portion 4 is not provided.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. FIG. 1 is a cross-sectional view of a cushioning material 1 of an embodiment, and FIGS. 2 and 3 are a front view and a back view of the cushioning material 1 viewed from above and below in the cross-sectional view of FIG. 1, respectively.

The cushioning material 1 is formed so that four bulged portions 3, 3 ... Having the same shape and the same size and having a circular cross section are located at apexes of a square or a rectangle on a part of a flat plate. The flat plate is surrounded by the four bulging portions 3, 3 ... 8 and the concave portion 4 is formed on the surface opposite to the four bulging portions 3, 3. (4 × 2) buffer units 2, 2, ... Are made of integrally molded pulp molded bodies so as to be connected through the groove-shaped connecting portions 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 can be 1, 2, 3, 5 or more, and the shape thereof is also arbitrary.

The groove-shaped connecting portion 5 serves as a bent portion when a plurality of shock absorbing units 2 are connected, and separates the shock absorbing material 1 into a shock absorbing material composed of one or a plurality of shock absorbing units 2. It becomes the cutting part of. When a plurality of grooves are formed in the groove-shaped connecting portion 5 as shown in FIG. 4, the bending of those portions becomes easy.

As shown in FIG. 5, when 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, When a load 8 is applied to the cushioning material 1, a strain 9 is generated in the cushioning material 1, and when the load 8 is considerably large, the bulging portion 3 is deformed so as to be collapsed as shown in FIG. The recess 4 is also deformed so as to be crushed. The cushioning material 1 exerts a cushioning function by the deformation of the bulging portion 3 and the recessed portion 4.

The cushioning material 1 may be used as it is or may be separated into cushioning materials composed of one or a plurality of cushioning units 2 and may be provided along the outer periphery of the product as shown in FIGS. Then, the product is stored in a cardboard box or the like.

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

Since the cushioning material 1 is made of pulp, it is easy to incinerate, and unnecessary material can be collected and reused.

[0019]

[Effect of the device]

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