[0002]

2. Description of the Related Art In recent years, packaging materials have been strongly demanded to be resource-saving and easy to reuse as a measure for global environmental protection. However, it is the actual situation that styrofoam, which still presents a problem in the disposal process as a cushioning material, is mainly used.

The conventional cushioning device for packaging will be described below. FIG. 3 shows a vertical cross section of a main part of a conventional cushioning device for a washing machine. In FIG. 3, 1 is an outer box of the washing machine, and 2 is a cover attached to the upper end opening of the outer box 1. Reference numeral 3 denotes a shock absorber that is integrally formed of expanded polystyrene arranged above the cover 2. Reference numeral 4 denotes a packaging box, and S denotes an inner dimension of the packaging box. The shape of the cover 2 of the washing machine is downward, and has a dimension h between itself and the central portion.

As shown in FIG. 4, the cushioning material 3 is mounted on the left and right sides of the cover 2 while being mounted thereon, and at the same time, the cushioning material is supported in a cushioned manner while preventing the swinging of the washing machine.

[0005]

However, in the above-mentioned conventional configuration, the cushioning body 3 integrally formed of styrofoam so as to fit into the shape of the cover 2 of the washing machine has a large volume and is suitable for storage during packaging work. However, it requires a lot of storage space, and it is unreasonable to store and transport the waste after use because it is bulky.

[0006] Further, although it is possible to recycle the Styrofoam, it involves quality problems such as mixing of dust and the like adhering due to the action of static electricity, mixing of those whose strength has deteriorated due to aging, and further recycling. However, there is a problem that it is not easy at present to recycle the waste because it requires recovery, recycling equipment, recycling technology, etc.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a packaging cushioning device made of corrugated cardboard, which is effective with a small amount of material and is easy to reuse.

[0008]

In order to achieve this object, the packaging cushioning device of the present invention is a cushioning device for a washing machine, wherein the front side of the upper part of the washing machine is shaped such that the front side is lower than the central part. The material is made of corrugated board, and this corrugated board is formed by forming a plurality of folded-back portions on the front side according to the dimensional difference between the central portion and the front side and bending it so as to wrap it.

[0009]

With this structure, the cushioning material made of corrugated board absorbs a dimensional difference from the front side of the cover of the washing machine at the folded portion, and the folded upper surface portion is folded in such a manner that the folded portion is sized in the height direction. Can be packaged at almost the same height on the front side and the rear side, and in addition, the folded corrugated cardboard surfaces are laminated against the impact force generated when handling the package, etc. can do.

Further, the corrugated cardboard is also bent at the side surface of the upper part of the washing machine and the fitting portions located at the front and rear so that the folding surfaces are parallel to each other. Similarly, the washing machine can be fixed as a cushion.

As described above, the cushioning body formed by folding and assembling corrugated cardboard, which is more rigid than Styrofoam, can reduce the amount of material used and can be disassembled into one sheet after use. It can be said that it is easy to use.
