Description of the Related Art Generally, when packing articles such as electric equipment, machine parts and glass products in a corrugated cardboard box or the like, a cushioning material is provided between the corrugated cardboard box and the article so as not to be damaged during transportation. I am trying to do it.

As such a cushioning material for packaging, a partition plate made of expanded polystyrene resin or thick cardboard has been conventionally used. In the case of the Styrofoam resin, the shape and size of the article to be packed is injection-molded by a mold, and in the case of a partition plate, the shape and size of the article are used. As many cardboards as necessary are assembled and used.

[0004]

However, in the conventional cushioning material using the polystyrene foam resin or the partition plate described above,
There are the following problems.

The styrofoam resin requires various types of dies corresponding to the shape and size of the articles to be packed, which increases the manufacturing cost. It has also been pointed out that when used styrene resin is disposed of by incineration or the like, it causes pollution. Further, there is a problem that it cannot be reused for packing products of different shapes.

Further, in the case of the above-mentioned partition plate, for example, when packing a product having a large number of parts, a large number of partition plates are required, so that it is troublesome to assemble the product or to put the product in and out, which results in workability. bad. Further, the above cardboard has a problem that it has a low absorbency against impact force.

The present invention has been made in view of the above conventional circumstances, and can be commonly used for articles having different shapes and sizes, can be reused, and has a problem of pollution while reducing the manufacturing cost. It is an object of the present invention to provide a packaging cushioning material having a novel structure that can solve the above problems, improve workability during assembly, and improve absorption of impact force.

[0008]

Therefore, the invention of claim 1 is characterized in that an outer bag formed into a predetermined shape and size is filled with paper cotton formed by diffusing paper material into a fibrous shape. It is a cushioning material for packaging. The invention of claim 2 is characterized in that the outer bag is formed with a large number of through holes communicating with the cotton wool.

In order to produce the paper cotton of the present invention, a paper material such as sheep paper, Japanese paper, or used paper is dipped in water to be appropriately moistened, and the paper material is crushed by a mixer or the like to form fibers. It is also possible to use a method in which the above-mentioned paper material is soaked in a chemical or the like and decomposed into a fibrous form by diffusing it into a shape and then drying it. The paper cotton thus manufactured is filled in the outer bag, and the opening of the outer bag is sealed with an adhesive.

[0010]

According to the packing cushioning material of the present invention, the outer bag is filled with the fibrous diffused paper cotton, so that the paper cotton absorbs the impact force, and the damage during transportation is ensured. Can be prevented. Moreover, the cushioning material of the present invention can be commonly used for various articles having different shapes because the paper cotton is deformed according to the shape of the articles to be packed, and also for various articles having different shapes. It can be reused. Moreover,
The laborious assembly work of the partition plate can be eliminated.

Further, the paper cotton of the present invention can be manufactured by, for example, crushing a moistened paper material, and the cost can be greatly reduced as compared with the conventional manufacturing using many kinds of molds. Further, even if the paper cotton is incinerated, there is no problem of pollution as in the case of the Styrofoam resin. Further, even if it is dumped in the natural world such as forests and rivers, it is easily decomposed into microorganisms and becomes a pollution-free substance.

According to the second aspect of the present invention, the outer bag is formed with a through hole communicating with the paper cotton. Therefore, when a load is applied during packaging or transportation of the article, the through hole of the outer bag causes the inside of the paper cotton to pass through. The air will escape and absorb the above-mentioned load, thereby avoiding the problem that the outer bag is torn.
