2. Description of the Related Art In general, when a packaged object such as a precision instrument or a home appliance is transported in a packaging box, the packaging box and the packaged box are protected from damage such as breakage or failure due to an accident during transportation. A cushioning material is interposed between the package and the package so that the package can be protected against external impact. As a conventional cushioning material used in this way, it is known to use molded paper and molded styrofoam.

FIG. 4 is a vertical sectional view of a conventional package using molded paper as a cushioning material. In the figure, reference numeral 1 denotes an object to be packed, and an upper cushioning material 41 fitted to the upper part of the object to be packed 1 is formed of a thick and strong molded paper such as pulp paper, and the lower surface of the object to be packed 1 is formed on the lower surface. It has a hollow box-shaped shape with a concave part that fits in the upper part. Lower cushioning material 42 fitted to the lower part of packaged object 1
Is made of the same molded paper, has a concave portion on the upper surface to fit into the lower part of the article to be packaged 1, and has a hollow box shape inside. When packing the article 1 to be packed, the lower cushioning material 42 is fitted to the lower part of the article 1 to be packed, and the upper cushioning material 41 is fitted to the upper part of the article 1 to be packed. It is stored inside the box 2 and the lid of the packing box 2 is closed to complete the packing. When a light impact is applied to the packaged product from the outside from the outside, the cushioning material made of molded paper reversibly deforms to buffer the impact load, and a severe impact is applied. In such a case, the shock-absorbing load is cushioned by the irreversible deformation of the cushioning material made of molded paper to protect the article to be packed.

FIG. 5 is a vertical sectional view of a conventional package using styrofoam as a cushioning material. In the figure, reference numeral 1 denotes an article to be packed, and an upper cushioning member 51 fitted to the upper part of the article to be packed 1 is formed in a box shape having a concave portion fitted to the upper part of the article to be packed 1 on the lower surface. Styrofoam. The lower cushioning member 52 fitted to the lower part of the packaged object 1 is a box-shaped styrofoam having a concave portion fitted to the lower part of the packaged object 1 on the upper surface. When packing the article 1 to be packed, the lower cushioning material 52 is fitted to the lower part of the article 1 to be packed, and the upper cushioning material 51 is fitted to the upper part of the article 1 to be packed. It is stored inside the box 2 and the lid of the packing box 2 is closed to complete the packing. The styrofoam cushioning material used in this way has excellent strength such as impact resistance and weight resistance.

[0005]

However, since the conventional cushioning material made of molded paper and molded polystyrene foam forms the paper and polystyrene foam according to the shape of the article to be packed, the used molded paper and molded polystyrene foam are used. It is difficult to re-use the articles having different shapes for packing, and there is a problem of waste of resources and disposal of waste products.

Further, the conventional cushioning material made of molded paper is made of paper and has a hollow inside. Therefore, if the cushioning material is once irreversibly deformed by a heavy impact, the cushioning ability is lost. There is a problem of strength such as impact resistance and weight resistance, which is not suitable for packing a heavy object to be packed.

Further, in the conventional foamed polystyrene cushioning material, the molded polystyrene foam which has been discarded after use is bulky, so that a large storage space is required, and it is difficult to recycle, so that disposal processing is required. However, besides the cost of waste disposal, incineration may cause damage to the furnace and generate harmful gases due to high heat, and landfill may result in non-degradable and bulky treatment. The problem of induction of a shortage of fields arises. Disposal of molded Styrofoam has such waste pollution problems.

The present invention has been made in view of the above-mentioned circumstances, and has a structure in which a granular elastic body such as styrene foam is filled in a paper container to improve strength such as impact resistance and weight resistance. It is an object of the present invention to provide a cushioning material that is excellent and easy to use after use, and a packaging material that includes a cushioning material that fits into an object to be packed and a packing box that can store the cushioning material.

[0009]

According to a first aspect of the present invention, there is provided a cushioning material including a granular elastic body and a paper container capable of filling the granular elastic body.

[0010] A packing material according to a second aspect of the present invention includes a cushioning material to be fitted to an article to be packed, and a packing box capable of accommodating the cushioning material. And a paper container that can be filled with the elastic body.

The cushioning material and the packing material according to the present invention have excellent strength such as impact resistance and weight resistance by using a structure in which a granular elastic body such as styrene foam is filled in a thick and durable molded paper container. Further, by separating the paper container and the granular elastic body after use, the paper container can be recycled or disposed of, and the granular elastic body can be easily stored and reused in a space-saving manner. Therefore, problems regarding waste pollution are unlikely to occur.
