[0001]

[Industrial application field] The present invention improves the impact resistance,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard cushioning cushion which can easily cope with a change in the shape of a packaged article.

[0002]

2. Description of the Related Art When packing precision mechanical parts such as electronic products, generally, both sides of a package are sandwiched by shock absorbers to prevent the package from coming into direct contact with the inner wall of a packing box and to prevent vibration during transportation. The shock absorber absorbs shocks and shocks so that the package can be transported safely.

[0003] Styrofoam is known as a buffer of this type. This is a foam block made of styrene in which concave portions corresponding to the shapes of both sides of the package are formed, and is used as a buffer for packing various electronic products due to its buffer effect. There is also a combination of this styrene block and cardboard.

[0004] However, in the case of using this kind of foamed styrene, the styrene is extremely bulky, so that disposal after taking out the package has been troublesome.

[0005] For this reason, a cushion made of a single cardboard has been produced. In this case, the corrugated cardboard is formed by folding a mountain or valley to form a hollow portion, and a fitting concave portion is formed in accordance with the outer shape of the packaged material. This has the advantage that it can be returned to the developed shape, the disposal process can be simplified, and the waste paper can be reused such as collected.

[0006]

However, this type of corrugated cardboard cushion has conventionally been constructed of a single piece of corrugated cardboard and has a hollow portion as a cushioning portion, so that it is structurally stronger than the styrene block. Low and poor impact resistance. In order to improve this defect, it is sufficient to partially reinforce using an adhesive means such as an adhesive or staple,
The advantage at the time of disassembly mentioned above is spoiled.

In this type of corrugated cardboard shock absorber, it is necessary to devise the design of the fitting portion for each shape of the package to be inserted, or to design the whole into a predicted expanded shape according to the folded shape. However, the design and mold change were extremely troublesome.

The present invention has been made to solve the above problems, and has as its object to improve the overall strength and impact resistance without using an adhesive means, and to easily cope with a change in the shape of a package. It is intended to provide a cushioning material for packaging.

[0009]

In order to achieve the above object, according to the present invention, both sides of a package are sandwiched between a pair of cardboard cushions, and the package is loaded together with the buffers into a packing box. The cushioning body for packing as described above, wherein the cushioning body has a pair of hollow legs abutting against the inner side wall of the packing box with one corrugated cardboard bent into a concave cross section and supporting the concave bottom surface. A concave member having, a single piece of corrugated cardboard is bent into a U-shaped cross section and fitted into the concave inside of the concave member flush, and is inserted into the hollow inside of the leg at the fitting end side. And a pair of insert members formed integrally with each other by projecting a pair of insertion pieces and forming a notch on the surface side of the insertion piece corresponding to the outer shape of the package.

[0010]

According to the above construction, the concave member can be set to a simple shape in consideration of strength and impact resistance. When the shape of the package is changed, the fitting hole shape of the mounting member can be set to a simple shape in consideration of the strength and impact resistance of the package outer concave member. When the shape of the package is changed, the shape of the fitting hole of the mounting member may be changed according to the outer shape of the package, and the original concave member can be used as it is.
