DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging cushioning material for fixing an article to be packaged inside a packaging box so that the article to be packaged does not interfere with the inner wall of the packaging box. More specifically, while having a leg on the lower surface, a projection on the rear surface
The present invention relates to a packaging cushioning material that fits into a corner of an article to be packaged and holds the article.

[0002]

2. Description of the Related Art When packing articles to be packed in a box, a cushioning material that fits into a corner of the articles to be packed and holds the articles is used to prevent the articles from being damaged by an external impact during transportation. Have been. Conventionally, a polystyrene foam cushioning material has been used as such a cushioning material. The styrofoam cushioning material has advantages that it can be molded into a complicated three-dimensional shape, has excellent cushioning properties, is lightweight, and has a low manufacturing cost. However, Styrofoam generates high temperatures when incinerated and damages the incinerator, so it has to be landfilled in a landfill. However, in recent years, it has become impossible to secure landfill sites, and there has been a problem that it is difficult to dispose of styrene foam having a large volume after use.

[0003] Therefore, a cushioning material made of cardboard has been used. The cardboard cushioning material is manufactured by cutting a required shape from a block in which a plurality of cardboard sheets are laminated and bonded with an adhesive or the like. The cardboard cushioning material can be incinerated after use,
Also, reuse is possible.

[0004]

However, in the cushioning material made of corrugated cardboard, the end face of the corrugated paper is exposed on the cut-out surface, as is apparent from the manufacturing method. The end face is surprisingly hard and does not have the flexibility of styrofoam.
Therefore, when the end face contacts the surface of the article to be packaged, there is a problem that the soft painted surface of the article to be packaged is damaged. Further, since the cardboard cushioning material is manufactured by cutting a required shape from a block in which a plurality of cardboard sheets are laminated and adhered with an adhesive or the like, unnecessary portions of the block are wasted. There was a problem of becoming.

In view of the above, the present invention has a leg on the lower surface.
An object of the present invention is to provide a corrugated cardboard packaging cushioning material which does not damage the surface of the article to be packaged which has a projection on the rear surface and which is easy to take off paper.

[0006]

The cushioning material for packaging according to the present invention is formed from a single blank sheet made of corrugated cardboard. And a folding line 1 is formed on the other side of the opposite long side.
6, a decorative bottom plate 19 is connected to the front plate 17 via a fold line 18, and the decorative bottom plate 1
A decorative backboard 22 is connected to one long side of the base 9 via a fold line 21, and engaging pieces 20 are respectively protruded from opposite short sides of the decorative bottom board 19, while the facing backplate 4 faces The outer plates 6 are continuously connected to the short sides of the bottom plate 2 via fold lines 5, and the inner plates 8 are connected to the outside of the outer plates 6 via fold lines 7, respectively. On both sides of the front plate 17, the decorative bottom plate 19 and the decorative back plate 22, a reinforcing bottom plate 14 overlapping with the bottom plate 2 via the folding line 10 is connected to the both outer plates 6. 8, a reinforcing bottom plate 15 overlapping with the reinforcing bottom plate 14 is provided continuously through the folding line 11. On one side, the reinforcing side plate 3 is connected to the reinforcing bottom plate 14 via a fold line 31.
3, and a reinforcing side plate 34 is provided on the reinforcing bottom plate 15 via a fold line 32, and one of the inner plates 8 is provided.
Write the engagement notch 9 to one engages the engagement piece 20 is formed, also notches 35 of one engaging the engaging piece 20 on the reinforcing plate 34 is formed on, furthermore, the reinforcing bottom plate 14, 15 and a packaging cushioning material in which the decorative bottom plate 19 is formed with a through-hole 36 for accommodating a leg of the article to be packaged,
Each of the inner plates 8 is bent inward at the fold line 7 and overlapped on the outer plate 6, and the reinforcing bottom plate 15 is overlapped on the reinforcing bottom plate 14, and the back plate 4 and each of the overlapped inner plates The plate 8 and the outer plate 6 are connected to the folding lines 3 and 1 respectively.
At 0 and 11, the inner plates 8 and the outer plates 6, which are raised at right angles and overlap each other, are placed 90 inward at the folding line 5.
The reinforcing side plates 33 and 34 are superposed on the bottom plate 2 in a state where the reinforcing bottom plates 14 and 15 are superposed.
Bending at the fold line 31 and 32, wherein the polymerized inside of one of the inner <br/> side plates 8, wherein the front plate 17 fold line 16
The decorative bottom plate 19 is bent at the fold line 18 to be superimposed on the reinforcing bottom plate 15 , and the decorative back plate 22 is reversely folded at the fold line 21 and overlaps with the back plate 4. characterized in that engaged respectively engaged with the engaging piece 20 the cut 9 and the reinforcing plate 34 to form the notch 35 formed in one of the inner side plate 8 above the provided on.
