Abstract

A packaging material includes a first surface part that is adjacent to one side of a boundary line and has a bottom plate on which an object to be packaged is placed, and a second surface part that is adjacent to the other side of the boundary line and has a top plate that holds and wraps the object to be packaged with the bottom plate in a state of being folded along the boundary line, the boundary line being interposed between the first surface part and the second surface part, in which the bottom plate and the top plate are rectangular regions where one corner of the bottom plate and one corner of the top plate are in contact with each other at the boundary line, and portions of the first surface part and the second surface part, which are located outside four sides of a rectangular shape of the bottom plate and the top plate, are folding portions that are foldable at the four sides.

First claim

What is claimed is:

1 . A packaging material comprising:
a first surface part that is adjacent to one side of a boundary line and has a bottom plate on which an object to be packaged is placed; and a second surface part that is adjacent to the other side of the boundary line and has a top plate that holds and wraps the object to be packaged with the bottom plate in a state of being folded along the boundary line, the boundary line being interposed between the first surface part and the second surface part, wherein the bottom plate and the top plate are rectangular regions where one corner of the bottom plate and one corner of the top plate are in direct contact with each other at the boundary line, and portions of the first surface part and the second surface part, which are located outside four respective sides of each of a rectangular shape of the bottom plate and the top plate, are folding portions that are foldable at the four respective sides of each of the bottom plate and the top plate.

2 . The packaging material according to claim 1 ,
wherein, among four corners of the bottom plate, two corners other than the one corner are in contact with two sides of the first surface part orthogonal to the boundary line, respectively, and among four corners of the top plate, two corners, which are diagonal to each other, other than the one corner are in contact with two sides of the second surface part orthogonal to the boundary line, respectively.

3 . The packaging material according to claim 2 ,
wherein one remaining corner among the four corners of the bottom plate is in contact with one side of the first surface part parallel to the boundary line, and one remaining corner among the four corners of the top plate is in contact with one side of the second surface part parallel to the boundary line.

4 . The packaging material according to claim 3 ,
wherein the first surface part is provided with a bonding portion that is continuous in contact with one side of the first surface part parallel to the boundary line and that is bonded to a part of the second surface part.

5 . A packing material comprising:
the packaging material according to claim 4 ; and a box in which the packaging material is accommodated.

6 . A packing material comprising:
the packaging material according to claim 3 ; and a box in which the packaging material is accommodated.

7 . A packing material comprising:
the packaging material according to claim 2 ; and a box in which the packaging material is accommodated.

8 . The packaging material according to claim 1 ,
wherein the first surface part and the second surface part are each provided with two preliminary folding lines parallel to the boundary line at positions located inward by the same distance from the one corner and one corner diagonal to the one corner among four corners of each of the bottom plate and the top plate.

9 . A packing material comprising:
the packaging material according to claim 5 ; and a box in which the packaging material is accommodated.

10 . The packaging material according to claim 1 ,
wherein the folding portions are configured as triangular or trapezoidal portions whose bottom sides are the four sides of the rectangular shape of the bottom plate and the top plate.

11 . The packaging material according to claim 10 ,
wherein the folding portions have intermediate folding lines parallel to the four sides of the rectangular shape of the bottom plate and the top plate, respectively.

12 . The packaging material according to claim 11 ,
wherein the bottom plate is provided with insertion holes into which tip parts of the folding portions are respectively inserted in a case where the folding portions are folded along the intermediate folding lines.

13 . A packing material comprising:
the packaging material according to claim 8 ; and a box in which the packaging material is accommodated.

14 . The packaging material according to claim 11 ,
wherein the bottom plate and the top plate are provided with insertion holes into which tip parts of the folding portions are respectively inserted in a case where the folding portions are folded along the intermediate folding lines.

15 . A packing material comprising:
the packaging material according to claim 9 ; and a box in which the packaging material is accommodated.

16 . A packing material comprising:
the packaging material according to claim 7 ; and a box in which the packaging material is accommodated.

17 . A packing material comprising:
the packaging material according to claim 6 ; and a box in which the packaging material is accommodated.

18 . The packaging material according to claim 1 ,
wherein the top plate is provided with a buffering portion having a buffering function.

19 . A packing material comprising:
the packaging material according to claim 1 ; and a box in which the packaging material is accommodated.

20 . The packing material according to claim 19 ,
wherein the packaging material is accommodated in the box in a state where the folding portions are folded.
