Abstract

An aspect of the invention is directed to a packing box in which at least part of an opening through which to insert and take out an object to be packed is closed by inside lids that are opposed to each other in a plane, wherein: the inside lids have a cut portion including a cut that is shaped so as to be suitable for the external shape of a portion of the object and folded portions formed by folding the respective inside lids, and, when the inside lids are closed, the cut is fitted with the portion of the object housed in the packing box to fix the object in a state that walls, opposed to each other, of the respective folded portions are in contact with each other.

First claim

What is claimed is:

1. A packing box comprising inside lids, at least part of an opening of the packing box through which to insert and take out an object to be packed being capable of being closed by the inside lids, the inside lids opposed to each other in a plane, wherein:
the inside lids have a cut portion including a cut that is shaped so as to be suitable for the external shape of a portion of the object and folded portions formed by folding the respective inside lids, and, when the inside lids are closed, the cut is fitted with the portion of the object housed in the packing box to fix the object in a state that walls, opposed to each other, of the respective folded portions are in contact with each other,
the cut portion is formed in one of the folded portions so as to be suitable for the position of the portion of the object, and the cut is formed in a wall excluding the wall that comes into contact with the wall of the other folded portion when the inside lids are closed.

2. The packing box according to claim 1 , wherein:
each of the folded portions is formed by folding the corresponding inside lid plural times; and
when the inside lids are closed, a part of the each of the folded portions, which is formed by folding the corresponding inside lid plural times, is in contact with a surface, opposed to the opening, of the object housed in the packing box to fix the object.

3. The packing box according to claim 1 , wherein:
the inside lids are a first inside lid that is formed with the cut and a second inside lid that is not formed with the cut; and
the first inside lid has a mark that indicates the position of the portion of the object housed in the packing box in closing the first inside lid in a state that the second lid is open.

4. The packing box according to claim 1 , wherein:
the cut portion is formed in one of the folded portions; and
the inside lids have a mark that indicates the position of the portion of the object housed in the packing box in closing one of the inside lids in a state that the other inside lid is open.

5. The packing box according to claim 1 , further comprising an outside lid that covers the inside lids, wherein:
each of the folded portions is formed by folding, plural times, to the same side, the corresponding inside lid whose length in a direction in which to extend toward a free edge thereof is within the length of the outside lid in a direction in which to extend toward a free edge thereof.

6. The packing box according to claim 5 , wherein the outside lid is bounded by a shorter side of the opening.

7. The packing box according to claim 5 , wherein the outside lid is bounded by a longer side of the opening.

8. The packing box according to claim 1 , wherein the folded portions are arranged in a direction orthogonal to a direction in which flutes of corrugated cardboard extend, and the folded portions come into contact with inner surfaces, adjoining the opening, of the packing box when the inside lids are closed.

9. The packing box according to claim 1 , wherein the cut portion fixes the object so as to prevent rotation of the object in a state that the inside lids are closed.

10. A packing box comprising inside lids, an opening of the packing box through which to insert and take out an object to be packed being capable of being closed by the inside lids, the inside lids opposed to each other in a plane, the packing box further comprising:
an outside lid that covers the inside lids; and
a post that is disposed approximately perpendicularly to the inside lids between the outside lid and the inside lids and supports the outside lid, wherein the post is made of a material having a corrugate cardboard structure in such a manner that flutes of the material extend in a direction of height with respect to top surfaces of the inside lids.

11. The packing box according to claim 10 , wherein the post is formed by separating a portion of a separation portion that is part of one of the inside lids and is defined by plural cuts and a folding line from the one inside lid, and folding the separation portion along the cuts and the folding line.

12. The packing box according to claim 11 , wherein the post is formed by folding the separation portion along the cuts and the folding line so as to be able to surround a portion of the object, and is disposed at such a position as to be fitted with the portion of the object.

13. The packing box according to claim 11 , wherein the separation portion is part of one of the inside lids whose length in a direction in which to extend toward a free edge thereof is within the length of the outside lid in a direction in which to extend toward a free edge thereof.

14. The packing box according to claim 10 , wherein the post is formed by cutting off a portion of a separation portion that is part of one of the inside lids and is defined by plural cuts and a cutting line from the one inside lid along the cutting line, and folding the separation portion along the cuts.

15. The packing box according to claim 10 , wherein the inside lids being closed are in contact with a portion of the object.

16. The packing box according to claim 15 , wherein one of the inside lids has a cut that is shaped so as to be suitable for the external shape of a portion of the object, and, when the inside lids are closed, the cut is fitted with the portion of the object housed in the packing box to fix the object.
