Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing material which is used for storing an object to be packed in a packaging box and holds the object to be packed in the packaging box.

[0002]

2. Description of the Related Art As a packing material for holding an object to be packed in a packaging box, conventionally, as shown in FIG. 11, a thin plate-like support plate 91 such as cardboard or corrugated cardboard is provided. There is one in which a hole portion 93 into which the article to be packed 92 is inserted is formed. When the object to be packed 92 is housed in a packaging box (not shown) using the packing material 90 including the support plate 91, the outer surface of the object to be packed 92 is brought into contact with the edge of the hole 93 to wrap the object. The storage position of the article to be packed 92 in the box is defined.

Therefore, the hole portion 93 has a shape substantially corresponding to the sectional shape of the object 92 to be accommodated on the plane of the support plate 91. When the object 92 has a rectangular cross section, the hole portion 93 is It is formed in a rectangle. Further, when packing an article to be packed 92 such as an AC adapter in which a projection 94 such as a plug is projected from the main body, a notch 93 a for avoiding interference with the projection 94 is provided in the hole 93. It is formed.

In this case, the projecting surface 92a of the article to be packed 92 from which the projecting object 94 projects comes into contact with the edge of the hole 93 in a range excluding a portion facing the notch 93a.

[0005]

However, in the conventional packing material, the hole formed in the support plate allows only a single size of the packing object to be inserted, so that the packing object is stored. When the size of the product changes, it is necessary to use a support plate having holes of different shapes, and it is necessary to prepare the same number of packing materials as the size of the objects to be packed.

Further, in the conventional packing material, the storage position of the object to be packed on the plane of the support plate is defined only by the contact between the edge of the hole and the object to be packed. The storage position of the article to be packed in is to be defined only by the thickness of the support plate formed by a thin plate. For this reason, when an external force in the plane direction of the support plate acts during transportation of the packaging box containing the article to be packaged, the article to be packaged tends to move in the plane direction of the support plate, and this moving force causes the holes in the support plate to move. By acting on the edge of the product, the corners of the hole will be torn or broken, and it will not be possible to reliably specify the position of the items to be stored in the packaging box, causing damage to the items to be packaged. There was a problem.

In particular, when the notch is formed in the hole, the length of the notched edge portion becomes short and the edge portion is opened at one end, so that the notch in the support plate is formed. The strength of the portion (the portion indicated by the broken line in FIG. 11) that is continuous in the direction orthogonal to the cut edge portion decreases, and FIG.
A tear 95 shown in FIG. 12A and a break 96 shown in FIG.

An object of the present invention is to provide a contact member having a plurality of folding lines including the edge of the hole in the hole into which the article to be packed is inserted, so that the number of times of bending of the contact member can be selected. Can accommodate changes in the size of the items to be inserted into the holes, use a single support plate for multiple items of different sizes, and use a single edge for the holes. Or, it can be bent several times to increase the strength of the edge part that comes into contact with the object to be packed, and the support plate may be broken or broken when the object to be packed or the packaging box containing the object to be packed is transported. Another object of the present invention is to provide a packaging material capable of reliably restricting movement of an object to be packed in a packaging box with a simple configuration.

[0009]

According to a first aspect of the present invention, a thin plate-like support plate is formed with a hole portion into which an object to be packed is inserted, and a linear edge portion of the hole portion is formed into a first portion.

According to the first aspect of the present invention, an abutting member having a linear edge portion as a first folding line is formed to extend in a hole portion of the support plate into which the article to be packed is inserted. At least one second fold line parallel to the first fold line is formed on the contact member. Therefore, the opening area of the hole changes depending on whether the contact member is bent only at the position of the second fold line or at the position of the first fold line and the position of the second fold line. The storage position of a plurality of items to be packed is defined by a single support plate. Further, by bending the contact member at the second fold line position, or at the first fold line position and the second fold line position, the thickness or area of the portion that comes into contact with the article to be packed changes, and The strength of the portion that contacts the object increases. In addition, thin plates can be

According to a second aspect of the present invention, the length from the second fold line to the end of the contact member is parallel to the first fold line from the second fold line. Among them, it is characterized in that it is at least the length to the end closer to the first folding line.

In the invention described in claim 2, when the contact member is bent only at the second folding line position, the position of the end of the contact member is at least at the position of one end of the support plate. Match. Therefore, the end of the contact member bent only at the second folding line position is defined by the same configuration as the position of one end of the support plate, and the support of the contact member in the contact direction of the packaged object is achieved. The reinforcing condition of the plate is reliably maintained.
