Abstract

Not all, but one lateral surface part (41) of a plurality of lateral surface parts (41) of a box main body (4) is configured so as to have an outer lateral surface part (41a) and an inner lateral surface part (41b) which overlap each other. A part of a refrigerator is covered by this double structure of the outer lateral surface part (41a) and the inner lateral surface part (41b). For this reason, even if an excessive external force is applied to the covered part of the refrigerator, the external force is absorbed by the double structure of the outer lateral surface part (41a) and the inner lateral surface part (41b), and the covered part of the refrigerator is not dented by the external force.

Description

Packing material

This invention relates to a packing material for packing an object to be packed such as a refrigerator or a shelf.

Conventionally, as a packing material, there is a packing material including a box body that covers the periphery of an object to be packed, and a protective sheet disposed between the box body and the object to be packed (Japanese Patent Laid-Open No. 8-258887). Patent Document 1). When an excessive force is applied to the object to be packed from the outside, the external force is absorbed by the protective sheet to prevent the occurrence of dents due to the external force on the object to be packed. That is, the box body has a single structure (single cardboard), and the strength of the box body is small, so that the protective sheet is subjected to external force.

However, the conventional packing material has a problem that it is difficult to pack the packing material into the packaged object because the protective sheet is disposed between the box body and the packaged object. Here, if the strength of the box body is improved by uniformly increasing the thickness of the box body without using the protective sheet, the thickness of the portion that does not require the strength of the box body is also increased. Thus, there is a problem that the cost of the box body is increased.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

(First embodiment)
FIG. 1 is a perspective view showing a usage state of the packaging material of the present invention. This packing material has a box body 4 (such as an exterior box), and this box body 4 covers the periphery of the refrigerator 2 as an object to be packed. The standard packing method of the refrigerator 2 will be described. The refrigerator 2 which is a heavy load is placed on the bottom base assembly 1 including the lower cushioning material, and the box body 4 is covered after the plastic bag 3. Thereafter, the upper cushioning material 5 is installed and sealed with the tape 6 as indicated by the phantom line. Finally, the base assembly 1 and the box body 4 are bound by the PP band 7. In addition, the arrow F direction in FIG. 1 shows the front side (door side) of the refrigerator 2.
