TECHNICAL FIELD OF THE INVENTION
The present invention relates to a package, and more particularly, to a package that protects a package from an impact applied to the box by holding the package away from the wall of the box.
[0002]
[Prior art]
Conventionally, boxes for transporting and storing other vulnerable articles such as pottery, glassware, electric / electronic equipment, precision mechanical parts, etc. are conventionally made of boxes made of foamed polystyrene or cardboard boxes with corner pads. Or foamed plastics, which are packed with loose cushioning materials or those packed in small bags, have a problem in disposal after use.
[0003]
For this reason, efforts are being made to reduce the amount of packaging material used and to facilitate disposal and incineration.
As one of the manifestations, so-called “hammock packaging” has been proposed and partially put into practical use.
The “hammock packaging” is, for example, as shown in FIGS. 8 and 9, the supports 50 and 52 in which the elastic sheet 30 is stretched over a plate-like frame, and the whole of the box 60 is sandwiched between the objects to be packaged 40 from above and below. This is a package that is placed inside and holds the packaged object 40 in the space inside the box 60 in a state separated from the wall of the box 60 (see Patent Documents 1 to 4).
Note that, as a material for forming the box 60, corrugated paper or cardboard is often used.

In this hammock packaging, the object to be packaged is a sheet of elastic material, so the packaging target is limited to relatively small articles and light-weight items. Problems such as damage to the bottom wall of the outer box due to bottoming out occur.
As a countermeasure, it is conceivable to first increase the strength of the elastic sheet. However, when storing the article to be packaged in a box, the elasticity of the elastic sheet increases the repulsive force, making it difficult to store the article to be packaged. There is a problem that one of the pair of upper and lower frames, particularly the lower frame, is crushed.
