[First Embodiment]
As discussed in the above-mentioned “Background Technology”, when a high-grade product is purchased in recent years, not only the purchased product but also the product box 2 in which the product is stored has a sense of quality and functions. It has a nature and is now regarded as part of the product.

Therefore, the merchandise box 2 cannot be used for transportation as it is, and in most cases, the merchandise box 2 containing the merchandise is further stored in the packing box 3 and used for transportation in a double-packed state.
As shown in FIG. 2, when storing the product box 2 in the packing box 3, of course, the product box 2 is moved in the packing box 3 so that the product box 2 is not destroyed or damaged on the surface of the product box 2. Between the product box 2 and the packing box 3, the cushioning material 1 (the cushioning material 1 according to the first embodiment) is provided.

Here, in order to clarify the explanation in the present invention, terms in the present specification are defined.
A box that contains a product, has a predetermined function or is decorated, and is considered to be a part of the product from the consumer's point of view. Corresponds to the “packaged object” in the range). The product box 2 is not limited to paper, and may be made of plastic or a wooden box. As a form of the product box 2, in the first embodiment, the product box 2 is square in plan view and has a predetermined height. For example, if the horizontal width, depth, and height are substantially the same dimensions, the product box 2 has a cubic shape. If the height is lower than the horizontal width and depth, the product box 2 has a flat box shape.

In order to transport the product box 2 to the consumer / user, a box for further storing the product box 2 is referred to as a “packing box 3 (exterior box)”. Various materials are conceivable as the packaging box 3, but in view of the recent transportation situation, corrugated cardboard is preferable.
The packaging box 3 is such that the product box 2 is completely housed inside. With respect to the packaging box 3, the lower lid (bottom part) is previously closed with an adhesive tape such as a gum tape. After inserting the product box 2, the upper lid is closed and sealed with an adhesive tape, and then an invoice is applied to the outer surface. Thus, it can be sent to a customer (user) using a courier service or the like.

Moreover, although mentioned later for details, the goods box 2 and the packing box 3 need to be a similar shape on the characteristic of the shock absorbing material 1 of this invention. In particular, the size of the packaging box 3 needs to observe the following points with respect to the product box 2.
That is, when the product box 2 is arranged in the center of the packing box 3, the upper gap dimension and the lower gap dimension are the same, and the upper gap dimension (in other words, the lower gap dimension) The gap dimension and the front and rear gap dimensions are all substantially the same value (A in FIG. 4).
