Hold in. The substrate-storing inner box 1 buffered and held in this way is housed in the outer box 2.

[0005]

However, as illustrated in FIG. 8 and FIG.
In addition, the plate-shaped Styrofoam 14 is bonded to a position that matches the size of the substrate 3, and it is necessary to change the size of the corrugated board 15 and the bonding position of the plate-shaped Styrofoam 14 according to the size of the substrate 3.

Further, the number of man-hours required for bonding the corrugated cardboard 15 and the Styrofoam 14 when producing the packaging material and the number of man-hours required for sorting the corrugated cardboard and the Styrofoam when incinerating the packaging material are large, resulting in poor production efficiency and high cost. There was a problem of being lost. In addition, it took a storage space to store the packaging material, which was inefficient in terms of packaging material management.

It is an object of the present invention to provide a low-cost packaging material that solves the above-mentioned problems and that is efficient in production of small amounts of various products and is efficient in management.

[0008]

In order to achieve the above-mentioned object, the present invention is a packaging material only for corrugated board when packaging products of different sizes, and by changing the folds of corrugated board according to the product dimensions. It has a packaging structure that can be used to mount the product.

Further, the groove of the corrugated board is connected to the groove, and the claw is made to go under the inner upper surface of the packing material to prevent the upward deformation of the packing material and maintain the shape after the corrugated board is assembled. .

Therefore, according to the present invention, products of different sizes can be packaged in a packaging material made only of corrugated board, and since Styrofoam is not used. Eliminating the work of separating the corrugated board and the styrofoam when incinerating the packaging material and incinerating the packaging material, it is possible to package products of different dimensions with packaging material made only of corrugated cardboard, so it is efficient in terms of high-mix low-volume production and management. By storing the material in the unfolded state, a large amount of packaging material can be manufactured inexpensively without taking up any storage space.

Further, since no adhesive or tape is used when assembling the corrugated board, the labor for fixing the shape of the corrugated board can be saved, and efficient packaging work can be realized.
