Two rows of cushioning materials 31 are attached in the width direction to the back side of the outer lid 12. The outer lid 1 is closed with the outer lid 12 closed.
The cushioning material 31 is also interposed between the inner cover 2 and the inner lid 22 of the interior box 20. Normally, foamed polyethylene is used as these cushioning materials 30, 31.

FIG. 6 is a perspective view showing the inside of the interior box, and FIG. 7 is a front view showing the inside of the interior box. As shown in these figures, the bottom surface and both side surfaces of the interior box 20 are configured by bending a double plastic cardboard 25 into a U-shape and fixing both ends with a frame 23, On the upper side of the bottom surface, a bottom mount 45 on which two support cushioning materials 40 for supporting the substrate G such as a glass plate are mounted and fixed, and on the inside of each side surface, a side surface for holding the substrate G is provided. Side mounts 55 to which the cushioning members 50 are attached are installed and fixed, respectively. These bottom mount 45 and side mount 55
Also use plastic cardboard. Support cushion 40
Has a structure in which two cushion plates 42 made of foamed polyethylene (antistatic type) are attached to both front and back surfaces of a plastic cardboard 41 with a gap therebetween.
The width of the gap is set to about twice the thickness of the cushion plate 42, and can be folded as shown in FIG.
In the illustrated example, the cushion plate 42 on the back side and the outer side of the support cushioning member 40 is fixed to the bottom mount 45, so that the support cushion 40 can be folded in the direction indicated by the arrow in FIG. On the other hand, the side cushioning member 50 is formed of a foamed polyethylene cushion plate in which a plurality of vertical grooves 51 are formed at equal intervals, and is attached to the side mount 55 with the grooves 51 facing up.

In the example shown in FIGS. 6 and 7, an upper pressing member 60 is provided between the substrate G and the inner lid 22 to press the upper side of the substrate G housed in the interior box 20. The upper holding member 60 includes a holding board 61 made of plastic corrugated cardboard, two cushion plates 62 made of polyethylene foam attached side by side on the lower surface thereof, and two holding cushioning members 63 attached side by side on the upper surface. Consists of The holding cushioning material 63 is composed of two cushion plates 63 made of foamed polyethylene on the back surface of the plastic cardboard 63a.
