The slit 23c has a linear shape with the left-right direction as the longitudinal direction. The width (vertical width) of the slit 23c is not particularly limited, but can be twice or more and four times or less the thickness of the corrugated cardboard sheet. In the support member 10, a pair of tongue pieces 51 are defined on the outer surface plate 22, and the support piece 21 is maintained on the inner surface plate 23 in parallel with the bottom wall 130 of the box body 100. By providing a pair of slits 23c into which the support pieces 21 are inserted, it is easy to maintain the sheet surfaces of the plurality of support pieces 21 perpendicular to the corners of the contents P. As a result, the content P can be held more easily and stably.

The support piece 21 partially supports the corner portion (corner portion in a plan view) of the content P from the side. The support piece 21 is a two-layer body in which a corrugated cardboard sheet is folded in half at the hypotenuse 21a. Therefore, the thickness of the support piece 21 is substantially equal to twice the thickness of the corrugated cardboard sheet. The support piece 21 is inserted into the slit 23c of the inner surface plate 23 and protrudes beyond the inner surface plate 23. Therefore, the protruding length L (see FIG. 2) of the support piece 21 is larger than the distance D1 between the outer surface plate 22 and the inner surface plate 23.

The support piece 21 supports the content P from the horizontal direction on the hypotenuse 21a. The side surface of the content P may be in contact with the inner surface plate 23 or may be separated from the inner surface plate 23 while being supported by the support piece 21.

The height position of the support piece 21 in the box body 100 is not particularly limited. However, it is desired that the support piece 21 can support the position of the center of gravity of the content P from the side. Therefore, when the vertical distance between the pedestal plate 27 and the upper surface of the connection plate 24 is D2, D2 / 2 is preferable as the upper limit of the vertical distance between the pedestal portion 27 and the support piece 21, and D2 / 3 Is more preferable.

<Advantage>
The support member 10 is provided so that a right-angled isosceles triangle-shaped support piece 21 supports a corner portion of the content P by its hypotenuse 21a. Since the support piece 21 is formed by folding the corrugated cardboard sheet at the hypotenuse 21a so that the ridgeline R of the core of the corrugated cardboard sheet is orthogonal to the support member 10, the support member 10 has high strength in the sheet surface direction and is a sheet. Strength anisotropy is unlikely to occur in the plane direction. Therefore, the support member 10 can easily and stably hold the content P housed in the box body 100.

Since the support member 10 has four support pieces 21 arranged corresponding to the four corners of the box body 100, even if the box body 100 is tilted during transportation or the like, the four support pieces 21 are used. The content P can be supported at four points. For example, when the content P is a package made of a cardboard box, the corners of the content P are easily damaged due to an external impact or the like. In this respect, the support member 10 partially supports the corner portion of the content P from the side by the support piece 21 to alleviate the impact applied to the content P and easily and appropriately support the content P. Can be protected. In other words, the support member 10 can easily and stably hold the content P in the box body 100 by selectively supporting the fragile portion of the content P by a plurality of support pieces 21. ..
