Similarly, a gap G ₂ exists between the insertion piece 31 and the insertion piece 31 as shown in FIG. A vertical gap G ₃ exists between the bottom plate 10 and the tip of the upright cushioning piece 57 protruding below the upright receiving plate 53. Therefore, the initial impact at the time of dropping is softened by deforming so as to eliminate these gaps G ₂ and G ₃ , respectively, and a further improvement in cushioning property is obtained.

Therefore, it is possible to control the impact load applied to the article to be packaged 70 by changing the ratio of the sizes of the tip portions and the root portions of the cushioning pieces 55, 57, 58 and the shape thereof. Alternatively, these buffer pieces 55, 5
7,58 of the front end portion and the top plate 28, side plates 12 or by adjusting the size of the gap G _1, G _2, G ₃ between the bottom plate 10, to control the impact load applied to the packaged articles 70, Will be possible.

The impact in the vertical direction is received by the vertical holding plate 46 which supports the horizontal receiving plate 54 via the bending line of the upper edge of the horizontally elongated opening 61. Therefore, as shown in FIG. 20, in order for the vertical holding plate 46 to absorb a shock, semicircular openings 62 are formed at both sides of the laterally long opening 61 at the root thereof as shown in FIG. . Such a semicircular opening 62 softens the initial impact at the time of dropping and improves the cushioning property. Moreover, the impact load can be arbitrarily adjusted by adjusting the size of the opening 62 and the gap between the opening 62 and the horizontally long opening 61.

As described above, according to the packaging box of the present embodiment, the corrugated paperboard shown in FIG. 1 is used to assemble the packaging box immediately before packaging without any additional cushion such as a cushion made of expanded polystyrene resin. Can be used. The cushioning effect on the article to be packaged 70 utilizes the bent shape of the corrugated paperboard 9 to enable cushioning against a drop impact.

In particular, as for the cushioning pieces 55, 57 and 58, which are portions to be provided with a cushioning effect by the corrugated paperboard 9, all of them have a substantially trapezoidal shape by changing the dimensions of the tip and the root portion, and the stepping cushioning performance is obtained. Trying to get.
Further, the vertical holding plate 46 is formed with a semicircular opening 62 at the base side thereof so as to further improve the cushioning performance.
