方向が限定されることがあるなどという問題があった。The corner block Aa as described above becomes unnecessary after the product is taken out from the packaging container such as the corrugated cardboard box. In addition, incineration of the plastic corner block Aa causes pollution problems, and it must be sorted and stored for disposal, and it is bulky during storage, which makes the treatment difficult. .. Further, in the conventional plastic corner block Aa and corrugated cardboard, the strength of the bottom portion a, the horizontal wall portion b, and the vertical wall portion c is not sufficient, and it is difficult to perform a sufficient cushioning or protecting function. In particular, in the case of a corrugated cardboard corner block, there is a problem in that the yield when manufactured from a single piece of corrugated paper is poor and the direction of use may be limited.
