2. Description of the Related Art In recent years, instead of styrene foam packaging cushioning materials which cannot be recycled and have a bad influence on the living environment due to their disposal, for example, Japanese Unexamined Patent Publication No. Hei 4-2677
As described in Japanese Patent Publication No. 69, a packaging cushioning material or packaging spacer made of a corrugated cardboard sheet or other renewable sheets has been proposed. The packaging cushioning material of the above publication supports and protects the corners of the packaged article when the packaged article is packaged in an outer box, and each part thereof is constituted by a laminated body of cardboard. I have. As described above, when each part of the cushioning material for packaging is constituted by a laminated body of cardboard, the structure is simplified, but there is a problem that the bulk specific gravity (weight per unit volume) of the cushioning material for packaging increases and the cost increases. .

[0003] For this reason, for example, Japanese Patent Application Laid-Open No. Hei 8-58842 proposes a cushioning material for packaging using a square tubular hollow body made of cardboard. As shown in FIGS. 58 and 59, the packaging cushioning material described in the above publication has cuts parallel to both ends of a hollow main body 6 having a rectangular cross section so as to intersect one edge at right angles. 60 and 61 are formed, and a cut portion is formed in the ridge portion between the cuts 60 and 61 in a manner of forming a plurality of symmetrical uneven portions 62 and 63. By forming fold curves 64 and 65 so as to connect both ends of the cuts 60 and 61, flaps 66 and 67 are formed on both sides of the main body 6 sandwiching the ridge. And the concave and convex portions 62 and 63 are engaged with each other to form a concave portion 60a by the flaps 66 and 67.

The packing cushioning material packs the packaged object in an outer box with the end of the packaged product guided and supported in the recess 60a.
