JPH111262A - Corner cushioning body made of corrugated paper - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a corner cushioning body made of corrugated paper with effective cushioning characteristics which requires a fewer assembly processes by making the same foldable in one direction as much as possible in assembling from an unfolded condition punched out from a corrugated panel paper and which yields less waste in cutting. SOLUTION: One side end of a roughly square base 1 is jointly provided with an outside panel 6 and a cubic body forming panel 8 for corner cushioning which, after being folded in a rolled shape, touches both corner faces of an article to be packaged. This roughly square cubic body forming panel 8 for corner cushioning is so structured that a support panel 10 which is formed with a cutting line 9 and which becomes a touching face of the corner of the article to be packaged by being folded along a diagonal line in one side, a stand up support panels 11, 12, and an aggregated panel 13 which is laid on the base 1 in an inserted condition are connected through a folding line. The folding lines 16, 17 of the stand up support panels 11, 12 of the aggregated panel 13 and the folding linens 14, 15 of the support panel 10 are folded inward to raise the stand up panels 11, 12, and each folding line of the outside panel 6 is folded inside in a rolled condition to raise the outside panel 6 and to lay the aggregated panel 13 on the base 1.
