CONSTITUTION:Three laminate plates 11-13 which are provided at one end side of a corrugated fiberboard are respectively bent at a folding line to form a three layer structure. At the same time, the corrugated fiberboard raw material is bent respectively at folding lines 36, 30 in such a manner that an intermediate plate 39, fastening plate 33 and engaging plate 29 which are provided at the other end side of the corrugated fiberboard raw material may be wrapped in, and a fastening part 34 at the leading end side of the fastening plate 33 is fastened to the upper edge of an incision 26 on a standing plate 22 to build up a cushioning body for packaging. |
