REINFORCED LAMINATED BODY, ENCLOSED CASE AND PACKING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reinforced laminated body that improves productivity by a simple configuration and has a high strength at a low cost, and to provide an enclosed case and a packing device. SOLUTION: Cutouts 38 and 39 are formed in a blank 20 made of a corrugated board. The blank 20 is inverted by folding cutout portions 40 and 41. Engagement-flap extension panels 36 and 37 are folded so as to be laid over the cutout portions 40 and 41. Thereby engagement flaps 11a and 11b with the reinforced laminated body 80 having a triple structure is formed. COPYRIGHT: (C)2007,JPO&INPIT
