PROBLEM TO BE SOLVED: To improve protection of goods. SOLUTION: Two side sheets 2, 3, a front sheet 4, a rear sheet 5, a top sheet 6 and a bottom sheet 7 are cut in a developing shape. A bonding margin 3b formed at one edge of the side sheet 3 and one edge the front sheet 4 are bonded to form a tubular shell 8. At the bottom sheet 7, an extension part 14 having a front sheet cover 11, a cover part 2 and a locking part 13 is formed toward its top end. At the top sheet 6, a cover part 6b, the first locking part 6c and the turned-up second locking part 6d are formed. By folding the extension part 14 in the front sheet direction, the locking part 13 is put between the first locking part 6c and the second locking part 6d, thus it is possible to constitute a sealing part of triple structure serving as the only opening of a goods case 1. |
