<p>PURPOSE:To insure safety of contents and obtain a prevention structure against illegal unpacking, by providing a structure in which a sealed adhesive faces can never be accessed from the outside after assembling a box and closing a cover plate and a bottom plate. CONSTITUTION:Adhesive-applied faces 52,62, formed on the rear face of folded flaps 51,61 continuously fitted at the front end of a cover plate 5 and a bottom plate 6 can be bonded, contacting both upper and lower faces of a front wall B4 constituting an inner frame or the uppermost face of the front wall B4 and the bottom face of a rear wall, regarding to a completely assemblied box. Therefore, the adhesive face is arranged at the position inaccessible from the outside and hence even if a sharp blades like a knife is inserted into a completely packed box with an unpacking purpose, the inserted blades only shift between the rear wall face 3 and the face of the folded flaps 51,61 preventing illegal unpacking. In this way, illegal unpacking, which conventional packing boxes are exposed to at folded flaps, can be completely removed.</p> |
