<p>PURPOSE:To make it impossible for attached parts to be separated by an edged tool from outside in order to contrive an accurate prevention of tampering by a method wherein an inserting piece is secured to the inside of an outer reinforcing board joined to the inner surface of a right side board and the connecting piece of each connecting board is secured to the inside of two inserting boards joined to upper and lower side boards. CONSTITUTION:A paper case body is formed by folding all forming boards and pieces according to the folding lines a-s and then fastening them together at predetermined locations. At this time, doubly folded connecting boards 16, 17, 16' and 17' are secured to the inside of joined inserting boards 18 and 18' and to the inside of joined upper and lower side boards 19 and 20 and an inserting piece 2 inserted from an inserting hole 11 is secured to the inner surface of an outer reinforcing board 10 joined to a right side board 7. When the paper case 1 is used, it is packed with an article upon formation and then closed with a lid 4. The consumer tears off a zipper 3 to take out an article inside for use. In such a structure, since the attached parts can not be separated by inserting a thin edged tool from outside, the tampering with packed contents can be accurately prevented.</p> |
