PROBLEM TO BE SOLVED: To make it difficult to tamper with a commodity, and easily find the tampering.SOLUTION: A packing box comprises: front and rear plates 1, 3; both side plates 2, 2; bottom plates 5, 6; and a lid plate 7. An upper edge of one side plate 2 has a sub lid plate 8 disposed continuously thereto, an insertion piece 10 on a tip end edge of the lid plate is inserted into an insertion port 12, hook pieces 11 on both sides of the insertion piece 10 are hooked to both side edges of the insertion port. Length Lof the insertion port is set to become shorter than length Lobtained by adding widths of the hook pieces 11 and insertion piece 10. The insertion port has width t reaching a rear side of an upper edge of the side plate, and a finger hook hole 13 is formed on the lid plate on a rear part of the insertion port, and a perforation 14 extending from the finger hook hole to the hook pieces is formed. When a commodity is stored and once the box is sealed, the box cannot be opened unless the perforation 14 is cut and the insertion piece is split up. Therefore, even when someone is going to open the box and tamper with the commodity, a sign of opening the box remains, and finding of irregularities is facilitated, so that, tampering can be prevented in advance. |
