PROBLEM TO BE SOLVED: To secure a sealing state, make it difficult to tamper, 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; a lid plate 7; an insertion piece 10; and a flap piece 11, and the insertion piece is inserted into inside of the front plate for sealing the packing box. The insertion piece is disposed continuously to the lid plate via an arc-state fold line r1, and when the insertion piece is inserted, both side edges of the insertion piece are energized inward, along an outside salient shape by the fold line. By the energization force, an undercut 12 of a root of the insertion piece enters a notch 13 of the flap piece, an edge 10a of the root of the insertion piece is engaged with an edge 11a of the flap piece, and thereby sealing is secured. When the insertion piece is pulled up for opening the box, an opening display piece 15 is also pulled up. Therefore, opening of the box can be surely found, and even when someone is going to improperly open the box and tamper with the commodity on the commodity distribution process, finding of the irregularities is facilitated, and tampering is prevented in advance. |
