PROBLEM TO BE SOLVED: To provide a packaging box that has a high tamper-proof effect, can surely leave a trace of opening and surely prevent tampering.SOLUTION: A packaging box is formed of a box body forming piece, and the box body forming piece is provided with: side surfaces 20 which are continuously connected in parallel to each other to be assembled into a cylindrical body; a cover piece 36 bent along a folding score 38 to close an opening part of the cylindrical body; a catching piece 58 continuously connected to the side edge part of the cover piece 36 via a folding line 64; a lock piece 66 integrally formed at the tip end part of the catching piece 58; and an insertion receiving part 68 formed at the side surface located in the vicinity of the catching piece 58. When the cover piece 36 is closed while the box body forming piece is assembled, the catching piece 58 is folded along the folding line 64 to be parallel to the side surface where the insertion receiving part 68 is formed. When the cover piece 36 is closed, the catching piece 58 is inserted into the insertion receiving part 68 together with the lock piece 66 and the lock piece 66 is locked on the insertion receiving part 68.SELECTED DRAWING: Figure 1 |
