Then, the lid piece 68 is normally folded at 90 ° with the crease line 70, the insertion piece 72 is normally folded with the crease line 74, and the insertion piece 72 is inserted into the back side of the side surface 14 and locked, thereby forming the upper surface. Is done.

  Thereafter, the pulling portion 34 of the side surface 14 is reversely folded at an appropriate angle along the crease line 40, and the locking piece 32 and the pulling portion 34 are caused from the side surface 14. Next, the locking piece 32 is normally folded at approximately 90 ° with respect to the pulling portion 34 by the crease line 44 and the angle at which the pulling portion 34 is bent by the crease line 40 is returned to the original position, while the locking piece 32 is moved to the lid piece. Insert it into the 68 insertion port 76. At this time, the end surface 32a formed by the cutting line 42 of the locking piece 32 is locked and locked to the stepped portion 72a formed by the convex shape of the insertion port 76 of the insertion piece 72, FIG. The state shown in FIG.

  When opening, as shown in FIG. 4, the raised portion 48 of the take-out portion 46 is picked and raised, the sewing machine wire 50 is broken, and the take-out portion 46 is removed. Then, the lid piece 68 is lifted up and opened. The locking piece 32 is released from the side surface 14 in a state of being integrated with the take-out portion 46 and unlocked, and opens together with the lid piece 68. In addition, even if the locking piece 32 is pulled out and forcibly opened without breaking the sewing machine wire 50, the locking piece 32 comes into contact with the stepped portion 72 a of the insertion port 76, and the insertion port 76 or the cutting line 42. It cannot be opened unless it is deformed or part of the surrounding area is damaged. Therefore, the opening trace remains reliably by opening anyway, and it has a reliable tampering prevention effect.

  According to the packaging box 10 with a tamper-proof function of this embodiment, it is possible to provide a tamper-proof function simply by assembling the box-forming pieces with a simple structure, and reliably protect the product from tampering. Furthermore, another member such as an adhesive tape is unnecessary, and it is easily assembled and inexpensive. When opening, it is possible to easily break the sewing machine wire 50 and remove the external portion 46 from the side surface 14 by simply picking and raising the convex portion 48 to unlock the locking piece 32. The end face 32a of the locking piece 32 abuts on the stepped portion 72a of the insertion piece 72, and it is difficult to pull out the locking piece 32 from the insertion port 76. The sewing machine wire 50 must be cut to remove the external portion 46. Since it cannot be opened and the opened mark is reliably left, the tamper-preventing effect is high.
