Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a packaging box with a lock mechanism for cosmetics, etc., which eliminates a gap generated between the main body and the cover part of the box without spoiling the quality of the lock mechanism when the box is assembled. SOLUTION: By changing the shape of a ruled line existing between the cover part of a packaging box and a flap piece connected the cover part from a usual straight line shape to a shape protruding toward the tip end of the flap piece, a lock mechanism works. And in assembling the packaging box, by the bite of the flap piece and a flap, a stress is generated so that the cover part makes inroads into the main body. This results in the elimination of a gap between the main body and the cover part. |
