<p>PROBLEM TO BE SOLVED: To provide a packaging box which has a simple structure, generates a click sound continuously when a tray placed in a sleeve slides, and can position the tray in a state of being pulled out from the sleeve in an arbitrary length.SOLUTION: A packaging box comprises a tray 12 which stores an accommodation article and a sleeve 14 which accommodates the tray 12 slidably. In the tray 12, an engaging projection 33 projects outward. In the sleeve 14, a plurality of step parts 115 are provided continuously in a route of the engaging projection 33 when the tray 12 slides, and the engaging projection 33 of the tray 14 is elastically deformed and comes into contact with the step parts 115. In the tray 12, a bottom face 18 for placing a product and a side face 28 standing while being folded at an almost right angle with respect to the bottom face 18 are formed by being partitioned by a folding ruled line 54. The tray 12 has a U-shaped cut line 31 in the middle of the folding ruled line 54. An opening portion of the cut line 31 is positioned on the side face 28, a closing portion of the opposite side is positioned on the bottom face 18, and thereby the cut line 31 forms the engaging projection 33.</p> |
