To allow a decorative plate to appear as floating from a movable base in a standing state to obtain excellent representation effects by making a constitution that the decorative plate is pulled by a coupling piece to stand up when the movable base is opened to stand and by providing the decorative plate at an arbitrary distance from the movable base.

While an article 8 is being packaged, a lid 3 is put over an upper face of a box body 2. A movable base 30 is stuck to a rear face of the lid 3 which is attached to the upper face of the box body 2 via a hinge 40, and a decorative plate 6 is connected to a decorative base plate 5 fixed to an upper face along the hinge 4 of the box body 2 by a hinge structure due to a fold line, so that the decorative plate 6 is fallen down on the upper face of the box body 2 in a state overlying on an internal face of the lid 3 while the lid is closed. If the lid 3 is opened in this state, the movable base 30 is pulled by a coupling piece 7, so that the decorative plate 6 is made to stand while being kept in parallel to the lid 3. Since the decorative plate 6 is at a certain distance from the movable base 30, it appears three-dimensional.
