Protective card and packaging box using the same

摘要

Problem to be solved: to provide a simple structure protective card and a packaging box using the same.A first flexible plate 84 (1) is provided on one end portion of the connecting plate 82 through a first bent line 86 (1).A second flexible plate 84 (2) extending through the second folding line 86 (2) parallel to the first folded line 86 (1) is provided on the opposite side end portion of the connecting plate 82.The spacing between the first and second junction lines 86 (1) and 86 (2) is shorter than the thickness of the rectangular parallelepiped container.The inner surface of the connecting plate 82 is opposed to one end surface in the longitudinal direction of the rectangular parallelepiped housing, and the outer surface abuts against the inner surface of the lid.The first and second flexible plates 84 (1) and 84 (2) are opposed to the surface and the rear surface of the rectangular parallelepiped housing, and the tip portion slides in sliding contact with the inner surface of the rectangular cylindrical body, and the corner portion of the one side surface of the rectangular parallelepiped housing abuts against the inner surface to deflect outward.Diagram
