PURPOSE:To prevent light leakage without affecting taking out of a film from a package case by providing light shielding walls near holes for case unsealing pins in a groove existing at the outside edge of an aperture side member. CONSTITUTION:The light shielding walls are provided near the holes for case unsealing pins in the groove 54 existing at the outside edge of the aperture side member constituting a case for disk films. Directors 56 are the adhesion points to a label side member. The light shielding walls at the outside edge have partly projecting parts 57 on the outside. Namely, the projecting parts 57 near the elliptical holes on both the right and left sides of the aperture side member are further extended to contact the directors 56 and to create the light shielding walls which can prevent entry of light. Exertion of an undersirable influence on taking the film out of the package case is thereby eliminated and the light leakage is prevented by the simple method. |
