  • Patent number: 5941387
    Abstract: A lightproof package of photographic strip material, which is wound around a core and forms a hollow-cylinder film roll, its outer circumferential surface enclosed by a cover sheet, its inner circumferential surface enclosed by the core, and its end faces enclosed by thin-walled end caps, so that the packaging does not essentially change the outer dimensions of the existing film roll. The photographic material is not inadvertently exposed when the film roll is partially unwound for use and placed into an operating device under daylight conditions.
