Abstract of the Disclosure A light-tight, self-contained canister for preventing a roll of core wound photosensitive media, used in a microfiche or microfilm reader-printer, from being damaged or exposed to actinic light during shipping, storing and dispensing. The canister includes an open ended opaque tubular sleeve closed at both ends by opaque end caps lockingly interconnected by a rigid tie bar extending longitudinally between the end caps along the core of the photosensitive media. At least one end of the tie bar includes a pair of resilient fingers. The fingers deform upon pressure engagement with a central receiving aperture formed in the end cap. Each end cap also includes a hub portion sized to rotatively support the roll of core wound media within the canister. Also, in an alternative embodiment, the fingers may be associated with the aperture and deformable upon engagement with the tie bar. In still another alternative embodiment, the interconnecting function of the tie bar may be incorporated into each end cap so that only one mold is required for its manufacture.
