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.

A light-tight, self-contained canister for preventing a roll of core wound photosensitive media, containable therein, from being damaged or exposed to actinic light during shipping, storing and dispensing, comprising: a canister sleeve for surrounding the roll of core wound photosensitve media, said sleeve having two open ends and a media exit slot running along one side of said sleeve parallel to the central axis of said roll of core wound photosensitive media; two opposed end caps for closing both ends of said sleeve, and at least one of said end caps having a central receiving aperture and both end caps having a peripheral edge cooperating with said open ends of said sleeve to form a light tight seal; a rigid tie bar extending longitudinally between said end caps along the central axis of said roll of core wound photosensitive media and said sleeve; and means for interlocking said tie bar to said end caps including resilient means associated with at least one end of said tie bar and at least one said end cap having said central receiving aperture for interconnecting said one end cap and said tie bar, whereby pressure engagement axially of said tie bar when aligned with said end cap interlocks said end caps and said tie bar to close said open ends of said sleeve with said sleeve therebetween.
