Abstract
A light-tight, self-contained canister and light sealing, anti-blooming tab, of generally rectangular shape, for preventing a roll of core wound photosensitive media, containable within the canister and used in a microfiche or microfilm reader-printer, from being damaged or exposed to actinic light during shipping and storage. The canister includes an open-ended, opaque tubular sleeve having an exit slot, and the sleeve is closed at both ends by opaque end caps fastened thereto. The tab includes an insertable portion joined along a fold line to an extendable portion. The insertable portion may be inserted into the exit slot and engageably wedged between the roll of core wound photosensitive media and the sleeve to prevent undesired rotation. In addition, the extendable portion of the tab is folded at the fold line along the exit slot. Further, the extendable portion includes two outer edge flaps which may be folded and inserted between the end cap outer edges and the sleeve to prevent the end portion of the media from being pulled back into the canister where it would become inaccessible. Thus, the tab light seals the exit slot and can be easily removed by grasping and pulling it.
