ABSTRACT:
A light-tight canister for a roll of photosensitive media including an opaque tubular sleeve having outer ends, a pair of identical end caps with peripheral edges configured to engage and enclose the ends of the sleeve, and a tie bar extending through the sleeve and configured for locking engagement with the end caps. The tubular sleeve includes a media exit slot extending between the outer ends and a tapered notch on each end positioned with respect to the media exit slot. Each end cap includes a media exit slot accommodating structure and a tapered tab configured to mate with a notch in the sleeve. The tab is positioned with respect to the media exit slot accommodating structure so the media exit slot accommodating structure is aligned with the media exit slot of the sleeve when the end cap is engaged with the sleeve and the tab is mated with the notch. Sloping guide walls are radially positioned on the inside surface of the end cap about a location at which the tie bar is engaged with the end cap.
