An opaque cartridge (10) for storing and dispensing light sensitive web materials (22) from a roll includes a box (18) defining a right angular sexahedron and made up of a top section (40) and a bottom section (42) hingedly connected to each other at an upper rear edge of the box (18) and providing a straight light-tight exit slot (20) at a lower front edge of the box (18), and a spool (12) consisting of a cylindrical hub (14) on which the web material (22) is wound and a pair of discoid end flanges (16) concentric with the hub (14). The hub (14) is rotatably mounted in openings provided in split end walls (30, 31) of the box (18). Light blocking and trapping flanges, baffles, plates, ledges, bars, recesses, and light steps are provided in conjunction with the hinge connection between the top and bottom box sections (40, 42), the mating connections between the top and bottom end walls (50, 60, 52, 62), and along the edge of the box providing the exit slot (20) to the end that no light can enter the chamber provided by the box (18) and spool (12) of the cartridge. <IMAGE> |
