ABSTRACT:
A light-tight cassette, and method of making same, for enclosing and dispensing a roll of photosensitive web material. The cassette comprises a folded fiberboard housing having a plurality of housing wall portions with oppositely projecting lateral edges which define opposite sides of the housing. The plurality includes two planar wall portions that extend perpendicularly to each other to respective ends thereof which are disposed in spaced alignment to provide an opening between them. Two extruded plastic light-locking members are attached to those wall portion ends, respectively, one such member extending across the opening toward the other member to form a web exit passageway therebetween. The one member includes a resiliently flexible, inwardly projecting cantilever portion that is biased toward an opposing portion of the other member, both such portions having light-locking material thereon. A pair of molded plastic side caps are attached to the opposite sides of the housing, respectively, each cap having an inward-facing hub adapted to support a bearing core on which the roll of web material is freely rotatable to dispense such material through the web exit passageway.
