Abstract
A light-tight enclosure (10) for storing and dispensing a roll of photosensitive web material (32) directly in a cooperating apparatus without need for an auxiliary cartridge. The web is wound about a cylindrical core (34, 68, 74) having flush, closed opposite ends (36) and an axial bore (38) in each end. The core may be closed by integral ends or by fullfitting plugs (76). The enclosure comprises a flexible opaque bag (12) with opposite sidewalls (16) extending between opposing rearward and forward portions (18 and 20) and between opposing upper and lower portions (22 and 24). Each sidewall has a central aperture therein congruent with each core end. The rearward portion defines a closable opening for receiving the roll. A shallow neck portion (26) projects from the forward portion to an end (28) thereof defining an exit slot (30) for dispensing the web material. Mounting pins (40) are disposed in both axial bores and extend through the apertures in the sidewalls, and flanges (44) on the shafts (42) of the pins outside the bag capture the sidewall material light-tightly between the flanges and the ends of the cores. The mounting pins have shouldered portions (48) outboard of the f…
