ABSTRACT:
A light tight cartridge for dispensing a light sensitive film strip wound on a spool comprises a container body having an exit port formed between spaced side walls in a transverse wall therebetween for accommodating a film strip extending outwardly of the container on a tangential film path which angularly changes relative to the container as the amount of the film on the spool is varied. A floating light seal is mounted in an exit port enclosure for shifting movement in a direction generally transverse to the film path and continuously provides a light sealing engagement with opposite surfaces of the film strip preventing outside light from entering the container body. The exit port enclosure and floating light seal cooperate to permit relative movement of the floating light seal in a direction generally normal to the path of the film and thereby accommodate different angular paths of film travel from the internal spool toward a fixed locational relationship such as an external film roller.
