Abstract
A light-tight cassette for photographic material, which has the form of a box (11) having wall portions (26,27) defining an exit slot (15) for material drawn from a roll (19). The exit slot has light-sealing means which is formed by cooperating flexible (31,32) lips, and generally rigid ribs (36,37) which limit the deflection of the lips. The box and the flexible lips are preferably made by the co-extrusion of suitable plastics. The cassette has the advantage that a satisfactory light-tightness of the dispenser slot can be obtained with very flexible lips, so that damage to the film by frictional contact with the lips is avoided while an effective light seal is assured for all paths of the material through the slot.
