  • Light-tight package with circumferentially perforated end discs
    Patent number: 6126006
    Abstract: A light-tight package for a roll (1) of light sensitive material has a central core (4) around which the material is wound, a flexible opaque leader (6) having a leading end attached to the outermost end of the material and a pair of flexible end discs (7,8) covering each end of the roll. Each end disc has an outer diameter greater than the outer diameter of the roll to provide peripheral portions which are folded axially inwardly against the outer surface of the roll. A concentric ring of perforations is provided within the peripheral portion to control the tear and ensure that any portions of material left by the tear will not interfere with rewinding of the roll.
