Light-tightly packaged roll of light sensitive material

A light-tightly packaged roll of light-sensitive strip material wound on a hollow tubular supporting core, which comprises a generally annular opaque end cover for each end face of said roll, said end covers having their inner margins light-tightly affixed to the opposite end edges of the core and leaving the interior opening of the core unobstructed while the outer diameter thereof exceeds the diameter of said roll and thus projecting at their outer margins radially beyond the peripheral limits of the roll continuously around the roll periphery, and an opaque circumferential cover wound around at least the outermost convolution of the coiled strip material while leaving a leader section projecting outside and wound cover, said circumferential cover having a dimension parallel to the roll axis exceeding the width of said strip material to provide marginal extensions at both ends of the roll, said marginal extensions being flared angularly outwardly of said roll generally parallel to the radially projecting margins of the end voers, the mutually facing sides of said marginal extensions and radially projecting margins being adhesively sealed together.
