ABSTRACT:
A cassette for light-tightly holding and dispensing a roll of web material, e.g. photographic film, which has a peripheral dispensing slot in its shell for passage of the web therefrom, which slot is formed by generally radially directed re-entrant lips lined with light-sealing strips to seal the slot against penetration by light, the sealing strips being adhered to the mutually facing surfaces of the lips by layers of adhesive on their backsides, preferably a pressure-sensitive adhesive, wherein the innermost edge of each of the adhesive layers is in a radially outwardly retracted position relative to the innermost edge of the associated sealing strip, leaving a short inner marginal portion of the sealing strip free of adhesive and overlying the inner edge of the adhesive layer to conceal and shelter the adhesive edge against possible contact with the exiting web. The non-adhered inner margin, and preferably a short outermost portion of each sealing strip as well, is reinforced to increase its stiffness, as by means of a coating of a polymer.
