Abstract
Abstract The Cassette Assembly has a prominent out-feeding section coupled to and projecting from a sheet materials confining section for nestably mating with a trough therefor formed in a sheet materials dispenser. The trough has diminishing dimensions inwardly thereof, and an inner portion with a specific width. The out-feeding section of the Cassette Assembly is so constructed as to have a complementary, i.e., substantially equal, overall width dimension across a portion thereof to form a light-sealing, light-tight, fit of such portion with the inner portion of the trough. In a first embodiment thereof, the out-feeding section of the Cassette Assembly defines the light-tight, sealing width dimension of the portion thereof of its basic, plastic construction. In other embodiments, the sealing width dimension is formed, effectively, by the expedient of fixing strips of light-sealing material on the outer walls of the out-feeding section of the Cassette Assembly.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
185 words
For use with a rolled sheet materials dispenser having a cassette-receiving trough with a first, innermost length of a given dimension, and a second, outermost length of another dimension which is greater than said given dimension, and having a first, outermost portion with a width of a prescribed dimension, and a second, inner portion with a width of a specific dimension which is smaller than said prescribed dimension, a cassette assembly, comprising: a first, rolled sheet materials-confining section; and a second, rolled sheet materials-out-feeding section coupled to said first section; wherein said second section has a trough-engaging portion with means for (a) forming said trough-engaging portion with an overall, effective width of a dimension which is substantially equal to such specific dimension of such a sheet materials dispenser trough, and (b) defining thereat, upon said out-feeding section being mated with such trough, a light-tight, sealing fit of said trough-engaging portion with such second, inner portion of such trough; said means comprise substantially parallel walls projecting from said first section; and at least one strip of material of light-sealing property adhered to one of said walls.
Claim 2
Dependent Claim
185 words
For use with a rolled sheet materials dispenser having a cassette-receiving trough with a first, innermost length of a given dimension, and a second, outermost length of another dimension which is greater than said given dimension, and having a first, outermost portion with a width of a prescribed dimension, and a second, inner portion with a width of a specific dimension which is smaller than said prescribed dimension, a cassette assembly, comprising: a first, rolled sheet materials-confining section; and a second, rolled sheet materials-out-feeding section coupled to said first section; wherein said second section has a trough-engaging portion with means for (a) forming said trough-engaging portion with an overall, effective width of a dimension which is substantially equal to such specific dimension of such a sheet materials dispenser trough, and (b) defining thereat, upon said out-feeding section being mated with such trough, a light-tight, sealing fit of said trough-engaging portion with such second, inner portion of such trough; said means comprise substantially parallel walls projecting from said first section; and at least one strip of material of light-sealing property adhered to one of said walls.
