Abstract
Abstract A package for a roll of light-sensitive strip material which includes end covers and a circumferential cover. The circumferential cover is adhered to a leader connected to the outermost end of the strip or to the outermost end portion of the strip in the case no leader is used. The circumferential cover has a pair of side lips extending beyond the respective side edges of the strip and folded over the end covers. Each side lip has slits extending from the edge thereof toward, but terminating short of, the outer convolutions of the roll. The assembled roll and its package may be room-light loaded into exposure apparatus such as a camera, magazine, etc. with a portion of the circumferential cover extending from the roll. After the exposure apparatus has been sealed to light, the remainder of the circumferential cover may be stripped from the roll, tearing the side lips away from the rest of the circumferential covers so that successive convolutions of the strip material may be unwound from the roll.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
In a package for a roll of strip material coiled in convolutions of increasing radius and having generally flat end surfaces, the improvement comprising: an end cover for each end surface of the roll; a circumferential cover adhered to the coiled strip material for covering at least the outer most convolution of the coiled strip material with leaving the outermost end thereof uncovered, said circumferential cover having a pair of side lips extending beyond the respective side edges of the strip and folded over said end covers; and slits in said side lips extending from the edges of said side lips generally radially of the roll toward, but terminating short of, the outer convolutions of the roll.
Claim 2
Dependent Claim
117 words
In a package for a roll of strip material coiled in convolutions of increasing radius and having generally flat end surfaces, the improvement comprising: an end cover for each end surface of the roll; a circumferential cover adhered to the coiled strip material for covering at least the outer most convolution of the coiled strip material with leaving the outermost end thereof uncovered, said circumferential cover having a pair of side lips extending beyond the respective side edges of the strip and folded over said end covers; and slits in said side lips extending from the edges of said side lips generally radially of the roll toward, but terminating short of, the outer convolutions of the roll.
Claim 3
Dependent Claim
35 words
The package as recited in claim 1 wherein each of said end covers has ribs extending radially of the roll and wherein the package further includes a second end cover mounted on each end cover.
Claim 4
Dependent Claim
133 words
In a package for a roll of strip material coiled in convolutions of increasing radius and having generally flat end surfaces, the improvement comprising: a leader connected to the outermost end of the strip forming at least the outermost convolution of the roll; an end cover for each end surface of the roll; a circumferential cover adhered to said leader for covering at least the outermost convolution of the roll with leaving the outermost end of said leader uncovered, said circumferential cover having a pair of side lips extending beyond the respective side edges of the strip and folded over said end covers; and slits in said side lips extending from the edges of said side lips generally radially of the roll toward, but terminating short of, the outer convolutions of the roll.
Claim 5
Dependent Claim
133 words
In a package for a roll of strip material coiled in convolutions of increasing radius and having generally flat end surfaces, the improvement comprising: a leader connected to the outermost end of the strip forming at least the outermost convolution of the roll; an end cover for each end surface of the roll; a circumferential cover adhered to said leader for covering at least the outermost convolution of the roll with leaving the outermost end of said leader uncovered, said circumferential cover having a pair of side lips extending beyond the respective side edges of the strip and folded over said end covers; and slits in said side lips extending from the edges of said side lips generally radially of the roll toward, but terminating short of, the outer convolutions of the roll.
Claim 6
Dependent Claim
35 words
The package as recited in claim 3 wherein each of said end covers has ribs extending radially of the roll and wherein the package further includes a second end cover mounted on each end cover.
