Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
An end loaded carton for packaging a plurality of cans arranged in side by side relation, said carton comprising foldably joined top, bottom and side walls forming a tubular structure and having end closure panels, one wall of the carton being of double ply construction having inner and outer panels and being in engagement with the ends of the packaged cans, the inner ply of said one wall including a thickening panel foldably joined to an end edge of said inner ply which is spaced inwardly from the adjacent end edge of said outer ply, said thickening panel being folded into flat face contacting relation with said inner ply to form a three ply wall in engagement with the can ends.
Claim 2
Dependent Claim 121 words
An end loaded carton for packaging a plurality of cans arranged in side by side relation, said carton comprising foldably joined top, bottom and side walls forming a tubular structure and having end closure panels, one wall of the carton being of double ply construction having inner and outer panels and being in engagement with the ends of the packaged cans, the inner ply of said one wall including a thickening panel foldably joined to an end edge of said inner ply which is spaced inwardly from the adjacent end edge of said outer ply, said thickening panel being folded into flat face contacting relation with said inner ply to form a three ply wall in engagement with the can ends.
Claim 3
Dependent Claim 136 words
An end loaded carton for packaging a plurality of cans arranged in side by side relation, said carton comprising foldably joined top, bottom and side walls forming a tubular structure and having end closure panels, one wall of the carton being of double ply construction having inner and outer panels and being in engagement with the ends of the packaged cans, the inner ply of said one wall including a thickening panel foldably joined to said inner ply along a transverse fold line, said thickening panel being initially folded out of the plane of said inner ply and thereafter folded into flat face contacting relation with said inner ply due to engagement with incoming cans during loading of the carton through an end thereof to form a three ply wall in engagement with the can ends.
Claim 4
Dependent Claim 136 words
An end loaded carton for packaging a plurality of cans arranged in side by side relation, said carton comprising foldably joined top, bottom and side walls forming a tubular structure and having end closure panels, one wall of the carton being of double ply construction having inner and outer panels and being in engagement with the ends of the packaged cans, the inner ply of said one wall including a thickening panel foldably joined to said inner ply along a transverse fold line, said thickening panel being initially folded out of the plane of said inner ply and thereafter folded into flat face contacting relation with said inner ply due to engagement with incoming cans during loading of the carton through an end thereof to form a three ply wall in engagement with the can ends.
Claim 5
Dependent Claim 134 words
