Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 246 words
A seal-end carton of rectangular cross-section comprising alternating side, front and back panels and provided with an easily opened end closure, said closure comprising an inner major flap articulated to the front panel, an outer major flap articulated to the back panel and dust flaps articulated to the side panels, the dust flaps being located intermediate the inner and outer major flaps, the front panel having a line of weakness therein defining a removable portion contiguous the line of articulation along which said inner major flap is attached, said line of weakness extending to opposite ends of said line of articulation, the dust flaps each having a line of weakness extending thereacross from one side to the other with the major portion thereof generally parallel to and spaced from the line of articulation of the dust flap, said line of weakness on each dust flap commencing at the adjacent end of said inner major flap line of articulation and extending obliquely, distally, therefrom, the end edges of said inner major flap being generally aligned with the lines of weakness in the dust flaps, an extension attached to the distal end of the outer major flap, said extension being adapted and sized to overlie the line of weakness defining said removable portion of said front panel, said extension being adhesively attached to said removable portion, the ends of said dust flaps distal of the lines of weakness being adhesively attached to the inner and outer major flaps.
Claim 2
Dependent Claim 246 words
A seal-end carton of rectangular cross-section comprising alternating side, front and back panels and provided with an easily opened end closure, said closure comprising an inner major flap articulated to the front panel, an outer major flap articulated to the back panel and dust flaps articulated to the side panels, the dust flaps being located intermediate the inner and outer major flaps, the front panel having a line of weakness therein defining a removable portion contiguous the line of articulation along which said inner major flap is attached, said line of weakness extending to opposite ends of said line of articulation, the dust flaps each having a line of weakness extending thereacross from one side to the other with the major portion thereof generally parallel to and spaced from the line of articulation of the dust flap, said line of weakness on each dust flap commencing at the adjacent end of said inner major flap line of articulation and extending obliquely, distally, therefrom, the end edges of said inner major flap being generally aligned with the lines of weakness in the dust flaps, an extension attached to the distal end of the outer major flap, said extension being adapted and sized to overlie the line of weakness defining said removable portion of said front panel, said extension being adhesively attached to said removable portion, the ends of said dust flaps distal of the lines of weakness being adhesively attached to the inner and outer major flaps.
Claim 3
Dependent Claim 41 words
The carton of claim 1 in which the ends of said inner major flap are trimmed by cutting out portions shaped to match the portion of the adjacent dust flap which is intermediate its line of weakness and line of articulation.
Claim 4
Dependent Claim 35 words
The carton of claim 2 in which the major portions of said lines of weakness across the dust flaps are spaced at least about 174 inch from the lines of articulation of the dust flaps.
