Claim 5

A container, as set forth in claim 2, including second and third weakened lines of severance, each beginning from a separate end of said first weakened line of severance and extending downwardly a distance toward the edge of its respective roof panel.

Claim 6

A paperboard blank for forming a container of rectangular formation and having a gable top, said blank being formed with laterally spaced-apart score lines extending vertically from the lower to the upper edge of the blank, a score line extending traversely of the blank in downward spaced relation to the upper edge thereof, said latter score line, in conjunction with said vertically extending score lines, defining opposed front and rear sidewall panels and opposed end wall panels, a second transversely extending score line arranged intermediate the upper edge of said blank, and said first traversely extending score line and defining, in conjunction therewith, and with said vertically extending score lines, a front roof panel surmounting said front sidewall panel, a rear roof panel surmounting said rear sidewall panel, and an area surmounting each of said end wall panels, each of said areas being provided with converging score lines inclining upwardly from said first traverse score line to said second traverse score line and defining in each of said areas a first and second triangular end closure panel and a pair of triangular foldback panels hinged to the triangular end closure panel, said second traversely extending score line, in conjunction with said vertically extending score lines, defining ridge panels surmounting said front and rear roof panels and each pair of said foldback panels, the first triangular end closure panel and its associated pair of triangular foldback panels forming a rectangular end closure panel having a weakened line of severance lying solely within the upper portion thereof and extending traversely of said first rectangular end closure panel and terminating at its ends in spaced relation to the side edges of said rectangular end closure panel, wherein the improvement comprises: second and third weakened lines of severance, each beginning from a separate end of said first weakened line of severance and extending downwardly a distance.

Claim 7

A paperboard blank for forming a container of rectangular formation and having a gable top, said blank being formed with laterally spaced-apart score lines extending vertically from the lower to the upper edge of the blank, a score line extending traversely of the blank in downward spaced relation to the upper edge thereof, said latter score line, in conjunction with said vertically extending score lines, defining opposed front and rear sidewall panels and opposed end wall panels, a second transversely extending score line arranged intermediate the upper edge of said blank, and said first traversely extending score line and defining, in conjunction therewith, and with said vertically extending score lines, a front roof panel surmounting said front sidewall panel, a rear roof panel surmounting said rear sidewall panel, and an area surmounting each of said end wall panels, each of said areas being provided with converging score lines inclining upwardly from said first traverse score line to said second traverse score line and defining in each of said areas a first and second triangular end closure panel and a pair of triangular foldback panels hinged to the triangular end closure panel, said second traversely extending score line, in conjunction with said vertically extending score lines, defining ridge panels surmounting said front and rear roof panels and each pair of said foldback panels, the first triangular end closure panel and its associated pair of triangular foldback panels forming a rectangular end closure panel having a weakened line of severance lying solely within the upper portion thereof and extending traversely of said first rectangular end closure panel and terminating at its ends in spaced relation to the side edges of said rectangular end closure panel, wherein the improvement comprises: second and third weakened lines of severance, each beginning from a separate end of said first weakened line of severance and extending downwardly a distance.

Claim 8

A paperboard blank for forming a container of rectangular formation, as set forth in claim 4, including first and second score lines located in each roof panel adjacent the first rectangular end closure having the weakened lines of severance, each first and second score line beginning at a point located on its respective roof panel, overlying its respective triangular foldback panel when folded and sealed to form a gable top container, spaced from the edge of the roof panel, and a distance from the ridge panel and the respective sidewall of the roof panel, each first score line extending from its respective beginning point a distance upwardly and toward the roof panel edge, and each second score line extending from its respective beginning point downwardly and a distance toward its respective sidewall when folded and sealed to form a gable top container.
