Claim 7

The invention defined by claim 3, together with means in said tear panel adjacent to said tear-facilitating score line and between said corners, for facilitating initiation of the tear.

Claim 8

The invention of claim 3, in which said tear-facilitating score line is for the most part perforated, but is a continuous cut at each of said corners.

Claim 9

The invention of claim 3, in which said tear-facilitating score line is for the most part perforated, but is continuous across the intersection thereof with the score line between said third and fourth body panels.

Claim 10

The invention of claim 3, in which the score line between said fourth panel and said closure tab includes completely cut end portions extending towards said axis as far as said tear-facilitating score line.

Claim 11

The invention of claim 3, in which the portion of said tear-facilitating score line extending across said fourth body panel combines through-perforations with a continuous cut of a portion of the thickness of said blank.

Claim 12

In a carton having a front panel, a top panel, a back panel, and a closure tab for securing the back of the top panel to the top of said back panel, a tear panel defined by a first tear-facilitating line extending horizontally across said front panel and a pair of further tear-facilitating lines extending upward from the opposite ends of the first line to the upper limit of said front panel and thence across the entire top panel to its intersection with the back panel, and means coacting between said back panel and said closure tab for facilitating neat removal of said closure tab with said tear panel.

Claim 13

In a carton having a front panel, a top panel, a back panel, and a closure tab for securing the back of the top panel to the top of said back panel, a tear panel defined by a first tear-facilitating line extending horizontally across said front panel and a pair of further tear-facilitating lines extending upward from the opposite ends of the first line to the upper limit of said front panel and thence across the entire top panel to its intersection with the back panel, and means coacting between said back panel and said closure tab for facilitating neat removal of said closure tab with said tear panel.

Claim 14

The invention according to claim 9, in which said pair of further tear-facilitating lines are less resistant to tearing across said top panel than they are across said front panel.

Claim 15

A carton blank symmetrically arranged on opposite sides of a longitudinal axis or center line and having both longitudinal and transverse fold-facilitating score lines which define in sequence a first, back body panel; a second, bottom body panel; a third, front body panel; and a fourth, top body panel; all panels having transversely extending end flaps; a closure tab; and a tear panel, defined by a tear facilitating score line, with smaller transverse extent than that of said body panels between the longitudinal fold facilitating score lines, and centered within said third and fourth body panels about said center line, said tear panel being defined by a Tear-facilitating score line extending in part the width of the tear panel transversely in the fourth body panel at a position short of the score facilitating line between said closure tab and said fourth or top body panel, the tear panel being further defined by a pair of longitudinal lines from the ends of the transverse tear lines that extend in the direction of the center line across the remainder of said top body panel, then across the fold facilitating score line between said fourth and third body panels and longitudinally across the major portion of the third panel, and the ends of the longitudinally extending tear lines thence being connected by a tear line transversely of said third panel.
