Abstract
Tear strip structure for the relatively narrow side wall of a relatively flat rectangular paperboard carton. The side wall is defined by an inner folded closure flap and an outer flap folded thereover. The outer flap has a line of weakness extending along its length, between and parallel to its fold line and its free edge. The inner flap has a first cut score line defining its fold line and a second cut score line coincident with the line of weakness of the outer flap. The region of the outer flap overlying the region of the inner flap between the cut score lines is adherent to the latter region and defines a tear strip, an end portion of which is non-adherent and functions as a tab by which the strip may be grasped and torn away, separating the plies of the underlying closure flap between the cut score lines in achievement of removal of the tear strip in predictable, controlled manner.
