ABSTRACT:
An elongate generally-rectangular single handle opening is disposed transversely across the top panel of a sleeve-type carrier. Optionally, a generally-rectangular stress-relief score line arrangement extends transversely completely across the top panel and down into the side panels, and is centered around the handle opening. A generally-rectangular tear-stop score line arrangement extends transversely only partially across the top panel, and encircles the handle opening between the handle opening and the stress-relief score line arrangement. In this manner, tears originating at the handle opening are substantially prevented from propagating across the top panel of the carrier and compromising the structural integrity of the carrier.
