ABSTRACT:
A carrier containing a plurality of layers of articles arranged in stacked end-to-end fashion. The carrier is fully enclosed and includes side end panel flaps which extend substantially the entire distance from the top panel to the bottom panel of the carrier to strengthen the carrier and prevent bowing of the panels. Score lines in the side end panel flaps further prevent bowing during folding. The top panel is formed by overlapping top panel flaps, the inner top panel flap including a folded-under reinforcing flap which produces an area of triple thickness between handle openings in the flaps and which extends into the end panels for additional reinforcement purposes.
