ABSTRACT:
A thin profile carton is formed from a single blank of paperboard consisting of a plurality of side walls joined to one another to form a rectangularly shaped carton having a depth dimension from front-to-back substantially less than its width dimension with an improved ripped, carton opening scheme at the top end thereof. The top end opening feature comprises a single, substantially straight, cut and scored line of weakness in one of the top end closure flaps of the carton, which line of weakness extends completely across the end closure flap and intersects at least one fold line in said end closure flap. The fold line defines at least one carton opening tab that is an integral part of said end closure flap.
