A carton provided with an integral, pivotable carrying handle on the top wall. The handle is a portion of a unitary blank of paperboard stock used to form the carton. When the carton is erected, the handle can be pivoted from a substantially flat stored position on the top wall to an upright use position for carrying the carton. The handle is formed from three overlapping panels after the blank is folded to provide a handle having superior strength.
