Abstract: A carton includes a tubular body with a pair of opposed sidewalls and a pair of opposed endwalls. A closure extending from the sidewalls and endwalls includes end panels and side panels joined to the endwalls and sidewalls with hinge lines. The end panels have a discontinuous free edge which extends across a pair of free corners. A recessed edge is located between the free corners and defines a pair of U-shaped locking edge portions on either side of a generally arcuate intermediate portion. A pair of locking recesses are formed in each side panel, each recess including an arcuate edge portion spanning a generally truncated V-shaped edge portion. The recessed edge of the end panels engages the locking recesses of the side panels to lock the carton closure.
