ABSTRACT:
A carton having a tubular body with a pair of opposed sidewalls and a pair of opposed endwalls, with end panels and side panels for a closure extending therefrom. At least one end panel is hinged to an endwall and has a free edge defining a pair of spaced notches with a retention flap therebetween, thereby forming a pair of locking tabs, one at each free corner of the end panel. At least one hinged tab is struck out from each side panel. The hinged tab includes a tab hinge line and a double-ended severing line extending to spaced apart portions of the tab hinge line so as to form a tab which is swingable out of the plane of the side panel, thereby exposing a locking edge of the side panel formed by the severing line. The locking tabs of the end panel deflect the hinge tabs into the interior of the carton to form recesses in the side panels into which the locking tabs are inserted so that the locking edge of the tab engages the locking edge of the side panel.
