ABSTRACT:
A carton has a plurality of side panels each connected by a fold line to one of a series of end closure flaps, there being a major flap having two oppositely located and oppositely angularly related slots canted with respect to the fold line of that flap with none of the slot edges are parallel to the fold line, and two minor flaps each having a correspondingly canted tab are adapted when the minor flaps are folded inwardly to slidably enter the slots in the major flap folded thereover and smoothly overlie the upper surface of the major flap in the slot area. Each major flap slot has upper and lower straight end edges with each inner slot end edge being straight and inclined at a small acute angle relative to a line parallel to the major flap fold line, and each minor tab has converging straight side edges with the tab edge nearer the flap fold line extending at a small acute angle relative to a line perpendicular to the fold line.
