A carton constructed to permit the contents to be poured out over an upper corner. The top panel includes a fold line about which a corner closure flap pivots. The corner flap includes a flange formed by tear lines in portions of the adjacent side and end panels. Additional layers of material in face-to-face contact with the inner surface of the side and end panels in the area of the closure flap provide edges over which the contents are poured. The closure flap fits tightly over the additional layers to hold it in place after it has been reclosed.
