Abstract

A blank for forming a carton is provided. The blank comprises top, rear, bottom, front and cover panels hingedly connected in the order named. End wall-forming flaps are hingedly connected to left and right ends of the main panels. A feed gate engaging notch is formed on any of the eight (8) end wall-forming flaps to avoid smearing of printing ink during the finishing operation. All score lines, offset portions, perforations and breakaway features are formed in the same direction with reference to the paperboard stock.
