ABSTRACT:
A carton construction and method of making an integral cutting edge therefor. An intermittent cut-score line is utilized at the juncture of the front and bottom main panels the cut segments of which extend into the front panel to provide a plurality of discrete teeth for the cutting edge. The end portions of each cut segment terminate approximately at the juncture of the front and bottom panels so that the space between the cut segments provide an axis for folding between the front and bottom panels in erecting the carton. Additionally, the individual teeth are stiffened by applying a coating thereto. The carton blank is formed into an open ended tube and a plurality of these tubes, in flattened condition, are stacked with the cutting teeth uppermost in which position they are coated, such as by a roller coating.
