Abstract: A dispenser carton for dispensing sheet material, e.g., household wrap type sheet material. A unique structure at one corner of the carton permits tearing off a length of the sheet material after that length has been withdrawn from a roll inside the carton. The carton corner is comprised of plural serrated cutting sections each of which is cut through at least one of the panels, and plural fold sections which cooperate to connect the carton's walls together at that corner, the serrated and fold sections alternating along the corner's length from one end to the other. The serrated sections are of a length and number to permit tearing of the sheet material to desired length on that carton corner, and the fold sections are of a length and number to provide structural rigidity to the carton at that corner during normal use of the tearing edge and carton so formed.

Abstract: A dispenser carton for dispensing sheet material, e.g., household wrap type sheet material. A unique cutting edge structure for the carton permits tearing off a length of sheet material withdrawn from a supply roll inside the carton, while simultaneously braking the sheet material remaining on the roll during the tearing step to prevent inadvertent withdrawal of additional sheet material. In preferred form, the cutting edge structure is comprised of an abrasive applied to the free edge of the carton's closure flap, the abrasive being on the inside face of that closure flap. After the desired sheet material length is withdrawn from the roll within the carton, the carton's cover is closed and the closure flap is manually pressured against the carton's front wall. In this attitude, the abrasive and the closure flap's leading edge cooperate to provide a cutting edge by which the free length of sheet material can be torn off the supply roll from one edge to the other.
