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 A unique cutting edge structure for the carton permits tearing off a length of sheet material withdrawn from a supply roll inside the carton, while simultaneously braking the sheet material remaining on the roll during the tearing step to prevent inadvertent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 After the desired sheet material length is withdrawn from the roll within the carton, the carton's cover is closed and the closure flap is manually pressured against the carton's front wall.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. Also in this use attitude, the abrasive on the closure flap's inside face cooperates with the carton's front wall to aid in preventing inadvertent withdrawal of additional sheet material from the carton as the free length is torn off the supply roll.
