ABSTRACT:
A roll dispenser carton for dispensing sheet material, e.g., food wrap type sheet material. A unique cutting edge structure on the carton permits tearing off a length of the sheet material after that length has been withdrawn from the roll inside the carton. In the case of certain type sheet materials, the cutting edge structure retains the remaining free edge of the sheet material on the cutting edge after the desired sheet length has been torn from the roll. The cutting edge structure is comprised of a series of punched buds, each bud having at least two petals, that are formed in a metal sheet by punching that sheet with a piercing punch. The points of each bud's petals are turned inwardly toward the bud's axis, thereby minimizing the cutting edge's ability to scrape or scratch a user's hands or the like.
