Abstract
Abstract A dispenser carton for use in dispensing sheet material from a roll contained within the carton comprises bottom, rear, front, and end panels joined to one another to form a hollow carton body open at its top. One edge of a top panel is hingedly joined to the upper edge of the rear panel so as to overlie the top of the carton and its opposite edge is joined to a flap which partially overlies the front panel. At the juncture between the front and bottom panels is a gap or series of gaps defining two spaced apart edges both of which carry an abrasive adhesive which forms tearing means for sheet material dispensed from the carton.
