Abstract: A disposable single-service cup dispenser carton is disclosed. The carton is fabricated from a blank of flexible sheet material which is pre-cut and scored to define panel enclosure portion to permit the blank to be folded and erected into a tubular carton which can be collapsed during shipping and which can be folded when erected to enclose a stack of nested cups. The carton includes a dispensing panel connected intermediate side panels having pre-cut portions and perforations which delineate a tear line forming the boundary of a dispensing opening. The portion of the end panel circumscribed by the tear line is removable to permit the withdrawal of a cup from a nested stack of cups enclosed by the carton. The dispensing opening is characterized by a substantially circular edge interrupted by a plurality of radially projecting tabs which are circumferentially spaced relative to each other around the periphery of the dispensing opening.
