ABSTRACT:
A shipping carton is converted to use as a display carton using perforated lines and precut openings that together define a line circumscribing the carton. At any location at which the perforated line crosses an edge of the carton of another perforated line, a precut opening provides a clean separation. Additionally, no section of the perforated lines parallels an adjacent fold line.
