Abstract A paperboard windowed carton to display the front area of its contents is formed from a one-piece carton blank. The carton comprises a front panel, a back panel, and two opposite side panels, with the front panel having a window preferably covered with a transparent film such as cellophane. Top panels form a hanging panel and the top enclosure for the carton and bottom panels form its bottom closure. The top panels include a rectangular top flap, a rectangular hanging panel having an orifice and three free sides, and four triangular panels which, in the erected carton, form sides for the hanging panel.
