Abstract

In accordance with the present invention, a carton for containing and protecting a single, wedge-shaped piece of dessert-type pie is provided. The carton comprises generally parallel, triangular top and bottom panels each having a base edge and converging side edges. A trapezoidal rear wall is foldably coupled to the base edges and extends between the top and bottom panels. An inner side wall panel is foldably coupled to each of the converging edges of the bottom panel and extends generally straight upwardly therefrom. An outer side wall panel is foldably connected to each of the converging edges of the top panel and extends generally straight downward therefrom. The outer side panels are closely adjacent to, overlying and affixed along one edge to the inner side wall panels. Each outer side wall panel has an opening structure comprised of a generally central, deflectable, finger-receiving opening tab and a line of weakness generally collinear with the opening tab. The line of weakness includes two spaced lines of intermittent incisions which diverge from said opening tab at an angle with respect to one another in the direction of the ends of said outer side wall panels. The invention also encompasses a flat blank for forming into the carton and another embodiment wherein the opening structure includes a generally central, finger-operated opening edge and lines of weakness extending from the opening edge.
