ABSTRACT:
This invention relates to a paperboard blank for forming a carton. The blank comprises top, rear, bottom and front panels hingedly connected in the order named. End wall-forming flaps are hingedly connected to right and left ends of the main panels. Non-linear edges are provided on middle end flaps which define adhesive ports in cooperation with the exterior surface of inner end flaps. A single glue line is deposited or caulked along the non-linear edge to provide secure end walls for a finished carton.
