ABSTRACT:
This disclosure illustrates and describes a bottom closure structure for a liquid carrying, thermoplastic coated paperboard carton or container wherein the overlapped and sealed areas are formed so as to extend in an "X"-shaped configuration across the bottom, with minimal raw edge exposure on the inside. The shapes of the four main bottom panels of the blank from which the carton is formed are such that they accommodate interdigital nesting or overlapping with respect to the bottom section of an adjacent blank prior to the cutting operation on a paperboard roll, thereby resulting in a narrower roll and, hence, a substantial paperboard savings.
