ABSTRACT:
This disclosure illustrates and describes a bottom closure structure for a liquid carrying, thermoplastic coated paperboard carton or container wherein the shapes of the four main bottom panels of the blank from which the carton is formed are such that they provide bottom panel side score lines which are sufficient in length to support the panels during the folding and tucking operation changing the flat blank into a finished carton bottom closure. In one embodiment of the invention, complete interdigital nesting or overlapping of adjacent blanks is provided for. As such, the cutting operation on a paperboard roll may be accomplished with an uninterrupted cut, without any resultant paperboard scrap being produced therebetween.
