ABSTRACT:
A folding paperboard carton including self-positioning, self-locking bottom wall panel structure, and mutually confronting, first side wall panels connected by mutually confronting hinged second side wall panels. The bottom wall panel structure a first bottom wall panel hinged to one of the confronting first side wall panels, and a second bottom wall hinged to the other of the confronting first side wall panels. The first bottom wall panel includes tab means affixed thereto, in the folded mode of the carton, by a line of weakness, and adhered to at least one of the side wall panels excluding the side wall panel to which the second bottom wall panel is hinged. Construction and arrangement is such that unfolding the carton to set-up mode moves the confronting first side wall panels apart, pivots the first bottom wall panel to tear it from the tab means, and presents the latter for abutting, locking engagement with the second bottom wall panel upon its pivotation to substantially coplanar relationship with the first bottom wall panel, thereby to establish and maintain set-up mode of the carton.
