ABSTRACT:
A packaging container is formed from preformed, rigid base and cover units of U-shaped cross-section having a generally flat bottom wall. The base unit is configured so that its side walls fit within and are embraced by side walls of the cover unit when assembled as a container. The base unit forms an end closure from first and second closure panels extending from an end of the base unit. The closure panels are separated from the base unit and each other by first and second fold lines. The base unit side walls have straight-cut corners at a juncture with the first closure panel, and the first closure panel side walls have straight-cut corners adjacent to the base unit, forming a square corner when folded. The first closure panel side walls also have straight-cut corners adjacent to the second closure panel, and the second closure panel side walls have straight-cut corners adjacent to the first closure panel, forming a square corner when folded to form the end closure. A device for cutting and embossing the packaging container is also disclosed.
