STRAIGHT-EDGED PACKAGING CONTAINER AND DEVICE FOR FORMING SAME

摘要

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 closur e 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 pane! side wall s also have straight-cut corners adjacent to the second closure panel, and the seco nd 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.
