Abstract:
1. A packaging container, comprising: a embossed preformed, first unit of U-shaped cross-section having a generally flat base wall and opposing side walls, the first unit being sufficiently rigid such that the side walls maintain their U-shape relative to the base wall without external support and so as to remain upstanding relative to the base wall; and a embossed preformed, second unit of U-shaped cross-section having a generally flat base wall and opposing side walls, the second unit being sufficiently rigid such that the side walls maintain their U-shape relative to the base wall without external support and so as to remain upstanding relative to the base wall, the second unit configured so that the side walls of the first unit are fitted within and embraced by the side walls of the second unit when the first unit and second unit are assembled as a container, the first unit forming an end closure for the packaging container, formed from a first closure panel extending from and adjacent to an end of the first unit, and a second closure panel extending from and adjacent to an end of the first closure panel, the first and second closure panels each having a base wall and opposing side walls, the first unit and the first closure panel being separated from one another by a first fold line in the base wall extending between the side walls, the first closure panel and the second closure panel being separated from one another by a second fold line in the base wall extending between the side walls, the first unit side walls having straight-cut corners at a juncture with the first closure panel side walls and extending substantially to the base wall, and the first closure panel side walls having first straight-cut corners adjacent the first unit side walls and extending substantially to the base wall, the first closure panel side walls having second straight-cut corners adjacent the second closure panel side walls and extending substantially to the base wall and the second closure panel side walls having straight-cut corners adjacent the first closure panel side walls and extending substantially to the base wall, the first closure panel being configured for folding along the first fold line generally perpendicular to the first unit base wall and the second closure panel being configured for folding along the second fold line generally perpendicular to the first closure panel and generally parallel to the first unit base wall.
