A packaging container is formed from a single preformed, rigid unit of U-shaped cross-section having a generally flat bottom wall. The unit forms t wo end closures from first and second closure panels extending from both ends of a main body portion. The closure panels are separated from the main body portion an d each other by first and second fold lines. The main body side walls have straight - cut corners at junctures with the first closure panels, and the first closure panels side walls have straight-cut corners adjacent to the main body, forming square corners when folded. The first closure panels side walls also have straight-cut corners adjacent to the second closure panels, and the second closure panels side walls have straight-cut corners adjacent to the first closure panels, forming square corners when folded to form the end closures. |
