ABSTRACT:
The embodiments of the present invention provide a blank foldable material that may be configured to form a container. When formed, the container is self-locking and includes top panel assemblies that form additional bearing surfaces. The blank is configured to form a container that includes corners having multiple thicknesses. However, despite the multiple thickness of the corner assemblies, the panels are only adhered in one location per corner. The single adhesion/corner arrangement provides a multi-wall corner arrangement that is strong, yet has flexible applications. The single adhesive/corner adds vertical stacking strength and lateral stability between the panels. The unique approach of only adhering at one place per corner is a space and cost saving improvement that maintains a container integrity and usefulness.
