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.

Claims

1. A single sheet of foldable material cut and scored to define a container, comprising:

a bottom panel;

an end panel connected with the bottom panel;

a side panel connected with the bottom panel;

a first corner assembly panel adjacent the side panel;

a second corner assembly panel adjacent the first corner assembly panel;

a fourth corner assembly panel adjacent the end panel;

a third corner assembly panel extending between the second corner assembly panel and the fourth corner assembly panel; and

a top panel hingedly attached to said side panel, opposite said bottom panel,

wherein the first corner assembly panel is adhered to the side panel, and all other panels friction fit only.

2. The container of claim 1, wherein the single sheet of foldable material is formed from a cellulose-based material.

3. The container of claim 2, wherein the cellulose based material is formed from at least one of a wood pulp, straw, cotton, and bagasse.

4. The container of claim 2, wherein the cellulose based material is in the form of at least one of a fiberboard, containerboard, corrugated containerboard and paperboard.
