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 (14)

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 third corner assembly panel adjacent the end panel;

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

a top panel flap connected with said top panel by a fold line, said top panel flap defining a top panel flap profile; and,

a top panel flap support cutout formed in a top edge of said third corner assembly panel, said top panel support cutout having a profile that substantially matches a portion of the top panel flap profile, said top panel support cutout extending below the hinged attachment of the top panel with the side 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.
