1. A method for forming a multi-panel container having an enclosed, hollow interior, said method comprising the steps of:
- forming a unitary blank of sheet material having four blank outer edges, four blank corners and four blank quadrants, said blank quadrants meeting at a location on said blank spaced inwardly from said four blank sides;
in each blank quadrant, creating a double-ended first fold line and a double-ended second fold line, both the ends of the first and second fold lines being interconnected and said first and second fold lines in each blank quadrant being spaced from one another between the connected ends thereof to define a side panel disposed completely within the blank quadrant, said first and second fold lines in each blank quadrant being disposed on opposed sides of an imaginary diagonal line extending across the blank quadrant between opposed junctures formed by adjoining blank outer edges at the blank quadrant boundary, the side panels at least partially surrounding and defining a bottom panel, said side panels and said adjoining blank outer edges defining top panels;
folding the unitary blank along all of the first fold lines located in all four quadrants thereof whereby the side panels extend upwardly from said blank bottom panel; and
folding the unitary blank along all of the second fold lines located in all four quadrants thereof whereby the top panels extend inwardly from said side panels over said bottom panel to enclose said hollow bottom interior.

- 16. A unitary blank of sheet material for forming a multi-panel container having an enclosed, bottom interior, said blank having four blank outer edges, four blank corners, and four blank quadrants, said blank quadrants meeting at a location on said blank spaced inwardly from said four blank sides, each blank quadrant having a double-ended first fold line and a double-ended second fold line, both ends of said first and second fold lines in each blank quadrant being connected and said first and second fold lines in each blank quadrant being spaced from one another between the connected ends thereof and defining a side panel disposed completely within the blank quadrant, said first and second fold lines in each blank quadrant being disposed on opposed sides of an imaginary diagonal line extending across the blank quadrant between opposed junctures formed by adjoining blank outer edges at the blank quadrant boundary, the side panels at least partially surrounding and defining a bottom panel, and said side panels and said adjoining blank outer edges defining top panels.
