Abstract

A blank for forming a reinforced container is provided. The blank includes a bottom panel comprising opposing end edges, opposing side edges, and at least one miter edge connecting one of the end edges to an adjacent side edge of the opposing side edges. The blank further includes a pair of opposing end panels coupled to the bottom panel, a pair of opposing side panels coupled to the bottom panel, and a reinforcing panel assembly coupled to at least one of one of the end panels and one of the side panels for reinforcing a corner of the container.

First claim

What is claimed is:

1. A blank for forming a reinforced container, the blank comprising:
a bottom panel comprising opposing end edges, opposing side edges, and at least one first miter edge connecting one of the end edges to an adjacent side edge of the opposing side edges;
a pair of opposing end panels coupled to the bottom panel;
first and second opposing side panels coupled to the bottom panel, wherein each side panel includes an interior surface and an exterior surface;
a pair of opposing top panels coupled to the pair of opposing side panels;
an outer reinforcing panel assembly comprising a first overlap panel coupled to one of the top panels, a second overlap panel, and a miter panel coupled between the first and second overlap panels; and
a cutout defined between the outer reinforcing panel assembly and a first side edge of the first side panel, wherein the second overlap panel is positionable within the cutout;
wherein the second overlap panel is substantially coplanar to the first side panel when the container is formed, wherein when the container is formed a free edge of the second overlap panel is positioned adjacent to the first side edge of the first side panel.

2. The blank of claim 1 , further comprising an inner reinforcing panel assembly comprising a corner panel and a minor panel.

3. The blank of claim 2 , wherein the minor panel is coupled to the interior surface of the first side panel when the container is formed.

4. The blank of claim 2 , wherein the second overlap panel and the minor panel are substantially congruent.

5. The blank of claim 2 , wherein the minor panel and the second overlap panel are adjacent.

6. The blank of claim 2 , wherein the corner panel and the miter panel are substantially congruent.

7. The blank of claim 2 , wherein the inner reinforcing panel assembly is coupled to one of the end panels.

8. The blank of claim 2 , wherein the free edge of the second overlap panel is configured to be aligned with a side edge of the minor panel when the container is formed.

9. The blank of claim 8 , wherein the aligned side edge of the minor panel is a free edge.

10. A method of forming a reinforcing container from a blank of sheet material, the blank including
(i) a bottom panel comprising at least one miter edge connecting adjacent edges of the bottom panel,
(ii) a pair of opposing end panels coupled to the bottom panel,
(iii) a pair of opposing side panels coupled to the bottom panel, wherein each side panel includes an interior surface and an exterior surface,
(iv) a pair of opposing top panels coupled to the pair of opposing side panels,
(v) a reinforcing panel assembly for reinforcing a corner of the container, the reinforcing panel assembly comprising

an outer reinforcing panel assembly comprising a first overlap panel coupled to one of the top panels, a second overlap panel, and a miter panel coupled between the first and second overlap panels, and
(vi) a cutout defined between the reinforcing panel assembly and a first side edge of a first side panel of the pair of opposing side panels,

the method comprising:
rotating the pair of end panels toward the bottom panel to form a pair of opposing end walls;
rotating the pair of side panels toward the bottom panel to at least partially form a pair of opposing side walls;
rotating the top panels toward the side walls and the bottom panel to form a pair of opposing top walls; and
rotating the reinforcing panel assembly to form a reinforcing corner assembly such that the second overlap panel is positioned within the cutout to further form a first side wall of the pair of opposing side walls, wherein when the second overlap panel is positioned within the cutout a free edge of the second overlap panel is positioned adjacent to the first side edge of the first side panel.

11. The method of claim 10 , wherein the reinforcing panel assembly further comprises an inner reinforcing panel assembly including a corner panel and a minor panel, the method further comprising rotating the reinforcing panel assembly to form the reinforcing corner assembly such that the free edge of the second overlap panel is aligned with a free end edge of the minor panel.

12. The method of claim 10 , further comprising coupling the minor panel to the interior surface of the first side panel.
