Abstract

A blank assembly for forming a container includes a body blank that includes a bottom panel and two opposing side panels. The side panels are configured to at least partially form two opposing side walls of the container. The blank assembly also includes at least two end blanks. Each end blank is configured to form at least a portion of an end wall of the container. Each end blank includes a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series along preformed, parallel fold lines. The first inner corner panel is configured to extend obliquely between a side wall and an end wall. The first reinforcement panel is configured to extend from the first inner end panel inwardly towards an interior cavity of the container.

First claim

What is claimed is:

1. A blank assembly for forming a container, the blank assembly comprising:
a body blank comprising a bottom panel and two opposing side panels, each of the two side panels extending from one of two opposing side edges of the bottom panel, the two side panels configured to at least partially form two opposing side walls of the container; and
at least two end blanks, each end blank configured to form at least a portion of one of two opposing end walls of the container, each end blank comprising a first inner side panel, a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series, in the order recited, along a plurality of preformed, parallel fold lines,
wherein the first inner side panel is configured to couple to one of the two opposing side panels, and the first inner corner panel is configured to extend obliquely between one of the side walls and one of the end walls, and the first reinforcement panel is configured to extend from the first inner end panel inwardly towards an interior cavity of the container, and the second reinforcement panel is configured to extend from the second inner end panel inwardly towards the interior cavity, and the first inner end panel and the second inner end panel together form said at least portion of said one of two opposing end walls when the container is formed.

2. The assembly in accordance with claim 1 , wherein the first and second reinforcement panels are configured to be oriented at an oblique angle relative to each other when the container is formed.

3. The assembly in accordance with claim 1 , wherein the first and second reinforcement panels are configured to be oriented in face-to-face contact with each other when the container is formed.

4. The assembly in accordance with claim 1 , wherein each end blank further comprises a locking tab extending from a top edge of at least one of the first and second inner end panels.

5. The assembly in accordance with claim 4 , wherein the body blank comprises a top panel extending from a top edge of at least one of the two opposing side panels, the top panel comprising a locking tab receiving slot defined therein and sized for engagement with the locking tab when the container is formed.

6. The assembly in accordance with claim 1 , wherein a height of the first and second inner end panels and the first and second reinforcement panels is configured to be substantially equal to a height of the two side panels when the container is formed.

7. The assembly in accordance with claim 1 , wherein the body blank comprises a bottom flap extending from an end edge of the bottom panel, the bottom flap configured to couple to the first and second inner end panels of one of the end blanks when the container is formed.

8. The assembly in accordance with claim 1 , wherein the body blank comprises a side flap extending from a side edge of at least one of the two opposing side panels, the side flap configured to couple to one of the first and second inner end panels of one of the end blanks when the container is formed.

9. A container formed from a body blank and at least two end blanks of sheet material, the container comprising:
a bottom wall comprising a bottom panel of the body blank;
two opposing side walls emanating from opposing side edges of the bottom wall;
two opposing end walls each formed at least in part from a respective one of the two end blanks, each end blank comprising a first inner side panel, a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series, in the order recited, along a plurality of preformed, parallel fold lines; and
wherein the first inner side panel is coupled to one of the two opposing side walls, and the first inner corner panel forms an inner miter wall that extends obliquely between one of the side walls and one of the end walls, and the first reinforcement extends from the first inner end panel inwardly towards an interior cavity of the container, and the second reinforcement panel extends from the second inner end panel inwardly towards the interior cavity, and the first inner end panel and the second inner end panel each form at least a portion of one of said opposing end walls.

10. The container in accordance with claim 9 , wherein the first and second reinforcement panels are oriented at an oblique angle relative to each other.

11. The container in accordance with claim 9 , wherein the first and second reinforcement panels are oriented in face-to-face contact with each other.

12. The container in accordance with claim 9 , wherein each end wall comprises a locking tab extending at least partially from a top edge of at least one of the first and second inner end panels.

13. The container in accordance with claim 12 , further comprising a top panel emanating from a top edge of at least one of the two opposing side walls, the top panel comprising a locking tab receiving slot defined therein and sized for engagement with the locking tab.

14. The container in accordance with claim 9 , wherein a height of the first and second inner end panels and the first and second reinforcement panels is substantially equal to a height of the two side walls.

15. The container in accordance with claim 9 , wherein the first end wall further comprises a bottom flap emanating from an end edge of the bottom wall, the bottom flap coupled to the first and second inner end panels of the first end wall.

16. The container in accordance with claim 9 , wherein the first end wall comprises a side flap emanating from a side edge of one of the side walls, the side flap coupled to one of the first and second inner end panels of the first end wall.

17. A method of forming a container from a body blank and at least two end blanks of sheet material, each end blank comprising a first inner side panel, a first inner corner panel, a first inner end panel, a first reinforcement panel, a second reinforcement panel, and a second inner end panel coupled together in series, in the order recited, along a plurality of preformed, parallel fold lines, said method comprising:
rotating a bottom panel and two opposing side panels of the body blank about a plurality of fold lines of the body blank to at least partially form a bottom wall and two opposing side walls; and
rotating the first inner corner panel and the first and second reinforcement panels of each end blank with respect to the first and second inner end panels of the respective end blank about plurality of preformed, parallel fold lines of the respective end blank; and
coupling the first and second inner end panels of each end blank to the body blank to form two opposing end walls of the container, such that the first inner side panel is coupled to one of the two opposing side walls, such that the first inner corner panel extends obliquely between one of the side walls and one of the end walls, such that the first reinforcement panel extends from the first inner end panel inwardly towards an interior cavity of the container, such that the second reinforcement panel extends from the second inner end panel towards the interior cavity, and such that the first inner end panel and the second inner end panel each form at least a portion of one of the two opposing end walls.

18. The method in accordance with claim 17 , wherein rotating the first inner corner panel and the first and second reinforcement panels comprises orien
