13. The container in accordance with claim 12, wherein the first side wall further comprises a third reinforcing side panel emanating from a side edge of the inner end panel of a second of the end walls, and a fourth reinforcing side panel emanating from the third reinforcing side panel and the outer end panel of the second end wall, such that the first, second, third, and fourth reinforcing side panels cooperate to define at least a double wall thickness along a length of the first side wall.

14. The container in accordance with claim 13, wherein the blank is fabricated from a corrugated paperboard material comprising a plurality of flutes extending in a direction such that the plurality of flutes in the first, second, third, and fourth reinforcing side panels are oriented substantially vertically relative to the bottom wall.

15. The container in accordance with claim 12, wherein the second reinforcing side panel is affixed between the first reinforcing side panel and the side panel.

16. The container in accordance with claim 12 further comprising a perforation line extending between the first reinforcing side panel and the inner end panel.

17. The container in accordance with claim 12 further comprising:

a first score line extending between the first and second reinforcing side panels; and

a second score line extending between the outer and inner end panel of the first end wall.

18. The container in accordance with claim 12 further comprising a cutout relief opening defined at an interface between the outer and inner end panel of the first end wall and the first and second reinforcing side panels.

19. The container in accordance with claim 18, wherein the cutout relief opening extends towards an outer edge of the inner end panel of the first end wall.

20. The container in accordance with claim 12 further comprising a top panel extending from a first edge of at least one of the opposing side panels.

21. The container in accordance with claim 12, wherein the two opposing end walls and the two opposing side walls cooperate to define at least a double wall thickness around a perimeter of the container.

22. The container in accordance with claim 12, wherein the first side wall further comprises a rollover panel in substantially face-to-face relationship with at least a portion of the first reinforcing side panel.

23. The container in accordance with claim 22, wherein the rollover panel emanates from the first side panel via a plurality of connector panels.

24. The container in accordance with claim 23, wherein each of the plurality of connector panels is oriented substantially parallel with the bottom wall.

25.
