Abstract

In accordance with at least one aspect of this disclosure, a blank for forming a container includes a base having a first pair of opposed base edges and a second pair of opposed base edges. The blank includes two first side wall structures, each first side wall structure foldably attached to one of the first base edges and two second side wall structures, each second side wall structure foldably attached to one of the second base edges.

First claim

What is claimed is:

1. A blank for forming a container comprising:
a base having a first pair of opposed base edges and a second pair of opposed base edges;
two first side wall structures, each first side wall structure foldably attached to one of the first base edges; and
two second side wall structures, each second side wall structure foldably attached to one of the second base edges, wherein each of the second side wall structures comprises:
a first wall panel foldably attached to one of the second base edges along a first fold line,
a second wall panel foldably attached to the first wall panel configured to be overlapped with the first wall panel to form a side wall, and
a first minor end flap foldably attached to the first wall panel extending in a lateral direction from the first side wall panel, and
a second minor end flap foldably attached to the second side wall panel extending in the lateral direction from the second side wall panel, configured to overlap the first minor end flap and one of the first side wall structures in forming a corner of a container formed from the blank,
wherein a stacking tab section is defined in the first and second minor end flaps that is configured to form a stacking tab extending upright from a first side wall of the container formed from the blank with the first and second minor end flaps overlapped with one of the side wall structures to form the first side wall, wherein a first portion of the stacking tab section is formed in the first minor end flap, wherein a second portion of the stacking tab section is formed in the second minor end flap, and wherein a fold line connects the first and second portions of the stacking tab section, wherein the first and second wall panels are configured to fold along the fold line to overlap the first and second wall panels with one another to form the first wall panel to form a side wall.

2. The blank as recited in claim 1 , wherein the first and second wall panels are configured to form a first end wall adjacent to the first side wall with the corner of the container connecting between the first end wall and the first side wall.

3. The blank as recited in claim 2 , wherein the second side wall structures are configured so that there is no stacking tab extending upward from the first end wall in the container formed from the blank.

4. The blank as recited in claim 3 , wherein the first minor end flap includes a first corner panel, wherein the second minor end flap includes a second corner panel, wherein the first and second corner panels are configured to overlap and form a beveled wall connecting the first end wall to the first side wall in the container formed from the blank.

5. The blank as recited in claim 4 , wherein a portion of the stacking tab section is formed in the first and second wall panels, so in the container formed from the blank the stacking tab section forms a stacking tab extending along both sides of a fold line connecting the first sidewall and the first end wall.

6. The blank as recited in claim 1 , wherein a void separates the first and second wall panels so that in the container formed from the blank, the fold line is on a top edge of the stacking tab formed from the stacking tab section, relative to the base.

7. The blank as recited in claim 6 , wherein the second side wall structures are configured so that there is no stacking tab extending upward from the first end wall in the container formed from the blank.

8. The blank as recited in claim 7 , wherein the first minor end flap includes a first corner panel, wherein the second minor end flap includes a second corner panel, wherein the first and second corner panels are configured to overlap and form a beveled wall connecting the first end wall to the first side wall in the container formed from the blank.

9. The blank as recited in claim 8 , wherein a portion of the stacking tab section is formed in the first and second wall panels, so in the container formed from the blank the stacking tab section forms a stacking tab extending along both sides of a fold line connecting the first sidewall and the first end wall.

10. The blank as recited in claim 7 , wherein the first minor end flap is foldably connected directly to the first wall panel, and wherein the second minor end flap is foldably connected directly to the second wall panel so that in the container formed from the blank, the first end wall is foldably connected directly to the first side wall without an intervening bevel panel.

11. The blank as recited in claim 6 wherein edges of the void form top edges of the first end wall and of the first side wall below the top edge of the stacking tab, relative to the base.

12. The blank as recited in claim 1 , wherein the stacking tab section is a first stacking tab section and further comprising:
a second stacking tab section defined in the first and second wall panels, configured to form a stacking tab extending upright from a first end wall of the container formed from the blank with the corner of the container connecting between the first end wall and the first side wall.

13. The blank as recited in claim 12 , wherein the first and second stacking tab portions each fold along a fold line, wherein the fold line is interrupted between the first and second stacking tab portions by a void separating between the first and second wall panels, so that in the container formed from the blank, the fold line is on a top edge of the stacking tabs formed of the first and second stacking tab sections, relative to the base, and wherein edges of the void form top edges of the first end wall and of the first side wall below the top edges of the stacking tabs, relative to the base.

14. The blank as recited in claim 13 , wherein the first minor end flap includes a first corner panel, wherein the second minor end flap includes a second corner panel, wherein the first and second corner panels are configured to overlap and form a beveled wall connecting the first end wall to the first side wall in the container formed from the blank.

15. The blank as recited in claim 13 , wherein the first minor end flap is foldably connected directly to the first wall panel, and wherein the second minor end flap is foldably connected directly to the second wall panel so that in the container formed from the blank, the first end wall is foldably connected directly to the first side wall without an intervening bevel panel.

16. The blank as recited in claim 1 , wherein the first and second wall panels are configured to fold along a first fold line to overlap the first and second wall panels with one another to form the first wall panel to form a side wall, wherein the first fold line directly connects between the first and second wall panels to form a top edge of the side wall relative to the base in the container formed from the blank.

17. The blank as recited in claim 16 , wherein a second fold line connects first and second portions of the stacking tab section, wherein the second fold line is spaced apart farther from the base than the first fold line, so in a container formed from the blank, the second fold line forms a top edge of a stacking tab formed from the first and second portion of the stacking tab section, wherein the second fold line is above the first fold line, relative to the base.

18. A container made from a blank as recited in claim 1 , wherein each of the first side wall structures is positioned inward from the first and second wall panels.

19. A container made from a blank as recited in claim 1 , wherein each
