Abstract

A container including a bottom portion and a plurality of peripheral wall portions extending from the bottom portion and defining an interior area of the container. At least one peripheral wall portion has an inner surface including a feature defining an inner ledge extending into the interior area, the inner ledge being located between the bottom portion and an upper edge of the container. The at least one peripheral wall portion has an outer surface including a feature defining an outer ledge located between the bottom portion and the upper edge of the container. The inner ledge is positioned to engage the outer ledge of a similarly-configured container whereby a spacing between a stack of nested containers is defined by the outer ledge of the similarly-configured container seated on the inner ledge of the container.

First claim

What is claimed is:

1. A container comprising:
a bottom portion defining a base of the container;
a plurality of peripheral wall portions extending from the bottom portion and defining an interior area of the container;
an upper edge of the container defined by edges of the peripheral wall portions distal from the bottom portion;
at least one peripheral wall portion comprising a first peripheral wall portion comprising a first wall panel and a first flap in contact with the wall panel, one of the flap or the wall panel including a feature defining an inner ledge extending into the interior area, the inner ledge located between the bottom portion and the upper edge of the container;
the other of the wall panel or flap including a feature defining an outer ledge located between the bottom portion and the upper edge of the container; and
the inner ledge being positioned to engage an outer ledge of a similarly-configured container whereby a spacing between a stack of nested containers is defined by the outer ledge of the similarly-configured container seated on the inner ledge of the container;
wherein the first wall panel defines a side wall panel hingedly joined to the bottom portion, the outer ledge is defined at an edge formed by a cut-out area on the side wall panel, the cut-out area being defined by a first cut-out edge extending from a longitudinal edge of the bottom portion, a second cut-out edge extending from and oriented generally perpendicular to the first cut-out edge and an open side defined by an imaginary line extending from a lateral edge of the bottom portion, the edge formed by the cut-out area facing toward the bottom portion.

2. The container as set forth in claim 1 , wherein the bottom portion is generally planar, and the peripheral wall portions each extend at an obtuse angle with respect to a plane defined by the bottom portion.

3. The container as set forth in claim 1 , wherein the flap has a wall thickness and the inner ledge has a thickness defined by the flap wall thickness.

4. The container as set forth in claim 1 , wherein the flap defines an inner flap forming a portion of the first peripheral wall portion.

5. The container as set forth in claim 4 , wherein the inner ledge is defined on an edge of the inner flap at a junction with the wall panel, the edge of the inner flap facing away from the bottom portion.

6. The container as set forth in claim 5 , wherein the inner flap overlaps and is adhesively attached to the side wall panel.

7. The container as set forth in claim 6 , wherein the inner flap is hingedly attached to a further peripheral wall portion located adjacent to the first peripheral wall portion.

8. The container as set forth in claim 6 , wherein the inner flap overlaps the cut-out area and forms a portion of an outer surface of the first peripheral wall portion at the cut-out area, and the inner flap fits within a cut-out area of the similarly-configured container when the similarly-configured container is nested within the container.

9. The container as set forth in claim 1 , wherein the wall panel defines an inner flap hingedly attached to the bottom portion, and the first flap is defined by at least one connection flap hingedly attached to at least one further peripheral wall portion located adjacent to the first peripheral wall portion.

10. The container as set forth in claim 9 , wherein the at least one connection flap overlaps the inner flap, and the outer ledge is defined by an edge of the at least one connection flap that faces toward the bottom portion.

11. The container as set forth in claim 10 , wherein the at least one connection flap comprises a pair of connection flaps attached to respective opposing further peripheral wall portions located adjacent to the first peripheral wall portion.

12. The container as set forth in claim 1 , including a flange at the upper edge of the container, the flange formed by flange portions hingedly attached to each of the plurality of peripheral wall portions, wherein each peripheral wall portion includes a flange portion having tabs extending from opposing ends, wherein the tabs extend along portions of respective adjacent peripheral wall portions to form overlapping joints with flange portions of the respective adjacent peripheral wall portions.

13. The container as set forth in claim 1 , wherein the wall panel and the flap have substantially the same thickness.

14. The container as set forth in claim 1 , wherein the first cut-out edge is generally perpendicular to the longitudinal edge of the bottom portion.

15. A container formed from a one-piece blank of sheet material, the container comprising:
a generally planar bottom portion defining a base of the container;
opposing first and second peripheral wall portions, and opposing third and fourth peripheral wall portions extending between the first and second peripheral wall portions, each of the peripheral wall portions extending from the bottom portion at an obtuse angle with respect to a plane defined by the bottom portion and defining an interior area of the container;
an upper edge of the container defined by edges of the peripheral wall portions distal from the bottom portion;
the first and second peripheral wall portions comprising an inner flap defining an inner ledge extending into the interior area, the inner ledge located between the bottom portion and the upper edge of the container;
the first and second peripheral wall portions comprising a side wall panel, wherein the side wall panel defining an outer ledge located between the bottom portion and the upper edge of the container, the side wall panel hingedly joined to the bottom portion, the outer ledge is defined at an edge formed by a cut-out area on the side wall panel, the cut-out area being defined by a first cut-out edge extending from a longitudinal edge of the bottom portion, a second cut-out edge extending from and oriented generally perpendicular to the first cut-out edge and an open side defined by an imaginary line extending from a lateral edge of the bottom portion, the edge formed by the cut-out area facing toward the bottom portion; and
the inner ledges being positioned to engage outer ledges of a similarly-configured container whereby a spacing between a stack of nested containers is defined by the outer ledges of the similarly-configured container seated on the inner ledges of the container.

16. The container as set forth in claim 15 , wherein the inner flaps overlap the respective cut-out areas and form portions of an outer surface of the first and second peripheral wall portions at the cut-out areas, and the inner flaps fit within cut-out areas of the similarly-configured container when the similarly-configured container is nested within the container.

17. The container as set forth in claim 15 , wherein the inner flaps are hingedly attached to the bottom portion, and the one of a wall panel or a further flap of each of the first and second peripheral wall portions comprises a connection flap, the connection flaps of the first and second peripheral wall portions are hingedly attached to the third and fourth peripheral wall portions and overlap at least a portion of respective inner flaps, the outer ledges are defined by edges of the connection flaps that face toward the bottom portion.

18. The container as set forth in claim 15 , wherein the first and second peripheral wall portions comprise side walls of the container and the third and fourth peripheral wall portions comprise end walls of the container.
