BACKGROUND
Nestable containers or trays with pivotable support arms are well known. Generally, the trays are nestable within one another when empty for efficient storage and shipping. A pair of supports or bails can be pivoted to a position over the floor of the tray so that a similar tray can be supported thereon. In this manner trays can be stacked when there are goods stored in the trays.
Some trays having supports that are movable to more than one height, so that the trays can be stacked more efficiently when they are only partially full. In some of these multi-height trays, the supports are only supported on a single thickness wall, which may not be sufficient under a stack of fully-loaded trays. This is particularly true for multi-height trays where the supporting portion of the wall is undercut or cantilevered somewhat to provide a lower supporting portion vertically aligned with the upper supporting portion.
SUMMARY
A nestable container includes a base wall and a pair of side walls and a pair of end walls extending upward from the base wall. The walls are nestable within side walls and end walls of an identical container.
The container includes one or more supports, each having a pair of support arms extending from a support bar. The support is movable between a nesting position where the support bar is outward of the base wall to permit nesting, a high stack position where the support bar is a first height over the base wall to permit stacking, and a low stack position where the support bar is a second height over the base wall to permit stacking. The support bar is not directly supported on the side walls when the support is in the high stack position.
The support bar is supported on the side walls at a point spaced away from the support bar. This permits the support bar to be supported at multiple heights without an undercut under a support surface on the side wall, but with the support bar still being received in an elongated recess on the underside of the base at both positions.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
A nestable container 10 according to one embodiment is shown in FIG. 1. The container 10 generally includes a base wall 12, opposed side walls 14 and opposed end walls 16. A support 18 (or bail) is pivotably and slidably mounted to the side walls 14 adjacent each end wall 16. The side walls 14 and end walls 16 each include an upper wall portion 20 and a lower wall portion 22. The upper wall portions 20 of the side walls 14 each include an outer wall portion 24 and an inner wall portion 26, spaced inwardly from the outer wall portion 24. The outer wall portion 24 is spaced outwardly of the lower wall portion 22 to form a lip along the periphery of the container 10.
An upper support surface 40 is formed in the inner wall portion 22 adjacent each end wall 16. A lower support surface 42 is formed between each upper support surface 40 and the closest end wall 16. Unlike many prior art designs, the upper support surface 40 is not cantilevered over the lower support surface 42. This improves the strength of the portion of the wall near the upper support surface 40.
The support 18 is pivotable and slidable among a plurality of positions, including the home/nest position shown in FIG. 1. As shown in FIG. 12, in the home/nest position, an identical container 10′ can be nested fully in the container 10 (i.e. the lower wall portion of the upper container is fully or nearly fully received within the side walls 14 and end walls 16 of the lower container 10).
The support 18 is shown in more detail in FIGS. 2-4. As shown, the support 18 includes a support bar 26 connected at each end to one end of a support arm 28. The opposite end of each support arm 28 includes a pivot pin 30 protruding outwardly and a projecting portion 32 projecting laterally relative to the support arm 28 and the support bar 26. An offset bar 36 projects inwardly from the end of each projecting portion generally parallel to the support bar 26. A second arm 34 extends from the support bar 26 to the inner end of the offset bar 36.
As shown in FIG. 5, each pivot pin 30 is slidably and pivotably received in a wide V-shaped opening 48 in the outer wall portion 24. In FIG. 5, the support 18 is shown in the nest or “home” position. In the home position, the support bar 26 is received on lower outer support surfaces 44 and the offset bars 36 on upper outer support surfaces 46. In this position, the hinge pins 30 are slid to an innermost position in the opening 48.
In FIGS. 6 and 7, the support 18 is pivoted and slid to a high stack position. Referring to FIG. 7, the offset bars 36 and projecting portions 32 are received on the upper support surfaces 40 and the pivot pins 30 are slid to a mid/low-point of the V-shaped opening 48. As shown in FIG. 7, when an identical container 10′ is stacked on the support bars 26 of the container 10, the support bar 26 is received in a lower channel 50′ in an underside of the base 12′, generally toward an interior side of the channel 50. In this position, the base 12′ of the upper container 10′ is at a maximum distance from the base 12 of the lower container 10, thus providing the most volume for goods within the container 10. The weight of the upper container 10′ and its contents is distributed by the support 18 to both the upper support surfaces 40 and the bottom edge of the V-shaped opening 48.
In FIGS. 8 and 9, the supports 18 are moved to a low stack position. Referring to FIG. 9, the offset bars 36 are supported on the lower support surfaces 42, while the pivot pins 30 are supported by the lower edges of the V-shaped openings 48 in the outer wall portions 24. Again, the support bar 26 is received in the channel 50′ of the upper container 10′, although toward an exterior edge of the channel 50′. The weight of the upper container 10′ and its contents is distributed to both the lower support surface 42 and the lower edge of the V-shaped opening 48. In the low stack position, the volume for storage in the lower container 10 is reduced, so that smaller items can be shipped or stored in containers 10 efficiently.
FIGS. 10 and 11 show the supports 18 pivoted and slid to a high nest position in which the offset bars 36 project upward above an uppermost edge of the side walls 14 and end walls 16. The offset bars 36 are generally vertically aligned outward of the lower wall portions 22 of the end walls 16. Referring to FIG. 11, in the high nest position, the support bars 26 are received in the upper outer support surfaces 46 and the pivot pins 30 are supported on the lower edge of the V-shaped openings 48. Most of the weight of the upper container 10′ and its contents is transferred directly through the offset bars 36, the projecting portions 32 and the support bars 26 to the end walls 16 of the lower container 10. In the high nest position, the lower wall portion 22′ of the upper container 10′ is received substantially but not entirely within the side walls 14 and end walls 16. The offset bars 36 support the upper container 10′ below the peripheral lip portion of the end walls 16′ of the upper container 10′. In this position, the base wall 12′ of the upper container 10′ is spaced above the base wall 12 of the lower container 10 by a distance less than in the high stack or low stack positions, but more than in the nest/home position. Thus, small items can be efficiently shipped and stored in a plurality of containers 10 arranged in such a manner.
In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
