The present invention relates to a stackable low depth tray for storing and transporting beverages containers, such as bottles.
Plastic bottles are widely used as containers for soft drinks and other beverages. These bottles are often stored and transported in trays, particularly plastic trays having side walls, end walls and dividers defining pockets between the side walls and end walls. There are many known tray designs that are referred to as “low depth” trays in which the side walls, end walls and dividers are lower than the height of the stored bottles, and in which the bottles support the weight of additional trays and bottles stacked thereon.
One known type of low-depth tray had sidewalls and dividers all at the same height. In later versions of this tray, a portion of the dividers was lowered to reduce weight. This height of the side walls and dividers was the nest stop for empty crates stacked thereon in both a column (i.e. trays aligned) and cross stack (i.e. each row of trays is ninety degrees relative to the row of trays below it, or the trays are longitudinally aligned and longitudinally offset by 50%).
In the known trays, the bottom ribs of the tray base extend down approximately 0.1″ further than the sidewall. Raising the bottom edge of the sidewalls in this manner makes it easier for a delivery person to get a hand truck blade under a stack of crates to move them. As a result, the sidewalls of stacked empty crates do not rest on each other. It is the bottom ribs extending down from the base that rest on top of the dividers when stacked. One problem with this raised side wall design is that empty stacks are not as stable because the footprint is much smaller stacking on dividers only.
Later generation trays improved on this design by adding ribs on the outside of the walls to capture the sidewall of the crate above and also widening the lower part of the castle to capture the bottom ribs of the crate above.
In another tray, the side walls between the columns and the dividers are lowered for more visibility. As a result, the side walls do stack on the top of the side walls of the tray below. In this design, the columns are taller in order to better support bottles with a portion of reduced diameter between the base and a mid-portion of the bottle. One problem with this design is that the taller columns extend into the handle area of the tray above, in both a column stack and a cross stack position. In order to accommodate the handle, the columns are aggressively tapered on the outside face of the columns on the perimeter of the tray. However, the center columns still do not accommodate the handle in a longitudinal cross-stack arrangement. Also, this design results in corner columns that are more fragile because they include the aggressive taper on two sides.
A tray for storing and transporting bottles according to one embodiment of the present invention includes a base and a plurality of interior columns extending upwardly from the base, including a center interior column. A plurality of side columns extend upwardly along sides of the tray, including two noncenter side columns and a center side column on each side of the tray, each center side column between the two noncenter side columns. Corner columns are at corners of the tray. The center side columns and the corner columns have outer ledges defining a nesting height of the tray, such that the side walls of a similar tray nested thereon would contact and rest on the outer ledges of the center side columns and the corner columns. The noncenter side columns do not include an outer ledge at the nesting height.
According to another, independent feature of the present invention, exterior surfaces of opposing noncenter side columns on opposite sides of the tray are spaced from one another by a distance less than that by which exterior surfaces at the first height of opposing center side columns on opposite sides of the tray. In other words, the noncenter side columns are offset inwardly relative to adjacent columns. This accommodates the handle of a tray stacked thereon in a ninety-degree cross-stacked configuration.
According to another, independent feature of the present invention, exterior surfaces of the end columns are offset inwardly relative to the respective adjacent corner columns. This accommodates the handle of a tray nested thereon in a column stack configuration.
According to another, independent feature of the present invention, the center interior column and the center side columns include spaced apart halves, defining a passage therethrough. The halves of the center interior column are spaced further apart than the halves of the center side columns in order to accommodate the handle cross-stacked longitudinally thereon.
These and other features of the application can be best understood from the following specification and drawings, the following of which is a brief description.
A tray 10 according to one embodiment of the present invention is shown in
The lateral dividers 14b each connect one of the interior columns 20 with one of a plurality of side columns 22a, 22b positioned along a side edge of the tray 10. The side columns 22a, 22b (collectively “side columns 22”) center side columns 22a and noncenter side columns 22b. The tray 10 further includes four corner columns 24 extending upwardly from the corners of the tray 10. End columns 26 extend upwardly from ends of the tray 10, between the corner columns 24.
Side walls 28 on each side of the tray 10 define outer ledges 30a, 30b adjacent the center side columns 22a and noncenter side columns 22b, respectively. The side walls 28 further define outer ledges 32 adjacent the corner columns 24. Exterior surfaces 34b of the noncenter side columns 22b adjacent the outer ledges 30b are offset inwardly relative to the exterior surfaces 34a of the center side columns 22a adjacent the outer ledges 30a and relative to the exterior surfaces 36 of the corner columns 24 adjacent the outer ledges 32. The outer ledges 30a of the center side columns 22a and the outer ledges 32 of the corner columns 24 define the nesting height, and the outer ledges 30b of the noncenter side columns 22b are slightly lower than the nesting height. Alternatively, the outer ledges 30b of the noncenter side columns 22b could be eliminated.
At the ends of the tray 10, an end wall 46 defines outer ledges 42 at the nesting height adjacent exterior surfaces 44 of the corner columns 24. The end wall 46 also defines an outer ledge 48 below the nesting height adjacent an exterior surface 51 of the end column 26. The exterior surface 51 of the end column 26 is offset inwardly relative the exterior surfaces 44 of the corner columns 24. A handle 49 is defined by a downwardly open recess formed in the end wall 46 below the end column 26.
The center side columns 22a are split to define a lateral passage 50 therethrough, which is aligned with a lateral passage 52 through the center interior column 20a. As shown in
As a result, only the outer ledges 30a and lower surface 60 of the lateral passage 50 of the center side columns 22a and the outer ledges 32, 42 of the corner columns 24 are at the nesting height. Considering the tray 10 as two sets of 2×2 pockets, this creates nesting stops only at the four corners of each of the sets of four pockets. This provides stable, consistent nesting in a column stack and in cross-stack (longitudinal or lateral).
Further, within each set of 2×2 pockets, if one considers the split center interior column 20a and the center side columns 22a as two separate columns each, then the non-corner columns along the perimeter of each 2×2 set (i.e. end column 26, noncenter side columns 22b, and one half of the center interior column 20a) are each offset inwardly relative to its adjacent “corner columns” (now also considering the split center side columns 22a as “corners” within each 2×2 set). The offset end column 26 provides clearance for the handle 49 of a similar tray column stacked thereon. The offset noncenter side columns 22b provide clearance for the handle 49 of a similar tray cross-stacked laterally (i.e. 90 degrees) thereon. The offset halves of the center interior column 20a provide clearance for the handle 49 of a longitudinally cross-stacked similar tray.
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.
