Bakery tray

Abstract

A tray includes a base and a pair of side walls extending upward from side edges of the base. Front and rear walls extend upward from front and rear edges of the base. The front and rear walls are shorter than the side walls. A plurality of support posts project upwardly from the upper edge of the front and rear walls. A lip is spaced outward of the front wall and the rear wall. Each lip includes a lower edge protruding downward to form columns aligned below the support posts. When stacked on a similar tray the columns contact the support posts of the similar tray to help support the front and rear walls. The base includes a recess below the columns for receiving the blade of a hand truck, which will transfer load throughout a stack of trays from columns to support posts.

Description

BACKGROUND

Plastic bakery trays include a base and side walls extending upward from side edges of the base. Front and rear walls are often shorter than the side walls to provide access to the baked goods (or other items) in the trays when they are loaded and stacked.

When loaded and stacked, the trays are supported on one another on the side walls, with the base and front and rear walls suspended from one side wall to the other. If a stack of loaded trays are moved by means of a hand truck, the blade of the hand truck may be inserted under the base, in the center of the front or rear walls. This may cause the center of the trays to deflect upward.

SUMMARY

A tray includes a base and a pair of side walls extending upward from side edges of the base. Front and rear walls extend upward from front and rear edges of the base. The front and rear walls are shorter than the side walls.

A plurality of support posts project upwardly from the upper edge of the front and rear walls. A lip is spaced outward of the front wall and the rear wall. Each lip includes a lower edge protruding downward to form columns aligned below the support posts.

When stacked on a similar tray the columns contact the support posts of the similar tray to help support the front and rear walls. The base includes a recess below the columns for receiving the blade of a hand truck, which will transfer load throughout a stack of trays from columns to support posts. The columns and support posts reduce the deflection of the trays when lifted by a hand truck.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A bakery tray 10 according to one embodiment of the present invention is shown in FIG. 1. The bakery tray 10 includes a base 12, which may be a grid or lattice of interconnected ribs, front and rear walls 14 and side walls 16. The front and rear walls 14 each include an upper edge which is lower than that of the side walls 16. Side flanges 18 extend inwardly onto the front and rear walls 14 from the side walls 16.

The front and rear walls 14 each include a lip 20 projecting outward and then downward from an upper edge of the front wall 14 and rear wall 14. The lip 20 may be connected to the front wall 14 and rear wall 14 at the upper edge of the front wall 14 and rear wall 14 and/or by vertical ribs connecting the lips 20 to the front wall 14 and rear wall 14. At two points spaced just inward of the side flanges 18 the lip 20 extends downward to form columns 22. Above each of the columns 22, a pair of support posts 24 project upward from the upper edge of the front and rear walls 14. In the example shown, each of the support posts includes a portion supported by and contiguous with the lip and a portion supported by and contiguous the front wall, with a transverse rib connecting the two portions.

A channel 28 is formed on the upper edge of each of the side walls 16. Feet 30 project downward from the side walls 16. The feet 30 are aligned with the channels 28.

FIG. 2 is a front view of the tray 10. Again, the lip 20 projects downward to form two columns 22. There are two support posts 24 projecting upward from the front wall 14 above each of the columns 22. The support posts 24 are spaced inward from the side flanges 18. The base 12 includes a recess 34 centered on the front and rear walls 14 and extending outward just outward of the columns 22. The base 12 also includes a chamfer 32 just inward of the columns 22.

FIG. 3 is a side view of the tray 10. The feet 30 project downward from the side walls 16.

FIG. 4 shows the tray 10 with an identical tray 10 stacked thereon. As is known, the feet 30 of the upper tray 10 are received in the channels 28 of the lower tray 10. On the front and rear walls 14, the support posts 24 of the lower tray 10 are aligned with the columns 22 of the upper tray 10. The support posts 24 either contact or nearly contact the columns 22 (in which case they would contact the columns 22 under load or if deflected by a hand truck).

FIG. 5 is a front view of the trays 10 of FIG. 4. As shown, the blade 50 of a hand truck can be received in the recess 34 in the base 12 of the lower tray 10. The width of the blade 50 aligns with the columns 22 and the support posts 24.

When a stack of loaded trays 10 is lifted by a hand truck with the blade 50 entering one of the front and rear walls 14, the weight of the trays 10 is primarily transferred from the upper trays 10 to the lower trays 10 via the side walls 16, which are outward of the blade 50. This causes the trays 10 to bend until the support posts 24 contact the columns 22. The support posts 24 and columns 22 reduce the cantilever section from the contact point of the blade 50 to the transfer of load in the stack of the trays 10. This reduces the amount of flexing by the trays 10, thereby protecting the product in the trays 10 and increasing the life of the trays 10.

FIG. 6 is a side view of the stacked trays 10.

When empty, the trays 10 can be cross-stacked as shown in FIG. 7. Cross-stacking the empty trays 10 reduces their height and volume for more efficient transportation and storage. As is known, when cross-stacked, the front and rear walls 14 of the upper tray 10 extend perpendicularly to, and are supported in contact on, the front and rear walls 14 of the lower tray 10 between the side flanges 18. The support posts 24 of the lower tray 10 project through the lattice openings in the base 12 of the upper tray 10.

Each example tray 10 is injection molded as a single piece of suitable plastic, such as HDPE.

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.
