## Title
Bakery tray

## Abstract

A tray includes a base and a plurality of walls extending upward from the base. In one feature, a first wall of the plurality of walls may include a projection outward from the first wall. The projection is aligned with an upper edge of the first wall, such that the projection is outward of a portion of the upper edge of the first wall. The projection of an identical upper tray stacked on the tray would interlock with the upper edge of the first wall to resist outward deflection of the upper edge of the first wall of the tray. In another feature, a platform may extend inward from at least one of the walls to support smaller trays stacked thereon. In another feature, an exterior of each of the side walls may include an interlocking recess for receiving automated handling equipment for supporting the tray.

## Background
This application is a divisional of U.S. Ser. No. 13/359,542, now U.S. Pat. No. 8,763,809, which claims priority to U.S. Provisional Application Ser. Nos. 61/437,326, filed Jan. 28, 2011, 61/480,180, filed Apr. 28, 2011 and 61/566,510, filed Dec. 2, 2011.


BACKGROUND
Bakery trays typically include a base from which front, rear and side walls extend upward. The side walls may include feet that are arranged relative to recesses at upper edges of the side walls such that the tray can stack with an identical tray at a first orientation and nest (or stack at a different height) with the identical tray at a second orientation, where the second orientation is 180° relative to the first orientation.
When many of these trays are stacked or nested, a substantial portion of the weight from each tray and the trays above it is transferred to the tray below via the feet. However, for the bottom tray on the floor, the feet may not contact the floor. Rather, the bottom tray is supported on drag rails, which are inward of the feet. Thus, the weight of all the trays above the bottom tray bears on the bottom tray at points outward of the drag rails, which may cause the side walls of the bottom tray to twist outward.
SUMMARY
A tray having one feature disclosed herein includes a base and a plurality of walls extending upward from the base. A first wall of the plurality of walls includes a projection outward from the first wall. The projection is aligned with an upper edge of the first wall, such that the projection is outward of a portion of the upper edge of the first wall. In this manner, the projection of an identical upper tray stacked on the tray would interlock with the upper edge of the first wall to resist outward deflection of the upper edge of the first wall of the tray.
In one embodiment disclosed herein, the projection has a T-shaped cross-section, complementary to a T-shaped recess in the upper edge of the first wall.
A tray having another feature disclosed herein includes a base and a plurality of walls extending upward from the base. A platform extends inwardly from at least one of the walls. The platform can be used to support smaller trays stacked thereon. For example, trays that are approximately half the size of the tray can be supported on three of the walls and the platform. In the embodiment disclosed herein as one example, platforms extend inwardly from an opposing pair of the walls to support the half-size trays.
In a tray having another feature disclosed herein, a base includes front and rear walls extending upward from front and rear edges of the base. Side walls extend upward from side edges of the base. Each of the side walls includes at least one interlocking recess for receiving automated handling equipment for supporting the tray.
In one specific example disclosed herein, each interlocking recess is defined by a curved upper wall protruding outwardly from the side wall.

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 generally includes a base 12, front and rear walls 14 extending upwardly from front and rear edges of the tray 10, and side walls 15, 16 extending upwardly from side edges of the base 12. The side walls 15, 16 include handles 18 formed therein. Each of the front and rear walls 14 includes a pair of handles 20 formed therein. Each of the front and rear walls 14 includes a platform 22 projecting inwardly adjacent an upper edge thereof and centered between the handles 20. The platform 22 is generally hollow with openings 58 to the exterior of the tray 10 between ribs 60.
Each of the side walls 15, 16 includes a pair of interlocking recesses 24 for interlocking with automated handling equipment. Each side walls 15, 16 further includes a rear foot 26, front foot 28, and center projection 30 projecting downwardly. The front foot 28 is adjacent the front edge of the tray 10 while the rear foot 26 is spaced away from the rear edge of the tray 10. An upper edge of each side wall 15, 16 includes a rear recess 32 aligned with the rear foot 26, a front recess 34 aligned with the front foot 28 and a center recess 36 aligned with the center projection 30. An inner rail 38 extends across portions of the side walls 15, 16. The front and rear walls 14 include a double-walled lip portion 40 that projects outwardly relative to a lower portion of the front and rear walls 14. The upper edge of the front and rear walls 14 each include a raised central portion 44 adjacent the platform, a recessed portion 42 between the raised central portion 44 and each side wall 15, 16, and an outer raised portion 45 adjacent each side wall 15, 16.
FIGS. 2A and 2B show the two sides of the tray 10. FIG. 2A shows the same side wall 16 as FIG. 1. FIG. 2B shows the opposite side wall 15. As shown in FIG. 2A, on side wall 16, the feet 26, 28 are spaced further outward (toward front and rear walls 14), while in FIG. 2B, on side wall 15, the feet 26, 28 are spaced further inward (away from front and rear walls 14). This is one way of providing stacking at a high stack position in one orientation and at a low stack position (or alternatively, nesting) in another (180 degree) orientation.
FIG. 3 is a front view of the tray 10.
FIG. 4 is a bottom perspective view of the tray 10. The base 12 includes a upper, planar panel portion 90 with a plurality of cross-ribs 92 projecting downward therefrom, including a peripheral rib 94 extending along most of the periphery of the front and rear walls 14. Each peripheral rib 94 includes a recessed portion 96, where the peripheral rib 94 juts inwardly to expose a portion 98 of the planar panel portion 90. The exposed portion 98 of the upper planar portion 90 is aligned with the platform 22 (FIG. 1). As a result, when one tray 10 is stacked on another tray 10, the platforms 22 of the lower tray 10 will be received within the recessed portions 96 of the peripheral ribs 94 of the upper tray 10 and the ribs 92, 94 will not impact the platforms 22 and prevent proper stacking of the trays 10. Drag rails 100 extend downward from the base 12 inward of each side wall 15, 16. The drag rails 100 may be double-walled drag rails 100 with cross-ribs, as shown. The bottom surface of the feet 26, 28 on the side wall 15 each include a central recess 27, while the feet 26, 28 on the side wall 16 each include a lateral recess 29, such that the lateral recesses 29 are open laterally facing one another.
FIG. 4 also shows the interlocking recesses 24. Each side wall 15, 16 includes a plurality of ribs 66 extending outwardly of a planar wall portion. Ribs 68 partially define the interlocking recess 24. The ribs 68 form an upper curved wall and two generally vertical walls. A plurality of vertical ribs 72 extend downward from the upper curved wall to increase the strength and rigidity of the upper curved wall and to provide more gripping with the automated handling equipment.
FIG. 5 is a top view of the tray 10.
FIGS. 6-7 show the tray 10 with a similar tray 10′ stacked thereon in a low stack position, i.e., in a similar orientation with the front feet 28′ received in the front recesses 34 and the rear feet 26′ received in the rear recesses 32. The center projections 30′ are received in the center recesses 36.
In FIGS. 8-9, the upper tray 10′ is rotated 180° and is stacked on the lower tray 10 in a high stack position, i.e., with the rear feet 26′ stacked on the upper edge of the side walls 16 and the front feet 28′ stacked on the upper edge of the side walls 16, not received in the recesses 32, 34. In the high stack position, larger goods or more layers of goods can be placed in the lower tray 10.
FIGS. 10-11 illustrate the upper tray 10′ as it is being slide-stacked onto the lower tray 10. Referring to FIG. 11, the upper edge of the front and rear walls 14 (front and rear walls 14 are symmetric about longitudinal and lateral axes in this embodiment) is shown in more detail. The upper edge of the front and rear walls 14 each includes the recessed portion 42 and an outer raised portion 45. A notch 102 is formed in the outer raised portion 45 to accommodate the drag rail 100′ of the upper tray 10′. The feet 26′ of the upper tray 10′ rest on the inner rail 38 of the lower tray 10 and an upper surface 105 of the side wall 16. A downward projection from the central projection 30′ of the upper tray 10′ extends into an outer notch 104 in the upper edge of the bottom tray 10. An outer rail 106 projects upwardly from the side wall 16 outward of the upper tray 10′.
As shown in FIG. 12, the tray 10 can support thereon and be supported on two prior art trays 110 that are approximately half the size of the tray 10. The prior art tray 110 includes a base 112, front and rear walls 114 and side walls 116. The prior art tray 110 is symmetric about the long axis, i.e. the side walls 116 are mirror images of one another. The front and rear walls 114 each include a plurality of vertical ribs 117 on an exterior surface thereof. The lower ends of the ribs 117 are aligned along an arc and therefore are not sufficient for stably supporting the prior art tray 110 on the front and rear walls 14 of the tray 10. Thus, the front and rear walls 114 of the prior art tray 110 are also supported on the platforms 22.
The prior art tray 110 includes rear support columns 118 having three castellations 120 on an upper support surface thereof. Front support columns 122 each have a single castellation 124 on an upper support surface thereof.
As shown in FIG. 13, the vertical ribs 117 of the prior art trays 110 align with the recessed portion 42 of the upper edge of the front and rear walls 14.
Referring to FIG. 14, the feet 26 of the tray 10 contact the upper surface of the rear support columns 118 rearward of the castellations 120. The feet 28 contact the upper surface of the front support columns 120 rearward of the castellation 124.
FIGS. 15-17 show the trays 10, 110 of FIG. 12 with one upper prior art tray 110 removed. FIG. 16 is an enlarged view of one of the platforms 22 (the other is identical) supporting the prior art tray 110. The platform 22 extends inwardly from an inner surface of each front and rear wall 14. The platform 22 includes a central support surface 46 spaced away from outer support surfaces 48. A ridge 50 projects upwardly from an inner edge of the central support surface 46. Ridges 52 project upwardly from inner edges of the outer support surfaces 48. Lower surfaces 54 are between each outer support surface 48 and the central support surface 46. A rib 113 extending downwardly from the base 112 of the prior art tray 110 is supported on the lower surface 54 of the platform 22.
FIG. 17 is a cutaway view through the platform 22 of FIG. 16. FIG. 18 is an enlarged view of the platform 22 of FIG. 17. The platform 22 is generally hollow with openings 58 to the exterior of the tray 10 adjacent ribs 60.
FIGS. 19-21 show a halved tray 10 (for purpose of illustration) stacked on the prior art tray 110. Referring to FIG. 20, the base 12 of the tray 10 can be viewed as an upper, planar panel portion 90 from which a plurality of cross-ribs 92 extend downward. The recessed portion 96 of the peripheral rib 94 is supported on the upper support surface of the front column portion 122 inward of the single castellation 124. Referring to FIG. 21, the cross-ribs 92 of the base 12, are supported on the rear column portion 118 between the castellations 120. FIG. 22 is a bottom perspective view of the cross-ribs 92 and peripheral rib 94, showing the arrangement to accommodate the castellations 120, 124 (FIGS. 20-21).
FIGS. 23-25 together illustrate the alignment of the prior art tray 110 on the side wall 16 of the tray 10. FIG. 23 shows the side wall 16. The rear foot 26 and front foot 28 are each outward of a window 128, which is outward of the interlocking recess 24. The rear recess 32 and front recess 34 are therefore also aligned outward of the windows 128.
Referring to FIG. 24, in one orientation, the rear foot 130 of the prior art tray 110 is supported on the side wall 16 outward of the recess 32, while the front foot 132 of the prior art tray is supported on the side wall 16 inward of the recess 34.
Referring to FIG. 25, in the other orientation, the rear foot 130 is supported outward of the recess 34, while the front foot 132 is supported inward of the recess 32.
FIGS. 26-29 illustrate the alignment of the prior art tray 110 on the side wall 15 of the tray 10. FIG. 26 shows the side wall 15. The rear foot 26 and front foot 28 are each inward of a window 128 and immediately adjacent the interlocking recess 24. The rear recess 32 and front recess 34 are therefore also aligned inward of the windows 128. FIG. 27 shows one orientation of the prior art tray 110, in which the rear foot 130 of the prior art tray 110 is supported on the side wall 16 outward of the recess 34, while the front foot 132 of the prior art tray is supported on the side wall 16 outward of the recess 32. Referring to FIG. 28, in the other orientation, the rear foot 130 is supported outward of the recess 32, while the front foot 132 is supported inward of the recess 34.
FIGS. 29 and 30 are upper perspective views of the side walls 116 of the prior art tray 110.

In FIG. 31, the front foot 28 is stacked on the side wall 116, while the rear foot 26 is stacked on the rear support column 118. One of the castellations 120 is received in the central recess 27 (FIG. 4) of the rear foot 26, adjacent the drag rail 100. On the other side wall 116, shown in FIG. 32, the rear foot 26 is stacked on the side wall 116, while the front foot 28 is stacked on the rear support column 118, with one of the castellations 120 received in the central recess 27 (FIG. 4) of the front foot 28, adjacent the drag rail 100.
FIGS. 33 and 34 show the side wall 16 of the tray 10 stacking on the side walls 116 of the prior art tray 110. In FIG. 33, the front foot 28 is stacked on the rear support column 118, with one of the castellations 120 received in the lateral recess 29 (FIG. 4) of the front foot 28, adjacent the drag rail 100. The rear foot 26 is stacked on the front support column 122. On the other side wall 116, shown in FIG. 34, the rear foot 26 is stacked on the rear support column 118, with one of the castellations 120 received in the lateral recess 29 (FIG. 4) of the rear foot 26, adjacent the drag rail 100. The front foot 28 is stacked on the front support column 122.
Automated handling equipment may include a lifting and pulling device, such as the device 80 shown in FIGS. 35-38. The device 80 includes a center bar 82 having hinge pins 84 projecting from each axial end. Arms 86 extend downward from the center bar 82. A projection 88 is formed at the outer end of each arm 86. As shown in FIGS. 37 and 38, the device 80 can be used to engage the interlocking recesses 24 in either end of the tray 10. The projection 88 at the end of each arm 86 provides some self-alignment between the device 80 and the tray 10. The device 80 can lift and pull the tray 10.
FIG. 39 is a perspective view of a bakery tray 210 according to a second embodiment. The bakery tray 210 is identical to the tray 20 of the first embodiment except as otherwise described below or as shown in the Figures. The bakery tray 210 generally includes a base 212, front and rear walls 214 extending upwardly from front and rear edges of the tray 210, and side walls 215, 216 extending upwardly from side edges of the base 212. The side walls 215, 216 include handles 218 formed therein. Each of the front and rear walls 214 includes a platform 222 projecting inwardly adjacent an upper edge thereof and centered between the handles 220.
Each of the side walls 215, 216 includes a pair of interlocking recesses 224 for interlocking with automated handling equipment. Each side walls 215, 216 further includes a rear foot 226, front foot 228, and center projection 230 projecting downwardly. Recesses in the upper edge of the side walls 215, 216 provide for different stacking heights; however, in this embodiment, the recesses for the high stacking position are positioned directly above the feet 226, 228 so that load can transfer directly from foot to foot in the high stacking position (in the low stacking position, there are many other contact areas between the upper tray and the lower tray in addition to the feet in the low-stacking recesses).
An upper edge of each side wall 215, 216 includes a center recess 236 above the handles 218 and aligned with the center projection 230.
The center recess 236 is shown more clearly in FIG. 40. The center recess 236 is T-shaped including a large portion 237 and a narrow portion 239, as defined by two wall portions 241.
The center projection 230 is shown in more detail in FIG. 41. The center projection 230 is also T-shaped, having a single-wall thickness base rib 273 extending outward from the side wall 216 (the projection side wall 215 can be identical) to outer cross portion 274 generally parallel to the side wall 216. Outer cross portion 274 includes a pair of vertical ribs 275 each having a tapered, narrow portion 276 above their bottom edges and above the bottom edge of the outer cross portion 274. The narrow portions 276 are preferably curved, concave portions. A bottom horizontal rib 277 extends across the bottom of the vertical ribs 275 defining the bottom of the cross portion 274.
A bottom view of the tray 210 is shown in FIG. 42, where the center projection 230 is also shown.
In FIG. 43, the tray 210 is shown with an identical tray 210 stacked thereon in the high stack position. The center projection 230 of the upper tray 210 is partially received in the center recess 236 of the lower tray 210. The interlocking T-shapes of the center projection 230 and center recess 236 prevent the side walls 215, 216 of the lower tray 210 from bowing outward under the weight of the tray 210 and numerous other trays 210 stacked in turn thereon, which may each be loaded with goods. As shown in FIG. 44, the base rib 273 of the center projection 230 is received between the wall portions 241 of the center recess 236, thereby capturing the cross portion 274 of the center projection 230 of the upper tray 210, thereby preventing the side wall of the lower tray 210 from bowing outward.
In FIGS. 45 and 46, the trays 210 are in the low stacked position. The center projection 230 of the upper tray 210 is received fully within the center recess 236 of the lower tray 210.
If the upper tray 210 is lifted at the opposite side, as shown in FIGS. 47 and 48, this pivots the center projection 230 within the center recess 236. The narrow portions 276 of the vertical ribs 275 accommodate and receive the front edge of the side wall as the upper tray 210 is pivoted. Thus, the center projection 230 reinforces the side wall of the lower tray 210 during stacking, but also permits the upper tray 210 to pivot when stacked.
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.
