DETAILED DESCRIPTION

[0021] While this invention is susceptible of embodiments in many different forms, there is shown in the drawings, and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.

[0022] As illustrated in FIG. 1, the present invention is directed to a tray system 10 comprising a plurality of trays 12 configured to support a plurality of bottles 14. The plurality of trays 12 interact with a plurality of support sleeves 16. The trays 12 and support sleeves 16 allow for stacking a plurality of layers of bottles 14 on a pallet 18 (or dolly or other support structure). FIG. 1 shows four layers of bottles 14 supported on the pallet 18. One tray 12 is placed on the top of the layers of bottles 16 to act as a top cap for the system 10. However, other top caps can be utilized.

[0023] FIG. 2 shows a collapsed system 10 without the bottles 14. The trays 12 are supported on the pallet 18. The sleeves 16 can be collapsed or folded and placed on top of the trays 12 and pallet 18. In this manner, the system can be easily shipped back after transporting bottles to a destination. The reduced volume of the collapsed system 10 provides for cost effective and efficient shipping.

[0024] As shown in FIG. 3, the trays 12 are generally rectangular and include a first side 20, a second side 22, first end 24 and a second end 26. Each of the sides 20, 22 and ends 24, 26 is a generally rectangular shaped panel. The tray 12 includes a plurality of ribs 28 that extend between the first and second sides 20, 22 and the first second ends 24, 26 to form an upper support surface for the bottles 14. Certain of the ribs can extend upward higher than others to form separate bottle pockets 30 or areas on the upper surface. The upper surface of the tray 12 can also include a channel 32 (again by varying the height of certain ribs) or other support structure along a perimeter to support a sleeve 16 on the upper surface of the tray 12. The sleeve 16 can then be used to support another like tray 12 above the tray 12 at issue. In this manner, the trays 12 and sleeves 16 can be stacked to form a plurality of layers as shown in FIG. 1.

[0025] The lower surface of each tray 12 can also include a channel 34 or other structure to enable an upper tray to rest on and be supported by an upper edge of a lower sleeve 16. The upper and lower channels 34, 32 help keep the sleeves in the proper locations along the perimeter of the tray 12. As illustrated in FIG. 5, the sleeves 16 can be sized so that bottles 14 on a lower tray 12 do not contact or otherwise support an upper tray 12. This keeps pressure (from the weight of upper layers) off of the bottles 14.

[0026] FIG. 4 shows a single layer of bottles 14 supported on the tray 12 of FIG. 3. The bottles 14 can be one gallon bottles (such as plastic milk bottles), however, other sizes and shapes can be used. A sleeve 16 is shown around the bottles 14 along the periphery of the tray 12. The sleeve 16 includes four side panels 36. Each side panel 36 of a sleeve 16 shown in FIG. 4 includes a window 38 for visual inspection of the bottles 14 on the tray 12 (however, the sleeve 16 can include more than one window 38 per panel 36, or have no windows 36 on one or more of the panels 36). The window 38 is important when other layers of trays 12 are stacked on top of the tray 12, which limit inspection from the top of the tray 12.

[0027] Each sleeve 16 can be of one-piece construction. That is, the sleeve 16 can be formed from a single blank of material having four panels 26. The two ends of the blank can be connected to form a rectangular opening or shape for placement of the sleeve 16 in the channel 32 of the tray 12. The sleeve 16 can be folded (e.g., bringing two opposing corners together) to collapse the sleeve 16 when not being used. In use, the sleeve 16 is opened and positioned along the perimeter of a first or lower tray to support one or more upper trays (or a top cap for the uppermost tray/sleeve combination).

[0028] The plurality of stacked trays 12 and sleeves 16 can be supported on a pallet 18, dolly or other like structure for transport. When empty, the trays 12 can be stacked on the pallet 18 or dolly, and the sleeves 16 can be collapsed and placed thereon for return.

[0029] FIG. 5 shows a cross-sectional view of a stack of trays 12 holding bottles 14. As is evident in the top tray 12 certain of the ribs 40 extend upward higher than others 42 to form the pockets 30 for each bottle 14. Similarly, ribs 44 along the perimeter are small than other ribs to form the channels 32, 34. While the channels 32, 34 can extend uninterrupted around the perimeter, some of the ribs crossing the channels 32, 34 can extend upward higher than the channel rib 44. The sleeve 16 can be provided with slots to accommodate such cross-ribs. The slots can then be used to align the sleeve on the tray 12 (this can be useful for proper placement of the sleeve if it is in two or more parts that do not extend to the corners).

[0030] Preferably, the trays are formed from a molded plastic or other suitable material. The sleeve is preferably plastic, such as a corrugated plastic, or other suitable material (such as a paperboard or corrugated paper).

[0031] Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
