DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0031] A crate 10 according to one embodiment of the present invention is shown in Figure 1. The crate 10 includes a base 12, a pair of opposed side walls 14 and a pair of opposed end walls 16. The side walls 14 and end walls 16 are collapsible onto the base 12. The end walls 16 may include handles 18. Latches 20 selectively connect the side walls 14 to the end walls 16 to maintain the walls in the upright, use position.

[0032] The base 12 includes an upper panel 22 having a plurality of openings or vents 24 formed therein.

[0033] Referring to Figures 1 and 2, the side walls 14 each include a lower panel portion 26 on an inner surface of the side wall 14, an outer panel portion 28 at an outer surface of the side wall 14 and above the lower panel portion 26, and an upper panel portion 30 at an inner surface of the side wall 14 and above the outer panel portion 28. A plurality of ribs 32 extend outward from the lower panel portion 26 and upper panel portion 30 and inward from the outer panel portion 28.

[0034] Vertically-oriented vents 27 are formed in the lower panel portion 26.
Horizontally-oriented vents 29 are formed in the outer panel portion 28.
Horizontally-oriented vents 31 are formed in the upper panel portion 30. Horizontally-oriented lower vents 34 are formed in the lower panel portion 26 below the vertically-oriented vents 27.

[0035] The base 12 includes a plurality of spaced-apart upstanding side portions 40 defining lower openings 38. The side wall 14 is pivotably connected to the upstanding side portions 40.

[0036] Referring to Figures 1 and 3, the end walls 16 each include a lower panel portion 46 on an inner surface of the end wall 16, an outer panel portion 48 at an outer surface of the end wall 16 and above the lower panel portion 46, and an upper panel portion 50 at an inner surface of the end wall 16 and above the outer panel portion 48. A plurality of ribs 52 extend outward from the lower panel portion 46 and upper panel portion 50 and inward from the outer panel portion 48.

[0037] Vertically-oriented vents 47 are formed in the lower panel portion 46.
Horizontally-oriented vents 49 are formed in the outer panel portion 48.
Horizontally-oriented vents 51 are formed in the upper panel portion 50.

[0038] Figure 4 is a top view of the crate 10. The base 12 includes a plurality of vents 24. The vents 24 include a plurality of rows of vents 56 in which the rows extend parallel to the side walls 14 (in this example, there are six rows of vents 56). The vents 56 are elongated in a direction parallel to the end walls 16. The vents 24 further include a plurality of columns of vents 58, wherein the columns extend parallel to the end walls 16 (in this example, there are six columns of vents 58) and the vents 58 are elongated generally parallel to the side walls 14. The vents 24 further include three columns of offset vents 62 (the vents 62 elongated in a direction generally parallel to the side walls 14) between the first and second columns of vents 58, the third and fourth columns of vents 58 and fifth and sixth columns of vents 58.
Vents 60 are formed between the second and third columns of vents 58 and fourth and fifth columns of vents 58. The arrangement of vents can also be viewed as a 3x3 array of container support surfaces, each having a rectangular perimeter of elongated vents that are oriented perpendicular to the perimeter. Figure 5 is a bottom view of the crate 10.

[00391 The spacing and arrangement of the vents 24 in the base 12 is further explained with reference to clamshell containers 100 shown in Figures 6-10. The clamshell container 100 is a known plastic container often used for shipping and selling fruit, such as strawberries, or other items that require refrigeration. The clamshell container 100 includes an upper portion 102 and a lower portion 104. The upper portion 102 includes a rim portion 106 extending around a periphery of a lid portion 108. A plurality of upper ventilation openings 110 are formed through tapered side walls and an upper wall of the lid portion 108. The lower portion 104 includes a rim portion 112 extending around a periphery of a base 114. A plurality of lower ventilation openings 116 are formed through tapered side walls and a lower wall of the base 114. A
plurality of connectors 118 connect the rim portion 106 of the upper portion 102 to the rim portion 112 of the lower portion 104. The connectors 118 also space the upper portion 102 from the lower portion 104 to provide additional ventilation.

[00401 As shown in Figure 11, a plurality of clamshell containers 100 can be placed in the crate 10 (in this example, nine). Figure 12 is a side view of the crate 10 and containers 100 of Figure 11. Figure 13 is a wireframe view of Figure 12. Referring to Figures 12 and 13, the lower ventilation openings 116 of the containers 100 align with the lower openings 38 and lower vents 34 of the crate 10. The vents 29 in the outer panel portion 28 of the crate 10 align with the gap between the upper portion 102 and the lower portion 104 of the container 100. The vents 31 in the upper panel portion 30 of the crate 10 align with the upper ventilation openings 110 of the containers 100.

[0041] Figure 14 is an end view of the crate 10 and containers 100 of Figure 11. Figure 15 is a wireframe view of Figure 14. Referring to Figures 14 and 15, the vents 49 in the outer panel portion 48 of the crate 10 align with the gap between the upper portion 102 and the lower portion 104 of the container 100. The vents 51 in the upper panel portion 50 of the crate 10 align with the upper ventilation openings 110 of the containers 100.

[0042] Figure 16 is a top view of the crate 10 and containers 100 of Figure 11. Figure 17 is a bottom wireframe view of the crate 10 and containers 100 of Figure 16.
The lower ventilation openings 116 along the long wall of the container 100 align with the rows of vents 56.
The lower ventilation openings 116 along the short wall of the container 100 align with the columns of vents 58. Some of the vents 58 align between containers 100, as do some of the offset vents 62 and vents 60. Each of the containers 100 is received on a container support surface defined by the perimeter of elongated vents, such that the elongated lower ventilation openings 116 of the container 100 are aligned with the elongated vents along the perimeter of each container support surface.

[0043] The alignment of vents on the crate 10 and containers 100 provides improved flow of cold air into the containers 100 when the crate 10 and containers 100 are placed in refrigeration.

[00441 The crate 10 can stack on an identical crate 10 either in an aligned orientation (not shown) or in a cross-stacked orientation, as shown in Figure 18 (as part of a cross-stacked stack of crates 10, in a known arrangement). As shown, the upper crate 10 is rotated ninety degrees relative to the lower crate 10, so that two thirds of the crates 10 overlap (if the crate's 10 width is two-thirds of its length). Figure 19 is a bottom view of the crates 10 of Figure 18. As shown, in the cross-stacked orientation, the vents 56 of the upper crate 10 align with the vents 58 of the lower tray 10, and vice versa. The offset vents 62 also align with vents 56.
This would also mean that the vents in the base 12 of the upper crate 10 are aligned with the upper ventilation openings 110 of the containers 100 (just as the vents in the base 12 aligned with the lower ventilation openings 116 of the containers 100, because the upper ventilation openings 110 are aligned with the lower ventilation openings 116).

[00451 Figure 21 shows the crates 10 and containers 100 aligned with the end wall 16 of one crate 110 adjacent one edge of a side wall 14 of the other crate 10. This is part of a lower layer of crates 10, where another layer would be stacked thereon, as in Figures 18 and 19. As shown in Figure 24, the vents 29, 49 align, the vents 31, 51 align and the vents 27, 47 align.

[00461 The crate 10 is thus designed to provide good ventilation when cross stacked with identical crates. Also, the crate 10 and the containers 100 in combination provide improved ventilation. This permits more rapid, even cooling of the produce (e.g.
strawberries) in the containers 100.

[00471 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.
