DETAILED DESCRIPTION

(17) FIG. 5 illustrates a top down view 500 of an example plate 502, and FIG. 6 illustrates a cross-sectional view 600 of the plate 502 along line A-A of FIG. 5.

(18) The plate 502 comprises Styrofoam, plastic, paper pulp, cardboard, and/or other known material. The plate 502 is configured to support at least food and can be used outdoors (e.g., for picnics, barbeques, parties, etc.) and/or indoors. In either of these instances, the plate 502 is susceptible to receive wind. For example, at an outdoor picnic, the plate 502 is susceptible to receive wind whether resting on a table, the ground, a chair, a person's lap, etc. In another example, the plate 502 may be susceptible to receive wind from an open window, a fan, a breeze created from someone walking by, etc.

(19) The illustrated plate 502 is circular. In another embodiment, the plate 502 is elliptical, square, rectangular, irregular and/or other shape. The plate 502 includes a generally planar surface 506 with a radius 508 and a perimeter 509. In another embodiment, the surface 506 is concave, convex, sloped, irregular, etc. Furthermore, the illustrated planar surface 506 is configured as a single compartment. In another embodiment, the planar surface 506 is divided up into two or more compartments, e.g., separated by ridges, walls, protrusions, etc. The planar surface 506 has a first or top side 510 which is configured to support a food product, etc., and a second or bottom side 512 which is configured to rest on the surface 602. The first and second sides 510 and 512 are on opposite sides of the plate 502.

(20) The plate 502 further includes a rim or lip 514. The lip 514 includes a first linear section (or mid-region, wall, etc.) 516 with a length 518 and protruding up and outward from the first side 510 of the planar surface 506 in a direction away from the planar surface 506. The first linear section 516 surrounds the planar surface 506. The lip 514 further includes a second linear section 520 (or end-region, wall, etc.) with a length 522 and extending from the first section 516. The second section 520 slopes downward and away from the planar surface 506. The second section 520 surrounds the first linear section 516. The first and second linear sections 516 and 520 are symmetric about a line 524 bisecting an intersection 526 of the first and second linear sections 516 and 520, forming a carrot or inverse v shape (A) with an apex 530.

(21) A leading outer edge 528 of the second linear section 520 is in the plane of (co-planar with) the opposing side 512 of the planar surface 506 and rests on a surface 602 along with the opposing side 512 of the planar surface 506. With this configuration, generally, there is little to no gap between the leading outer edge 528 and the surface 602. This reduces or mitigates wind from entering under the lip 514 and exerting forces therein and creating pressures therein. In a variation, the leading outer edge 528 of the second linear section 520 is not in the plane of the opposing side 512 of the planar surface 506, but in a different plane, and either rests on the surface 602 (e.g., 522>518) or does not rest on the surface 602 (e.g., 522<518).

(22) FIG. 7 illustrates a cross-sectional view 700 of the plate 502 along a line B-B of FIG. 6 in connection with wind 702. In this example, the wind 702 is laminar flowing wind that flows towards the plate 502. In FIG. 8, a first component 802 of the wind 702 strikes the second linear section 520 on the upward linear slope, exerting a force (F1), which has both a horizontal component (F1.sub.h) and a downward vertical component (F1.sub.v). Wind traversing the apex 530 results in turbulent flow 804. The turbulent flow 804 breaks or disrupts the upward vertical lift force created by laminar flow over the apex 530.

(23) With this embodiment, the configuration of the lip 514 described herein reduces overall upward vertical lift forces. For example, the carrot shaped apex 530 reduces the upward vertical lift force above the lip 514, e.g., it breaks smooth laminar flow to minimize wind induced lift from air travelling over the top. This allows the plate 502 to maintain its location on the surface 602 and not lift from the surface 602 under wind conditions which would otherwise lift a plate, such as the plate 102, which did not produce the turbulent flow 804 to reduce the upward vertical lift force above the lip 514. In addition, the leading edge 528 touching the surface 602 further reduces upward vertical forces (F4.sub.v) 806 under the lip 514 due to pressure build up.

(24) FIG. 9 illustrates a variation of the plate 502 in FIG. 8 in which the first and second linear sections 516 and 520 are first and second concave sections 902 and 904. Similar to FIG. 8, the configuration of the lip 514 reduces upward vertical lift forces at least at the apex 530 and, where the leading edge 528 extends to the surface 602 (as shown) also under the lip 514.

(25) With respect to FIGS. 5-9, generally, the outermost sections (516, 520, 902, 904) of the plate 502 are structurally configured to improve stability of the plate 5020 in windy conditions. Where the outermost downward sloping section extends such that it is co-planar with the planar surface 506, the plate 502 maximizes downward vertical wind induced forces on the plate 502 while at the same time blocking wind from the outermost upward sloping section, which reduces what would have been an upward vertical force component. The outermost sections can be either linear and/or concave, which minimizes laminar flow of wind across the top surface further reducing the lift effect of air traveling over the top of the surface.

(26) FIG. 10 illustrates a variation of the configuration of the plate 502 in FIG. 5 in which parts 1000 of the first and second linear sections 516 and 520 of the lip 514 include a plurality of material free regions 1002 (e.g., holes, openings, etc.). In the illustrated embodiment, the plurality of material free regions 1002 are located about the apex 530, extend down at least a sub-portion of each of the first and second linear sections 516 and 520, and are separated by regions 1004 of the first and second linear sections 516 and 520.

(27) The illustrated plurality of material free regions 1002 are circular and have a same diameter 1006. In a variation, at least two of the plurality of material free regions 1002 have a different diameter. In another variation, at least one of the plurality of material free regions 1002 is otherwise shaped, such as elliptical, square, rectangular, etc. The number of the plurality of material free regions 1002 in the illustrated embodiment is not limiting, and other embodiments can have more or less material free regions 1002.

(28) FIG. 11 illustrates a cross-sectional view 1100 of the plate 502 along line A-A of FIG. 10. FIG. 11 is substantially similar to FIG. 6 except that FIG. 11 further shows material free regions 1002 in front of the apexes 530. FIG. 12 illustrates a cross-sectional view 1200 of a region 1008 (FIG. 10) of the plate 502 in connection with laminar flowing wind 1202.

(29) In FIG. 13, a wind component 1302 over the material free region 1002 changes a pressure over the lip 514, and the pressure gradient between the region over the lip 514 and the region under the lip 514 causes air in the cavity under the lip 514 to egress out of the material free region 1002. This reduces the pressure under the lip 514, which creates an additional downward vertical force 1304, which counteracts upwards vertical forces 408 (FIG. 4) and 806 (FIGS. 8 and 9) created due to the pressure. FIG. 15 shows a variation of the configuration of FIG. 13 in which the lip 514 includes the concave sections 902 and 904 described in FIG. 9.

(30) The configuration of the lip 514 in FIGS. 13 and 14 further reduces overall upward vertical lift forces. Again, this allows the plate 502 to maintain its location on the surface 602 and not lift from the surface 602 under wind conditions which would otherwise lift a plate, such as the plate 102, which does not include the material free regions 1002 through which air is drawn out from under the lip 514 to create an additional downward vertical lift force under the lip 514.

(31) FIGS. 15-32 show a non-limiting set of combinations of the configurations described herein. This includes combinations with at least one side which is linear or concave, with or without the leading edge being co-planar with the surface 506, these combinations with the material free regions 1002, and prior art implementations improved non-obviously with the material free regions 1002. This set does not cover all possible permutations, and the skilled artisan would understand, based on the description herein, other configurations.

(32) The application has been described with reference to various embodiments. Modifications and alterations will occur to others upon reading the application. It is intended that the invention be construed as including all such modifications and alterations, including insofar as they come within the scope of the appended claims and the equivalents thereof.
