Abstract:
A disposable plate formed from a mineral-filled polyolefin sheet comprising:a substantially planar center portion; a first rim portion extending outwardly therefrom, said first rim portion being upwardly convex and subtending a first arc with a first radius of curvature; a second rim portion joined to said first rim portion, and extending outwardly therefrom, said second rim portion being downwardly convex, subtending a second arc with a second radius of curvature; third rim portion joined to said second rim portion and extending outwardly therefrom, said third rim portion being downwardly convex, subtending a third arc with a third radius of curvature; and, a fourth rim portion joined to said third rim portion and extending outwardly therefrom, said fourth rim portion being downwardly convex subtending a fourth arc having a fourth radius of curvature, wherein the length of said second arc of said second rim portion is substantially less than the length of said fourth arc of said fourth rim portion which, in turn, is substantially less than the length of said first arc of said first rim portion and wherein said fourth radius of curvature of said fourth rim portion is less than said third radius of curvature of said third rim portion which, in turn, is less than said second radius of curvature of said second rim portion and wherein the angle of said first arc is greater that about 55 degrees and the angle of said third arc is greater than about 45 degrees.
