ABSTRACT:
A receptacle made of a starch-based biodegradable material is formed with a side wall, and a generally flat floor formed with an array of criss-cross upstanding ridges projecting from and unitary with a surface of the floor and meeting at intersections. Each rib has an undulating, generally sinusoidal, outer edge having high points spaced relatively far from the surface and low points relatively close to the surface. The ribs are positioned such that each intersection is at a high point of one of the ribs and a low point of another of the ribs.
