Abstract: In nestable compartmentalized trays at least one portion of at least one connecting edge (formed by the converging, adjacent side walls of two side-by-side situated cup-shaped depressions constituting the compartments) is at a height from the base of the compartments that is different from the height of any other portion of the remaining connecting edges. When the trays are nested to form a stack, the abutting portions of the connecting edges of two adjoining nested trays have different heights from their associated bases. In this manner, the side walls of mutually nesting compartments are maintained spaced from one another.
