STEP-WALL NESTABLE CUP ABSTRACT A step-wall nestable cup provided with offset thin sidewall portions which overlap to define an annular intermediate thickened wall portion which strengthens the cup while permitting the use of relatively thinner wall portions thereabove and therebelow. The use of off-set overlapping thin wall sidewall portions also permits the use of a lower density plastic material without increasing the stack height of the nesting cups while resulting in significant material and/or shipping cost savings without sacrificing overall sidewall strength of the resultant nestable cup or con- tainer. A modified step-wall nestable cup is provided with multiple off-set thin sidewall portions which respectively overlap to provide a plurality of annular thickened sidewall portions in the sidewall thereof.
