Abstract
An integrally-formed plastic basket, moldable in a two-piece injection mold, combines light weight, strength, and large carrying capacity. Thin side walls with a draft no greater than 3.degree. are formed with overlapping cross-members. Between a pair of unslotted, substantially planar cross-members is a slotted, corrugated cross-member. Interior slots are formed by the core die of the injection mold, while exterior slots are formed by the cavity die.
