Abstract
A plastic open frame basket is made by molding from plastic material, a tapered body portion, having integrally interconnected smoothly contoured longitudinal rib members and cross members in an interconnected, open frame configuration. A plurality of raised diagonal parting lines extend between said outer and inner corners formed by adjacent cross members to define a stepped configuration, thereby enabling the resulting plastic molded open frame basket to be made from a relatively inexpensive mold apparatus.
