Abstract
A shopping cart comprises a wheeled chassis, a handle structure including two handle uprights, and a plastic basket comprising separate side, front, and bottom panel members molded from a suitable plastic and assembled without any need for an interior frame. The side and front panel members have tabs. The front and bottom panel members have slots. The tabs are received by the slots to assemble the panel members. A rim wire has side portions received by wire-receiving formations of near top edge portions of the side panel members and a bight portion bearing against a top edge portion of the front panel member. The side portions are bent to form prongs inserted into apertures in the handle uprights to position the basket before the basket is fastened to the handle uprights and to the wheeled chassis.
