Abstract

A shopping cart includes a frame, a number of front wheel assemblies and a number of rear wheel assemblies that are coupled to and support the frame, and a main container coupled to the frame. The main container includes a base, a front panel, a rear panel, and a pair of opposing side panels each having a tope edge. The front panel and the pair of opposing side panels are coupled together and extend upward from the base. The rear panel is pivotally coupled to the frame. A portion of the main container is structured to engage each of the corresponding top edges of the opposing side panels of another similarly constructed cart as the other cart is nested into the shopping cart. The engagement causes the number of rear wheel assemblies of the shopping cart to be moved from a first position to a second position generally above the first position.
