A vertically swingable rear gate assembly for closing an open rear side of a shopping cart basket. The gate assembly includes a monolithic one-piece plate-like molded plastic gate member sized to substantially close off the rear side of the basket. A rigid one-piece connecting frame is disposed primarily adjacent a rear side of the gate member and includes a pair of generally transversely aligned top hinge parts for vertical hinged connection to the shopping cart. The connecting frame, adjacent an upper edge, has a downwardly-opening, transverse channel structure which engages over and confines an upper edge portion of the gate member. The lower part of the connecting frame is fixedly joined to the gate member at a location adjacent the bottom edge thereof.

A cupholder for a shopping cart includes a gate pivotally mounted to a rear portion of a shopping cart and a seat member made from a plastic material. The seat member is mounted to the gate of the shopping cart via a pivot mechanism to extend in a generally horizontal position to support a child within the shopping cart. The seat member defines a child seat portion and a cupholder positioned laterally of the child seat portion.

A basket for a shopping cart comprising a single unitary member molded from a plastic material. The basket includes a frame including a plurality of generally vertical upright frame members spaced apart from each other, with each frame member including a generally smooth outer surface without holes. A front panel extends generally vertically and laterally across the front portion of the single unitary member between two of the generally vertical upright frame members. A pair of side panels extends generally vertically, being generally parallel to each other and spaced from each other. Each side panel extends from a front portion to a rear portion of the basket between two of the generally vertical upright frame members. The front panel and each side panel comprise a generally flat portion defining a plurality of holes and have a substantially uniform thickness at least about two times less than a thickness of the generally vertical upright frame members.

A shopping cart includes a base, a pair of masts, and a basket. The base extends generally horizontally between a front portion and a rear portion of the cart and including a plurality of wheels. The pair of masts extends generally vertically upward from the base in a generally singular plane extending laterally across the rear portion of the cart. Each mast includes a rear portion facing the rear portion of the cart and defining a generally straight surface, and a front portion facing in a direction generally opposite the rear portion of the respective mast and defining a generally concave curved portion. The basket includes a front portion and a rear portion with the rear portion of the basket connected to the base via the pair of masts to support the front portion of the basket in a vertically spaced relationship over the base adjacent the front portion of the cart.

A seat assembly for a shopping cart includes a gate pivotally mounted to a rear portion of the shopping cart and a seat member made from a plastic material. The seat member is mounted to the gate of the shopping cart via a pivot mechanism to extend in a position to support a child within the shopping cart. The seat member includes a generally curved concave portion having an apex adjacent the gate and a generally straight portion on a side of the seat member opposite the apex of the generally curved concave portion.
