Shopping cart, frame, basket and production methods
First Claim
1. A modular plastic shopping cart basket comprising:
- opposed side walls, a front wall and a bottom;
an upper edge extending along the side walls and the front wall;
the upper edge having a given thickness;
a channel-shaped overlay covering at least a portion of the upper edge, the overlay being in a detachably snapped-on relationship with the portion of the upper edge, the overlay also having a generally U-shaped cross-section fitting on the portion of the upper edge and being sized so as to provide a gap between the overlay and an outer surface of the portion of the upper edge when the overlay is snapped onto the portion;
the portion of the upper edge having at least one zone of connection having a smaller thickness than said given thickness; and
a tray having a rim provided with at least one hook connectable to said at least one zone of connection to suspend the tray from the upper edge, said rim with the at least one hook being sized to fit in said gap.
