ABSTRACT:
The present invention is directed to a plastic container having a reinforcing ring disposed around its upper edges to provide additional strength. The reinforcing ring is preferably formed of a cross-sectionally round wire which is obtained from a coil, straightened, cut, and bent to suitable dimensions. If desired, the reinforcing ring may have its ends welded together and the ring may extend around the entire top opening. The reinforcing ring is disposed within a peripheral outwardly facing channel of the shopping cart basket, crate, or other container. The channel includes top and bottom walls and an inner side wall. The reinforcing ring is free of projections that engage the walls of the channel. The channel has retaining ridges and/or a plurality of resilient discrete projections which retain the reinforcing ring and enable the reinforcing ring to be snap-actingly receivable within the channel.
