发明名称 Plastic shopping cart
摘要 A plastic shopping cart is disclosed. In accordance with certain aspects of the present invention, all of the components of a shopping cart are formed from a moldable material such as, for example, a thermoplastic resin by means of an injection molding process or the like. The shopping cart is configured so that any metallic parts that are used to connect the various plastic components together are shielded from the ambient environment. This virtually eliminates any rusting and corrosion of any metallic parts that are used to connect the various components of the shopping cart together.
