Abstract:
A collapsible container, particularly a cup or mug having a flexible body having a top tier, middle tier and a bottom tier is disclosed. The bottom tier has a base. The container has a first living hinge between the top and middle tiers and a second living hinge between the middle and bottom tiers. A rigid, preferably metal, plate is at least partially embedded in the bottom tier that makes the otherwise flexible base rigid. The container can have a rigid metal cladding around the top tier and a handle made of flexible material. The collapsible container may be made by injection molding.
