Abstract
A dual walled insulating paperboard container is disclosed. The container preferably includes an inner cup and an outer cup each having tapered sidewalls. The sidewalls, however, have different angles of taper to provide an insulating cavity therebetween. Additionally, the bottom of the inner cup is spaced from the bottom of the outer cup to create an insulating barrier along the bottom of the container. The outer cup also includes a stepped region along its top that cooperates with a curled top edge of the inner cup to provide another insulating cavity along the top of the container.
