ABSTRACT:
Disclosed is a container for storing product and a process and apparatus for making the container. The container comprises a paperboard outer container and a plastic inner container which has been drawn and blow formed into the outer container. The container is characterized by plastic screw threads which extend from the plastic inner container around the upper portion of the outside of the paperboard outer container. The screw threads permit a cap to be screwed onto the container after product, e.g. food, is placed in the container. The screw threads are vacuum formed, preferably simultaneously with the blow forming of the plastic inner container.
