Abstract
Plastic container (), including a side wall () and a flexible portion () of a base (). The flexible portion of the base deflects when the sealed plastic container experiences a differential pressure. The deflection of the flexible portion of the base acts to change the internal volume of the container and thereby reduce the differential pressure. The container is a retortable container. The container may be injection-molded with inner and outer plastic layers () and a core layer () between the inner and outer plastic layers.
