Abstract
Abstract An apparatus for forming a lid around an open top of a container in which the lid of the container is a flat sheet. The lid is placed over and centered on the open top of the container, and overlaps the sides of the container. The container is raised into a die-forming assembly which folds down the overlapping ends of the flat lid around the container. Glue is applied to the overlapping ends of the lid while the ends are being folded to secure the ends of the lid around the container.
