Abstract: A removable partition for dividing a container into compartments. In a first embodiment the partition takes the form of an upper paper disk and a lower foam disk. The edges of the partition are bent upwardly such that the edge portion of the foam will contact the interior of the container, providing a much better hold than just paper. In a second embodiment, the partition is formed of upper and lower paper disks. The disks are secured together in an area spaced inwardly from the edges, such that the edges of the disks are not connected. The edges may thus be slightly spaced and provide a wider area of engagement with the inner walls of the container, providing a better hold than a single paper disk.
