Abstract
A package structure is disclosed. The structure comprises a lid and a base, both of a flexible material which is relatively reistant to elongation and compression. The lid and the base are movable relative to one another between an open position and a closed position. The lid has a central, substantially planar lid panel, and lid channel means which is integral with, and extends about a major portion of the periphery of, the lid panel. The base has a generally flat base panel, and a stepped base wall which is integral with, and extends completely around the periphery of, the base panel. When the lid and the base are in a closed position, the channel means and the step of the stepped base wall abut one another. The structure also includes a base insert adjacent the base panel, interior of said stepped wall. The insert is sufficiently stiff and extends into sufficiently close proximity with opposed portions of the base that it is operable to strengthen the base against flexing.
