ABSTRACT:
The lunch box comprises a generally square base container and a correspondingly shaped cover each being integrally formed from the same polymeric material. The base container has an integral handle extending forwardly from one side and integrally formed hinge tabs extending rearwardly from an opposite side. The cover, in turn, has integrally formed hinge blocks with slots for receiving the hinge tabs. The arrangement is such that in open position, the top of the cover is coplanar with the bottom of the base container so that both cover and container can engage a flat surface and function as serving trays for contents in the box. In a second position, wherein the box is closed, the cover is simply swung by flexing of the hinge tabs over the top of the container to close the upper opening. The container and cover openings include cooperating lip and step structures providing an hermetic seal and also frictionally holding the cover in place on the container.
