Abstract
There is described herein a disposable clam shell food service container having a continuous sidewall which includes a novel flex-hinge panel between the lid and bottom of the container. This construction permits the container to open easily when the lid is pushed upwardly resulting in a flat tray like configuration devoid of the typical upstanding median wall or divider and which may be used as a serving plate by the consumer. The container may be easily snapped closed and locked to allow later consumption of any uneaten food products. Several additional embodiments of the invention are also presented, all of which include a continuous sidewall which ensures that the food product will remain warm and one of several lock means to secure the container in its closed condition. A triangular form of the container is also described for serving of pizza, pies and similar shaped food products.
