Abstract

The present invention relates, generally, to food containers used in storing and displaying heated foods, as well as in serving foods from these containers. The food container of the present invention is an improvement over the conventional prepared food containers in that it features, among other things, an improved handle, where the heat from the container is not fully felt by the person holding the container, while still providing an advanced sealing mechanism to prevent the escape of the contents of the container.
