发明名称 Food container
摘要 A food container suited for use in carry out food service having a base and cover. Each container portion is of tapered construction to permit stacking upon itself for storage and each has stop members formed thereon to determine stack height. Catch structure is formed on the cover which interlocks with resilient lip structure formed around the upper periphery of the base to detachably lock the container and base in an assembled state. The container base forms a shallow hollow of sufficient depth to prevent spillage, but is sufficiently flat to permit use as a plate which can be eaten upon with knife and fork. The resilient lip structure defines, when interlocked with the cover, vents which provide air circulation in the closed container to prevent condensation therein. Formed on the top of the cover and the bottom of the base is interfitting structure operable to retain one assembled container stably stacked on another with food contained therein. The container portions are preferably made of inexpensive heat insulative material to keep food warm and also be disposable.
