ABSTRACT:
A partitioned and foldable paper food container which is suitable for containing different foods in different compartments and can be folded into a flat rectangle for easy carry and storage. The food container is made of pure fiber paper meeting FDA regulation and is formed in such a manner that the paper is first cut into a predetermined pattern, then embossed with folding lines, then folded and finally heat sealed or adhered. The food container includes a main compartment and two subsidiary compartments integrally extending from two end edges of the main compartment, whereby after folded and sealed, the subsidiary compartments can be received in the main compartment to form a partitioned food container for containing different foods in different compartments and thereby prevents the taste of the foods from mixing with one another.
