Abstract

A food box comprises a base and a cover, the cover and the base each is formed on their edge thereof with an annular engaging portion, respectively, the engaging portion of the cover is employed to be engaged with the engaging portion of the base. Each of the engaging portions of the base and the cover are a protruding structure located around the periphery of the base and is formed in its bottom with a groove, and each of the engaging portions is in such a shape in cross section that its upper part is smaller than its lower part. When two bases or covers are stacked up, the distance between the two neighboring bases or the two covers is less than the height of the engaging portion of a single base or a single cover, thus substantially reducing the required storage space of the product while improving the transportation volume.
