Boxes(60) capable of being stacked in multiple stages comprise a body(62) having a space for containing articles; at least one combining groove(64) formed at two edges facing each other at a sleeve(63) formed along the upper rim of the body and provided with hanging projections protruded at the height corresponding to the level of surface of the sleeve; and a combining rib(66) protruded on the lower surface of the body and provided with a hanging groove formed at the position corresponding to the hanging projection and joined with the hanging projection, wherein both ends of the combining rib correspond to the combining groove. The combining groove and the combining rib are formed orthogonally to each other. The boxes are vertically stacked in multiple stages by joining the combining groove of one box with the combining rib of the other box.
