Abstract: The multiple level carton box assembly consists of a series of open carton boxes, stacked one on top of the other so that the base (5) of each carton box acts as a serving tray and also becomes the cover of the adjacent carton box below. The carton boxes are secured to each other by means of vertical interlocking tongues (7C, 9C) extending above the front back side walls (7, 9) of each carton box which are inserted and wedged into the slots (7D, 9D) on the base (5) of the adjacent carton box above thus interlocking and stabilizing the assembly of carton boxes. Stability of the embodiment is attained by the folding corners (1, 2, 3, 4) which due to the double fold provide firm support of the adjacent carton box above as well as the horizontal semicircular tongues (7E, 7F, 9E, 9F) of each carton box which provide added support to the adjacent carton box above and thus prevent bending or collapsing of the embodiment.
