Abstract: The modular packaging, at least two identical modular elements (1 ) which consist of walls ( 1 2) alone and have no base and which are provided with mutually interfering members (4,5). It is designed to allow stacking of a base element (2) which can be removably associated with the bottom modular element (I). At least one stable and removable member (3) is provided for fixing the modular elements(l) together. The mutually interfering members (4,5) are formed so that each stacked modular element (1) modifies the height of the packaging (10) by at least two different incremental amounts. The increment depends on the positioning of the modular element (1 ) at the top of the packaging (l0). The mutually interfering members (4,5) are asymmetrically distributed with respect to at least one vertical mid-plane for the modular elements (1).
