The invention enables to compress by stable stages single-piece containers produced by the modern blow forming technique, maintaining the reduction of volumes, defining as many useful volumes without requiring the containers to be altered, the latter capable of being mutually assembled, once they are compressed. The invention reduces the container (1) volume by collapsing and/or successive integration of its wall (4) segments or of the double accordion folds constituting it (10, 11, 12, 13), inside another rigidified part (5, 7, 9, 14, 16) connected to or comprising the base (16) or the opening (2, 3). The surface of the double folds comprise vertical folds and/or bellows (12, 13) whereof the temporary deformation enables one double fold to be force-folded into or onto another. The folds consists of deformable portions (10) with increasing cross-section and symmetrical orientations on either side of the folding axis (11), which is itself deformable. Their bases (9, 14, 15, 16) comprise self-locking raised parts (23, 24) and/or tabs (25). The invention is useful for manufacturers of plastic or deformable packages or containers of whatever type, whether the content is liquid, viscous, powdery, pasty or other, whatever the type of closing system, whether they are bottles, metal cans, drink cans, flasks, barrels, pots, tubes or others.
