Disposable container, of the type wherein at least part of the lateral surface of the container (1) consists of a bellow- shaped structure comprising a plurality of adjacent folds joined by internal (2) and external (3) hinge bands, respectively. At least the internal hinge bands (2) have, in a cross-section, a lobed structure comprising mutually alternate ridges (4) and valleys (5) which are continuously joined, the ridges and the valleys of one of said internal hinge bands (2) being offset, in the projection on a perpendicular plane to the container axis (A) , with respect to the ridges and valleys of the immediately surrounding internal hinge bands . In correspondence of said ridges there are further provided shape stiffening areas (6) of the bottle wall. Each of said stiffening areas (6) is joined to the surrounding stiffening areas by slanting ribs (8) . |
