The frame is made up from four rectangular panels (1) connected by longitudinal and parallel fold lines. At each end of the panels a first flap (3) is attached by a transverse fold line that is positioned perpendicular to the longitudinal fold line.The first flap is folded against the external face of the panel to which it is connected so as to be directed away from the bottle. This forms a thickening of the external surface of the panel and prevents direct contact between the panel and package.
