ABSTRACT:
Top cone for an aerosol can, including a formed metal sheet extending around a longitudinal central axis, and having a contour that includes, as seen in longitudinal cross section from the top downward, a top section intended for holding a valve cap, a cone section connected to the top section and leading to a countersink section and a flange section. The countersink section is essentially U-shaped whereby the outer leg of the essential U-shape, that is the leg being furthest removed from the central axis, is bent away from the central axis to form the flange section, and which cone section has a continuously increasing transversal diameter, wherein the top cone comprises strengthening means for strengthening the countersink section against pivoting toward the central axis.
