Abstract: A capping head for screwing screw caps onto containers includes a center axis and a capping cone having a cavity that holds a screw cap. The capping head has a toothed profile, whose teeth essentially point in the direction of center axis. The cavity has an opening. A root diameter of the toothed profile lies on a first imaginary annular surface. A tip diameter of the toothed profile lies on a secondary imaginary annular surface. The first and second annular surfaces are arranged concentric to the center axis. The second annular surface and the center axis enclose a first angle, while the diameter of capping cone increases in the direction of opening. The first annular surface and the second annular surface enclose a second angle that is greater than 0°.
