Abstract:
1. A capping head for screwing screw caps onto containers, the capping head comprising: a center axis; and a capping cone comprising an inner surface defining a recess for accommodating a screw cap, a toothed profile with axially aligned teeth, each of said teeth having a base and a tip, wherein the tip extends from the base in an inwardly radial direction, the recess having an opening, a diameter of the capping cone increasing toward the opening; wherein the toothed profile is defined by a first annular reference surface coplanar with the base of said teeth, and a second annular reference surface tangential with the tips of said teeth, wherein a height of the teeth is defined by the distance between the first annular reference surface and the second annular reference surface; wherein the first and second annular reference surfaces are arranged concentric to the center axis and diverging from each other approaching the opening, such that the height of said teeth increases in the direction toward said opening; wherein the second annular reference surface and the center axis enclose a first angle; and wherein the first annular reference surface and the second annular reference surface enclose a second angle, the second angle being greater than 0°.
