Abstract
Described is a capping head for closing a container using a metallic cap, comprising a main body, a plurality of capping ends having on their inner face a capping profile and a capping ring configured for elastically deforming the plurality of capping ends by means of a relative translation along the longitudinal axis.
Claims11
A capping head for closing a container using a metallic cap, comprising:
- a hollow main body which extends around and along a longitudinal axis of the capping head;
- a plurality of capping ends, integral with the main body and positioned below the main body in an axial direction along the longitudinal axis, each of the capping ends, having a capping profile on an inner face thereof facing towards the longitudinal axis;
- a capping ring, positioned outside the main body, movable along the longitudinal axis relative to the capping ends and configured for elastically deforming the plurality of capping ends through the relative movement along the longitudinal axis;
- wherein each adjacent pair of the capping ends includes one capping end having a predominately concave capping profile as viewed in the axial direction and another capping end having a predominately convex capping profile as viewed in the axial direction, thereby defining a circumferential alternation around the capping head of the predominately concave capping profile and the predominately convex capping profile.

A capping method for closing a container using a cap comprising the steps of:
- providing a capping head comprising:
- a hollow main body which extends around and along a longitudinal axis of the capping head;
- a plurality of capping ends, integral with the main body and positioned below the main body in an axial direction along the longitudinal axis, each of the capping ends, having a capping profile on an inner face thereof facing towards the longitudinal axis;
- a capping ring, positioned outside the main body, movable along the longitudinal axis relative to the capping ends and configured for elastically deforming the plurality of capping ends through the relative movement along the longitudinal axis;
- wherein each adjacent pair of the capping ends includes one capping end having a predominately concave capping profile as viewed in the axial direction and another capping end having a predominately convex capping profile as viewed in the axial direction, thereby defining a circumferential alternation around the capping head of the predominately concave capping profile and the predominately convex capping profile;
- positioning the cap with a relative side wall positioned around a neck of the container;
- positioning the container below the capping head in the axial direction and along the longitudinal axis;
- positioning the capping head above the container with the capping ends positioned around the cap;
- moving the capping ring downward along the longitudinal axis for elastically deforming the capping ends radially inward to plastically deform the cap with the capping ends, thereby sealing the cap on the container.
