Described herein is a capping head for the application of caps on bottles or containers, in which the capping head is enclosed within a casing (31) having an end mouth (32) that engages the bottle or the container during application of the cap so as to define a closed chamber, within which the capping head is contained. Said closed chamber is set in communication with a source of vacuum so as to empty the bottle or container of the air contained therein before completion of application of the cap.
