The actuation unit for a capping head for the application of caps on containers or bottles comprises at least two actuators, of which a first actuator is adapted to impart a translational displacement along a closing axis and a second actuator is adapted to impart a rotational movement about the closing axis, each actuator of the at least two actuators causing the rotation of a first shaft and a second shaft, respectively, both arranged coaxial to the closing axis, and is characterized in that the shafts of the at least two actuators are placed side by side along the axis and are mutually connected by means of at least one rotation decoupling joint.

The method relates to a method for filling a container (13, 32) with carbonized liquid filling material and for closing the filled container, in which the filling material is introduced in a filling station (10, 30) by a filling head (11, 33) at defined filling pressure into the container (13, 32), wherein the filling head (11, 33) is firstly moved from an idle position, which permits supplying and inserting a container (13, 32) into the filling station (10, 30), into a working position toward the inserted container, in which an end region (16) of the filling head seals off the opening (14) of the container, the container (13, 32) is then filled, the filling head (11, 33) is moved after completion of the filling phase back out of the working position into an idle position spaced apart from the container (13, 32) and the container (13, 32) is then closed in the filling station (10, 30) using a cap (20) at least enough that filling material can no longer escape, and the container (13, 32) is then removed from the filling station (11, 33), characterized in that before the movement of the filling head (11, 33) from the working position into the idle position spaced apart from the container (13), an overpressure lying between the ambient pressure and the filling pressure is set in a pressure chamber (15) of the filling station (10, 30) surrounding the opening (14) of the inserted container (13, 32), which overpressure is selected in such a way that possible foaming up of the filling material located in the container (13, 32) is minimized enough that filling material does not escape from the container (13, 32) when the filling head (11, 33) is raised out of the working position after the filling procedure.

A gripper for capping machines intended for screwing a cap onto a container adapted to being capped, in particular has a threaded neck for being capped. The gripper has a body capable of revolving on the axis of rotation, and at least two levers adapted to taking at least two different positions. The first position in which it is possible to insert a cap between the gripper levers and the second position in which the cap is locked between the gripper levers at least rotationally. At least one moving guiding shackle hinge-is mounted to the body and at least one lever which is slidingly mounted to the gripper body by means of a guide enabling movement of the lever in a horizontal direction, perpendicular to the axis of the gripper, and the end of the guiding shackle is slidingly and rotatably mounted to the at least one lever.

A capping head for applying caps on containers or bottles and a capping assembly are provided. The capping head comprises a gripping assembly having a hollow body longitudinally extending along a vertical axis and internally defining a seat for the cap, the seat being delimited at its lower end by an inlet mouth for the introduction of the cap. A moving assembly is connected to the gripping assembly for controlling the movements thereof and is hermetically separated therefrom, and an ejector member is housed inside the hollow body of the gripping assembly, in such a manner that it is free to axially slide. The ejector member carries first and second magnetic elements such that a relative axial approach of the second magnetic element towards the first magnetic element results in a translation of the ejector member towards the lower inlet mouth of the gripping assembly.

In some embodiments, a sealing and pressure dosing apparatus may be provided. The sealing and pressure dosing apparatus may include a sealing machine having one or more of a driven turret, a sealing head, a pressure sealing member, and a pressure sealing chamber. The sealing and pressure dosing apparatus may also include a pressure dosing system which may be integrated with the sealing machine.

A closing device, in particular for bottles, jars, pots or similar packaging containers for pharmaceutical or cosmetic products, having a rotationally drivable screw head for screwing a closure, for example a screw cap, onto the container which screw head has on a carrier a gripping part for grasping a closure and is actuable between a release position and a clamping position. The gripping part is embraced by a sliding cage for actuation by relative movement. Both the gripping part and the sliding cage are configured as a monolithic component and the two are intertwined in such a way that parts of the sliding cage reach through openings in the gripping part into the interior thereof and as far as a lifting apparatus in the carrier.

An apparatus for closing a container with a container closure, for example for closing a drinks container with a roll-on closure, a screw type closure, a press-on closure, a crown cap and/or a press-in closure, comprising a lifting unit which can be displaced in a longitudinal direction and which has a guide unit for predetermining a position of the lifting unit in the longitudinal direction and a closure receiving member which is connected to the lifting unit via a pretensioning device for retaining a container closure and for applying the container closure to a container opening of a container which is intended to be closed with a head pressure which is predetermined by the pretensioning device, and an adjustment apparatus for automatically adjusting the head pressure which is predetermined by the pretensioning device; it further relates to a closure member which comprises an above-mentioned apparatus.

An aluminum bottle outsert includes an annular inner surface configured to be received and supported on an upper neck portion of an aluminum bottle. The outsert also includes an annular outer surface that has a threaded portion adapted to receive a wine bottle screw top capping assembly.

A gripping assembly for a capping head for applying caps on containers, as well as a capping head, are provided. The gripping assembly comprises a hollow body longitudinally extending along a vertical axis and internally defining a seat delimited at its lower end by an inlet mouth for the introduction of a cap. An ejector member is housed inside the hollow body such that the ejector member is free to slide axially. The gripping assembly further comprises a suspension member made of magnetic material or magnetizable material, and the ejector member carries a first magnetic element that interacts with the suspension member to determine a suspension condition of the ejector member. The magnetic interaction between the first magnetic element and the suspension member is such that the suspension condition is determined only when the ejector member is brought in close proximity of or, in contact with, the suspension member.
