Abstract: A welding device (10a; 10b) for welding an outlet element (12a; 12b), in particular a valve, to a packaging material (14a; 14b), has at least one, in particular self-supporting, anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, and has at least one welding die (20a; 20b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one magnet unit (22a; 22b), which is configured to at least temporarily hold the anvil (16a; 16b) in a welding position, in which the welding die (20a; 20b) is configured for welding the outlet element (12a; 12b) to the packaging material (14a; 14b)

Abstract: A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.

Abstract: A device for liquid-tight sealing of two partially overlapping packaging components. One of these is a tubular basic body. A further packaging component forms the packaging head or bottom, having at least one mandrel and one die. For the tubular basic body to be easily slid on to the mandrel and removed the expansion elements have sealing jaws which, in their working position, form a closed, encircling outer contour.

Abstract: The invention relates to a container for receiving contents, in particular liquid foods, having a tubular main body and having at least one molded fiber part connected to the main body, and to a method for producing such a container. For the container to be suitable for being aseptically filled with liquid or paste-like foods, the inner face of the at least one molded fiber part is coated to be gas and liquid tight. The container is produced as follows: pressing at least one molded fiber part from pulp, coating the inner face(s) of the molded fiber part or parts, providing the tubular main body, connecting the main body to the (first) molded fiber part for generating a container that is open on one side, filling the container through the open side, and closing the container by folding or by joining to the (further) molded fiber part.
