Patent number: 5569438Abstract: In an apparatus for treating, for purposes of sterilization, a continuous material web a first treatment station is provided and includes a device for bringing a material web into contact with liquefied hydrogen peroxide. A second treatment station is also provided in which the material web is simultaneously sterilized with hydrogen peroxide vapor and dried with heated air after treatment of the material web in the first treatment station. The second treatment station includes an elongate chamber having an inlet and outlet, the material web being dried and thereby generating hydrogen peroxide vapor as it is led through the elongate chamber from the inlet to the outlet. The second treatment station also includes an outer flow duct in flow communication with the inlet and outlet of the elongate chamber.Type: GrantFiled: February 17, 1995Date of Patent: October 29, 1996Assignee: Tetra Laval Holdings & Finance S.A.Inventor: Anders Hilmersson

Patent number: 4704509Abstract: An arrangement for the sealing of thermoplastic-coated packing material of the type which includes at least one layer of an aluminum foil. The arrangement includes an inductor (3) connectable to a high-frequency source of current which is constituted of a U-shaped loop of electrically conducting material. The legs of the U-shaped loop are parallel and are situated close to each other, and the inductor (3) a core (10) of ferrite material between its legs. The core of ferrite material has local inserts (11) of ferrite material of substantially higher permeability than the surrounding portions of the core (10) and the local inserts (11) are installed in regions of the sealing arrangement where strong local heating is required in the sealing joint or where the sealing pattern needs to be influenced.Type: GrantFiled: August 13, 1986Date of Patent: November 3, 1987Assignee: Tetra Pak International ABInventors: Anders Hilmersson, Gert Holmstrom, Hans Selberg

Patent number: 4617779Abstract: The manufacture of non-returnable packages is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming the filled packing containers to the desired shape. During the forming, which is done by external forming devices, the contents are used as a mandrel or a holder-up for the forming device, so that the desired shape can be achieved without creasing or other deformations. The above-mentioned forming principle works less well if the packing containers are not completely filled, but have a certain air space or headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome by the invention wherein a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents.Type: GrantFiled: September 9, 1983Date of Patent: October 21, 1986Assignee: Tetra Pak International ABInventors: Jan Nygren, Anders Hilmersson

Patent number: 4512935Abstract: The presterilization of packaging machines for the manufacture of aseptic packing containers can be carried out with the help of sterile air and liquid sterilizing agent, which are blended so that a gas saturated with sterilizing agent of a suitable temperature and dew point is obtained. In order to achieve a rapid and effective volatilization of the liquid a circulating movement is imparted to the hot sterile air as the sterile liquid is introduced into the center of the circulating movement. An apparatus using this method comprises a chamber with a helical guide rail and a spray nozzle for the sterilizing liquid.Type: GrantFiled: January 13, 1984Date of Patent: April 23, 1985Assignee: Tetra Pak International ABInventors: Anders Hilmersson, Jan Lagerstedt, Helge Andersson
