Patent number: 11872188Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information regarding origin and manufacture of the glass tube semi-finished product and a second marking, the information of which second marking is linked to the information of the first marking, so as to enable a determination regarding authenticity of the glass tube semi-finished product, origin of the glass tube semi-finished product, and/or origin of an apparatus with which the first and/or second marking was generated on the glass tube semi-finished product. The first marking is a marking that is produced at temperatures above the transformation temperature of the glass in a counterfeit-proof manner. The combination of two markings provides a high level of protection against counterfeiting.Type: GrantFiled: December 8, 2017Date of Patent: January 16, 2024Assignee: SCHOTT AGInventors: André Witzmann, Ulla Trinks, Reinhard Männl

Patent number: 11542195Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information on the origin and/or tube-specific production data of the glass tube semi-finished product, which marking is read from the hollow glass product after its manufacture to determine the origin and/or the tube-specific production data of the glass tube semi-finished product, e.g., to identify the semi-finished glass tube from which the hollow glass product has been made, and/or trace the tube-specific production data of this glass tube semi-finished product. This means that the entire supply chain for the hollow glass product from the supplier of the originally used glass tube semi-finished product up to the end product can be determined. The physical and chemical characteristics of the glass tube semi-finished product are not altered for producing the first marking.Type: GrantFiled: December 8, 2017Date of Patent: January 3, 2023Assignee: SCHOTT AGInventors: André Witzmann, Ulla Trinks, Reinhard Männl

Publication number: 20200002212Abstract: A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.Type: ApplicationFiled: September 9, 2019Publication date: January 2, 2020Applicant: SCHOTT AGInventors: Reinhard Maennl, Stephan Tratzky, Franz Jaeger

Publication number: 20190308899Abstract: The present invention relates generally to a process for producing glass products and to an apparatus suitable for the purpose. In the process, a melting apparatus is provided with a melting tank for producing a glass melt from glass raw materials and a top furnace. Part of the surface of the melting region of the melting apparatus is covered with the glass raw materials and at least a small portion of the surface of the melting region is uncovered. In addition, energy is introduced in such a way that a vertical temperature difference can be established, such that the temperature of the glass melt at the base is greater than the temperature of the atmosphere in the top furnace.Type: ApplicationFiled: April 9, 2019Publication date: October 10, 2019Applicant: Schott AGInventors: Stefan Schmitt, Wolfgang Schmidbauer, Christian Müller, Frank-Thomas Lentes, Michael Hahn, Reinhard Männl, Hildegard Römer, Karin Naumann

Patent number: 4250687Abstract: Packaging of tubes or rods is disclosed. The tubes or rods consist of a brittle material such as glass or ceramics. In a method for packaging, the tubes or rods are arranged in one package in the tightest possible packaging form. This package is encased by a hood preferably consisting of a film of synthetic material which is fitted over the package under stress and which thereby locks the tubes or rods in position. A plurality of such packages can be stacked on a conventional pallet and can be encased by an additional hood locking this stack in position.Type: GrantFiled: May 2, 1978Date of Patent: February 17, 1981Assignee: Schott-Ruhrglas GmbHInventors: Hartmut Lueneberg, Reinhard Maennl, Alfred Grillmeier
