Patent number: 11919797Abstract: A method and apparatus for producing glass products from tubular glass precursors is provided. In particular, a method and apparatus for separating tube glass into sized glass tube portions, produced glass tube portions, glass precursor portions, or glass product portions, and their use as pharmaceutical packaging are provided. The tube glass or the glass precursor or the glass product is provided with filaments along predetermined breaking planes. The filaments extend obliquely to the local wall radius and allow for clean separation of the tube glass or the glass precursor or the glass product.Type: GrantFiled: January 9, 2019Date of Patent: March 5, 2024Assignee: SCHOTT AGInventors: Fabian Wagner, Michael Kluge, Andreas Ortner, Laura Brueckbauer, Frank-Thomas Lentes

Patent number: 11534754Abstract: A method for producing a cavity in a substrate composed of hard brittle material is provided. A laser beam of an ultrashort pulse laser is directed a side surface of the substrate and is concentrated by a focusing optical unit to form an elongated focus in the substrate. Incident energy of the laser beam produces a filament-shaped flaw in a volume of the substrate. The filament-shaped flaw extends into the volume to a predetermined depth and does not pass through the substrate. To produce the filament-shaped flaw, the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses. After at least two filament-shaped flaws are introduced, the substrate is exposed to an etching medium which removes material of the substrate and widens the at least two filament-shaped flaws to form filaments. At least two filaments are connected to form a cavity.Type: GrantFiled: April 26, 2019Date of Patent: December 27, 2022Assignee: Schott AGInventors: Andreas Ortner, Andreas Roters, Hauke Esemann, Markus Heiss-Chouquet, Fabian Wagner, Laura Brueckbauer, Stephanie Mangold, Vanessa Hiller

Publication number: 20210340051Abstract: A plate-like glass element includes a pair of opposite side faces and an opening having a transverse dimension of at least 200 ?m. The opening is delimited by an edge. The edge has a plurality of rounded, substantially hemispherical depressions that adjoin one another. The plurality of rounded, substantially hemispherical depressions having abutting concave roundings which form ridges.Type: ApplicationFiled: July 14, 2021Publication date: November 4, 2021Applicant: Schott AGInventors: Andreas Ortner, Andreas Roters, Frank-Thomas Lentes, Lutz Parthier, Markus Heiß-Choquet, Ulrich Peuchert, Fabian Wagner, Florian Resch, Laura Brückbauer, Matthias Jotz, Vanessa Hiller

Publication number: 20210340050Abstract: A method includes: providing a plate-like glass element having side faces and an ultrashort pulse laser having a laser beam; directing the laser beam onto one of the side faces; concentrating the laser beam by focusing optics to form an elongated focus in the glass element; producing a filament-shaped flaw in a volume of the glass element by a radiated-in energy of the laser beam, a longitudinal direction of which runs transverse to one of the side faces, and the ultrashort pulse laser radiates in a pulse or a pulse packet having at least two successive laser pulses to produce the filament-shaped flaw; widening the filament-shaped flaw to form a channel by exposing the glass element to an etching including an etching medium which removes glass at a rate of less than 8 ?m per hour; and introducing rounded, hemispherical depressions in a wall of the channel by the etching.Type: ApplicationFiled: July 14, 2021Publication date: November 4, 2021Applicant: Schott AGInventors: Andreas Ortner, Andreas Roters, Frank-Thomas Lentes, Lutz Parthier, Markus Heiß-Choquet, Ulrich Peuchert, Fabian Wagner, Florian Resch, Laura Brückbauer, Matthias Jotz, Vanessa Hiller

Patent number: 11091383Abstract: A plate-like glass element including a pair of opposite side faces and at least one channel introduced into the glass of the glass element. The at least one channel joins the side faces and opens into the side faces. The at least one channel has a rounded wall and a transverse dimension of less than 100 ?m. The at least one channel extends in a longitudinal direction that runs transverse to the side faces. The rounded wall of the at least one channel has a plurality of rounded, substantially hemispherical depressions.Type: GrantFiled: January 29, 2018Date of Patent: August 17, 2021Assignee: Schott AGInventors: Andreas Ortner, Andreas Roters, Frank-Thomas Lentes, Lutz Parthier, Markus Heiß-Choquet, Ulrich Peuchert, Fabian Wagner, Florian Resch, Laura Brückbauer, Matthias Jotz, Vanessa Hiller

Publication number: 20190329252Abstract: A method for the production of microfluidic cells using a disc-shaped glass element is provided. The disc-shaped glass element has a thickness of at most 700 micrometers is structured in such a way that it has at least one opening. The opening connects the two opposite-lying, parallel side faces of the glass element. The side faces are attached to a glass part so that the opening is sealed by the two glass parts to form a microfluidic cell having a cavity enclosed therein. The cavity is suitable for the conveyance of fluids. The attachment of the glass element to at least one of the two glass parts is produced by an adhesive that is applied onto the side face of the glass element. During application of the adhesive, the at least one opening in the glass element is left free of adhesive.Type: ApplicationFiled: April 26, 2019Publication date: October 31, 2019Applicant: SCHOTT AGInventors: Hauke Esemann, Stephanie Mangold, Andreas Roters, Andreas Ortner, Markus Heiss-Chouquet, Fabian Wagner, Vanessa Hiller, Laura Brueckbauer
