Publication number: 20230106814Abstract: A hollow glass article is a container or part of a vessel having a neck or shoulder region and a wall. The glass article encompasses the wall and the neck or shoulder region of the container. The wall has a round or oval cross section and the container has a characteristic surface region on an outer glass surface of the hollow glass article. The following applies for a ratio between a mean tangential gradient value and a mean axial gradient value in the characteristic surface region: mean tangential gradient value/mean axial gradient value <0.6.Type: ApplicationFiled: December 9, 2022Publication date: April 6, 2023Applicant: SCHOTT Pharma Schweiz AGInventors: Xaver Jud, Robert Lee, Sherry Jiang

Patent number: 11565963Abstract: A hot-forming tool for producing glass containers is provided. The tool includes a forming roller, a holder, and a heat sink. The forming roller has a forming surface. The holder receives the forming roller with the forming roller rotatably mounted on the holder. The heat sink is directly or indirectly connected to the holder. The forming roller is in thermal contact with the heat sink and the heat sink has an internal cooler so that process heat can be transferred from the forming roller to the heat sink.Type: GrantFiled: January 10, 2020Date of Patent: January 31, 2023Assignee: SCHOTT PHARMA SCHWEIZ AGInventors: Marco Otero, Xaver Jud, Christian Garbini

Publication number: 20210276912Abstract: A method for shaping the mouth of a hollow precursor made of glass is provided, as well as glass produced thereby. The method includes heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth. The first and second directions are perpendicular to one another. The method can include moving the mandrel along second and/or third directions together or separate from expanding the mandrel along the second and third directions.Type: ApplicationFiled: March 3, 2021Publication date: September 9, 2021Applicant: SCHOTT AGInventors: Xaver Jud, Roman Oberhänsli, Hanspeter Kummer

Patent number: 10675407Abstract: A molding tool, a method, and an apparatus for hot forming of glass are provided that provide glass products used for pharmaceutical packaging. The molding tool includes a forming mandrel for reshaping at least a portion of a heated region of a glass precursor. The mandrel has a temperature-stable core material and an alloying element. The core material is made of precious metals, in particular of platinum group elements, and the further alloying element is made of one of tungsten, zirconium, rhodium, molybdenum, and rhenium.Type: GrantFiled: October 13, 2016Date of Patent: June 9, 2020Assignee: SCHOTT AGInventors: Joerg Witte, Xaver Jud, Alexander Humbertjean

Patent number: 10611663Abstract: A device for producing glass products for primary pharmaceutical packaging is provided. The device includes a clamping chuck for clamping a glass product, a drive for driving the clamping chuck rotatingly about a longitudinal axis thereof, and a burner for heating a glass products received within the clamping chuck. The clamping chuck has a baffle structure for generating a gas current for cooling the clamping chuck when the clamping chuck is rotatingly driven about a longitudinal axis thereof while the glass product is heated above its softening temperature for hot-forming.Type: GrantFiled: January 20, 2017Date of Patent: April 7, 2020Assignee: SCHOTT AGInventors: Alexander Humbertjean, Xaver Jud, Oliver Fruhner

Patent number: 10494288Abstract: A method is provided for reshaping a glass body rotating about its longitudinal axis. The method includes using a means for establishing a temperature profile, a radial forming tool and an axial forming tool. In the method, a first temperature profile is established and the glass body is reshaped by engaging the radial forming tool. Then a second temperature profile is established and the glass body is reshaped by engaging the axial forming tool.Type: GrantFiled: July 28, 2017Date of Patent: December 3, 2019Assignee: SCHOTT AGInventors: Bernhard Hunzinger, Michael Waschbuesch, Xaver Jud, Johannes Segner
