  • Publication number: 20240042136
    Abstract: A glass syringe barrel is provided that has a bottom end and a top end with a cone region, a shoulder region, a body region, and a flange region therebetween. The glass syringe barrel is configured so that f(x) defines an absolute value of a vertical distance between any point of a first outer contour and a straight line fo at a position x, with f(x)=0 at point P1, wherein x is a horizontal distance between any given point on the straight line fo and point P0 at which the straight line fo crosses a line L1 that runs parallel to the longitudinal axis and that touches an outer surface of the body region, and a maximum value for the term f(x) in a range from x=P0 to x=P1 is f(x)max determined at position xmax.

  • Patent number: 11833334
    Abstract: A glass syringe barrel is provided that has an at least partially conically shaped upper portion and a longitudinal axis. The glass syringe barrel has a top end through which a liquid can be ejected and a bottom end into which a plunger stopper can be pushed. The glass syringe barrel includes, in a direction from the top end to the bottom end, a cone, a shoulder region, and a body region. The shoulder region has and outer contour that has a concave and substantially circular arc-shaped area ci with an outer radius r1. The outer contour of the glass syringe barrel in the shoulder region is defined by a certain value for r1.

  • Publication number: 20210276912
    Abstract: 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.

  • Publication number: 20120272683
    Abstract: A method for shaping a floor of a glass vessel, including the steps of bringing the floor region of the glass vessel up in temperature until the viscosity of the glass in the floor region is between 1010 dPas and 103 dPas thereby defining softened glass. Moving a porous gas emitting shaping floor toward the floor region from a side opposite an orifice of the glass vessel. Displacing some of the softened glass by way of a gas film as the softened glass is approaching the porous gas emitting shaping floor. And, increasing an amount of the floor of the glass vessel that is resting on the gas film as the softened glass is approaching the porous gas emitting shaping floor, the gas film preventing direct contact between the softened glass of the floor of the glass vessel and the porous gas emitting shaping floor.
