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 c1 with an outer radius r1. The outer contour of the glass syringe barrel in the shoulder region is defined by a certain minimum value the radius of curvature.
