Abstract

A glass container is provided having a glass tube with a first end and a second end and a glass bottom closing the second end. The glass tube has a longitudinal axis and has, in a direction from the first to the second end, a top region, a junction region, a neck region, a shoulder region, and a body region. The top region is at the first end and has an outer diameter (dt), the neck region has an outer diameter (dn) with dn<dt, the body region extends to the second end and has an outer diameter (db) with db>dt, and the glass tube in the body region has a thickness (lb). The outer contour in a transition area between the top and neck regions is defined by a radius of curvature. The glass containers have a neck squeeze test load of at least 1100 N.
