Abstract: A glass container is provided that includes a tube, a circular bottom, and a longitudinal axis. A curved glass heel extends from an outer end the bottom to the first end of the tube. The outer surface has a topography defined by a function ĥ(x) that is an azimuthal average of a distance between a contact plane and the outer surface at any given position located on a circle having the centre and the radius |x|. The values ĥ for ĥ(x) are determined for a plurality of circles the radius of which increases stepwise by 500 μm starting with a circle around the centre having a radius of 500 μm. The values ĥ are determined in a range from x=−0.4×d2/2 to x=+0.4×d2/2, d2 having a size such that at least 4 values ĥ are determined and can be fitted with a curvature function h ^  ( x ) = - c × x 2 1 + 1 - c 2 × x 2 + h 0 .

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, 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.
