1. A glass container, comprising:
i) a glass tube with a first end, a further end, an outer diameter (d1) and a glass thickness (s1);
ii) a glass bottom closing the glass tube at the first end and comprising an inner surface directed to an inside of the glass container and an outer surface directed to an outside of the glass container; and
iii) a curved glass heel extending from an outer end of the glass bottom to the first end of the glass tube;
wherein the glass container is characterized by a longitudinal axis (Ltube) that passes through a center of the glass bottom;
wherein for any cut surface of the glass container that is obtainable by cutting the glass container in a plane that includes the longitudinal axis Ltube a minimum thickness (smin) and a maximum thickness (smax) of the glass bottom determined at any position having a distance d1/4 or less to longitudinal axis Ltube and a thickness (sd1/4) is the thickness of the glass bottom determined at a position having the distance d1/4 to the longitudinal axis Ltube, the distance to the longitudinal axis Ltube in each case being determined in a direction that is perpendicular to the longitudinal axis Ltube and thicknesses smin, smax and sd1/4 being determined in a direction that is parallel to longitudinal axis Ltube,
wherein smax/smin is less than 1.8;
wherein the glass container has an overflow capacity of not more than 9 ml, wherein the overflow capacity is a maximum volume of liquid that the glass container can hold if filled to the point of overflowing;
and wherein the following conditions are fulfilled:
s1×sd1/4 is in a range from 1.1 to 2.5 mm2 and sd1/4 is in a range from 1.1 to 1.4 mm.
