1. A container assembly for accommodating pharmaceutical compositions, comprising:
a container having a hollow cylindrical body having a constant outer diameter along its length with an open end and a closed end opposite to the open end, the closed end being closed by a bottom portion, the hollow cylindrical body and the bottom portion being formed integrally and of a common material, which is a glass or polymer material, the hollow cylindrical body having a length (L) between 35 mm and 120 mm, an outer diameter (Do) between 8.65 mm and 30 mm, and an inner diameter (Di) between 4.65 mm and 27 mm;
a length to outer diameter ratio between 3:1 and 15:1;
an inner surface of the container having an average Zn-leachability of 0.00135 μg/cm2 or less; and
a solid plunger having no holes or empty spaces within and having a length, a first surface, a second surface and a perimeter along the length with an outer surface in the open end to sealingly close the inner surface of the open end to define sealed area, wherein the solid plunger is pierceable by a cannula and is slidable on the inner surface from the open end towards the closed end, and wherein the outer surface of the perimeter of the solid plunger completely contacts the inner surface of the hollow cylindrical body.
