1. A terminally sterilizable container comprising:
- a polypropylene bottle having a body with a manually squeezable sidewall with a thickness preventing more than about 6% water loss over a period of about 24 months, the bottle having a threaded neck with a neck diameter smaller than a body diameter;
said body having a top rounded shoulder below the neck, a concave bottom with a bottom rounded shoulder subtending said concave bottom and said sidewall, the top and bottom shoulder having radii providing autoclave produced pressure distribution and deformation resistance;
an elongated tip snap fitted to said neck and having a lumen therethrough in fluid communication with said body and a drop dispensing orifice; and
a threaded cap engaging said threaded neck and having a cap body enclosing said elongated tip and a closed end with a nub sealing the orifice preventing autoclave produce pressure leaks.
