ABSTRACT:
A container for sterile medical liquids that has a double cap sealed closure system. A deformable thermoplastic top wall of an outer cap is spaced a distance from a top wall of an inner cap when properly sterilized. Thumb pressure on the outer cap brings the top walls of the two caps into contact. This contact provides an instant tactile test for determining that the container has been through a steam sterilization cycle and there are no leaks at the inner and outer cap seals with the bottle.
