Abstract
Disclosed is a pre-filled plastic syringe containing a liquid product for terminal sterilization comprising: a syringe barrel equipped with a one-way valve and a slidable plunger to equalize pressure differentials; a filter engaging the one way valve to prevent backward migration of viruses and bacteria; an end cap covering the open end of the barrel to maintain sterility; and an end cap restraining device to prevent plunger blow-out.
