Abstract

A method for manufacturing a filled syringe body within a single continuous manufacturing line in a self-contained environment with controlled conditions. The method includes the steps of injection molding the syringe body, sealing the one end of the syringe body, siliconizing the barrel of the syringe body, filling it, sealing the other end of the syringe, and sterilizing it. With this new "injection mold-fill-seal" method, a syringe body can be manufactured as a mass-produced article in one manufacturing line in an inexpensive manner.
