Abstract
A prefilled syringe comprises a barrel having at a distal end a needle-connecting portion and at the proximal end an open end, a plastic tubular container having a mouth and a flexible hollow cylindrical body and containing a liquid medicament previously charged therein, and a plunger inserted into the barrel through the open end thereof and slidably held therein. The tubular container is held in the barrel so that the mouth thereof is placed in a lumen of the needle-connecting portion of the barrel. The cylindrical body is peeled off from the inner wall of the barrel and squeezed into a space between the barrel and the plunger when the plunger is pushed into the barrel.
