<p>The present invention aims at maintaining the sterilized condition of a drug-containing syringe, preventing such a syringe from being used with evil intent, simplifying the packaging of such a syringe, protecting a drug stably and making such a syringe suck an additional liquid, such as narcotic or a dissolving liquid properly and aseptically thereinto prior to injection. To achieve these objects, the present invention is constructed as follows. The portion of a syringe which extends from a cap (11) fitted around an injection needle fixing portion of an injection barrel (1) to a base end head (23) of a piston rod (22) is covered with a seal member (31) consisting of a tube (32) of a thermally shrinkable film, and the seal member (31) is closely fitted around the injection barrel by thermally shrinking the same, whereby the injection barrel (1) in which a drug (5) is sealed, a piston (21) and piston rod (22) are shut off from the outside air. The portion of the injection barrel (1) which is between the front and the rear ends of the piston (21), which has finished sealing the drug (5) therein in cooperation with the cap (11) and placed in a predetermined position in the injection barrel (1), is provided with an indication (3) of a limit of drawing the piston (21). <IMAGE></p> |
