<P>PROBLEM TO BE SOLVED: To provide a cap whose nozzle part can be perfectly sterilized, when being sterilized easily and securely dried after sterilization, and is hardly contaminated by microorganisms during use, and a pre-filled drug solution container to be equipped therewith. <P>SOLUTION: A pre-filled syringe comprises a syringe body having a nozle arranged on the distal side end of a columular body, and a cap for covering on the nozzle. The cap comprises a cap main body and a rubber film. A through-hole is formed on the central part of the distal end of the cap main body. The through-hole comprises a large diameter part 311 which is positioned to the distal end side and has a constant inner diameter, a small diameter part 313 which is positioned to the proximal end side and has an inner diameter smaller than that of the large diameter part 311, and a taper part 312 which is positioned between the large diameter part 311 and the small diameter part 313 and has a inner diameter made gradually smaller toward the proximal end. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
