<P>PROBLEM TO BE SOLVED: To provide a syringe also serving as a vessel with a simple structure capable of being manufactured at low cost in a small number of production processes. <P>SOLUTION: This syringe is the syringe also serving as the vessel having the structure wherein an inner vessel 3 is housed in bellows-shaped outer vessel 2, and a medical solution is sealed inside the inner vessel 3 to use as the syringe. A vessel body 1 is formed by covering the outside of the inner vessel 3 to be filled with the medical solution with the outer vessel 2, and a stopper member 4 is fitted into a port part 7 of the vessel body 1 to seal the port part 7. A needle installation part 44 for installing a needle is formed on the stopper member 4. The outer vessel 2 of the vessel body 1 is bored with ventholes 23 for introducing outside air into between the inner vessel 3 and the outer vessel 2. When the inside of the outer vessel 2 becomes a negative pressure, the ventholes 23 open to introduce the outside air. <P>COPYRIGHT: (C)2004,JPO |
