<P>PROBLEM TO BE SOLVED: To provide a method to seal a medical container to prevent bacteria and foreign matters from mixing in and to unseal the sealed container without leaving foreign matters such as cut chips of the sealed container, and the medical container used for the method. <P>SOLUTION: The medical container 1 adopts a sealing method to weld a synthetic resin film 5 to the surface of a mouth part 3 to seal the opening part 4 of the mouth part 3. The synthetic resin film also can be welded by ultrasonic vibration, high-frequency dielectric heating, and a laser, The unsealing method adopts a way to cause melt-shrink of the synthetic resin film 5 by hot air, radiation heat, laser, high-frequency dielectric heating, electromagnetic induction, cutting off, peeling off. <P>COPYRIGHT: (C)2004,JPO |
