<p><P>PROBLEM TO BE SOLVED: To provide a stop plug of a container which can well prevent a liquid from spilling when sticking a needle or withdrawing a needle even after elevated temperature and high-pressure sterilization. <P>SOLUTION: A plug body 2 which has a larger outside diameter than the inside diameter of an outside cap 1, comprises a thermoplastic elastomer and can stick a needle, is pressed and fitted into the outside cap 1. Since by this, the plug body 2 is in a condition that has internal stress always compressed by the outside cap 1, when sticking the needle into the plug body 2 even after elevated temperature and high-pressure sterilization, since the elastic restoring force by compressed internal stress closes this even if this sticking part is cut and opened, internal liquid does not leak. Also, since this part is closed by the elastic restoring force caused by the compressed internal stress even after withdrawing the needle from the plug body 2, the internal liquid does not leak. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
