<P>PROBLEM TO BE SOLVED: To provide an airtight cap structure which can secure airtightness by bringing a cap into contact closely with an end part to be applied, even in case there is a possibility that the end part to be applied may be relatively inserted into a cap with some angle or offset. <P>SOLUTION: A cap 16 is made up of an outer cap 22 and an inner cap 24 installed inside the outer cap 22. In addition, the inner cap 24 is fitted to the outer cap 22 in the way that the former 24 can be freely tilted to a center axis of the cap 16, and thereby, when the cap 16 is used, the inner cap 24 can be brought into contact closely with the end part to be applied 12 or its periphery. <P>COPYRIGHT: (C)2007,JPO&INPIT |
