<P>PROBLEM TO BE SOLVED: To provide a cap structure and a fuel cartridge using the cap structure for protecting a connector of a positive-pressure type fuel cartridge and preventing leakage of a fuel. <P>SOLUTION: The cap structure includes a support section 4A, a cap 6A, and a seal member 7A. The support section 4A is airtightly fixed in the vicinity of the connector 5 of the fuel cartridge. The cap 6A is detachably installed inside the support section 4A. The seal member 7A lies between the cap 6A and the support section 4A, and seals the connector 5. When installing the cap 6A, the connector 5 is sealed together with the support section 4A while a space is arranged between the cap 6a and the connector 5, and consequently, engagement of the cap 6A to the support section 4A is strengthened when pressure in the space is increased. <P>COPYRIGHT: (C)2009,JPO&INPIT |
