<P>PROBLEM TO BE SOLVED: To provide a cap which has a structure in which attaching the cap to a liquid storage vessel securely retains hermetic seal until unsealing of the vessel and also securely prevents a liquid leak, and which prevents the inside of the vessel from being contaminated after the vessel is unsealed. <P>SOLUTION: The cap comprises a base member 7 which can be attached to a vessel body 10 with the liquid storage part 12; an over-cap 8 which can be fitted to the base member 7; a push-in member 9 which has in its side a groove 91 for guiding a liquid medicine to outside, and can be pushed in the vessel body 10 in order to release the vessel body 10 from hermetic seal; and a first close contact member 11 included by the base member 7 so as to allow the flow of the liquid medicine. The cap further comprises a filter member 101, and a venting means 100 with a check valve 103 which has an opening 102 that allows the inflow of air and does not allow the outflow of the liquid medicine. The venting means 100 is disposed in such a position as to communicate with the liquid storage part 12 after the release of the vessel body 10 from the hermetic seal. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
