<P>PROBLEM TO BE SOLVED: To provide a ratchet type screw cap that sufficiently exhibits an opening history indicating a function of a TE band, and effectively prevents a member coupling the TE band to a cap body from being cut when opened. <P>SOLUTION: A cylindrical opening history indicating band 2 provided at a lower end of a skirt 6 of a cap body 1 is partitioned by a vertical slit 30 into an opening side 2b positioned at an opening side of the cap and a closing side 2c positioned at a closing side of the cap. The opening side 2b and the closing side 2c are connected by a coupling part 31 that can be broken when opening the cap. An upper end of the opening history indicating band 2 and the lower end of the skirt portion 6 are coupled with each other by a strip 21 that is not broken when opening the cap and has a folded portion 21a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
