An object of the present invention is to be capable of closing a cap body even if the cap body is opened and in a lock state. A cap body (12) is in a closed state by interlocking of a lock button (18) and a button interlocking member (91). The lock button (18) is disposed at a main cap body and can undo the closed state of the cap body (12) by exerting force from the outside. The button interlocking member (91) is disposed at the cap body (12). A lock driving member (20) interrupting the operation of the lock button (18) is formed adjacent to the lock button (18), and the cap body (12) may be in a closed state by a temporary evacuation operation of the button interlocking member (91) while the lock driving member (20) interrups the operation of the lock button (18) while the cap body (12) is opened, such that the cap body (12) may be closed even if the lock button (18) is in the lock state due to the button interlocking member (91) performing the temporatry evacuation operation. |
