A plurality of axially extending cuts are circumferentially spaced in the skirt portion of the cap proper, and the skirt portion of the cap proper and the ring-like member are separated via a cutting surface, but are integrally formed via a plurality of frangible bridge portions or connecting portions upwardly or downwardly of the cutting surface. The outer surface of the skirt portion of the cap proper and the inner surface of the ring-like member are intimately adhered at a portion of the cutting surface. This cap can form a sealing structure having sealing reliability, and can be opened without using any particular tool. Furthermore, it has excellent tamper-evident characteristics.
