A container cap is provided to allow sealing up various sized containers using one type of the container cap and to allow application of the cap to various containers without special grooves or projections. A container cap(10) comprises: a cover part(11) with a size enough to a topside of a container; a close adhesion part(13) projected from the bottom side of the cover part, which includes a hooking projection established to prevent separation of the fixation ring and of which thickness increases as getting distant from the cover part; a fixation ring(12) made of a hard material, which is combined with the periphery of the close adhesion part; and a pad for sealing up generally made of rubber material.
