A cap comprises a cap body fitted and secured to the mouth of a container, an upper closure provided in the cap body, and a ring-like member which covers the outer surface of a skirt portion of the cap body. The ring-like member and the skirt portion are coupled together through breakable bridge portions. These two members are separated away from each other via cut surfaces but are intimately contacted to each other at the cut surfaces. The cap can be easily removed by hand from the mouth of the container, and can be separated from the container at the time of disposal.
