The present invention relates to a container cap comprising an inner cap and an outer cap. The inner cap has a second cylindrical portion and a joint portion. The second cylindrical portion has an open top, and a lower side end which is to be inserted into a neck, and which has a plurality of outlet ports for discharging additives. The joint portion protrudes from the outer circumference of the top of the second cylindrical portion and is detachably joined to a stopper protrusion of the neck. The outer cap has a first cylindrical portion and a threaded portion. The first cylindrical portion is slidably coupled to the inner surface of the second cylindrical portion from the inner surface of an upper plate in a surface-contacting manner, and the lower end thereof extends axially to close the plurality of outlet ports. The threaded portion extends axially from the outer surface of the upper plate to be fastened to the outer surface of the neck. When the outer cap is partially opened, said outlet ports are opened to introduce the additives from a receiving space into the main body of a container. When the outer cap is fully opened, the inner cap is separated from the main body of the container together with the outer cap. |
