PURPOSE: A container cap is provided to enable a user to easily assembly an outer cap and an inner cap through one push operation, to be easily reused by enabling the user to conveniently wash the container cap, and to improve convenience by separating the inner and outer caps from the container. CONSTITUTION: A container cap comprises an outer cap which is screwed with a neck(6) of the container and an inner cap which is combined with the inner part of the outer cap and includes an accommodation space(1a) for an additive(A). A skirt(10a) is included on the lowest part of the outer cap. The skirt is integrated with the outer cap and is separated when the container cap is opened. Multiple protrusions are included on the inner circumference of the skirt for the snap bond with a ring-shaped blocking protrusion(6c).
