A child-resistant cap comprises: an inner cap mounted at a vessel inlet of a vessel; an outer cap disposed at an outer circumferential surface of the inner cap so as to perform an idling with the inner cap; a rotation force transmitting portion disposed between the inner cap and the outer cap for transmitting a rotation force of the outer cap to the inner cap only when the outer cap is downwardly moved with a force more than a certain degree; and a sealing member removing unit formed at the inner cap for removing a sealing member sealed at the vessel inlet when the inner cap is detached from the vessel inlet, and storing the removed sealing member in the inner cap. Since the sealing member removing unit is integrally formed at the cap, the sealing member is automatically removed at the time of opening the cap. Accordingly, the sealing member needs not to be additionally removed, and thus a usage convenience is enhanced. Furthermore, under a construction that the outer cap maintains an upwardly moved position from the inner cap by an elastic force, the cap can be opened only by downwardly moving the outer cap with a force more than a certain degree. Accordingly, a child can be more effectively protected.
