A closure cap for a fluid container has a mounting part mounted on the container neck with a closure element of a given diameter fixedly positioned on the center axis thereof, and a movable part covering the container opening and movable along the center axis relative to the mounting part. The movable part has walls defining an external orifice on the center axis and an internal orifice recessed a distance inwardly from the external orifice. In one embodiment, the closure element is pulled to the closed position, and pushed to the opened position, and has a shape defining a labyrinth that creates a suction force which prevents fluid from leaking from the container when the container is righted.
