Abstract
A safety closure cap having a first closure member and a second closure member rotatably retained therein. The second closure member may be screwably attached to a container, so that the cap closes the container by rotation of the first closure member in the closing direction, the two closure members being coupled together for this purpose. For removing the cap from the container the cap is provided with a further coupling arrangement which can be engaged when the two closure members are moved together, rotation of the first closure member in a direction opposite to the closing direction causing simultaneous screwable rotation of the second closure member from the container.
