  • Patent number: 5863145
    Abstract: The invention is directed to a container with a screwed cap for nail varnish and liquid mascara having a closed position of the screwed cap in relation to the container defined by at least one end stop and a cover rotatably fitted on the screwed cap. The container and screwed cap further have a peripheral annular shoulder (22) with a thread-like pitch formed on the outer surface of the screwed cap at an angle to the longitudinal axis of the screwed cap to produce a stop shoulder (27) on a transition region between a beginning (25) and an end (26) of the annular shoulder (22). A guide slot extends downwards from the stop shoulder (27) and aligns therewith. A guide rib having a width corresponding to a width of the guide slot (28) formed on the inner wall of the cover (7) and runs parallel to longitudinal axes (16, 17) of the screwed cap and the cover for engagement in the guide slot.
