The invention relates to a closure system constituted of a closure cap, preferably produced by plastic injection molding, and a container part that is provided with a mouth, likewise preferably produced from a plastic material. The closure cap can be screwed onto the container part and the system is provided with a tamper evidence mechanism that has to be actuated twice to be overcome. The aim of the invention is to improve said tamper evidence mechanism and its handling. For this purpose, the tamper evidence mechanism comprises an actuation tab having a twist-lock feature and being freely cut on the closure cap, and a counter-projection. Said counter-projection can be overcome by acting upon the actuation tab and is molded onto the container upstream of the counter-thread configured on the container part.

What is claimed is: 1. Closure combination comprising a closure cap and a container part, which has a mouth opening, the closure cap being screw-connectable to the container part, and an opening-securing means which requires two-fold actuation being provided, such two-fold actuation involving first pressing an actuating flap inwardly and second turning the closure cap for unscrewing the closure cap, wherein an additional part associated with the mouth opening is provided, the additional part being rotationally secured on the mouth opening but otherwise being freely removable, such that once the closure cap has been unscrewed, the additional part can be removed without obstruction from the container and in that the opening-securing means is formed with interaction between the closure cap and the additional part, wherein the additional part is configured for plug-on engagement over the mouth opening and a thread-free neck portion beneath the mouth opening in the downward direction, wherein further the threaded engagement between the closure cap and the container thread achieves clamping between the closure cap, the additional part and the container, such that even though the additional part is only plugged on loosely, the closure cap cannot be removed if the action of the opening-securing means has not been overcome, keeping the closure cap unscrewed. 2. Closure combination according to claim 1, characterized in that the closure cap comprises injection molded plastic. 3. Closure combination according to claim 1, characterized in that the container part comprises a plastic material. 4. Closure combination according to claim 1, further comprising an opposing protrusion formed on the additional part, said opposing protrusion extending perpendicularly to the plane of the container-part top. 5. Closure combination comprising a closure cap and a container part, which has a mouth opening, the closure cap being screw-connectable to the container part, and an opening-securing means which requires two-fold actuation being provided, such two-fold actuation involving first pressing an actuating flap inwardly and second turning the closure cap for unscrewing the closure cap, characterized in that the opening-securing means comprises an actuating flap, which has a rotary block and is cut free on the closure cap, and an opposing protrusion when the actuating flap is pressed radially inwardly and which is formed above the mating thread formed on the container part, wherein the opposing protrusion is formed on an additional part associated with the mouth opening, characterized in that the additional part is a closure part for the mouth, and wherein the additional part is configured for plug-on engagement over the mouth opening and a thread-free neck portion beneath the mouth opening in the downward direction. 6. Closure combination according to claim 5, characterized in that the additional part is U-shaped in a cross section with horizontal flange, outwardly directed, on the free end of the U-legs. 7. Closure combination according to claim 5, characterized in that the additional part has a closure portion which, engaging in the mouth opening from above, runs beneath a mouth plane.
