Zusammenfassung:	A childproof closure for a screw topped container comprises a combination of a thread on the bottle which features >=2 ramps along an external thread path and a (plastic) cap having an internally threaded skirt with internal ribs which can interfere with the ramps on the bottle neck. The ramps and ribs meet back to back for easy closure, but interlock during unscrewing. The interference can be overcome by distorting the cap skirt profile, by applying radial pressure at suitable points pref. indentified by marks or flats on the outside of the closure.
