Abstract (en)
The invention disclosed herein consists of a screw-thread for bottles with asymmetrical neck, of among the screw-threads which define the exact position of the element to be screwed on: a cap without symmetry, or a spray gun. The invention is conceived so that in all cases it permits the user to introduce the screw-thread at any angle and the end (9.3) of the screw-thread to be reached and therefore its correct position. The use is combined of a single entry screw-thread plus a section (9.2) without helical pitch and a set of projections (10) which increase the pressure and friction of the cylindrical body to be screwed on. This pressure and the greater friction produced are what prevent the unscrewing whilst avoiding the need to overcome the particular force necessary in the solutions habitually employed to surpass anchoring projections (10).
