<p>A safety closure, preferably for a medicine bottle, has a screw cap (20) or another closure cap which is to be rotated to be applied or removed, and a blocking mechanism in the form of an elastically resilient blocking means (16) on the bottle neck (11) or a collar securely mounted on the neck, and a stop face (26) on the closure cap. The cap has an area (27) of reduced wall thickness which is opposite the blocking means in the closed position and permits the blocking means to be actuated by external pressure on the cap. When the cap is rotated in the direction of removal from the closed position, the stop face encounters the blocking means and prevents additional rotation, unless the blocking means is pressed clear of the stop face by pressure on said area of the closure cap.</p><p>The blocking means (16) is a string or strip merging at both ends into the bottle neck or collar, but is spaced from the or collar at its central portion having a blocking face (17), and this allows the blocking means to retain its tendency to return to the blocking position after actuation, even though the elasticity of the material decreases after many operations.</p> |
