ABSTRACT OF THE DISCLOSURE A safety closure, preferably for a medicine bottle, has a screw cap or other closure cap which is to be rotated to be applied or removed, and a blocking mechanism in the form of an elastically resilient blocking member on the bottle neck or a collar securely mounted on the neck, and a stop face on the closure cap. The cap has an area of reduced wall thickness which is opposite the blocking member in the closed position and permits the blocking member 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 member and prevents additional rotation, unless the blocking member is pressed clear of the stop face by pressure on the closure cap. The blocking member is elongate and merges at both ends into the bottle neck or collar, but is spaced from the neck or collar at its central portion, which has a blocking face. This allows the blocking member to retain its tendency to return to the blocking position after actuation, even though the elasticity of the material decreases after many operations.
