Abstract

Safety cap for bottles and containers with threaded neck, preferably made of plastic material, characterized in that, being molded in one piece, it comprises a peripheral lower ring, of larger diameter than that of the cap itself and attached to the lower edge of the latter by several junction strips radially directed outwards, so that the lower a is arranged in cantilever with respect to said lower edge of the cap and separated from it, said ring being provided on its inner side with two protuberances in the manner of teeth of saw, diametrically opposite and adapted to cooperate with corresponding projecting protuberances, also diametrically opposite in the neck of the bottle or container and which determine two teeth directed in a rotary direction opposite to that of the teeth of the lower ring of the stopper, being inclined plane and another anterior part of the stop, all adapted so that, when the cap is screwed on, in the neck of the bottle, the inclined edges of the teeth of the ring of the stopper and the neck of the bottle are faced and, by the elasticity of the material of the ring, the screwing can be continued until the teeth of the ring have exceeded the teeth of the ring. The bottle, at which time the corresponding teeth are each endowed with said teeth of a rear part in respective front and abutting opposite sides of the stop, which prevents the normal opening of the bottle or container, however it is sufficient to perform a diametrical digital pressure on the lower ring of the plug, in the sense of the diameter perpendicular to which to separate the teeth from the ring, so that, when approaching the diametrically opposite points in which the digital pressure is applied, and therefore separate the points in the teeth of the ring are found, they move outward enough to prevent the teeth from bumping against the teeth of the bot it or container remains when the cap is unscrewed, allowing the opening of the bottle or container.
