Abstract

Safety closure for bottles, characterized in that it consists of endowing the neck of the bottle, in its extreme part, with three peripheral reliefs, in the form of rings, located at different heights, the lower one of which, of triangular section, is located in the base of the neck in parallel and above a flat flange of greater amplitude than the relief and close to it, while the other two reliefs are located near the mouth; arranged in parallel, the upper one being triangular section and the lower section rectangular, both cut by two notches diametrically opposed and offset by 90º one relief with the other, assisting in the closure a capsule that fits inside the neck of the bottle and is provided with a flat flange that limits the penetration, which flange is cut radially by triangular incisions that determine the formation of fins, weakened in their start of the capsule, by whose weakening they are bent, with possibility of recovery by the characteristics of the plastic material of the molding, by means of the action of a tubular sleeve that adjusts said fins on the outside of the neck in the space between the embouchure and the first triangular relief, whose tubular sleeve is provided at its lower end with an axial extension of greater diameter provided internally with a flange intended for crimping pressing into the lower triangular flange of the neck abuts the flat flange, acting as a seal; this prolongation being connected to the sleeve through a climbing line that allows its tearing facilitated by another radial climbing and actuation flap to unseal the closure, while the cylindrical sleeve is provided in its inner middle part with radial teeth by which is adjusted, in a first position for its retention between the upper rings, retaining the fins of the capsule, eliminated the lower area of the seal, said moves vertically downwards, passing the teeth through the notches of the rectangular relief of the neck, for release the fins of the capsule and be able to use the contents of the bottle, extracting the sleeve by vertical upward sliding, saving the teeth of the two reliefs, through a 90º turn, to return to the retention of the capsule by its placement and folding of the fins with the passage of the sleeve in reverse operation, to cause a new eventual closure of the bot she.
