A tamper-proof cap for bottles with a body defined by a cylindrical base, an upper closing, an anti-sliding external surface, an internal adequate thread with interrupted sections, above which there is an internal sealing layer, while its lower end has an extension equally circular, which determines the sealing belt with an outwards increase of thickness of the wall and a circular cut line with breakable parts; the sealing belt presents, right above its lower end, a series of articulated blades designed radially inwards, spaced equidistantly, as well as presenting its base configured with a dimensional detail cooperating with the articulation thereof upwards, which makes said blades operating as locking components between the cap and the bottle; each blade presents at least one anti-attrition thread or flange, further considering that each breakable element is formed by a vertical part, which, in conjunction with the weakened points, allows the sealing belt to be destroyed when removing the cap.

1. A tamper-proof cap for bottles, said cap comprising: a cylindrical single piece injected in plastic material, including: a cylindrical vertical base, including an external anti-sliding surface, an internal adequate thread interrupted by sections, a superior end completely closed by a circular wall with a round shape edge, a respective sealing layer placed against the circular wall and a lower end; anda circular sealing belt connected to the cylindrical vertical base lower end, including:a wall, presenting an outwards slight increase on the thickness;an internal surface;an external surface;an upper end;a lower end;a circular cut line above said thickening, said cut line interrupted by breakable elements; anda plurality of articulated blades adjacent to the lower end, said blades equidistantly spaced, presenting at least one anti-attrition thread radially inwards projected, a plurality of flanges and a base configured with a dimensional detail operating as a locking component between the cap and the bottle, wherein the sealing belt includes a plurality of breakable weakening points vertically accompanying the moulding of the cap, reducing the thickness of said sealing belt from the sealing belt lower end to a portion slightly above the cut line, creating vertical rupture points. 2. The tamper-proof cap for bottles as claimed in claim 1, wherein the plurality of breakable weakening points are equidistantly distributed.3. The tamper-proof cap for bottles as claimed in claim 1, wherein the plurality of breakable weakening points are not equidistantly distributed.4. The tamper-proof cap for bottles as claimed in claim 1, wherein the rupture points are formed by an internal notch and an external notch, both vertical and aligned to each other.5. The tamper-proof cap for bottles as claimed in claim 4, wherein the internal notch presents a V-type cross section, with a vertex perpendicularly directed against the thickness of the wall of the sealing belt and the external notch presents a square-type cross-section, with a bottom face vertically aligned with the vertex of the internal notch, with the rupture points between thereof.6. The tamper-proof cap for bottles as claimed in claim 4, wherein the internal notch presents a V-type cross-section, with a vertex perpendicularly directed against the thickness of the wall of the sealing belt and the external notch presents a V-type cross section, with a vertex perpendicularly directed against the thickness of the wall of the sealing belt, with the rupture points between thereof.
