A cap (V) for bottles (2) of injection liquids (substance 1) or the like has a sealing disk (D) capable of being pierced arranged between the bottle neck (3) and a closing ring (5) that surrounds the opening of the bottle and has a central opening (12). A supporting surface that faces the centre (Z) of the sealing disk (D) allows the sealing disk (D) to be easily pierced and at the same time securely retains it on the bottle opening.
