Abstract
A cap for covering a container, the opening of which is initially blocked by a sealed lid. The bottom of the cap is provided with a deformable part provided with a perforation means. A deformable part initially occupies a position in which the perforation means is maintained at a distance from the lid. At the moment of first use of the contianer, the deformable part is lowered to a position in which the perforation means penetrates the plane of the lid. The configuration can be used with screw-on caps, particularly with caps having tamperproof bands, or with hinged caps.
