Abstract
The invention concerns a closure comprising a base portion and a cap forming portion including a top articulated to a ring through a hinge. The strap enables the cap forming portion to be moulded in closing position of the top, tamperproof means being provided between the ring and the top. When the cover is closed, the sensitive zones of the cap are either located in a sealed closed space, or capable of being in contact with a liquid (in solution or spray) and capable of being treated so as to eliminate said liquid, so as to sanitize the closure. Furthermore, the tamperproof means are deformed and ruptured when the top is first opened such that the resulting free ends are sufficiently spaced apart from each other, thus easily revealing to a user whether it has been tampered with.
