Abstract
The screw capsule includes two parts, a) an insert with a so-called internal head and an internally-threaded skirt a metallic shell, including an external head and an external skirt, the capsule being typically provided with a sealing element, a tamper-protection element and a member for first opening, characterised in that the external skirt includes at least one piece, typically cylindrical, of height, diameter corresponding to the neck for sealing and at least one radially-expanded section, of height, within a circle of diameter D2>D1, such as to form an annular radial cavity. The above offers the advantage that the expanded section particularly facilitates the manipulation of the capsule (1) and the rotation thereof with relation to the neck for opening/closing the container by unscrewing/screwing up the capsule on the neck.
