Abstract (en)
The closure (10) comprises a substantially cylindrical cork-based part (12) and a circular diaphragm (14) applied coaxially to that face (16) of the cork-based part (12) intended to lie inside the bottle (11). The diaphragm (14) is of plastic material suitable for contact with foods and has a diameter less than the maximum diameter of the cork-based part (12), but greater than the inner diameter of the neck of the bottle (11). The diaphragm (14) comprises: a coaxial circular first portion (18) of diameter just greater than the inner diameter of the relative neck part of the bottle (11), such that the first portion (18) interferes with the interior of the neck of the bottle (11) to provide a first seal; and, to provide a second seal, a more external annular second portion (20) forming a single piece with the first portion (18) and coaxial thereto. The second portion (20) has a thickness decidedly less than that of the first portion (18) at least with regard to that zone of this latter (18) closest to the second portion (20).
