Patent ID: 7228980

Claim:
A plastic capsule for closing a large bottle, said capsule comprising: an upper surface; a cylindrical wall projecting coaxially from below said upper surface to form an openable zone that is accessible from outside said capsule and through which a liquid contained in a large bottle may be removed; a cap closing said openable zone at the end of said cylindrical wall opposite said upper surface; a disc being located above said openable zone, coplanar to said upper surface, made in a single piece with said capsule, and peripherally connected to said cylindrical wall of said openable zone by easy-break ribs such that an annular space is defined between said disc and upper surface; an annular skin hermetically sealing said annular space, wherein said annular skin is made in a single piece with said capsule and is formed thinner than said disc and said ribs such that said skin is rupturable; and an external annular hoop forming an outer lateral wall of said capsule extending coaxially below said upper surface and having a larger diameter than said cylindrical wall, wherein said external annular hoop rests on an annular projection of a neck of a bottle when said capsule is mounted on a bottle, said external annular hoop rests on said annular projection in such a way so as not to project laterally from said neck.
