The capsule for closing containers comprises a first cap (2) provided with an outlet mouth for the liquid in the container, screwed on to mouth (3) of a container. An annular element (6), coupled to the first cap (2) has a lower part which is destined to detach on first opening of the capsule. The first cap (2) can assume a closed lower position, in which the outlet mouth is closed by an upwardly-projecting part of an obturator (8), and an upper open position, in which the outlet mouth is distant from the projecting part. A second cap (11), external to the first cap (2), is internally provided with a projection (12) coupled with the first cap (2) and optionally located on an easy-break security strip. The capsule guarantees an airtight seal, especially for containers of gassy liquids. |
