The disc (4) is anchored to the external upper wall of the capsule (1) during a pressing stage of the capsule (1). The capsule (1), when press-formed, exhibits the disc (4) at an upper part thereof, which prevents passage of gas through a part of the capsule (1) arranged at a mouth of a container closed by the capsule (1).</p> |
