<p>Capsule (1) for receiving a medium, comprises: a capsule lower part (2), in which the medium is incorporated; and a capsule upper part (3) attached on the capsule lower part. The capsule lower part comprises an outwardly curved, inner hollow ridge around its entire periphery. The capsule upper part is attached on the capsule lower part up to the ridge, and welded with the ridge. Independent claims are also included for: (1) producing the capsule filled with the medium, comprising providing the capsule lower part and the capsule upper part, reshaping the capsule lower part to form the outwardly curved, inner hollow ridge around the entire periphery of the capsule lower part, and welding the capsule upper part with the ridge; and (2) an arrangement for producing the capsule filled with the medium, comprising a cavity divided at least into two parts, where the cavity comprises a circumferential annular groove as a negative shape of the ridge to form the ridge around the entire periphery of the capsule lower part, and the arrangement is formed for applying a vacuum in the annular groove.</p> |
