Abstract: A detachable capsule-breaching head for a beverage-mixing device. The capsule-breaching head comprises a capsule 48-container body having a first body part which is telescopically movable on an actuation axis A relative to a second body part. The capsule-breaching head further has at least one capsule-receiving chamber in the first body part and a capsule-breaching element at the second body part movable relative to the capsule-receiving chamber on the actuation axis A. A discharge guide element guides a powder released from a capsule, an openable closure element sealingly closes the discharge guide element, and a removable access cover closes an access opening of the capsule-receiving chamber.
