• a lower part (1) coupled to the mouthpiece (5),
• a plate (2) that can be latched to the lower part (1) for closing the lower part (1), to which the mouthpiece (5) can be latched, and a capsule holder (3) that can be countersunk in the lower part (1) for receiving the capsule,
• a cover (6), which covers the mouthpiece (5) in a closure position and latches by means of a closure element, where the lower part (1), the plate (2), the mouthpiece (5) and the cover (6) are pivotably joined together by a single joint (7), and
• an actuating member (8), which can be set in motion from a resting position, thereby cooperating with at least one pin (9) that can be pushed into the capsule holder (3).
