<p>Two chamber parts (4, 5) can be pressed against each other in a sealing manner in order to receive the capsule (2). In an open position, the capsule can be held in an intermediate position between the chamber parts by means of a positioning unit (6), wherein the positioning unit (6) has, on a preferably vertical insertion plane, mutually opposite guide sections (7, 8) for guiding the capsule on mutually diametrically opposite sections of the capsule collar (3) in order to hold the capsule in the intermediate position. The insertion section is formed as a hinged guide (7) and the opposite guide section as a release guide (8). The release guide has a recess which is formed in such a way that the capsule can be rotated out of the intermediate position around the hinge guide (7) and can be released from the release guide. Before reaching the closed position, the capsule is freed from the release guide (8) in a first movement phase and from the hinged guide (7) in a second movement phase by being acted on by one of the chamber parts.</p> |
