  • the locking block 27 is arranged to adopt one or the other of a high position and a low position.
  • the locking block 27 when it is in the low position, blocks the rotation of the toothed crown 82 so as to maintain the second levers 80 in their hooking position. Conversely, when the locking block 27 is in its high position, the latter releases the toothed wheel.

Mechanismus nach Anspruch 6, wobei das dritte Verriegelungsmittel einen Blockierstift (26) und einen außerhalb der Zelle angeordneten Verriegelungsblock 27 umfasst, wobei der Blockierstift so angeordnet ist, dass er entweder eine erhöhte Position oder eine niedrige Position einnimmt, wobei der Blockierstift (26) seine erhöhte Position einnimmt, wenn sich der Verriegelungsarm (31) in seiner ersten Position befindet, und seine niedrige Position einnimmt, wenn sich der Verriegelungsarm in seiner zweiten Position befindet, wobei die niedrige Position des Blockierstifts (26) eine Position ist, in der der Stift über einen Verriegelungsblock (27) eine Blockierung der Zahnkrone bewirkt.
  8. Mechanismus nach einem der Ansprüche 1 bis 7, wobei die Zellentür (30) im Bezug auf ihre erste Fläche eine vorstehende radiale Krone umfasst, die so angeordnet ist, dass sie, wenn die Behältertür (4) an die Zellentür (30) anliegt, das Entriegelungsmittel der Behältertür (4) betätigt.
  9. Mechanismus nach Anspruch 8, wobei das Entriegelungsmittel eine bewegliche Oberfläche einer flexiblen Membran der Behältertür (4) umfasst, durch die eine von der radialen Krone ausgeübte Kraft auf Sperrriegel übertragen wird, um diese Riegel aus einer Innennut des Behälterflansches (1) auszuklinken und so die Behältertür (4) zu entriegeln.
  10. Mechanismus nach einem der Ansprüche 1 bis 9, wobei der Fangmechanismus in der zentralen Nabe (36) angeordnet ist.
  11. Mechanismus nach Anspruch 10, wobei der Fangmechanismus an der Basis der zentralen Nabe (36) einen Satz beweglicher Sperrklinken (38) umfasst, die so angeordnet sind, dass sich, wenn der Verriegelungsarm (31) von seiner ersten Position in seine zweite Position übergeht, die Behälter- und die Zellentür dazwischen zentriert und blockiert, wobei die Spitzen der beweglichen Sperrklinken (38) in eine Innennut eines zentralen Gehäuses der Behältertür (4) eindringen.
  12. Mechanismus nach einem der Ansprüche 1 bis 11, wobei der Mechanismus ein zweites Verriegelungsmittel umfasst, das, solange die Behältertür (4) nicht gegen die Zellentür (30) gedrückt wird, jedes Schwenken der zentralen Nabe (36) blockiert.
  13. Mechanismus nach Anspruch 12, wobei das zweite Verriegelungsmittel einen Riegel umfasst, der zwischen einer dritten Position, die das Schwenken der zentralen Nabe (36) blockiert, und einer vierten Position, die das zentrale Mittel freigibt, schwenkt, wobei das zweite Verriegelungsmittel ferner einen Verriegelungsstift umfasst, der in Bezug auf die erste Fläche vorsteht und bewirkt, dass, wenn er von der zweiten Fläche unter Druck gesetzt wird, der Riegel von seiner dritten Position in seine vierte Position schwenkt.
  14. Mechanismus nach einem der Ansprüche 1 bis 13, wobei eine Behälterdichtung zwischen einem Teil der Kontaktfläche des Behälterflansches (1) und der Kontur der Behältertür (4) platziert ist, um die Dichtheit des Verschlusses des Behälters gegen die Zelle sicherzustellen.
  15. Mechanismus nach einem der Ansprüche 1 bis 14, wobei eine Zellendichtung zwischen einer Innenbohrung des Zellenflansches (20) und einem Teil der äußeren Dichtungsfläche der Zellentür (30) platziert ist.
