• a first container configured to store a first product preparation component;
• a second container;
• and
• a closure device comprising a coupling apparatus connected to a closure element that comprises a fastening sleeve and a closure cap, the closure element being configured to couple to the first container such that the closure cap seals an opening in the first container, the coupling apparatus being configured to couple to the second container, and the closure device being configured to establish a fluid connection between the first container and the second container when the closure cap is separated from the fastening sleeve and detached from the first container,
• wherein (1) axial movement of the coupling apparatus relative to the closure element is prevented, (2) rotation of the coupling apparatus relative to the closure cap is prevented, and (3) rotation of the coupling apparatus relative to the fastening sleeve is permitted for at most one rotation, and
• wherein the closure cap is configured to be completely separated from the fastening sleeve along a predetermined break point while the fastening sleeve is connected to the first container.
