• FIG. 13 is an illustration of the hole pierced in the shutter 30. It can be seen that, on the one hand, an inwardly curved seal 30c is created, which is circumferential and at the same time dynamically seals. In this way, it would even be possible that the tubular body 64 in particular in the longitudinal direction can be moved back and forth and a seal between the closure 30 and the outer periphery of the tubular body 64 is formed, which seal is gas-tight and liquid-tight until pushed through and also manages without additional sealing elements.
• a further sealant to a tubular body 64, such as a disc which is disposed on the tubular body 64 and additionally presses on the closure 30 from above, for which purpose additional sealing elements, such as sealing rubbers, are placed could.
• additional sealing elements such as sealing rubbers
