Between the edge portion 22 and the support member 24, in turn, the ribs 28 are formed or arranged.
  • the shaft part 6 has a slightly larger outer dimension or a larger outer diameter compared to the previously shown embodiments, whereby the application area for closing the openings 2 of the sample container 3, for example to an extent between 11 mm and 14 mm can reduce.
  • Fig. 12 is a further and possibly possible independent training of the closure device 1 is shown, again with the same parts the same reference numerals or component names as in the previous Fig. 1 to 11 be used. Likewise, in order to avoid unnecessary repetition, the detailed description in the preceding is made Fig. 1 to 11 referred or referred.
  • sealing elements 12 and 16 are in turn separated by the columns 14, 18 arranged between them. It can be seen that the position of the two columns 14, 18 offset from each other seen in the direction of the longitudinal axis 5, for example, by an extent of 90 °, is selected. In each case two of these columns 14 and 18 are peripherally provided and arranged, as described above, offset from each other.
  • the universal closure device 1 is preferably made of a plastic part in an injection molding process.
  • the shortest possible hold time for the assembly plant is to be achieved, in which the closure device 1 has to be pressed against the sample container 3.
  • the air In this short period of time between 0.1 s and 1.0 s, preferably of 0.3 s, the air must have escaped through the gaps 14, 18 and / or notches 31 or openings 38, so that a pressure equalization can take place.
