  • the one-way lock is destroyed, one Foil is, for example, withdrawn or (for example from the fluid coupling) pierced.
  • the gas-permeable region is preferred as an opening in the film formed with a liquid-tight and gas-permeable material is closed. It can In particular, this is a nonwoven that the low Outgassing easily pass through, without to create an impermissible overpressure in the canister. On the other hand, it is sufficiently densely woven or knitted to liquid or not at best in small Let drip quantities pass. Suitable nonwovens are For example, woven or knitted fabric of synthetic fibers, the gas, but are not liquid-permeable. Such materials are known to the skilled person. For example. are suitable as nonwovens PTFE membranes available under the name Gore-Tex®.
  • the connection between the fleece and the film takes place for example, by gluing or welding.
  • the film is preferably a composite film Aluminum or an aluminum alloy and a thermoplastic Material, for example polyethylene.
  • the fleeces may also comprise a thermoplastic material or coated with it.
  • the fleece then overlaps placed on the opening in the film and the overlapping Edges become with the application of heat welded together.
  • the welding or gluing may be formed weaker in an edge region (for example through a narrower area in which a Gluing or welding takes place), so that when Piercing the foil with the fluid coupling in the area of the fleece this weakened connection area a Predetermined breaking point represents.
  • the fleece will be first solve at this breaking point of the film and thus by defined folding away the opening for the fluid coupling release.
  • the film can also tear down in the area of this connection. This embodiment avoids that when piercing the fleece or parts hang it from the leading end of the fluid coupling or stick and pressed into the recording, so that no tight fluid connection between fluid coupling and recording comes about.
  • the area of the fluid coupling is preferably designed such that that ensures that when inserted the fluid coupling between this and the rest of the Foil in each case an air gap remains.
  • the purpose must be to ensure that the cross-sectional area the pierced foil area in each case larger is as the cross-sectional area of that area of Fluid coupling, which in the inserted state of the Enclosed film. In other words, it must be prevented be that the remaining after piercing foil remainder the fluid coupling or extraction line flush and thus encloses airtight.
  • the opening in the covering film is preferably axially aligned arranged with the receptacle for the fluid coupling.
  • Axially aligned means that the opening on the Axis is the fluid coupling and the associated Holder for the fluid coupling in the direction of attachment connects with each other. Since the cover usually a closes circular opening is accordingly the Opening usually arranged centrally on the cover.
  • the receptacle for the fluid coupling is preferably in arranged an insert which can be inserted into the removal opening is.
