Definitions

  • the invention relates to a closure with a degassing device for a container opening of a container for storing and transporting, in particular, dangerous liquid filling goods, the degassing device having a gas-permeable but liquid-impermeable PTFE filter film.
  • Container closures such as screw caps for canisters or sheet stoppers for sheet drums with a thin PTFE filter film as a degassing device are generally known per se.
  • Certain liquid filling goods or chemicals such as peracetic acid (e.g. 43% peroxyacetic acid) show a very different degassing behavior with different treatment methods. When stored at rest, almost no degassing products are released.
  • the thin filter film of the degassing device is particularly useful in these cold drop tests often overstressed by the sudden surge pressure of the liquid and the film may tear and the container may leak.
  • the largest diameter being one such gas passages is less than 3 mm, it is largely ensured that the sensitive thin film is no longer overused and tears. Due to the direct contact of the support means over the entire gas cross-section, the fine tension-sensitive filter film is very well supported and the risk of overuse z. B. in the event of deflections or overexpansion due to sudden surge pressure with possible tearing of the filter film is considerably reduced; this also applies, in particular, to the low-temperature drop tests.
  • the closure according to the invention with a degassing device thus enables a higher degassing or a better escape of larger amounts of gas even at the lowest pressure build-up (without a degassing mushroom) than any known or industrially used closure with a corresponding degassing device has so far been able to. It goes without saying that the features essential to the invention shown in the various exemplary embodiments can be interchanged or combined with one another.
