Definitions

  • the present invention relates to a fluid container with internal pressure, such as liquids and / or gases exerting a pressure of the interior of the container towards the outside thereof.
  • It may be, for example, containers in which the fluid exerts an internal pressure due to its own nature, such as soft drinks and / or fermenting drums, gas bottles, extinguishers or other.
  • containers in which the internal pressure exerted by the fluid comes from the pressure of a distribution network in which they are integrated such as storage water heaters, vases of central heating expansion, pool filters, sand filters, brake circuit tanks, water fountain tanks, compressed air tanks or others.
  • one of the applications relates to a use of the present invention, for example, in the brewery industry as packaged food fluids such as beer. This is not, however, limiting.
