Definitions

  • the invention relates to a donor. With it, liquid, powdery, gaseous and / or pasty media ins Free are given.
  • the medium becomes one Media outlet replaced by the donor.
  • the donor is with to carry the same single hand and for media delivery to operate.
  • a pump, the valve can be used as the discharge conveyor a pressure container such as an aerosol container or the like be provided.
