Definitions

  • DE-B-26 36 316 discloses a similar three-chamber filter .
  • the mouthpiece paper is provided with perforations in the area of the middle chamber, so that a ventilated filter cigarette results.
  • a mono-coaxial filter is known, which in some embodiments is also provided with holes for introducing additional air, so that a ventilated filter cigarette also results.
  • a core of cellulose acetate fibers is surrounded by a jacket made of closed-cell foam which is impermeable to the main electricity smoke, so that the main current smoke has to flow through a certain area.
  • the main current smoke of the cigarette according to the invention in its preferred embodiment due to construction and directed through the sorbent granulate particles of the chamber filter, which enables optimal gas phase sorption.
  • Figure 4 shows a section BB through the core component of the mouth-side chamber 6 of Figure 3.
  • the air-impermeable core 34 made of, for example, compressed cellulose acetate fibers is surrounded by an annular jacket 32 made of, for example, undensified cellulose acetate fibers, which are expediently air-permeable in the longitudinal direction of the filter.
  • the main flow smoke flowing centrally through the first chamber 2 after passing through the middle chamber 4 for entry into the mouth-side chamber 6 is expanded in a ring shape and flows outward in a ring shape in the direction of the arrows P.
