Definitions

  • the invention relates to a ventilated multifilter for a Rauchartikei with at least two filter segments, wherein at least one filter segment comprises a component to be dispensed to the smoke component and at least one further filter segment comprises a sorbent, which receives at least one component of the smoke stream, and at least one Fiitersegment at least one recess having the peripheral surface
  • cigarette filters which are provided, for example, with activated charcoal particles, which absorb unwanted substances from the cigarette smoke. It is also possible that certain substances desired in cigarette smoke, such as flavorings, are disadvantageously removed from the cigarette smoke. This can negatively affect the taste of the cigarette.
  • the smoking article filter according to the invention has at least two filter segments.
  • the first filter segment comprises a component which is discharged to a passing through a filter outlet smoke stream
  • a second filter segment comprises a sorbent, which receives at least one component from a passing through the filter inlet opening smoke stream.
  • the term "ingestion” is understood to mean both the adsorption of the component on the sorbent (adsorption) and the absorption of the component in the sorbent (absorption). In the broadest sense, any binding of the component to be removed by the sorbent should be referred to as "uptake”.
  • a filter segment is thus mixed with a sorbent or a substance, so that one or more undesired components are completely or partially removed or "filtered out” from the smoke stream.

  • the second filter segment is arranged between the tobacco rod and the first filter segment.
  • the smoke stream coming from the smokable material is first passed through the second filter segment and cleaned of unwanted components, the smoke stream then passing through the first filter segment where it is subsequently spiked with a desired component before ultimately exiting the smoking article.
  • the reverse case is also conceivable, namely that the unfiltered smoke stream is first mixed with a component to be added and only then unwanted components are removed from the smoke stream.
