  • the encapsulated articles in question generally comprise a container or capsule containing a predefined dose or amount of a particular product or reagent substance, for example tobacco, or other substance to be inhaled, and a filter.
  • the aspirating or inhaling action produced by the user creates a stream of aspirated air in which the vaporized or atomized liquid is drawn, forcing it to pass through said reagent substance.
  • This passage extracts or draws flavoring substances and/or active ingredients contained in the same reagent substance which are then aspirated or inhaled by the user.
  • the product and the filter are kept in position by means of special closing elements which prevent the product and/or the filter from exiting, but at the same time allow the passage of vapors, fumes and/or aromas to the outside.
  • capsules are known containing a dose of tobacco, and a filter, which can be used in suitable devices, or electronic cigarettes, provided with means for heating the tobacco dose.
