  • Section 1404 shows encapsulated flavorant power incorporated into the cellulose acetate filter (on the plugwrap) and rolled under pressure to varying degrees.
  • Deposition of encapsulated flavor materials in or on the surface substrates that can be incorporated into the plug wrap have the added benefit of not loading the actual filter tow with a finely divided material, and thus avoiding potential manufacturing difficulties or undesirable effects on the filter performance, such as pressure drop.
  • FIG. 15 illustrates the effect of particle size and agglomeration, and particle hardness on menthol released from cigarettes equipped with the novel flavor delivery system disclosed herein.
  • Data indicate that an optimal, preferable primary particle size, aggregatesize, and agglomeration size exist with respect to the physical nature of the filter material. For example, effective menthol release was observed using finely divided non-agglomerated encapsulated powders as compared to agglomerated powder under the same conditions.
  • the physical nature of the flavor containing material must not impact or alter the overall intended function of the filter (i.e. delivery of total particular material, air dilution, etc.).
  • Material F provided no response to the rolling while applying pressure technique as it is a material very similar in characteristics to the those beads used in cigarettes implementing a crushing technique, such as is described in U.S. Pat. No. 7,836,895. This material responds to pressure at much greater forces than applied in practice of this invention. The beads were not crushed prior rolling and did not release any flavor under the rolling while applying pressure technique.
  • a finely divided powder containing the payload is incorporated in the filter tow or inside of the plugwrap or tipping paper.
  • the user can hold the cigarette by the filter and firmly roll the filter between his fingers. Few and/or more gentle rolls will produce less release of flavor than more and/or stronger rolls.
  • agglomerated powder or larger size non-agglomerated particles is incorporated with or without a shell coating. This provides for no-release (off) if the treatment were not applied and more varied formulations for control can allow for quick decrease in the amount of flavor released if a person doesn't roll the cigarette again (for dial down of flavor).
