  • Patent number: 10433578
    Abstract: There is provided a filter (103) for a smoking article (100). The filter (103) comprises a filter segment (201) comprising filter material, and the filter segment (201) has a cross sectional area measured perpendicular to the longitudinal direction of the filter (103). The filter further comprises a flavor delivery member (205) embedded in the filter segment (201) and surrounded on all sides by the filter material (203). The flavor delivery member (205) comprises structural material enclosing liquid flavorant for flavoring smoke during smoking of a smoking article provided with the filter (103), and the flavor delivery member (205) releases at least a portion of the liquid flavorant when the filter (103) is subjected to external force. The cross sectional area of the flavor delivery member (205) measured perpendicular to the longitudinal direction of the filter (103) is about 30% of the cross sectional area of the filter segment (201) or greater.

    Abstract: Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

  • Patent number: 8459272
    Abstract: Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

  • Patent number: 8353811
    Abstract: A large variety of electroprocessed capsules can be produced to encapsulate a variety of additives within the subcompartments or substructures of the manufactured capsule. Furthermore, the manufactured capsules can be arranged within a filter of a smoking article during the manufacturing process. By modifying the various parameters that control the electrospraying or electrospinning processes, capsules can be manufactured that vary in composition, in substructural organization, and in dimension. A capsule produced by electrospraying comprises at least one polymeric material that encapsulates or supports the retention of at least one flavorant and/or non-flavorant within the capsule. A polymeric material provides a supporting structure for encapsulating at least one flavorant and/or non-flavorant additive.

  • Patent number: 8322350
    Abstract: An aerosol generator device for delivering an aerosol of a nicotine salt is provided. The aerosol generator comprises: (i) a mouth end; (ii) a first chamber containing a porous material wetted with liquid nicotine, (iii) a second chamber containing a porous material wetted with a solution of a volatile acid, (iv) a third chamber in fluid communication with the first and second chambers, leading to the mouth end, and (v) an outer housing defining a passageway for air through said device. A nicotine vapor can be produced by drawing air along the passageway and through the porous material wetted with liquid nicotine. An acid vapor can be produced by passing air along the passageway and through the porous material wetted with a solution of a volatile acid. Then, the nicotine vapor and the acid vapor can be admixed in the third chamber to form an aerosol of a nicotine salt, which can be drawn out through the mouth end.

  • Patent number: 8286642
    Abstract: Improved delivery of additive materials to mainstream smoke produced by smoking articles is provided through the use of a temperature sensitive powder containing an additive material, such as a flavor component, in a smoking article such as a cigarette. The temperature sensitive powder is subjected to heat which causes the temperature sensitive powder to release at least a portion of the additive material into mainstream smoke. The temperature sensitive powder encapsulates the additive materials and other portions of the smoking articles, such as sorbents or filter materials, in order to reduce additive material migration during storage.

  • Publication number: 20120255569
    Abstract: The invention provides a cigarette with a filter element comprising at least one longitudinally extending section of filter material. The section of filter material comprises a smoke-altering material therein that is useful for removing a quantity of vapor phase chemicals from the mainstream smoke. The section of filter material further comprises one or more tubes inserted into and extending through section of filter material. The one or more tubes each define a channel adapted for passage of mainstream smoke through the section of filter material while substantially avoiding contact of the portion of mainstream smoke therein with the smoke-altering material. The provision of a portion of mainstream smoke substantially unaltered by the smoke-altering material can be useful to retain certain desirable taste and other sensory properties of the mainstream smoke.
