Smoking article with downstream flavor addition

Abstract

A smoking article that comprises at least one substrate material section having an aerosol precursor composition associated therewith, a flavor addition component, and a mouthpiece disposed downstream from the at least one substrate material section, the mouthpiece including a filter. In one implementation, the mouthpiece may include the flavor addition component, and the flavor addition component may comprise a plurality of flavor beads proximate a hollow flow tube, the flow tube including a plurality of peripheral openings defined therethrough. In another implementation, the mouthpiece may include the flavor addition component, the filter may define a cavity therein, the flavor addition component may comprise a plurality of flavor beads, and the plurality of flavor beads may be located in the cavity.

         4 . The smoking article of  claim 1 , wherein the flavor addition component is disposed downstream from the filter. 
     
     
         5 . The smoking article of  claim 1 , wherein the plurality of peripheral openings of the flow tube comprises a plurality of holes extending through a peripheral wall of the flow tube. 
     
     
         6 . The smoking article of  claim 1 , wherein the plurality of peripheral openings of the flow tube comprises a plurality of slots extending through a peripheral wall of the flow tube. 
     
     
         7 . The smoking article of  claim 1 , wherein the flow tube extends through at least a portion of the filter. 
     
     
         8 . The smoking article of  claim 1 , wherein the plurality of flavor beads comprises at least one of tobacco flavor beads, non-tobacco flavor beads, gel flavor beads, capsules containing flavor beads, or any combination thereof. 
     
     
         9 . The smoking article of  claim 1 , wherein the filter defines a cavity, wherein plurality of flavor beads are located in the cavity, and wherein the flow tube extends through at least a portion of the filter. 
     
     
         10 . The smoking article of  claim 1  further comprising a second substrate material disposed between the first substrate material and the mouthpiece. 
     
     
         11 . The smoking article of  claim 1 , wherein the substrate material comprises at least one of tobacco-containing beads, tobacco shreds, tobacco strips, pieces of a reconstituted tobacco material, or tobacco rods. 
     
     
         12 . A smoking article comprising:
 at least one substrate material section having an aerosol precursor composition associated therewith;   a flavor addition component; and   a mouthpiece disposed downstream from heat source and the at least one substrate material section, the mouthpiece including a filter,   wherein the mouthpiece includes the flavor addition component, wherein the filter defines a cavity therein, wherein the flavor addition component comprises a plurality of flavor beads, and wherein the plurality of flavor beads are located in the cavity.   
     
     
         13 . The smoking article of  claim 12  further comprising a heat source, and wherein the heat source is disposed proximate at least a portion of the at least one substrate material section. 
     
     
         14 . The smoking article of  claim 12  further comprising a device separate from the smoking article, wherein the separate device includes an electric heat source configured to heat at least a portion of the at least one substrate material section. 
     
     
         15 . The smoking article of  claim 12  further comprising a hollow flow tube, the flow tube extending through at least a portion of the filter. 
     
     
         16 . The smoking article of  claim 15 , wherein the plurality of flavor beads substantially surround the flow tube. 
     
     
         17 . The smoking article of  claim 15 , wherein the flow tube includes a plurality of peripheral openings defined therethrough. 
     
     
         18 . The smoking article of  claim 17 , wherein the plurality of peripheral openings of the flow tube comprises a plurality of holes extending through a peripheral wall of the flow tube. 
     
     
         19 . The smoking article of  claim 17 , wherein the plurality of peripheral openings of the flow tube comprises a plurality of slots extending through a peripheral wall of the flow tube. 
     
     
         20 . The smoking article of  claim 12 , wherein the plurality of flavor beads comprises at least one of tobacco flavor beads, non-tobacco flavor beads, gel flavor beads, capsules containing flavor beads, or any combination thereof.
