Abstract
A filter component for a smoking article includes an upstream segment of filter material, a downstream segment of filter material in a spaced apart relation to the upstream segment of filter material so as to define a cavity therebetween, and a flavor bead disposed in the cavity. The flavor bead has an outer diameter, which is at least 75% of the spaced apart relation of the upstream segment of filter material and the downstream segment of filter material. The outer diameter of the flavor bead does not exceed an outer diameter of either the upstream or downstream segments of filter material.
