Abstract
A disposable flavored filter attachable to the mouth end of a cigarette comprises an insertion end and a mouth end. A first interior portion of the filter, at and adjacent to the insertion end, defines a void space of the filter, while a second interior portion of the filter, at and adjacent to the mouth end, defines one or more segments. In a single-segment embodiment of the invention, flavorant is injected into, or a flavor-containing capsule is inserted into, the single segment. In a two-segment embodiment of the invention, the flavorant is injected into, or the flavor-containing capsule is inserted into, that segment disposed between the void space and the segment at the mouth end of the filter.
