Abstract:
1. A cigarette comprising: a tobacco rod; a filter element having an outer cylindrical shape connected to the tobacco rod, said filter element having an end proximal to the tobacco rod and an end distal from the tobacco rod; a cavity having walls defined by said filter element, and extending from the proximal end of the filter element, wherein the cavity possesses a generally conical shape at a first end and a generally cylindrical shape at a second end proximal to the tobacco rod; and at least one breakable capsule affixed in the cavity by friction between the capsule and the walls of the cavity, said capsule comprising an outer shell comprising gelatin and an internal payload in the form of an anhydrous liquid or gel comprising a flavoring agent and a diluting agent, the diluting agent comprising a triglyceride, wherein said filter element incorporates cellulose acetate treated in a manner that results in the filter element being sufficiently flexible to be squeezed to break said capsule while also being sufficiently resilient to return to a substantially cylindrical shape and maintain said cavity after being squeezed.
