Abstract:
A filtered cigarette possesses at least one breakable capsule in its filter element. The filter element can possess a central cavity extending from the cigarette tobacco rod towards the middle of the filter element. The central cavity may be defined by an inner filter portion. The inner filter portion can be surrounded by an outer filter portion comprised of filter tow material that is generally permeable to the smoke generated by the cigarette. At least one breakable capsule is disposed in the central cavity of the filter element. The breakable capsules are spherical in shape, and are composed of a gelatin outer shell that encloses a payload of triglycerides and flavoring agents. The breakable capsules are adapted to rupture in response to pressure applied by the smoker to the outside region of the filter element.
