Abstract
Improved delivery of additive materials to cigarettes is provided through the use of one or more oval capsules containing releasable additive materials, such as flavor components, in the filter section of a cigarette. The oval capsule or capsules are provided between first and second absorbent members and have the long axis thereof arranged parallel to the longitudinal axis of the cigarette. When the capsules are subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material and expose the additive material to mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and other cigarettes components, such as sorbents or filter materials, in order to reduce additive material migration into the other cigarette components prior to desired use. An outer cover which is impermeable to the releasable material within the capsules is provided about the capsule or capsules and the first and second absorbent members.
