Cigarettes and filter subassemblies with sqeezable flavor capsule and methods of manufacture

Cigarette filter subassembly and method for manufacturing it. The invention relates to the improved delivery of cigarette additive materials through the use of one or more capsules (36) containing additive materials, such as flavor components, within the filter section (26) of a cigarette. The capsule or capsules are provided between first and second absorbent members (32, 34) and the capsules are subjected to an external force, such as a 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 exposing the additive material to the mainstream smoke passing through the filter. The capsules provide a barrier between the additive materials and the other components of the cigarette, such as absorbents or filter materials, So as to reduce a migration of additive material into the other components of the cigarette prior to the intended use. An outer cover 40 which is impermeable to the fluid within the capsules is provided around the capsule or capsules and the first and second absorbent members.
