Embodiment Construction

[0022] A filter device is provided with an additive material, such as a flavoring ingredient, in a tobacco product, such as a cigarette. By using one or more capsules, preferably sealed or frangible capsules, comprising the additive material, an improved delivery capability by controlled release of the additive material to the cigarette can be obtained. The use of capsules allows the core of the capsules to be released in a controlled manner by the smoker. This controlled release provided by the capsule can reduce the reaction between the additive material and the cigarette, can reduce the evaporation and migration of the additive material within the cigarette, can allow uniform or non-uniform distribution of the additive material, and / or can control the amount of the additive material. Release to achieve proper timing until a predetermined stimulus occurs, and / or may allow in situ mixing of additive materials.

[0023] The one or more capsules are preferably contained in the...

Abstract

Improved delivery of additive materials to cigarettes is provided through the use of one or more capsules containing additive materials, such as flavor components, in the filter section of a cigarette. The capsule or capsules are provided between first and second absorbent members and 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 fluid within the capsules is provided about the capsule or capsules and the first and second absorbent members.

Description

technical field [0001] The present invention relates to cigarettes and filter subassemblies for cigarettes and methods of making cigarettes and cigarette filters. Background technique [0002] The sorbents incorporated in some conventional cigarettes do not satisfactorily provide the smoker with the desired taste effect. The uniformity of flavored cigarettes was not entirely satisfactory due to the volatility of the added flavor. Accordingly, there is interest in improved devices and methods of supplying additive materials or medicaments, such as flavorants, to cigarettes. Irreversible loss of volatile flavorant may also occur after flavorant migration to sorbents used in cigarette filters to remove target gas phase components. These sorbents also adsorb flavorants supplied in mainstream smoke, thereby reducing the taste and sensory characteristics / acceptability of cigarettes. Contents of the invention [0003] In a first embodiment, the cigarette filter subassembly com...
