[0025] "Smoking" a cigarette 10 means heating, burning, or releasing certain chemicals from the tobacco. Generally, smoking a cigarette is a part of the The end is ignited, and the tobacco contained in the cigarette is burned, pyrolyzed, or volatile substances are released. This involves drawing the smoke downstream through the mouth end of the cigarette while it is being distilled. However, cigarettes can also be smoked in other ways. U.S. Patent No. 6,053,176, U.S. Patent No. 5,934,289, U.S. Patent No. No. 5,591,368 or U.S. Pat. No. 5,322,075. By heating the cigarette with a heat source, the cigarette can be smoked. The entire contents of the disclosure are incorporated herein by reference.

[0026] Suitable types of tobacco material that can be used are flue-cured tobacco, burley tobacco, Melilla tobacco, and Indian, Oriental, rare, specialty tobaccos and their blends Tobacco materials include, but are not limited to, tobacco lamina, volume expansion Tobacco or processed tobacco materials such as puffed tobacco, cut rolled tobacco processed tobacco stems, such as cut puff stems, reconstituted tobacco materials and their blades The present invention may be provided in any suitable form, including, but not limited to, tobacco substitutes, renditions, etc. can also be used.

[0027] In traditional cigarette manufacturing, tobacco is usually in the form of cut filters, i.e., approximately 1 / 4 10 inches (2.54 mm) to approximately 1 / 20 inches (1.27 mm) or Further, cut tobacco into widths in the range of about 1 / 40 inch (0.635 mm) or is used in strand form. The length of the strands ranges from about 0.25 inches (6. 35 mm) to about 3.0 inches (76.2 mm). may contain one or more flavoring or other suitable additives (e.g., combustion additives, oxidation modifiers, colorants, The composition may further include an inorganic binder, etc.

[0028] The filter material of the filter 14 may be any of a variety of suitable materials for use in tobacco smoking filter elements. It can be any fibrous material. Typical fibrous materials are cellulose acetate, polyvinyl chloride, ... The absorbent (or filter material) 20, 22, 24, 26 preferably comprises propylene or paper. It may be cetyl cellulose.

[0029] Using a variety of cigarette filter configurations that may incorporate one or more flavoring particles Exemplary filter structures that can be used are mono filters, dual filters, tri filters, and tri-filters. pull filters, single or multiple cavity filters, recessed filters, Free flow filters and combinations thereof. Mono filters typically contain cellulose acetate tow or cellulose paper material. Simple monocellulose or paper filters often provide good retention of tar and nicotine. Dual filters typically have a cellulose acetate mouth end and a pure The dual filter contains a cellulose or acetyl cellulose portion. The length and pressure drop are chosen to provide optimal sorption while maintaining acceptable withdrawal resistance. The triple filter has a mouth section, a smoking material or tobacco section, and a paper-containing center section. The cavity filter may include a small number of filters separated by at least one cavity. It includes at least two parts, for example acetate-acetate, acetate-paper, paper-paper. Recess filters include an open cavity on the mouth side. Contains additional sorbents, catalysts or other additives suitable for use in cigarette filters. It is also possible.

[0030] According to an exemplary embodiment, the filter 14 of the exemplary embodiment of the cigarette 10 is The sorbent, such as activated carbon, may be arranged with the sorbent and downstream flavoring particles. The flavoring particles may be spaced apart from the one or more flavoring particles. The second part or portion of the filter may be spaced apart. The filtering action of cigarettes is achieved by sorbents, and flavors affect the absorption of sorbents. The flavor is distributed in the cigarette without being absorbed into the sorbent or being absorbed into the sorbent. It can be placed.

[0031] As used herein, the term "sorption" refers to filtration and / or absorption by absorption. Sorption involves interactions at the outer surface of the sorbent as well as within the pores and channels of the sorbent. In other words, a "sorbent" is a material that condenses or attracts molecules of other substances onto its surface. or the material that can be retained, and / or the infiltration of, for example, the internal structure of the sorbent or the pores of the sorbent. As used herein, the term "sorbent" refers to a substance that can absorb other substances by permeation. As used herein, the term refers to a material that can perform a function such as absorbent, adsorbent, or both. The term "removing" as used herein refers to the absorption and / or inhalation of at least a portion of the components of mainstream tobacco smoke. Refers to the garment.

[0032] While any suitable material can be used as the sorbent, in a preferred embodiment, activated carbon sorbent is used. The sorbent may comprise a sorbent or porous material that absorbs and / or adsorbs gas components on its surface. Any material that has the ability to absorb or assimilate such ingredients into its body. Optionally, the sorbent may have catalytic materials incorporated therein. The sorbents include carbons such as activated carbon, alumina, silicates, molecular sieves and zeolites. Sorption materials may include, but are not limited to, sorbents that may be used alone or in combination. In a preferred embodiment, the sorbent material is activated carbon.

[0033] Microporous materials (e.g., microporous sorbents) such as activated carbon are used to filter gaseous components from tobacco smoke. The pore sorbents are smaller than about 20 Å (angstroms) in width or diameter. While microporous materials can be effective in filtering tobacco smoke, The microporous material allows the cigarette designer to add volatile flavor components such as menthol. In particular, microsorbents can impede the ability of tobacco to be used by consumers from the time of cigarette manufacture. During this time, the flavor components are absorbed and / or adsorbed, thereby increasing the effectiveness of the flavor components in the cigarette. tends to reduce

[0034] In addition to the reduction in potency of flavor components due to absorption / adsorption by the pore sorbent, flavor components may also be absorbed by the sorbent. When the sorbent absorbs / adsorbs the flavor components, two further challenges arise: According to one embodiment, the flavoring ingredient provides the sorbent with active sites, which allows the sorbent to produce smoke. Sorbents can reduce the ability of the gas phase to remove target components from the Because it strongly absorbs / adsorbs flavor components, it may not be possible to fully release flavor components. Thus, separation between the microporous material and the flavoring ingredients or other additives is desired.

[0035] The term "additive" refers to any material or component that changes the characteristics of a cigarette when the cigarette is smoked. Any suitable additive material or combination of materials may be added to one or more flavoring particles. Such additives can be included to modify the characteristics of the cigarette 10. This includes other smoke modifiers such as chlorine-based additives and chemical reagents such as 3-aminopropylsilyl (APS). Furthermore, the additive may or may not affect the organoleptic qualities of mainstream smoke. A diluent, solvent, or additive that aids in the encapsulation of pharmaceutical and additive processing and in the presentation of cigarettes. Processing aids may also be included.

[0036] In an exemplary embodiment, the additive material is a liquid flavor or solid flavor and flavor formulation or flavor-containing material. The term "flavor" or "tobacco flavor" refers to one or more flavors, such as tobacco flavors, flavorants, and flavorants. The flavoring agent particles are releasably disposed in liquid form within the flavoring agent particles, for example, produced by a cigarette. The composition may comprise any flavour compound or tobacco extract suitable for enhancing the flavour of the mainstream smoke produced.

[0037] Suitable flavors or flavorings include mint, menthol, peppermint, and spearmint. chocolate, licorice, citrus and other fruit flavors, gamma-octalactone, vanilla ethyl vanillin, breath refresher flavor, spice flavor such as cinnamon, salicylic acid Methyl acetate, linalool, bergamot oil, geranium oil, lemon oil, ginger oil and tallow Other suitable flavors include, but are not limited to, baco flavors. Choline, ester, aldehyde, ketone, pyrazine, and combinations thereof or and blends of the above.

[0038] For example, according to an exemplary embodiment, the flavoring particles 50 may comprise from about 1% to about 10% flavor by weight. It may contain flavorings and 99% to 90% wax by weight, more preferably or from about 2% to about 5% by weight of flavoring or flavoring and from 98% to 95% by weight of flavoring or flavoring. For example, according to an exemplary embodiment, the molten wax may include 5% by weight of It contains flavor and 95% by weight wax.

[0039] In one embodiment, the additive may serve as a chemical reagent for one or more components of mainstream smoke. Such additives may, for example, be chemically modified to interact with one or more components of mainstream smoke. Additives may be included. See, for example, commonly assigned U.S. Patent No. 6,209,547, which describes the reagents. See the specification and U.S. Pat. No. 6,595,218, the disclosures of which are both incorporated herein by reference in their entireties. and is hereby expressly incorporated by reference.

[0040] Flavoring particles within the filter structure provide advantages, particularly for cigarettes containing activated carbon. In cigarettes containing activated carbon in the filter, flavoring particles are introduced into the filter downstream of the activated carbon. When placed in the oven, the activated carbon absorbs the released additives, thus deactivating the carbon. Therefore, when the additive is a flavouring ingredient, it is preferable to use a During and after smoking, the activated charcoal is substantially prevented from absorbing flavors.

[0041] By incorporating an additive, such as a solid, vapor or liquid, into one or more flavoring particles within the filter. This can greatly reduce the loss of flavor to sidestream smoke, and the loss of flavor from pyrolysis during smoking of a cigarette. In addition, the filter section contains one or more additives. By positioning the flavoring particles on the smoke, activated carbon removes 1,3-butadiene, acrolein, and other flavorings from mainstream smoke. Altering cigarette smoke, including the ability to remove volatile organic compounds such as isoprene and isoprene It can maintain its capabilities.

[0042] As used herein, the term "releasably disposing" refers to a material that is fully inclusive of the additive, e.g., a retaining agent. The additive is encapsulated in the flavoring particles so as to substantially prevent or minimize unwanted migration into the tube. This term refers to the breaking apart or freeing of flavoring particles by, for example, mechanical forces. The flavoring particles are sufficiently fluid that when opened, the additive material is released from the flavoring particles. For example, flavoring particles may be included in cigarette packs. The flavoring particles are released on demand by mechanical interference, squeezing a portion of the Bacofilter; This in turn allows the additive to be released from within the flavor particles.

[0043] FIG. 2 is a perspective view of a portion of a cigarette filter 14 according to one embodiment. Thus, the filter 14 includes a first absorbent material 22, a second absorbent material 24, and a first absorbent material 22 and a second absorbent material 24.

The material particles or chunks 50 preferably have an irregular shape.

[0045] According to an exemplary embodiment, the primary absorbent member 22 and the secondary absorbent member 24 are made of acetyl cellulose. In a preferred embodiment, the flavoring particles or chunks 50 are disposed within the primary absorbent member 22. and the second absorbent member 24.

[0046] According to an exemplary embodiment, the flavoring particles or chunks 50 are formed into a single or multiple part flavoring particles or chunks. The flavor particles or chunks 50 may be formed in a variety of physical formulations. When providing the flavoring particles, the flavoring particles 50 are provided by dispersing them in the filter portion of the cigarette. or may be provided in one or more cavities 26, 27 within the filter 14. Cut.

[0047] The flavoring particles or chunks 50 of the cigarette 10 are mechanically interposed to the additives on demand. When the flavoring particles are released, the additive material is released from the flavoring particles. From there, the liquid can flow through the secondary absorbent member 24 and then through the primary absorbent member 22. The extraction air flows through a steam set cellulose acetate annular layer 32 or overwrap. The filtration performance of the acetyl cellulose can be adjusted by using a dilution hole, etc. The flavoring particles are absorbed by the activated carbon in the filter 14. The flavoring particles or chunks 50 may be suitable for use with a cigarette containing , which may include flavoring ingredients, and which promote selective filtering of mainstream smoke and may be used prior to smoking of the cigarette 10. It may also include components that are released.

[0048] The size, density and composition of the primary absorbent member 22 and secondary absorbent member 24 can be adjusted to accommodate a variety of dilution needs. Various levels of pressure, flow and resistance to pumping can be achieved.

[0049] To release the encapsulated additives from the flavoring particles or chunks 50, mechanical action or the like may be used. An external force can be applied. One suitable method of applying an external force is before or after smoking the cigarette. The user squeezes or exerts external force on the filter containing the flavoring particles while smoking. Preferably, the flavoring particles 50 are broken up, or broken apart, by the use of a squeezing action or external force. The primary reservoir is at least partially deformed and then mechanically locked in place. This displacement will then displace the encapsulated flavoring particles or inner elements. At least one open space will be created between the inner elements. Some of the flavoring particles 50 can be released and pass through the open space, e.g. The liquid and / or vapor is released from the flavoring particles 50 to modify the tobacco smoke passing through the filter. The direction of the force can be along the cigarette axis or perpendicular to the cigarette axis. The direction of insertion can be set to the direction of insertion. A twisting force can also be applied. Using an external device such as a squeezer, tweezers, or any other device that applies a twisting or compressive force This allows for repeated focusing of forces at a defined filter location.
