Field of technology

The present invention relates to a method of adding or incorporating tobacco flavor into a filter plug wrap, a semi-encapsulated flavor, and the resulting smoking articles and filters. More specifically, the present invention relates to a flavoring method in which some of the flavor remains in the filter wrapper and some of the flavor is transferred to the filter wrapper, cigarette paper, and tobacco, and the resulting smoking article and It is about a filter.

 Flavors and aromas are important properties of smoking articles such as cigarettes. Current methods of incorporating flavor into tobacco include spraying flavor into tobacco, inserting pellets into the filter, inserting a flavor string, injecting flavor into the filter, spraying flavor onto cigarette paper, or flavoring into a cigarette. Inserting a strip is included. Furthermore, certain cigarettes have filter fragments incorporating flavorants.

For example, U.S. Patent Publication No. 2002/0166563, invented by Jupe et al. , Discloses a cigarette by spraying flavoring on a group of activated carbons in a mixing drum or in a fluidized bed containing nitrogen as a fluidizing agent. Teach is added to the carbon in the filter of the flavoring agent, which may then be sprayed onto the carbon in the bed. This carbon is located in a region of the filter. However, carbon often produces undesirable metallic flavors. In addition, carbon often absorbs the flavor of mainstream smoke during smoking. In addition, because of the volatility of some perfumes and fragrances they are often at least partially "lost" during the manufacture, packaging and storage of cigarettes. Therefore, it is often necessary to increase the initial content of flavors and aromas to compensate for the lost flavors and aromas, which is expensive.

Smoking articles containing flavor components suspended in a binder are preferred. Flavors suspended in binders are known in the art. Perhaps the best known example is LISTERINE® ORAL CARE STRIPS, which is a fast dissolving oral consumer film used to deliver flavors such as cinnamon and mint, deodorants, and antibacterial agents. U.S. Pat.No. 6,596,298 to Leung et al. Discloses carboxymethyl cellulose, pullulan, hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, polyvinyl alcohol, Sodium alginate, polyethylene glycol, xanthan gum, tragacanth gum, guar gum, acacia gum, arabic gum, polyacrylic acid, methyl methacrylate copolymer, carboxyvinyl polymer, amylose, high amylose starch, hydride Roxypropylated high amylose starch, dextrin, pectin, chitin, chitosan, levan, elsinan, collagen, gelatin, zein, gluten, soybean isolate, whey isolate protein, casein, and their A fast dissolving oral film containing flavor and antimicrobial agents suspended in a binder selected from the group consisting of mixtures is taught. US Pat. No. 6,656,493 to Dzija et al. And US Pat. No. 6,740,332 to Zyck et al. Provide maltodextrins, fillers (e.g. microcrystalline cellulose (MCC)), and hydrocolloids (e.g. Edible films for oral cleansing and odor removal with sodium alginate) as a film former. However, there is still a need for smoking articles that contain flavoring ingredients that can add flavor to smoking articles that are effective in producing and producing preferred flavors. There is also a need for smoking articles that contain flavor components that are not lost during tobacco production, packaging, and storage.

Summary of the Invention

In view of the known deficiencies with respect to the filter components of conventional smoking articles, there is provided a smoking article containing tobacco additives added to or incorporated into the filter wrap, wherein the filter wrap is carboxymethyl cellulose (hereinafter referred to as "CMC"). Fragrance suspended in a binder such as; Other binders known in the art such as pullulan, hydroxypropylmethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, polyvinyl alcohol, sodium alginate, polyethylene glycol, xanthan gum, tragacanth Gum, guar gum, acacia gum, arabic gum, polyacrylic acid, methyl methacrylate copolymer, carboxyvinyl polymer, amylose, high amylose starch, hydroxypropylated high amylose starch, dextrin, pectin, chitin, chitosan, levan, Elcinane, collagen, gelatin, zein, gluten, soybean isolate protein, whey isolate protein, casein, maltodextrin, fillers (e.g. microcrystalline cellulose (MCC)), hydrocolloids (e.g. sodium alginate), and mixtures thereof This may also be used.

In the present invention, mainstream smoke passes through the carbon-based filter before passing through the flavored filter wrap. As such, flavors such as cinnamon and menthol are not readily absorbed by the carbon-based filter. The present invention also provides a smoking article that is effective in producing a smoking article that produces a desired flavor and a flavored smoking article that will not be reduced during the manufacture, packaging, and storage of a cigarette.

Smoking articles, such as cigarettes, generally comprise a tobacco rod surrounded by a paper wrapper, and a columnar filter arranged coaxially with the tobacco rod. Generally, this filter comprises a cellulose acetate filter plug bonded to the tobacco rod by tipping paper. After igniting the cigarette, the smoker sucks the mainstream smoke from the lit end of the tobacco rod to the upstream end of the filter and then inhales through the downstream (or cheek) end of the cigarette.

The present invention provides a method of constantly supplying a flavourant, wherein the flavourant holds a composition of CMC or any of a variety of other binders as mentioned above, which can suspend the flavor and degrade during the smoking process. It includes a flavor filter paper. In particular CMC is a semisynthetic water soluble polymer wherein CH ₂ COOH groups are substituted on the glucose units of the cellulose chain and generally function as binders, film formers, and suspending agents. The flavor is incorporated into the material used as the filter wrap for the cigarette filter through a method such as encapsulation or suspension, which wraps the cigarette filter concentrically. This filter paper is decomposed by components generated by smoking such as heat and / or water vapor, thereby releasing flavor. Some flavor will remain in the wrapper and some of the flavor will migrate to filter plugs, cigarette paper, and tobacco.

Since the mainstream smoke must pass through the fragrance filter wrap located in the filter, the release of flavor will continue to be maintained during smoking. During smoking, the flavor is transferred to the mainstream smoke of the cigarette and then to the smoker without pyrolysing material. This method is particularly preferred because it is used to bypass certain filter materials through which mainstream smoke passes, so that fragrances such as cinnamic aldehyde can be used, which would normally be captured by a filter material such as carbon. do. Since the flavor is weakened by heat, the fact that the flavor is not heated is desirable. Binders that suspend flavor serve to further protect the flavor from oxidation by heat and air exposure.

The fragrance filter wrapper may possibly wrap the outside of the cigarette filter with the external fragrance filter wrapper and wrap the center of the coaxial filter. Fragrances may range from typical cigarette flavors such as menthol and leaf tobacco flavors to atypical cigarette flavors such as cinnamon.

For a better understanding of the invention, reference is made to the following description in conjunction with the following figures, together with its other and further objects, the scope of the invention being pointed out in the appended claims.

Aspects and advantageous effects of the invention will be better understood upon taking the detailed description of the preferred embodiments in conjunction with the following figures, which are as follows:

This tobacco rod 12 may be wrapped with a conventional cigarette paper 16. This filter 14 comprises a filter plug 11 constrained in the filter wrap 13, such as, for example, a cellulose acetate plug or other fiber or woven material. The tipping paper 18 restrains the filter wrap 13. Mainstream smoke occurs when the smoking article 10 lights and inhales and is sucked from the tobacco rod 12 through the filter 14.

The filter paper 13 is a composition of carboxymethylcellulose (hereinafter referred to as "CMC") or any of a variety of other binders capable of suspending the flavoring agent as described above. Fragrance methods are known in the art. The fragrance filter wrapper 13 filters the portion of the flavor to remain in the filter wrapper 13 and a portion of the flavor to the filter plug 11, tipping paper 18, cigarette paper 16, and tobacco rod 12. It is located around the plug 11. The flavored filter wrap 13 can be flavored during the manufacturing process of the cigarette. The amount of flavored filter wrap 13 per cigarette may vary depending on the size of the flavored filter wrap 13 and the concentration of flavor suspended in the flavored filter wrap 13. When the mainstream smoke is sucked upstream through the filter 14, the flavor continues to be released into the mainstream smoke as the mainstream smoke passes through the filter plug 11 wrapped in the scented filter paper 13.

With reference to FIGS. 3 and 4, embodiments of the invention include a smoking article 30 comprising a rod 32 of smokeable material, such as tobacco, and a filter 34 bonded to the rod 32. This tobacco rod 32 may be wrapped with a conventional cigarette paper 36. The filter 34 comprises a filter plug 31 such as, for example, a cellulose acetate plug or other fiber or woven material, constrained to the first flavored filter wrap 33. The tipping paper 38 constrains the first flavored filter wrap 33. A filter core 37 disposed centrally in the filter plug 31 is constrained by a second, deflected wrap 35.

The first and second flavored filter wrappers 33 and 35 retain part of the flavor in the wrappers 33 and 35, with the majority of the flavor being filter plugs 31, tipping paper 38, and cigarette paper 36. , Tobacco rod 32, and filter core 37 to move. The first and second flavored filter wraps 33, 35 can be flavored during the manufacturing process of tobacco. The amount of flavored filter wrap 33, 35 per cigarette may vary, depending on factors such as the size of the flavored filter wrap 33, 35 and the concentration of flavor suspended in the wrap 33, 35. When the mainstream smoke is sucked upstream through the filter 34, the flavor continues to the mainstream smoke as the mainstream smoke passes through the filter plug 31 with the first and second flavored filter wraps 33, 35. Is released.

Referring to FIG. 5, an embodiment of the present invention provides a smoking article 50 containing a filter 52 bonded to the rod with a rod 52 and a tipping paper 58 of a smokeable substance, such as tobacco. . This tobacco rod 52 may be wrapped with a conventional cigarette paper 56. The filter 54 may be a complex composite filter. 5 shows a filter 54 separated into a carbon-based filter portion 57 and a fiber filter portion 55 such as cellulose acetate or another woven material. The carbon-based filter portion 57 may be constrained with a conventional wrapper 59, while the fiber filter portion 55 may be constrained with a flavored filter wrap 53. The tipping paper 58 constrains both the usual wrapper 59 and the flavored filter wrap 53. Mainstream smoke occurs when the tobacco bar smoking article 50 lights and inhales and is sucked through the filter 54 from the tobacco rod 52.

The flavored filter wrap 53 is positioned around the fiber filter portion 55 such that a portion of the flavor remains in the flavored filter wrap 53 and a portion of the flavor moves to the fiber filter portion 55. When the mainstream smoke is pumped upstream through the filter 54, the smoke first passes through the carbon-based filter portion 57 and then through the fiber filter portion 55, where the flavor is directed through the flavored filter wrap 53. From mainstream smoke. If present, a very small amount of flavor of the phase in the flavored filter wrap 53 is absorbed by the carbon-based filter portion 57. Accordingly, the smoker can receive most of the flavor derived from the flavored filter paper 53.

Mensol fragrance was added to the filter wrap 13 to measure the amount of flavor transferred to the smoke. The approximate weight of material in the flavored filter wrap 13 was 33 mg per 27 mm of filter 14. Due to the loss of menthol flavor during manufacture of the flavored filter wrap 13, virtually 0.58% of menthol was present in the samples used in the experiments. Since 0.58% of the sample was menthol and the weight of the flavored filter wrap 13 was 33 mg, 0.191 mg of menthol was present in the flavored filter wrap 13. Menthol smoke was found to be 0.02 mg per cigarette, thus approximately 10% of menthol was transferred to the smoke in the flavored filter wrap 13.

The foregoing detailed description is provided primarily for clarity of understanding and should not be unnecessarily understood as being limited thereto, and those skilled in the art will appreciate that modifications may be made upon reading this publication and the spirit of the invention and the scope of the appended claims. It will be apparent that modifications will be made without departing from. In this regard, the present invention may be practiced in a wide variety of cigarettes, both narrow and wide.
