Smoking article

The present invention relates to a smoking article with an improved aerosol delivery means for a smoker.

159 793

The term smoking article as used herein includes cigarettes, oygars, pipes and other smoking products that produce aerosols such as smoke. In particular, the subject of the invention is a carbon sheet material, preferably containing tobacco, the sheet being used as at least part of the mouthpiece of such products, in order to transfer flavorings such as ^ θt ^ and <^ l.

Cigarettes, cigars and pipes are the most popular types of smoking products. Over the years, many products and products have been proposed for smoking, stenological improvements or the use of these popular smoking products, and cigarettes. Many smoking materials have been proposed as tobacco substitutes, e.g. in U.S. Patent No. Ammeyki No. 4 079 742 / Telner 1 / This material, called Cytrel 1 ŃSU, was introduced in Europe in the seventies, in the oel of partial replacement of tobacco. However, they have not achieved long-term commercial successes. Many other smoking products, including cigarette type, have been proposed, based on the production of aerosol or steam, e.g. in U.S. Patent No. 4,714,082 / Banerjee et al.

However, in Ladomi, none of the known smoking articles has yet reached other commercial successes and has not been widely introduced. The lack of such products on the market Is, it is believed, caused by many reasons, such as insufficient aerosol ^^^, at the beginning As in the shelf life of the product, poor taste, aftertaste aftertreatment with decomposition tereltznegt smoke generating and / or flavoring agents, the presence of a significant amount of pyrolysis products and smoke emanating from the smoking end of the cigarette, and an ugly appearance.

It is also, despite the decades of interest in 1 significant effort, that there is still no smoking product on the market that provides benefits, benefits and pleasures associated with smoking, without eroding significant amounts of incomplete combustion and pyrolysis.

Recently, however, in European Published Patent Nos. 0 174 645 1 O 212 234 1 in U.S. Patent No. Αμπ 4 4 714 082, assigned to the company 8.J. Reynolds Ttbttot Co., describes smoking articles and a cigarette-type body that provide the benefits, benefits and pleasures of smoking without burning tobacco or producing a significant amount of incomplete combustion or pyrolysis products. The flavoring delivery agents improved according to the invention are particularly suitable for use with these articles.

Menthol smoking articles make up a significant proportion of all products on the market. In fact, almost a third of all cigarettes produced are to some extent eentoltoana. However, one of the main problems associated with menthol and other volatile and semi-fibrous flavors found in smoking articles is the fact that flavoring agents usually migrate to other ingredients. Such migration is documented in iίreraLueze, see e.g. Brozlnski M, and Beitrage zur Tabakforschung International, 6, 124-130 / 1972 /; Curran, JG ,, Tobacco Science 16, 40-42 / 1972 / and neihl. T.i '. et al., Tobacco otlencr 17, lo-li / 1973 /.

Cigarettes migrate regardless of whether flavorings are introduced into the tobacco, into the filter, into the materials, or in the packaging material (e.g., menthol foil). For all these cases, the end result is similar. During storage, as a result of mg ^ r £ ^ (^,] and flavorings throughout the smoking article and its packaging, a uniform itromatized level is formed as a whole. The degree mj ^ rac, ^ and depends,

Among others, from the glare of the vapor an aromatizing substance), its solubility in various product components, environmental conditions including temperature, relative humidity, resistance of various materials / e.g. tobacco, ovinolaola, flluent material, glue, etc. / per M (g.

Mele attempted to solve the problems associated with Mgraoi, but with little success. For example, to reduce fog, various chemical substances have been used, such as chemically bound non-volatile substances / e.g. menthol complexes with beta-cykyodextrin, glycosides, aM.dy and menthol esters ltd./, described e.g. in U.S. Patent Nos. 3,426,011 / Parmeter and In, / 1 3 344 796 / Yamji 1 in./. In general, however, all of these compounds find limited use because of the costs and because of the unfavorable taste sensations of the resulting smoke.

They also tried to use the so-called encapsulated flavors at various locations in the smoking article, oo are described, for example, in U.S. Patent Application No. 3 550 598 1 3 540 456 / Mo Olumphy 1 ff, Swiss No. 475 418 / βaumgartuer Papiers 5.A / 1 Dutch No. 8 201 585 / Dowve Egberts Κο ^ ηϋ ^ β /. Other tests concerned volatile flavoring in polymer systems such as linear polyethylene and non-organic filters, e.g. CaCOg, alumina ltp. 1 these substances are in the form of beads or fibers or particles in filters or in packaging. In these tests, it turned out that migration was still occurring (although in a controlled way), moreover, that large amounts of flavorings were needed, which led to the initial cost, and the overall delivery efficiency of these substances was low, usually 1-18> by weight ^ t ^^ t ^ r ^ ku to the quantities used.

The use of carbon in various components of cigarettes has also been proposed. Particularly used in wrapping systems, as filler material and in filtering systems to reduce gaseous constituents of smoke and to introduce flavoring substances into a cigarette. This is described, for example, in United States Patent Nos. Ammrics No. 2 063 014 / Allen //, 3 744 496 / Ułjćarty 1 lin./, 3 902 5o4 / Owens 1 in./, 4 505 202 / Oogblll i lin / and 4 225 636 / Cllne 1 lin./. However, carbon, and especially activated carbon, has not achieved significant commercial use as a carrier for flavoring agents such as mni (^ 1, because, among other reasons, activated carbon absorbs a greater proportion of menthol before it is delivered with palaozonl. To compensate for this phenomenon, generally saturated carbon materials are μθ .ζζ.... substances, however, as mentioned above, this causes undesirable Mgration to other parts of the smoking article, see e.g. United States Patent No. 3,236,244 / Irby 1 Nov / describes the use of activated carbon to remove unwanted components from smoke as well as to incorporate flavorings into it.

United States Patent No. 3,972,335 / Tigglebeok 1 lu./ discloses blocking of small pores of activated carbon with an agent modifying pores, such as sucrose. This agent is used in such an amount that the retention portions of the activated carbon are not blocked, but remain free for absorption of the aqueous substance. This increases the durability of smoking products during storage by reducing the Mgration of the fragrance, and unanimously enables effective Jwarnlaule during smoking. However, it seems that there is oz ^ γ £ ^ (^,) ι, over 40% / see example 1, columns 5-6 /. As a result, charcoal filters or ovens for smoking articles are generally not recommended.

The subject of the invention is a smoking article comprising a fuel element 10, a physically separated aerosol generating agent 12 containing one aerosol generating substance and a separate agent 24, providing a smoker with an aerosol by means of an aerosol generating agent. the essence of the invention is

159 798 is that the aerosol delivery agent 24 comprises carbon-filled sheet metal with at least one flavoring agent that gives flavor to the palaose-delivered aerosol.

Menthol, for example, can be mentioned as a volatile flavoring substance. This substance is delivered to the aerosol smoker, without significant Mgraojl flavoring to the fuel element or to other components of the smoking article. The improved flavoring agent is a carbon-filled sheet material housed in a non-smoking part of the article for smoking, e.g. in any part of the product mixed along along the fuel element and at a distance from the fuel element. It forms a cylindrical segment or a Mosaic cartridge between the aerosol generating agent and the mouth end of the smoking article.

Incidentally, the smoking article using the perfume delivery agent are cigarettes containing a short, i.e. less than 30 m long, preferably carbon, fuel element. In a co-operating manner, the aerosol generating agent is positioned longitudinally downstream of the fuel element, so that heat exchange by conduction with the fuel element is ensured. The oral cement preferably comprises a filtration segment, preferably with relatively low scouting, so that it does not interfere! In providing the aerosol produced by the aerosol generating agent, the flavoring agent according to the invention is a carbon-filled sheet that can be used in any non-burning component of a smoking article, i.e. in any unit located along the back or away from the fuel element. Preferably, it is sandwiched between the flute segment and an aerosol generating agent, and in some preferred embodiments, the flavoring subsection supplying agent is a segment of rolled, folded or crumpled sheets of carbon, made of tobacco paper, about 5-15 mu m long.

It has been found that the improved flavoring agent according to the invention helps to place Mgrao flavoring substances, in particular, other volatile flavoring compounds, to other components of the smoking article or to the equipment used to manufacture these articles. The depletion of Mg ^ ^ and ^,) and to the fuel source is particularly important due to the undesirable aftertaste that may arise as a result of the decomposition of thermiose and the pyrolysis of flavorings peeled in the burning fuel element. This grain of Mgracjl also helps to extend the storage life of smoking articles containing volatile aromatizing substances such as roluole. It has also been found that flavoring substances are easily released 1 eq. Not when smoked from a sheet Mttrl. Carbon filled with an aerosol and that hot gases from the aerosol generating agent pass over or through the sheet material.

It is believed that a slightly higher temperature than the aerosol temperature, about 150 ° C, immediately after the aerosol generating agent helps to deliver even amounts of flavoring substances throughout the lifetime of the smoking article. In addition, smoking articles using carbon sheet material as a component of the mouthpiece provide such a reduction in Mgraoja and uniform delivery of flavors without significantly reducing the delivery of other aerosol components, e.g. glycerol, top water. in other words, the effectiveness of Paving carbon-filled sheet material is much lower than others used in cigarettes as filters, such as a cellulose acetate cartridge. This is important in maintaining the desired level of aerosol delivery in smoking snobs according to the snalaz.

The preferred carbon-filled sheet material according to the invention also acts as a heat transfer substance that helps to lower the temperature of the aerosol entering the palaosis and helps to prevent unwanted decomposition or fusion of the filter material.

Preferred smoking articles using the improved flavoring agent according to the invention are able to provide at least 8, 6 mg of aerosol, hydrated as wet total fine particle / WTPfM, in the first 3 strokes when smoking under FTC smoking conditions. preferred postaols of the invention provide an average of at least about U, 8 mg WfPM per footstroke in at least about 6 strokes, preferably within at least 1 stroke, under FTC smoking conditions.

In addition to the above-mentioned advantages, the correlated smoking articles of the invention are able to provide an aerosol which has a simple chemical composition and consists essentially of carbon air, water, an aerosol-forming substance, any desired flavoring or other volatile substances and trace amounts of other substances. The aerosol preferably does not have significant mutagenic activity measured by the Ames test. In addition, co-sustained articles can be essentially ashless so that the user does not have to shake off ash during smoking.

Used in this description only for ce ^ i ^ in this application, the term aerosol defines it in that it contains vapors, gases, particles, etc., both visible and invisible, especially those components that are felt by the user as generated by the heat interaction of the incinerating clay element on the substances contained in the aerosol generating means or anywhere in the article.

The term compound providing conduction heat exchange as used herein means the physical thickening of the fuel element aerosol generating means by which the oil is transferred by conduction from the burning fuel element to the aerosol generating agent essentially during the burning period of the fuel element. The compound ensuring the heat release by conduction can be achieved by placing the aerosol retaining agent in contact with the paling element, and thus in 0 ^^. 3Ζ ^> approaching the burning part of finger element 1 / or by using a conductive element to transfer heat from the burning fuel to the aerosol generating means. Both methods are used to ensure heat transfer by conduction.

No, the term carbon used in the description means a material containing primarily carbon. As used in the description, the term insulating element refers to all food products that act primarily as thermo-soles when used in smoking articles according to the invention. Correspondingly, these materials do not burn during use, but may contain other flame retardant coals and the like (^^ θηβίν, as well as substances that melt during use, such as iiskosempsraturows, fiberglass grades, appropriate toolators ⁱⁿyka'zuj^and ^ that ^ oiling^pln^and w g-cai / sek / omw ^ C / cia 'mn^andθ^jsy^and than about d, C5, preferably less than about t, 02, most preferably less than about ^ύ,ϋυ5.

The improved flavoring agent according to the invention is intended for use in smoking articles, in particular in smoking articles comprising a combustible fuel element, a physically separated aerosol generating agent and a separate mouthpiece such as described in European Patent Publication Nos. 174 cited above. 645 1 212 234.

Generally speaking, the improved flavoring agent is a sheet material filled with carbon, which is prepared by adding carbon (activated, not activated or a mixture) to ordinary pulp such as papermaking or flax fibers 1 or garnetted stems or pnle. This material is then formed into sheets using conventional stationery paper.

The porosity of the carbon-filled sheet material can vary widely; preferably a specific porosity of between about 100 and 250 CUKESTA Units, and an absolute porosity / net porous above or above about 150 CUHESTA, preferably 30 ° C 30 ° CtloESSA. Absolute porosity is obtained by making holes by mechanical, electrostatic or service methods l / uub by cutting sheet material. Sheeting muddy porosity in this respect is in particular advantageous because it allows the introduction of larger amounts of aromatizing material sheet filled with carbon by means of absorption and / or absorption, because it is possible to increase the total surface area of ​​the delivery medium without increasing the filtering capacity of the filter.

The carbon content of the sheet material can vary widely depending on many factors, such as Jtk type and quantity of carbon 1 / or flavoring substances used, location of the sheet material filled with carbon in the smoking article 1 shape or configuration of the sheet material, ha total content carbon may range from about 5-75> by weight of sheet material, preferably about 10-40 and especially about 15-30 and *. Although higher amounts of carbon can be used, sheets containing more than about 75 wt.% Of carbon cause a reduction in their range, as well as limited paper characteristics, e.g. tensile strength, excessive dusting, ltp.

Although both activated cfu and non-activated carbon can be used as the carbon component of the sheet material, activated carbon is more preferred. As known to those skilled in the art, there are many commercially available activated carbons; they can all be used in the present invention, e.g. activated carbon derived from fossil carbon, wood and coconut shells are available from sources. Activated carbon made from coconut shells, produced under the name PCd by Ctlgon Carbon Corporation, Pittsburg, Pennsylvania is particularly preferred. This grade can be powdered into powders of various zidrna sizes, Although almost all grain sizes can be used for the sheet material according to the invention, the most preferred range is 250,600 US mesh.

Sheet material can contain what is understood by a skilled person,

Other adsorbent / aboriginal materials instead of or simultaneously with the carbon component of this sheet material.

These materials include carbohydrates of animal or other origin, silica gel, zeolites, perlite, sepiolite, activated alumina, magnesium silicates, etc.

As already mentioned, the carbon sheet material can be made from ordinary paper pulp. Preferably, it is made^go Mashani^ny wood pulp and pulp from stalks or ^ptobacco. Carbon component of sheet material^dis usually done ^dabout sludge from fragmented hunts, from which it then forms a sheet in normal a^ppaper nature. An easy sheet material is^ptobacco filler ⁱⁿcoal, obtained by introducing the specified amount of carbon E mass^s paper mill^cthat^j uz^sof tobacco used for the manufacture of ^ptobacco apier ^pfrom the name P144-185-GAPF, produced by Emberly-ClarE Codified paper P¹44-¹85GAPF contains about 60% tobacco, ^gmainly in the form of tobacco stems flavored with light leaf smoke and 35% soft smoke ^pwood slag / percentages for dry mass^s Mteriałów /. The moisture content of unmodified sheet-type material is typically around 1.1% and 14% · This material has a dry tensile strength of approximately 0.6 3 -¹, 29 g / cm, and weight in terms of E dry Ms^s is about 38-44 p

For a professional ^bę^dStill other methods for applying flavorings to carbon are understood, either before or after introduction ^go to sheet material. In practice, the use of an evolving amount of flavorings such as menthol, vanillin, artificial coffee, tobacco extracts, niEtin, and nicotine roles can be used^s, E^fEin, alcoholic beverages, cocoa rounds and other agents that impart odor to the aerosol produced by smoking articles.

159 798

Other flavoring agents that can be used are listed in Leffingwell et al., Totocco Flavorings for Smoking Producta, RJ Reynolds Tobacco Company, Winston-Salem, North Carolina / 1972 /.

The amount of flavoring that has been saturated or elevated per sheet material can vary widely, in ^fromależności ^fromtype of flavoring substance,^d the load of the flavoring substance, from the carbon content in Mtei - sheet metal, from the carbon content, from the Place of placing in the product ^dabout ^pAlenia, from p^pthe person in which the sheet material is^pit is rolled up, folded, wrinkled or otherwise placed in the product ^palenia etc. E.g. if a strong flavoring agent such as alpha-ionone is used, it may be beneficial ^wouldusing as small quantities as 0.00001% by weight^gof these sheet materials. When using mntol, this amount can range from 0.001% to saturation. In preferred burners such as Fr.^pIsano in ^pgovernment^slays down, I have the menthol introduced into the sheet material filled this hose^glem is about 3-6%^, and reading 4-5%.

^Jas mentioned ^pabove, in some tough forms, the carbon-sheet material is placed between the aerosol generating means and the mouthpiece filter and currently has the equivalent of a total filter cartridge. The sheet material can be formed into a total of c^slindric or any other suitable, ^kby conventional methods used to make filter cartridges such as conventional devices for producing cellulose acetate cartridges.

Fig. 3 illustrates one of the devices for forming sheet material filled with a hose^gto the shape of the filter cartridge. ^JAs shown schematically in Fig. 3, a roll of flavored sheet 53 develops ^material filled with serpent^g5 ° and pulls into a tapering taper 54 that wrinkles or folds.

This cylindrical end taz rod is then cut into 57 pieces^phe aid^and cutter ⁵⁸.

Alternatively, the use of the double cone system shown on ^Fg. 3A is not the only cone 54. this system is siloed as a pre-forming device. Carbon sheet material is introduced into the^pring space between the cones in a state of essentially tiez stresses such as ^pat the entrance; sheet material wraps around^pthe annular part of the inner cone. Cones can^and himself ^pshifting relative to each other to obtain uniformity and strength of the cylindrical segment.

Although not jeet, s^pthe basic raw material for good cylindrical knocks^ssegments of aromatized carbon-filled sheet material.

159 798 flavorings are added to the sheet material before forming from the Rego cylindrical segment. Two such p^pmachining people, thalustrovians r.3 Fig. 3, may include a pair of rollers with grooves 59 »used for this crease and a liquid applicator 60 used for surface treatment of sheet material e.g. menthol, ^glccerine or other flavoring or wetting substances.

In preferred embodiments of the invention in which the sheet material filled with^gI am located between the aerosol and the filter at the end of the cigarette from the mouth, in the form of a cylindrical segment or cartridge, the length of the flavored^gof carbon sheet-filled material zMenia changes, generally in dependence on^d type and amount of flavoring used. Sla cigarettes containing tarz^sthe mouthpiece taure described below in^kebaborder of 1 se^gment of sheet material filled with^gLem is generally about ⁵~ 3O mm, a ^korz^sabout ⁵~ 15 rnn, and especially oto ¹⁰ mm.

For reasons of efficiency and / or aesthetics, the content of the flavored aegrant from the carbon-filled sheets of the invention can vary widely, which generally does not affect aerosol delivery.^footkownikowi. ^Jedr. also, it is subject to the use of such se^gwhich give rise to compactness and have a compactness such as cigarettes using tanqualent cetalose acetate filters.

For example, carbon sheet material can ^wouldshredded and included as a whole or as part of a tobacco pipe or maybe ^wouldUsed as one or more non-flammable wrapper, used to combine various parts of a smoking article.

^pWhen the above cigarette is lit, the vaporous element is burned to produce heat that causes the escape of the tobacco aroma substance and various tadasic aerosol forming substances or substances in the aerosol generating taiwan and tobacco tube. ^pbecause root^sanother element; The relatively long palette is a hot, burning fire cone, which is always found in the aerosol producing cup, which maximizes the heat transfer. aerosol-forming taodka and tobacco coil and aerosol protection¹ tobacco flavors, especially ^when root is used^sHeat transfer elements · Hot ^guntil^s, the aerosol and flavors from the aerosol generating taoda and from the tobacco roll heat the flavored carbon-filled sheet material according to the invention, which releases the flavoring substance from it.

This, in turn, increases the temperature at which the flavored carbon-filled sheet material is exposed, which is believed to enhance the release of the flavoring substance from the carbon alclader in the sheet. However, because the aerosol generating substances¹ tobacco flavor and flavoring substance on sheet material^pan eagle^glem p^and physically separated from the item ^paliwowe^goh bad^gthey operate at much lower temperatures ⁿthat these are formed during combustion of fuels, thus minimizing the possibility of thermal degradation of the aroma substance^saerosol forming and forming.
