Abstract
Description
Foreliggende oppfinnelse angår røykeartikler slike som sigaretter, sigarer og sigarillos, og gjelder reduksjonen av sidestrømsrøyk fra røykeartikler. Sidestrømsrøyk er den som fremkommer når artikkelen er tent, men ikke trukket inn av røykeren. Hovedstrømsrøyken er den som genereres når røykeartikkelen trekkes inn av røykeren; kjemien til hovedstrøms- og sidestrømsrøykene er forskjellige. The present invention relates to smoking articles such as cigarettes, cigars and cigarillos, and concerns the reduction of sidestream smoke from smoking articles. Sidestream smoke is that which appears when the article is lit, but not inhaled by the smoker. The mainstream smoke is that generated when the smoking article is inhaled by the smoker; the chemistry of the mainstream and sidestream fumes are different.
Sidestrømsrøyk oppfattes som sjenerende for ikke-røykeren, særlig når en sigarett blir liggende for eksempel på et askebeger, og en eventuell reduksjon av denne er ønskelig. Modifikasjon av hovedstrømsrøyken påvirker oppfatningen av artikkelen av røykeren. Sidestream smoke is perceived as embarrassing for the non-smoker, especially when a cigarette is left, for example, on an ashtray, and a possible reduction of this is desirable. Modification of the mainstream smoke affects the perception of the article by the smoker.
Den foreliggende oppfinnelsen anvender aktivt kull for å modifisere røyken til en røykeartikkel. Selvfølgelig har aktivt kull blitt anvendt i røykeartikler, dog for forskjellige formål, helt siden dets svært gode absorbentegenskaper ble kjent. The present invention uses activated charcoal to modify the smoke into a smoking article. Of course, activated charcoal has been used in smoking articles, albeit for different purposes, ever since its excellent absorbent properties were known.
For eksempel har effektene av forskjellige karboninnhold til filteret blitt undersøkt av Williams et al. i en rapport presentert på den 5. "General Assembly of CORESTA" Wien, oktober 1964, og trykt en gang til i "Beitrage zur Tabaksforschung" volum 3, del 3, side 233-242. Denne viste varierende adsorbans av forskjellige bestanddeler av hovedstrømsrøyken ved forskjellige filterremser av forskjellig make-up. Imidlertid er vårt anliggende å plassere karbon i tobakkssylinderen; dvs. hvor den utsettes for betingelser svært forskjellige fra de som gjelder for et filter. For example, the effects of different carbon contents of the filter have been investigated by Williams et al. in a report presented at the 5th "General Assembly of CORESTA" Vienna, October 1964, and reprinted in "Beitrage zur Tabaksforschung" volume 3, part 3, pages 233-242. This showed varying adsorptivity of different constituents of the mainstream smoke at different filter strips of different make-up. However, our concern is to place carbon in the tobacco cylinder; ie where it is subjected to conditions very different from those applicable to a filter.
GB-A-1512352 viser anvendelsen av aktiverte porøse partikler av karbon festet på tobakk i tobakkssylinderen for å påvirke hovedstrømsrøyken. GB-A-1348580 viser et blad av rekonstituert tobakksmateriale som inneholder aktivt kull anvendt som et hovedmateriale for fremstilling av sigaretter som ga en reduksjon i partikler og nikotin i hovedstrømsrøyken. GB-A-1512352 discloses the use of activated porous particles of carbon attached to tobacco in the tobacco cylinder to affect the mainstream smoke. GB-A-1348580 discloses a sheet of reconstituted tobacco material containing activated carbon used as a main material for the manufacture of cigarettes which provided a reduction in particulate matter and nicotine in mainstream smoke.
Så langt vi er kjent med per i dag, er den eneste beskrivelsen av anvendelse av karbon i tobakkssylinderen med sikte på å redusere sidestrømsrøyk i US-A-5092353 (EP-A-378774). Imidlertid er siktemålet i denne beskrivelsen å redusere sidestrømsrøyken ved anvendelse av innpakningspapir med veldig lav permeabilitet (< 10 CORESTA enheter). For å kompensere for tendensen til selvslukking som dette vil forårsake for sigaretten, var pyrolysert alfa-cellulose til stede i tobakkssylinderen. As far as we are aware as of today, the only description of the use of carbon in the tobacco cylinder for the purpose of reducing sidestream smoke is in US-A-5092353 (EP-A-378774). However, the aim of this specification is to reduce sidestream smoke by using wrapping paper with very low permeability (< 10 CORESTA units). To compensate for the self-extinguishing tendency this would cause to the cigarette, pyrolyzed alpha-cellulose was present in the tobacco cylinder.
Dette pyrolyserte materialet var ikke gjenstand for noen aktiveringsbehandling. Ingen bemerkning er gjort når det gjelder eventuell kjemisk effekt det vil ha på røyken, og det har trolig liten eller ingen effekt, fordi i det spesifikke eksemplet var det pyrolyserte materiale bomullslinters, som vil gi karbon med relativt lavt overflateareal. This pyrolyzed material was not subject to any activation treatment. No comment has been made regarding any chemical effect it will have on the smoke, and it probably has little or no effect, because in the specific example the pyrolysed material was cotton linters, which will give carbon with a relatively low surface area.
GB 1348580 omhandler et røykemateriale som omfatter rekonstituert tobakk, inneholdende aktivt karbon, anvendt som hovedmateriale i produksjonen av sigaretter som gir en reduksjon i partikulater og nikotin i hovedstrøm røyken. GB 1348580 deals with a smoking material comprising reconstituted tobacco, containing active carbon, used as the main material in the production of cigarettes which provides a reduction in particulate matter and nicotine in the mainstream smoke.
Et første aspekt ved foreliggende oppfinnelse vedrører en røykeartikkel som har en tobakkssylinder, kjennetegnet ved at den innbefatter blanding av strimlet tobakk og strimlede rekonstituerte tobakksblader, hvor de rekonstituerte tobakksbladene inneholder partikler av aktivt kull, og en innpakning rundt tobakkssylinderen, hvor innpakningen har en iboende permeabilitet på 20 CORESTA eller større. A first aspect of the present invention relates to a smoking article having a tobacco cylinder, characterized in that it includes a mixture of shredded tobacco and shredded reconstituted tobacco leaves, where the reconstituted tobacco leaves contain particles of activated carbon, and a wrapper around the tobacco cylinder, where the wrapper has an inherent permeability of 20 CORESTA or greater.
I en foretrukket utførelsesform er partiklene av aktivt kull av vegetabilsk opprinnelse, slik som kokosnøtt, idet disse vil inneholde små spor av metaller, som vil hjelpe til med den faste adsorpsjonen av (særlig) aldehyder fra røyken og faktisk også kan danne chelat med slike forbindelser. Fjerning av disse forbindelsene er særlig kritisk for å forbedre opplevelsen av mildhet ved artikkelen når den røykes. In a preferred embodiment, the particles of activated carbon are of vegetable origin, such as coconut, as these will contain small traces of metals, which will help with the solid adsorption of (especially) aldehydes from the smoke and can actually also form chelates with such compounds . Removal of these compounds is particularly critical to improving the mildness experience of the article when smoked.
Samtidig vil det aktive kullet ikke redusere og kan til og med øke visse fordelaktige flyktige komponenter i røyken. At the same time, the activated charcoal will not reduce and may even increase certain beneficial volatile components in the smoke.
Det er videre foretrukket at karbonpartiklene har en gjennomsnittlig partikkelstørrelse på ca. 37 um. It is further preferred that the carbon particles have an average particle size of approx. 37 um.
Nevnte innpakning har en iboende permeabilitet på 20 CORESTA eller større, slik som for eksempel 25 CORESTA, 50 CORESTA, 80 CORESTA eller 180 CORESTA. Said wrapping has an inherent permeability of 20 CORESTA or greater, such as for example 25 CORESTA, 50 CORESTA, 80 CORESTA or 180 CORESTA.
Et andre aspekt ved foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av en røykeartikkel med redusert sidestrømsrøyk og økt opplevd mildhet ved røyking, kjennetegnet ved at strimlet tobakk og strimlede rekonstituerte tobakksblader som inneholder partikler av aktivt kull anvendes som tobakkssylinderen til artikkelen, og et materiale som har en iboende permeabilitet på 20 CORESTA eller større anvendes som innpakning for røykeartikkelen. A second aspect of the present invention relates to a method for producing a smoking article with reduced sidestream smoke and increased perceived mildness when smoking, characterized in that shredded tobacco and shredded reconstituted tobacco leaves containing particles of activated carbon are used as the tobacco cylinder of the article, and a material which has an inherent permeability of 20 CORESTA or greater is used as a wrapper for the smoking article.
Nevnte andre aspekt ved oppfinnelsen inkluderer håndrulling av røykeartikkelen, og foretrukket omfatter den reduksjon i aldehydinnholdet av hovedstrømsrøyken. Said second aspect of the invention includes hand-rolling the smoking article, and preferably includes reduction in the aldehyde content of the mainstream smoke.
Et tredje aspekt ved oppfinnelsen vedrører et kit for håndrulling av en røykeartikkel med redusert sidestrømsrøyk og økt opplevd mildhet ved røyking, kjennetegnet ved at strimlet tobakk og strimlede rekonstituerte tobakksblader som inneholder partikler av aktivt kull anvendes som tobakkssylinderen til artikkelen, og et materiale som har en iboende permeabilitet på 20 CORESTA eller større anvendes som innpakning for røykeartikkelen. A third aspect of the invention relates to a kit for hand-rolling a smoking article with reduced sidestream smoke and increased perceived mildness when smoking, characterized in that shredded tobacco and shredded reconstituted tobacco leaves containing particles of activated carbon are used as the tobacco cylinder of the article, and a material having a inherent permeability of 20 CORESTA or greater is used as packaging for the smoking article.
Det er viktig å være klar over at idet røykeartikkelen røykes, blir røykekomponenter som adsorberes av partiklene minimalt, hvis i det hele tatt, fortrengt fra disse partiklene. De ødelegges av oksider i gassform sammen med materialet til karbonpartikkelen i seg selv ved de ekstremt høye temperaturene (som når opp til ca. 800°C) generert i kullet. It is important to realize that as the smoking article is smoked, smoke components adsorbed by the particles are minimally, if at all, displaced from those particles. They are destroyed by gaseous oxides together with the material of the carbon particle itself at the extremely high temperatures (which reach up to about 800°C) generated in the coal.
Rekonstituerte tobakksblader som inneholder partikler av aktivt kull kan fremstilles ved vanlige teknikker for fremstilling av slike blader, som i sin tur ligner vanlige papirfremstillingsteknikker, hvor bladet deretter blir strimlet for inkorporering med strimlet tobakk som vil være materialet til tobakkssylinderen. Reconstituted tobacco leaves containing particles of activated carbon can be prepared by conventional techniques for the manufacture of such leaves, which in turn resemble conventional papermaking techniques, where the leaf is then shredded for incorporation with shredded tobacco which will be the material for the tobacco cylinder.
En viktig anvendelse av den foreliggende oppfinnelsen vil imidlertid være i "rull din egen" tobakksblandinger, dvs. de som selges løse og som pakkes inn i sigarettpapir av røykeren. However, an important application of the present invention will be in "roll your own" tobacco blends, ie those sold loose and wrapped in cigarette paper by the smoker.
Håndteringen av bladet, om det er ved strimling eller senere manipulering enten i en maskin eller av røykeren, kan forårsake tap av karbonpartikler og det rekonstituerte tobakksbladet kan bli belagt eller limt for å bidra til retensjon av partiklene i det, og særlig partiklene kan i seg selv bli mikroinnkapslet før inkorporering. Dette sistnevnte har fordelen ved å øke størrelsen på partiklene og derfor deres retensjon mekanisk og deres enhetlige størrelse, men, kanskje overraskende, påvirker ikke deres aktivitet. The handling of the leaf, whether by shredding or subsequent manipulation either in a machine or by the smoker, can cause the loss of carbon particles and the reconstituted tobacco leaf can be coated or glued to help retain the particles in it, and in particular the particles can even be microencapsulated before incorporation. This latter has the advantage of increasing the size of the particles and therefore their mechanical retention and their uniform size, but, perhaps surprisingly, does not affect their activity.
Eksempel 1 Example 1
Sigaretter ble fremstilt fra en blanding av "US flue-cured and Burley" tobakk, kuttet rullet stengel og ekspandert tobakk, behandlet og kuttet til 32 kutt per tomme ("cpi"). Inkorporert i den strimlede tobakken var 20% av det rekonstituerte tobakksarket likt kuttet og inneholdende 30% partikler av aktivt kull fra kokosnøtt, med midlere partikkelstørrelse 37 um og som varierte i partikkelstørrelse fra 0,5 um til 150 um. Kontrollsigaretter ble fremstilt identisk, men uten partikler av aktivt kull. Cigarettes were made from a blend of "US flue-cured and Burley" tobacco, cut rolled stem and expanded tobacco, cured and cut to 32 cuts per inch ("cpi"). Incorporated into the shredded tobacco was 20% of the reconstituted tobacco sheet as cut and containing 30% activated carbon particles from coconut, with an average particle size of 37 µm and varying in particle size from 0.5 µm to 150 µm. Control cigarettes were manufactured identically, but without activated charcoal particles.
Sigarettene var 84 mm lange, 7,9 mm i diameter og uten filter. Innpakningen var et 80 CORESTA flaks-basert papir, med 2% kaliumsitrat brannfremmer. The cigarettes were 84 mm long, 7.9 mm in diameter and without a filter. The wrapper was an 80 CORESTA flak-based paper, with 2% potassium citrate flame retardant.
Sigarettene ble gjenstand for røyking på en standard røykemaskin og hovedstrømsrøyken ble analysert i gassfasen og innholdet av delvis flyktige komponenter med resultatene vist i tabellene 1 og 2. The cigarettes were smoked on a standard smoking machine and the mainstream smoke was analyzed for gas phase and semi-volatile component content with the results shown in Tables 1 and 2.
Som det fremgår av Tabell 1, var det en slående reduksjon, selektiv i karakter, av visse aldehyder og ketoner og særlig av akrolein og butyraldehyder, hvor fjerning av disse er viktige for å oppnå en mild smak. På den annen side var det en reell økning sammenlignet med standarden når det gjaldt visse ingredienser, og særlig limonen, som anses fordelaktig for smaken. As can be seen from Table 1, there was a striking reduction, selective in character, of certain aldehydes and ketones and particularly of acrolein and butyraldehydes, the removal of which is important to achieve a mild taste. On the other hand, there was a real increase compared to the standard when it came to certain ingredients, and in particular limonene, which is considered beneficial to the taste.
En lignende reduksjon selv om den var mindre selektiv ble observert av de delvis flyktige forbindelsene som vist i Tabell 2. A similar reduction although less selective was observed for the partially volatile compounds as shown in Table 2.
Eksempel 2 Example 2
Sigaretter og kontroller ble fremstilt ved anvendelse av samme tobakksblanding og Cigarettes and controls were made using the same tobacco blend and
rekonstituerte tobakksark som i Eksempel 1, men ved anvendelse av papir med 25, 50, 80 og 180 CORESTA enheter porøsitet. Sidestrømsrøyken fra de undersøkte sigarettene og fra kontrollene hadde signifikante reduksjoner både i delvis flyktige forbindelser og i niktotininnhold, som det fremgår av Tabell 3. Økt karbonmonoksid- og karbondioksid-produksjon antas å være på grunn av tilstedeværelsen av det partikulære karbonet i tobakksbladet. reconstituted tobacco sheets as in Example 1, but using paper with 25, 50, 80 and 180 CORESTA units of porosity. The sidestream smoke from the examined cigarettes and from the controls had significant reductions both in partially volatile compounds and in nicotinic content, as can be seen in Table 3. Increased carbon monoxide and carbon dioxide production is believed to be due to the presence of the particulate carbon in the tobacco leaf.
