Description

Cigareta s redukovanou plynnou fázouCigarette with reduced gas phase

Oblasť technikyTechnical field

Vynález sa týka cigarety podľa význaku hlavného patentového nároku 1.The invention relates to a cigarette according to the feature of the main claim 1.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Je známe, že vkladaním materiálov s veľkým povrchom do filtra, ako napr. aktívneho uhlia, môže byť z dymu zadržaná časť plynných súčastí dymu. Selektívna retencia takého druhu vedie k nežiadúcim chuťovým zmenám a tým k odmietaniu takých výrobkov fajčiarmi. Pokusy kompenzovať tento negatívny sprievodný jav sú veľmi nákladné, komplikované a s intenzívnymi výdajmi, pozri tiež DE 41 05 500.It is known that by inserting large surface materials into a filter, e.g. activated carbon, some of the gaseous components of the smoke may be retained from the smoke. Selective retention of this kind leads to undesirable taste changes and thus to the rejection of such products by smokers. Attempts to compensate for this negative accompanying phenomenon are very costly, complicated and costly, see also DE 41 05 500.

Obvyklé, pre plynnú fázu aktívne filtre, sú vo väčšine komorové filtre, ktoré sa rozdeľujú na tri segmenty a v prostrednej komore obsahujú povrchovo aktívny materiál ako aktívne uhlie, morskú penu, silikagél atď. Tieto systémy sú čo do uskutočnenia veľmi drahé a majú závažnú nevýhodu v tom, že stabilita komory z hľadiska stláčania počas fajčenia je neuspokojujúca. Inými možnosťami riešenia sú konštrukcie dvojitých filtrov, u ktorých je aktívne uhlie v malých množstvách rozptýlené vo filtračnom elemente na strane stĺpca tabaku. Tieto konštrukcie majú iba obmedzenú a pre mnohé možnosti použitia nevyhovujúcu redukciu plynnej fázy. Všetkým známym konštrukciám je spoločná negatívna chuťová zmena, ktorú fajčiar označuje ako uhoľná chuť.Conventional gas phase active filters are in most of the chamber filters which are divided into three segments and contain in the middle chamber a surfactant material such as activated carbon, sea foam, silica gel, etc. These systems are very expensive to implement and have the serious disadvantage that the stability of the chamber in terms of compression during smoking is unsatisfactory. Other possible solutions are double filter designs in which activated carbon is dispersed in small amounts in the filter element on the side of the tobacco column. These constructions have only limited and for many applications unsatisfactory gas phase reduction. All known designs are a common negative taste change, which the smoker refers to as a coal taste.

Zreteľné, ale ešte nie celkom uspokojivé zlepšenie sa ukázalo pri použití hodvábneho papiera obsahujúceho uhlie, ktorý bol zmiešaný s mikrojemne zomletým uhlím (veľkosť zrna < 15 gm).A noticeable but not yet satisfactory improvement has been shown by the use of carbon-containing tissue paper mixed with micronised coal (grain size <15 gm).

Podstata vynálezuSUMMARY OF THE INVENTION

Úlohou vynálezu je vyvinúť cigaretu s filtrom aktívnym pre plynnú fázu, ktorý je veľmi účinný a zároveň vyrobiteľný s priaznivými nákladmi.SUMMARY OF THE INVENTION The object of the invention is to provide a cigarette with a gas-phase filter which is very efficient and at the same time obtainable at a favorable cost.

Na riešenie tejto úlohy slúži význak patentového nároku 1.The feature of claim 1 serves to solve this problem.

Vynález sa teda týka cigarety s filtrom, obsahujúcim vo filtri aktívne uhlie:The invention therefore relates to a cigarette with a filter comprising activated carbon in the filter:

a) so stĺpcom tabaku obklopeným cigaretovým papierom;(a) a column of tobacco surrounded by cigarette paper;

b) s dvojitým filtrom, ktorého časť na strane ku stĺpcu je tvorená hodvábnym papierom obsahujúcim uhlie a(b) a double filter, the column side of which consists of tissue paper containing coal; and

c) s ventilačnou zónou filtra z acetátu celulózy prebiehajúcou v smere obvodu v časti na strane k ústam;(c) a ventilation zone of the cellulose acetate filter extending in the circumferential direction in the mouth-side portion;

d) hodvábny papier časti filtra na strane ku stĺpcu je veľmi voluminózny papier, ktorý obsahuje 20 až 50 hm.% mikrojemne zomletého aktívneho uhlia;(d) the column side tissue paper is a very voluminous paper containing 20 to 50% by weight of micronised activated carbon;

e) pomer kondenzát - retenčné výkony úseku filtra od strany ku stĺpcu do strany k ústam je medzi 1 a 2;(e) the condensate-retention performance ratio of the filter section from side to column to side to mouth is between 1 and 2;

f) priepustnosť vzduchu cigaretovým papierom je 40 až 100 Coresta jednotiek; a(f) the air permeability of the cigarette paper is 40 to 100 Coresta units; and

g) ventilačný stupeň filtra je 5 až 60 %.g) the filter ventilation stage is 5 to 60%.

Výhodné uskutočnenia vynálezu sú predmetmi význakov závislých patentových nárokov.Preferred embodiments of the invention are subject to the features of the dependent claims.

U cigarety s filtrom podľa vynálezu je poréznosť cigaretového papiera 30 až 60 rel % vyššie než poréznosť cigaretového papiera porovnateľnej cigarety vyrobenej s konvenčným filtrom a ventilačný stupeň filtra je 10 až 60 rel. % nižšie než ventilačný stupeň filtra porovnateľnej cigarety vyrobenej s konvenčným filtrom.In a filter cigarette according to the invention, the porosity of the cigarette paper is 30 to 60 rel% higher than the porosity of the cigarette paper of a comparable cigarette made with a conventional filter and the filter ventilation degree is 10 to 60 rel. % lower than the filter ventilation stage of a comparable cigarette manufactured with a conventional filter.

Hodvábny papier má gramáž cca 40 - 60 g/m2, obsah aktívneho uhlia 15 50 % a hrúbku 150 - 200 gm. Výhodný variant má gramáž 50 g/m2 a obsah aktívneho uhlia 30 % pri hrúbke 180 pm.The tissue paper has a weight of about 40 - 60 g / m 2 , an activated carbon content of 15 - 50% and a thickness of 150 - 200 gm. A preferred variant has a grammage of 50 g / m 2 and an activated carbon content of 30% at a thickness of 180 µm.

Vo zvláštnej forme uskutočnenia je úsek filtra na strane stĺpca u dvojitého filtra Core filtrom podľa DE 42 05 658 C2, v ktorom jadro je vytvorené z hodvábneho papiera obsahujúceho uhlie ako vo skôr menovanej forme uskutočnenia, ktorý je obalený plášťom z materiálu takmer nepriepustného pre hlavný prúd dymu. Tento pre dym takmer nepriepustný materiál sa skladá napríklad zo silne stlačených vlákien acetátu celulózy.In a particular embodiment, the column side filter section of the double Core filter is a filter according to DE 42 05 658 C2, wherein the core is formed of a carbon-containing tissue paper as in the aforementioned embodiment, which is wrapped with a sheath of material impermeable to mainstream smoke. This smoke-impermeable material consists, for example, of heavily compressed cellulose acetate fibers.

Prekvapujúcim spôsobom sa ukázalo, že pri vložení materiálu aktívneho pre plynnú fázu majú rozhodujúci vplyv nielen retencia plynnej fázy, ale aj špecifické pomery retencie jednotlivých segmentov filtra v kombinácii s ventilačnými pomermi cigarety. Ako zvlášť priaznivé sa ukázali v tabuľke 1 uvedené kombinácie B, D a F retenčných a ventilačných pomerov. Kombinácie A, C a E sú známe cigarety, ktoré boli kombináciami B, D a F podľa vynálezu zmenené.Surprisingly, it has been shown that not only the gas phase retention but also the specific retention ratios of the individual filter segments in combination with the ventilation ratios of the cigarette have a decisive influence on the insertion of the gas-active material. Combinations B, D and F of the retention and ventilation ratios have been shown to be particularly favorable in Table 1. Combinations A, C and E are known cigarettes that have been altered by Combinations B, D and F of the invention.

Senzorické porovnávania boli uskutočňované porotou expertov a poskytli nasledujúce výsledky: cigarety A a B sa líšia len z hľadiska reaktivity, pričom variant B bol výrazne menej reaktívny, to znamená v preklade pre konzumenta, menej drsný a menej ostrý.Sensory comparisons were conducted by a panel of experts and gave the following results: cigarettes A and B differ only in terms of reactivity, with variant B being significantly less reactive, that is to say, in terms of consumer, less harsh and less sharp.

Cigarety C a D sa v reaktivite líšia rovnakým spôsobom, pričom tabaková aróma variantu D sa prejavila silnejšie.C and D cigarettes differ in the same way in reactivity, with the tobacco flavor of variant D being more pronounced.

K rovnakému výsledku prišli experti tiež pri porovnávaní cigariet E a F. Variant F bol zreteľne menej reaktívny, mal však zvýšenú tabakovú arómu.Experts came to the same result when comparing cigarettes E and F. Variant F was clearly less reactive but had an increased tobacco flavor.

Je nápadné, že retenčný kvocient jednotlivých segmentov filtra je vyšší so znižujúcou sa hodnotou kondenzátu a nikotínu. Na docielenie aspoň rovnakej kvality tabakovej arómy je súčasne nutné zvýšiť poréznosť cigaretového papiera práve porovnávanej cigarety pri súčasnej redukcii ventilácie filtra. Príčinou lepšieho relatívneho nastavenia kvality arómy by tu mohlo byť rozvrstvenie veľkosti častíc v hlavnom prúde dymu, ktoré sú určujúce pre rozdielne rýchlosti prúdenia a tým sú ovplyvňované rozdielne teploty, pri ktorých nastáva tlenie tabaku. Pokusy ukázali, že keď sa k sebe navzájom prispôsobia podľa prúdenia pokusná a porovnávacia cigareta, tak dochádza k tzv. uhoľnej chuti a poklesu na kvalite arómy.It is remarkable that the retention quotient of the individual filter segments is higher with decreasing condensate and nicotine values. At the same time, in order to achieve at least the same quality of tobacco flavor, it is necessary to increase the porosity of the cigarette paper of the currently compared cigarette while reducing filter ventilation. The reason for the better relative adjustment of the aroma quality could here be the stratification of the particle size in the mainstream of the smoke, which determines the different flow rates and thus influences the different temperatures at which tobacco decay occurs. Attempts have shown that when the test and comparative cigarettes adapt to each other according to the flow, so-called &quot; coal taste and decrease in aroma quality.

Na nastavenie požadovaného pomeru retencie úseku filtra od strany ku stĺpcu do strany k ústam môžu byť vedľa známeho acetátového monofiltra použité aj iné formy uskutočnenia: koaxiálna konštrukcia časti filtra pri ústach poskytuje známym spôsobom možnosť nezávisle od seba optimálne nastaviť súčasne požadovanú retenciu a požadovaný otvorený odpor ťahu cigarety.In addition to the known acetate monofilter, other embodiments can be used to adjust the desired retention ratio of the filter section from side to column to side to mouth in addition to the known acetate monofilter: the coaxial design of the mouth filter section provides cigarettes.
