Ventilovaná cigareta s filtromVentilated cigarette with filter
Oblasť technikyTechnical field
Vynález sa týka ventilovanej cigarety s filtrom podľa predvýznakovej časti patentového nároku 1.The invention relates to a ventilated filter cigarette according to the preamble of claim 1.
Doterajší stav technikyBACKGROUND OF THE INVENTION
V spise EP 0 875 160 Al je opísaná ventilovaná cigareta s filtrom, ktorá má časť filtra, ktorá zahrnuje koaxiálne jadro filtra a plášť filtra, obklopujúci koaxiálne jadro filtra. V oblasti koaxiálnej časti filtra sú vytvorené ventilačné otvory na prívod ventilačného vzduchu do plášťa. Vykonanie špecifikácií materiálu a dimenzovania jednotlivých prvkov tabakového povrazca, rovnako tak aj filtra, sú dimenzované tak, že vtedy, keď fajčiar ventilačné otvory zakryje, vedie sa dym na spôsob prepínacieho ventilu v podstate cez plášť filtra, zatiaľ čo u nezakrytých ventilačných otvorov prúdi dym hlavne cez jadro filtra koaxiálnej časti filtra. Cieľ tohto vybavenia je teda taký, že sa môže pri rôznom chovaní konzumentov kvantitatívne riadiť výťažnosť dymu, napríklad sa minimalizuje zvýšenie kondenzačných hodnôt.EP 0 875 160 A1 discloses a ventilated filter cigarette having a filter portion that includes a coaxial filter core and a filter housing surrounding the coaxial filter core. Ventilation openings are provided in the region of the coaxial part of the filter for supplying ventilation air to the housing. Execution of material specifications and sizing of the individual elements of the tobacco rod, as well as the filter, are designed such that when the smoker obstructs the ventilation openings, smoke is guided substantially through the filter housing in the manner of a changeover valve, through the filter core of the coaxial portion of the filter. The aim of this equipment is, therefore, that the yield of the smoke can be quantitatively controlled by varying consumer behavior, for example by minimizing the increase in condensation values.
Tento dym je, videné fyzikálne, aerosól, teda zmes zo vzduchu a kvapiek kvapaliny. Tie môžu byť výrazne rôznej veľkosti, čo ale nie je pre ľudské oko rozpoznateľné.This smoke is, seen physically, an aerosol, i.e. a mixture of air and liquid droplets. These may be of significantly different sizes, but this is not recognizable to the human eye.
Chuťové hodnotenie tabakového dymu konzumentom, teda kvalita arómy, poprípade intenzita chuťového vnemu, je ovplyvňovaná rýchlosťou prúdenia dymu a veľkosťou kvapiek a ich rozptyľovaním, ktoré môžu byť zmerané mobilnými analyzátormi alebo selektívnym zberom a triedením podľa hmotnosti častíc alebo ich veľkosti.The taste rating of the tobacco smoke by the consumer, i.e. the aroma quality or the flavor intensity, is influenced by the flow rate of the smoke and the droplet size and dispersion, which can be measured by mobile analyzers or by selective collection and sorting by particle weight or particle size.
Úloha vynálezu spočíva vo vytvorení konštrukcie filtra, s ktorou sú rozptyľované veľkosti kvapiek, privádzané ku fajčiarovi, a rýchlosť prúdenia dymu riaditeľné.SUMMARY OF THE INVENTION The object of the present invention is to provide a filter structure with which the droplet sizes distributed to the smoker and the smoke flow rate are controllable.
Podstata vynálezuSUMMARY OF THE INVENTION
Na riešenie tejto úlohy slúži cigareta s filtrom so znakmi patentového nároku 1.A filter cigarette having the features of claim 1 serves to solve this problem.
Ak je povrch jadra v časti filtra zo strany úst nepriepustné obalený, alebo je nepriepustné zhotovený, môže byť zabraňované priečnemu prúdeniu hlavného prúdu dymu.If the surface of the core in the filter side portion is imperviously wrapped or made impermeable, the transverse flow of the mainstream smoke may be prevented.
Tým sa oproti stavu techniky dosiahne podstatné zlepšenie chute.This results in a substantial improvement in taste compared to the prior art.
Riešenie podľa vynálezu viedlo ku konštrukcii filtra, ktorá pôsobí viacstupňovým spôsobom:The solution according to the invention has led to a filter construction which operates in a multi-stage manner:
V prvom stupni sa v časti filtra, privrátenej k tabakovému povrazcu, na veľmi krátkej dráhe nastavia hodnoty kondenzátu a nikotínu. V druhom stupni dôjde ku zníženiu priemeru filtra, používaného hlavným prúdom dymu, čo dym v tejto oblasti urýchli na približne trojnásobnú rýchlosť. Taká konštrukcia filtra vedie pri malých hodnotách kondenzátu k značnému zvýšeniu arómy oproti obvyklému filtru. Ukázalo sa totiž, že ako zloženie dymu, tak aj stredná veľkosť kvapiek sú ovplyvňované zmenou rýchlosti prúdenia, a že sa tak dá aromatický dojem a tým chuť pri značne zvýšených rýchlostiach prúdenia zvýšiť.In the first stage, condensate and nicotine values are set on a very short path in the portion of the filter facing the tobacco rod. In the second stage the diameter of the filter used by the mainstream smoke will be reduced, which will accelerate the smoke in this area to approximately three times the speed. Such a filter design leads to a significant increase in aroma compared to a conventional filter at low condensate values. Indeed, it has been shown that both the composition of the smoke and the mean droplet size are influenced by the variation of the flow velocity, and thus the aromatic impression and thus the taste can be increased at considerably increased flow velocities.
Pretože u cigarety podľa vynálezu sú odpor v ťahu a retencia oddelené, dá sa okrem toho pre fajčiara dosiahnuť veľmi príjemná ťažnosť.Since the tensile resistance and the retention are separated in the cigarette according to the invention, a very pleasant ductility can also be achieved for the smoker.
Prehľad obrázkov na výkresochBRIEF DESCRIPTION OF THE DRAWINGS
Vynález je ďalej bližšie opísaný a objasnený na príklade jeho uskutočnenia podľa pripojeného výkresu, ktorý schematicky znázorňuje cigaretu s filtrom.The invention is described in more detail below with reference to the accompanying drawing, which shows schematically a filter cigarette.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Výkres ukazuje v schematickom znázornení cigaretu s filtrom s tabakovým povrazcom 6 a filtrom 7, ktoré sú obvyklým spôsobom usporiadané kolineárne za sebou, a ktoré sú spolu spojené pomocou obalového papieru 8. Obvykle je tabakový povrazec dlhý medzi 55 a 75 mm, zatiaľ čo dĺžka filtra je 21 až 27 mm. Obalový papier 8 prekrýva rozhranie medzi filtrom 7 a tabakovým povrazcom 8 približne o 2 až 5 mm. Ako filtračné materiály prichádzajú pre filter 7 do úvahy plošné, vláknité alebo granulované filtračné materiály, ako je celulóza, ester celulózy, výhodne acetát celulózy, filtračný materiál Meltblown, vyrobený napríklad podľa spisu WO 97/33026, filtračný materiál Airlaid, vyrobený napríklad podľa spisu US 4 375 447, s aditívami miešateľné filtračné materiály, tabak, iné filtračné materiály ľahko podliehajúce tleniu, alebo termoplastické filtračné vlákna.The drawing shows in a schematic representation a cigarette with a tobacco rod filter 6 and a filter 7, which are arranged in a collinear sequence in a conventional manner and connected together by means of wrapping paper 8. Typically, the tobacco rod is between 55 and 75 mm long while the filter length is 21 to 27 mm. The wrapping paper 8 overlaps the interface between the filter 7 and the tobacco rod 8 by approximately 2 to 5 mm. Suitable filter materials for the filter 7 are planar, fibrous or granular filter materials, such as cellulose, cellulose ester, preferably cellulose acetate, Meltblown filter material, manufactured for example according to WO 97/33026, Airlaid filter material, manufactured for example according to US No. 4,375,447, additive miscible filter materials, tobacco, other filterable materials capable of being decomposed, or thermoplastic filter fibers.
Pridanie aditív sa môže realizovať pomocou ich rozptýlenia alebo nastriekania na filtračné materiály, napríklad vlákna, alebo aj priamou injekciou do povrazca materiálu.Addition of the additives can be effected by dispersing them or spraying them on filter materials, for example fibers, or even by direct injection into the strand of material.
Ako aditíva pre filtračný materiál prichádzajú do úvahy: aromatické látky, kyseliny alebo zásady v suspendovanej alebo v rozpustenej forme, alebo selektívne pôsobiace adsorbenty, ako je aktívne uhlie alebo SÍO2. Pridaním kyselín alebo zásad sa dajú ovplyvňovať hodnoty pH spektier častíc.Suitable additives for the filter material are: flavorings, acids or bases in suspended or dissolved form, or selectively acting adsorbents, such as activated carbon or SiO2. The pH of the particle spectra can be influenced by the addition of acids or bases.
Ďalšími aditívami so selektívnym retenčným účinkom sú organické kyseliny a ich soli, kovy a oxidy kovov, komponenty s obsahom dusíka, iónomeničové systémy, napríklad zeolity, alkoholy, polyfenoly a deriváty porfyrínu.Other selective retention additives are organic acids and their salts, metals and metal oxides, nitrogen-containing components, ion exchange systems such as zeolites, alcohols, polyphenols and porphyrin derivatives.
Na tabakový povrazec 6 sa najskôr napojuje zo strany tabakového povrazca časť 3. filtra v tvare tak zvaného monofiltra, na ktorý sa na konci odvrátenom od tabakového povrazca 6 napojuje zo strany úst časť 4 filtra v tvare koaxiálneho filtra.First, the so-called monofilter-shaped filter part 3 is attached to the tobacco rod 6 by the tobacco-rod side, to which a coaxial-shaped filter portion 4 is connected from the mouth at the end facing away from the tobacco-rod 6.
Monofilter, tvoriaci časť 3. filtra zo strany povrazca, je vyrobený z jedného z vyššie uvedených filtračných materiálov, výhodne z acetátu celulózy, s jednotlivým titrom 2,50 den a celkovým titrom 35 000 den, a poprípade zmiešaný s aktívnym uhlím.The monofilament forming part of the strand filter 3 is made from one of the above filter materials, preferably cellulose acetate, with an individual titer of 2.50 days and a total titer of 35,000 days, and optionally mixed with activated carbon.
Vonkajší priemer časti 3. filtra zo strany tabakového povrazca je v príklade uskutočnenia 7,8 mm, jeho dĺžka je 13,0 mm. Pokles tlaku v časti filtra zo rThe outside diameter of the tobacco strand portion 3 in the exemplary embodiment is 7.8 mm, its length being 13.0 mm. Pressure drop in the filter part of r
strany tabakového povrazca má byť napríklad 30 až 50 mm vodného stĺpca, výhodne 42 mm vodného stĺpca.The side of the tobacco rod should be, for example, 30 to 50 mm water column, preferably 42 mm water column.
Výlučne v oblasti časti 3. filtra zo strany tabakového povrazca je obalový papier 8 vybavený ako ventilačnými prostriedkami ventilačnými otvormi 5, ktoré sú usporiadané vo forme jedného až troch radov, výhodne dvoch radov otvorov okolo dokola filtra 7, v oblasti časti 4 filtra zo strany úst je naproti tomu obalový papier 8. úplne nepriepustný. Cez ventilačné otvory 5. sa do filtra 7 nasáva ventilačný vzduch, čo vedie k tomu, že sa už v oblasti časti 3. filtra zo strany tabakového povrazca redukujú hodnoty kondenzátu a nikotínu hlavného prúdu dymu, privádzaného z tabakového povrazca 6. Odborníkovi je známe, ako je treba vytvoriť ventilačné otvory, napríklad na mechanickom alebo elektrostatickom princípe alebo perforovaním pomocou laseru. Inými, tiež známymi ventilačnými prostriedkami, sú kanyly alebo úspory materiálu.Only in the region of the tobacco strand part 3 of the filter, the wrapping paper 8 is provided as ventilation means with vent holes 5, which are arranged in the form of one to three rows, preferably two rows of apertures around the filter 7, on the other hand, the wrapping paper 8 is completely impermeable. Ventilation air is sucked into the filter 7 through the air vents 5, which results in the tobacco strand condensate and nicotine condensate and nicotine levels being reduced in the region of the filter section 3. such as ventilation openings, for example on a mechanical or electrostatic principle or by laser perforation. Other ventilation means, also known, are cannulae or material savings.
Časť 4 filtra zo strany úst, tvoriaca koaxiálny filter, má jadro I a plášť 2, obklopujúci koaxiálne jadro LThe mouth portion 4 of the filter forming the coaxial filter has a core I and a sheath 2 surrounding the coaxial core L
Pokles tlaku v jadre i môže byť v rozsahu medzi 10 a 50 mm vodného stĺpca. Plášť je vytvorený tak, že jeho pokles tlaku je prinajmenšom o faktor 2 väčší, než pokles tlaku v jadre L Plášť 2 môže byť tiež pre dym nepriepustný.The pressure drop in the core 1 may be between 10 and 50 mm water column. The sheath is designed such that its pressure drop is at least a factor 2 greater than the pressure drop in the core L. The sheath 2 may also be impermeable to smoke.
Príklad: Uskutočnenie s filtrom dlhým 21 mmExample: Design with 21 mm filter
Jadro i malo priemer 4,0 mm pri dĺžke 8,0 mm. V príklade uskutočnenia bolo vyrobené z acetátu celulózy s jednotlivým titrom 6,0 den a celkovým titrom 17 000 den. Odpor v ťahu alebo pokles tlaku v jadre 1 bol okolo 20 mm vodného stĺpca.The core 1 had a diameter of 4.0 mm at a length of 8.0 mm. In the exemplary embodiment, it was made from cellulose acetate with an individual titer of 6.0 days and a total titer of 17,000 days. The tensile resistance or pressure drop in core 1 was about 20 mm water column.
Plášť 2, koaxiálne obklopujúci jadro 1, mal vnútorný priemer 4,0 mm a vonkajší priemer 7,8 mm pri dĺžke tiež 8,0 mm. Ako materiál bol použitý acetát celulózy s jednotlivým titrom 2,1 den a celkovým titrom 55 000 den, čo viedlo k poklesu tlaku 120 mm vodného stĺpca.The shell 2 coaxially surrounding the core 1 had an inside diameter of 4.0 mm and an outside diameter of 7.8 mm at a length of 8.0 mm. Cellulose acetate with an individual titer of 2.1 days and a total titer of 55,000 days was used as the material, resulting in a pressure drop of 120 mm water column.
Dohromady mal teda koaxiálny filter dĺžku 8,0 mm pri priemere 7,8 mm.Taken together, the coaxial filter had a length of 8.0 mm and a diameter of 7.8 mm.
Ako rozsah pre iné príklady uskutočnenia prichádzajú do úvahy: pre jadro jednotlivý titer v rozsahu 3,0 mm až 8,0 den, výhodne 6,0 den, a celkový titer v rozsahu 15 000 až 50 000 den, výhodne 17 000 den. Pre plášť jednotlivý titer v rozsahu 1,5 až 3,0 den, výhodne 2,1 den, a celkový titer v rozsahu 40 000 až 75 000 den, výhodne 55 000 den.Suitable ranges for other exemplary embodiments are: for the core, a single titer in the range of 3.0 mm to 8.0 days, preferably 6.0 days, and a total titer in the range of 15,000 to 50,000 days, preferably 17,000 days. For the sheath, a single titer in the range of 1.5 to 3.0 days, preferably 2.1 days, and a total titer in the range of 40,000 to 75,000 days, preferably 55,000 days.
Rozsah pre jednotlivý titer zo strany tabakového povrazca je 1,5 až 5 den, a pre celkový titer 15 000 až 60 000 den.The range for a single titer by the strand is 1.5 to 5 days, and for a total titer of 15,000 to 60,000 days.
Vyššie uvedený príklad ukazuje, že oproti rýchlosti prúdenia v časti filtra zo strany povrazca bolo v jadre dosiahnuté približne trojnásobné zvýšenie rýchlosti prúdenia.The above example shows that an approximately three-fold increase in flow speed was achieved in the core compared to the flow rate in the strand portion of the filter.
