Abstract

The cigarette, which has less than (1) mg of tar, includes a filter which comprises, on the tobacco side, a paper filter (T1) with a very high resistance to drawing and a very high filtration coefficient. On the mouth side is a cellulose acetate filter (T3) with a very low resistance to drawing and a very low filtration coefficient. Aromatisation means able to recreate the tobacco taste are distributed along the filter section (3) in an aromatised zone (T2) located upstream of the acetate filter. A ventilation means (P) is arranged such that the ventilation air path inside the aromatic zone is shorter than the path of the smoke flow coming from the tobacco section (1).

Description

La présente invention concerne une cigarette à très faible faux de goudron qui présente une résistance au tirage acceptable et cependant un goût de tabac équivalent à celui d'une cigarette classique à rendement en goudron plus fort.The present invention relates to a very low false tar cigarette which has an acceptable draft resistance and yet a tobacco taste equivalent to that of a conventional cigarette with a higher tar yield.

D'une façon générale, on sait que pour réduire le faux de substances indésirables, en particulier le taux de goudron, on utilise des filtres plus ou moins complexes en un ou plusieurs tronçons, étant entendu que plus le taux de filtration d'un tronçon est élevé, plus la résistance au tirage est importante et s'écarte de la norme acceptable pour le fumeur.Generally, we know that to reduce the fake of substances undesirable, in particular the tar rate, more or less filters are used less complex in one or more sections, it being understood that the higher the rate the filtration of a section, the higher the resistance to draft deviates from the norm acceptable to the smoker.

Pour résoudre ce problème, on a proposé de réaliser des filtres multi-tronçons comprenant, côté tabac, un tronçon à fort taux de filtration et côté bouche, un tronçon à faible résistance au tirage, des orifices de ventilation étant prévus au niveau de la jonction entre les deux filtres.To solve this problem, it has been proposed to produce multi-section filters including, on the tobacco side, a section with a high filtration rate and on the mouth side, a section with low draft resistance, ventilation holes being provided at the level of the junction between the two filters.

Grâce à ces dispositions, la fumée traversant le tronçon côté bouche est diluée dans le courant de ventilation et l'on obtient donc une résistance au tirage acceptable.Thanks to these arrangements, the smoke passing through the section on the mouth side is diluted in the ventilation current and we therefore obtain a resistance to draft acceptable.

L'inconvénient de cette solution provient du fait que la fumée, fortement filtrée dans le premier tronçon et diluée dans le second tronçon avec de l'air ambiant, ne présentera plus les propriétés organoleptiques souhaitées. The disadvantage of this solution comes from the fact that the smoke, strongly filtered in the first section and diluted in the second section with ambient air, will no longer exhibit the desired organoleptic properties.

Par ailleurs, comme il résulte des commentaires développés dans le brevet EP 0 608 047, l'usage de filtres papier présentant des taux de filtration élevés (dans la gamme des taux de filtration recherchés) présente l'inconvénient supplémentaire de dénaturer le goût du tabac et d'ajouter une note aromatique désagréable.Furthermore, as follows from the comments developed in the patent EP 0 608 047, the use of paper filters with high filtration rates (in the range of desired filtration rates) has the disadvantage additional to distort the taste of tobacco and add an aromatic note unpleasant.

On a donc tenté de masquer ce mauvais goût par l'incorporation d'aromates présentant un goût franchement différent de celui du tabac (menthol - anéthol).So we tried to mask this bad taste by incorporating herbs with a frankly different taste than tobacco (menthol - anethole).

Toutefois, comme cela est précisé dans le brevet FR 2 459 011, l'idéal serait d'aromatiser la fumée au moyen d'extraits de tabac ou d'arômes synthétiques de tabac. Or, pour obtenir une aromatisation suffisante, une quantité relativement importante d'aromates coûteux est alors nécessaire. En outre, ces aromates se volatilisent et deviennent inefficaces très rapidement, ce qui exclut un entreposage prolongé des cigarettes. Ce document propose donc d'incorporer a un filtre non ventilé, des granules de silicate de magnésium hydraté chargés d'aromates et placés dans le courant chaud et humide de la fumée de la cigarette. Cette solution paraít donc inappropriée (voire même incompatible) avec la réalisation d'une cigarette à très faible taux de goudron exigeant l'emploi d'un filtre ventilé du type de celui précédemment décrit.However, as specified in patent FR 2 459 011, the ideal would be flavor the smoke with tobacco extracts or synthetic flavorings tobacco. However, to obtain sufficient flavoring, a relatively small quantity large quantity of expensive spices is then necessary. In addition, these spices are volatilize and become ineffective very quickly, which excludes a prolonged storage of cigarettes. This document therefore proposes to incorporate into a non-ventilated filter, hydrated magnesium silicate granules loaded herbs and placed in the hot, humid stream of smoke from the cigarette. This solution therefore seems inappropriate (or even incompatible) with the production of a cigarette with a very low tar content the use of a ventilated filter of the type described above.

Par ailleurs, l'usage de gaines poreuses aromatisées permettant l'aromatisation du flux d'air de ventilation préalablement à son mélange avec le flux de fumée traversant la portion de filtre à haut pouvoir de filtrage augmente la complexité du filtre et son coût. Cette solution présente en outre l'inconvénient d'engendrer un mélange hétérogène sur le plan gustatif du flux gazeux aspiré par le fumeur : seul le flux de ventilation (périphérique) est aromatisé.In addition, the use of porous flavored sheaths allowing flavoring ventilation air flow before mixing with the smoke flow crossing the filter portion with high filtering capacity increases the complexity the filter and its cost. This solution also has the disadvantage to generate a heterogeneous mixture in terms of taste of the aspirated gas flow by the smoker: only the ventilation flow (peripheral) is flavored.

L'invention a donc plus particulièrement pour but de supprimer ces inconvénients. The invention therefore more particularly aims to remove these disadvantages.

Elle propose à cet effet une cigarette à très faible taux de goudron (inférieur ou égal à 1 mg) comprenant un filtre qui comporte au moins :

  • côté tabac, un tronçon de filtre en papier à très forte résistance au tirage et à coefficient de filtration très élevé,
  • côté bouche, un tronçon de filtre en acétate de cellulose à très faible résistance au tirage et à très faible coefficient de filtration,
  • des moyens d'aromatisation aptes à recréer le goût du tabac, ces moyens étant répartis sur toute la section du filtre dans une zone aromatisée située en amont du tronçon de filtre en acétate, et
  • des moyens de ventilation disposés de manière à ce que le trajet moyen du flux d'air de ventilation à l'intérieur de la zone aromatisée soit plus court que le trajet moyen du flux de fumée provenant du tronçon tabac.
To this end, it offers a cigarette with a very low tar content (less than or equal to 1 mg) comprising a filter which comprises at least:
  • tobacco side, a section of paper filter with very high draft resistance and very high filtration coefficient,
  • mouth side, a section of cellulose acetate filter with very low draft resistance and very low filtration coefficient,
  • flavoring means capable of recreating the taste of tobacco, these means being distributed over the entire section of the filter in a flavored zone situated upstream of the acetate filter section, and
  • ventilation means arranged so that the average path of the flow of ventilation air inside the flavored zone is shorter than the average path of the flow of smoke from the tobacco section.

Grâce à ces dispositions, le flux de fumée émanant du tronçon tabac et qui se propage dans la région centrale du tronçon de filtre en acétate subira au début (c'est-à-dire pendant la période où le tronçon papier dénature le plus le goût) une aromatisation plus forte (longueur du trajet + chaleur et humidité du flux) que celle subie par le flux de ventilation dont le débit est plus important, le trajet d'aromatisation plus court, mais qui au départ n'a pas mauvais goût.Thanks to these provisions, the flow of smoke emanating from the tobacco section and which propagates in the central region of the acetate filter section will undergo at the start (i.e. during the period when the paper section distorts the taste the most) stronger flavoring (path length + heat and humidity of the flow) than that undergone by the ventilation flow whose flow is greater, the shorter flavoring route, but which initially does not taste bad.

Par contre, lorsque la cigarette se trouve en grande partie consumée, l'aromatisation du flux de fumée (qui est moins affecté par le mauvais goût) devient moins importante (perte du pouvoir d'aromatisation de l'arôme) tandis que l'aromatisation du flux d'air de ventilation s'accroít en raison de l'élévation de température et du taux d'humidité générale du filtre et compense la diminution de l'aromatisation de la fumée. On the other hand, when the cigarette is largely consumed, flavoring the smoke stream (which is less affected by bad taste) becomes less important (loss of flavoring power) while that the aromatization of the ventilation air flow increases due to the elevation temperature and general humidity of the filter and compensates for the reduction in smoke flavoring.

Grâce à ce double processus, on obtient donc, en sortie de la cigarette, un mélange gazeux plus homogène au niveau du goût et dont l'aromatisation exige des quantités moins importantes d'aromates.Thanks to this double process, we thus obtain, at the outlet of the cigarette, a more homogeneous gas mixture in terms of taste and whose flavor requires smaller amounts of aromatics.

Avantageusement, l'aromate sera inclus dans un tronçon de filtre compris entre le tronçon de filtre à coefficient de filtration élevé et le tronçon de filtre à faible coefficient de filtration. Dans ce cas, des orifices de ventilation seront de préférence prévus dans la zone centrale du tronçon de filtre aromatisé.Advantageously, the flavoring will be included in a filter section between the filter section with a high filtration coefficient and the filter section with low filtration coefficient. In this case, ventilation holes will be preferably provided in the central area of the flavored filter section.

Un mode d'exécution d'une cigarette selon l'invention sera décrit ci-après, à titre d'exemple non limitatif avec référence au dessin annexé dans lequel :

  • La figure unique est une coupe axiale partielle d'une cigarette équipée de son filtre.
    • An embodiment of a cigarette according to the invention will be described below, by way of nonlimiting example with reference to the appended drawing in which:
  • The single figure is a partial axial section of a cigarette equipped with its filter.

    • Dans cet exemple, la cigarette se compose d'un tronçon tabac non aromatisé 1, de dimensions usuelles, contenu dans une enveloppe de papier à cigarette 2 et prolongé par un filtre ventilé 3 à trois tronçons T1 à T3 logé dans une manchette tubulaire 4 qui vient en recouvrement sur le tronçon tabac 1 de manière à assurer la liaison mécanique filtre 3/tronçon tabac 1.In this example, the cigarette consists of a non-flavored tobacco section 1, of usual dimensions, contained in an envelope of cigarette paper 2 and extended by a ventilated filter 3 with three sections T 1 to T 3 housed in a tubular cuff 4 which overlaps the tobacco section 1 so as to ensure the mechanical connection of the filter 3 / tobacco section 1.

    Le tronçon tabac 1, à faible rendement en goudron (fort taux de TE) comprend ici une enveloppe poreuse 2 de 40 à 80 pers contenant de 1,5 à 3 % de citrate de sodium et 29 à 35 % de carbonate de calcium CO3 Ca.The tobacco section 1, with a low tar yield (high TE rate) here comprises a porous envelope 2 of 40 to 80 people containing 1.5 to 3% of sodium citrate and 29 to 35% of calcium carbonate CO 3 It.

    Le tronçon de filtre T1 situé côté tabac, d'une longueur de l'ordre de 10 mm, est un tronçon papier de résistance au tirage et filtration très élevées (RT ≈150 - filtration > 80 %). The filter section T 1 located on the tobacco side, with a length of the order of 10 mm, is a paper section with very high draft resistance and filtration (RT ≈150 - filtration> 80%).

    Le tronçon de filtre T3 situé côté bouche, également de l'ordre de 10 mm de longueur, est un tronçon en acétate de cellulose de résistance au tirage RT et de filtration très faibles.The filter section T 3 located on the mouth side, also of the order of 10 mm in length, is a section of cellulose acetate with very low resistance to RT draft and filtration.

    Entre les tronçons T1 et T3 est prévu un tronçon T2 de 5 mm de longueur constituant une chambre contenant une matière adsorbante telle que de la sépiolite aromatisée à l'aide d'un aromate présentant une odeur de tabac.Between the sections T 1 and T 3 is provided a section T 2 of 5 mm in length constituting a chamber containing an adsorbent material such as sepiolite flavored with a flavoring having a tobacco odor.

    La ventilation du filtre 3 est assurée grâce à des perforations P de la manchette 4 situées à environ 13 mm de l'orifice du filtre T3 situé côté bouche, soit au niveau de la région centrale du tronçon T2.The ventilation of the filter 3 is ensured by means of perforations P of the cuff 4 located approximately 13 mm from the orifice of the filter T 3 located on the mouth side, ie at the level of the central region of the section T 2 .

    Compte tenu de ces dispositions, la fumée produite par la combustion du tronçon tabac 1 et dont le flux est indiqué schématiquement par une zone hachurée entre les veines V1 et V2, passe principalement au travers de la région centrale des tronçons T2 et T3, tandis que les flux d'air de ventilation (veines V3, V4) qui passent au travers les perforations P circulent dans une zone annulaire entourant le flux de fumée.In view of these provisions, the smoke produced by the combustion of the tobacco section 1 and whose flow is indicated schematically by a hatched area between the veins V 1 and V 2 , passes mainly through the central region of the sections T 2 and T 3 , while the ventilation air flows (veins V 3 , V 4 ) which pass through the perforations P circulate in an annular zone surrounding the flow of smoke.

    Il apparaít donc clairement que le trajet moyen du flux d'air de ventilation à l'intérieur du tronçon T2 est plus court que le trajet moyen du flux de fumée provenant du tronçon tabac 1.It is therefore clear that the average path of the ventilation air flow inside the section T 2 is shorter than the average path of the flow of smoke from the tobacco section 1.

    On obtient donc le double processus d'aromatisation précédemment évoqué qui conduit à l'obtention d'un mélange gazeux présentant des propriétés organoleptiques satisfaisantes avec un minimum d'aromates (et ce, en dépit du mauvais goût engendré par le tronçon de filtre).We thus obtain the double aromatization process previously mentioned which leads to a gaseous mixture having properties satisfactory organoleptics with a minimum of flavorings (and this, despite the bad taste caused by the filter section).
