Description Description
Domaine technique de l'invention. L'invention concerne une cigarette équipée d'un dispositif d'auto- allumage ainsi qu'un procédé pour allumer une cigarette. Technical Field of the Invention The invention relates to a cigarette equipped with a self-ignition device and a method for lighting a cigarette.
Elle se rapporte au domaine technique des dispositifs pyrotechniques et plus particulièrement ceux destinés à l'allumage de cigarettes et fournissant une alternative aux moyens traditionnels du type briquets ou allumettes. It relates to the technical field of pyrotechnic devices and more particularly those intended for cigarette ignition and providing an alternative to traditional means such as lighters or matches.
État de la technique. Les dispositifs d'auto-allumage de cigarettes illustrant l'art antérieur sont décrits dans les documents brevets suivants : FR 2 905 231 (Charli ABISDID), BG 407 714 (M. MARGOLIS), DE 3 509 293 (LIECHTENSTEIN RICHARD VON), EP 0 066 021 (YOO, BYUNG EON) FR 7 539 535 (TOKYO ENGINEERING CO.) D5 : GB 314 145 (Piedad et Alejandro LIFCHUZ), FR 709 175 (Giulio TURRI), JP 2005 5 224 232 (ISHIKAWA JOJI), GB 406 153 (Ansley HERMAN FOX). Ces dispositifs comprennent une matière d'amorçage configurée pour enflammer une matière inflammable sous l'effet d'un choc ou d'un frottement. Les bandes de frottement généralement utilisées, s'usent au fur et à mesure que l'on allume des cigarettes. Et plus la bande est usée, plus il s'avère difficile d'allumer une cigarette. Pour palier cet inconvénient, on connaît par les documents FR 1 014 899 (Louis Thomas FONDO), BG 1 012 826 (Pierre JACQUET), BG 97 941 (BONCHEV MIROSLAV B.), GB 356 861 (Robert SUTHERLAND), GB 752 365 (Hans HANNO MOSER), GB 790 341 (Kurt KORBER), des dispositifs d'auto- allumage comprenant une matière chimique primaire placée à l'extrémité à allumer de la cigarette, et une matière chimique secondaire incompatible avec la matière primaire. Ces dispositifs utilisent le principe d'incompatibilité de matières chimiques qui s'enflamment spontanément lorsqu'elles sont mises en contact l'une de l'autre. En pratique, la matière chimique secondaire est : State of the art Cigarette self-ignition devices illustrating the prior art are described in the following patent documents: FR 2 905 231 (Charli ABISDID), BG 407 714 (M. MARGOLIS), DE 3 509 293 (LIECHTENSTEIN RICHARD VON), EP 0 066 021 (YOO, BYUNG EON) FR 7,539,535 (TOKYO ENGINEERING CO.) D5: GB 314,145 (Piedad and Alejandro LIFCHUZ), FR 709,175 (Giulio TURRI), JP 2005 5,224,232 (ISHIKAWA JOJI), GB 406153 (Ansley HERMAN FOX). These devices include a firing material configured to ignite a flammable material under the effect of shock or friction. The commonly used rubs wear out as you light cigarettes. And the longer the band is worn, the more difficult it is to light a cigarette. To overcome this drawback, documents FR 1 014 899 (Louis Thomas FONDO), BG 1 012 826 (Pierre JACQUET), BG 97 941 (BONCHEV MIROSLAV B.), GB 356 861 (Robert SUTHERLAND), GB 752 365 are known. (Hans HANNO MOSER), GB 790 341 (Kurt KORBER), self-ignition devices comprising a primary chemical material placed at the cigarette-smoking end, and a secondary chemical material incompatible with the primary material. These devices use the principle of incompatibility of chemical materials that ignite spontaneously when brought into contact with each other. In practice, the secondary chemical is:
- soit conditionnée sur l'une des faces du paquet de cigarettes de sorte que lors de la manipulation dudit paquet, ladite matière chimique secondaire peut se détacher, entraînant, de fait, des difficultés pour allumer ultérieurement des cigarettes,  - is packaged on one side of the pack of cigarettes so that when handling said package, said secondary chemical material can come off, causing, in fact, difficulties to later light cigarettes,
- soit conditionnée dans des contenants individuels, de telle sorte qu'il est indispensable de ne pas oublier d'emporter lesdits contenants pour allumer des cigarettes. - is packaged in individual containers, so that it is essential not to forget to bring these containers to light cigarettes.
On connaît plus particulièrement par le document US 3 109 435 (PALEY), une cigarette équipée d'un dispositif d'auto-allumage comprenant : une matière chimique primaire placée à l'extrémité à allumer de la cigarette, et une matière chimique secondaire incompatible avec ladite matière primaire. La matière secondaire est contenue dans un réceptacle amovible configuré pour se positionner contre l'extrémité à allumer, selon un agencement permettant la mise en contact de ladite matière secondaire avec la matière primaire. Le réceptacle décrit dans ce document est initialement disposé sur l'extrémité à allumer. Avec un tel dispositif, les risques de détachement accidentel du réceptacle et de sa mise en contact avec la matière primaire d'allumage ne peuvent être exclus. Face à cet état de chose, l'invention a pour principal objectif de fournir un dispositif permettant un allumage aisé d'une cigarette, tout en supprimant les déficiences liées aux conditionnements de la matière chimique secondaire connues de l'art antérieur. US Pat. No. 3,109,435 (PALEY) discloses a cigarette equipped with a self-ignition device comprising: a primary chemical material placed at the end of the cigarette, and an incompatible secondary chemical substance. with said primary material. The secondary material is contained in a removable receptacle configured to be positioned against the end to be ignited, in an arrangement for contacting said secondary material with the primary material. The receptacle described in this document is initially arranged on the end to ignite. With such a device, the risk of accidental detachment of the receptacle and its contact with the primary ignition material can not be excluded. Faced with this state of affairs, the invention has the main objective of providing a device for easy ignition of a cigarette, while eliminating the deficiencies related to the secondary chemical material conditioning known from the prior art.
L'invention a également pour objet de fournir un dispositif d'auto- allumage facile d'utilisation, de conception simple et peu onéreux. The invention also aims to provide a self-ignition device easy to use, simple and inexpensive design.

Cette cigarette est remarquable en ce que la matière secondaire est contenue dans un réceptacle initialement disposé à l'une des extrémités de la cigarette, selon un agencement empêchant toute mise en contact de ladite matière secondaire avec la matière primaire. Et en ce que le réceptacle est amovible, et configuré pour se positionner contre l'extrémité à allumer, selon un agencement permettant la mise en contact de la matière secondaire avec la matière primaire.  This cigarette is remarkable in that the secondary material is contained in a receptacle initially disposed at one end of the cigarette, in an arrangement preventing any contact of said secondary material with the primary material. And in that the receptacle is removable, and configured to position against the end to ignite, in an arrangement for contacting the secondary material with the primary material.
Le fait de pouvoir associer à chaque cigarette un réceptacle unitaire permet à l'utilisateur d'avoir systématiquement une dose suffisante de matière secondaire à sa disposition, lui assurant un allumage efficace de ses cigarettes. En outre la conception d'un tel réceptacle est aisément réalisable au stade industriel et son utilisation séduisante pour les utilisateurs. Pour éviter qu'une cigarette ne puisse s'allumer accidentellement lorsque le paquet dans lequel elle est stockée, est secoué ou écrasé, le réceptacle est avantageusement configuré pour : The fact of being able to associate with each cigarette a unitary receptacle allows the user to systematically have a sufficient dose of secondary material at his disposal, ensuring him an effective ignition of his cigarettes. In addition the design of such a receptacle is easily achievable at the industrial stage and its attractive use for users. To prevent a cigarette from being ignited accidentally when the package in which it is stored is shaken or crushed, the receptacle is advantageously configured to:
- se positionner à l'extrémité d'inhalation opposée à l'extrémité à allumer de la cigarette, pour que la matière chimique secondaire soit initialement physiquement séparée de la matière chimique primaire,  positioning itself at the opposite inhalation end to the end of the cigarette, so that the secondary chemical substance is initially physically separated from the primary chemical material,
- s'emmancher sur l'extrémité à allumer, pour mettre en contact la matière chimique secondaire avec la matière chimique primaire et enflammer l'extrémité à allumer de la cigarette.  - slip on the end to ignite, to bring the secondary chemical into contact with the primary chemical material and ignite the end to ignite the cigarette.
Selon un premier mode de réalisation de l'invention permettant de facilement et rapidement détacher le réceptacle de l'extrémité d'inhalation et le positionner contre l'extrémité à allumer, ledit réceptacle comprend une zone de fixation configurée pour : According to a first embodiment of the invention making it possible to easily and quickly detach the receptacle from the inhalation end and position it against the end to be ignited, said receptacle comprises an attachment zone configured to:
- s'emmancher sur l'extrémité d'inhalation opposée à l'extrémité à allumer de la cigarette, - get into the opposite end of the inhalation end of the cigarette,
- et s'emmancher sur l'extrémité à allumer.  - and get on the end to light.
Selon un deuxième mode de réalisation permettant de limiter les risques de détachement accidentel du réceptacle de l'extrémité d'inhalation, ledit réceptacle est initialement positionné, préférentiellement fixé, à l'extrémité d'inhalation opposée à l'extrémité à allumer, ledit réceptacle étant sécable de manière à permettre une manipulation indépendante de la cigarette et dudit réceptacle. According to a second embodiment making it possible to limit the risks of accidental detachment of the receptacle from the inhalation end, said receptacle is initially positioned, preferentially attached, to the inhalation end opposite the end to be ignited, said receptacle being breakable so as to allow independent handling of the cigarette and said receptacle.
Pour intégrer rapidement et efficacement le réceptacle à une cigarette, lors de la fabrication de cette dernière : To quickly and efficiently integrate the receptacle with a cigarette, during the manufacture of this cigarette:
- un filtre peut être fixé par un emballage sur l'extrémité d'inhalation de la cigarette,  a filter can be fixed by a package on the inhalation end of the cigarette,
- le réceptacle peut être un tube cylindrique disposé dans le prolongement du filtre, l'emballage assurant la fixation dudit tube sur ledit filtre. En l'absence de filtre, le réceptacle est un tube cylindrique disposé dans le prolongement de l'extrémité d'inhalation, ledit réceptacle étant fixé par un emballage directement sur ladite extrémité d'inhalation. - The receptacle may be a cylindrical tube disposed in the extension of the filter, the packaging ensuring the attachment of said tube on said filter. In the absence of a filter, the receptacle is a cylindrical tube disposed in the extension of the inhalation end, said receptacle being fixed by a package directly on said inhalation end.
Pour que l'utilisateur puisse facilement séparer le réceptacle du reste de la cigarette, l'emballage comprend avantageusement une partie fragile au niveau de la jonction du filtre (ou de l'extrémité d'inhalation) et dudit réceptacle. Cette partie fragile permettant de détacher manuellement le réceptacle par traction, flexion, torsion ou rotation. So that the user can easily separate the receptacle from the rest of the cigarette, the package advantageously comprises a fragile portion at the junction of the filter (or the inhalation end) and said receptacle. This fragile part for manually detaching the receptacle by traction, bending, twisting or rotation.
Dans le but de faciliter le positionnement du réceptacle contre l'extrémité à allumer, ledit réceptacle se présente préférentiellement sous la forme d'un tube cylindrique configuré pour s'emmancher sur ladite extrémité à allumer et mettre en contact la matière chimique secondaire avec la matière chimique primaire. In order to facilitate the positioning of the receptacle against the end to be ignited, said receptacle is preferably in the form of a cylindrical tube configured to engage on said end to ignite and bring the secondary chemical material into contact with the material primary chemical.
Dans une variante de réalisation, le réceptacle est initialement fixé à l'extrémité à allumer. Le réceptacle peut alors comprendre : In an alternative embodiment, the receptacle is initially attached to the end to be ignited. The receptacle may then include:
- une première zone de fixation étanche vis-à-vis de la matière chimique secondaire, ladite première zone étant configurée pour s'emmancher sur l'extrémité à allumer de la cigarette, pour que ladite matière chimique secondaire soit initialement physiquement séparée de la matière chimique primaire, a first sealing zone with respect to the secondary chemical material, said first zone being configured to engage on the end to be ignited of the cigarette, so that said secondary chemical substance is initially physically separated from the material primary chemical
- une seconde zone de fixation étanche vis-à-vis de la matière chimique secondaire, ladite seconde zone étant configurée pour s'emmancher sur l'extrémité à allumer, pour mettre en contact ladite matière chimique secondaire avec la matière chimique primaire et enflammer l'extrémité à allumer de la cigarette. Le réceptacle peut également être un tube cylindrique disposé dans le prolongement de l'extrémité à allume, ledit réceptacle étant fixé par un emballage directement sur ladite extrémité à allumer. L'emballage comprend avantageusement une partie fragile permettant de détacher manuellement le réceptacle par traction, flexion, torsion ou rotation. a second sealing zone with respect to the secondary chemical material, said second zone being configured to be engaged on the end to be ignited, for bringing said secondary chemical material into contact with the primary chemical substance and igniting the end to light cigarette. The receptacle may also be a cylindrical tube arranged in the extension of the lighter end, said receptacle being fixed by a package directly on said end to be ignited. The package advantageously comprises a fragile portion for manually detaching the receptacle by traction, bending, twisting or rotation.
Pour éviter que la matière secondaire sorte du réceptacle lorsque le paquet dans lequel la cigarette est conditionnée est écrasé, ladite matière secondaire est préférentiellement conditionnée dans une ou plusieurs gélules agencées dans le réceptacle, ledit réceptacle comportant une ou plusieurs parois flexibles permettant de rompre lesdites gélules par écrasement lorsqu'un effort de pression est exercé sur ladite ou lesdites parois flexibles. To prevent the secondary material from leaving the receptacle when the pack in which the cigarette is packaged is crushed, said secondary material is preferentially packaged in one or more capsules arranged in the receptacle, said receptacle comprising one or more flexible walls for breaking said capsules. by crushing when a pressure force is exerted on said one or more flexible walls.
Selon encore une autre caractéristique avantageuse de l'invention permettant d'assurer un conditionnement optimal de la matière secondaire tout en facilitant son extraction du réceptacle, ledit réceptacle est fermé par un opercule d'étanchéité frangible. According to yet another advantageous feature of the invention for ensuring optimal conditioning of the secondary material while facilitating its extraction from the receptacle, said receptacle is closed by a frangible sealing cover.
Selon encore une autre caractéristique avantageuse de l'invention permettant de respecter normes sanitaires en vigueur, la matière chimique primaire comprend du permanganate de potassium et la matière chimique secondaire comprend de la glycérine. Le couple de matières chimiques primaire et secondaire « permanganate de potassium/glycérine » permet d'enflammer rapidement l'extrémité à allumer de la cigarette tout en s'éliminant facilement avec les cendres lors de la combustion de ladite extrémité. According to yet another advantageous characteristic of the invention making it possible to comply with sanitary standards in force, the primary chemical material comprises potassium permanganate and the secondary chemical substance comprises glycerine. The pair of primary and secondary chemicals "potassium permanganate / glycerin" quickly ignites the end to ignite the cigarette while easily removed with ashes during the combustion of said end.
Un autre aspect de l'invention concerne un procédé pour allumer une cigarette dans lequel : Another aspect of the invention relates to a method for lighting a cigarette in which:
- on place une matière chimique primaire à l'extrémité à allumer de la cigarette, - on met en contact la matière chimique primaire avec une matière chimique secondaire incompatible de façon à enflammer l'extrémité à allumer. a primary chemical material is placed at the end to light the cigarette, the primary chemical material is brought into contact with an incompatible secondary chemical material so as to ignite the end to be ignited.

D'autres avantages et caractéristiques de l'invention apparaîtront mieux à la lecture de la description d'un mode de réalisation préféré qui va suivre, en référence aux dessins annexés, réalisés à titre d'exemples indicatifs et non limitatifs et sur lesquels : Other advantages and characteristics of the invention will appear better on reading the description of a preferred embodiment which will follow, with reference to the accompanying drawings, carried out as indicative and non-limiting examples and in which:
- les figures 1 à 6 représentent schématiquement les différentes étapes permettant d'allumer une cigarette au moyen d'un dispositif auto-allumable conforme à l'invention,  FIGS. 1 to 6 diagrammatically show the different steps for lighting a cigarette by means of a self-igniting device according to the invention,
- les figures 7a et 7b schématisent un premier exemple de réalisation d'un dispositif auto-allumable conforme à l'invention, le réceptacle étant respectivement disposé au niveau de l'extrémité d'inhalation de la cigarette et au niveau de l'extrémité à allumer de ladite cigarette,  FIGS. 7a and 7b schematize a first embodiment of a self-ignitable device according to the invention, the receptacle being respectively disposed at the inhalation end of the cigarette and at the end at lighting up said cigarette,

- les figures 9a et 9b schématisent un troisième exemple de réalisation d'un dispositif auto-allumable conforme à l'invention, le réceptacle étant disposé au niveau de l'extrémité à allumer de la cigarette. Modes de réalisation de l'invention. L'invention permet d'auto-allumer une cigarette 1. On entend par- Figures 9a and 9b schematically a third embodiment of a self-ignitable device according to the invention, the receptacle being disposed at the end of the lit cigarette. Embodiments of the invention The invention makes it possible to self-ignite a cigarette 1. By
« cigarette », une cigarette classique avec ou sans filtre, un cigarillo, un cigare, ou autre objet similaire susceptible d'être consommé par un fumeur. Comme schématisée sur les figures 1 à 6, une cigarette 1 se présente généralement sous la forme d'un cylindre formé d'une feuille de papier 2 et à l'intérieur duquel sont disposées des feuilles de tabac hachées 3. Elle a un diamètre pouvant varier de 3 mm à 7 mm et une longueur pouvant varier 60 mm à 100 mm. Elle comporte une extrémité à allumer 4 et une extrémité d'inhalation 5 opposée à ladite extrémité à allumer. L'extrémité d'inhalation 5 peut notamment comporter un filtre 6. "Cigarette" means a conventional cigarette with or without a filter, a cigarillo, a cigar, or other similar object likely to be consumed by a smoker. As schematized in Figures 1 to 6, a cigarette 1 is generally in the form of a cylinder formed of a sheet of paper 2 and inside which are disposed chopped tobacco leaves 3. It has a diameter that can vary from 3 mm to 7 mm and a length that can vary from 60 mm to 100 mm. It has an end to ignite 4 and an inhalation end 5 opposite to said end to be ignited. The inhalation end 5 may in particular comprise a filter 6.
Le dispositif auto-allumable objet de l'invention comprend une matière chimique primaire 7 (ou matière « à allumer ») destinée à être placée à l'extrémité à allumer 4 de la cigarette 1. La matière chimique primaire 7 peut être mise en place par imprégnation, enduction, compression, insertion dans les feuilles de tabac 3, d'un liquide, gel, solide, microcapsules, cristaux, granulés, etc. En pratique, la matière primaire 7 est présente sur une profondeur de quelques millimètres depuis l'extrémité à allumer 4. La mise en place de la matière primaire 7 est préférentiellement réalisée au moment de la fabrication de la cigarette 1. The self-ignitable device object of the invention comprises a primary chemical material 7 (or material "to be lit") intended to be placed at the end to ignite 4 of the cigarette 1. The primary chemical material 7 can be put in place by impregnation, coating, compression, insertion into the tobacco leaves 3, a liquid, gel, solid, microcapsules, crystals, granules, etc. In practice, the primary material 7 is present to a depth of a few millimeters from the end to ignite 4. The establishment of the primary material 7 is preferably performed at the time of manufacture of the cigarette 1.
Selon la forme choisie, un séchage de la matière primaire 7 peut être prévu de façon à assurer la compatibilité de la technologie avant un rangement de la cigarette 1 dans un paquet sur une longue durée. En effet, une matière non sèche risquerait de polluer le paquet, pourrait provoquer le collage des cigarettes entre-elles, pourrait salir les doigts, les vêtements de l'utilisateur ou les objets (tels que tables ou cendriers) sur lesquels la cigarette 1 serait posée, etc. Egalement, l'utilisation d'une matière primaire 7 liquide préalablement encapsulée permet de protéger ladite matière primaire d'être accidentellement répandue, tout en permettant à l'utilisateur de rompre cette encapsulation par une action volontaire appropriée (par exemple, par écrasement par pression de l'extrémité de la cigarette 1 entre deux doigts). La technique d'encapsulation peut également être envisagée avec une matière primaire 7 solide. Depending on the shape chosen, drying of the primary material 7 may be provided to ensure the compatibility of the technology prior to storing the cigarette 1 in a package over a long period. In fact, a dry material could pollute the package, could cause the sticking of cigarettes between them, could soil the fingers, the clothes of the user or objects (such as tables or ashtrays) on which the cigarette 1 would be asked, etc. Also, the use of a pre-encapsulated liquid primary material 7 makes it possible to protect said primary material from being accidentally spread, while allowing the user to break this encapsulation by an appropriate voluntary action (for example, by pressure crushing). the end of the cigarette 1 between two fingers). The encapsulation technique can also be envisaged with a solid primary material.
Le dispositif auto-allumable objet de l'invention comprend également une matière chimique secondaire 8 (ou matière « d'allumage ») choisie pour être incompatible avec la matière chimique primaire 7. De fait, les matières primaire et secondaire sont susceptibles de réagir et s'enflammer lorsqu'elles sont en contact l'une de l'autre. Par « enflammer », on entend au sens de la présente invention, produire une énergie thermique (par exemple de 150°C à 700°C), avec ou sans flamme, susceptible d'allumer la cigarette 1. La matière secondaire 8 peut se présenter sous la forme d'un liquide, d'un gel, d'un solide, de microcapsules, de cristaux, de granulés, etc. The self-ignitable device object of the invention also comprises a secondary chemical substance 8 (or "ignition" material) chosen to be incompatible with the primary chemical material 7. In fact, the primary and secondary materials are likely to react and ignite when in contact with each other. For the purposes of the present invention, the term "igniting" means producing a heat energy (for example from 150 ° C. to 700 ° C.), with or without a flame, capable of igniting the cigarette 1. The secondary material 8 may be present in the form of a liquid, a gel, a solid, microcapsules, crystals, granules, etc.
Le couple matière primaire 7/matière secondaire 8 peut par exemple être un couple oxydant/combustible du type permanganate de potassium/glycol ; nitrate d'argent/phosphore rouge ; nitrate d'argent/soufre ; chlorates et acide borique/glycols ; aluminium/teinture d'iode ; sodium métal ou autres métaux de la même famille/eau ou réactants à terminaison alcoolique ; nickel de Ranley ou matériaux phosphoriques/oxydants (MnO2, chlorate) ; nitrocelluloses/acides forts (sulfurique, chloridrique) ; etc. The primary material pair 7 / secondary material 8 may for example be an oxidation / fuel pair of the potassium permanganate / glycol type; silver nitrate / red phosphorus; silver nitrate / sulfur; chlorates and boric acid / glycols; aluminum / iodine tincture; sodium metal or other metals of the same family / water or alcohol-terminated reactants; Ranley nickel or phosphoric / oxidative materials (MnO2, chlorate); nitrocellulose / strong acids (sulfuric, chloridic); etc.
Des substances additionnelles peuvent être utilisées pour diluer, lier, fixer activer ou au contraire ralentir ou passiver les matières chimiques de base incompatibles mises en œuvre dans l'invention. D'autres substances peuvent en outre permettre de renforcer la résistance des matières primaire 7 et secondaire 8 aux conditions ambiantes, notamment l'humidité (par exemple des substances hydrofuges). Il est possible d'améliorer l'inflammabilité du tabac en imprégnant l'extrémité à allumer 4 par une matière « sensibilisante » telle que la nitrocellulose, avant dépôt de la matière primaire 7. Cela a pour avantage de fiabiliser l'allumage tout en autorisant la réduction de la matière primaire 7 au strict minimum. Les quantités respectives de matière chimique primaire 7 et secondaire 8 peuvent varier de 0.1 mg à 5 mg par cigarette. Additional substances may be used to dilute, bind, bind activate or otherwise slow down or passivate the incompatible basic chemical materials used in the invention. Other substances may furthermore make it possible to reinforce the resistance of the primary 7 and secondary 8 materials at ambient conditions, in particular moisture (for example water-repellent substances). It is possible to improve the flammability of tobacco by impregnating the end to ignite 4 by a "sensitizing" material such as nitrocellulose, before deposition of the primary material 7. This has the advantage of making the ignition more reliable while allowing the reduction of the primary material 7 to a minimum. The respective amounts of primary 7 and secondary 8 chemical may vary from 0.1 mg to 5 mg per cigarette.
Préférentiellement, pour respecter les normes sanitaires en vigueur et éliminer tout risque de toxicité, la matière primaire 7 peut comprendre du permanganate de potassium et la matière secondaire 8 peut comprendre de la glycérine. La glycérine est un produit couramment utilisé comme additif alimentaire : elle se présente sous la forme d'un liquide visqueux, transparent, incolore, inodore, non toxique et au goût sucré. Quant au permanganate de potassium, c'est un sel inorganique couramment utilisé comme désinfectant et comme désodorisant. Il est notamment utilisé pour le traitement de l'eau potable. Preferably, to comply with the health standards in force and eliminate any risk of toxicity, the primary material 7 may comprise potassium permanganate and the secondary material 8 may comprise glycerine. Glycerine is a product commonly used as a food additive: it is in the form of a viscous liquid, transparent, colorless, odorless, nontoxic and sweet taste. As for potassium permanganate, it is an inorganic salt commonly used as a disinfectant and as a deodorant. It is used in particular for the treatment of drinking water.
La réaction chimique initiée par ce couple de matières chimiques n'est pas instantanée, une petite période d'incubation de quelques secondes étant nécessaire, sans que cela conduise l'utilisateur à estimer que la cigarette ne s'est pas allumée. La réaction est annoncée par un dégagement préalable de fumée non toxique consistant uniquement en du dioxyde de carbone et de la vapeur d'eau. La réaction n'est pas trop vive, l'effet étant similaire à celui provoqué par la flamme d'un briquet ou d'une allumette. Une fois la réaction terminée, l'extrémité 4 de la cigarette est suffisamment allumée pour laisser le temps au fumeur de porter la cigarette à ses lèvres et de commencer à aspirer les fumées de tabac en l'assurant qu'il n'aspirera pas les fumées de la réaction d'incompatibilité. Cet état des choses sécurise l'auto-allumage de la cigarette 1 et rassure l'utilisateur. En outre, ces deux matières chimiques sont suffisamment stables pour assurer une durée d'utilisation suffisante dans le temps. Pour mettre à la disposition de l'utilisateur, en une seule opération, tout ce dont il a besoin pour allumer sa cigarette dès qu'il l'extrait du paquet, la matière secondaire 8 est contenue dans un réceptacle 9 initialement disposé à l'une des extrémités de la cigarette, selon un agencement empêchant toute mise en contact de ladite matière secondaire avec la matière primaire 7. Ce réceptacle 9 est amovible, et configuré pour se positionner contre l'extrémité à allumer 4, selon un agencement permettant la mise en contact de la matière secondaire 8 avec la matière primaire 7. En pratique, la matière secondaire 8 est disposée dans un réceptacle 9 amovible configuré pour s'emmancher à l'extrémité à allumer 4. Par « emmancher », on entend au sens de la présente invention, la possibilité qu'a le réceptacle 9 à se positionner sur, contre et/ou autour de l'extrémité à allumer 4, avec la possibilité de rester ou non fixer à ladite extrémité. De ce fait, les matières primaire 7 et secondaire 8 sont d'ores et déjà présentes sur la cigarette 1 , l'utilisateur n'ayant pas à conserver en main le paquet ou un élément contenant la matière secondaire, contrairement à la plupart des solutions connues de l'art antérieur. Lorsque l'utilisateur achète un paquet, chaque cigarette est déjà pourvue de son propre réceptacle 9, ce qui permet de limiter au minimum la quantité de matière secondaire utilisée. Le réceptacle 9 peut avoir une forme cylindrique, sphérique, parallélépipédique, ou autre, et être réalisé en papier, carton préférentiellement plastifié, en plastique, en caoutchouc, en matériau ouaté ou « expansé » du type utilisé pour la fabrication des filtres de cigarette, etc. Il peut avoir une ou plusieurs extrémités ouvertes vers l'extérieur ou être totalement fermé. En pratique, le réceptacle 9 se présente sous la forme d'un tube cylindrique, préférentiellement fermé à l'une de ses extrémités 19 et dont le diamètre extérieur correspond sensiblement à celui de la cigarette 1. Le diamètre du réceptacle 9 peut par exemple varier de 2 mm à 8 mm. Sa longueur peut varier de quelques millimètres à quelques centimètres. Pour des raisons de sécurité, il est avantageux que la matière secondaire 8 ne puisse pas rentrer accidentellement en contact avec la matière primaire 7. Pour cette raison, le réceptacle 9 est avantageusement initialement positionné, préférentiellement fixé, à l'extrémité d'inhalation 5, c'est-à-dire éloigné de la matière primaire 7. La mise en contact des deux matières chimiques ne peut donc être que volontaire. Avant cet acte, la matière primaire 7 est physiquement isolée de la matière secondaire 8. The chemical reaction initiated by this couple of chemical materials is not instantaneous, a small incubation period of a few seconds being necessary, without this leading the user to believe that the cigarette has not been lit. The reaction is announced by a prior release of non-toxic smoke consisting only of carbon dioxide and water vapor. The reaction is not too intense, the effect being similar to that caused by the flame of a lighter or a match. Once the reaction is complete, the end 4 of the cigarette is sufficiently lit to allow time for the smoker to carry the cigarette to his lips and begin to suck tobacco smoke assuring that it will not suck the smoke from the incompatibility reaction. This state of affairs secures the self-ignition of the cigarette 1 and reassures the user. In addition, these two chemical materials are sufficiently stable to ensure a sufficient duration of use over time. To make available to the user, in a single operation, all that he needs to light his cigarette as soon as he extracts it from the package, the secondary material 8 is contained in a receptacle 9 initially disposed of. one end of the cigarette, in an arrangement preventing any contact of said secondary material with the primary material 7. This receptacle 9 is removable, and configured to position against the end to ignite 4, in an arrangement allowing the setting in contact with the secondary material 8 with the primary material 7. In practice, the secondary material 8 is disposed in a removable receptacle 9 configured to engage at the end to ignite 4. By "sticking" is meant in the sense of the present invention, the possibility that the receptacle 9 to be positioned on, against and / or around the end to ignite 4, with the possibility of remaining or not to fix at said end. As a result, the primary 7 and secondary 8 materials are already present on the cigarette 1, since the user does not have to keep in his hand the package or an element containing the secondary material, contrary to most of the solutions. known from the prior art. When the user purchases a package, each cigarette is already provided with its own receptacle 9, which allows to minimize the amount of secondary material used. The receptacle 9 may have a cylindrical, spherical, parallelepipedal, or other shape, and be made of preferably plasticized paper, cardboard, plastic, rubber, wadded or "expanded" material of the type used for the manufacture of cigarette filters, etc. It may have one or more open ends to the outside or be completely closed. In practice, the receptacle 9 is in the form of a cylindrical tube, preferably closed at one of its ends 19 and whose outer diameter substantially corresponds to that of the cigarette 1. The diameter of the receptacle 9 may for example vary from 2 mm to 8 mm. Its length can vary from a few millimeters to a few centimeters. For safety reasons, it is advantageous for the secondary material 8 not to accidentally come into contact with the primary material 7. For this reason, the receptacle 9 is advantageously initially positioned, preferably fixed, at the inhalation end 5 , that is to say remote from the primary material 7. The bringing into contact of the two chemical materials can therefore only be voluntary. Prior to this act, the primary material 7 is physically isolated from the secondary material 8.
Selon un premier mode de réalisation représenté sur les figures 7a et 7b, le réceptacle 9 comprend une zone de fixation 1 1 configurée pour s'emmancher sur l'extrémité d'inhalation 5 et sur l'extrémité à allumer 4. Cette zone de fixation 1 1 se présente sous la forme d'une portion cylindrique qui est opposée à l'extrémité fermée 19 du tube formant le réceptacle 9. Un opercule d'étanchéité frangible 10 forme le fond de la zone de fixation 1 1 , la matière secondaire 8 étant disposée entre ledit opercule et l'extrémité fermée 19 du réceptacle 9. L'autre extrémité de la zone de fixation 1 1 est ouverte de façon à permettre son emmanchement sur l'extrémité à allumer 4. La zone de fixation 1 1 a un diamètre intérieur égal ou supérieur (par exemple de 0,1 mm à 1 mm), au diamètre externe de la cigarette 1 , et une longueur pouvant varier de 3 mm à 10 mm. Lorsque le réceptacle 9 est initialement emmanché sur l'extrémité d'inhalation 5, un ou deux points de colle peuvent être prévus dans la zone de fixation 1 1 de façon à éviter toute séparation intempestive. According to a first embodiment shown in FIGS. 7a and 7b, the receptacle 9 comprises a fastening zone 1 1 configured to slide on the inhalation end 5 and on the end to be ignited 4. This fastening zone 1 1 is in the form of a cylindrical portion which is opposite to the closed end 19 of the tube forming the receptacle 9. A frangible seal 10 forms the bottom of the attachment zone 1 1, the secondary material 8 being disposed between said lid and the closed end 19 of the receptacle 9. The other end of the attachment zone 1 1 is open so as to allow it to fit onto the end to be ignited 4. The attachment zone 1 1 has a internal diameter equal or greater (for example from 0.1 mm to 1 mm), the outer diameter of the cigarette 1, and a length that can vary from 3 mm to 10 mm. When the receptacle 9 is initially fitted on the inhalation end 5, one or two points of glue may be provided in the attachment zone 1 1 so as to avoid any inadvertent separation.
Dans une variante de réalisation représentée sur les figures 8a et 8b, le réceptacle 9 est sécable de manière à permettre une manipulation indépendante de la cigarette 1 et dudit réceptacle. La fixation initiale du réceptacle sur l'extrémité d'inhalation de la cigarette, combinée au caractère sécable dudit réceptacle pour le manipuler, offre une grande sécurité. En effet, les risques de détachement accidentel du réceptacle et de sa mise en contact avec la matière primaire d'allumage, sont ainsi considérablement limités. En pratique, un filtre 6 est fixé par un emballage 12 sur l'extrémité d'inhalation 5 de la cigarette 1. Cet emballage 12 se présente généralement sous la forme d'une feuille de papier dont une partie est enroulée autour de l'extrémité d'inhalation 5 et une autre partie est enroulée autour du filtre 6. L'emballage 12 est généralement scellé par collage. Le réceptacle 9 se présente alors sous la forme d'un tube cylindrique initialement fixé à l'extrémité d'inhalation 5, dans le prolongement du filtre 6. L'emballage 12 assure alors la fixation du tube cylindrique formant le réceptacle 9 sur le filtre 6. La feuille de papier formant l'emballage 12 a une longueur choisie pour s'enrouler autour : de l'extrémité d'inhalation 5, du filtre 6 et du tube formant réceptacle 9. En pratique, l'emballage 12 peut comprendre une partie fragile 13 au niveau de la jonction du filtre 6 et du réceptacle 9, permettant de détacher manuellement ledit réceptacle par traction, flexion torsion ou rotation. Cette partie fragile 13 peut par exemple consister en une zone de moindre épaisseur ou en des perforations réalisées sur l'emballage 12, au niveau de la jonction du filtre 6 et du réceptacle 9. En pratique, le réceptacle 9 comprend une zone de fixation 1 1 configurée pour s'emmancher sur l'extrémité à allumer 4. Cette zone de fixation 1 1 se présente sous la forme d'une portion cylindrique qui est opposée à l'extrémité fermée 19 du tube formant le réceptacle 9. Un opercule d'étanchéité frangible 10 forme le fond de la zone de fixation 1 1 , la matière secondaire 8 étant disposée entre ledit opercule et l'extrémité fermée 19 du réceptacle 9. L'autre extrémité de la zone de fixation 1 1 est ouverte de façon à permettre son emmanchement sur l'extrémité à allumer 4. La zone de fixation 1 1 a un diamètre intérieur égal ou supérieur (par exemple de 0,1 mm à 1 mm), au diamètre externe de la cigarette 1 , et une longueur pouvant varier de 3 mm à 10 mm. In an alternative embodiment shown in Figures 8a and 8b, the receptacle 9 is breakable so as to allow independent handling of the cigarette 1 and said receptacle. The initial attachment of the receptacle on the inhalation end of the cigarette, combined with the breakable character of said receptacle for handling, provides great security. Indeed, the risk of accidental detachment of the receptacle and its contact with the primary ignition material, are thus considerably limited. In practice, a filter 6 is fixed by a package 12 on the inhalation end 5 of cigarette 1. This package 12 is generally in the form of a sheet of paper some of which is wound around the inhalation end 5 and another part is wrapped around the filter 6. The package 12 is generally sealed by gluing. The receptacle 9 is then in the form of a cylindrical tube initially fixed to the inhalation end 5, in the extension of the filter 6. The packaging 12 then ensures the attachment of the cylindrical tube forming the receptacle 9 on the filter 6. The sheet of paper forming the package 12 has a length chosen to wrap around: the inhalation end 5, the filter 6 and the receptacle tube 9. In practice, the package 12 may comprise a fragile portion 13 at the junction of the filter 6 and the receptacle 9, for manually detaching said receptacle by traction, bending or twisting rotation. This fragile portion 13 may for example consist of a zone of lesser thickness or perforations made on the package 12, at the junction of the filter 6 and the receptacle 9. In practice, the receptacle 9 comprises a fastening zone 1 1 configured to engage on the end to ignite 4. This fastening area 1 1 is in the form of a cylindrical portion which is opposite to the closed end 19 of the tube forming the receptacle 9. A cover of frangible sealing 10 forms the bottom of the fastening area 1 1, the secondary material 8 being disposed between said cap and the closed end 19 of the receptacle 9. The other end of the fastening area 1 1 is opened so as to allow The fixing zone 11 has an internal diameter equal to or greater than (for example 0.1 mm to 1 mm), the external diameter of the cigarette 1, and a length which may vary from 3 mm to 10 mm.
En l'absence de filtre 6, le réceptacle 9 se présente toujours sous la forme d'un tube cylindrique initialement positionné, préférentiellement fixé, à l'extrémité d'inhalation 5, dans le prolongement de cette dernière. L'emballage 12, préférentiellement doté d'une partie fragile 13, assure la fixation directe du réceptacle 9 sur l'extrémité d'inhalation 5. La mise en place du réceptacle 9 se fait ainsi de la même manière que celle d'un filtre sur les cigarettes qui en sont dotées. In the absence of filter 6, the receptacle 9 is always in the form of a cylindrical tube initially positioned, preferably fixed, at the inhalation end 5, in the extension thereof. The package 12, preferably with a fragile portion 13, ensures the direct attachment of the receptacle 9 on the inhalation end 5. The establishment of the receptacle 9 is in the same way as that of a filter on the cigarettes that have them.
Sur les figures 1 , 2, 7a et 8a, le réceptacle 9 est initialement positionné au niveau de l'extrémité d'inhalation 5 de la cigarette 1. On peut toutefois prévoir que le réceptacle 9 soit initialement positionné au niveau de l'extrémité à allumer 4. Ce troisième mode de réalisation est illustré par les figures 9a et 9b. Le réceptacle 9 comprend deux zones de fixation 1 1 a et 1 1 b, chacune configurée pour s'emmancher sur l'extrémité à allumer 4. Ces zones de fixation 1 1 a, 1 1 b se présentent sous la forme de portion cylindrique. La première zone de fixation 1 1a est étanche vis-à-vis de la matière secondaire 8 et située dans le prolongement de l'extrémité fermée 19 du réceptacle 9, tandis que la seconde zone de fixation 1 1 b est opposée à ladite extrémité fermée. In FIGS. 1, 2, 7a and 8a, the receptacle 9 is initially positioned at the inhalation end 5 of the cigarette 1. However, it is possible for the receptacle 9 to be initially positioned at the end of the cigarette. 4. This third embodiment is illustrated by FIGS. 9a and 9b. The receptacle 9 comprises two attachment zones 1 1 a and 1 1 b, each configured to engage on the end to ignite 4. These attachment areas 1 1 a, 1 1 b are in the form of a cylindrical portion. The first fastening area January 1a is sealed vis-à-vis the secondary material 8 and located in the extension of the closed end 19 of the receptacle 9, while the second fastening area January 1 is opposite to said closed end .
L'extrémité fermée 19 du réceptacle 9 forme le fond de la première zone de fixation 1 1 a, cette dernière étant de fait étanche. La matière primaire 7 peut ainsi être initialement physiquement isolée de la matière secondaire 8. L'autre extrémité de la première zone de fixation 1 1a est ouverte de façon à permettre son emmanchement sur l'extrémité à allumer 4.  The closed end 19 of the receptacle 9 forms the bottom of the first fastening area January 1, the latter being in fact sealed. The primary material 7 can thus be initially physically isolated from the secondary material 8. The other end of the first attachment zone 1 1a is open so as to allow it to fit onto the end to be ignited 4.
Un opercule d'étanchéité frangible 10 forme le fond de la seconde zone de fixation 1 1 b, la matière secondaire 8 étant disposée entre ledit opercule et l'extrémité fermée 19 du réceptacle 9. L'autre extrémité de la seconde zone de fixation 1 1 b est ouverte de façon à permettre son emmanchement sur l'extrémité à allumer 4.  A frangible seal 10 forms the bottom of the second attachment zone 1 1b, the secondary material 8 being disposed between said seal and the closed end 19 of the receptacle 9. The other end of the second attachment zone 1 1 b is open so as to allow its fitting on the end to ignite 4.
Les zones de fixation 1 1 a, 1 1 b ont un diamètre intérieur égal ou supérieur (par exemple de 0,1 mm à 1 mm), au diamètre externe de la cigarette 1 , et une longueur pouvant varier de 3 mm à 10 mm. La première zone de fixation 1 1 a est initialement emmanchée sur l'extrémité à allumer 4 (figure 9a). Un ou deux points de colle peuvent être prévus de façon à éviter toute séparation intempestive. Pour mettre en contact la matière secondaire 8 avec la matière primaire 7, il suffit de retourner le réceptacle 9 et d'emmancher la seconde zone de fixation 1 1 b sur l'extrémité à allumer 4 (figure 9b). En lieu et place, ou en complément, de la première zone de fixation 1 1a il est possible de prévoir un réceptacle 9 sécable, similaire à celui décrit précédemment pour le second mode de réalisation et schématisé sur les figures 8a et 8b, mais initialement fixé sur l'extrémité à allumer 4. The attachment zones 11a, 11b have an inner diameter equal to or greater than (for example 0.1 mm to 1 mm), the outer diameter of the cigarette 1, and a length that can vary from 3 mm to 10 mm. . The first attachment zone January 1 is initially fitted on the end to ignite 4 (Figure 9a). One or two points of glue can be provided to avoid any inadvertent separation. To bring the secondary material 8 into contact with the primary material 7, it is sufficient to turn the receptacle 9 and press the second attachment area 1 1b on the end to ignite 4 (Figure 9b). Instead of, or in addition to, the first attachment area 1 1a it is possible to provide a breakable receptacle 9, similar to that described above for the second embodiment and shown diagrammatically in FIGS. 8a and 8b, but initially fixed on the end to light 4.
La matière secondaire 8 peut être directement introduite dans le réceptacle 9 lorsqu'elle est sous forme solide, de gel ou crémeuse. Lorsqu'elle est sous forme fluide, un matériau spongieux du type éponge peut être inséré dans le réceptacle 9, de façon à contenir ladite matière secondaire 8, une simple pression sur ledit matériau spongieux permettant de libérer ladite matière secondaire. The secondary material 8 can be directly introduced into the receptacle 9 when it is in solid, gel or creamy form. When in a fluid form, a spongy material of the sponge type can be inserted into the receptacle 9, so as to contain said secondary material 8, a simple pressure on said spongy material for releasing said secondary material.
Elle peut également être initialement conditionnée dans une ou plusieurs gélules ou capsules, elles-mêmes agencées ultérieurement dans le réceptacle 9. Dans une telle configuration avec gélules, le réceptacle 9 comporte préférentiellement une ou plusieurs parois flexibles permettant de rompre lesdites gélules par écrasement lorsqu'un effort de pression latérale (perpendiculaire à l'axe de la cigarette) ou longitudinale (dans l'axe de la cigarette) est exercé sur ladite ou lesdites parois flexibles.  It may also be initially packaged in one or more capsules or capsules, themselves subsequently arranged in the receptacle 9. In such a configuration with capsules, the receptacle 9 preferably comprises one or more flexible walls for breaking said capsules by crushing when a lateral pressure force (perpendicular to the axis of the cigarette) or longitudinal (in the axis of the cigarette) is exerted on said flexible wall or walls.
Pour éviter que la matière secondaire 8 ne s'échappe du réceptacle 9, ce dernier peut être fermé par un opercule d'étanchéité frangible 10 réalisé en papier, en matière plastique, en aluminium, etc. Une simple pression de l'extrémité à allumer 4 sur cet opercule 10 permet de l'ouvrir et de libérer la matière secondaire 8. En pratique, la matière secondaire 8 étant destinée à sortir du réceptacle 9 depuis la zone de fixation 1 1 , l'opercule d'étanchéité frangible 10 est situé au niveau de cette zone.  To prevent the secondary material 8 from escaping the receptacle 9, the latter can be closed by a frangible seal 10 made of paper, plastic, aluminum, etc. A simple pressure of the end to ignite 4 on the cover 10 allows to open and release the secondary material 8. In practice, the secondary material 8 is intended to exit the receptacle 9 from the attachment zone 1 1, l Frangible seal 10 is located at this zone.
D'autres solutions techniques peuvent toutefois être envisagées. La matière primaire 7 peut par exemple être placée dans un petit réceptacle dont les parois sont configurées (par exemple micro-perforée) pour laisser passer au travers une matière secondaire 8 fluide. Cette solution présente l'avantage de pouvoir conserver une matière primaire 7 à l'état pulvérulent, sans traitement préalable susceptible de changer ses caractéristiques cristallines. De même, on peut imaginer que la matière primaire 7 soit déposée par saupoudrage sur un papier recouvert d'un adhésif sur lesquels les particules de ladite matière primaire se collent. L'adhésif chargé de particules de matière primaire 7 est ensuite enroulé autour de l'extrémité à allumer 4 de la cigarette 1. Other technical solutions can however be envisaged. The primary material 7 may for example be placed in a small receptacle whose walls are configured (for example micro-perforated) to pass through a secondary material 8 fluid. This solution has the advantage of being able to keep a primary material 7 in the powdery state, without prior treatment likely to change its crystalline characteristics. Similarly, it is conceivable that the primary material 7 is deposited by dusting on a paper covered with an adhesive on which the particles of said primary material stick. The adhesive loaded with particles of primary material 7 is then wound around the end to ignite 4 of the cigarette 1.
Le papier cigarette lui-même peut également intégrer une bande adhésive du côté de l'extrémité à allumer 4 de la cigarette 1 : le papier est préalablement chargé de particules de matière primaire 7 et utilisé comme tel avant chargement en tabac de la cigarette 1. Les figures 1 à 6 illustrent comment un fumeur peut allumer sa cigarette avec des gestes simples, qu'il tienne ladite cigarette dans une main ou la porte non encore allumée à sa bouche.  The cigarette paper itself can also incorporate an adhesive tape on the side of the end 4 of cigarette 1 to light: the paper is previously loaded with particles of primary material 7 and used as such before tobacco loading of the cigarette 1. Figures 1 to 6 illustrate how a smoker can light his cigarette with simple gestures, whether he holds the cigarette in a hand or the door not yet lit to his mouth.
Selon le premier mode (figures 7a et 7b) et le second mode de réalisation (figures 8a et 8b) le réceptacle 9 est initialement fixé à l'extrémité d'inhalation 5 opposée à l'extrémité à allumer 4 de la cigarette 1 , pour que la matière chimique secondaire 8 soit physiquement séparée de la matière chimique primaire 7 (figure 1 ). L'utilisateur sépare le réceptacle 9 de l'extrémité d'inhalation 5 (figure 2) et le positionne en vis-à-vis de l'extrémité à allumer 4 (figure 3). Le réceptacle 9 est alors mis en contact avec l'extrémité à allumer 4 de façon à ce que la matière secondaire 8 vienne humecter la matière primaire dont est enduite l'extrémité à allumer 4 (figure 4). Lorsque le réceptacle 9 est fermé, l'utilisateur peut mettre en contact la matière secondaire 8 avec la matière primaire 7 en écrasant ledit réceptacle (figure 5). Lorsque le réceptacle 9 est refermé par un opercule d'étanchéité frangible 10, l'utilisateur peut mettre en contact la matière secondaire 8 avec la matière primaire 7 en perçant ledit opercule au moyen de l'extrémité à allumer 4. Lorsque le réceptacle 9 est ouvert vers l'extérieur, l'utilisateur peut mettre en contact la matière secondaire 8 avec la matière primaire 7 en enfonçant directement l'extrémité à allumer 4 de la cigarette 1 à l'intérieur dudit réceptacle. Une fois que la matière secondaire 8 est en contact avec la matière primaire 7, l'utilisateur retire le réceptacle 9 de l'extrémité à allumer 4 (figure 6). La réaction s'initie et l'extrémité à allumer 4 s'enflamme. According to the first embodiment (FIGS. 7a and 7b) and the second embodiment (FIGS. 8a and 8b), the receptacle 9 is initially attached to the inhalation end 5 opposite to the igniter end 4 of the cigarette 1, so that the secondary chemical substance 8 is physically separated from the primary chemical material 7 (FIG. 1). The user separates the receptacle 9 from the inhalation end 5 (FIG. 2) and positions it vis-à-vis the end to be ignited 4 (FIG. 3). The receptacle 9 is then brought into contact with the end to ignite 4 so that the secondary material 8 comes to moisten the primary material which is coated with the end to ignite 4 (Figure 4). When the receptacle 9 is closed, the user can contact the secondary material 8 with the primary material 7 by crushing said receptacle (Figure 5). When the receptacle 9 is closed by a frangible sealing cap 10, the user can bring the secondary material 8 into contact with the primary material 7 by piercing said cap by means of the end to be ignited 4. When the receptacle 9 is open to the outside, the user can bring the secondary material 8 into contact with the primary material 7 by directly pressing the end to ignite 4 of the cigarette 1 inside said receptacle. Once the secondary material 8 is in contact with the primary material 7, the user removes the receptacle 9 from the end to ignite 4 (Figure 6). The reaction is initiated and the end to ignite 4 ignites.
Selon le troisième mode de réalisation (figures 9a et 9b), on commence par désoperculer le réceptacle 9 sur sa partie libre qui n'est pas en contact avec l'extrémité à allumer 4. On rompt ensuite la liaison réceptacle 4/cigarette 1 , puis on retourne ledit réceptacle de façon à emmancher la seconde zone de fixation 1 1 b contre l'extrémité à allumer 4. Il suffit alors d'exercer une pression sur le réceptacle 4 pour le vider de sa matière secondaire 8 et initier la réaction. According to the third embodiment (FIGS. 9a and 9b), the receptacle 9 is first uncapped on its free part which is not in contact with the end to be ignited. The receptacle 4 / cigarette 1 is then broken. then it returns said receptacle so as to press the second fastening area 1 1b against the end to ignite 4. It is then sufficient to exert pressure on the receptacle 4 to empty its secondary material 8 and initiate the reaction.
