Description

FIELD OF THE INVENTION [0001] The present invention relates to devices for self-ignition of cigarettes, including incompatible chemicals that produce sufficient thermal energy to ignite the ends of the cigarette when in contact with each other. BACKGROUND OF THE INVENTION [0002] TO LIGHT THE END OF SAID CIGARETTE WHEN THEY ARE CONTACT WITH ONE ANOTHER}

The invention relates to an apparatus for self-ignition of a cigarette comprising immiscible chemicals which produce sufficient thermal energy to ignite the end of the cigarette when in contact with each other.

This relates to pyrotechnic devices, in particular to fire devices for igniting cigarettes and providing alternatives to conventional means in the form of lighters or matches.

Devices for self-igniting cigarettes 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 GB 304 145 (Piedad and Alejandro LIFCHUZ), FR 709 175 (Giulio TURRI), JP 2005 5 224 232 (ISHIKAWA JOJI), GB 406 153 (YOO, BYUNG EON) FR 7 539 535 (TOKYO ENGINEERING CO. (Ansley HERMAN FOX). These devices include a priming material arranged to ignite a combustible material under the influence of impact or friction. Commonly used contact strips wear as the cigarettes ignite. Further, when the belt is worn more, it becomes difficult to ignite the cigarette.

BE 1 012 826 (JACQUET), BE 1 015 826 (JACQUET), BE 97 941 (BONCHEV MIROSLAV B.), GB 356 861 (Robert SUTHERLAND), GB 2 342 560 (ZYGMUNT) (ABISDID et al.), Which is located at the ignition end of the cigarette, has a first end positioned at the ignition end of the cigarette, Describes devices for self-ignition comprising a chemical substance and a second chemical substance immiscible with the first substance. These devices use the principle of incompatibility of spontaneously igniting chemicals when placed in contact with the other end. Indeed, the second chemical is:

- conditioned on one of the sides of the pack of cigarettes in such a way that when the pack is manipulated the second chemical is separated and as a result it is practically impossible to subsequently ignite the cigarettes,

- or is applied conditionally in individual containers which are rarely applied.

In order to overcome these imperfections, a device for self-ignition is known from US 3 109 435 (PALEY) in which potassium permanganate is located in a capsule made of a porous material fixed at the ignition end of the cigarette. A second chemical is fit on the ignition end of the cigarette and the second material is placed in contact with the first material. This device is relatively realistic and has drawbacks. As a result, the second material for ignition absorbs the absorbing material located inside the vessel. After aging for several days in ambient conditions (especially in the moisture content of the air), the second material is oxidized and / or dried in such a way that it is difficult to ignite the cigarettes in a reliable manner. The properties of the potassium hydroxide are also deteriorated by the humidity contained in the air and the tobacco of the cigarette. The use of capsules to include permanganate also introduces additional materials which can lead to the addition of slag, which can be a significant disadvantage in terms of smokers unless properly selected. US 3 109 435 does not have access to the properties of the material of the capsule. WO 2012/123679 (ABISDID et al.) Considers encapsulating the first substance, but does not reveal the properties of the capsule.

In view of the foregoing prior art, it is an object of the present invention to provide an apparatus which enables easy ignition of a cigarette while eliminating the drawbacks associated with the application of chemicals known in the prior art.

The present invention also aims to provide an apparatus for self-ignition which is easy to use, simple design and low cost.

The solution proposed by the present invention is a cigarette comprising a first chemical and a second chemical, said chemicals being incompatible and producing sufficient thermal energy to ignite the end of the cigarette when they come into contact with each other, For self-ignition. The first chemical is located within the capsule intended to be fixed to the igniting end of the cigarette. The second chemical is located in a receptacle designed to be located at the ignition end of the cigarette in an arrangement that allows it to come into contact with the first material.

The device is characterized in that the capsule is made of a combustible material that is both airtight and moisture-tight, the capsule has at least one puncturing zone, and the rdeceptacle is a sealed Wherein the reservoir contains a pointed end piece that allows the second chemical to flow with sufficient strength to puncture the puncture region of the capsule .

The use of capsules made of airtight and moisture-proof materials makes it possible to protect the first chemical from air and humidity contained in the cigarettes of the cigarette. In addition, the selection of a combustible material for such a capsule makes it possible to facilitate the ignition of the cigarette if the smoker wants to use conventional ignition means such as matches, lighters, or other cigarettes.

The use of such receptors makes it possible to carefully deposit the second chemical for the first chemical, avoiding chemical wetting and preventing self-ignition reactions or at least generating sufficient thermal energy to ignite the cigarette Make it slow to the point where it does not exist.

The selection of the capsule material and the design of the receptor thus act synergistically, thus providing effective ignition of the cigarettes after a relatively long aging time.

Apart from the distinct characteristics defined above, other distinctive features of the subject device of the present invention are listed below, which may be considered individually or in combination:

The puncture area may have a sealing form that is thinner and / or less resistant than the rest of the wall of the capsule,

The capsule is advantageously composed mostly of nitrocellulose,

The capsule advantageously retains the nitrocellulose collodion in an intermediary position at the ignition end of the cigarette,

The receptacle advantageously has the shape of a cylindrical tube whose outer diameter corresponds substantially to the outer diameter of the cigarette and which is accompanied by a storage vessel which is accommodated in the tube and which comprises a flexible filling material flexible filling material,

Receptors, storage vessels and flexible packing materials are advantageously made of biodegradable and / or bio-fragmentable materials,

The receptors and storage containers are advantageously made of a flexible material such that the pressure on the walls of the receptacle causes the second chemical to exit through the peak,

In an alternative embodiment, a piston is provided in the storage vessel such that displacement of the piston causes the second chemical to exit through the peak,

The storage container comprises from 0.005 ml to 0.05 ml of liquid glycerin,

- the first chemical consists primarily of potassium permanganate in the form of a powder having a granulometry of from 10 탆 to 200 탆, advantageously from 20 탆 to 30 탆,

A portion of the capsule is advantageously configured to function as a guide of the receiver while fitting said receptacle to the igniting end of the cigarette,

The capsule is formed in a tapered shape such that a widest portion of the capsule is located on the side of the cigarette which is to be ignited,

The capsule may include a portion that functions as a guide for the receptor while fitting the receptor to the ignition end of the cigarette. The portion forming this guide may be used to impart a more appropriate shape to the first material so that the first material contacts the second material. As a result, depending on the type of contact between the first and second materials, ignition can be performed better. Best results are obtained when the contact is made at the surface of the first material or confined to the first layers, especially when the first material is potassium permanganate and the second material is liquid glycerin.

The first chemical is primarily composed of potassium permanganate and the second chemical is mostly composed of glycerin,

- The sealed vessel and peaks can have the form of a single-block part obtained by molding or can consist of two separate parts.

Another aspect of the present invention relates to a cigarette comprising an inhalation end and an end to be ignited, said cigarette having a device for self-ignition according to one of the above characteristics, A container is initially arranged to one of the ends of the cigarette to prevent any contact with the cigarette, the container being removable and positioned at the end to be ignited in an arrangement permitting contact of the second material with the first material .

Apart from the distinct characteristics defined above, other distinctive features of the subject device of the present invention are listed below, and these features may be considered individually or in combination:

- the receptacle advantageously comprises a fastening zone arranged around the tip of the pin, said fixed zone comprising:

- fitting on the opposite suction end in the end to be ignited of the cigarette in such a way that said peak piece is embedded into said suction end,

- fit to the end to be ignited in such a way that the peak piece is embedded into the capsule,

- the receptor is selected from the group consisting of:

A first anchoring region disposed about the peak and configured to be fitted on an end to be ignited in such a manner as to cause the peak to be embedded into the capsule;

And - a second securing region adapted to fit on the end to be ignited or on the suction end in such a way that the peaks are separated from the capsule, opposite the first region.

- the receptors are accompanied by peaks that are embedded into the suction end of the cigarette and are retained in the extension of the cigarette by a detachable adhesive tab of the perforations along the dashed line (or by any other similar fastening means) .

The present invention makes it possible to self-ignite the cigarette (1). "Cigarette" means any conventional cigarette, cigarillo, cigar, or other similar thing that can be consumed by smoking cigarettes, with or without a filter. As shown in the accompanying drawings, the cigarette 1 is generally formed of paper 2 and has a cylindrical shape in which a finely divided tobacco leaf 3 is disposed. The diameter may be within the range of 3 mm to 7 mm, and the length may vary between 60 mm and 100 mm. Which comprises an end 4 to be ignited and a suction end 5 opposite the end to be ignited. The suction end 5 may in particular comprise a filter 6.

An apparatus for self-ignition which is a subject of the present invention comprises a first chemical 7 (or "to be lit" material) and a second chemical 8 (or "for lighting" material ). These two chemicals are incompatible and generate sufficient thermal energy (e.g., 150 ° C to 700 ° C) to ignite the end 4 of the cigarette 1, with or without flame, when in contact with each other do.

The first material 7 / second material 8 pair may be, for example, potassium permanganate / glycol; Silver nitrate / red phosphorus; Silver nitrate / sulfur; Chlorates and boric acid / glycol; Aluminum / tincture of iodine; Sodium metal or other metals of the same family / water or alcoholic termination reactants; Raney nickel or phosphoric / oxidizer materials (MnO ₂ )); It may be an oxidant / fuel pair in the form of nitrocellulose / strong acid (sulfuric acid, hydrochloric acid).

Best results are obtained with a first chemical consisting mostly of potassium permanganate and a second chemical mostly composed of glycerin. In view of the present invention, a "most (mostly)" is the second material (8) to separate a first material (7) to separate the glycerin to the total weight of the wt% of potassium permanganate 50% by weight / weight of _{the first or} of the _the means that _{two substances} or more, advantageously 70% by weight / weight of _{the first or second material} or more, preferably 95% by weight / weight of _{the first or the second material} and above. Moreover, these pairs of substances have the advantage of following sanitary standards in effect and without any risk of toxicity. As a result, glycerin is a product commonly used as a food additive; It has the form of a viscous, transparent, colorless, odorless non-toxic liquid with sweetness. Potassium permanganate is an inorganic salt conventionally used as a disinfectant and as a deodorant. This is especially used to treat drinking water.

The reaction between potassium permanganate and glycerin is a surface chemical reaction. That is, the reaction kinetics are directly proportional to the magnitude of the contact area between solid (potassium permanganate) and liquid (glycerin). Potassium permanganate is preferably used in a relatively fine powder form. The finer the powder, the larger the contact area between the solid (potassium permanganate) and the liquid (glycerin) and the faster the reaction rate. The best reactivity (initiation of reaction in a few seconds) is obtained with a fine powder of potassium permanganate having a granule size of 10 탆 to 200 탆, advantageously 20 탆 to 30 탆. An average granule size of 25 mu m provides good results.

Since a short incubation period of several seconds is required, the chemical reaction initiated by the first chemical 7, mostly composed of potassium permanganate and the second chemical 8 mostly composed of glycerin, is not immediate, Does not allow the cigarette 1 to feel that it has not been ignited. The reaction is known by the preceding emissions of non-toxic smoke consisting entirely of carbon dioxide and water vapor. Since the effect is similar to that caused by the flame of a lighter or match, the reaction is not intense. Once the reaction is complete, by ensuring that the end 4 of the cigarette is sufficiently ignited so that the smoker does not inhale the smoke of the incomplete reaction, the smoker takes the cigarette to its slips and inhales the cigarette smoke Allow enough time to start. This state guarantees self-ignition of the cigarette 1 and reassures the user. In addition, these two chemicals are sufficiently stable for a sufficient period of time.

Separate materials may be used to dilute, bind, immobilize, activate, or reverse delay or passivate the raw immiscible chemicals performed in the present invention. In particular, by the addition of sodium thiosulfate to the permanganate salt, significant improvements were observed in the reactivity of the permanganate with glycerin and in the reproducibility in the ignition time. In addition, other materials (e.g., waterproofing materials) may be able to enhance the resistance of the first material 7 and the second material 8 to ambient conditions, especially humidity.

6A to 6H, a first chemical 7 is intended to be located in the capsule 70 and to be fixed to the ignition end 4 of the cigarette 1. The capsule 70 may be positioned at the very edge (Figures 6a-6g) or slightly retracted (Figure 6h) of the end 4 to be ignited. In the latter case, as shown in FIG. 6h, the capsule 70 can be covered with the tobacco fibers in such a way that the end 4 to be ignited over a depth of a few millimeters maintains an aspect ratio similar to that of a normal cigarette. have. In practice, the capsule 70 comprises 0.1 mg to 5 mg potassium permanganate. The capsule 70 is mostly composed of nitrocellulose, i.e. the weight% of the nitrocellulose relative to the total weight of the capsule (not filled with the first substance 7) is greater than 50 wt% / weight _capsule , advantageously greater than 70 wt% / Weight _capsule or more, preferably 95 weight% / weight _capsule or more. In practice, the capsules are formed from a sheet of nitrocellulose, for example Nitrofilm (R) or celluloid. Nitrocellulose has many advantages:

This material is airtight and watertight and makes it possible to protect the first chemical 7 against moisture contained in the air and in the cigarette of the cigarette 1;

- combustion of nitrocellulose discharges only gaseous species without creating solid residues or leaving only very small amounts of slag or ashes;

- Burning time is very fast, less than 1 second or less. Thus, since the smoking article has the total time required for the capsule 70 to burn before the cigarette is brought to his mouth, the smoking article has no risk of inhaling the combustion products,

- The predetermined formatting of the capsule 70 is easy.

The selection of this material also has the advantage of facilitating the industrial production of the objective cigarettes of the present invention: on the one hand, the capsules 70 can be pre-filled and, according to an industrial process which is easy to automate, And on the other hand fixing the capsule 70 to the end 4 of the cigarette 1 is also a purely mechanical operation which can be easily automated and is very important to the tobacco company.

Other materials suitable for those skilled in the art having properties similar to those of nitrocellulose can be used, for example pongee silk or biodegradable pongee.

When the first chemical 7, which is mostly potassium permanganate, is in contact with a second chemical, which is mostly glycerine, the mixtures are heated quickly to as many as a hundred as possible without entrapping smoke. Subsequently, this thermal energy is transferred to nitrocellulose having a self-ignition temperature of 150 ° C to 200 ° C. Thus, this "activation" material is ignited as soon as the self-ignition temperature is reached.

The end 4 to be ignited of the cigarette 1 may be previously impregnated with a colloid of nitrocellulose before the capsule 70 is placed. This deposition enhances the certainty of the transfer of the flame produced by the reaction of the two incompatible materials 7 and 8 to the tobacco leaves and increases the holding of the capsule 70 in place on the firing end 4 It is especially interesting to make. For example, in an industrial manufacturing, the preceding deposition material can be applied to the cigarette 1 of the capsule 70 containing the first chemical 7 once it has been dried, and may have the form of glue-gel. The capsule 70 may also be glued on the end 4 by gum arabic, a food-grade adhesive or any other article suitable for those skilled in the art .

Referring to Figs. 5A, 5B and 5C, the second chemical 8 is located within the receptacle 80. Fig. In the embodiment shown in Figures 5a and 5b the receptacle 80 is fitted on the ignition end 4 of the cigarette 1 and is configured to contact the second material with the first material 7. [ In the sense of the present invention, the term "fitting" is used to mean that the receptacle 80 is provided on the end 4 to be ignited, with or without the remainder being fixed to the end, As shown in FIG. In the embodiment shown in Figure 5c, the receptacle 80 is more generally positioned relative to the end 4 to be ignited in an arrangement that allows the second material 8 to be in contact with the first material 7. [ .

The receptor 80 is removable, i. E. It can be separated from the cigarette 1. It may have one or more ends open to the outside or may be completely closed. In practice, the receptacle 80 preferably has the shape of a cylindrical tube in which one of the ends 12 is sealed and whose outer diameter substantially corresponds to the outer diameter of the cigarette 1. [ The diameter of the receptacle 80 may vary, for example, from 2 mm to 8 mm. The length can vary from a few millimeters to a few centimeters.

The receptacle 80 contains a sealed container 81 containing a second chemical 8. The flexible filling material 83 surrounding the storage vessel 81 may be positioned within the tube forming the receptacle 80. [ The filling material 83 has a function of allowing the storage container 81 to be positioned at the center of the receptor 80. [

In order to enable the droplets of the second material 8 to be deposited onto the first material 7 (or at least into the outer layer of the first material 7 contained in the capsule 70) , The sealed container 81 is small and preferably in the form of a flexible metering pipette having any suitable shape that can be considered by those skilled in the art. In practice, the reservoir 81 contains from 0.005 ml to 0.05 ml of liquid glycerin. It may be an elongated shape (smaller in diameter than the height) or a thicker shape (larger in diameter than the height).

The storage vessel 81 comprises a peak 82 whose intensity is sufficient to puncture the capsule and through which the second chemical 8 can flow. The peak piece 82 preferably has a shape similar to the shape of the needles of hypodermic syringes. This configuration is particularly suitable for perforating the capsule 70 by pressing along the axis of the cigarette 1 with or without rotational movement to facilitate perforation.

To facilitate perforation, the wall of the capsule 70 advantageously comprises a perforated region 71 (see Figures 6A-6D) intended to be punctured by the peak 82 of the receptacle 80 (Figures 7A-8B) 6h. This perforated region 71 advantageously has the form of a seal which is thinner and / or less resistant than the rest of the walls of the capsule 70. The seal 71 may also be made of a water-tight material in the form of a food-grade plastic or aluminum film. This attachment of the film onto the outer (or internal) wall of the capsule 70 is also provided through a watertight, and proper adhesion.

The receptacle 80 is initially disposed in one of the ends of the cigarette in an arrangement that prevents any contact of the second substance 8 with the first substance 7. Subsequently, the removable receptacle 80 is located at the end 4 to be ignited in an arrangement which allows contact of the second material 8 with the first material 7.

Referring to the embodiment of Figures 5A, 7A and 7B, the receptacle 80 is arranged around the peak piece 82 and is fitted to the end 4 to be ignited in such a way that the peak piece is embedded into the capsule 70. [ (Not shown). This fixed region 11 has the form of a cylindrical portion facing the closed end 12 of the tube forming the receiver 80. The fixed region 11 is open in such a way as to allow it to be fitted onto the end 4 to be ignited. The fixed region 11 has an inner diameter larger than or equal to the outer diameter of the cigarette 1 (for example, 0.1 mm to 1 mm) and a length that can vary from 3 mm to 10 mm. The configuration of the fixed region 11 is such that the receiver 80 is moved onto the suction end opposite the end 4 of the cigarette 1 to be ignited in such a way that the peak piece 82 is embedded into the suction end, Lt; / RTI > Thus, a more rigid connection is obtained between the receiver 80 and the suction end 5. In practice, the receiver 80 is initially fitted on the suction end 5 (Fig. 7A). If the user wishes to ignite the cigarette the user must remove the receptacle 80 from the suction end 5 and remove it from the end 4 to be ignited in such a way that the tip 82 will puncture the capsule 70 (Fig. 7B).

Referring to an alternative embodiment of Figures 5B, 8A and 8B, the receiver 80 is arranged around the peak piece 82 and in a manner that allows the peak piece to be embedded into the capsule 70, 4). ≪ / RTI > The first fixed region 11a is the same as the fixed region 11 defined above. A closing cap may be provided which protects the peak 82 and prevents the storage container 81 from being emptied in response to unintentional pressurization of the walls of the receiver 80 . The receptacle 80 includes a second fixed region 11b opposed to the first fixed region 11a. This second anchoring region 11b is open in such a way as to allow it to be fitted in such a way that the peak piece is separated from the capsule 70 either onto the end 4 to be ignited or onto the suction end 5. [ The second fixed region 11b has an inner diameter larger than or equal to the outer diameter of the cigarette 1 (for example, 0.1 mm to 1 mm) and a length that can vary from 3 mm to 10 mm. In practice, the second fastening region 11b is initially fitted on the end 4 to be ignited or on the suction end 5 (Fig. 8A). If the user wishes to ignite the cigarette the user must first secure the first fixed area 11a on the end 4 to be ignited in such a manner as to detach the receptor 80 and cause the tip piece 82 to puncture the capsule 70 (Fig. 8B).

Referring to an alternative embodiment of Figures 5c, 9a and 9b, the receptacle 80 is absent. The receptacle 80 is no longer fitted to the end 4, but directly punctures the capsule 70. This configuration provides the visibility of the operation of perforating a better capsule 70. Referring to Figure 60, the point of puncturing can be identified with an appropriate marking 73 to provide perforations in the center of the visible portion of the capsule 70. The markings are arranged at the outermost edge of the end 4 to be ignited, for example, when the mark is arranged at the outermost edge of the end portion 4 to be ignited, or when the capsule is covered with a cigarette Has the shape of a cross, point, or target, which is carried out by a pellet 74 (Fig. 6H).

In order to keep the diameter of the cigarette 1 over the entire length so that the receptors 80 are initially arranged on the suction end 5 (Fig. 9a), in particular to prevent tobacco companies from changing the size of the cigarette packet It is advantageous to do. To do this, the receptacle 80 is connected to a cigarette (not shown) by a detachable adhesive tab 13 on the perforations along the dashed lines (e.g. by realizing a traction-rotation movement on the container) 1). The adhesive tabs 13 may be partially coated with an adhesive of a type similar to that found, for example, in POST-IT (R).

The entire receptacle 80 is spherically flexible so that the dispensing of the second material 8 takes place without trouble with the first attempt as a single pressurization of the container. The peak 82 is more rigid, which is not inconsistent with the purpose of the overall flexibility of the receiver 80 and is very easily carried out industrially.

The preferred materials used to implement the receiver 80 and storage vessel 81 are flexible polyethylene due to their good compatibility with their liquids and the flexibility to last sustainably over time. Preferably, however, plasticized paper or carton, aliphatic polymers such as polycaprolactone and polytetramethylene succinate, copolyester, polyester amide or vinyl polymer, natural rubber, etc., such as hydrocarbon it is preferable to use biodegradable and / or biodegradable materials to cope with the influence on the minimum pollution of the environment, such as biopolymers in the form of polysaccharides of elastomers. The flexible material is selected in such a way that the pressure on the wall of the receptacle 80 causes the second chemical 8 to be ejected via the peak 82. If the storage container 81 is of an elongated shape, the user may empty it by pressing (or pinching) the sidewalls. If the storage container is of a thick shape, the user may be emptied by pressing it in the axis of the cigarette.

In an alternative embodiment, the receiver 80 and / or the storage vessel 81 can be made of a rigid material, the displacement of which is such that the second chemical 8 has a peak 82 (In the manner of a syringe) which causes the piston to be discharged through. The selection of the receptors 80 made of a transparent material allows the user to visualize puncturing the fragile zone 71 in the end. Of course, this operation can also be performed blindly by allowing the user to perceive that the capsule 70 is punctured when the end portion 4 of the cigarette 1 is adjacent to the filling material 83.

In another alternative embodiment, not shown, the storage vessel 81 has the shape of a bellows (or accordion) allowing it to be emptied through axial compression. And the filling material 83 are sufficiently flexible to allow this axial pressure in this case.

The peaks 82 can be implemented with a more rigid material such as a soluble material (in this case, its shape is a structure that makes it harder) or a thermosetting polymer or the like that is the same as the storage container 81. In order to simplify the design of the receiver 80, the sealed container 81 and the peak piece 82 advantageously take the form of a single-block part through molding. However, if the material of the storage container 81 is too flexible, it may be considered to use a separate peak 82 made of a harder material. For example, using a peak piece 82 in the form of a harder insert (metal, polyvinyl chloride, etc.) added through bonding or welding onto a storage container 81 or through which a storage container is cast It is possible.

The fill material 83 may be a material similar to that used as a foam or cigarette filters. However, it is desirable to use biodegradable and / or biodegradable materials to address the impact of minimal environmental contamination, such as felt plants.

Referring to Figure 6a, the capsule 70 may have the form of a cylindrical pellet which is fully integrated into the end 4 to be ignited. However, the fitting of the receptacle 80 to the end 4 of the cigarette 1 may cause unacceptable deformations of the cigarette. This results from the fact that the end of the cigarette 1 is not strictly cylindrical.

The closer the diameter of the receiver 80 is to the diameter of the cigarette 1, the more difficult the fitting will be. Therefore, it is important that the cylindrical property of the end portion 4 of the cigarette 1 should be guaranteed. To achieve this, the capsule 70 preferably includes a portion that is configured to serve as a guide to the receiver 80 when the capsule is fitted onto the end 4 to be fired. The capsule 70 can be made to remain in a cylindrical shape with the same function as a shaper of the end portion 4 of the cigarette. 6b), tapered (FIG. 6c), or spherical (FIG. 6d) capsules on the end 4 of the cigarette 1 and the narrowest portion of the capsule 80 In such a way as to provide a good induction for the fitting. 6E, 6F, 6G and 6H, the capsule 70 is a sloped shape whose widest portion is located on the side of the end 4 to be fired. This configuration provides a condition closer to the center of the first material 7 and provides a more uniform ignition of the second material 8 on the entire free surface of the first material, . 6F and 6G, the portion 72 forming the induction is made of a flange whose diameter corresponds to the diameter of the end portion 4, and the flange is covered with the paper 2. [ His height is several millimeters. In Figure 6f, the flange is oriented toward the suction end 5 and in Figure 6g the flange is oriented in the other direction.

Figures 1-4 illustrate how smokers can ignite a cigarette with simple actions, regardless of whether the smoker is holding the cigarette in his hand or whether the cigarette is still attached to the mouth.

The user takes the receptacle 80 (FIG. 1) and positions it against the end to be ignited (FIG. 2) in such a way that the peak piece 82 punctures the capsule 70. The user presses the receiver 80 between the fingers (Figure 3) and causes the second material 8 to contact the first material 7 by causing the second material to flow through the peaks 82 can do. Once the second material 8 contacts the first material 7, the user retrieves the receptacle 80 from the end 4 to ignite (FIG. 4). The reaction is initiated and ignition occurs at the end 4 to be ignited.

The arrangement of the various components and / or means and / or steps of the invention in the above-described embodiments should not be understood as requiring such an arrangement throughout the acts.
