Abstract

Cigarette with filter provided with incisions or tracings following uninterrupted lines which have little resistance to tearing, having firmly closed edges that the smoker will space by deformation of the filter under the mere pressure of the fingers as soon as he has lit the cigarette so as to have the edges in a position of open lips which will allow ambient air to enter the filter.

Description

Cigarette avec filtre et son procédé de fabrication. Cigarette with filter and its manufacturing process.
Il est connu que le seul plaisir du fumeur de cigarettes n'est pas uniquement la fumée mais, en grande partie, les gestes mêmes, d'allumer, de tenir la cigarette et le besoin de tirer sur la cigarette allumée.It is known that the only pleasure of the cigarette smoker is not only the smoke but, in large part, the very gestures, of lighting, of holding the cigarette and the need to pull on the lit cigarette.
L'invention décrite cifaprès et accompagnée d'un dessin a pour objet desfpigarettes permettant au fumeur d'accomplir tous ces gestes sans pour autant aspirer la fumée, donc sans lui faire courir les dangers à sa santé, soit de lui per - mettre d'aspirer un mélange d'air-fumée, donc une fumée très diluée par l'air tel qu'il ressortira de la description ci- apres.The invention described below and accompanied by a drawing has as its object cigarettes allowing the smoker to perform all these gestures without sucking in the smoke, therefore without making him run health hazards, or to allow him to suck a mixture of air-smoke, therefore a smoke very diluted by the air as will emerge from the description below.
Les diverses conceptions plus ou moins compliquées mais inefficaces de filtres déjà connus ont pour but de diminuer la nocivité de la fumée en essayant de modifier la teneur en nicotine et en goudrons. Ainsi, plusieurs catégories de filtres proposés prévoient des canaux logés à l'intérieur de la :nasse filtrante même; d'autres conceptions utilisent, des bandes collées à l'extérieur du manchon qui se rétrécissent à la chaleur de la fumée, ayant pour rôle de diminuer la quantité de la fumée traversant le filtre, sans toutefois l'arrêter ou de diminuer sa concentration.The various more or less complicated but ineffective designs of filters already known are intended to reduce the harmfulness of the smoke by trying to modify the content of nicotine and tars. Thus, several categories of filters proposed provide channels housed inside the filter basket itself; other designs use, strips glued to the outside of the sleeve which shrink with the heat of the smoke, having the role of reducing the amount of smoke passing through the filter, without however stopping it or decreasing its concentration.
On a proposé d'autre part dans la demande de brevet allemande déposée le 29.2.1968 sous numéro P 1657.242.2 un système de filtre caractérisé par une bague coulissante sur le manchon, dans le but de modifier progressivement la coantité aspirée de la fumée sans toutefois d'en arrêter la einétration dans le filtre selon que l'on déplacera ladite bague coulissantelelong du manchon en recouvrant plus ou moins les entrées ouvertes en permanence, dont l' importance invariable a été déterminée une fois pour toutes lors de la fabrication même de la cigarette. Il est cependant connu qu'il est particulieremen^malaisé d'allumer la cigarette lorsque l'air ambiant entre librement à l' intérieur de manchon s'il possède des ouvertures latérales.On the other hand, in the German patent application filed on 29.2.1968 under number P 1657.242.2, there was proposed a filter system characterized by a sliding ring on the sleeve, with the aim of gradually modifying the coantity sucked in smoke without, however, stopping its integration into the filter depending on whether the said sliding ring is moved along the sleeve, more or less covering the permanently open inlets, the invariable importance of which has been determined once and for all during the cigarette manufacturing process. It is known, however, that it is particularly difficult to light the cigarette when the ambient air freely enters the interior of the sleeve if it has side openings.
L'invention consiste principalement en ce que la cigarette munie d'un embout filtrant, possède un manchon dont la paro i est pourvue de très fines incisions allongées 1 (fig.1, ou d'un tracé affaiblissant l'enveloppe du filtre, accusant la forme de lignes ininterrompues, sans permettre pour autant l'entrée de l'air ambiant vers l'intérieur du manchon 4, étant donné qu'autour de ces incisions possédant la forme de lignes ininterrompues, la paroi du manchon continue à faire office de lèvres 2 fermement serrées et ce n'est qu' après que la cigarette aura été allumée que l'on fera éclater lesdites zones 2, les fentes selon l'invention étant suffisamment longues pour les transformer en lèvres ouverte 3 telles que représentées en fig.2, permettant,à partir de cet instant, l'entrée libre à l'air ambiant vers l'intérieur du manchon.Ainsi, la force d'aspiration du fumeur,nécessaire au moment où il allume la cigarette,ne sera pas diminuée, car les zones 2 entourant les fines incisions en forme de lignes ininterrompues appliquées sur la paroi du manchon 4 sont restées fermement serrées et ne seront écartées pour adopter la position de lèvres ouvertes 3 qu'après que la cigarette aura été allumée, ce qui sera provoqué par suite d'une légère déformation de la paroi du manchon soit sous la seule pression des doigts, soit par suite d'un mouvement de torsion exécuté entre le pouce et l'index de la main par exemple, autour.de son axe central ou encore par un tassement dans le sens exial qui raccourcira sa longueur initiale, ce raccourcissement étant obtenu sous la poussée que lejfumeur exercera à la libre extrémité du manchon dans le but de créer de larges ouvertures latérales d'entrée d'air 3 vers la masse filtrante qui vient d'être dénudée autour des incisions 1, allongées, jusqu'alors fermées.The invention consists mainly in that the cigarette provided with a filtering tip, has a sleeve whose side i is provided with very fine elongated incisions 1 (fig.1, or a path weakening the envelope of the filter, showing the shape of unbroken lines, without allowing the entry of ambient air into the interior of the sleeve 4, since around these incisions having the shape of unbroken lines, the wall of the sleeve continues to act as lips 2 firmly tightened and it is only after the cigarette has been lit that these zones 2 will be burst, the slots according to the invention being long enough to transform them into open lips 3 as shown in FIG. 2, allowing, from this moment, the free entry to the ambient air towards the inside of the sleeve. Thus, the suction power of the smoker, necessary at the time when he lights the cigarette, will not be reduced, because zones 2 surrounding the s fine incisions in the form of uninterrupted lines applied to the wall of the sleeve 4 have remained firmly tightened and will not be discarded to adopt the position of open lips 3 until after the cigarette has been lit, which will be caused as a result of a slight deformation of the wall of the sleeve either under the sole pressure of the fingers, or as a result of a twisting movement carried out between the thumb and the index finger of the hand for example, around its central axis or by a compaction in the exial direction which will shorten its initial length, this shortening being obtained under the thrust that the smoker will exert at the free end of the sleeve in order to create wide lateral air intake openings 3 towards the mass filter which has just been stripped around the incisions 1, elongated, hitherto closed.
En appliquant au manchon un léger mouvement de torsion autour de son axe central, les lèvres adopteront une υosition vrillée, leurs bords s'éloignant ainsi les uns des autres, créant des ouvertures d'aspiration 3 permettant donc l'entrée de l'air ambiant. A partiride ce moment et non avant, les aspirations du fumeur seront entièrement comblées par leyolume d'air pénétrant par les fentes maintenant déjà ouvertes et par conséquant la force d'aspiration du fumeur est annulée en direction de la partie remplie de tabac 5, devenant ainsi trop faible pour attiser le feu de la cigarette allumée ni pour drainer sa fumée vers la masse filtrante que la fumée ne pourra donc plus traverser, laissant la cigarette se consumer toute seule, les aspirations du fumeur ne l'atteignant pas.By applying a slight twisting movement to the sleeve around its central axis, the lips will adopt a twisted position, their edges thus moving away from each other, creating suction openings 3 thus allowing the entry of ambient air. . From this moment and not before, the aspirations of the smoker will be fully satisfied by the air volume penetrating through the slots now already open and consequently the suction force of the smoker is canceled in the direction of the part filled with tobacco 5, becoming thus too weak to stoke the fire of the lit cigarette nor to drain its smoke towards the filtering mass that the smoke will therefore no longer be able to pass through, leaving the cigarette to burn on its own, the aspirations of the smoker not reaching it.
Dans le cas où les bords des ouvertures ne seront écartés eue faiblement, le fumeur pourra encore aspirer de la fumée mais, elle sera mélangée avec de l'air ambiant entré par les lèvres bienque très légèrement écartées.In the case where the edges of the openings are not spread slightly, the smoker can still suck in smoke but, it will be mixed with ambient air entered by the lips although very slightly spread.
Selon une réalisation préférentielle de l'invention, la profondeur des entailles 1, en lignes ininterrompues sera tellement réduite par suite d'une limitation de la pénétration de l'outil traceur que les fines incisions précedemment décrites seront réduites à des traces superficielles dont on aura marqué la face extérieure du manchon qui y est ainsi affaibli, ces traces constituant des lignes de moindre résistance à la déchirure que l'on provoquera seulement après avoir allumé la cigarette grâce à une délormation du manchon, ces déchirures ainsi créées formant des lors des lèvres ouvertes à l'air ambiant vers l'intérieur du manchon. L'opération du traçage des lignes de moindre résistance sera réalisée selon la technique bien connue dans l'industrie du papier et des cartonnages a l'aide de traceurs non illustrés qui pourront avoir la forme de laites, de collettes ou de cylindres gravés. Ainsi la force de l'aspiration du fumeur qui est nécessaire au moment où l'on allume la cigarette,ne sera pas diminuée, les lèvres 2 telles que représentées en fig.l encadrant les fines incisions ininterrompues appliquées sur la paroi dumanchon,resteront étroitement serrées et ne seront écartées pour adopter la position de larges ouvertures 3 (fig.2) qu'après que la cigarette aura été allumée, étant écartées aisni par suite de la déformation du manchon, exécutée comme il est décrit plus haut, la masse filtrante venant à être dénudée à la suite de la déformation des lèvres 2. Les incisions ininterrompues pourront suivre la forme de lignes courbes, de lignes ondulées, en zig-zag ou bine rectilignes,parall-les ou inclinées à l'axe central du manchon. Avant de réaliser la déformation du manchon devant provoquer les déchirures,la continuité de la paroi de manchon ne sera pas encore interrompue, car le tracé des empreintes affaiblissant la paroi,présente seulement une amorce à la déchirure qui sera ultérieurement provoquée. Ces lignes de moindre résistance pourront être tracées par des empreintes poursuivant des lignes continues qui amincissent et affaiblissent donc ia paroi dumanchon pour y donner ultérieurement naissance à de longues fentes d'aspiration qu'on aura formées à la suite de déforma tion ultérieure, appliquée au manchon après avoir allumé la cigarette. Suivant une autre alternative de réalisation, les incisions 7 représentées en fig.3 pourront être appliquées perpendiculairement au sens de la longueur du filtre 4.Elles pourront être rangées parallèlement sur les deux côtés opposés du filtre, en quinconce. Cette réalisation permet au fumeur d' écarter les entailles 7 à son gré, en allongeant la longueur initiale du manchon 4 à la menière d'un accordéon ou bien de la resserrer par un mouvement de tassement de la longueur du manchon, pouvant ainsi régler le volume d'air extérieur admis vers l'intérieur du manchon.Le fumeur est ainsi en mesure de renforcer ou de diminuer;après avoir allumé la cigarette,la force de son aspirâtion,pouvant ainsi doser lui-même le volume de la fumée, soit d'en arrêter totalement la passage s' il en éprouve le besoin ou de doser la concentration du mélange air-fumée. La cigarette conçue selon l'invention permet cependant aussi longtemps que l'on n'aura pas créé des ouvertures élargies, ayant volontairement évité à déformer le manchon, d'aspirer la fumée pure et de'lavaler, comme avec toute autre cigarette normale. Toutefois, le fumeur pourra arrêter de recevoir la fumée dès qu'il aur, à son désir, et ce à tout moment, décidé de créer les ouvertures d'entrée d'air, en déformant le manchon comme décrit plus haut.According to a preferred embodiment of the invention, the depth of the notches 1, in unbroken lines will be so reduced as a result of a limitation of the penetration of the tracer tool that the fine incisions previously described will be reduced to superficial traces which will have marked the outer face of the sleeve which is thus weakened there, these traces constituting lines of least resistance to tearing which will be caused only after lighting the cigarette thanks to a delormation of the sleeve, these tears thus created forming at the lips open to ambient air towards the inside of the sleeve. The operation of tracing the lines of least resistance will be carried out according to the technique well known in the paper and cardboard industry using tracers not illustrated which may have the form of milks, collets or engraved cylinders. Thus the strength of the suction of the smoker which is necessary at the time when the cigarette is lit, will not be reduced, the lips 2 as shown in fig.l framing the fine uninterrupted incisions applied to the wall of the chest, will remain tightly tight and will not be spread to adopt the position of large openings 3 (fig.2) only after the cigarette has been lit, being spread aisni as a result of the deformation of the sleeve, executed as described above, the filter mass coming to be stripped as a result of the deformation of the lips 2. The uninterrupted incisions may follow the form of curved lines, wavy lines, in a zig-zag or straight line, parallel or inclined to the central axis of the sleeve. Before carrying out the deformation of the sleeve intended to cause the tears, the continuity of the sleeve wall will not be interrupted yet, since the tracing of the imprints weakening the wall, presents only a primer to the tear which will be subsequently caused. These lines of least resistance can be traced by imprints following continuous lines which thinner and therefore weaken the wall of the link to give rise thereafter to long suction slits which will have been formed as a result of subsequent deformation, applied to the sleeve after lighting the cigarette. According to another alternative embodiment, the incisions 7 shown in fig.3 can be applied perpendicular to the length direction of the filter 4. They can be stored in parallel on the two opposite sides of the filter, staggered. This embodiment allows the smoker to spread the notches 7 at will, by extending the initial length of the sleeve 4 to the hinge of an accordion or else tightening it by a compacting movement of the length of the sleeve, thus being able to adjust the volume of outside air admitted towards the inside of the sleeve. The smoker is thus able to reinforce or decrease; after lighting the cigarette, the strength of its suction, thus being able to adjust itself the volume of the smoke, i.e. to completely stop the passage if he feels the need or to dose the concentration of the air-smoke mixture. The cigarette designed according to the invention allows however as long as one has not created widened openings, having deliberately avoided deforming the sleeve, to suck in the pure smoke and to wash down, as with any other normal cigarette. However, the smoker can stop receiving the smoke as soon as he has, at his desire, and at any time, decided to create the air intake openings, by deforming the sleeve as described above.
On peut donc facilement allumer la cigarette, objet de 1( invention, le tirage nécessaire à cela n'étant en rien altéré puisque l'air ambiant ne peut pas encore pénétrer latéralement vers l'intérieur du manchon filtrant. Ce n'est donc que losque la cigarette est déjà allumée normalement sans difficulté que le fumeur y créera les ouvertures d'entrée d'air, soit pour arrêter ainsi l'arrivée de la fumée, soit pour établir un mélange d'air avec la fumée.It is therefore easy to light the cigarette, object of 1 (invention, the draft necessary for this being in no way altered since the ambient air cannot yet penetrate laterally towards the inside of the filter sleeve. It is therefore only when the cigarette is already lit normally without difficulty that the smoker will create the air intake openings, either to stop the arrival of smoke, or to establish a mixture of air with the smoke.
Par contre, les cigarettes connues jusqu'à présent,proposées selon la demande de brevet allemande du 29.2.1968 numéro P 1657.242.2 citée plus haut, ne pouvaient être al - lumées que bien difficilement, les perforations latérales du manchon y étant définitivement ouvertes déjà depuis leur fabrication donc, contrairement, à la présente invention, la quantité de la fumée pouvait y être augmentée par le déplacement d'une bague coulissante, caractérisant ladite demande allemande,mai^ήullement arrêtée. Sans sortir du cadre de l'invention, le manchon pourra également être formé d'une bande tissée ou tressée à partir de fils naturels ou synthétiques dont les mailles auront la serrage judicieusement choisi,ladite bande tissée ou tressée possédant grâce à un encollage suffisant,la rigidité nécessaire pour protéger la masse filtrante qui en est enrobée.

Without departing from the scope of the invention, the sleeve may also be formed from a woven or braided strip from natural or synthetic threads, the meshes of which will have the judiciously chosen tightening, said woven or braided strip having, thanks to sufficient sizing, the rigidity necessary to protect the filter mass which is coated with it.
