Description

Améliorations à un article pour fumeur.Improvements to a smoking article.
La présente invention constitue une amélioration de l'article pour fumeurs divulgué dans la demande de brevet PCT/BE96/00057 (WO 96/41546) .The present invention constitutes an improvement to the article for smokers disclosed in patent application PCT / BE96 / 00057 (WO 96/41546).
L'article pour fumeurs selon la demande susmentionnée consiste en un dispositif destiné à diminuer l'émission de fumée par le bout brûlant de la cigarette (fumée de "courant latéral", "side stream smo e"). Le dispositif consiste en une pièce allongée comportant un orifice circulaire longitudinal qui permet au dispositif de coulisser avec frottement le long d'une cigarette sous l'effet des doigts de l'utilisateur.The article for smokers according to the above-mentioned application consists of a device intended to reduce the emission of smoke from the burning end of the cigarette ("side stream smo e" smoke). The device consists of an elongated part comprising a longitudinal circular orifice which allows the device to slide with friction along a cigarette under the effect of the user's fingers.
Le dispositif comprend une partie proximale réalisée en matériau dimensionnellement stable et une partie distale destinée à recevoir le bout brûlant de la cigarette entre deux aspirations de fumées, ce bout se présentant de préférence sous la forme d'une bague cylindrique réalisée en un matériau utilisé pour la fabrication de fourneau de pipe. De préférence la partie distale et la partie proximale sont séparables.The device comprises a proximal part made of dimensionally stable material and a distal part intended to receive the burning end of the cigarette between two aspirations of smoke, this end preferably being in the form of a cylindrical ring made of a material used for the manufacture of pipe furnaces. Preferably the distal part and the proximal part are separable.
Un matériau particulièrement préféré pour la partie distale est le bois de bruyère tel qu'utilisé traditionnellement pour la fabrication de pipes. Un processus de séchage du bois de bruyère, préalablement à sa découpe peut s'avérer particulièrement indiqué pour favoriser la reproductibilité des découpes. La stabilité dimensionnelle de la bruyère semble en effet sensiblement dépendre de l'humidité ambiante.A particularly preferred material for the distal part is briar wood as traditionally used for the manufacture of pipes. A process of drying briar wood, before cutting it, may be particularly suitable for promoting the reproducibility of the cuts. The dimensional stability of the heather indeed seems to depend significantly on the ambient humidity.
On a maintenant observé que le matériau préféré pour la partie proximale est un plastique résistant à la chaleur, plus particulièrement une résine de polyetherimide ULTEM (marque déposée, General Electric), modifiée ou non. Cette résine est moulable, est dimensionnellement stable, et peut résister à une température prolongée de 170° C sans être significativement altérée. Les produits de combustion éventuelle de ce matériau ne sont guère plus toxiques que ceux résultant de la combustion d'un bois (CO, C02 , H20) . En utilisation normale, la matière plastique de l'élément proximal ne dépasse pas une température de 70-100°C.It has now been observed that the preferred material for the proximal part is a heat-resistant plastic, more particularly a polyetherimide resin ULTEM (registered trademark, General Electric), modified or not. This resin is moldable, is dimensionally stable, and can withstand an extended temperature of 170 ° C without being significantly altered. The products of possible combustion of this material are hardly more toxic than those resulting from the combustion of a wood (CO, C02, H 2 0). In normal use, the plastic of the proximal element does not exceed a temperature of 70-100 ° C.
On a constaté que la bague et la partie proximale du dispositif ci-dessus, lors de l'utilisation de l'article, se désolidarisent facilement s'ils ne sont retenus que par l'effet de friction . En particulier, et de manière surprenante, la bague de bruyère aurait une tendance à rétrécir sous l'effet de la chaleur et en conséquence de se désolidariser de la partie proximale lorsque les deux parties sont maintenues par friction. Ce problème est général pour des articles constitués de deux matériaux différents et destinés à coulisser sur une cigarette à bout brûlant. L'utilisation de colle s'avère désavantageuse car la colle chauffée est apte à altérer désagréablement le goût de la fumée. La présence de colle entraîne également un désavantage économique lors du montage du dispositif. Il est également avantageux, grâce à un montage réversible que l'usage de colle ne permet pas, de pouvoir dissocier les composants de l'article, par exemple pour remplacer un seul de ces composants.It was found that the ring and the proximal part of the above device, when using the article, are easily detached if they are only retained by the friction effect. In particular, and surprisingly, the heather ring would have a tendency to shrink under the effect of heat and consequently to dissociate from the proximal part when the two parts are held by friction. This problem is general for articles made of two different materials and intended to slide on a cigarette with a hot end. The use of glue is disadvantageous because the heated glue is capable of unpleasantly altering the taste of the smoke. The presence of glue also leads to an economic disadvantage when mounting the device. It is also advantageous, thanks to a reversible mounting that the use of glue does not allow, to be able to dissociate the components of the article, for example to replace only one of these components.
Ce problème a été avantageusement résolu selon la présente invention en prévoyant au moins une fente longitudinale, de préférence 3 à 4 fentes, dans la section de la paroi de la partie proximale qui reçoit la bague distale. Lors du montage du dispositif, la bague peut alors être insérée à force en profitant de la flexibilité relative du matériau (avantageusement un plastique comme susmentionné) de la partie proximale. Il s'ensuit un effet plus efficace de serrage et/ou d' encliquetage de la bague en bruyère. La rétention de la bague, le montage et le démontage de l'article s'en trouve facilité.This problem has been advantageously solved according to the present invention by providing at least one longitudinal slot, preferably 3 to 4 slots, in the section of the wall of the proximal part which receives the distal ring. When mounting the device, the ring can then be inserted by force taking advantage of the relative flexibility of the material (advantageously a plastic as mentioned above) of the proximal part. This results in a more effective tightening and / or snap-fastening effect on the briar ring. The retention of the ring, the assembly and disassembly of the article is thereby facilitated.
La fente longitudinale, qui est de préférence une fente traversante, s'étend de l'extrémité libre de la partie proximale sur une longueur substantielle de la section destinée à recevoir au moins partiellement la bague. La largeur de la fente varie par exemple de 0 , 5 à 2 mm et sa longueur de 1 à 4 mm. Avantageusement, la bague en bruyère est légèrement conique. Dans ce cas la partie la plus large de la bague est insérée en premier lieu, procédé apte à créer ainsi un effet d' encliquetage .The longitudinal slot, which is preferably a through slot, extends from the free end of the proximal part over a substantial length of the section intended to at least partially receive the ring. The width of the slot varies for example from 0.5 to 2 mm and its length from 1 to 4 mm. Advantageously, the briar ring is slightly conical. In this case, the widest part of the ring is inserted first, a process able to create a snap effect.
L'obtention économique de bagues en bruyère de petites dimensions présente des problèmes lorsqu'on les fabrique en faisant appel à un travail classique du bois, p.e. par tournage. Il en est ainsi en particulier pour l'obtention de l'ouverture circulaire.Obtaining small size briar rings economically presents problems when they are produced using conventional woodwork, eg by turning. This is particularly so for obtaining the circular opening.
Selon un aspect de la présente invention, des plaquettes de bruyère d'une épaisseur correspondant à la longueur de la bague à obtenir, sont découpées par un faisceau laser en utilisant une technique de découpe de laser classique, par exemple telle que celle utilisée pour découper des panneaux de bois MSD.According to one aspect of the present invention, briar platelets of a thickness corresponding to the length of the ring to be obtained, are cut by a laser beam using a conventional laser cutting technique, for example such as that used for cutting MSD wood panels.
Le laser découpe une circonférence intérieure puis une circonférence extérieure, la différence des diamètres correspondant à l'épaisseur de la bague. La découpe, en particulier du bord extérieur de la bague, peut être très légèrement conique (quelques degrés) .The laser cuts an inner circumference then an outer circumference, the difference in diameters corresponding to the thickness of the ring. The cut, in particular from the outer edge of the ring, can be very slightly conical (a few degrees).
Cette manière de procéder présente l'avantage supplémentaire de brûler la surface interne de la bague qui sera soumise à la chaleur du bout brûlant de la cigarette, en "rodant" en quelque sorte cette surface préalablement à la première utilisation par le fumeur. La surface externe par contre, peut être travaillée, par exemple par des procédés classiques de tournage permettant ainsi l'obtention de surface de décoration et ou d'ailettes, pas de vis ou mêmes des trous plus ou moins profonds présents dans le but, entre autres, de dissiper la chaleur.This procedure has the additional advantage of burning the internal surface of the ring which will be subjected to the heat of the burning end of the cigarette, "sorting" this surface in a way before the first use by the smoker. The external surface, on the other hand, can be worked, for example by conventional turning processes thus making it possible to obtain decorative surface and or fins, no screws or even more or less deep holes present for the purpose, inter alia, of dissipating heat.
La technique de découpe laser est favorable car elle permet de manière inhérente d'obtenir des bagues légèrement coniques (quelques degrés) . L'extrémité du canon du laser décrit un cercle en restant fixe à une certaine distance de la plaquette dans laquelle la bague est découpée .The laser cutting technique is favorable because it inherently makes it possible to obtain slightly conical rings (a few degrees). The end of the barrel of the laser describes a circle while remaining fixed at a certain distance from the plate in which the ring is cut.
Avantageusement du point de vue économique, les plaquettes de bois de bruyère proviennent en fait de résidus de fabrication, essentiellement de fabrication de pipes, de telle sorte que la matière de départ est très bon marché .Advantageously from the economic point of view, the briar wood chips actually come from manufacturing residues, essentially from the manufacture of pipes, so that the starting material is very inexpensive.
La fabrication en série en est grandement facilitée.Mass production is greatly facilitated.
En effet, selon un aspect de l'invention, les plaquettes de bois de bruyère sont disposées sur un support à surface quadrillée, chaque carré ou rectangle étant physiquement délimité et pouvant recevoir dans un de ces coins une plaquette comportant au moins deux bords orthogonaux. L'automatisation et le repérage de la coupe par faisceau laser en est ainsi grandement facilité. On prévoit des moyens de maintien ou de calage des plaquettes dans un coin de chaque casier, par exemple les coins supérieurs gauche des casiers formés. Il est bien entendu que l'utilisation d'une coupe au laser pour obtenir des bagues de bruyère, peut être appliquée pour d'obtention d'autres articles que l'article pour fumeur susmentionné.In fact, according to one aspect of the invention, the briar wood boards are arranged on a support with a grid surface, each square or rectangle being physically delimited and capable of receiving in one of these corners a board comprising at least two orthogonal edges. Automation and location of the cut by laser beam is thus greatly facilitated. Means are provided for holding or wedging the plates in a corner of each locker, for example the upper left corners of the formed lockers. It is understood that the use of a laser cut to obtain heather rings can be applied to obtain articles other than the aforementioned smoking article.
Selon un autre aspect de l'invention, la partie proximale est essentiellement ajourée, laissant ainsi un accès libre à l'air de la plus grande partie du corps de la cigarette située sous cette partie. Outre l'allégement souhaitable, cette caractéristique est importante pour éviter la condensation de la fumée de cigarette, le dépôt de goudron et le goût désagréable qui en résulte.According to another aspect of the invention, the proximal part is essentially perforated, thus leaving free access to the air of the largest part of the body of the cigarette situated under this part. In addition to the desirable lightening, this characteristic is important to avoid condensation of cigarette smoke, tar deposition and the unpleasant taste which results therefrom.
Selon une variante de l'invention, la partie proximale est plus courte que la partie distale, cette dernière comprenant alors les ajourements et étant faite d'une pièce en matériau susceptible de servir pour la fabrication de pipe. La partie proximale peut se réduire à un anneau, avec éventuellement des guides longitudinaux (p.e. sous forme de tiges) s ' étendant de sa face interne parallèles à son axe et qui est apte à se glisser sous la partie distale. Ces guides (arêtes longitudinales de frottement) sont destinés à entrer en contact direct avec la cigarette et à maintenir celle-ci. L'extrémité de la partie proximale, et éventuellement l'anneau, peuvent être biseautées pour faciliter l'insertion de la cigarette. La bague proximale peut alors être constitué d'un matériau noble ou même précieux. Selon le mode de réalisation actuellement préféré, la partie proximale est cependant plus longue et comprend les ajourements destinés à aérer la corps de la cigarette. Cette caractéristique peut se présenter pour les articles définis dans la revendication 1 de la demande de brevet PCT susmentionnée.According to a variant of the invention, the proximal part is shorter than the distal part, the latter then comprising the openings and being made of a piece of material capable of being used for the manufacture of pipe. The proximal part can be reduced to a ring, possibly with longitudinal guides (eg in the form of rods) extending from its internal face parallel to its axis and which is able to slide under the distal part. These guides (longitudinal friction edges) are intended to come into direct contact with the cigarette and to maintain it. The end of the proximal part, and possibly the ring, can be bevelled to facilitate the insertion of the cigarette. The proximal ring can then be made of a noble or even precious material. According to the currently preferred embodiment, the proximal part is however longer and comprises the openings intended to ventilate the body of the cigarette. This characteristic may be present for the articles defined in claim 1 of the aforementioned PCT patent application.
Selon un autre aspect de l'invention, la surface interne de la partie proximale comprend généralement en effet des arêtes longitudinales de frottement. Seules les sommets de ces arêtes sont en contact avec la cigarette et glissent sur celle-ci en compressant le papier et pénétrant légèrement dans le corps de la cigarette . La friction est suffisante pour maintenir cette partie proximale le long de la cigarette, avec ou sans la bague distale, contre l'effet de la gravité ou d'inertie.According to another aspect of the invention, the internal surface of the proximal part generally in fact comprises longitudinal friction edges. Only the tops of these edges are in contact with the cigarette and slide thereon compressing the paper and slightly penetrating into the body of the cigarette. The friction is sufficient to maintain this proximal part along the cigarette, with or without the distal ring, against the effect of gravity or inertia.
Pour l'utilisation du dispositif de l'invention, 1 ' extrémité à fumer de la cigarette est insérée dans la partie proximale du dispositif afin de coulisser vers la bague avant de la traverser et d'émerger du côté distal avant d'être allumée. L'insertion dans l'orifice peut être facilitée par la présence d'un chanfrein.For the use of the device of the invention, the smoking end of the cigarette is inserted into the proximal part of the device in order to slide towards the ring before crossing it and emerging from the distal side before being lit. Insertion into the hole can be facilitated by the presence of a chamfer.
L'invention propose donc notamment un article pour fumeur apte à coulisser sur une cigarette et destiné à atténuer 1 ' émission de fumée de courant latéral provenant de ladite cigarette, caractérisé en ce qu'il est constitué d'une partie proximale et d'une partie distale la partie proximale étant constituée d'un corps cylindrique en matière synthétique et comportant des ouvertures de telle sorte que plus de 30% , de préférence plus de 50%, de la surface extérieure de la cigarette contenue sous cette partie proximale n'est pas recouverte par un élément de cette partie proximale, la partie proximale comportant en outre, sur sa surface intérieure des arêtes de friction essentiellement longitudinales, une extrémité du corps cylindrique formant une cavité destinée à recevoir une partie distale, l'autre extrémité du corps cylindrique comportant un bourrelet apte à faciliter la prise par un ou plusieurs doigts de 1 ' utilisateur. la partie distale est constituée d'une bague en bruyère, de préférence découpée par laser, essentiellement cylindrique ou légèrement coniques, coaxiale à la partie proximale, et maintenue à une extrémité de celle-ci, le diamètre intérieur de la bague étant approximativement égal ou très légèrement supérieur au diamètre extérieur de la cigaretteThe invention therefore proposes in particular an article for a smoker capable of sliding on a cigarette and intended to attenuate the emission of side current smoke from said cigarette, characterized in that it consists of a proximal part and a distal part the proximal part consisting of a cylindrical body of synthetic material and having openings so that more than 30%, preferably more than 50%, of the external surface of the cigarette contained under this proximal part is not covered by an element of this proximal part, the proximal part further comprising, on its internal surface essentially longitudinal friction edges, one end of the cylindrical body forming a cavity intended to receive a distal part, the other end of the cylindrical body comprising a bead adapted to facilitate the grip by one or more fingers of one user. the distal part consists of a briar ring, preferably cut by laser, essentially cylindrical or slightly conical, coaxial with the proximal part, and held at one end of the latter, the internal diameter of the ring being approximately equal or very slightly greater than the outside diameter of the cigarette
- la partie distale présentant de préférence des fentes aptes à assurer une meilleure solidarisation de la partie distale et proximale, tout en permettant la séparation à force de ces composants.- The distal part preferably having slots capable of ensuring better securing of the distal and proximal part, while allowing the force separation of these components.
L'invention sera mieux comprise à l'examen des dessins et à la lecture de l'exemple de réalisation non limitatif qui suivent . Des plaquettes de bruyère carrée de 45 x 45 mm et de 7,5 mm d'épaisseur provenant de résidus de la fabrication de pipes, sont séchées à 60°C pendant 3 à 4 jours. Les plaquettes sont placées sur une platine comportant une surface quadrillée, délimitant des supports carrés juxtaposés formant casiers, chaque plaquette étant calée par un ergot au coin supérieur gauche du support, les coins étant en contact . Un faisceau laser au C02 connu en soi, réglé et positionné sur base des coordonnées des supports à casiers, découpe dans chaque plaquette 9 bagues dont le diamètre extérieur est de 12,55 mm et le diamètre intérieur 7,75 mm. Etant donné la technique particulière du mouvement de la tête d'émission laser, la découpe fournit des bagues légèrement coniques .The invention will be better understood on examining the drawings and on reading the following nonlimiting exemplary embodiment. 45 x 45 mm and 7.5 mm thick square briar wafers from residues from pipe making are dried at 60 ° C for 3 to 4 days. The plates are placed on a plate comprising a gridded surface, delimiting juxtaposed square supports forming compartments, each plate being wedged by a lug at the upper left corner of the support, the corners being in contact. A C02 laser beam known per se, adjusted and positioned on the basis of the coordinates of the rack supports, cut from each wafer 9 rings whose outside diameter is 12.55 mm and inside diameter 7.75 mm. Given the particular technique of movement of the laser emission head, the cutout provides slightly conical rings.
Le laser peut être ainsi un laser au C02 (type VFA 1200, 1.7 à 2.2 kW, LASERCO B, dispositif Wegman-Basel) avec une tête à découper haute pression et une platine mobile de 3000 x 500 mm guidé par un système HP900.The laser can thus be a C02 laser (type VFA 1200, 1.7 to 2.2 kW, LASERCO B, Wegman-Basel device) with a high pressure cutting head and a 3000 x 500 mm moving stage guided by an HP900 system.
En se référant aux Figs la à le, on illustre l'article qui a fait l'objet d'une amélioration selon l'invention. On distingue l'article formé d'un manchon 2 (élément proximal) et d'une bague 1 associée à l'extrémité distale du manchon. Une cigarette 10 peut être insérée par coulissement dans l'article.Referring to Figs la to, illustrates the article which has been improved according to the invention. We distinguish the article formed by a sleeve 2 (proximal element) and a ring 1 associated with the distal end of the sleeve. A cigarette 10 can be slidably inserted into the article.
En se référant à la Fig. 2, une bague 1 obtenue selon le procédé susmentionné est insérée et fixée par friction dans une extrémité en manchon 7 de l'élément proximal 2 de forme essentiellement cylindrique. La légère conicité des bagues permet un coincement aisé et stable de la bague dans la cavité de réception cylindrique 8 de l'élément en plastique. En absorbant de l'humidité ambiante, le diamètre de la bague augmente et produira un coincement stable des deux éléments.Referring to FIG. 2, a ring 1 obtained according to the aforementioned method is inserted and fixed by friction in a sleeve end 7 of the proximal element 2 of essentially cylindrical shape. The slight taper rings allows easy and stable wedging of the ring in the cylindrical receiving cavity 8 of the plastic element. By absorbing ambient humidity, the diameter of the ring increases and will produce a stable wedging of the two elements.
L'élément proximal 2 en plastique ULTEM 1000 (General Electric) a été obtenu par moulage. L'élément de bague proximale 2 mesure 25 mm et est largement ajourée par la présence d'orifices, le corps cylindrique principal se présentant sous la forme d'un treillis avec 4 rangées de 4 orifices rectangulaires 3. L'ensemble pèse approximativement 1 g.The proximal element 2 made of ULTEM 1000 plastic (General Electric) was obtained by molding. The proximal ring element 2 measures 25 mm and is largely perforated by the presence of orifices, the main cylindrical body being in the form of a trellis with 4 rows of 4 rectangular orifices 3. The whole weighs approximately 1 g .
La surface intérieure de la partie cylindrique ajourée comprend quatre arêtes longitudinales 4 destinées à glisser le long de la cigarette sous l'effet de la pression longitudinale exercée par un ou deux doigts de l'utilisateur. Ces arêtes longitudinales 4 ne s'étendent de préférence pas jusqu'à l'extrémité cylindrique pleine formant manchon de réception de la bague en bruyère. A ce niveau, un certain espace annulaire libre 6 est ainsi laissé autour de la cigarette.The inner surface of the perforated cylindrical part comprises four longitudinal edges 4 intended to slide along the cigarette under the effect of the longitudinal pressure exerted by one or two fingers of the user. These longitudinal edges 4 preferably do not extend to the solid cylindrical end forming a sleeve for receiving the briar ring. At this level, a certain free annular space 6 is thus left around the cigarette.
A l'autre extrémité, un bourrelet cylindrique 5 est prévu afin de faciliter la manipulation de l'ensemble par un ou plusieurs doigts de l'utilisateur.At the other end, a cylindrical bead 5 is provided to facilitate handling of the assembly by one or more fingers of the user.
Au moins une fente longitudinale (9) , de préférence 3 à 4 fentes, sont prévues dans la section de la paroi de la partie proximale qui reçoit la bague distale. La bague peut alors être insérée à force en profitant de la flexibilité relative du plastique de la partie proximale . Il s'ensuit un effet plus efficace de serrage et/ou d' encliquetage de la bague en bruyère.At least one longitudinal slot (9), preferably 3 to 4 slots, are provided in the section of the wall of the proximal part which receives the distal ring. The ring can then be inserted by force taking advantage of the relative flexibility of the plastic of the proximal part. This results in a more effective tightening and / or snap-fastening effect on the briar ring.
Avantageusement également, la partie réceptrice en plastique peut présenter une certaine conicité , prévue p.e. de moulage, pour remplacer la conicité de la bague distale ou, plus avantageusement encore, accentuer cet effet d ' encliquetage et la fixation efficace de la bague, même à chaud, lorsque les deux éléments présentent une conicité complémentaire.Advantageously also, the plastic receiving part can have a certain taper, provided for molding, to replace the taper of the distal ring or, more advantageously still, accentuate this snap-fastening effect and the effective fixing of the ring, even when hot , when the two elements have a complementary taper.
L'homme de l'art comprendra par ailleurs que la partie distale peut soit s'adapter dans une extrémité du manchon cylindrique proximal ou, avec un effet sensiblement équivalent, s'adapter et se fixer partiellement autour d'une section du manchon cylindrique, les surfaces internes du manchon (partie proximale) et de la bague (partie distale) affleurant. Les améliorations susmentionnées peuvent évidemment s'adapter à ce dernier cas .Those skilled in the art will also understand that the distal part can either be adapted in one end of the proximal cylindrical sleeve or, with a substantially equivalent effect, be adapted and partially fixed around a section of the cylindrical sleeve, the internal surfaces of the sleeve (proximal part) and of the ring (distal part) flush. The improvements mentioned above can obviously be adapted to the latter case.
On comprendra également que les différents aspects décrits dans le présent exposé, y compris dans l'exemple de réalisation, peuvent être généralisés et peuvent être considérés séparément ou en combinaisons quelconques si celles-ci sont compatibles. It will also be understood that the various aspects described in the present description, including in the embodiment, can be generalized and can be considered separately or in any combinations if these are compatible.
