Description

Article Pour fumeurs La prdsente invention a pour objet un article pour fumeurs tel que, par exemple, un fume- cigarette, un fume-eigare, ou une pipe, compre- nant un conduit pour la fumee du tabac dans lequel est introduit un filtre. 0n connait dejä des fume-cigare, fume-cigarette et pipes comportant des filtres amovibles pour eliminer les goudrons, les rdsines, la nicotine et autres 616ments irritants du tabac. Article For Smokers The subject of the present invention is an article for smokers such as, for example, a cigarette holder, a cigarette holder, or a pipe, comprising a duct for tobacco smoke into which a filter is inserted. We already know of cigar holders, cigarette holders and pipes comprising removable filters to eliminate tars, resins, nicotine and other irritants from tobacco.

Jusqu'ä pr6sent, 1e conduit pour la fumee de tels articles pour fumeurs comportant un filtre 6tait approximativement cylindrique, 1e filtre 6tant lui-meme approximativement cylindrique. Pour faciliter 1'enlevement du filtre et son remplacement, an lui donnait une seetion droite 16g6rement plus faible que celle du conduit prevu pour la fum6e. De ce fait, an constatait qu'une certaine quantit6 de fumee pouvait passet 1e long du filtre dans la petite zone s6parant ce dernier de la paroi du conduit, de teile maniere que cette fumee pouvait arriver saus etre filtr6e jusqu'au fumeur. Hitherto, the smoke duct of such smokers' articles incorporating a filter has been approximately cylindrical, the filter itself being approximately cylindrical. To facilitate the removal of the filter and its replacement, it was given a straight section slightly weaker than that of the pipe provided for the smoke. As a result, it was found that a certain amount of smoke could pass along the filter in the small area separating it from the wall of the flue, so that this smoke could arrive without being filtered to the smoker.

L'invention a pour but d'empecher la fum6e de passet 1e long du filtre saus traverser celui-ei. A cet effet, 1'article pour fumeurs selon Pin- vention, comprenant un conduit pour la fum6e du tabac dans lequel est introduit un filtre, est caracterisd par 1e fait qu'au moins un trongon longitudinal de la paroi dudit conduit est en contact avec au moins un trongon longitudinal de la paroi peripherique dudit filtre dispos6 dans ledit conduit, de maniere ä formet un joint hermetique pour tous fluides entre ces deux trongons de paroi et ä obliger ainsi tonte la fum6e ä traverser 1e filtre avant d'atteindre la sortie dudit conduit. The object of the invention is to prevent the fume from passing along the filter without passing through the latter. To this end, the article for smokers according to the invention, comprising a duct for tobacco smoke into which a filter is introduced, is characterized by the fact that at least one longitudinal section of the wall of said duct is in contact with at least one longitudinal section of the peripheral wall of said filter disposed in said duct, so as to form an airtight seal for all fluids between these two wall sections and thus to force all smoke to pass through the filter before reaching the outlet of said leads.

La fig. 6 est une vue en coupe partielle; semblable ä celle de la fig. 2, repr6sentant une autre forme d'execution, constitu6e par un fume-cigarette. La fig. 7 est une vue en perspective repr6sen- tant un filtre destin6 ä etre utilis6 avec 1e fume- cigarette repr6sent6 ä la fig. 6. fig. 6 is a partial sectional view; similar to that of fig. 2, representing another form of execution, consisting of a cigarette holder. fig. 7 is a perspective view showing a filter for use with the cigarette holder shown in FIG. 6.

La fig. 8 est une vue en coupe partielle, semblable ä celle de la fig. 2, dune autre forme d'execution de 1'objet de Pinvention. Dans la description suivante, an a d6crit Pinvention comme appliqu6e ä un fume- cigarette, ä titre d'exemple. Toutefois, il doit etre bien entendu que 1'invention peut etre 6galement appliqu6e ä des fume-cigare, ä des pipes et ä tous autres articles pour fumeurs. fig. 8 is a partial cross-sectional view, similar to that of FIG. 2, of another form of execution of the object of the invention. In the following description, the invention has been described as applied to a cigarette holder, by way of example. However, it should be understood that the invention can also be applied to cigar holders, pipes and all other smokers' articles.

Revenant au dessin, an _voit que 1e fume- cigarette repr6sent6 en 10 comprend une embou- chure 12 et une extr6mite 14 mont6e dune maniere amovible sur 1'embouchure par frotte- ment dans 1e cas des fig. 2 et 4; ou encore par vissage dann 1e cas de la fig. 6. L'embouchure 12 et l'extr6mit6 14 peuvent etre 6tablies en tonte matiere appropriee teile qu'une matiere plastique ou un m6tal; de pr6ference, Pembouchure 12 est en une matiere plastique et 1'extr6mit6 14 en m6ta1. Returning to the drawing, it is seen that the cigarette holder shown at 10 comprises a mouthpiece 12 and an end 14 removably mounted on the mouthpiece by friction in the case of FIGS. 2 and 4; or by screwing in the first case of FIG. 6. Mouthpiece 12 and end 14 may be made of any suitable material such as plastic or metal; preferably, the mouth 12 is made of a plastic material and the end 14 of metal.

Dans la forme d'ex6cution repr6sent6e aux fig. 1 ä 3, 1'embout et 1'extr6mit6 du fume- cigarette 10 forment des 616ments ä paroi mince et d6finissent un conduit 28 pour la fum6e. Dans ce conduit 28 est plac6 un filtre 20 destin6 ä. effectuer 1e filtrage de la fumee qui 1e traverse. Le'filtre 20 est amovible et, pour permettre d'y acc6der, l'extr6mit6 14 est mont6e dune maniere amovible sur l'embout 12 par 1'interm6diaire dune virole 22 solidaire de 1'embout 12 et p6n6- trant ä frottement dans 1'extremit6 14 du fume- cigarette 1e long de la surface int6rieure de cette extr6mit6, de maniere ä assurer le maintien en Position correcte permanente de 1'embout par rapport ä 1'extr6mit6. In the form of execution represented in FIGS. 1-3, the mouthpiece and the end of the cigarette holder 10 form thin-walled members 616 and define a conduit 28 for the smoke. In this conduit 28 is placed a filter 20 destin6 ä. filter the smoke passing through it. The filter 20 is removable and, to allow access to it, the end 14 is mounted in a removable manner on the end piece 12 by means of a ferrule 22 integral with the end piece 12 and penetrating frictionally into 1 end 14 of the cigarette holder along the inner surface of this end, so as to ensure that the mouthpiece is maintained in the permanent correct position with respect to the end.

0n peut disposer une cigarette 15 dans 1'ouverture 24 de 1'extr6mit6 14 et, lorsqu'elle est allum6e et que 1e fumeur aspire par 1'extr6mit6 ouverte 26 de 1'embout, la fum6e traverse 1e conduit 28 pr6vu ä cet effet ä 1'int6rieur du fume- cigarette ä paroi mince. Lorsque la fumee tra verse 1e conduit 28, elle p6netre Jans 1e filtre 20 comportant, comme repr6sent6, une enveloppe 30 contenant une matiere filtrante appropri6e teile que des 616ments de gei de silice. A cigarette 15 can be placed in the opening 24 of the end 14 and, when it is lit and the smoker inhales through the open end 26 of the mouthpiece, the smoke passes through the conduit 28 provided for this purpose. the inside of the thin-walled cigarette holder. As the smoke passes through conduit 28, it enters filter 20 having, as shown, an envelope 30 containing suitable filter material such as silica gel elements.

L'enveloppe 30 est perforee ä son extr6mit6 32 et 1'extr6mit6 oppos6e de cette enveloppe est pourvue d'un fond perfor6 34. Ces perforations permettent ä la fum6e de traverser 1e filtre. Le fume-cigarette represent6 comporte un 6jec- teur de cigarette qui pr6sente un organe 17 en forme de L mont6 dans 1e conduit 28 pour la fumee et dont une Partie longitudinale 19 est susceptible de coulisser ä 1'int6rieur de la paroi de 1'extr6mit6 14. Un organe de commande 21 est dispos6 ä 1'ext6rieur de 1'extr6mit6 14, de maniere ä pouvoir coulisser sur cette derniere, cet organe 6tant reli6 ä Porgane 17 pour etre deplac6 solidairement avec ce dernier, cette liaison 6tant assuree par un rivet 23, traversant une ferste 25 s'6tendant longitudinalement dans la paroi de ladite extremit6 14. The envelope 30 is perforated at its end 32 and the opposite end of this envelope is provided with a perforated bottom 34. These perforations allow the smoke to pass through the filter. The cigarette holder represented comprises a cigarette ejector which has an L-shaped member 17 mounted in the pipe 28 for the smoke and of which a longitudinal part 19 is able to slide inside the wall of the end. 14. A control member 21 is disposed outside the end 14, so as to be able to slide on the latter, this member being connected to the member 17 to be moved integrally with the latter, this connection being ensured by a rivet 23, passing through a ferste 25 extending longitudinally in the wall of said end 14.

Ainsi, Porgane de commande 21 peut cou- lisser entre sa Position de repos repr6sentee ä la fig. 2 et une autre Position dans laquelle 1e rivet 23 vieret en contact avec 1'extr6mit6 ext6rieure de la ferste 25 de telle maniere que 1'organe 17 passe de la Position repr6sentee ä la fig. 2 ä une Position dans laquelle il afeure Pouverture 24 de 1'extr6mit6 14 en repoussant ainsi 1e bout de cigarette tenu dans cette ouverture pour 1e faire tomber. Thus, the control member 21 can slide between its rest position shown in FIG. 2 and another position in which the rivet 23 comes into contact with the outer end of the strap 25 so that the member 17 moves from the position shown in FIG. 2 at a position in which it bares the opening 24 of the end 14 thereby pushing the cigarette end held in this opening to fall.

Comme an 1e voit ä la fig. 2, 1e conduit pour la fum6e comporte une Partie cylindrique 36 relativement longue et une Partie de forme tronconique 38. Pour empecher de la fumee non filtr6e de passer entre la paroi du filtre 20 et la paroi du conduit filtrant, 1e filtre comporte de meme une Partie cylindrique 40, dont 1e dia- metre est 16gerement plus Petit que celui de la Partie 36, ainsi qu'une Partie tronconique 42. Avec une telle disposition des pieces, il sufät d'introduire 1e filtre dans 1e conduit et de 1e d6placer dans 1e sens longitudinal du fume- cigarette, ce qui se fait facilement, jusqu'ä ce que la Partie tronconique 42 du filtre vienne s'enga- ger ou se coincer dans la Partie tronconique 38 du fume-cigarette en assurant un joint herm6- tique avec ce dernier et en empechant ainsi tonte fumee de passer entre Penveloppe 30 du filtre et 1e fume-cigarette. Par suite, il est impos- sible que la fum6e passe 1e long du filtre 20 de telle sorte que 1'on est sür que tonte la fumee arrivant jusqu'au fumeur a bien 6t6 filtree. As seen in fig. 2, the smoke duct has a relatively long cylindrical portion 36 and a tapered portion 38. To prevent unfiltered smoke from passing between the filter wall 20 and the filter duct wall, the filter likewise has a Cylindrical part 40, whose diameter is slightly smaller than that of Part 36, as well as a frustoconical part 42. With such an arrangement of the parts, it suffices to introduce the filter into the duct and to move it into the longitudinal direction of the cigarette holder, which is easily done, until the tapered part 42 of the filter engages or gets stuck in the tapered part 38 of the cigarette holder, ensuring a hermetic seal with the latter and thereby preventing the smoke from passing between the envelope 30 of the filter and the cigarette holder. As a result, it is impossible for the smoke to pass along the length of the filter 20 so that it is certain that all the smoke reaching the smoker has been filtered.

Les fig. 4 et 5 representent une variante dans laquelle 1e conduit 28' prevu pour la fumee comporte deux Parties ou trongons de section droite sensiblement constante 36' et 39', ainsi qu'une Partie ou trongon interm6diaire de forme tronconique 38. Le filtre represent6 ä Part ä la fig. 5 pr6sente une forme semblable et, lorsque la petite Partie 44' de section droite constante a 6t6 introduite dans 1e conduit de fumee 28', an peut facilement repousser 1e filtre en direction de l'extremit6 26' de 1'embout 12' jusqu'ä ce que la Partie tronconique 42' du filtre soit 6troite- ment en Prise avec la Partie tronconique 38' du conduit pr6vu pour la fum6e, de maniere ä supprimer ainsi tont jeu entre la paroi du filtre et celle de ce conduit, ce qui assure que tonte la fum6e passe ä 1'int6rieur du filtre 20'. Figs. 4 and 5 represent a variant in which the first pipe 28' provided for the smoke comprises two Parts or sections of substantially constant cross section 36' and 39', as well as an intermediate Part or section of frustoconical shape 38. The filter shown separately in fig. 5 has a similar shape and, when the small portion 44' of constant cross-section has been inserted into the flue pipe 28', the filter can easily be pushed back towards the end 26' of the mouthpiece 12' as far as that the frustoconical part 42' of the filter is closely engaged with the frustoconical part 38' of the duct provided for the smoke, so as to eliminate any play between the wall of the filter and that of this duct, which ensures that all the smoke passes inside the filter 20'.

Les fig. 6 et 7 repr6sentent une troisieme forme d'ex6cution dans laquelle 1'embout 12" du fume-cigarette 10" comporte un conduit de fumee 28" pr6sentant une Partie terminale de forme tronconique ou en entonnoir 38" pr6sen- tant un filetage 50 dans lequel est vissee 1'extr6- mit6 14 ". Figs. 6 and 7 show a third embodiment in which the mouthpiece 12" of the cigarette holder 10" comprises a flue 28" having a terminal part of frustoconical or funnel shape 38" having a thread 50 in which is screwed at the 14" end.

Le conduit de fumee represente en 28" comprend encore une Partie assez longue de section droite constante 39 ". La fig. 7 repr6sente un filtre destine ä etre utilise avee 1e fume- cigarette 10" et ce filtre pr6sente ä peu pres la meme conformation que les filtres 20 et 20', sauf en ce qui concerne la Partie voisine de 1'extr6mit6 arriere, c'est-ä-dire 1ä Partie 42"; celle-ci est de forme tronconique et elle est solidaire dune Partie 44" de section droite constante, dopt la longueur est relativement importante, cette derniere Partie du filtre etant destin6e ä etre introduite facilement dans la Partie 39" du conduit de fum6e de section droite egalement constante. Par suite, lorsque 1e filtre 20" est introduit dans 1e conduit de fum6e 28", an peut facilement faire avancer 1e filtre Jans 1e fume-cigarette 10" jusqu'ä ce que la Partie tronconique 42" soit introduite dans la Partie tronconique 38" du conduit de fum6e de fagon ä former un joint herm6tique et se coince Jans celle-ci, de mani6re ä supprimer tont jeu 6ventuel entre la paroi du filtre et la paroi interieure du fume-cigärette, ce qui oblige en tonte certitude tonte la fumee ä traverser 1e filtre. The flue represented in 28" still includes a fairly long part of constant straight section 39". fig. 7 shows a filter intended for use with the 10" cigarette holder and this filter has approximately the same conformation as the filters 20 and 20', except for the part adjacent to the rear end, that is i.e. 1st Part 42"; this is of frustoconical shape and it is integral with a Part 44" of constant cross section, adopts the length is relatively large, this last Part of the filter being intended to be easily introduced into the Part 39" of the flue of straight section also constant. As a result, when the 20" filter is inserted into the 28" smoke duct, one can easily advance the filter through the 10" cigarette holder until the 42" tapered portion is introduced into the tapered portion 38" of the smoke duct so as to form a hermetic seal and gets stuck in it, so as to eliminate any possible play between the wall of the filter and the interior wall of the cigarette holder, which obliges in your certainty cut the smoke to pass through the filter.

La forme d'ex6cution representee ä la fig. 8 est prevue dans 1e cas de Pusage de filtres ne presentant pas de Partie conique, dans un fume- RTIID="0003.0273" WI="13" HE="4" LX="1033" LY="617"> cigarette n'en presentant pas non plus. Le fume- cigarette 10"' comprend un embout 12" reli6 ä 1'extremit6 W', par exemple, par vissage en 50 "'. Le conduit, m6nag6 pour la fumee en 28" dans 1'embout, comporte au voisinage de ce filetage 50"' une Partie cylindrique 36" qui est sensiblement plus longue que 1e filtre 20"'. Etant dönn6 la longueur de cette Partie cyhn- drique 36"', lorsque 1e filtre 20"'y est introduit; il ne peut venir en contact herm6tique avec la paroi int6rieure de Pembout saus disparaitre entierement dans cette Partie. Pour 6viter cet inconv6nient, an introduit une garniture inter- m6diaire 52 dans la Partie cylindrique 36"' du conduit 28"' pour la fum6e. Cette garniture interm6diaire 52 est conform6e de maniere ä venir en contact 6troit avec la paroi cylindrique 36 "' empechant la fumee de passer entre la garniture 52 et la paroi. L'extr6mit6 42" de la garniture 52 opposee au filetage 50"' est de forme tröneonique et peut venir en Prise avec 1'extremit6 du filtre 20"' qui y est introduit, ce qui assure 1'herm6ticite du joint et empeche la fumee de passer 1e long du filtre sans 1e traverser. The form of execution represented in FIG. 8 is provided in the case of the use of filters not having a conical part, in a cigarette smoker not presenting either. The 10" cigarette holder comprises a 12" mouthpiece connected to the end W', for example, by screwing at 50 "'. The conduit, provided for the smoke at 28" in the mouthpiece, comprises thread 50"' a Cylindrical Part 36 which is substantially longer than the filter 20"'. introduced; it cannot come into hermetic contact with the inner wall of the mouthpiece without disappearing entirely in this part. This intermediate gasket 52 is shaped so as to come into close contact with the cylindrical wall 36'', preventing smoke from passing between the gasket 52 and the wall. The 42" end of the packing 52 opposite the 50" thread is of tröneonic shape and can come into engagement with the end of the 20" filter which is inserted therein, which ensures the hermeticity of the joint and prevents smoke. to pass along the filter without crossing it.
