Description

Sigarettfilter. Cigarette filter.

Foreliggende oppfinnelse angår et sigarettfilter som enten danner en med sigaretten sammenhengende ende, eller som har form av en del av et sigarettmunnstykke, og som muliggjor omdanning av roken fra den brennende tobakk til en aromatisk r6k ved å tvinge den i kon-takt med aromatiske væsker. The present invention relates to a cigarette filter which either forms an end connected to the cigarette, or which has the form of a part of a cigarette mouthpiece, and which enables the transformation of the smoke from the burning tobacco into an aromatic smoke by forcing it into contact with aromatic liquids .

Det har lenge vært kjent at en enkel impregnering av et sigarettfilter med aromatiske væsker er utilfredsstillende som middel for å gi sigarettrSken smak, på grunn av den hurtige fordampning av væsken fra filteret. Det har vært benyttet flere forskjellige anordninger for å bibeholde væsken i filteret uten fordampning inntil sigaretten skal brukes. Slike anordninger omfatter en enkel, temmelig stor kap- It has long been known that a simple impregnation of a cigarette filter with aromatic liquids is unsatisfactory as a means of giving cigarette smoke flavor, due to the rapid evaporation of the liquid from the filter. Several different devices have been used to retain the liquid in the filter without evaporation until the cigarette is to be used. Such devices include a simple, fairly large cap-

sel som kan knuses ved trykk når det er 5nskelig å frigjøre væsken; og seals that can be crushed by pressure when it is desired to release the liquid; and

andre anordninger slik som granulert aktivert kull hvori smaksmidlene er absorbert inntil de trekkes ut av roken ; og en væske-ugjennomtrenge-lig, men rok-gjennomtrengelig membran som omgir en væske-impregnert del av det absorberende filtermateriale. Fordelene med foreliggende oppfinnelse i forhold til disse tidligere kjente anordninger ligger i at omfanget av frigjøringen av aromatisk væske i betydelig grad kan reguleres av rokeren fordi det benyttes et stort antall meget små kapsler som brister ved trykk, og som inneholder væsken, og et varier-ende antall av disse kan knuses på en gang avhengig av det trykk som påfores filteret. other devices such as granulated activated carbon in which the flavoring agents are absorbed until they are extracted from the rook; and a liquid-impermeable but smoke-permeable membrane surrounding a liquid-impregnated portion of the absorbent filter material. The advantages of the present invention in relation to these previously known devices lie in the fact that the extent of the release of aromatic liquid can be regulated to a considerable extent by the smoker because a large number of very small capsules are used which burst under pressure, and which contain the liquid, and a vari- end number of these can be crushed at once depending on the pressure applied to the filter.

Ifolge foreliggende oppfinnelse er det tilveiebragt et sigarettfilter omfattende en deformerbar sylindrisk hylse inneholdende absorberende filtermateriale og inneholdende aromatisk flytende materiale som kan frigjores fra filteret og som holdes i dette ved hjelp av en trykk-bristbar membran, kjennetegnet ved at det flytende materialet inneholdes i ot stort antall meget små kapsler med vegger som utgjores av nevnte membran. According to the present invention, a cigarette filter is provided comprising a deformable cylindrical sleeve containing absorbent filter material and containing aromatic liquid material which can be released from the filter and which is held in it by means of a pressure-rupturable membrane, characterized in that the liquid material is contained in a large number of very small capsules with walls made up of said membrane.

Hensikten med oppfinnelsen er å gi rokeren et valg mellom ikke aromatisk rok og mer eller mindre aromatisk rok. Storrelsen på trykket i forhold til tiden er en måte å bestemme dette på. Trykket kan utoves i oket grad med Snskede tidsintervaller under roking av sigaretten, eller det kan forst utoves ved slutten av rokingen. The purpose of the invention is to give the smoker a choice between non-aromatic rok and more or less aromatic rok. The size of the pressure in relation to time is one way of determining this. The pressure can be exerted to an increasing degree at desired time intervals during smoking of the cigarette, or it can only be exerted at the end of smoking.

Filteret omfatter en hylse som kan være en sammenhengende forlengelse av hylsen som omgir tobakken, eller det kan festes til denne. I hylsen er det to i aksiell avstand fra hverandre anbragte propper av porost materiale, f.eks. cellulosefibre, og mellom disse er det anbragt en knusbar sammensetning som omfatter meget små kapsler som inneholder aromatisk væske. The filter comprises a sleeve which can be a continuous extension of the sleeve surrounding the tobacco, or it can be attached to it. In the sleeve, there are two plugs of porous material placed at an axial distance from each other, e.g. cellulose fibres, and between these is placed a breakable composition comprising very small capsules containing an aromatic liquid.

Diameteren på kapslene kan med fordel være i området 10-1500 mikron og kan fordeles etter storrelse eller innhold. Diameteren på kapsler i sigarettfilter bor ikke overskride 1500 mikron, idet storre kapsler har en tendens til å hindre roken i å passere gjennom filteret. The diameter of the capsules can advantageously be in the range of 10-1500 microns and can be distributed according to size or content. The diameter of capsules in cigarette filters should not exceed 1500 microns, as larger capsules tend to prevent the smoke from passing through the filter.

Kapslenes vegger kan lages av gelatin-gummi-arabicum-kompleks, gelatin-carragenkomplekser, utfelte succinylerte gelatiner, etyl-cellulose eller andre materialer. Enhver standard fremgangsmåte for innkapsling, slik som den som i det folgende eksempel er beskrevet for fremstilling av kapslene, kan benyttes. The walls of the capsules can be made of gelatin-gum arabicum complex, gelatin-carrageenan complexes, precipitated succinylated gelatins, ethyl cellulose or other materials. Any standard method for encapsulation, such as that described in the following example for producing the capsules, can be used.

Kapslene kan blandes med små partikler som kan være uvirk-somme eller som kan tilveiebringe en tilleggsfiltreringsvirkning,. slik som f.eks. aktivert trekull. Filteret kan omfatte to forskjellige innkapslede substanser som samvirker når disse kapslene revner. Det relative forhold mellom faste partikler og kapsler kan varieres i hen-hold til hvilken effekt som onskes oppnådd. The capsules can be mixed with small particles which can be inactive or which can provide an additional filtering effect. such as e.g. activated charcoal. The filter can comprise two different encapsulated substances which interact when these capsules burst. The relative ratio between solid particles and capsules can be varied according to the desired effect.

Kapslene bor fortrinnsvis inneholde en oljeaktig, aromatisk væske som utgjor ca. 90 vektprosent av hele kapselen. Den oljeaktige væsken utloses ved at materialet i kapselens vegg revner. Den oljeaktige væsken kan være en blanding av oljer eller dispersjoner av faste partikler i oljer. Hver kapsel kan inneholde forskjellige substanser. Mentol er den foretrukne substansen som omgis av den stive, revnbare, somlose kapselen, men den kan også inneholde andre substanser slik som olje av peppermynte, cola, koffein, olje av anis, coca, olje av nelliker, parfyme og lignende. Slike materialer som svovelsyre, natriumhydroksyd og bestemte aminer som selektivt utvasker fra tobakks-røken substanser som er helseskadelige for rokeren, kan også anvendes. Klorofyll og listerin kan anvendes for å forhindre dårlig ånde. Hydro-genperoksyd kan anvendes for å hvitne eller bleke rokerens tenner. The capsules should preferably contain an oily, aromatic liquid that makes up approx. 90 percent by weight of the entire capsule. The oily liquid is released when the material in the capsule's wall cracks. The oily liquid can be a mixture of oils or dispersions of solid particles in oils. Each capsule can contain different substances. Menthol is the preferred substance surrounded by the rigid, breakable, somless capsule, but it may also contain other substances such as oil of peppermint, cola, caffeine, oil of anise, coca, oil of cloves, perfume and the like. Such materials as sulfuric acid, sodium hydroxide and certain amines which selectively wash out from the tobacco smoke substances which are harmful to the health of the smoker, can also be used. Chlorophyll and listerine can be used to prevent bad breath. Hydrogen peroxide can be used to whiten or bleach the smoker's teeth.

Det folgende eksempel illustrerer en fremgangsmåte for inn-kapslingen. The following example illustrates a procedure for the encapsulation.

EksempelExample

l80 ml med hoy kvalitet, syre-ekstrahert, svineskinn-gelatin (285 - 305 Bloom-styrke, isoelektrisk punkt pH 8 - 9) og l80 ml 11$ opplosning av gummi arabicum ble blandet med 56O ml vann ved omtrent 35°-40°C i et 1500 ml beger. 180 ml of high quality, acid-extracted, pigskin gelatin (285 - 305 Bloom strength, isoelectric point pH 8 - 9) and 180 ml of 11% gum arabic solution were mixed with 560 ml of water at about 35°-40° C in a 1500 ml beaker.

Det ble ikke foretatt noen regulering av pH. Prepareringen ble omrort ved hjelp av en turbinskovl og en skvalpeplate. Det ble tilsatt 260 g mentol ved 35°C°6frembragt små dråper med en indre dia-meter på 1000-1500 mikron. No adjustment of pH was made. The preparation was stirred using a turbine blade and a flapper plate. 260 g of menthol were added at 35°C°6 producing small droplets with an inner diameter of 1000-1500 microns.

Prepareringen ble sakte avkjolt under konstant omroring til en temperatur på 25°C. Prepareringen ble deretter bråkjolt i et isbad, og 10 ml av en 25$ opplosning av glutaraldehyd ble tilsatt. Det ble deretter foretatt en omroring i 16 timer. Kapslene ble vasket to ganger med vann og deretter omrSrt i 15 minutter i en opplflsning av 2.5 roi med trimetyl-talg-ammoniumklorid i 500 ml vann. 20 ml hydro-genert talk-aminacetat ble tilsatt og omr5ringen fortsatte i en time. Kapslene ble vakuumfiltrert og deretter torket. The preparation was slowly cooled with constant stirring to a temperature of 25°C. The preparation was then quenched in an ice bath, and 10 ml of a 25% solution of glutaraldehyde was added. Stirring was then carried out for 16 hours. The capsules were washed twice with water and then stirred for 15 minutes in a solution of 2.5 r of trimethyl tallow ammonium chloride in 500 ml of water. 20 ml of hydrogenated talc amine acetate was added and stirring was continued for one hour. The capsules were vacuum filtered and then dried.
