Description

Sigarett. Cigarette.

Foreliggende oppfinnelse angår en sigarett. The present invention relates to a cigarette.

Skjønt man ennå ikke har noe fullgyl-dig bevis for sammenhengen mellom cancer og andre sykdommer, og sigarettrøking, kan det anses som sannsynlig at overdrevet røking vil medføre en bestemt forøkelse av mulighetene for å pådra seg cancer eller andre alvorlige sykdommer. Although there is still no valid evidence for the connection between cancer and other diseases, and cigarette smoking, it can be considered likely that excessive smoking will lead to a definite increase in the chances of contracting cancer or other serious diseases.

En del autoriteter heller til den an-skuelse at et høyt tjæreinnhold i den røk som innåndes under røking av en sigarett, forårsaker en skadelig innvirkning på stor-røkere. Tjære kan som påvist forminskes eller elimineres ved riktig filtrering, men filtreringsgraden, som beror på lengden av filterfibrene, og på hvor tett de er sammen-presset, må begrenses slik at sigaretten ikke trekker dårlig og blir vanskelig å røke. Some authorities prefer the view that a high tar content in the smoke inhaled while smoking a cigarette causes a harmful effect on heavy smokers. As has been proven, tar can be reduced or eliminated by proper filtration, but the degree of filtration, which depends on the length of the filter fibers and how tightly they are pressed together, must be limited so that the cigarette does not smoke badly and becomes difficult to smoke.

Dessuten er andre autoriteter av den oppfatning at forbrenningstemperaturen i flammen eller i det minste temperaturen av den røk som innåndes av røkeren, har direkte innflytelse på de skadelige virkninger som påstås forårsaket ved røking. Disse autoriteter mener at en vesentlig for-minskelse av temperaturen av den inn-åndete røk for en stor del foirminsker eller eliminerer forværrende virkninger på hel-breden. Moreover, other authorities are of the opinion that the temperature of combustion in the flame, or at least the temperature of the smoke inhaled by the smoker, has a direct influence on the harmful effects alleged to be caused by smoking. These authorities believe that a substantial reduction in the temperature of the inhaled smoke to a large extent reduces or eliminates worsening effects on health.

Andre autoriteter er av den oppfatning Other authorities are of that opinion

at skadelige biprodukter frambringes i røken på grunn av ufullstendig forbren-ning, og at de påståtte skadelige virkninger av røking ville reduseres eller elimineres, dersom det ble tilført gloen mer oksygen that harmful by-products are produced in the smoke due to incomplete combustion, and that the alleged harmful effects of smoking would be reduced or eliminated if more oxygen were added to the glow

med forbrenningsluften. I den bakerste del av gloen blir oksygentilførslen i en vanlig sigarett redusert på grunn av at oksygenet i den innsugete luft forbrukes i den for-reste del av gloen. Forbrenningen blir således .ufullstendig i den bakerste del av gloen.. with the combustion air. In the rear part of the glow, the oxygen supply in a normal cigarette is reduced because the oxygen in the inhaled air is consumed in the front part of the glow. The combustion is therefore incomplete in the rear part of the ember.

Oppfinnelsen har til formål å fram-bringe en sigarett i hvilken mer oksygen er tilgjengelig i den bakerste del av gloen, slik at det oppnås en mer fullstendig for-brenning på dette sted. The purpose of the invention is to produce a cigarette in which more oxygen is available in the rear part of the ember, so that a more complete combustion is achieved in this place.

Et ytterligere formål med oppfinnelsen er å framstille en sigarett som tillater anvendelse av et mer effektivt filter. Dette formål oppfylles ved at sigaretten har et omslag med et antall utpressinger, som er så store at de bryter omslagets fibre og derved øker dettes porøsitet uten å perforere det. A further object of the invention is to produce a cigarette which allows the use of a more efficient filter. This purpose is fulfilled by the cigarette having a cover with a number of extrusions, which are so large that they break the fibers of the cover and thereby increase its porosity without perforating it.

Det er riktignok kjent fra U.S. patent-skrift nr. 2 304 009 å anvende et perforert sigarettpapir som omslag for en sigarett, slik at denne er utført med et antall gjennom-gående hull. Dette medfører dog den ulempe at tobakken får en tendens til å krype ut gjennom huller i omslaget, og dessuten får sigarettens ytterside et mindre tiltalende utseende. Disse ulemper unngås ved oppfinnelsen som dessuten gir sigaretten en ruere ytterside, som øker friksjonen mot røkerens fingre og hindrer at fingrene glir, slik at røkeren ikke risikerer å brenne seg. It is admittedly known from the U.S. patent document no. 2 304 009 to use a perforated cigarette paper as a cover for a cigarette, so that this is made with a number of through holes. However, this entails the disadvantage that the tobacco has a tendency to creep out through holes in the cover, and furthermore the outside of the cigarette takes on a less appealing appearance. These disadvantages are avoided by the invention, which also gives the cigarette a rougher exterior, which increases the friction against the smoker's fingers and prevents the fingers from slipping, so that the smoker does not risk burning himself.

Oppfinnelsen skal forklares nærmere under henvisning til tegningen, på hvilken: The invention shall be explained in more detail with reference to the drawing, in which:

Fig. 1 viser en utførelsesform for en sigarett ifølge oppfinnelsen, sett fra siden. Fig. 2 i større målestokk et delsnitt efter linjen 2-2 på fig. 1. Fig. 3 i ennu større målestokk en del av et sigarettomslag ifølge oppfinnelsen, og Fig. 1 shows an embodiment of a cigarette according to the invention, seen from the side. Fig. 2 on a larger scale, a partial section along the line 2-2 in fig. 1. Fig. 3 on an even larger scale part of a cigarette wrapper according to the invention, and

fig. 4 skjematisk en hensiktsmessig an-ordning til forming av papiromslaget ifølge oppfinnelsen. fig. 4 schematically shows a suitable device for forming the paper cover according to the invention.

Som vist på fig. 1 har sigaretten 10 et omslag 11, som er gaufrert, slik som det senere skal beskrives mere detaljert. Om ønskes kan sigaretten være forsynt med et passende filter, som på fig. 1 er betegnet med 12. As shown in fig. 1, the cigarette 10 has a cover 11, which is embossed, as will be described in more detail later. If desired, the cigarette can be provided with a suitable filter, as in fig. 1 is denoted by 12.

Man har funnet at papirets porøsitet kan økes i regulerbar grad ved å danne en rekke utpressinger på papiroverflaten ved gaufering eller ved en annen fremgangsmåte, hvilke utpressinger er tilstrekkelig store til å avbryte papirets fibere, uten at det oppstår huller i papiret. It has been found that the porosity of the paper can be increased to a controllable degree by forming a series of extrusions on the paper surface by gouging or by another method, which extrusions are sufficiently large to interrupt the fibers of the paper, without creating holes in the paper.

De fremspring som anvendes til å tilveiebringe utpressingene i papiret, skal ha en slik høyde at papiret i utpressingene de-formeres ved strekking og fibrene brytes. Strekkingen skal være så kraftig at papiret ikke vender tilbake til sin opprinnelige plane form, men ikke så sterkt at det oppstår huller i papiret. Porøsiteten i omslaget økes ved at de strukkete deler er tynnere enn de u-strukkete deler, hvorved luft let-tere kan passere gjennom de tynnere deler enn gjennom de tykkere deler. Porøsiteten økes dessuten ved at en del av papirfibrene brytes under strekkingen, og de strukkete deler yter således mindre strømningsmot-stand. The protrusions used to provide the extrusions in the paper must be of such a height that the paper in the extrusions is deformed by stretching and the fibers break. The stretching should be so strong that the paper does not return to its original flat shape, but not so strong that holes appear in the paper. The porosity of the cover is increased by the fact that the stretched parts are thinner than the unstretched parts, whereby air can pass more easily through the thinner parts than through the thicker parts. Porosity is also increased by the fact that part of the paper fibers are broken during stretching, and the stretched parts thus offer less flow resistance.

Fig. 2 viser sigaretten 10 forsynt med det gaufrerte omslag 11, som inneslutter den skårne tobakksfylling 13. Porøsiteten av papiromslaget 11 er ifølge oppfinnelsen blitt øket ved gaufrering, der som vist omfatter dannelsen av en rekke utpressinger 14 på omslagets overflate. Som det ennu tydeligere sees på fig. 3 er utpressingene 13 adskilt ved furer 15, i hvis bunn papiret er tynnere. Fig. 2 shows the cigarette 10 provided with the embossed cover 11, which encloses the cut tobacco filling 13. According to the invention, the porosity of the paper cover 11 has been increased by embossing, which, as shown, includes the formation of a series of extrusions 14 on the surface of the cover. As can be seen even more clearly in fig. 3, the extrusions 13 are separated by furrows 15, at the bottom of which the paper is thinner.

Vanlige gaufreringsmaskiner bestemt til å forbedre utseendet av papir, folier og annet arkmateriale er vel kjent. Gaufreringen består i å danne et antall tettliggende forhøyninger eller utpressinger som bryter den glatte papiroverflate, og som hittil er blitt anvendt på grunn av sin estetiske effekt. Conventional embossing machines designed to improve the appearance of paper, foils and other sheet material are well known. The embossing consists in forming a number of closely spaced elevations or extrusions which break the smooth paper surface, and which have hitherto been used because of their aesthetic effect.

På fig. 4 er skjematisk vist hvorledes papiret, som anvendes til å danne omsla- In fig. 4 schematically shows how the paper, which is used to form cover-

get 11, kan formes til den ønskete gaufrerte tilstand i en vanlig gaufreringsmaskin med de to mot hverandre pressete valser, som er forsynt med det ønskete mønster. Som vist på denne figur mates papiret P inn mellom valsene 20 og 21, som roterer i den med pilene viste retning. Valsen 20 har overflaten utført med tettliggende utbuktninger 22, som er spredt langs periferien og get 11, can be formed into the desired corrugated state in a normal embossing machine with the two rollers pressed against each other, which are provided with the desired pattern. As shown in this figure, the paper P is fed between the rollers 20 and 21, which rotate in the direction shown by the arrows. The roller 20 has a surface made with closely spaced protrusions 22, which are spread along the periphery and

i valsens lengderetning langs det stykke av in the longitudinal direction of the roller along that part of

valsen som kreves for å behandle den the roller required to process it

ønskete papirbredde, som skal formes ifølge oppfinnelsen. Valsene 20 og 21 pres-ses sammen slik at fremspringene 22 presser papiret P inn i overflaten av valsen 21, som er utført av passende materiale, slik at papiret får den ønskete gaufrerte tilstand, som er vist efter passeringen gjennom valsene. desired paper width, which must be shaped according to the invention. The rollers 20 and 21 are pressed together so that the protrusions 22 press the paper P into the surface of the roller 21, which is made of suitable material, so that the paper gets the desired corrugated condition, which is shown after passing through the rollers.

Som det fremgår av fig. 3 er papiromslaget som resultat av gaufreringen uttynnet i de mellom utpressingene liggende furer, slik at papirets porøsitet er blitt øket på adskilte steder over hele overflaten, uten at det er oppstått huller i papiret. As can be seen from fig. 3, as a result of the embossing, the paper cover is thinned in the furrows lying between the extrusions, so that the paper's porosity has been increased in separate places over the entire surface, without any holes in the paper.

Man har nu funnet at papirfibrene ved gaufrering av vanlig sigarettpapir brytes mellom utpressingene, og at papirets porø-sitet på dette sted økes slik at luft kan trenge inn gjennom papiret til gloen for å forbedre dennes effektivitet og kanskje ennu viktigere, trenge inn bak gloen, slik at røken kjøles og den trekk som kreves til å røke en vanlig sigarett minskes. It has now been found that the paper fibers when embossing ordinary cigarette paper are broken between the squeezes, and that the paper's porosity at this point is increased so that air can penetrate through the paper to the ember to improve its efficiency and perhaps even more importantly, penetrate behind the ember, so that the smoke is cooled and the draft required to smoke a regular cigarette is reduced.

Det er klart at en sigarett utformet med et omslag som er gaufrert ifølge oppfinnelsen, gir bedre trekk enn en lignende sigarett utført med vanlig glatt papir, idet det ikke alene ved enden kommer luft inn. I dette tilfelle kan det anvendes et lengere og/eller mere tettpakket filter til en sigarett med et gaufrert omslag, enn det er tilfelle ved en vanlig sigarett bestemt til å røkes med samme trekk. Den forminskete suging som kreves til å røke sigaretten ifølge foreliggende oppfinnelse, tillater således en mere effektiv filtering enn det hittil har væt mulig å tilveiebringe, og dette er en av de viktigste egenskaper ved oppfinnelsen. It is clear that a cigarette designed with a wrapper that is embossed according to the invention provides better drafts than a similar cigarette made with ordinary smooth paper, as air does not enter only at the end. In this case, a longer and/or more densely packed filter can be used for a cigarette with a corrugated cover, than is the case with a normal cigarette intended to be smoked with the same puff. The reduced suction required to smoke the cigarette according to the present invention thus allows a more efficient filtering than has hitherto been possible to provide, and this is one of the most important properties of the invention.

Størrelsen og høyden av gaufreringen bestemmer papirets porøsitet, og jo høyere og tettere gaufreringen er utført, desto større blir porøsiteten. Høyden, størrelsen og tettheten av utpressingene kan lett bestemmes for hver gitt igarett med hensyn til dens lengde og diameter, sammenpak-ningsgraden og den skårne lengde av tobakken, samt også i noen utstrekning typen av den anvendte tobakk. Gaufreringsgraden kan derfor bestemmes av de egenskaper som kreves i vanlige sigaretter, så som filtrering, røkens temperatur o.s.v. The size and height of the embossing determine the porosity of the paper, and the higher and denser the embossing, the greater the porosity. The height, size and density of the squeezes can be easily determined for each given igarette with regard to its length and diameter, the degree of packing and the cut length of the tobacco, and also to some extent the type of tobacco used. The degree of corrugation can therefore be determined by the properties required in ordinary cigarettes, such as filtration, the temperature of the smoke, etc.

Det er tenkelig at det kan være ønsket å variere papirets porøsitet fra den ene ende av sigaretten til den annen. Når bare et lite stykke av sigaretten er røkt, kan det kreves mere oxygen enn når sigaretten er nesten helt konsumert. Av denne grunn kan gaufreringen utføres høyere eller tettere ved den ende av sigaretten som skal tennes, og avta mere eller mindre jevnt mot munnstykke-enden. It is conceivable that it may be desired to vary the porosity of the paper from one end of the cigarette to the other. When only a small piece of the cigarette is smoked, more oxygen may be required than when the cigarette is almost completely consumed. For this reason, the embossing can be made higher or denser at the end of the cigarette to be lit, and decrease more or less evenly towards the mouthpiece end.

En stor fordel ved sigaretten ifølge oppfinnelsen er dens utseende. I stedet for å forringe utseendet av sigaretten, slik som det har vært tilfelle ved tidligere med per-foreringer utførte sigaretter av denne art, forhøyer omslaget ifølge oppfinnelsen sigarettens utseende derved at denne for-synes med et gaufrert papir, som er lett å kjenne igjen, og estetisk i seg selv. A major advantage of the cigarette according to the invention is its appearance. Instead of detracting from the appearance of the cigarette, as has been the case with previous cigarettes of this type made with perforations, the cover according to the invention enhances the appearance of the cigarette by providing it with an embossed paper, which is easy to recognize , and aesthetic in itself.

En annen viktig egenskap ved oppfinnelsen består i den letthet med hvilken oppfinnelsen kan anvendes i vanlige sigarettmaskiner. Til gaufrering av vanlig sigarettpapir er det bare nødvendig å føre det mellom to mot hverandre pressete valser forsynt med det ønskete mønster. Disse valser kan føyes til i hver sigarettmaskin før eller efter påtrykningsstedet og umiddel-bart før formningen av selve sigaretten. Det kreves ingen annen endring av det foreliggende utstyr enn tilføyelsen av de to enkle gaufreringsvalser og en eller annen spennemekanisme som sikrer jevn gaufrering. Another important characteristic of the invention consists in the ease with which the invention can be used in ordinary cigarette machines. To emboss ordinary cigarette paper, it is only necessary to pass it between two pressed against each other rollers provided with the desired pattern. These rollers can be added to each cigarette machine before or after the pressing point and immediately before the shaping of the cigarette itself. No other change is required to the existing equipment than the addition of the two simple embossing rollers and some clamping mechanism that ensures uniform embossing.

I de fleste vanlige sigarettmaskiner utføres samtidig også trykningen av papiret. Når det ønskes å tilveiebringe avtag-ende porøsitet, kan dette lett utføres i et med avskjæringen synkronisert tempo på samme måte som den hvorpå trykkingen for tiden utføres. In most ordinary cigarette machines, the paper is also printed at the same time. When it is desired to provide diminishing porosity, this can easily be carried out at a pace synchronized with the cutting in the same manner as that at which the printing is currently carried out.

Fremstillingen av utpressingene som utgjør gjenstanden for oppfinnelsen, er ovenfor betegnet som gaufrering. Det er imidlertid klart at en hvilken som helst annen fremgangsmåte, hvor utbuktninger eller lignende utpregninger dannes i siga-rettpapiret med henblikk på å øke papirets porøsitet ved å bryte dettes fibre uten å perforere papiret, kan anvendes, og det i beskrivelsen og påstandene anvendte ut-trykk gaufrering omfatter derfor enhver måte eller fremgangsmåte som kan tilveiebringe den virkning i papiret som utgjør gjenstanden for oppfinnelsen. Som eksem-pel på oppfinnelsen kan følgende angivel-ser nevnes. Et normalt i handelen fore-kommende sigarettpapir med betegnelsen Ecusta 153 fremstilt av Ecusta Paper Divi-sion hos Olin Mathieson Chemical Corpo-ration, Pisgah Forest, North Carolina, ble gaufrert ved å føres i inngrep med en i hovedsaken konvensjonell gaufreringsvalse, forsynt med 26 fremspring per cm. hvorved utbuktningene er 0.127 mm høye. Gaufreringsvalsen ble presset under et trykk av 36 kg mot en mot trykks valse av Lucite. Pregevalsen hadde en diameter av 63.5 mm og mottrykksvalsen en diameter av 114.3 mm. Det anvendte papir ble ført mellom gaufreringsvalsen og mottrykksvalsen, hvorved valsens fremspring dannet tett spredte utbuktninger på papiroverflaten ved at fremspringene presset papiret inn i den relativt ettergivende overflate på mottrykksvalsen. Papirets porøsitet efter gaufreringen ble prøvet i en innen papirindu-strien vanlig porøsitetsmåler, i hvilken man observerte det antall sekunder luften behøver til å passere gjennom papiret for å løfte en vannsøyle til en bestemt høyde, og man fant derved en middelporøsitet på 20,2 sek./H til sammenligning med middel-porøsiteten av papiret før gaufreringen på 43,5 sek./H idet H er høyden av nevnte vannsøyle. The manufacture of the extrusions which constitute the object of the invention is referred to above as embossing. However, it is clear that any other method, in which bulges or similar protrusions are formed in the cigarette paper for the purpose of increasing the porosity of the paper by breaking its fibers without perforating the paper, can be used, and that in the description and claims used out -print embossing therefore includes any method or method that can provide the effect in the paper that constitutes the object of the invention. As an example of the invention, the following statements can be mentioned. A commercially available cigarette paper with the designation Ecusta 153 manufactured by the Ecusta Paper Division of Olin Mathieson Chemical Corporation, Pisgah Forest, North Carolina, was embossed by being brought into engagement with a mainly conventional embossing roll, provided with 26 projections per cm. whereby the protrusions are 0.127 mm high. The embossing roll was pressed under a pressure of 36 kg against a counter pressure roll of Lucite. The embossing roller had a diameter of 63.5 mm and the counter pressure roller a diameter of 114.3 mm. The used paper was passed between the embossing roller and the counter-pressure roller, whereby the protrusions of the roller formed closely spaced bulges on the paper surface by the protrusions pressing the paper into the relatively yielding surface of the counter-pressure roller. The porosity of the paper after embossing was tested in a porosity meter common in the paper industry, in which the number of seconds the air needs to pass through the paper to lift a column of water to a certain height was observed, and an average porosity of 20.2 sec was found ./H for comparison with the average porosity of the paper before embossing of 43.5 sec./H, H being the height of said water column.

Claims (6)

1. Sigarett med et av fibermateriale framstilt omslag av gaufrert papir, karakterisert ved at utpresningene er av en slik størrelsesorden at de bryter omslagets fibre og derved øker dettes porøsi-tet uten å perforere det.1. Cigarette with a wrapper of corrugated paper made of fibrous material, characterized in that the extrusions are of such a magnitude that they break the fibers of the wrapper and thereby increase its porosity without perforating it. 2.
