Den foreliggende opfindelse angår en tobakspung med en kasse-formet posedel og af den i indledningen til krav 1 angivne art samt en fremgangsmåde til fremstilling af tobakspungen.The present invention relates to a tobacco purse having a box-shaped bag portion and of the kind set forth in the preamble of claim 1, and to a method of making the tobacco purse.
5 Sådanne tobakspunge er almindeligt kendte, idet mellemlaget normalt er af papir og eventuelt har tværgående rillelinier til dannelse af den indadvendende bundfals. Mellemlaget har endvidere en sådan bredde, at den kan foldes ned langs siderne af den i fyldt tilstand kasseformede tobakspung, hvorfor mel-10 lemlaget i forvejen har to langsgående rille- eller perfo reringslinier til foldning af papirlaget ved tobakspungens langsgående kant til dannelse af sidefladerne, således at disse derved formede sideflige fra hver side når ned til omkring midten af sidefladerne. Desuden skal der i hvert mellemlags-15 arkemne udstanses bundtrekanter for at muliggøre foldning ved pungens bund. Disse linier og udstansninger medførere at mellemlagsarkemnerne skal fremstilles i en særskilt proces og enkeltvis indføres mellem det ydre og det indre plastfolde-lag, der tilføres fra rullen. Det har vist sig, at en sådan 20 tobakspung er vanskelig at rejse for fyldning hos tobaksfa brikanten, idet de på fyIdemaskinen dertil beregnede gribe-fingre ikke altid former tobakspungen korrekt, idet sidefligene vil have tendens til at knække udad og omforme posen set i snit til en langstrakt sekskant. Papiret i sidevæggene for-25 hindrer endvidere en svejsning langs siderandene til lukning af posen, hvorfor sådanne poser hidtil ikke er blevet forsynet med et aromatæt lukke, men kun på klappen har en almindelig klæbestrimmel, der holder klappen ned over åbningen for at forhindre, at tobakken direkte falder ud af posen. Dette 30' har medført, at man til denne form af tobaksposer hidtil kun har benyttet polyethylenfolier og ikke tænkt på yderligere at forbedre emballagens barriereegenskaber. Da tobakken således ikke er særlig beskyttet„har i det mindste pakkens sideflader hyppigt været af klar plast, således at tobakken yder-35 ligere kunne forringes ved lyspåvirkning, når det indlagte papir blev forskubbet.Such tobacco pouches are generally known in that the intermediate layer is usually of paper and optionally has transverse groove lines to form the inwardly facing bottom rim. Furthermore, the intermediate layer has a width such that it can be folded down along the sides of the full-sized box-shaped tobacco pouch, whereby the intermediate layer already has two longitudinal groove or perforation lines for folding the paper layer at the longitudinal edge of the tobacco pouch to form the side surfaces, so that these shaped side tabs from each side reach down to about the center of the side faces. In addition, in each interlayer 15 sheet blank bottom triangles must be punched to allow folding at the bottom of the purse. These lines and punches cause the interlayer sheets to be manufactured in a separate process and individually inserted between the outer and inner plastic folding layers fed from the roll. It has been found that such a tobacco purse is difficult to raise for filling of the tobacco friction, since the gripping fingers calculated on the feeding machine for this purpose do not always form the tobacco purse properly, since the side tabs will tend to break out and reshape the bag as seen in section. to an elongated hexagon. The paper in the side walls also prevents welding along the side edges to close the bag, so such bags have not hitherto been provided with an aromatic seal, but only on the flap has a regular adhesive strip which holds the flap down over the opening to prevent the tobacco directly falls out of the bag. This 30 'has meant that so far this kind of tobacco bags has only used polyethylene foils and no thought of further improving the barrier properties of the packaging. Thus, since the tobacco is not particularly protected, at least the side surfaces of the package have frequently been made of clear plastic, so that the tobacco could be further deteriorated by light exposure when the paper loaded was moved.

Det er den foreliggende opfindelses formål at anvise en i fyldt tilstand i det væsentlige kasseformet tobakspung, der er enklere og dermed billigere at fremstille på eksisterende produktionsmaskiner og som giver en sikrere kørsel i pakke-5 maskinen, lettere formes af tobakken, og som giver mulighed for en praktisk taget vanddamp- og aromatæt lukning af pungens posedel.SUMMARY OF THE INVENTION It is an object of the present invention to provide a substantially filled box-shaped tobacco purse which is simpler and thus cheaper to manufacture on existing production machines and which provides a safer operation in the packing machine, is more easily shaped by the tobacco, and which allows for a practically water vapor and aromatic sealing of the purse bag part.
Dette tilgodeses ved, at den indledningsvis omtalte tobaks-10 pung er ejendommelig ved det i den kendetegnende del af krav 1 anførte. Denne konstruktion af pungen gør det muligt, at også mellemlaget kan fødes direkte fra rullen, idet de enkelte ark på kendt måde afskæres under fremføringen forud for indføringen mellem plastbanen, der giver det ydre og det indre 15 plastfolielag. Ved at mellemlaget ikke går helt ud til svejse sømmen, men har en bredde, der nøjagtigt svarer til posedelens i fyldt tilstand største bredde og fastholdes i forhold til plastlagene, sikrer man, at mellemlagets kanter virker som skarpe foldekanter for den kasseformede posedels siderande 20 eller -vægge, hvilket medfører, at posen passerer lettere i pakkemaskinen og bedre formes i denne, idet den med større sikkerhed bliver stående i kasseform. Da der ikke er papir i posedelens sidevægge, opnår man endvidere, at disse oven over den i posen fyldte tobak på enkel måde kan formes til 25 ind mod lukkeklappens midte vendende false, hvis flader om ønsket kan fastgøres indbyrdes til lukning af siderandene samtidigt med, at den kasseformede posedels åbning lukkes tættere end hidtil muligt. Samtidigt får man den enklest mulige udførelsesform med sikkerhed for praktisk taget aroma- og 30 damptæt lukning af posedelen med mulighed for at få en lille gribefold, som brugeren kan trække i ved åbning af posedelen.This is contemplated by the fact that the tobacco purse mentioned above is peculiar to that of the characterizing part of claim 1. This design of the scrotum also allows the intermediate layer to be fed directly from the roll, the individual sheets being cut off in the known manner during feeding prior to the insertion between the plastic web providing the outer and inner plastic foil layers. Because the intermediate layer does not extend all the way to the weld seam, but has a width that exactly corresponds to the full width of the bag part and is held in relation to the plastic layers, it is ensured that the edges of the intermediate layer act as sharp fold edges for the side edges 20 of the box-shaped bag part or walls, which means that the bag passes more easily in the packaging machine and is better shaped in it, leaving it with greater security in box form. Furthermore, since there is no paper in the side walls of the bag part, it is obtained that these can be easily formed above the tobacco filled in the bag to 25 against the middle of the closure flap, the surfaces of which can, if desired, be fixed together to close the side edges simultaneously, that the opening of the box-shaped bag part is closed closer than previously possible. At the same time, one obtains the simplest possible embodiment with the certainty of practically aroma- and vapor-tight closure of the bag part with the possibility of obtaining a small gripping fold which the user can pull in when opening the bag part.
Ordet kasseform, som benyttet her, dækker, at posedelen, når den er fyldt, får en form svarende til et i det væsentlige 35 retvinklet parallelepipedum. Ved en praktisk taget aromatæt eller en vanddamptæt pakning forstås her en pakning, hvor lukningen i alt væsentligt er fuldstændig tæt og i det væsentlige svarer til permeabi1 i teten af det valgte plastmateriale.The word box shape, as used herein, covers that the bag portion, when filled, is given a shape corresponding to a substantially right angled parallelepipedum. By a practically aromatic seal or a water vapor-tight seal is meant here a seal in which the closure is substantially completely dense and substantially corresponds to the permeability of the selected plastic material.

Det i den kendetegnende del af krav 2 anførte medfører en lettere bukning og lukning af posedelens åbning efter, at der er fyldt tobak i posedelen.The characterizing part of claim 2 results in a slight bending and closing of the opening of the bag part after tobacco is filled in the bag part.
5 Opfindelsen angår også en fremgangsmåde til fremstilling af tobakspungen ifølge opfindelsen og af den i krav 4 *s indledning angivne art. Ved at denne fremgangsmåde er ejendommelig ved det i den kendetegnende del af krav 4 anførte får man en enkel fremgangsmåde til fremstilling af en tobakspung 10 af den art, der har en indadvendende bundfals og en lukkeklap og i fyldt tilstand en i det væsentlige kasseformet posedel og som ifølge opfindelsen kan lukkes aromatæt og undgår ændring af tobakkens fugtighedsindhold.The invention also relates to a method of making the tobacco purse according to the invention and of the nature specified in the preamble of claim 4 *. This method is characterized by the characterizing part of claim 4, which provides a simple method for producing a tobacco purse 10 of the kind having an inwardly facing bottom flap and a closing flap and in a filled state a substantially box-shaped bag part and which according to the invention can be closed aromatically and avoids changing the moisture content of the tobacco.

For de viste udførelsesformer er der for identiske dele benyttet de samme henvisningstal.For the embodiments shown, the same reference numerals are used for identical parts.
4 umi I fig.l og 4 ses en tobakspung 1 ifølge opfindelsen som rejst for fyldning. Den har en i flad tilstand indadvendende bundfals 2 og en lukkeklap 3 samt en i rejst tilstand i det væsentlige kasseformet posedel 4. På lukkeklappens yderside er der 5 påklæbet en klæbestrimmel 5 til løsbar fastholdning af lukke klappen henover posedelen.Figures 1 and 4 show a tobacco purse 1 according to the invention as raised for filling. It has a flattened bottom flap 2 and a flap flap 3 as well as a substantially box-shaped bag portion 4. On the outside of the flap, an adhesive strip 5 is removable for releasably holding the flap over the bag portion.
Tobakspungen er fremstillet af et ydre plastlag 6 og et indre plastlag 7, der er udskåret af de i fig. 2 og 5 viste folie-agtige plastbaner 6', 7’. Mellem de to plastlag er der ind-*-0 skudt et mellemlag i form af papirark 8, 8", idet dog også andre materialer end papir kan tænkes anvendt. Samtidig med mellemlaget kan der lægges en afstivningsstrimmel 17, 17' imellem papirarket 8 og det ene af plastlagene 6, 7. Denne afstivningsstrimmel er dog ikke altid nødvendig. I et til-fælde (fig. 4) er afstivningsstrimlen 17' en papirstrimmel, der på den ene side er belagt med et svejsemedie, der binder over for papir og på den anden side belagt med et svejsemedie, der binder over for den benyttede plast. Ved indlægningen af afstivningsstrimmelen 17’ fastholder den papirarket 8 ved den ΟΛ ende, der skal danne en bagvæg 11rs endekant 16.The tobacco pouch is made of an outer plastic layer 6 and an inner plastic layer 7 cut out of the ones in FIG. 2 and 5, film-like plastic webs 6 ', 7'. Between the two plastic layers, an intermediate layer is shot in the form of paper sheets 8, 8 ", although materials other than paper can also be used. At the same time a stripping strip 17, 17 'can be inserted between the paper sheet 8 and one of the plastic layers 6, 7. However, this stiffening strip is not always necessary. In one case (Fig. 4), the stripping strip 17 'is a paper strip which is coated on one side with a welding medium which binds to paper and on the other hand, coated with a welding medium which binds to the plastic used.In the insertion of the stiffening strip 17 ', it retains the sheet of paper 8 at the ΟΛ end to form the end edge 16 of a back wall 11.
På indersiden af det ydre plastlag eller på ydersiden af papirarkene 8 er påtrykt en farvemærkning og tekst, idet det ydre plastlag i sidstnævnte tilfælde skal være transparent.On the inside of the outer plastic layer or on the outside of the sheets of paper 8 is a color marking and text, the outer plastic layer being transparent in the latter case.

De sammenlagte materialelag er foldet ind mod hinanden og svejset langs plastlagene 6, 7's siderande, hvorved der dannes svejsesømme 9, og hvorved pungens indadfalsede bund (ved 2), forvæg 10 og bagvæg 11 med en forlængelse til dannelse af låg-30 klappen formes. Hvis der benyttes en afstivningsstrimmel, perforeres (ved 22) pungen efter foldningen i afstivningsstrimmelens 17' bredde ved papirarkets kant, for derved at sikre korrekt ombukning i pakkemaskinen.The folded material layers are folded against each other and welded along the side edges of the plastic layers 6, 7 to form welded seams 9, thereby forming the inwardly folded bottom (at 2) of the purse, wall 10 and back wall 11 with an extension to form the lid flap. If a stiffening strip is used, the purse (at 22) is perforated after folding in the width of the stiffening strip 17 'at the edge of the paper sheet, thereby ensuring proper folding in the packaging machine.
35 Mellemlaget eller det indskudte papirark 8 har en bredde c svarende til bredden af den kasseformede posedel l's i fyldt tilstand største bredde B og er fastholdt således mellem plastlagene 6, 7, at dets sidekanter 12, 13 har i det væsentlige ens afstand fra plastbanernes sidekanter. Denne afstand svarer 4Q til den kasseformede posedels halve tykkelse 1/2 t plus bredden $ af siderandssvejsesømmene 9.The intermediate layer or inserted sheet of paper 8 has a width c corresponding to the width of the box-shaped bag portion 1's fullest width B and is held so between the plastic layers 6, 7 that its side edges 12, 13 are substantially equal to the side edges of the plastic webs. . This distance corresponds to 4Q of the half-thickness of the box-shaped bag part 1/2 t plus the width $ of the lateral weld seams 9.

Mellemlaget eller de enkelte papirark 8 er ved en eller begge af pungens tværgående endekanter 15, 16 fastholdt mellem det ydre 6 og det indre 7 plastlag, hvilken fastholdelse eventuelt kan ske ved svejsning eller limning. Mellemlaget kan fastgøres til det ene 5 plastlag 6 eller 7 via den samtidigt dertil svejsede afstivningsstrim mel 17', der samtidig svejses til papirarket. Benyttes den nedenfor omtalte afstivningsstrimmel 17 ikke, fastholde papirarket 8 direkte af de to plastlag 6, 7.The intermediate layer or individual sheets of paper 8 are held at one or both of the transverse end edges 15, 16 of the purse between the outer 6 and the inner 7 plastic layer, which may be held by welding or gluing. The intermediate layer can be attached to one of the plastic layers 6 or 7 via the simultaneously welded stiffening strip flour 17 ', which is simultaneously welded to the sheet of paper. If the stiffening strip 17 referred to below is not used, hold the paper sheet 8 directly by the two plastic layers 6, 7.
10 Alternativt kan der på det indre plastlag 7 som vist på den mod posedelens indre vendende side ved lukkeklappens endekant 16 fastgøres en i plastlagenes fulde bredde forløbende afstivningsstrimmel 17 af et egnet materiale. Den er fortrinsvis en papirstrimmel, hvis to sider er belagt med forskellige po-^5 lyolefiner, idet den mod det indre plastlag 7 vendende side fortrinsvis er belagt med en polyethylen med lille massefylde og er svejset til dette plastlag, medens den frie side er belagt med en polyethylen med stor massefylde„Alternatively, on the inner plastic layer 7, as shown on the inner side of the bag part, at the end edge 16 of the closure flap, a stiffening strip 17 extending in the full width of the plastic layers can be attached. Preferably, it is a paper strip whose two sides are coated with different polyolefins, the side facing the inner plastic layer 7 being preferably coated with a low density polyethylene and welded to this plastic layer while the free side is coated. with a high density polyethylene „
Ved endekanten 15 ved posedelens åbning 18 er der parallelt 20 .At the end edge 15 at the opening portion 18 of the bag portion, there is parallel 20.
med endekanten og lidt inden for eller over for denne og pa den indadvendende side påført et ved varme reaktiverbart bindemiddel i form en tværgående strimmel 19, 19'. I den på tegningen viste udførelsesform er denne strimmel påført på det indre plastlag 7, men den kan også være påført på det ydre plastlag 6, der 25 i så fald ombukkes, således at det får en indadvendende flig omfattende bindemiddelstrimmelen. Den sidstnævnte udførelsesform har den fordel, at der derved dannes en lidt stivere åbningskant ved endekanten 15, se også fig. 3 med tilhørende beskrivelse.with the end edge and slightly within or opposite this and on the inward-facing side, a transversely reactivable binder in the form is applied a transverse strip 19, 19 '. In the embodiment shown in the drawing, this strip is applied to the inner plastic layer 7, but it can also be applied to the outer plastic layer 6, which is then folded so as to obtain an inward-facing tab comprising the binder strip. The latter embodiment has the advantage of thereby forming a slightly stiffer opening edge at the end edge 15, see also fig. 3 with accompanying description.
Materialet for såvel det ydre 6 som det indre 7 plastlag er- fortrinsvis valgt blandt polyolefinerne og kan være baner 6',7' af enten polypropylen belagt med copolymer eller et laminat bestående af polyethylen og polypropylen belagt med en co-35 polymer eller kan være et laminat bestående af polyester og enten polyethylen eller polypropylen, fortrinsvis belagt med en copolymer.The material for both the outer 6 and the inner 7 plastic layer is preferably selected from the polyolefins and may be webs 6 ', 7' of either polypropylene coated with copolymer or a laminate consisting of polyethylene and polypropylene coated with a copolymer or may be a polyester laminate and either polyethylene or polypropylene, preferably coated with a copolymer.

Andre stoffer end papir kan vælges til mellemlaget. Under alle omstændigheder kan man metallisere inderlaget 7 på den fra posens indre vendende side.The intermediate layer is made of a paper web having a weight greater than 60 g / m2, preferably between 80 and 100 g / m2, but made of a paper web having a weight of approx. About 300 to about 2 to about 500 g / m, preferably about 400 g / m, in which latter case a semi-rigid carton is obtained, so that the finished tobacco pouch is box-like. Fabrics other than paper can be selected for the intermediate layer. In any case, the inner layer 7 can be metallized on the inner side of the bag.

Ved at vælge mellem de anførte plastmaterialer opnår man de billigst mulige materialer til fremstilling af netop denne tobakspung, hvilke materialer har den indbyggede nødvendige svejsbarhed, og at kunne regulere pungens gaspermeabilitet 15 ved hjælp af de kombinerede plastbaners barriereegenskaber, dvs. sikre pakningens aromatæthedsgrad og tæthed over for vanddamp. Disse barriereegenskaber bestemmes på grundlag af følgende enheder.By choosing between the listed plastic materials, you obtain the cheapest possible materials for producing this particular tobacco purse, which materials have the built-in weldability required, and being able to regulate the gas permeability of the purse 15 by the barrier properties of the combined plastic webs, ie. ensure the degree of saturation and density of the package against water vapor. These barrier properties are determined on the basis of the following units.
20 Vanddampstransmissionshastighed måles i g/m2/24 h ved 90% relativ fugtighed,38°C, 3 2 oxygenpermeabiliteten måles i cm /m /24 h/atm. ved prøvebetingelser med 0% relativ fugtighed, 23°C, 3 2 25 carbondioxidpermeabiliteten måles i cm /m /24 h/atm. ved prøvebetingelser med 0% fugtighed og 23°C.20 Water vapor transmission rate is measured in g / m2 / 24 h at 90% relative humidity, 38 ° C, 2 2 The oxygen permeability is measured in cm / m / 24 h / atm. for test conditions with 0% relative humidity, 23 ° C, carbon dioxide permeability is measured in cm / m / 24 h / atm. under test conditions with 0% humidity and 23 ° C.
Ved korrekt materialevalg kan man vælge disse barriereegenska-30 ber fra umålelig lav eller f.eks. med barriereegenskaber for . vand på 2,0 g/m2/24 h og op til 7,5 g/m2/24 h eller mere, en oxygenpermeabilitet på mellem 2 og 3400 cm3/m2/24 h/atm. og en carbondioxidpermeabilitet på mellem 6 og 10.000 cm /m /24 h/ atm.With proper material selection, these barrier properties can be selected from immeasurably low or e.g. with barrier properties for. water of 2.0 g / m2 / 24 h and up to 7.5 g / m2 / 24 h or more, an oxygen permeability of between 2 and 3400 cm 3 / m2 / 24 h / atm. and a carbon dioxide permeability of between 6 and 10,000 cm / m / 24 h / atm.

Herved gives der tobaksfabrikanten også for denne type af tobakspung for første gang mulighed for at vælge netop de barriereegenskaber, der passer bedst til den tobak, der skal fyldes i pungen og til at bestemme længden af den tid, hvor 5 tobakken skal holde sig aromafrisk og fugtig.This also allows the tobacco manufacturer for this type of tobacco purse, for the first time, to choose precisely the barrier properties that best suit the tobacco to be loaded into the scrotum and to determine the length of time for the tobacco to remain aromatic and damp.
Herved kan man på hensigtsmæssig måde styre posematerialets barriereegenskaber lige fra umålelig lav eller f.eks. med 2 barriereegenskaber for vand på lr0 g/m /24h og op til 7,5 2 10 g/m /24h eller mere, en oxygenpermeabilitet på mellem 2 og 3 2 3400 cm /m /24h/atmosfære og en carbondioxidpermeabilitet 3 2 mellem 6 og 10000 cm /m /24h/atmosfære, hvorved tobakspungen kan fremstilles i overensstemmelse med en tobak, der skal fyldes i pungen.In this way, one can conveniently control the barrier properties of the bag material from immeasurably low or e.g. with 2 barrier properties for water of lr0 g / m / 24h and up to 7.5 2 10 g / m / 24h or more, an oxygen permeability of between 2 and 3 2 3400 cm / m / 24h / atmosphere and a carbon dioxide permeability 3 2 between 6 and 10000 cm / m / 24h / atmosphere, whereby the tobacco purse can be prepared in accordance with a tobacco to be loaded into the purse.

Mellemlaget eller papirarket 8 er eventuelt fastholdt ved at svejse plastlagene 6, 7 sammen tæt ved en eller begge de tværgående endekanter 15, 16, så der dannes lommer, hvori mellemlagets endepart eller hjørner holdes fanget.The intermediate layer or sheet of paper 8 is optionally retained by welding the plastic layers 6, 7 together close to one or both of the transverse end edges 15, 16 to form pockets in which the end layer or corners of the intermediate layer are held captive.
20 Såfremt inderlaget ikke er metalliseret eller indfarvet foretrækkes det, at yderlaget 6 er gjort uigennemsigtigt langs po- -sedelens 4 sidevægge 21 for at hindre lyspåvirkning af tobakken.20 If the inner layer is not metallized or colored, it is preferable that the outer layer 6 is rendered opaque along the side walls 21 of the bag note 4 to prevent light exposure to the tobacco.
25 I fig. 3 ses et snit langs linien III-III i fig. 1 for den udførelsesform, hvor klæbemiddelstrimmelen 19'1 påføres på yderlaget 6, der er forlænget med en ombukket flig 20, der danner en lille gribevulst.In FIG. 3 shows a section along line III-III in FIG. 1 for the embodiment in which the adhesive strip 19'1 is applied to the outer layer 6 which is elongated with a folded tab 20 which forms a small gripping bead.
30 Det foretrækkes at benytte et ved varme genaktiverbart binde middel af den art, der ved afkøling til normal temperatur giver et let løsbart, tæt lukke. Dette bindemiddel vælges fortrinsvis blandt "hot melt" bindemidlerne og er fortrinsvis af den art, der består af en ethylenvinylacetatcopolymer, voks 35 8 1497 δ 1 og kunstharpikser. Det har fortrinsvis en valgt viskositet i området mellem ca. 1400 og ca. 3000 centipoise ved 150°C, fortrinsvis mellem ca. 1800 og 2300 centipoise. Bindemidlet påføres i en tykkelse på mellem 1 og 4 μ, fortrinsvis mellem 2 2 og 3 μ.It is preferred to use a heat-reactivable binding agent of the kind which, upon cooling to normal temperature, provides a readily detachable, tight closure. This binder is preferably selected from the "hot melt" binders and is preferably of the type consisting of an ethylene vinyl acetate copolymer, wax 35 8 1497 δ 1 and synthetic resins. It preferably has a selected viscosity in the range between about 1400 and approx. 3000 centipoise at 150 ° C, preferably between ca. 1800 and 2300 centipoise. The binder is applied at a thickness of between 1 and 4 µ, preferably between 2 and 3 µ.
Ét sådant bindemiddel har den egenskab, at det efter påføring og afkøling ikke har nogen tendens til at binde og sammenklæbe de under fremstilling, lagring og forsendelse mod hinanden ven-dende flader. Det kan ved hjælp af almindelig kendte fremgangsmåder genaktiveres hos tobaksfabrikanten efter posedelens fyldning med tobak. Det har endvidere den egenskab, at det kan aktiveres i hele temperaturområdet fra ca. 90° - ca. 150°C, således at der ved posens aromatætte lukning ikke som ved al-15 mindelig benyttede klatønidler skal gennemføres en nøjagtigere tempera turreguleret styring i emrådet mellem 130°C og· 140°C, hvilket er vanskeligt at gennemføre. Herved forenkles fremstillingen af tobakspungen yderligere.One such binder has the property that, after application and cooling, it has no tendency to bond and adhere to facing surfaces during manufacture, storage and shipment. It can be reactivated in the tobacco manufacturer by conventional methods after filling the bag portion with tobacco. It also has the feature that it can be activated in the entire temperature range from approx. 90 ° - approx. 150 ° C, so that with the aromatic sealed closure, as with commonly used climbing agents, a more precise temperature controlled control in the range between 130 ° C and · 140 ° C is not to be carried out, which is difficult to implement. This further simplifies the manufacture of the tobacco purse.
Det valgte bindemiddel har- en yderligere fordel. Såfremt det 2Q benyttes til at binde to ens materialer til hinanden, nemlig inderlag mod inderlag (fig. 1, 2 og 4) vil det give en svagere binding end hvis disse lag svejsedes direkte til hinanden. Såfremt det benyttes til at binde to forskellige materialer til hinanden, nemlig inderlag mod yderlag (fig. 3) vil det gi-25 ve en stærkere binding, end hvis man forsøgte at binde disse til hinanden alene ved varmepåvirkning (svejsning), hvilket endog i visse tilfælde er umuligt. Endvidere har det den fordel, at det nok giver en aromatæt lukning ved sammenbindingen af de to flader, men denne binding er dog ikke kraftigere end, 2q at en bruger nemt kan åbne posen uden at rive plastlagene i stykker, således som det nemt kan ske ved sammensvejsning af lagene. Efter genåbning af posen for brug er bindemidlet inaktivt, således at tobakken ikke vil klæbe dertil.The binder chosen has an additional advantage. If 2Q is used to bond two identical materials to each other, namely inner layer to inner layer (Figs. 1, 2 and 4), it will provide a weaker bond than if these layers were welded directly to each other. If it is used to bond two different materials to each other, namely inner layer against outer layer (Fig. 3), it will give a stronger bond than if one tried to bond these to each other only by heat effect (welding), which even in certain cases are impossible. Furthermore, it has the advantage of providing an aromatic sealing closure at the bonding of the two surfaces, but this bonding is no stronger than, 2q that a user can easily open the bag without tearing the plastic layers as easily as possible. by welding the layers. After reopening the bag for use, the binder is inactive so that the tobacco will not adhere to it.
35 Samtidig med denne sammenklæbning fastgøres de ved området ud for åbningen 18 i forbindelse med dennes lukning ved 21 dannede indadbukkede sidefalse til hinanden, således at praktisk taget fuldstæidig tætning opnås, netop fordi papirarket eller mellemlaget 8 ikke 9 140761 går helt ud til posedelens 4 sidesyejsesøm. Denne tætte lukning var på grund af de hidtil i posedelens sidevægge tilstedeværende papirlag ikke mulig, 5 Por at lette bukningen og lukningen af tobakspungen efter, at der er fyldt tobak i denne, kan yderlaget 6 og inderlaget 7 ifølge én udførelsesform i et område 9!, der i det væsentlige er begrænset af mellemlagets 8 langsgående kant, posedelens åbning 18, endekanten 16 af pungens bagvæg 11 og lage-10 nes 6, 7 langsgående fælles kant være svejset sammen i hele områdets 9' udstrækning jvf, det i fig. 6 viste.Herved dannes samtidigt en lomme, der fastholder mellemlaget, I stedet for kan man, som vist i fig. 7, have en ekstra svej-15 selinie 26, der strækker sig i det væsentlige fra posedelens åbning 18 til afstivningsstrimmelen 17, 17' og forløber tæt op ad mellemlagets 8 langsgående kant. En anden variation til at tilgodese den enkle bukning og lukning af tobakspungen er vist i fig. 8, hvor der er vist et lodret snit 23 anbragt tæt 20 uden for posedelens åbning 18 gennem svejselinien 9 og yder- og inderlagene 6, 7 ind til mellemlaget 8, hvilket snit er begrænset af svejselinier 24, 25. En variation af denne udførelsesform er vist i fig. 9, hvor det rektangulære område begrænset af svejselinien 9, mellemlaget 8, posedelens åb-25 ning 18 og endekanten 16 er udstanset, hvilket område er be grænset af svejselinier 28, 29 til sammenholdning af lagene 6, 7.35 At the same time as this adhesive, the inwardly bent lateral folds formed by the closure 18 of the opening 18 are secured to each other so that practically complete sealing is achieved precisely because the paper sheet or intermediate layer 8 does not extend all the way to the side side seam of the bag part 4. . Due to the paper layers present so far in the side walls of the bag part, this close closure was not possible. In order to facilitate the bending and closing of the tobacco pouch after the tobacco has been filled, the outer layer 6 and the inner layer 7 can according to one embodiment in an area 9! which is substantially restricted by the longitudinal edge of the intermediate layer 8, the opening portion 18 of the bag portion, the end edge 16 of the purse wall 11 and the longitudinal joint edge of the sheets 6, 7 being welded together throughout the extent of the area 9 ', cf. 6, while at the same time forming a pocket holding the intermediate layer. Instead, as shown in FIG. 7, have an additional weld 15 line 26 extending substantially from the opening portion 18 of the bag portion to the stiffening strip 17, 17 'and extending close to the longitudinal edge of the intermediate layer 8. Another variation to accommodate the simple bending and closing of the tobacco pouch is shown in FIG. 8, there is shown a vertical section 23 located tightly 20 outside the opening portion 18 of the bag part through the welding line 9 and the outer and inner layers 6, 7 into the intermediate layer 8, which section is limited by welding lines 24, 25. A variation of this embodiment is shown in FIG. 9, wherein the rectangular area is limited by the welding line 9, the intermediate layer 8, the opening portion of the bag part 18 and the end edge 16, which is bounded by welding lines 28, 29 for joining the layers 6, 7.
Tobakspungen fremstilles i den for øjeblikket foretrukne udfø-^ relsesform jvf. fig. 4 og 5 på følgende måde:The tobacco purse is manufactured in the presently preferred embodiment, cf. 4 and 5 as follows:
En indre 7' og en ydre 6' plastbane og et antal i forvejen for bundfalsning alene i tværretningen eventuelt rillede dobbelte papirarkemner 8' føres på i og for sig kendt måde frem over valser (ikke vist) for sammenlægning til dannelse af en lagdelt 35 149761 ίο konstruktion. Dette sker efter, at der enten på papirarkenes i færdig tilstand udadvendende eller på den ydre plastbanes indadvendende side er påtrykt den ønskede tekst og de ønskede farver. Ligeledes er der i forvejen på den ene bane 7' på den 5 flade, der vender bort fra mellemlaget i en afstand fra banens midterlinie svarende til afstanden fra endekanten 16 til posens åbningskant 18 påført en strimmel 19' af et, fortrinsvis ved varme genaktiverbart bindemiddel af den ovenfor airtalte art. Afstivningsstrimmelen 17' med dobbelt bredde, såfremt den benyttes, og de dobbelte 10 papirarkemner 8' er ligeledes i forvejen behandlet, så de kan svejses til hinanden, henholdsvis til plastbanerne 7', 6', og papirarkene er afskåret i længder til en bredde svarende til bredden af den kasseformede posedels i fyldt tilstand største bredde. De dobbelte ark styres fastholdt af afstivningsstrim-15 lerne 17' ind mellem plastbanerne således, at deres endekan ter er parallelle med plastbanernes sidekanter og således at de i plastbanernes fremførselsretning er anbragt med mellemrum. De således dannede dobbelte pungemner afskæres på i og for sig kendt måde (ikke vist) dels langs en linie parallelt 20 med fremføringsretningen og dels langs en linie vinkelret på fremføringsretningen på en sådan måde, at der langs hvert mellemlagsarks to længdesider er tilstrækkelig brede plastområder til at forme hver sin halvdel af hver sidevæg af posedelen plus éiaesvejsesømmen. Umiddelbart efter indstyringen 25 i valserne fastgøres eventuelt arkenes smalle endekanter til plastbanerne. Derpå renskæres posens indvendige kant og posen foldes. Efter foldningen perforeres plastlagene og afstivningsstrimmelen i dennes breddeog langs papirarkéts langsgående kant. Til slut sammensvejses siderandene til endelig form-30 ning af tobakspungen og klappen og alle yderkanter renskæres.An inner 7 'and an outer 6' plastic web and a plurality of pre-folding only in the transverse direction, possibly any grooved double paper sheets 8 'are advanced in rolls (per not known) for folding to form a layered sheet. ίο construction. This is done after the desired text and colors are printed either on the outward facing surface of the sheets of paper or on the inner side of the outer plastic web. Also, on one of the webs 7 'of the 5 surface facing away from the intermediate layer at a distance from the center line of the web corresponding to the distance from the end edge 16 to the opening edge 18 of the bag, a strip 19' of a, preferably heat-reactivable binder, is applied. of the kind mentioned above. The double-width stiffening strip 17 ', if used, and the double 10 paper sheets 8' are also pre-treated so that they can be welded to each other, respectively, to the plastic webs 7 ', 6', and the sheets of paper are lengthwise to a width corresponding to to the width of the box-shaped bag portion in full condition the greatest width. The double sheets are guided by the stiffening strips 17 'in between the plastic webs so that their end edges are parallel to the side edges of the plastic webs and so that they are spaced apart in the direction of the feed webs. The double wallet thus formed is cut in a manner known per se (not shown) partly along a line parallel to the feed direction and partly along a line perpendicular to the feed direction in such a way that sufficiently wide plastic areas for each interlayer sheet are provided for forming each half of each side wall of the bag part plus the weld seam. Immediately after the guide 25 in the rollers, the narrow end edges of the sheets are optionally attached to the plastic webs. Then, clean the inside edge of the bag and fold the bag. After the folding, the plastic layers and stiffening strip are perforated in its width and along the longitudinal edge of the paper sheet. Finally, the side edges are welded to finally form the tobacco pouch and flap and all outer edges are cleaned.
I stedet for et i forvejen behandlet papirark kan også ubehandlede papirark, der foroven fastgøres til afstivningsstrimmelen og/eller fastholdes af plastbanerne benyttes.Instead of a pre-treated sheet of paper, untreated sheets of paper which are attached to the stiffening strip and / or retained by the plastic webs can also be used.
35 En videre fordel ved den således fremstillede tobakspung er, at den lettere former sig om tobakken end en tilsvarende kendtA further advantage of the tobacco purse thus produced is that it more easily propagates the tobacco than a correspondingly known
