Foreliggende oppfinnelse angår nye utførel-sesformer for absorberende, puteformete kjerner The present invention relates to new embodiments for absorbent, pillow-shaped cores
av den art som brukes f. eks. i sanitetsbind, of the kind used, e.g. in sanitary napkins,
bleier, kompresser og liknende.nappies, compresses and the like.
De karakteristiske og nye egenskapene ved The characteristic and novel properties of
oppfinnelsen kan utnyttes i en rekke produkter the invention can be utilized in a number of products
for en-gangs-bruk, såsom sanitetsbind, bleier, for single use, such as sanitary napkins, nappies,
kompresser osv., når disse bl. a. består av en compresses etc., when these a. consists of a
absorberende puteformet kjerne, som innhylles absorbent cushion-shaped core, which is enveloped
i et hylster av en eller annen form, men i den in a holster of some form, but in it
følgende beskrivelse skal oppfinnelsen for en-kelthets skyld beskrives i forbindelse med kjerner for sanitetsbind. In the following description, for the sake of simplicity, the invention will be described in connection with cores for sanitary napkins.
Et sanitetsbind for en-gangs-bruk er prin-sipielt bygget opp av to elementer, nemlig en A sanitary napkin for single use is basically made up of two elements, namely a
absorberende kjerne som suger opp og holder på absorbent core that absorbs and holds
fuktigheten, og et hylster som holder kj ernen på the moisture, and a casing that holds the core
plass under bruk, og eventuelt hindrer at fuktigheten trenger ut av bindet, når den først er space during use, and possibly prevents the moisture from seeping out of the bandage, once it is
trengt inn.penetrated.
En bindkjerne er normalt ca. 15—20 cm lang, og 4—8 cm bred. Utskillelsen av menstruasjons-væske skjer imidlertid forholdsvis konsentrert. Behovet for absorpsjonsevne er derfor overlegent størst i bindets midtparti, da det er her det ve-sentligste av væskemengden, ikke bare må suges opp, men også oppbevares. For at kj ernens totale absorpsjonsevne skal kunne utnyttes best mulig, er det imidlertid viktig at den også er konstru-ert slik at fuktigheten spredes utover, og da for-trinnsvis i kjernens lengderetning, men også til en viss grad på tvers av kjernens lengderetning. A binding core is normally approx. 15-20 cm long, and 4-8 cm wide. The excretion of menstrual fluid is, however, relatively concentrated. The need for absorbency is therefore superiorly greatest in the middle part of the napkin, as this is where the bulk of the liquid must not only be absorbed, but also stored. In order for the core's total absorption capacity to be utilized as best as possible, it is, however, important that it is also constructed so that the moisture spreads outwards, and then preferably in the longitudinal direction of the core, but also to a certain extent across the longitudinal direction of the core.
Når man hittil på kjent måte har skullet bygge opp en kjerne med størst absorpsjons-evhe i kjernens midtparti, har dette medført at kjernen sett fra siden, har fått en tilnærmet ellipsoid form. Dette er av og til en fordel, av og til en ulempe. I et sanitetsbind vil det være en fordel under bruk, fordi en utflatet forpart på bindet vil være mindre synlig under stramtsit- tende klær, og en utflatet bakre del vil virke mer behagelig når bæreren sitter. Derimot vil den ellipsoide form være en ulempe når bindet skal bearbeides og håndteres i fabrikken, særlig i forbindelse med pakkemaskineriet, og vil også van-skeliggjøre en pent utseende pakning, dersom pakningsmaterialet er mykt, f. eks. av plast.. When, until now, it has been necessary to build up a core with the greatest absorption potential in the central part of the core, this has resulted in the core, viewed from the side, having an approximately ellipsoidal shape. This is sometimes an advantage, sometimes a disadvantage. In a sanitary napkin, there will be an advantage during use, because a flattened front part of the napkin will be less visible under tight-fitting clothes, and a flattened rear part will appear more comfortable when the wearer is sitting. On the other hand, the ellipsoidal shape will be a disadvantage when the bandage is to be processed and handled in the factory, especially in connection with the packaging machinery, and will also make a nice-looking package difficult, if the packaging material is soft, e.g. made of plastic..
Oppfinnelsen går ut på at man istedenfor den kjente fremgangsmåte, hvor-kjernen! bygges opp av flere lag, eventuelt av forskjellig størrelse osv., bygger opp en kjerne av defibrertj masse, slik at den har systematisk eller forutbestemt varierende massetetthet. j The invention involves that instead of the known method, where-the core! is built up by several layers, possibly of different sizes, etc., builds up a core of defibrated pulp, so that it has systematically or predetermined varying mass density. j
Den absorberende.puteformete kjernen iføl-ge oppfinnelsen karakteriseres nærmere bestemt ved at fibermaterialet er anordnet med (gradvis varierende materiallengde pr. volumenhet, således at et større antall fibre pr. volumenhet ut-gjør den del av kjernen hvor absorpsjonsbehovet er størst, mens materialmengden pr. volumenhet i kjernen er gradvis,.minskende i alle retninger bort fra denne del, og at kjernen har tilnærmet samme tykkelse over det hele. Innenfor rammen av den prinsipielle idé kan det utføres kjerner av meget varierende beskaffenhet, alt etter det behov som skal dekkes og de egenskaper man ønsker at kjernen skal jha. The absorbent, cushion-shaped core according to the invention is characterized in more detail by the fact that the fiber material is arranged with (gradually varying material length per unit volume, so that a larger number of fibers per unit volume constitutes the part of the core where the need for absorption is greatest, while the amount of material per . unit volume in the core is gradually decreasing in all directions away from this part, and that the core has approximately the same thickness throughout. Within the framework of the principle idea, cores of very varying nature can be made, depending on the need to be met and the properties you want the core to have.
I en bindkjerne vil prinsippet innebære at man gir massen størst tetthet i kjernens midtparti med en gradvis avtakende tetthet til begge sider utover i kjernens lengderetning, og eventuelt også i sideretningen, samtidig som bind-kjernens tverrsnittsareal i de fleste tilfeller kan opprettholdes tilnærmet konstant. Derved opp-nås at absorpsjonsevnen konsentreres der hvor behovet er størst, dvs. i midtpartiet, fordi dette partiet inneholder mest. masse. Men samtidig vil den avtakende massetetthet til begge sider i kjernens lengderetning bevirke at den oppsugde væskemengden raskere og mer effektivt jspredes utover fra kjernens sentrum, enn hva tilfelle vil være i en masse med konstant tetthet. Motstan-den mot væskegjennomtrengning og således kjernens evne til å fordele væsken vil øke når massetettheten minsker. Dette forhold utnyttes på effektiv måte gjennom oppfinnelsen,] slik at de vanlig kjente, særskilte fordelingslag eller -skikt i kjernen i sin helhet kan sløyfes. In a binder core, the principle will involve giving the mass the greatest density in the central part of the core with a gradually decreasing density to both sides outwards in the longitudinal direction of the core, and possibly also in the lateral direction, at the same time that the cross-sectional area of the binder core can in most cases be maintained approximately constant. This achieves that the absorption capacity is concentrated where the need is greatest, i.e. in the middle part, because this part contains the most. a lot. But at the same time, the decreasing mass density on both sides in the longitudinal direction of the core will cause the absorbed amount of liquid to spread outwards from the center of the core faster and more efficiently than would be the case in a mass with constant density. The resistance to liquid penetration and thus the core's ability to distribute the liquid will increase when the mass density decreases. This ratio is utilized in an efficient way through the invention,] so that the commonly known, special distribution layers or layers in the core can be omitted in their entirety.
Kjernen fremstilles ifølge oppfinnelsen hen-| siktsmessig på den måten at materiaiet] f. eks.j defibrert cellulose, tilvirkes i egnet maskineri som en kontinuerlig matte, som under produk-sjonsprosessen gir vekslende massetetthet i; lengderetningen, og eventuelt i sideretningen, i overensstemmelse med den ønskete lengden av den enkelte bindkjerne, samtidig som |matten gis jevn tykkelse og bredde, dvs. konstant tverrsnittsareal, hvoretter matten kuttes opp på tvers gjennom de partier som inneholder minst mate-riale, dvs. minst massetetthet. The core is produced according to the invention visually in the way that the material] e.g. defibrated cellulose, is produced in suitable machinery as a continuous mat, which during the production process gives alternating mass density i; in the longitudinal direction, and possibly in the lateral direction, in accordance with the desired length of the individual binding core, at the same time that the mat is given a uniform thickness and width, i.e. a constant cross-sectional area, after which the mat is cut up crosswise through the parts that contain the least material, i.e. .least mass density.
Oppfinnelsen skal i det følgende beskrives i detalj i forbindelse med vedlagte tegning, hvor: Figur 1 viser et lengdesnitt gjennom en kjerne av konvensjonell utførelse, In the following, the invention shall be described in detail in connection with the attached drawing, where: Figure 1 shows a longitudinal section through a core of conventional design,
figur 2 viser et lengdesnitt gjennom en ifølge oppfinnelsen utført bindkjerne, som ikke er pak-ket eller tatt i bruk, figure 2 shows a longitudinal section through a binding core made according to the invention, which has not been packed or put into use,
figur 3 viser bindkj ernen vist på figur 2, slik den ser ut når hylsteret er strammet. figure 3 shows the binding core shown in figure 2, as it appears when the sleeve is tightened.
Den konvensjonelle bindkj ernen 2, vist på figur 1, omfatter flere lag 4,4', osv. med avtakende lengde fra midten, slik at bindkj ernen i The conventional binder core 2, shown in Figure 1, comprises several layers 4, 4', etc. of decreasing length from the middle, so that the binder core in
lengdesnitt (og eventuelt i tverrsnitt) får tilnærmet ellipsoid form, som antydet med stiplete longitudinal section (and possibly in cross section) takes on an approximately ellipsoidal shape, as indicated by dotted lines
linjer 6. Mellom lagene kan anbringes ett eller lines 6. Between the layers can be placed one or
flere fordelingsskikt. På figuren er vist forde-lingsskiktet 8 i midten av kjernen. several distribution layers. The figure shows the distribution layer 8 in the middle of the core.
En bindkjerne ifølge oppfinnelsen vises i lengdesnitt på figur 2. Som det fremgår, er kjernens 10 massetetthet — som illustreres med tett-•hetsgraden av skraveringen^- varierende, og størst ved midten. Videre vil det bemerkes, at kjernen, sett i lengdesnitt, har rektangulær form. A binder core according to the invention is shown in longitudinal section in figure 2. As can be seen, the mass density of the core 10 — which is illustrated by the degree of density of the shading^ — is variable, and greatest at the center. Furthermore, it will be noted that the core, seen in longitudinal section, has a rectangular shape.
Graden av bibehold av den rektangulære tverrsnittsform, umiddelbart etter fremstillingen i maskineriet, vil være avhengig av flere fakto-rer, som elastisiteten i materialet (dys. elastisiteten i fibrene), massetettheten og materialets beskaffenhet for øvrig. Ved tilføring av bind-stoffer kan eksempelvis- tilbøyeligheten til eks-pansjon etter en sammenpresning reduseres eller elimineres. The degree of retention of the rectangular cross-sectional shape, immediately after production in the machinery, will depend on several factors, such as the elasticity of the material (dys. elasticity of the fibres), the mass density and the nature of the material in general. By adding binders, for example, the tendency to expansion after compression can be reduced or eliminated.
I de fleste tilfelle vil imidlertid kjernen etter fremstilling besitte mer eller mindre latente eks-pansjonskrefter som vil være proporsjonale med massetettheten, slik at kjernen om ønsket umiddelbart etter fremstillingen kan anta en form In most cases, however, after manufacture, the core will possess more or less latent expansion forces which will be proportional to the mass density, so that the core can, if desired, assume a shape immediately after manufacture
som kan sammenliknes med kjernen vist på which can be compared to the core shown on
figur 1, dog med bibehold av langt større massetetthet i midtpartiet, slik som illustrert på figur 2. figure 1, although retaining a far greater mass density in the middle part, as illustrated in figure 2.
Ved fremstilling av kjerner for sanitetsbind har det vist seg fordelaktig å fremstille kjernen slik at den stort sett bibeholder rektangelformen, When producing cores for sanitary napkins, it has proven advantageous to produce the core so that it mostly retains its rectangular shape,
sett i lengdetverrsnitt, bl. a. av hensyn til den seen in longitudinal cross-section, p. a. for the sake of it
videre behandlingen og pakkingen, og som bl. a. further processing and packaging, and such as a.
går ut på at kjernen forsynes med hylster eller means that the core is supplied with a sleeve or
liknende, og pakkes eksempelvis i en plastfolie, med den følge at bindkj ernens tilbøyelighet til å ekspandere hemmes. similar, and is packaged, for example, in a plastic film, with the result that the connective tissue's tendency to expand is inhibited.
Hårdheten eller sammentrykkbarheten av en kjerne ifølge oppfinnelsen vil naturligvis stort sett avhenge direkte av massetettheten. Når kjernen er anbrakt i et hylster, som utsettes for The hardness or compressibility of a core according to the invention will of course largely depend directly on the mass density. When the core is placed in a casing, which is exposed to
strekk, slik som tilfelle er når bindet tas i bruk, stretch, as is the case when the bandage is put into use,
vil særlig bindets endepartier utsettes for et re-lativt stort trykk eller press fra siden, slik som the end parts of the bandage in particular will be exposed to a relatively large pressure or pressure from the side, such as
det illustreres skjematisk på figur 3, hvor bok-stavet P betegner strekkraften eller strekkspen-ningen mens K betegner trykkraften fra det om-givende hylster, og som er rettet mot kjernens endepartier. Det er på det rene at også en it is illustrated schematically in figure 3, where the letter P denotes the tensile force or the tensile stress while K denotes the compressive force from the surrounding casing, and which is directed towards the end parts of the core. It is clear that also one
kjerne med konstant massetetthet vil presses sammen analogt med en kj erne ifølge oppfinnelsen, men sammenpresningsgraden vil ved en kjerne ifølge oppfinnelsen bli langt større, bl. a. core with constant mass density will be compressed analogously to a core according to the invention, but the degree of compression will be far greater with a core according to the invention, i.a. a.
fordi kraften K mot kjernens endepartier vil because the force K against the end parts of the core will
resultere i en ihnoverrettet kraftkomponent F, som direkte bidrar til at de latente ekspansjons-kreftene'i midtpartiet i noen grad frigjøres, slik at midtpartiet ekspanderer. Forsøk har vist at bindkj ernen ifølge oppfinnelsen — til tross for sammenpressingen som foran beskrevet — bibeholder langt større massetetthet i midtpartiet, result in an undirected force component F, which directly contributes to the latent expansion forces in the middle section being released to some extent, so that the middle section expands. Experiments have shown that the binder core according to the invention — despite the compression as described above — maintains a much greater mass density in the middle part,
slik at kjernen besitter såvel større absorpsjonsevne, som større fuktighetsfordelingsevne. so that the core has greater absorption capacity as well as greater moisture distribution capacity.
Ved at endepartiene av bindkj ernen presses By pressing the end parts of the ligament core

Ved å variere kjernens massetetthet, særlig By varying the mass density of the core, in particular
massetetthetsvariasjonen langs lengdetverrsnit-tet, har det vist seg mulig å fremstille bindkj er-ner med den absorpsjonsevne, ekspansjonsevne, mass density variation along the longitudinal cross-section, it has proven possible to produce binder cores with the absorption capacity, expansion capacity,
