Description
7901315-7 Vid folierna enligt uppfinningen är väggarna hos utstans- ningarna eller utvikningarna utformade rätvinkligt till grund- ytan för folien och det inre tvärsnittet för dessa utstans- ningar är jämntöver deras djup och motsvarar tvärsnittet för öppningarna vid slutet av utstansningarna. Formen för utstans- ningarna och öppningarna kan vara valfri och exempelvis vara rund, rätvinklig, månghörning eller stjärnformig. Den minsta dimensionen för det inre tvärsnittet beror på de fordringar som ställes på folien. Minsta dimensioner upp -till 0,1 mm är möjliga. Vid mânghörniga eller stjärnformiga tvärsnitt hos utstansningarna är detta minsta mått diameternißr en i ut- stansningarna tänkbar innercirkel. Djupet för utstansningarna uppgår till minst 0,3 mm och kan även utgöra 0,5 till ungefär l mm. Det är likaledes beroende av fordringarna på folien. In the foils according to the invention, the walls of the punchings or folds are formed at right angles to the base surface of the foil and the inner cross-section of these punchings is equal to their depth and corresponds to the cross-section of the openings at the end of the punchings. The shape of the punches and openings can be optional and can be, for example, round, rectangular, polygonal or star-shaped. The smallest dimension of the inner cross-section depends on the requirements placed on the foil. Minimum dimensions up to 0.1 mm are possible. In the case of polygonal or star-shaped cross-sections of the punchings, this smallest dimension is a diameter smaller than an inner circle conceivable in the punchings. The depth of the punches amounts to at least 0.3 mm and can also be 0.5 to approximately 1 mm. It also depends on the claims on the foil.
I en föredragen utföringsform är tvärsnittet för utstansningar- na slitsformigt och har dimensioner av 0,2 x 6,0 mm, företrä- desvis 0,3 X 2,0 mm. Dessa slitsformiga utstansningar anord- nas företrädesvis i folien i rader förskjutna till varandra och har från rad till rad en växlande riktning gentemot fo~ liens centrumlinje. De är företrädesvis böjda omkring 450 gentemot foliens centrumlinje. I ytterligare utformning av denna folie är kanten hos öppningarna vid ändarna av utstans- ningarna förstyvade. Denna förstyvning sker genom en vulst.In a preferred embodiment, the cross section of the punches is slit-shaped and has dimensions of 0.2 x 6.0 mm, preferably 0.3 x 2.0 mm. These slit-shaped punches are preferably arranged in the foil in rows staggered to each other and have from row to row an alternating direction relative to the center line of the foil. They are preferably curved about 450 relative to the centerline of the film. In a further design of this foil, the edge of the openings at the ends of the punches is stiffened. This stiffening takes place through a bead.
Denna vulst ligger lämpligen utanpå vid sidoväggarna för ut- stansningarna varför tvärsnittet icke är reducerat.This bead is suitably located on the outside of the side walls of the punches, so the cross section is not reduced.
Den vätskegenomsläppliga folien är bildad av ett i oc h för sig ogenomsläppligt termoplastiskt material, såsom polyeten, polypropen, polyvinylklorid eller deras sampolymerer. Utgångs- folien har en tjocklek av från 0,02 till ungefär 0,06 mm. En- ligt ett föredraget förfarande, som icke utgör föremål för föreliggande ansökan, formas först i en präglingsspalt eller genom en vakuumbearbetning utstansningarna som vid sina ändar fortfarande är tillslutna. Genom en uppvärmning bringas änd- ytorna hos utstansningarna att krympa varvid öppningarna bil- das och vulsterna vid yttersidorna hos sidoväggarna av utstans- ningarna uppkommer.The liquid-permeable film is formed of a per se impermeable thermoplastic material, such as polyethylene, polypropylene, polyvinyl chloride or their copolymers. The starting foil has a thickness of from 0.02 to about 0.06 mm. According to a preferred method, which is not the subject of the present application, the punches which are still closed at their ends are first formed in an embossing gap or by means of a vacuum machining. By heating, the end surfaces of the punches are caused to shrink, whereby the openings are formed and the beads at the outer sides of the side walls of the punches arise.
Eftersom tvärsnitten för utstansningarna är lika i hela sitt djup besitter samtliga öppningar hos en folie samma inre tvär- 7901315-7 snitt även om genom mekaniska eller termiska inflytanden djupet för utstansningarna hos den färdiga folien skulle bli olika. Det konstanta tvärsnittet för utstansningarna ger dess- utom en optimal kapillärverkan. Genom en sammantryckning av den med ett absorberande inlägg försedda och genom folien en- ligt uppfinningen vid den sida från vilken vätskan skall in- tränga täckta artikeln kan mitt emot varandra liggande väggar hos utstansningarna sammantryckas så att härigenom en föränd- ring av det fria tvärsnittet uppkommer. Någon fullständig till- slutning kan dock icke inträda och åtminstone vid ändarna el- ler hörnen av utstansningarna förblir fortfarande genomgånge- öppningar fria även på grund av vulsterna.Since the cross-sections of the punches are the same in their entire depth, all the openings of a foil have the same internal cross-section, even if by mechanical or thermal influences the depth of the punchings of the finished foil would be different. The constant cross-section of the punches also provides an optimal capillary effect. By compressing the covered article provided with an absorbent insert and by the foil according to the invention at the side from which the liquid is to penetrate, opposite walls of the punches can be compressed so that a change of the free cross-section thereby occurs. . However, no complete closure can occur and at least at the ends or corners of the punches, passage openings still remain free even due to the beads.
En vittgående förslutning av öppningarna genom ett tryck på* materialet blir möjligt om djupet för utstansningarna är stör- re än deras minsta dimension. Vid en ungefärligen rätvinklig utformning och en motsvarande slits väljer man i detta fall djupet för utformningen större än dess bredd. För vissa fo- lier kan det dock även vara önskvärt att slitsen resp. öpp- ningen genom sammantryckningen icke förslutesför långt för att vid en minskning av den möjliga vätskegenomgângen man fortfarande skall erhålla en tillräcklig genomströmning av ångor, såsom exempelvis vid en andningsaktiv folie. Härvid ut- formar man slits och utstansning så att djupet för utstans- ningen exempelvis är mindre än hälften av dess minsta dimen- sion.A far-reaching closure of the openings by pressing the * material becomes possible if the depth of the punchings is greater than their smallest dimension. In the case of an approximately rectangular design and a corresponding slot, in this case the depth of the design is chosen greater than its width. For certain foils, however, it may also be desirable for the slot resp. the opening by the compression is not closed too far so that, in the event of a reduction in the possible liquid passage, a sufficient flow of vapors is still to be obtained, such as, for example, in the case of a breathable foil. In this case, the slit and punching are designed so that the depth of the punching, for example, is less than half of its smallest dimension.
Vulsterna förstärker kanterna för öppningarna och förhindrar därmed en sönderrivning av folien. Utstansningarna anordnas vanligtvis så att de intränger i det inre skiktet, som består av ett fiberformigt material. Eftersom vulsterna befinner sig utanpå vid änden av utstansningarna bidrar de till en förank- ring mellan täckfolien och inlägget så att folien icke utan vidare låter sig lyfta från inlägget och även en förskjutning av delar hos detta inlägg gentemot folien försvåras. Eventuel- la ojämnheter vid utbildningen av vulsterna kan vara av för- del för förbindningen med inlägget. 7901315-7 Folien kan vara försedd på sin hela yta eller också även en- dast i bestämda områden med utstansningar och öppningar.The beads reinforce the edges of the openings and thus prevent tearing of the foil. The punches are usually arranged so that they penetrate into the inner layer, which consists of a fibrous material. Since the beads are located on the outside at the end of the punches, they contribute to an anchoring between the cover foil and the insert so that the foil can not be easily lifted from the insert and also a displacement of parts of this insert towards the foil is made more difficult. Any irregularities in the formation of the beads can be of advantage for the connection with the insert. 7901315-7 The foil can be provided on its entire surface or even only in certain areas with punchings and openings.
Utföringsexempel av folien enligt uppfinningen åskådliggöres e sch matiskt i de bifcgade ritningarna i vilka Figur l och 2 visar snitt genom utstansningarna ; Figur 3 - 5 visar olika anordningar av utstansningar och öpp- ningar i iolien.Exemplary embodiments of the foil according to the invention are illustrated schematically in the accompanying drawings in which Figures 1 and 2 show sections through the punchings; Figure 3 - 5 shows different devices of punchings and openings in the oil.
Utstansningarna sker så att de inre ytorna hos sidoväggarna 2 hos utstansningarna formas ungefär i rät vinkel mot grundytan l hos folien. Avvikelser av upp till 50 från rät vinkel, såsom kan vara lämpligt för framställning och avtagning av folien vid en graverad metallcylinder, anses utan betydelse likaså små avrundningsradier mellan folien l och sidoväggarna 2. Si- doväggarna 2 hos utstansningarna har vid sina öppna ändar en vulst 3, som företrädesvis endast ligger på utsidan och icke begränsar tvärsnittet för kapilläret 4. När den minsta dimen- sionen för det inre tvärsnittet är tillräckligt stor kan vulsterna dock även skjuta in lite grann i kapillärerna såsom visas i fig. 2. 'gur 3 visar en folie ll med trekantiga utstansningar och 1 ppningar 12.The punchings take place so that the inner surfaces of the side walls 2 of the punchings are formed approximately at right angles to the base surface 1 of the foil. Deviations of up to 50 from the right angle, as may be suitable for the production and removal of the foil in an engraved metal cylinder, are considered insignificant as well as small rounding radii between the foil 1 and the side walls 2. The side walls 2 of the punches have a bead at their open ends 3, which preferably lies only on the outside and does not limit the cross-section of the capillary 4. However, when the smallest dimension of the inner cross-section is large enough, the beads can also protrude slightly into the capillaries as shown in Fig. 2. Figure 3 shows a foil ll with triangular punches and 1 openings 12.
Figur 4 visar en annan folie 13 med cirkelrunda utstansningar och öppningar 14.Figure 4 shows another foil 13 with circular punchings and openings 14.
Storleken, formen och djupet för utstansningarna och öpp- ningarne kan i varje situation anpassas till fordringarna.The size, shape and depth of the punchings and openings can be adapted to the requirements in each situation.
Det är dock fördelaktigt att mellan de enskilda utstansningar- na lämna en tillräckligt bred, jämn yta så att folien fortfa- rande besitter en tillräcklig hållfasthet och icke deformeras genom tanspänningen vid upplindning och vidare bearbetning.However, it is advantageous to leave a sufficiently wide, even surface between the individual punchings so that the foil still possesses a sufficient strength and is not deformed by the tensile stress during winding and further processing.
Figur 5 visar en íöredragen utföringsform av folien enligt uppfinningen vid vilken utstansningarna och öppningarna har 7901315-7 formen av rätvinkliga slitsar. Utstansningarna och äppningarnu 16 är placerade i folien lå i rader förskjutna till varandra och gentemot centrumlinjen omväxlande i dessa rader lutade företrädesvis omkring 450 mot motstående sidor.Figure 5 shows a preferred embodiment of the foil according to the invention in which the punches and the openings have the shape of rectangular slits. The punches and openings 16 are located in the foil lying in rows offset from each other and opposite the center line alternating in these rows preferably inclined about 450 towards opposite sides.
I denna föredragna utföringsform har utstansningarna och slit- sarna ett inre tvärsnitt av 0,3 x 2,0 mm. Avståndet mellan änden hos en slits och en angränsande slits uppgår vid denna utföringsform till ungefär 1,7 till 1,8 mm. De mellan slit- sarna återstående ytorna hos folien l5 kan vara präglade med en mycket fin pärlstruktur. Vid användning av denna folie i en tjocklek av ca 0,025 mm som täckfolie för ett absorberande in- lägg i en kombination, såsom den användes vid engångsblöjor, visade det sig att folien var behaglig för huden, att den snabbt kunde uppsuga vätska från huden och att även vid ett kraftigt genomfuktat inlägg och ett tryck på folien inträf- fade icke något tillbakaströmmande av vätskan. Vid normalt tryck på kombinationen inträffade icke någon märkbar deforma- tion av de slitsformiga utstansningarna och öppningarna.In this preferred embodiment, the punches and slits have an inner cross section of 0.3 x 2.0 mm. The distance between the end of a slot and an adjacent slot in this embodiment amounts to approximately 1.7 to 1.8 mm. The surfaces of the foil 15 remaining between the slits can be embossed with a very fine bead structure. When using this foil in a thickness of about 0.025 mm as a cover foil for an absorbent insert in a combination, as used in disposable diapers, it was found that the foil was comfortable for the skin, that it could quickly absorb liquid from the skin and that even with a heavily soaked insert and a pressure on the foil, no backflow of the liquid occurred. Under normal pressure on the combination, no appreciable deformation of the slit-shaped punches and openings occurred.
Först vid högre tryck och vid en böjning av folien ändrade sig dimensionerna i mitten av slitsarna medan vid deras ändar ka- pillärer av ungefär över deras längd lika tvärsnitt förblev bevarade. Vid kraftigt genomfuktade inlägg var denna tvär- snittsreduktion, som verkar ungefär som en läppventil, uppen- barligen gynnsam för att förhindra vätskan att rinna till- baka. -.._._........, ...._....-....-.,.-.-_~_.._--»--..._.._.._._Only at higher pressures and at a bending of the foil did the dimensions in the middle of the slits change, while at their ends capillaries of approximately equal length over their length remained preserved. With heavily soaked inserts, this cross-sectional reduction, which acts much like a lip valve, was obviously beneficial in preventing the fluid from flowing back. -.._._........, ...._....-....-.,.-.-_ ~ _.._-- »--... _.._.._._
