Abstract
Et sanitærbind med en absorberende vatt (14) som har blitt brettet om seg selv langs hver langsgående kant og deretter brettet innover for å tilveiebringe tre lag med absorberende vatt. Sanitærbindet har en fluidumgjennomtrengelig innpakning (10) som ligger over hver ytre (14a) og innvendige (14b) brett og ender ved de ytre kantene av det tredje laget (14c). Et fluidumtett dekke (22) er anbragt mellom de mange lagene av absorbsjonsmateriale og innpakningen (10), med unntak av den øvre delen som f.eks. vender mot kroppsflaten av. den absorberende vatten.
Description
Denne oppfinnelse angår et sanitærbind og spesielt et sanitærbind med en flerlag brettet absorberende komponent.
Nylig har man funnet ut at sanitærbind som inneholder absorberende lag med termoplastmateriale har visse fordeler i forhold til slike bind som kun anvender konvensjonelt cellulosemateriale som absorbsjonsmateriale. Tilstedeværelsen av termoplastmateriale gir det absorberende materiale elastisitet og medvirker også til å hindre sammenbrudd av kapillarrørene i cellulosematerialet når de to materialene blir blandet sammen. Eksempler på patenter som beskriver nyttiggjørelsen av termoplastmateriale i sammenheng med cellulosemateriale for sanitær-formål er:
De ovenfor nevnte patentene beskriver også idéen med sanitærbind med flere lag absorbsjonsmateriale.
Det har nylig blitt slått fast at sanitærbind med flere lag absorbsjonsmateriale, i hvilke lagene er dannet ved bretting, tilveiebringer øket komfort, ikke kun i de brettede områdene, men også med hensyn til motstand mot permanent forvrengning og elastisitet. Disse trekkene blir spesielt forsterket når termoplastfibre blir nyttiggjort gjennom hele den brettede absorberende vatten. Når termoplastfibre er tilstede blir motstanden mot permanent sammenpressing forsterket på grunn av tilstedeværelsen av hver individuell brett. Et bind med en absorberende vatt med termoplastfibre som har blitt brettet gjentatte ganger om seg selv skulle bli vesentlig mer komfortabel
enn et uten dette trekket.
I bind hvor termoplastfibre har blitt nyttigjort er det imidl-ertid generelt en reduksjon i totalabsorbsjonsevne og spesielt når fibre foreligger i store nok mengder som er tilstrekkelig til å gi elastisitet.
I henhold til denne oppfinnelsen er det tilveiebragt et sanitærbind, i hvilke en absorberende vatt er brettet innover langs hver langsgående kant og deretter igjen brettet for å tilveiebringe tre adskilte absorberende lag, en fluidumgjennomtrengelig innpakning som forløper over toppen av den absorberende vatten som danner det første laget og forløper over de brettede delene til de mange lagene som er dannet av den absorberende vatten. Bindet som er presisert ved denne oppfinnelsen benytter et fluidumtett dekke mellom den absorberende vatten og innpakningen i alle flater, med unntak av den delen av bindet som er ment å ligge inntil brukerens kropp.
Denne oppfinnelsen vil bli nærmere forklart med henvisning
til tegningene, i hvilke:
Fig. 1 viser et perspektiv, delvis i tverrsnitt, og fig. 2 viser et sidetverrsnitt langs linjen 2-2 i fig. 1.
Som vist i figurene er et sanitærbind forsynt med den første absorberende vatten 14 som har et øvre absorberende lag 14a,
et andre absorberende lag 14b som består av to like ben av materiale dannet av brettene 14a langs hver langsgående akse. Et tredje absorberende lag 14c har to adskilte ben som for-løper over de to benene som er dannet på laget 134b som et resultat av brettene vist ved 14b.
Den absorberende vatten 14 inneholder termoplastmateriale som gir elastisitet med ytterligere elastisitet som blir lagt til som et resultat av de mange lagene som er dannet av brettene 14a og 14b. Prosentinnholdet av termoplastmateriale kan bli variert mellom alt fra 10 til 100% i dette laget.
I denne bestemte utførelsesversjonen som er avbildet i fig. 1 og 2 er et mellomliggende absorberende lag 15 vist. Dette absorberende laget er utformet til å ha øket absorbsjonsevne sammenlignet med den absorberende vatten 14. På grunn av det spesielt høye nivået av innbygd elastisitetsmotstand i den absorberende vatten 14 er det ikke nødvendig å medregne elastisitet i noen stor utstrekning for dette mellomliggende laget 15. Laget 15 kan være et hvilket som helst av en rekke mat-erialer med god absorbsjonsevne, såsom konvensjonell tremassefluff eller et suberabsorberende materiale. Et spesielt fore trukket materiale er det som er beskrevet i US-patent 4.372.312 som er et overflateaktivt behandlet smelteblåst mikrofibervev. Dette spesielle vevet er kjennetegnet ved høy fluidumsugeevne og kan bli'- gnvendt1. f or;: seg- seiv reiler . i:.kombinas j on: med super-absorberende tremassefluff eller lignende.
Ved å vise til fig. 1 ligger innpakningen 10 over laget 14a
av vatten 14 og forløper rundt hver brett 14a og forløper ytterligere over den ytre, f.eks., bundelen av hvert ben som utgjør laget 14b, over hver brettede seksjon 14b og ender helt innerst i enden av laget 14c.
Det innvendige dekket 22 er anbragt mellom innpakningen 10 og det absorberende laget 14, med unntak av toppoverflaten av puten i et område som minst tilsvarer den flaten som ligger an mot brukerens kropp. Det innvendige eller det påfølgende dekket 22 definerer føringsganger for fluidumstrøm langs sidene av vatten 14 for å minimalisere lekkasje fra den vatten og er også medvirkende til å tilveiebringe omslutningsføringsganger for den mengden av fluidum som er tatt opp, men ikke blir holdt på av laget 15.
Dekket kan være av et hvilket som helst konvensjonelt termo plastmateriale som er kjent og dets bestemte sammensetning er ikke en del av denne oppfinnelse. Som vist i fig. 1 og 2 kan det omsluttende materialet 10 bli heftet til lagene 14 ved be liggenheter 11 ved sammensmeltingsultralyd-festing eller lignende for å forsterke fluidumledningsevnen gjennom det absorberende laget 14a.
Utførelsesversjonen avbildet i fig. 1 og 2 viser et ytterligere tilført andre dekke 16 som er tatt med for å øke bindets strukturstabilitet i en foretrukket utførelsesversjon av denne oppfinnelsen og, som kommer klarere frem i fig. 2, dekket 16 har tre striper med bindemiddel 17 festet dertil og et fri-gjøringsbelegg 18 for bindemiddelet. Bindet er tettet på
en konvensjonell måte ved hver ende, ved hjelp av ultralydinn-retninger, som vist som et klar flate på termoplastompak-ningsmaterialet 12 og dette etterlater frie ender 13.
Et bind laget i henhold til denne oppfinnelsen blir fortrinns-vis fremstilt ved å sonesamekstrudere termoplastdekket på
en ikke vevet innpakning. En slik prosess er f.eks. beskrevet i US-patent nr. 3.356.556 og er ikke en del av den patentsøkte oppfinnelse.
Dekket kan selvsagt bli skåret i strimler og ved hjelp av klebemiddel festes eller adskilt bli smeltet fast som altern-ative prosessfremgangsmåter. Belegget 14 blir så behørig anbragt på dekket og innpakningskombinasjonen og de to blir brettet to ganger langs hver kant av kombinasjonen for å danne strukturen som er fremstilt i denne oppfinnelsen. Hvis et ytterligere absorberende lag eller flere lag 15 skal anvendes blir de selvsagt anbragt under brettingstrinnet.
