Abstract
Lokkplate av sammensatt aluminium-plastfolie for fastklebing på plastflater. Plastsjiktet består av en EVA-PE-blanding, og platen er preget for å opprettholdes i planstilling. Det foretrekkes et lerretliknende pregningsmønster.
Description
Foreliggende oppfinnelse vedrører en dekkplate, bestående av aluminiumsfolie og minst ett plastsjikt, for fastklebing på kanten av en beholder som er fremstilt av plast eller belagt med et plastsjikt, hvor dekkplatens plastsjikt består av en blanding av minst én etylenvinylacetatkopolymer og én etylenpolymer.
Slike lokkplater har, særlig hvis plastsjiktet er ekstru-dert på aluminiumsfolien, den store ulempe at de vil sammen-rulles etter utstansingen, og dette er meget ugunstig for plat-enes viderebehandling. Utstansingen har av den grunn først kunnet foretas i forseglingsanordningen eller endog etter på-klebingen, da sammenrulling ikke lenger kan finne sted.
Oppfinnelsen har som formål å utforme lokkplater av oven-nevnte art på slik måte at sammenrullingsvirkningen ikke, eller bare i ubetydelig grad, vil opptre.
Dette er ifølge oppfinnelsen oppnådd ved at lokkplaten er preget i et linjemønster hvor pregelinjene danner en vinkel med hverandre og er forholdsvis lange, og hvor hver pregelinje fortrinnsvis strekker seg over hele platen.
Med en slik preging vil sammenrullingstendensen hos de utstansede plater reduseres i slik grad, at platene uten videre kan bearbeides. De kan eksempelvis fremføres som stabel til forseglingsanordningen, da de på grunn av pregningen vil lettere kunne fjernes fra stabelen.
Det har derved vist seg meget gunstig at pregelinjene, i overensstemmelse med oppfinnelsen, har en dybde av 40 - 150 |im og fortrinnsvis 90 |am.
Ifølge oppfinnelsen kan pregelinjene forløpe i en vilkår-lig, innbyrdes vinkel, men det har vist seg særlig gunstig at vinkelen mellom pregelinjene utgjør ca. 90°.
Det vil også være meget gunstig at pregelinjene, i overensstemmelse med oppfinnelsen, danner et tilnærmet lerrets-mønster.
Oppfinnelsen er nærmere beskrevet i det etterfølgende under henvisning til den medfølgende tegning, hvor:
Figur 1 viser et delsnitt av en lokkplate.
Figur 2 viser et planriss av en lokkplate med pregelinjer som danner en spiss, innbyrdes vinkel.. Figur 3 viser et planriss av en annen lokkplate med rett-
vinklet pregningsmønster.
Det er i figur 1 vist en aluminiumsfolie 1 som i en ekstruderingsprosess er belagt med et plastsjikt 2. Plastsjiktet 2 kan være tilvirket av en blanding av etylenvinylacetatkopolymer og etylenpolymer, som vil vise fremragende forseglingsegenskaper på de forskjelligste motmaterialer.
Dette forseglingssjikt fungerer særlig gunstig i forbindelse
med polystyrol, polypropylen, polyetylen og PVC som motsjikt. Med denne blanding har således forseglings/temperaturen kunne senkes til 130-180°, uten at forseglingssømmens styrke og sikre lukkefunksjon svekkes. Lokket lot seg dessuten lettere åpne uten innriss i materialet.
Etter beleggpåføringen ble aluminiumsfolien 1 forsynt med pregelinjer 3 med en dybde av ca. 90 nm. I fig. 1 er pregningen foretatt fra aluminiumsiden, men den kan også foretas fra plast-siden. Begge pregninger har den virkning at de utstansede lokkplater har ingen, eller bare ytterst liten, tendens til sammenrulling.
I fig. 2 er det vist en slik lokkplate 4 som er forsynt
med innbyrdes kryssende pregelinjer 3 og 30. Vinkelen mellom pregelinjene utgjør ca. 45°.
Figur 3 viser en lokkplate 40 med pregelinjer 3 og 50 som danner en rett vinkel med hverandre.
I begge utførelsesformer er lokkplaten forsynt med en av-rivningsflik henh. 6 og 7 som strekker seg langs halverings-linjen for vinkelen mellom pregelinjene, hvorved også avrivningen av lokkplaten lettes av pregelinjene.
Claims (4)
1. Lokkplate av aluminiumfolie og minst ett plastsjikt, for fastklebing på kanten av en beholder som består av plast eller er belagt med et plastsjikt, hvor lokkplatens plastsjikt består av en blanding av minst én etylenvinylacetatkopolymer og én etylenpolymer, karakterisert ved at lokkplaten (4,40) er preget i et linjemønster hvor pregelinjene (3,30,50) danner en innbyrdes vinkel og er relativt lange, og hvor hver pregelinje fortrinnsvis strekker seg over hele platen.
2. Lokkplate i samsvar med krav 1, karakterisert ved at pregelinjene (3,30,50) har en dybde av 40-150 um og fortrinnsvis 90 um.
3. Lokkplate i samsvar med krav 1 eller 2, karakterisert ved at vinkelen mellom pregelinjene (3,50) utgjør ca. 90°.
4. Lokkplate i samsvar med et av kravene 1-3, karakterisert ved at pregelinjene (3,50) danner et tilnærmet lerretsmønster.
