Description
146560
Opfindelsen angår en beholder med et låg, der efter at være åbnet første gang påny kan anbringes i lukkestilling og blive fastholdt med klemvirkning, og som forud for den første åbning er fastgjort på beholderen langs en permanent forbindelse omkring beholderens mundingsdel, f.eks. ved svejsning eller limning, og hvor der til frembringelse af den første åbning findes en ringformet oprivningsanvisning i beholdervæggen indenfor den permanente forbindelse i retning mod beholderens akse, således at en del af denne beholdervæg og låget med dets permanente forbindelse ved den første åbning kan adskilles fra det egentlige beholderlegeme på en sådan måde, at de dele af henholdsvis beholdervæggen og låget, der grænser op mod hinanden ved oprivningsan-visningen danner fastklemningsorganer, samt hvor låget er udformet med en støtteflade, som strækker sig ind i beholderen og sikrer lågets indføring i beholdermundingen i korrekt stilling til genlukning af beholderen.
Beholdere af denne type kan navnlig anvendes som bægerformede eller kasseformede emballager for mælk, smør, margarine og lignende varer. Disse beholdere kan have varierende højde og form og kan f.eks. være runde, rektangulære eller ovale. Til visse anvendelser findes beholdere med meget flad udformning såsom tallerkener eller skåle for tilberedte madvarer. I disse udførelsesformer har beholderne en meget stor åbning, der lukkes ved hjælp af et stort, plant låg. Der er et meget stort behov for at skaffe sikkerhed for, at beholdere af den foran anførte type, efter at de er fyldt og lukket, ikke kan åbnes helt eller delvis af uvedkommende, uden at dette kan ses af den endelige bruger af beholderens indhold. Navnlig ved tyndvæggede beholdere af termoplast er det med den hidtil kendte teknik vanskeligt at skaffe sikker-her for dette, idet det i sådanne beholdere ikke er muligt at anbringe en sikker plombering.
Problemet er ved beholdere til engangsbrug løst ved, at beholdernes åbning dækkes med et folieformet låg f.eks. af 146560 2 plast eller en folie af plast/metal-sammensætning, som anbringes mod og fastsvejses på kanten omkring beholderens åbning. Ved åbning af sådanne fyldte beholdere med originalt lukke rives lågfolien af, hvorved genanvendelse af låget til lukning af beholderen bliver udelukket.
Der kendes fra det britiske patentskrift nr. 906 180 en beholder af et plastmateriale med et låg i form af en plastfolie, der uden anvendelse af fastgørelsesorgan varme-forsegles til en ydre del af en udad ragende flange omkring beholderens munding. Denne flange er udformet med et øvre og et nedre spor, der sammen danner et oprivnings-område på beholderne. Når beholderen åbnes, bliver den ydre flangedel siddende fast på låget og danner et ydre kantparti på dette. Ved denne kendte konstruktion opnås ikke en sikker fastgørelse af låget ved genlukning af beholderen. Endvidere kendes fra USA patentskrift nr. 3 276 616 en beholder, der langs mundingskanten har en udvendig, nedad rettet krave, og hvor overgangen mellem mundingskanten og kraven er udformet som en svækkelse. Beholderen er lukket med et låg, der er fastgjort på kraven, der tjener som opbrydningsorgan til åbning af beholderen langs svækkelsen. Heller ikke ved denne konstruktion opnås en sikker fastgørelse af låget ved genlukning af beholderen.
Opfindelsen har til formål at anvise en beholder, der giver sikkerhed for, at det originale lukke ikke kan brydes, uden at dette kan iagttages, og som samtidig muliggør, at beholderen kan genlukkes effektivt ved hjælp af låget.
Dette er ifølge opfindelsen opnået ved, at beholderen med oprivningsanvisningen er således udformet, at når låget er i genlukket stilling, ligger den oprivningsflade, der dannes på låget ved opbrydning af oprivningsanvisningen, an mod det egentlige, adskilte beholderlegemes 3 146560 mundingskant, således at denne fastholdes mellem oprivnings-fladen og lågets støtteflade, i en stilling, der sikrer tætsluttende anlæg mellem det egentlige, adskilte beholderlegeme og låget.
Ved denne udformning af beholderen kan brugeren umiddelbart konstatere om emballagen allerede har været åbnet og der opnås samtidig mulighed for, at beholderen vil kunne genlukkes gentagne gange med sikker fastgørelse af låget.
En særlig effektiv fastgørelse af låget ved genlukning kan i-følge opfindelsen opnås ved, at lågets støtteflade består af en cylindrisk, ind i beholderen ragende del af låget, og den hermed samvirkende støtteflade på beholderen af den øvre indvendige kant af den fra det egentlige beholderlegeme adskilte mundingsdel. Herved lettes tillige lågets genanbringelse på beholderen.
Beholderen ifølge opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor fig. la i snit viser en del af en beholders munding og et over denne anbragt låg forud for lågets fastgørelse på beholderen, fig. Ib viser en del af en tilsvarende beholders munding udstyret med to svejseanvisninger, fig. 2 a-b i snit viser en del af beholderens munding med et derpå fastgjort låg, fig. 3 viser i snit en del af beholderens munding under åbning af låget, fig. 4 i snit viser en del af beholderens munding med genlukket låg, fig. 5-7 viser udførelsesformer for beholdere og låg ind- 146560 4 rettet ifølge de udførelsesalternativer, der er vist i fig.
1-4, og fig. 8-10 viser i snit en del af et apparat til fastgørelse af låget på beholderen ifølge opfindelsen ved ultralydsvejsning.
I fig. 1-6 er vist en beholder 10, hvis mundingsdel 11 går over i en ringformet flange med en ringformet anlægsflade 12, der er udstyret med en eller flere svejseanvisninger 15. I overgangen mellem den ringformede flange og beholderens væg findes en udvendig ringformet svækkelse 16. Endvidere findes et låg 30 med et udvendig ringformet kantparti 31, der modsvarer beholderens ringformede anlægsflade 12. Låget har en cylindrisk del 33, der passer tæt mod indersiden af beholderens mundingsdel. I fig. 2b er lågets ringformede kantparti 31 vist udformet med en nedad bøjet kant 50, der øger kantpartiets stivhed, hvorved der opnås en vis sikkerhed mod, at forbindelsen i den ringformede svækkelse brydes, når kræfter udøves mod lågets ringformede kantparti, f.eks. i forbindelse med transport eller stabling af beholderne.
I fig. 1 er låget 30 vist anbragt over beholderen 10, mens det i fig. 2a og b er vist fastgjort på beholderen f.eks. ved limning eller svejsning. Ifølge fig. 3 er en kraft rettet mod undersiden af beholderens ringformede flange 13, hvorved denne bliver adskilt fra beholderen i den ringformede svækkelse 16. Ved adskillelsen danner det tidligere låg sammen med den ringformede flange 13 en sammenhængende enhed, som ved genlukning af beholderen føres med klemvirkning ind i beholderens mundingsdel på den i fig. 4 viste måde.
Ifølge fig. 5 findes der et fingergreb 17 på den ringformede flange 13, mens der ifølge fig. 7 findes et fingergreb 32 på låget 30. I udførelsesformen ifølge fig. 7 kræves større 5 146560 styrke i den indbyrdes fastgørelse af lågets ringformede kantparti og beholderens ringformede flange end i udførelsesformen ifølge fig. 5, idet fastgørelsen skal modstå de trækkræfter, der opstår ved åbningen af beholderen.
Pig. 6 viser i perspektiv beholderens mundingsdel 11 og et over denne anbragt låg 30.
Fig. 8-10 viser en beholder 10, hvis ringformede flange 13 hviler på et modhold 40. Ovenpå beholderen er låget 30 anbragt således, at det hviler på den ringformede svejseanvisning 15 (jfr. fig. 9), og over beholderen og låget befinder sig en ultralydsender eller sonotrode 41. Ved fastgørelsen af låget på beholderen presser sonotroden lågets ringformede kantparti 31 mod svejseanvisningen 15 på beholderens ringformede anlægsflade 12, og ultralydsvingningerne overføres via låget til svejseanvisningen, hvorved materialet i svejseanvisningens område opvarmes, således at materialet i låget forbindes med materialet i beholderen. Situationen efter sammensvejsningen fremgår af fig. 10, hvor svejsningen er vist med 34, (jfr. også fig. 2-4).
