Nærværende oppfinnelse vedrører en beholder med lokk av den
type hvor en åpnet beholder på nytt er lukkingsbar ved at lokket er utført med en fastklemmingsanordning. Videre ér lokket anordnet slik at det sammen.med beholderen danner en
tettende lukking. Den tettende lukkingen erholdes ved at lokket er utformet med et ringformet kantparti for samvirk-ning med et ringformét flateparti hos beholderens åpnings-kant. Ved fylt originallukket beholder er lokket festet mot
åpningskantens ringformede flateparti, f.eks. ved sveising "éller liming. I beholderen er det anordnet en ringformet forsvakning, hvor forsvakningen befinner seg nærmere beholderens lengdeakse enn det partiet som er festet til lokket. Ved åpningen av beholderen brytes forbindelsen i den ringformede forsvakningen, slik at lokket og de ved lokket fastsittende ringformede flatepartier og eventuelt også den øverste delen av det tidligere beholderlegemet fraskilles fra selve beholderen.
Aktuelle anvendelsesområder for beholdere av denne type er begerformede eller eskeformede innpakninger for melk, smør, magarin og lignende varer. Slike beholdere kan ha varierende høyde og form og kan f.eks. være runde, rektangulære eller ovale. Det foreligger et meget sterkt ønske: om å kunne sikre at beholder av ovenfor angitte type etter at disse er fylt og igjenlukket ikke kan åpnes helt eller delvis av u-vedkommende uten at dette merkes av den endelige forbrukeren av pakningsinnholdet. Spesielt ved beholdere med tynne vegg-, er av termoplast foreligger det vanskeligheter med den nå kjente teknikk og sikre dette, da det i slike konstruksjoner ikke er mulig å anbringe sikker plombering.
Problemene er løst når det gjelder beholdere for engangsbruk ved at åpningen ved slike beholdere dekkes av et folieformet lokk av f.eks. plast eller av plast-metall-compoundfolie, som legges og forsegles mot åpningskanten. Ved åpningen av slike fylte original-igjenlukkede beholdere rives lokkfolien av, hvilket utelukker en ny anvendelse av lokket for igjenlukking av beholderen.
En igjenlukkingsbar beholder er kjent fra US patent 3 048 299, som omfatter et lokk som har en periferisk vulst som snepper inn bak en innvendig vulst ved beholderåpningen. For å av-stedkomme en originallukking kreves et ytterligere element i form av en plastfilm, som sveises fast ved lokket og ved en bortrivbar munningskant hos beholderen. Sneppertorganene fin-nes allerede der -fra begynnelsen og er nødvendige for såvel originallukkingen som en gjentatt igjenlukking. Den ekstra plastfilmen vanskeliggjør tillukningsoperasjonen og fordyrer forpakningen.
I US patent 3 108 708 beskrives en beholder av et plastmateria-le med et lokk av en plastfilm, som uten anvendelse av forbindel-sesmidler varmforsegles mot en ytre del av en utadstående munningsflens hos beholderen. Flensen er forsynt med et øvre spor og et nedre spor, hvilke spor sammen danner et oppriv-ningsområde for beholderen. Ved åpningen gjenstår den ytre flensdelen ved lokket og danner et ytre kantparti på dette. Noen sikker fastholdning av lokket ved en gjentatt lukking av beholderen erholdes ikke med denne kjente konstruksjonen.
Videre er det fra US patent 1 719 581 kjent en boks med et lokk som er festet ved bokslegemet ved hjelp av en dobbel-forsegling, og som har en indre sylindrisk side som er i friksjonsinngrep med innsiden til bokslegemet. Beholderlegemet er forsynt med en utvendig vulst, som delvis er anordnet for å gi stivhet til beholderlegemet slik at det bibeholder sin rette form, og delvis for å være i friksjonsinngrep med lokket ved friksjonsflater (se fig. 2) etter at en riveremse er fjernet fra beholderlegemet og lokket er presset ned ytterligere en bit. Riveremsen dannes av to snittlinjer mellom dobbelforseglingen og vulsten, og er forsynt med en tunge,
på hvilken man skal anbringe en spesiell nøkkel for å rulle opp riveremsen og dermed åpne beholderlegemet. Riveremsen blir således ikke noen del av lokket etter åpningen men må kastes bort.
Nærværende oppfinnelse vedrører nærmere bestemt en beholder med lokk som etter den første åpningen igjen kan tillukkes, hvor lokket ved originallukkingen er festet til beholderen langs en permanent forbindelse rundt munningsdelen, f.eks. ved sveising eller liming, slik at den første åpning foretas langs en ringformet opprivningsanvisning mellom selve beholderen og den permanente forbindelse, slik at lokket og den dertil permanent festede del av beholderen.skilles fra-... beholderen, og hvor lokket videre er utført med støtteflate for anlegg mot beholdermunningens innvendige vegg, for nøy-aktig plassering av lokk med permanent festet del ved gjentatt lukking av beholderen, og oppfinnelsen er karakterisert ved at den til lokket permanent festede del og lokkets støtteflate er slik innbyrdes plassert at beholderens munningskant vil bli fastklemt mellom disse ved gjentatt lukking.
Separate åpningsanvisninger i form av gripeorganer såsom tunge eller lignende kan ifølge oppfinnelsen anordnes enten i tilslutning til lokkets ringformede kantparti eller i til- . slutning til beholderens ringformede flensparti.
Oppfinnelsen skal i det følgende beskrives under henvisning til vedlagte tegninger, hvor: Fig. 1 a viser et'delsnitt gjennom en beholders åpningsdel og gjennom et ovenfor dennes beliggende lokk innen lokkets fastgjøring mot beholderen,
fig. 1 b viser et delsnitt av beholderens åpningsdel anordnet med to sveiseanordninger,
fig. 2 a-b viser delsnitt av en beholders åpningsdel med på
beholderen festet lokk,
fig. 3 viser et delsnitt av en beholders åpningsdel under åpningen av beholderen,
fig. 4 viser en delsnitt av en beholders åpningsdel ved
igjenlukket beholder,
fig. 5-7 viser utførelsesformen av beholdere og lokk anordnet ifølge de utførelsesalternativer som vises i fig. 1-4,
fig. 8-10 viser en prinsipiell anordning for fastgjøring av lokket mot beholderen ved hjelp av ultralydsveis-ing.
I figurene 1-6 gjenfinnes en beholder 10, som i sin munningsdel 11 overgår i en ringformet flens 13 med et flateparti 12. Det ringformede flatepartiet er utformet med en eller flere sveiseanvisninger 15. I overgangen mellom den ringformede flensen og beholderlegemet er det utvendig anordnet en ringformet forsvakning 16.
Videre gjenfinnes et lokk 30 som har et ringformet kantparti 31, som er tilpasset beholderens ringformede flateparti 12. Lokket har en sylindrisk del 33 som passer trangt mot inner-flaten hos beholderens munningsdel. I fig. 2b vises lokkets ringformede kantparti 31 forsynt med en nedadbøyd kant 50
for å gi øket stivhet til det ringformede kantpartiet. Her-ved erholdes en viss beskyttelse mot at forbindelsen i den ringformede forsvakningen brytes når krefter virker mot lokkets ringformede kantparti, f.eks. i forbindelse med trans-port eller stapling av beholdere.
I fig. 1 er lokket 30 beliggende ovenfor beholderen 10, mens
i fig. 2a og 2b er lokket påsatt beholderen, f.eks. ved hjelp av liming eller sveising. I fig. 3 er en kraft (se pil) an-brakt mot undersiden av beholderens ringformede flens 13, hvor-
ved den ringformede flensen fraskilles fra beholderlegemet i den ringformede forsvakningen 16. Ved fraskillingen danner det tidligere lokket sammen med den ringformede flensen 13
en enhet som ved ny igjenlukking av beholderen smetter inn i beholderens munningsdel på den måte som er vist i fig. 4.
I fig. 5 er det et gripeorgan 17 anordnet på den ringformede flensen 13, mens i fig. 7 er et gripeorgan 12 anordnet på lokket 30. I utførelsesformen ifølge fig. 7 kreves større styrke av forbindelsen mellom lokkets ringformede kantparti og beholderens ringformede flens enn i utførelsesformen iføl-ge fig. 5, da fastgjøringen skal motstå de dragkrefter som oppstår ved åpningen av beholderen.
Fig. 6 viser i perspektiv beholderens munningsdel 11 med et ovenfor beholderen beliggende lokk 30.
I figurene 8-10 vises en beholder 10, som med sin ringformede flens 13 hviler mot et mothold 40. Lokket 30 er plassert oven-på beholderen. Lokket hviler derved på den ringformede sveiseanvisningen 15 (se fig. 9). Ovenfor beholderen med lokk befinner det seg en ultralydsender eller sonotrod 41.
Ved fastgjøring av lokket mot beholderen presser sonotroden lokkets ringformede kantparti 31 mot sveiseanvisningen 15 hos beholderens ringformede flateparti 12. Ultralydsvingningene overføres via lokket til sveiseanvisningen, hvorved oppvarm-ing av materialet i området for sveiseanvisningen finner sted, slik at materialet i lokket forbindes med materialet i beholderen. Situasjonen etter sammensveisingen fremgår av fig. 10, hvor området for sammensveisingen er markert med henvisningstallet 34 (se også fig. 2-4).
