Description
446 395 Uppfinningen kommer_i det följande att beskrivas med hänvisning till bifogade schematiska ritning, i vilken Fig. l visar en tubförpackning i enlighet med uppfinningen.
Fig. 2 visar ett tvärsnitt av en del av tuben från vilken förpackningen tillverkas.
Fig. 3 visar hur tuben formas på en dorn samt Fig. 4 och 5 visar hur en tublängd motsvarande tvâ tubförpackningar formas på en delbar dorn.
Vid tillverkning av tuben i enlighet med uppfinningen måste först ett lämpligt material framställas. Plastmaterialet från vilket tuben framställes kan i och för sig utgöras av ett laminat mellan olika plastmaterial, t ex polyeten, polypropen, polyester, etc. men ett mycket lämpligt material för! framställning av tubförpackning i enlighet med uppfinningen har visat sig vara den typ av akrylnitrilplast som marknadsföres under varumärket BAREX. Fördelen med detta material är att det är lätt att extrudera, att orientera samt mycket lätt att svetsa med hjälp av högfrekvensteknik. Vidare har akrylnitrilmaterialet (BAREX) mycket god gastäthet, speciellt för syrgas, och materialet är dessutom resistent för de flesta kemikalier och lösningsmedel. Tubförpackningen enligt uppfinningen är därför väl lämpad för förpackning av oxideringskänsliga produkter samt produkter av typen färger, -etc. I det föreliggande utföringsexemplet utgår vi således ifrån att plastmatêrialet utgöres av BAREX.
Materialet framställes på så sätt att en bred bana av materialet extruderas genom ett spaltformigt extrudermunstycke, varefter materialbanan utsättas för dragning i sin längsriktning, medan samtidigt den ursprungliga bredden på banan bibehålles eller ökas genom att den får passera ett flertal intill varandra belägna valsar, vilka förhindrar en s k "neck in effekt", d v s en hopsnörning aä banan då den utsättes för dragning. Orienteringen av banan ut- föres vid en temperatur hos plasten på c:a 70-900C och till- går så att banan får passera mellan par av samverkande valsar av vilk 446 395 S ett främre valspar har högre periferihastighet än ett bakre valspar, vilket i sin tur har en periferihastighet som i huvudsak motsvarar eller något överstiger extruderns utmatningshastighet. Genom att de nämnda valsparen har olika matningshastighet, kommer bandelen mellan valsparen att utsättas för sträckning som i sin tur medför en molekyl- orientering av materialet. De nämnda valsarna för att förhindra att banan krymper samman i tvärled då sträckningsoperationen befinner sig mellan främre och bakre valsparen medför i och för sig att banan även utsättes för mindre orienteringssträckning på tvären. En mera om- fattande tvärorientering kan erhållas om banans kanter samtidigt drages från varandra så att materialet sträckes i tvärriktningen.
Efter det att det orienterade materialet, vilket även ut- satts för en tjockleksreduktion, fått svalna kan det antingen rullas upp i en förrådsrulle eller direkt tryckas med valfri tryckmetod så att banan påföres önskad text och dekoration. Den sålunda tryckta banan kan därefter uppdelas i parallella delbanor som vardera inne- fattar en komplett dekorbredd. vardera av nämnda delbanor avskäres därefter till ark som formas till en tub genom att delbanornas kant- zoner förenas med varandra och sammansmâltes till en tät och hållbar överlappsskarv. var och en av de nämnda delbanorna är i huvudsak längsorienterat även om som nämnts ovan en viss tvärsorientering uppstår på grund av att banan under sträckningen kvarhâlles med konstant bredd. Eftersom vid inkrympningen av tubförpackningens domformade del 4 materialet måste ha en orientering i de bildade tubernas tvärsriktning framställes tuberna på så sätt att ett stycke av delbanornas främre parti,något överstigande omkretsen hos den färdiga tubförpackningen,avskäres. Den avskurna delen omvikes till en tub genom att delbanans främre kant och mittkanten hos den avskurna bandelen förenas med varandra i en överlappsskarv. Av detta följer att delbanornas bredd i huvudsak skall motsvara längden hos en tubförpackning (eller tvâ förpackningar om en samtidig framställninf av två tubförpackningsenheter sker enligt den nedan beskrivna metoden) Om BAREX-banan istället huvudsakligen molekylorienteras i sin tvärs- riktning, vilket kan ske genom en successiv isärdragning av Bankantern: i tvärsriktningen tills lämplig orienteringsgrad uppnåtts, kan iställei de bildade delbanorna formas till en kontinuerlig tub, vars längsaxel sammanfaller med delbanornas längsaxel, varefter den nämnda kon- tinuerliga tuben uppdelas i tubenheter vardera motsvarande en tub- förpackningsenhet, varefter de nämnda tubenheterna på beskrivet sätt utsattes för krympformning'pâ dorn samt fylles och förslutes. 446 395 I I och för sig kan förseglingen av överlappsskarven lätt innebära att materialetsorienteringsspänningar utlöses och mate- rialet krymper 1 längsskarven som deformeras. Detta kan 1 och för sig undvikas om materialet kan hållas sträckt under förseglingen men om detta skulle vara svårt, kan man istället för att direkt smälta samman de överlappande partierna i enlighet med fig. 2 extrudera en sträng smält BAREX-material 12 eller med BAREX kompatibelt plast- material på endera eller båda av de överlappande kantzonerna 10 och J vilka därefter sammanpressas. Fördelen med denna metod är att värmen från den extruderade plaststrängen 12 överföras till de överlappande kantzonernas 10 och ll ytskikt och förorsakar en ytlig samansmältnin med den pälagda strängen 12, medan däremot orienteringsspänningarna hos det orienterade BAREX-materialet inte utlöses och således krymp- ning 1 kantzonen undvikas. ¿ Den sålunda bildade längsskarvsförseglade tuben l kan antingen framställas 1 längder 8 motsvarande en tubförpaokningsenhet eller också 1 längreïlängder för att senare avskäras 1 längder 8 motsvarande en tubförpackningsenhet och i fig. 3 visas hur en tubläng 8 påföres en dorn 9, vilken dorn har en profilerad främre del 21 som 1 aet aktuella fenet fortsätter 1 ett eynnariext parti 13. efter det att tubdelen 8 uppträtt: på dornen tillföres värme företrädesvis 1 form av varmluft eller strälningsvärme till tubdelens främre parti 14, vilket inte har någon anliggning mot dornen 9. Genom uppvärmninge utlöses orienteringsspänningarna i materialet, varvid plastmaterialet bringas att krympa till noggrann anslutning mot dornens 9 profilerade del 21. Tubens 8 främre del 14 formas alltså pä sätt som illustreras med den streckade linjen i Eig. 3. Efter formningen kan dornen 9 dragas ur tuben 8. Tuben 8 har efter formningsoperationen erhållit en tömningsöppning som är väsentligen mindre än tubens genomskärnings yta och som framgår av det ovannämnda kan nämnda tömningsöppning omgivas av en utstående fläns om så önskas. Runt nämnda tömningsöpp- _ ning eller på nämnda fläns kan en prefabricerad, t.ex. sprutgjuten kapsylanordning som försetts med gånger och skruvlock lätt pâsvetsas p.g.a. att BAREX-materialet är lätt svetsbart med hjälp av hög- frekvens. Själva svetsningen kan tillgå så att den prefabricerade delen pressas till anliggning över den nämnda tömningsöppningen hos tuben med ett verktyg som samtidigt innehåller en högfrekvensspole.
Då ett elektriskt högfrekvensfält genereras kommer materialet att uppvärmas så att en sammansmältning mellan anliggande plastdelar ästadkomes. För att erhålla erforderligt mottryck kan det vara 446 395 lämpligt att svetsa på kapsylanordningen innan den inre dornen 9 avlägsnats från tuben.
En enklare öppnings- och tömningsanordning kan erhållas genom att den nämnda framskjutande flänsen 23 som visas i fig. 3 hoptryckes och hopförseglas med hjälp av värme för att sedan helt enkelt avskäras då tubförpackningen skall öppnas.
I enlighet med fig. 4 kan framställningssättet rationali- seras genom att samtidigt två stycken förpackningar hopkrympes i en arbetsoperation. Som framgår av fig. 4 utföres då dornen av två delar 16, 17, vilka delar kan separeras från varandra utmed skilje- linjen 18. Den samtidiga framställningen av två förpackningsenheter tillgår på så sätt att en längsskarvsförseglad tub 15 av orienterings sträckt plastfilm trädes upp på de sammanförda dornarna 16, 171. _ varefter den del 24 av tuben l5 som befinner sig i området för dornarnas profilering uppvärmes till krympning, varvid partiet 24 bringas till noggrann anslutning mot de samanförda dornarnas pro- filerade parti. Sedan plastmaterialet stabiliserats genom avsvalning, kan dornarna 16, 17 separeras från varandra genom axiella relativ- - rörelser, varefter den i fig. 5 visade, formade tuben 15 med sina inkrympta partier 18, 19 kan separeras utmed linjen 20 till erhålland av två stycken förpackningsenheter, vilka därefter på ovan nämnt sätt kan tillslutas eller förses med en kapsylanordning, fyllas samt ändförseglas.
Fördelen med metoden att samtidigt tillverka tva förpack- ningsenheter är att de bildade tömningsöppningarna som definieras av de öppningar som astadkommes då tuben 15 separeras utmed snitt-_ linjen 20 är att tömningsöppningen blir jämn och inte erfordrar någon efterbehandling eller "trimning“, vilket annars kan förekomma eftersom kantlinjen som definierar tömningsöppningen hos det in- krympta partiet ofta blir något ojämn efter krympningsförfarandet.
Vidare får tuben en väl definierad halslängd.
I fig. l visas en ”sprangd vy" av förpackningen enligt uppfinningen och som framgår av denna består tubförpackningen av en i huvudsak cirkulärcylindrisk tubkropp, vilken mot sin bakre del övergår till kilform för att avslutas i en rak tvärförsegling 3. e Vidare uppvisar tubförpackningen ett domformat eller kupat parti 4 som avslutas i en företrädesvis cirkulär tömningsöppning 5. Utöver hela tubkroppen 1 sträcker sig en längsförseglingsskarv 2, vars ändpunkter är lokaliserade till tvärförseglingsskarven 3 samt töm- ningsöppningens 5 kant. 446 395 Som ovan nämnts kan tubförpackningen tillslutas med hjälp av en förtillverkad kapsylanordning, vilken i enlighet med fig. l kan bestå av en sprutgjuten del § som uppvisar en rörformad tömnings- öppning, vars utsida förses med gängor. Kapsylen 6 är vidare försedd _med en likaledes sprutgjuten krage av plastmaterial samt en skruv- kapsyl 7 av konventionellt slag.
Den förtillverkade kapsylanordningen 6, 7 kan appliceras på tubförpackningen runt tömningsöppningen 5 ännu medan den krympta tuben 8, 15 är uppträdd på sin dorn 9. Företrädesvis är kapsyldelen 6 tillverkad av samma plastmaterial som tubkroppen, vilket bör vara -ett plastmaterial som kan förseglas med hjälp av högfrekvens, t.ex.
BAREX. Appliceringen av kapsyldelen 6 tillgå: så att den med ett särskilt verktyg som är kombinerat med en högfrekvensspole pressas mot omrâdet runt tömningsöppningen S med den inre dornen 9 som mothäll. Med hjälp av det högirekventa elektriska fältet uppvärmes plastmaterialet till“såväl kapsyldelens 6 krage som randzonen runt tömningsöppningen 5, varefter kapsyldelen 6 bringas att smälta samman med tubförpackningens främre del genom att den anpressas med stor kraft mot tubens inkrympta del 4.
Det har visat sig att tubförpackningar av här nämnt slag kan framställas betydligt rationellare och därmed billigare än konventionella tubförpackningar och eftersom de kan tillverkas med betydligt tunnare plastmaterial än konventionella tubförpackningar som är extruderade men inte orienteringssträokta blir även material- kostnaden låg. Dessutom kan tubförpackningarna användas för förpackni av fyllgods som ej får utsättas för syrgas eller som innehåller lös- ningsmedel eller andra agressiva kemikalier för vilka ordinära plast- material av typen polyeten, polypropen eller polyvinylklorid ej kan användas som förpackningsmaterial.
