Description
Den foreliggende oppfinnelse- vedrører en avtettet-, tynnvegget beholder, omfattende et oventil åpent ytre hylster av-plastmateriale, og en indre foring- som- er innrettet til- å oppta beholderens innhold og som er fremstilt av plastmateriale' s'om: er- særlig ugjennomtrengelig for gass eller damp, samt et lokk som lukker- beholderens åpne ende og i området for beholderens øvre kant er gasstett forbundet- med foringen-. The present invention relates to a sealed, thin-walled container, comprising a top-open outer sleeve made of plastic material, and an inner liner which is designed to receive the contents of the container and which is made of plastic material such as: particularly impermeable to gas or steam, as well as a lid which closes the container's open end and in the area of the container's upper edge is gas-tightly connected to the liner.
I mange- tilfeller vil béholder-innhbldet i seg selv- ikke bevirke noen indre trykkoppbygriirig i beholderen', men- når be'h'oT-deren skal oppta en kullsyreholdig drikk vil det indre trykk i beholderen øke når temperaturen øker. Således blir beholdere for kullsyreholdigé drikkevarer, f. eks.- øl eller enkelte mineral-vann, lukket for å holde karbondioksydet i oppløsning i drikkevaren for å opprettholde kull syr énivået- i dr-ikkevaren inntil beholderen åpnes. In many cases, the container contents in themselves will not cause any internal pressure to build up in the container, but when the container is to absorb a carbonated drink, the internal pressure in the container will increase as the temperature increases. Thus, containers for carbonated beverages, e.g. beer or certain mineral waters, are closed to keep the carbon dioxide in solution in the beverage to maintain the level of carbon dioxide in the non-drinking product until the container is opened.
Enkelte kjente beholdere for kullsyreholdige drikkevarer består av et sylinderformet hylster av tynn metallplate med et metallokk påsatt. Disse beholdere lider imidlertid under de ulemper at de er tunge, kostbare og utsatt for korrosjon. Certain known containers for carbonated beverages consist of a cylindrical casing made of thin sheet metal with a metal lid attached. However, these containers suffer from the disadvantages of being heavy, expensive and prone to corrosion.
Det opprinnelige forslag som ga impuls til den foreliggende oppfinnelse gikk ut på å benytte en beholder av plastmateriale og å lukke denne med et metallokk, men det har vist seg at anvend-else av en beholder av et plastmateriale som er tilstrekkelig ugjennomtrengelig for gass til effektiv oppbevaring av innholdet i beholderen også er meget kostbar. The original proposal that gave impetus to the present invention was to use a container of plastic material and to close this with a metal lid, but it has been shown that the use of a container of a plastic material that is sufficiently impermeable to gas to effectively storage of the contents of the container is also very expensive.
Beholderen ifølge oppfinnelsen kjennetegnes ved at lokket The container according to the invention is characterized by the lid
er av metall pg er utstyrt med en flens, at det ytre hylster er utstyrt med en flens, at den indre foring er utstyrt med en flens som befinner seg over flensen på hylsteret, og at lokket er tett forbundet med beholderen ved at lokkflehsen, foringsflensen og det ytre hylsters flens er viklet til en spiral som er trykket is made of metal because it is equipped with a flange, that the outer sleeve is equipped with a flange, that the inner liner is equipped with a flange that is located above the flange on the sleeve, and that the lid is tightly connected to the container by the lid flange, the liner flange and the flange of the outer sleeve is wound into a spiral which is pressed
sammen i beholderens radialretning. together in the container's radial direction.
En utførelsesform av oppfinnelsen vil i det følgende bli beskrevet under henvisning til den medfølgende tegning, hvori: Fig. 1 viser et tverrsnitt gjennom en beholder ifølge oppfinnelsen, hvor det også er vist et omsluttende beger som benyttes sammen med beholderen til dannelse av en fullstendig emballasj e. Fig. 2, 3 og 4 viser vertikalsnitt gjennom beholderkanten i forstørret målestokk ved forskjellige faser av lukkingen av lokket til foringen. Fig. 5, 6 og 7 viser skjematisk hvordan beholderen lukkes An embodiment of the invention will be described in the following with reference to the accompanying drawing, in which: Fig. 1 shows a cross-section through a container according to the invention, where an enclosing cup is also shown which is used together with the container to form a complete packaging e. Figs 2, 3 and 4 show vertical sections through the edge of the container on an enlarged scale at different phases of the closing of the lid to the liner. Fig. 5, 6 and 7 show schematically how the container is closed
og bringes sammen med et omsluttende beger. and is brought together with an enclosing cup.
I fig. 1 er beholderen betegnet generelt med henvisnings-tall 10 og den, omfatter et ytre hylster 12 av slagfast polystyren, eventuelt et annet materiale, såsom A.B.S, eller poly-vinylklorid, og en indre foring 14 av et syntetisk plastmateriale som er meget, ugjennomtrengelig for gass under trykk, såsom "BAREX 210" eller et annet egnet materiale, og et metallokk 15 som lukker beholderen. In fig. 1, the container is denoted generally by the reference number 10 and it comprises an outer sleeve 12 of impact-resistant polystyrene, possibly another material, such as A.B.S, or polyvinyl chloride, and an inner lining 14 of a synthetic plastic material which is very, impermeable to gas under pressure, such as "BAREX 210" or another suitable material, and a metal lid 15 which closes the container.
Det ytre hylster 12 og den indre foring 14 kan vakuumformes samtidig av ett laminat av slagfast polystyren og "BAREX 210" idet det siste materiale anbringes på polystyrenet i ark- eller baneform eller påføres polystyrenet i væskeform. Det er mulig å utforme hylsteret og foringen hver for seg. The outer casing 12 and the inner lining 14 can be vacuum formed simultaneously from a laminate of impact-resistant polystyrene and "BAREX 210", the latter material being placed on the polystyrene in sheet or web form or applied to the polystyrene in liquid form. It is possible to design the casing and the lining separately.
Foringen 14 kan være en pose eller en sekk som fyller ut The lining 14 can be a bag or a sack that fills in
formen til hylsterets 12 indre flate ved fylling av dette. the shape of the inner surface of the casing 12 when filling it.
Når det ytre hylster og foringen formes sammen ved vakuum, som i det viste eksempel, har de samme form som har sirkelformet tverrsnitt og er sammensatt av en bunndel 16 som utgjør en del av et kuleskall, idet den f.eks. har halvkuleform, et kjeglestumpformet veggparti 18, et sylinderformet parti 20 som skal gripe inn med et omsluttende beger og en stablingsring 22. Ringen 22 har ved sin øverste ende en utadrettet flens forut for lukkingen av beholderen ved hjelp av lokket 15. Det kjeglestumpformete veggparti kan være fremstilt med spor som strekker seg aksialt eller langs omkretsen over en del av eller hele veggpartiet og som gir beholderen øket styrke og/eller øket evne til utvidelse. When the outer sleeve and the liner are formed together by vacuum, as in the example shown, they have the same shape which has a circular cross-section and is composed of a bottom part 16 which forms part of a ball shell, as it e.g. has a hemispherical shape, a frustoconical wall portion 18, a cylindrical portion 20 which is to engage with an enclosing cup and a stacking ring 22. At its upper end, the ring 22 has an outward facing flange before the closure of the container by means of the lid 15. The frustoconical wall portion can be produced with grooves that extend axially or along the circumference over part or the entire wall section and that give the container increased strength and/or increased ability to expand.
Lokket 15 kan f.eks. være fremstilt av aluminium og. ut-formet for åpning ved trekking i en ring, d<y>s. være forsynt med et lett fjernbart parti i den inntrukne hoveddel 24, som er festet til en ring som kan gripes med en finger slik at dette parti kan fjernes når beholderen skal åpnes-. The lid 15 can e.g. be made of aluminum and. out-shaped for opening when pulling in a ring, d<y>s. be provided with an easily removable part in the retracted main part 24, which is attached to a ring that can be grasped with a finger so that this part can be removed when the container is to be opened.
Lokket av metall har fortrinnsvis et beskyttende belegg, såsom en lakk eller en harpiks, som beskytter lokket mot behol-derinnholdet dersom metallet i lokket er utsatt for korrosjon. The metal lid preferably has a protective coating, such as a varnish or a resin, which protects the lid from the container contents if the metal in the lid is exposed to corrosion.
Det henvises så til fig. 2, 3 og 4 som illustrerer lukkingen av beholderen. Før lukkingen av den oppadvendte åpning har hylsteret 12 en utadrettet flens 26 og foringen 1-4 har en liknende utadrettet flens 28 som befinner seg over flensen 26. Lokket 15 har en oppragende vegg 3 0 hvorfra det rager ut en flens 32. Ved sin ytterkant har flensen 32 en nedad- og innad-rettet leppe 34. Lokket 15 har slike dimensjoner at når det føres ned over flensene 24 bg 22 vil leppen 34 innta den stil-ling som er vist i fig.. 2. Reference is then made to fig. 2, 3 and 4 illustrating the closure of the container. Before the closing of the upward-facing opening, the sleeve 12 has an outwardly directed flange 26 and the lining 1-4 has a similar outwardly directed flange 28 which is located above the flange 26. The lid 15 has a projecting wall 30 from which a flange 32 protrudes. At its outer edge the flange 32 has a downward and inwardly directed lip 34. The lid 15 has such dimensions that when it is brought down over the flanges 24 bg 22 the lip 34 will assume the position shown in fig. 2.
Flensene 3.2-, 28 -og 26 blir nå brettet innad slik som vist i fig. 3 ved hjelp av et egnet verktøy ved å dreie beholderen med lokket påsatt om dens akse og i forhold til verktøyet inntil flensene 26, 28 og 32 er bøyet spiralformet i:nn i hverandre slik at det oppstå-r tett lukking mellom lokket 15 bg hylsteret 12. I virkeligheten vil lokket 15 berøre foringen 1-4, og tet-ningen skjer derfor mellom lokket 15 "og foringen 14 . The flanges 3.2, 28 and 26 are now folded inwards as shown in fig. 3 by means of a suitable tool by rotating the container with the lid attached about its axis and in relation to the tool until the flanges 26, 28 and 32 are bent spirally into each other so that a tight seal occurs between the lid 15 and the casing 12. In reality, the lid 15 will touch the liner 1-4, and the seal therefore takes place between the lid 15 "and the liner 14.
For fullføring av påséttingen trykkes spiralen som dannes To complete the application, the spiral that is formed is pressed
■av flensene 32, -28 og 26 sammen radielt i forhold til beholder-aksen, -som antydet med piler X-X i fig. 4. ■of the flanges 32, -28 and 26 together radially in relation to the container axis, -as indicated by arrows X-X in fig. 4.
Det vil fremgå at det ikke finnes noen pakning eller noe tetningsmiddel på undersiden av lokkets 15 flens 3 2-, noe sbm •er vanlig praksis ved lukkingen av metallokk på metallbehol-dere. Det er en fordel ved denne oppfinnelse at denne pakning eller dette tetningsmiddel kan sløyfes, fordi flensen 3 2 og leppen 34 kan vikles lenger rundt i forhold til flensene 26 og 28 enn hva som ville være mulig dersom det ble benyttet en pakning eller tetningsmiddel. I enkelte tilfeller kan imidlertid et tetningsmiddel benyttes eller i andre tilfeller kan en defor-merbar pakning av plast benyttes. Denne kan være en termoplas-tisk eller en herdeplast som gjøres myk ved oppvarming for derved å bevirke lukking etter at flensene 24, 26 og 32 er brettet rundt hverandre. It will be seen that there is no gasket or sealant on the underside of the lid 15 flange 3 2-, which is common practice when closing metal lids on metal containers. It is an advantage of this invention that this gasket or this sealant can be looped, because the flange 3 2 and the lip 34 can be wound around longer in relation to the flanges 26 and 28 than would be possible if a gasket or sealant were used. In some cases, however, a sealant can be used or in other cases a deformable plastic seal can be used. This can be a thermoplastic or a thermosetting plastic which is softened by heating to thereby cause closure after the flanges 24, 26 and 32 have been folded around each other.
Beholderen fylles før den lukkes med lokket 15. The container is filled before it is closed with the lid 15.
Ved fyllingen av beholderne med kullsyreholdig drikkevare kan drikkevaren holdes på en temperatur under eller på omgiv-elsestemperatur. I begge tilfeller er det ønskelig å lukke beholderen så hurtig som mulig etter fylling for at innholdet av kull-syren eller karbondioksydet i drikkevaren ikke skal gå tapt. Resultatet er at etter at beholderen er fylt og lukket øker trykket i beholderen, og hylsterveggen 18 og bunndelen 16 ut-settes forxdette økte trykk. Bunndelen 16, som f.eks. er halv-kuleformet, er motstandsdyktig mot det indre trykk og deformeres ikke, men veggen er tilbøyelig til å utvide seg. Dette'motvirkes ved å plassere beholderen før, under eller umiddelbart etter fylling og påføring av lokk i et omsluttende beger 40 i fig. 1 som kan ha samme generelle form som beholderen, dvs. har en øverste kant 4 2 som ringen 2 2 hviler mot, en kjeglestumpformet vegg 4 4 med samme konisitet som veggen 18 og en stort sett plan bunn 4 6 som begeret kan hvile på når det bærer beholderen. Begeret 4 0 When filling the containers with carbonated beverage, the beverage can be kept at a temperature below or at ambient temperature. In both cases, it is desirable to close the container as soon as possible after filling so that the content of the carbon dioxide or carbon dioxide in the beverage is not lost. The result is that after the container has been filled and closed, the pressure in the container increases, and the casing wall 18 and the bottom part 16 are exposed to this increased pressure. The bottom part 16, which e.g. is hemispherical, is resistant to the internal pressure and does not deform, but the wall is prone to expansion. This is counteracted by placing the container before, during or immediately after filling and applying a lid in an enclosing cup 40 in fig. 1 which can have the same general shape as the container, i.e. has an upper edge 4 2 against which the ring 2 2 rests, a frustoconical wall 4 4 with the same conicity as the wall 18 and a largely flat bottom 4 6 on which the cup can rest when it carries the container. The cup 4 0
er fortrinnsvis av samme materiale som hylsteret 12, men dette er ikke nødvendig. is preferably of the same material as the casing 12, but this is not necessary.
Det antas at beholderen nettopp er blitt fylt med en kullsyreholdig drikkevare og lukket. Drikkevaren blir vanligvis ned-kjølt når den fylles på beholderen, men med økning i temperaturen vil trykket i beholderen stige og utvide veggen 18 slik at den trykkes fast mot veggen,44. Begeret 40 kan tjene som bærer for beholderen selv under fylling og lukking, fordi beholderen 10 som det fremgår har en avrundet bunndel slik at beholderen ikke kan stå oppreist ved egen hjelp. Beholderen med den av-rundete bunn kan imidlertid håndteres under fylling og lukking uten bruk av det omsluttende beger såfremt det benyttes egnete gripeorganer. It is assumed that the container has just been filled with a carbonated beverage and closed. The beverage is usually cooled when it is filled into the container, but with an increase in temperature the pressure in the container will rise and expand the wall 18 so that it is pressed firmly against the wall,44. The cup 40 can serve as a carrier for the container even during filling and closing, because the container 10, as can be seen, has a rounded bottom part so that the container cannot stand upright on its own. The container with the rounded bottom can, however, be handled during filling and closing without the use of the enclosing cup if suitable gripping means are used.
Når det benyttes et omsluttende beger 40 er begeret 40 When an enclosing cup 40 is used, the cup is 40
og hylsteret 12 fremstilt slik at det foreligger et svakt friksjonsinngrep mellom disse før veggen 18 utvides som et resultat av økningen av det indre trykk i beholderen. Dette oppnås ved at hylsterets sylinderformete parti 20 griper jevnt inn med den innvendige flate av ringen 4 2 på begeret 40. and the casing 12 produced so that there is a weak frictional engagement between these before the wall 18 expands as a result of the increase of the internal pressure in the container. This is achieved by the sleeve's cylindrical part 20 engaging evenly with the inner surface of the ring 4 2 on the cup 40.
Figurene 5, 6 og 7 illustrerer skjematisk de trinn som utføres for fremstilling av den ferdige pakning, idet fig. 7 omfatter beholderen og det omsluttende beger. I fig. 5 er beholderen 10 blitt fylt med en kullsyreholdig drikkevare og er i ferd med å bli påført lokket 15. Fig. 6 viser beholderen 10 etter at den er blitt lukket med lokket 15 og skal anbringes i begeret 40. Det første inngrep mellom begeret 40 og beholderen 10 er det svake friksjonsinngrep som ble nevnt ovenfor og som oppstår mellom ringen 20 og kanten 42, men dette friksjonsinngrep økes når veggen 18 utvides som et resultat av trykkstig-ningen i beholderen 10, noe som også er beskrevet ovenfor. Figures 5, 6 and 7 schematically illustrate the steps that are carried out for the production of the finished package, as fig. 7 comprises the container and the enclosing cup. In fig. 5, the container 10 has been filled with a carbonated beverage and is in the process of being put on the lid 15. Fig. 6 shows the container 10 after it has been closed with the lid 15 and is to be placed in the cup 40. The first engagement between the cup 40 and the container 10 is the weak frictional engagement that was mentioned above and which occurs between the ring 20 and the edge 42, but this frictional engagement is increased when the wall 18 expands as a result of the increase in pressure in the container 10, which is also described above.
