Description
I de senere år har der skjedd store forandringer når In recent years, there have been major changes when
det gjelder måten ved åpning av blikkbeholdere. Mån har gjort bruk av fliker som rives ut ved hjelp av hemper. Disse fliker blir for det meste kastet på steder hvor folk ferdes og utgjør en del av forurensningen av omgivelsene. Det forekommer også at disse fliker ikke danner et tilfredsstillende lukke, fordi svekningslinjen rundt den blir presset inn for dypt. Hensikten med oppfinnelsen er å skaffe et lett-åpnelig lukke som ikke kan rives ut og kastes vekk, men som vil falle inn i beholderen eller eventuelt henge fast til lokkets innerside. it applies to the method of opening tin containers. Mån has made use of tabs that are torn out with the help of hempers. These flaps are mostly thrown in places where people travel and form part of the pollution of the surroundings. It also happens that these flaps do not form a satisfactory closure, because the line of weakness around it is pushed in too deeply. The purpose of the invention is to provide an easy-to-open closure which cannot be torn out and thrown away, but which will fall into the container or possibly stick to the inside of the lid.
Nærmere bestemt angår oppfinnelsen således et beholder- More specifically, the invention thus relates to a container
lokk med et manuelt inntrykkbar lukke som er begrenset av en i lokket dannet, ribbeformet forsenkning, i hvilken et sveknings-lin jeskår i lokkets underkant forløper således at det inntrykk- lid with a manually impressionable closure which is limited by a rib-shaped recess formed in the lid, in which a weakening line notch in the lower edge of the lid runs so that the impression
bare lukke er forbundet med beholderen over en bruddsøm, og det særegne ved oppfinnelsen er at svekningslinjens skår er preget inn i forsenkningens radialt nedadrettede sidevegg, og at svekningsskå- only close is connected to the container over a break seam, and the peculiarity of the invention is that the weakening line's cut is embossed into the radially downwards side wall of the recess, and that the weakening cut-
rets pregekanter som forløper til bruddsømmen, i det minste delvis berører hinannen. the embossing edges of the right leading to the break seam, at least partially touch each other.
Oppfinnelsen angår også en fremgangsmåte ved fremstilling The invention also relates to a method of manufacture
av beholderlokk med et manuelt inntrykkbart lukke, og det særegne ved denne fremgangsmåte er at der i lokket trykkes inn en forsenk- of a container lid with a manually impressionable closure, and the peculiarity of this method is that a recess is pressed into the lid
ning langs en sluttet linje, at et svekningslinjeskår frembringes ved preging i lokkplanets retning og at pregekantens side presses således at pregekantene bringes i det minste delvis i gjensidig berøring. ning along a closed line, that a weakening line cut is produced by embossing in the direction of the lid plane and that the side of the embossing edge is pressed so that the embossing edges are brought at least partially into mutual contact.
Det materiale som omgir det inntrykkbare lukke, som hensiktsmessig er knappformet, er således dannet av en innpressing ved hjelp av et trekkverktøy. Deretter blir materialet preget ved innpressingen for å svekke det på dette sted, hvoretter den pregede innpressing trykkes delvis flat for å lukke pregingen. Når det knappformede lukke utsettes for et trykk av brukerens finger, vil det bli revet ut av lokket og faller eller blir svingt ned i beholderen. Behandlingen av lokket er således utført at der ikke oppstår noen skarpe kanter; brukerens finger eller lepper vil derfor ikke bli skadet under åpningen av lukket eller drikkingen av beholderens innhold. The material that surrounds the impressionable closure, which is suitably button-shaped, is thus formed by pressing in using a pulling tool. The material is then embossed at the indentation to weaken it at this point, after which the embossed indentation is pressed partially flat to close the embossment. When the button-shaped closure is subjected to a pressure of the user's finger, it will be torn from the lid and fall or swing down into the container. The treatment of the lid is carried out in such a way that no sharp edges occur; the user's finger or lips will therefore not be injured during the opening of the closed or the drinking of the contents of the container.
Den vegg som begrenser innpressingen, behøver ikke preges helt rundt, således at lukket ikke vil bli helt adskilt fra lokket når det trykkes inn, men blir svingt ned i det indre av beholderen. The wall that limits the pressing in does not need to be embossed all the way around, so that the closure will not be completely separated from the lid when it is pressed in, but will be swung down into the interior of the container.
Konstruksjonen er således utført at der må utøves stør-re kraft, hvis det knappformede lukke skal rives opp fra beholderens innerside enn fra yttersiden, og resultatet av dette blir at der ved pasteuriseringen kan anvendes høye trykk. Lukkets peri-feri er meget kraftig fordi det inntil en viss grad er forsterket idet skåret er gjennombrutt og derpå igjen delvis lukket av en overlapping, hvoretter der på lokkets innerside kan anbringes en lakk for å tilveiebringe tilstrekkelig tetning. The construction is designed in such a way that greater force must be exerted if the button-shaped closure is to be torn open from the inside of the container than from the outside, and the result of this is that high pressures can be used during pasteurization. The lid's periphery is very strong because it is reinforced to a certain extent as the cut is broken through and then partially closed again by an overlap, after which a lacquer can be placed on the inside of the lid to provide a sufficient seal.
Oppfinnelsen skal forklares nærmere under henvisning The invention shall be explained in more detail under reference
til tegningen, hvis fig. 1 og 2 viser i perspektiv toppen av en blikkboks i lukket henholdsvis åpen tilstand, fig. 3 viser det første trinn under formingen av en kontrollert åpning, fig. 4 viser stanse- og pregeoperasjonen, fig. 5 viser lukking av svek-ningslin jen, og fig. 6 viser i større målestokk et snitt av den pregede og delvis gjennombrutte innpressing. to the drawing, if fig. 1 and 2 show in perspective the top of a tin can in a closed and open state, fig. 3 shows the first step during the shaping of a controlled opening, fig. 4 shows the punching and embossing operation, fig. 5 shows closure of the weakening line, and fig. 6 shows, on a larger scale, a section of the embossed and partially broken indentation.
På fig. 1 og 2 angir 10 den øvre del av en blikkbehol-der med en vanlig falset kant 12 mellom lokket 14 og beholderen 10. Et knappformet lukke 16 er fortrinnsvis rundt og anbragt i nærheten av falsen 12. Denne knapp har en nedpresset fordypning eller innpressing 18 rundt periferien. Lokket er forsynt med en svekningslinje uten fjernelse av materiale (se fig. 4) i en kon-veks vegg etterfulgt av en tilpressing (fig. 5), således at knappen 16 kan trykkes inn i beholderen som vist på fig. 2, idet den vesentligste del av knappen 16 rives ut av lokket og at den enten faller ned i beholderen eller blir hengende fast til lokkets innerside for å unngå at den blir kastet vekk, se fig. 2. Selv om knappen blir hengende fast til kanten, vil den ikke hindre brukeren i å drikke innholdet i boksen gjennom åpningen 19. In fig. 1 and 2 indicate 10 the upper part of a tin container with a regular folded edge 12 between the lid 14 and the container 10. A button-shaped closure 16 is preferably round and placed near the fold 12. This button has a depressed depression or indentation 18 around the periphery. The lid is provided with a weakening line without removal of material (see fig. 4) in a convex wall followed by a pressing (fig. 5), so that the button 16 can be pressed into the container as shown in fig. 2, in that the most important part of the button 16 is torn out of the lid and that it either falls into the container or is attached to the inside of the lid to prevent it from being thrown away, see fig. 2. Even if the button is stuck to the edge, it will not prevent the user from drinking the contents of the can through the opening 19.
Ifølge fig. 3, 4 og 5 anvendes der for fremstillingen According to fig. 3, 4 and 5 are used there for the preparation
av det knappformede lukke et verktøy som består av en underdel 20 med en oppadrettet omkringløpende, ringformet ribbe 22 av den of the button-shaped closure a tool consisting of a lower part 20 with an upwardly running, annular rib 22 of the
viste form. Verktøyets øvre del 24 har en omkringløpende fordypning 26 med stort sett rektangulært tverrsnitt. Når disse to verktøydeler trykkes mot hinannen på hver sin side av lokket 14, vil ribben 22 på den nedre verktøydel bevirke at der i lokkets underside presses opp et spor 28, se fig. 3. Dette spors øvre vegg når ikke helt inn i bunnen av fordypningen 26. Der vil også finnes et gap 30 mellom lokkets 14 underside og verktøyets nedre del 20. shown form. The upper part 24 of the tool has a circumferential recess 26 with a largely rectangular cross-section. When these two tool parts are pressed against each other on either side of the lid 14, the rib 22 on the lower tool part will cause a groove 28 to be pressed up in the underside of the lid, see fig. 3. The upper wall of this slot does not reach all the way into the bottom of the recess 26. There will also be a gap 30 between the underside of the lid 14 and the lower part 20 of the tool.
Ved neste trinn (fig. 4) benyttes den samme underdel 20 som tidligere, mens overdelen 24 erstattes med en ny overdel 32 som utgjør et pregestempel med en omkringløpende, nedadrettet, skjærende kant eller ribbe 40 som er bestemt til å foreta et innsnitt i sporets 28 yttervegg, hvilket spor vil befinne seg utenfor ribbens 22 og utenfor sporets 28 midtlinje. Ved hjelp av dette innsnitt vil materialet i lokket bli sterkt redusert uten å bli helt gjennombrutt. In the next step (fig. 4), the same lower part 20 is used as before, while the upper part 24 is replaced with a new upper part 32 which constitutes an embossing stamp with a running, downwards, cutting edge or rib 40 which is intended to make an incision in the groove 28 outer wall, which groove will be outside the rib 22 and outside the center line of the groove 28. With the help of this incision, the material in the lid will be greatly reduced without being completely broken through.
Det tredje trinn under behandlingen foregår ved hjelp av en tredje overdel 52 (fig. 5), mens lokket 14 fremdeles befinner seg på oversiden av underdelen 20. Overdelen 52 har en plan undre overflate 54 og anvendes til delvis å lukket det dannede innsnitt i sporets yttervegg. Verktøydelens overflate 54 vil trykke mot sporets avrundede yttervegg og bevirke at materialet i lokket på dette stéd vil trykkes ut til siden, således at spo-ret delvis lukkes for å forsterke det pregede område og hindre at der oppstår lekkasje. Den gjennomgående svekning 42 vil imidlertid fremdeles være tilstede og danne et omkringløpende riss mellom et i det vesentlige horisontalt kantparti 44 og et vertikalt kantparti 46. Den indre del av ytterveggen 28 befinner seg i en vinkel til lokkets 14 plan, mens den ytre del er stort sett vertikal. Hvis derfor verktøyet 34 skulle trenge for dypt inn, vil der ikke oppstå noen skade som tilfellet ville vært hvis den skjærende kant 34 skulle befinne seg ved det høyeste punkt 48 av ytterveggen 28. The third step during the treatment takes place with the help of a third upper part 52 (fig. 5), while the lid 14 is still located on the upper side of the lower part 20. The upper part 52 has a flat lower surface 54 and is used to partially close the formed incision in the groove outer wall. The tool part's surface 54 will press against the groove's rounded outer wall and cause the material in the lid to be pushed out to the side at this point, so that the groove is partially closed to reinforce the embossed area and prevent leakage. The continuous weakening 42 will, however, still be present and form a circumferential outline between an essentially horizontal edge part 44 and a vertical edge part 46. The inner part of the outer wall 28 is located at an angle to the plane of the lid 14, while the outer part is large set vertical. If, therefore, the tool 34 were to penetrate too deeply, no damage would occur as would be the case if the cutting edge 34 were to be at the highest point 48 of the outer wall 28.
Som vist på fig. 6 vil trykket mot svekningen 42 bli noe nedsatt når overdelen 52 løftes opp etter å ha foretatt de-former ingen, men forblir lukket selvom de sammenstøtende deler av deformeringen er noe uregelmessige, idet knappen vil bli noe utvidet i radial retning. Derved oppnås en meget bedre tetning As shown in fig. 6, the pressure against the weakening 42 will be somewhat reduced when the upper part 52 is lifted up after having made no deformation, but remains closed even if the colliding parts of the deformation are somewhat irregular, as the button will be somewhat expanded in the radial direction. This results in a much better seal

pen. Som det fremgår viser fig. 3, 4 og 5 beholderens lokk i omvendt stilling. Det knappformede lukke kan derfor ikke trykkes pretty. As can be seen, fig. 3, 4 and 5 the lid of the container in the inverted position. The button-shaped closure cannot therefore be pressed
ut fra beholderens innerside, fordi der ved hjelp av verktøyet 52 from the inside of the container, because there using the tool 52

Det fremgår imidlertid at knappen lett kan trykkes ut ved hjelp av en finger som virker på knappens ytterside, sett på fig. 1 og 2. an inclined edge is formed which holds the button in position. However, it appears that the button can easily be pushed out using a finger that acts on the outside of the button, seen in fig. 1 and 2.
