Description
Oppfinnelsen angår en aerosol-beholder av metall som angitt i inledningen til vedlagte hovedkrav. The invention relates to an aerosol container made of metal as stated in the introduction to the attached main claims.
Dessuten angår oppfinnelsen en fremgangsmåte til fremstilling av en slik aerosol-beholder, hvor det langs den nedre kant av den sylindriske beholdermantel først formes et ringformet spor, hvis diameter er mindre enn mantelens utvendige diameter, og deretter festes falsekanten av en bunn i det ringformede spor ved falsing. Furthermore, the invention relates to a method for producing such an aerosol container, where an annular groove is first formed along the lower edge of the cylindrical container jacket, the diameter of which is smaller than the outer diameter of the jacket, and then the folded edge of a bottom is fixed in the annular groove by folding.
Det er allerede kjent aerosolbeholdere av denne type med påsatt bunn (CH-PS 525 820) , hvor en flens ved den nedre ende av beholderarantelen, et med denne samvirkende ringformet område av bunnen og en mellom disse anordnet tetningsring er valset i hverandre radialt utover på en slik måte at det fremkommer en i det vesentlige sirkelbueformet flens som er forsenket i en på beholdermantelens omkrets anordnet renne. På denne måte har den todelte aerosolbeholder en gjennomgående,, fremspringsfri ytre om-kretsflate på sin sylindriske omkrets og allikevel er den i ril-len eller rennen liggende flens synlig utenfra. Aerosol containers of this type with an attached bottom (CH-PS 525 820) are already known, where a flange at the lower end of the container flange, an annular area of the bottom interacting with this and a sealing ring arranged between these are rolled into each other radially outwards such a way that a substantially circular arc-shaped flange is produced which is recessed in a channel arranged on the circumference of the container jacket. In this way, the two-part aerosol container has a continuous, protrusion-free outer peripheral surface on its cylindrical circumference and yet the flange lying in the groove or channel is visible from the outside.
Til grunn for oppfinnelsen ligger den oppgave ved en aerosolbeholder av den art som er beskrevet i innledningen til hovedkravet, å gjøre de i hverandre gripende falsekanter av beholdermantelen og bunnen usynlige utenfra og samtidig forsterke falsekantene og deres innbyrdes feste slik at noen riving eller brudd av metallet unngåes med sikkerhet når den innover buede beholderbunn buer seg utover under virkningen av et økt innvendig trykk. The invention is based on the task of an aerosol container of the type described in the introduction to the main claim, to make the interlocking folded edges of the container jacket and bottom invisible from the outside and at the same time to reinforce the folded edges and their mutual attachment so that any tearing or breakage of the metal is safely avoided when the inwardly curved container base curves outwards under the action of an increased internal pressure.
Denne oppgave løses ifølge oppfinnelsen ved hjelp av de trekk som er angitt i karakteristikken til vedlagte krav 1. This task is solved according to the invention with the help of the features indicated in the characteristics of the attached claim 1.
De på denne måte oppnådde tekniske fordeler består i at aerosolbeholderen har en gjennomgående glatt sylindrisk omkrets-vegg og dens bunn er så fast forbundet med beholdermantelen at det til avrivning av bunnen nødvendige trykk er større enn det trykk, hvorunder bunnen buer seg utover. Denne betingelse, som kreves for de fleste praktiske anvendelser av slike metalliske aerosolbeholdere, kunne hittil vanligvis bare oppfylles ved en bunn av hvitblikk. Ifølge oppfinnelsen er det imidlertid uten videre mulig å fremstille både den sylindriske beholdermantel og den påsatte bunn av aluminium på en slik måte at de nevnte betin-gelser oppfylles. The technical advantages achieved in this way consist in the fact that the aerosol container has a continuous smooth cylindrical peripheral wall and its bottom is so firmly connected to the container jacket that the pressure required to tear off the bottom is greater than the pressure under which the bottom bends outwards. This condition, which is required for most practical applications of such metallic aerosol containers, could heretofore usually only be fulfilled by a bottom made of tin. According to the invention, however, it is easily possible to produce both the cylindrical container shell and the attached bottom of aluminum in such a way that the aforementioned conditions are met.
Fremgangsmåten ifølge oppfinnelsen til fremstilling av en aerosolbeholder er angitt i vedlagte krav 2. The method according to the invention for producing an aerosol container is stated in the attached claim 2.
Denne fremgangsmåte har den fordel at den omfatter bare få og lett gjennomførbare fremgangsmåtetririn. This method has the advantage that it comprises only a few and easily implemented process steps.
Oppfinnelsen skal beskrives nærmere i det følgende under henvisning til tegningene som viser en utførelse av oppfinnelsen i forskjellige trinn uhdér fremstillingen, idet fig. 1 viser en beholder etter deh første operasjon og bunnen før sin befestigelse samt en detalj ved den nedre kant, fig. 2 viser den samme beholder og en detalj av den nedre kant etter en annen operasjon, fig. 3 viser den' samme beholder og en detalj av dén hedtfe kant etter eri tredje operasjon og fig. 4 viser den samme beholder ferdig og en detalj av den nedre kant etter en fjerde operasjon. The invention shall be described in more detail in the following with reference to the drawings which show an embodiment of the invention in various stages during the manufacture, as fig. 1 shows a container after the first operation and the bottom before its attachment as well as a detail at the lower edge, fig. 2 shows the same container and a detail of the lower edge after another operation, fig. 3 shows the same container and a detail of the heated edge after the third operation and fig. 4 shows the same container finished and a detail of the lower edge after a fourth operation.
Ved foten av en rørformet mantel av aluminium 1 vist på fig. 1 og fremstilt ved stansing med en øvre stumpkjegleformet ende 2 og en ombøyd kant 3, på hvilken skal festes en ventil ved hjelp av den fremgangsmåte som anvender ekspandering, danner man en hals 4 ved trykkfalsing innover av mantelen 1 slik at diamete-ren av deh nedre kant 5 av denne hals vil være tilnærmet lik dia-meteren av den sylindriske mantel 1. At the foot of a tubular casing of aluminum 1 shown in fig. 1 and produced by punching with an upper truncated cone-shaped end 2 and a bent edge 3, on which a valve is to be attached using the method that uses expanding, a neck 4 is formed by pressure folding inwards of the mantle 1 so that the diameter of the lower edge 5 of this neck will be approximately equal to the diameter of the cylindrical mantle 1.
Man påfører deretter på kanten 5 en bunn 6 som har et buet parti 6a, et sylindrisk parti 6b, en flens 6c og en kant 6d tilnærmet parallell med det sylindriske parti 6b, og fester denne bunn ved hjelp av en konvensjonell falseoperasjon, idet flensen 6c da brettes oppover på figuren. Bunnens dimensjoner i forhold til den rørformede mantel 1 er slik valgt at dens utvendige diameter etter.falsing er tilnærmet lik den utvendige diameter av den sylindriske vegg 1 minus fire ganger tykkelsen av denne vegg, hvilket vil si at den radiale sammentrekning av bunnen under fal-singen er omkring to ganger tykkelsen av den sylindriske vegg 1, slik det fremgår detaljert av fig. 2, mens dybden og formen av halsen 4 er slik at denne hals slutter seg inntil formen av bunnens partier 6b og 6c og på denne måte tillater innfelling av bunnen i mantelen og sikring av en tilfredsstillende fals. One then applies to the edge 5 a bottom 6 which has a curved part 6a, a cylindrical part 6b, a flange 6c and an edge 6d approximately parallel to the cylindrical part 6b, and attaches this bottom by means of a conventional folding operation, the flange 6c then fold upwards on the figure. The dimensions of the bottom in relation to the tubular casing 1 are chosen so that its outside diameter after folding is approximately equal to the outside diameter of the cylindrical wall 1 minus four times the thickness of this wall, which means that the radial contraction of the bottom during folding the singe is about twice the thickness of the cylindrical wall 1, as can be seen in detail from fig. 2, while the depth and shape of the neck 4 is such that this neck joins the shape of the bottom parts 6b and 6c and in this way allows embedding of the bottom in the mantle and securing a satisfactory seam.
I et tredje trinn vist på fig. 3 skyver man bunnen 6 inn i det indre av beholderen ved å utøve et trykk mot bunnen i pilens F retning ved hjelp av et verktøy som har et avrundet hode. svarende til bunnens bueform. Under denne operasjon blir falsen ved hjelp av bunnen ført innover i det indre av beholderen uten synlig svekning eller løsriving. Mantelveggen 1 deformeres i virkeligheten slik at den følger forskyvningen av falsen og danner en fold eller brett 7. Dannelsen av denne fold er mulig på grunn av de relative dimensjoner som er valgt for bunnen og mantelen. In a third step shown in fig. 3, the bottom 6 is pushed into the interior of the container by applying pressure to the bottom in the direction of the arrow F using a tool that has a rounded head. corresponding to the arch shape of the bottom. During this operation, the seam is guided by the bottom into the interior of the container without visible weakening or detachment. The mantle wall 1 is actually deformed so that it follows the displacement of the fold and forms a fold or fold 7. The formation of this fold is possible because of the relative dimensions chosen for the base and the mantle.
I den stilling som er vist på fig. 3, er falsen allerede skjult i det indre av mantelen 1. Det er dessuten mulig å an-vende folden eller bretten 7 til å forsterke befestigelsen av bunnen ved f.eks. ved valsing å brette folden 7 mot halsen slik at In the position shown in fig. 3, the fold is already hidden in the interior of the mantle 1. It is also possible to use the fold or fold 7 to reinforce the fastening of the bottom by e.g. when rolling to fold the fold 7 towards the neck so that
o o
der dannes en omramming 7' som vist på fig. 4. Man ser at falsen vil støtte seg mot denne omramming slik at for å bevirke løsriv-ning av bunnen må trykket i beholderens indre først deformere denne omramming 7' og trykke bunnen ut til den stilling som er vist på fig. 2, før det kan påvirke falsen. Det vil dessuten lett forstås at bunnen vil bli ødelagt før den vil bli revet løs, hvilket er en generell betingelse krevet av brukerne av slike beholde-re som er bestemt til å inneholde aerosolprodukter. a frame 7' is formed as shown in fig. 4. It can be seen that the seam will lean against this framing so that in order to cause the bottom to detach, the pressure inside the container must first deform this framing 7' and push the bottom out to the position shown in fig. 2, before it can affect the hem. It will also be easily understood that the bottom will be destroyed before it will be torn loose, which is a general condition required by the users of such containers which are intended to contain aerosol products.
