Den foreliggende opfindelse angår en fremgangsmåde ved fremstilling af en konservesdåse, der er fyldt med et fødemiddel, hvor dåsen har en generelt cylindrisk udvendig overflade og er forsynet med en rundtgående profilering, 5 dvs. i væggen har en fordybning, der strækker sig rundt langs omkredsen af dåsen.The present invention relates to a method of making a canned container which is filled with a foodstuff, wherein the can has a generally cylindrical outer surface and is provided with a circumferential profiling, i.e. in the wall has a recess extending around the circumference of the can.
En fremgangsmåde af denne art er kendt fra USA-pa-tentskrift nr. 3.117.873. Der beskrives heri en fremgangsmåde, ved hvilken dåsen efter fyldning og lukning sammentryk-10 kes aksialt i et sådant omfang, at dens indhold, især kornformede eller pulverformede produkter, såsom kaffe, giver væggen en væsentlig yderligere støtte. Det er indlysende, at styrken og stabiliteten af denne kendte dåse i væsentligt omfang opnås ved en mekanisk vekselvirkning mellem kræfter, 15 dvs. kombinationen af dåsen, dens låg og indholdet af den lukkede dåse.A method of this kind is known from U.S. Patent No. 3,117,873. There is disclosed herein a method in which the can, after filling and closing, is axially compressed to such an extent that its contents, especially granular or powdered products such as coffee, provide the wall with substantial additional support. It is obvious that the strength and stability of this known can is substantially achieved by a mechanical interaction of forces, i. E. the combination of the can, its lid and the contents of the closed can.
Det er formålet med den foreliggende opfindelse at tilvejebringe en fremgangsmåde til fremstilling af en dåse, hvis styrke og stabilitet alene er afhængig af selve dåsen.It is the object of the present invention to provide a method for producing a can whose strength and stability is dependent solely on the can itself.
20 Med henblik på at opnå dette er fremgangsmåden ifølge opfindelsen kendetegnet ved, at profileringen, forud for lukningen af dåsen ved hjælp af dens låg, i det væsentlige presses med dens kanter mod hinanden på en sådan måde, at afstanden mellem kanterne på profileringen er lille.In order to achieve this, the method according to the invention is characterized in that, before the closure of the can by means of its lid, the profiling is substantially pressed with its edges towards each other in such a way that the distance between the edges of the profiling is small. .
25 Ved fremgangsmåden tilvejebringes en dåse med en pro filering, der både sikrer dåsen mod at kollabere som følge af indtrykninger af væggen i tilfælde, hvor der er undertryk i dåsen, og som tillader, at et stort antal dåser stables oven på hinanden, uden at stablen som følge af deformering 30 af profileringen bliver ustabil.In the method, a can is provided with a profiling which both protects the can from collapsing due to wall impressions in cases where the can is under pressure and allows a large number of cans to be stacked on top of each other without the stack due to deformation 30 of the profiling becomes unstable.
Opfindelsen skal nu beskrives under henvisning til tegningen, der viser en vilkårligt valgt udførelsesform. På tegningen viser:The invention will now be described with reference to the accompanying drawing which shows a randomly selected embodiment. In the drawing:
Fig. 1 en cylindrisk konservesdåse med en profile-35 ring, der strækker sig omkring dåsens omkreds, fig. 2 en detalje II på fig. 1, fig. 3 den på fig. 1 viste dåse i den tilstand, hvor profileringens kanter i det væsentlige er presset mod hinan-FIG. 1 is a cylindrical canister with a profile extending around the circumference of the can; FIG. 2 shows a detail II in FIG. 1, FIG. 3 shows the one shown in FIG. 1 in the state in which the edges of the profiling are substantially pressed against each other.

2 den, og fig. 4 viser en detalje IV af fig. 3.2, and FIG. 4 shows a detail IV of FIG. Third
Fig. 1 viser en cylindrisk konservesdåse 1 med en cylindrisk væg 3, der er forsynet med en profilering 2# der 5 strækker sig omkring omkredsen.FIG. 1 shows a cylindrical canister 1 with a cylindrical wall 3 provided with a profiling 2 # which extends around the circumference.
Fig. 2 viser profileringen 2 i forstørret målestok. Pilene 4 viser afstanden mellem profileringens kanter.FIG. 2 shows the profile 2 on an enlarged scale. Arrows 4 show the distance between the edges of the profiling.
Fig. 3 viser den samme dåse 1. I den tilstand, der er vist på fig. 3, er profileringens 2 kanter imidlertid pres-10 set mod hinanden. For at angive forskellen fra fig. 1 er profileringen betegnet med referencesymbolet 2'. Det bør bemærkes, at presningen af kanterne mod hinanden kan ske i et separat produktionstrin, hvor der udøves en aksialkraft på dåsen enten før eller efter fyldning og lukning af denne el-15 ler som et resultat af det fremkomne undertryk i dåsen på grund af fyldning af dåsen med en varm masse, efterfølgende lukning af dåsen og efterfølgende afkøling af den fyldte dåse.FIG. 3 shows the same can 1. In the condition shown in FIG. 3, however, the edges of the profiling 2 are pressed against each other. To indicate the difference from FIG. 1, the profiling is indicated by the reference symbol 2 '. It should be noted that the pressing of the edges against each other can take place in a separate production step where an axial force is exerted on the can either before or after filling and closing this or as a result of the resulting underpressure in the can due to filling. of the can with a hot mass, subsequently closing the can and subsequently cooling the filled can.
Fig. 4 viser profileringen 2' i en forstørret måle-20 stok. Afstanden 4’ mellem kanterne er, som det fremgår ved en sammenligning mellem fig. 4 og fig. 2, betydeligt mindre end den afstand, der er betegnet med 4 på fig. 2. Når man stabler en flerhed af dåser, kan kanterne blive presset mod hinanden, således at aksialmodstanden bliver den samme som 25 hos en dåse, der ikke er forsynet med en profilering.FIG. 4 shows the profiling 2 'in an enlarged scale. The distance 4 'between the edges is, as is apparent from a comparison of FIG. 4 and FIG. 2, considerably less than the distance indicated by 4 in FIG. 2. When stacking a plurality of cans, the edges may be pressed against each other such that the axial resistance is the same as that of a can not provided with a profiling.
Tilstedeværelsen af en profilering er imidlertid af vital betydning, hvis dåsen skal have stor modstand mod at kollabere, dvs. at der opstår indtrykninger som følge af et undertryk i dåsen på grund af, at produkter i varm tilstand 30 er fyldt i dåsen, der derefter er lukket og er blevet afkø let. Profileringen tjener under disse forhold som armeringselement. Den resulterende reduktion i aksial stabilitet undgås ifølge opfindelsen ved i det væsentlige at presse kanterne af profileringen sammen mod hinanden. Dette forklarer, 35 hvorledes den aksiale stabilitet bliver lige så stor som på en dåse, der ikke har en profilering.However, the presence of a profiling is of vital importance if the can is to have great resistance to collapse, ie. that impressions arise as a result of a vacuum in the can due to the fact that products in hot state 30 are filled in the can which is then closed and cooled easily. Under these conditions, the profiling serves as a reinforcing element. The resultant reduction in axial stability is avoided according to the invention by substantially pressing the edges of the profile together. This explains how the axial stability becomes as great as a can that does not have a profile.
Det skal bemærkes, at afstanden 4’ også kan være nul.It should be noted that the distance 4 'may also be zero.
Til opnåelse af tilfresstillende stabelbarhed er det imid-In order to achieve satisfactory stackability, however,

Opfindelsen er ikke begrænset til en konservesdåse 5 med kun én indskæring eller indsnævring af den beskrevne type. Der kan også anvendes et andet antal af indskæringer eller profileringer.The invention is not limited to a canning box 5 having only one cut or narrowing of the type described. Another number of notches or profiles may also be used.
Andre former for profileringer giver det samme ønskede resultat. Derfor er opfindelsen ikke begrænset til den 10 form, der er vist på tegningen.Other types of profiling give the same desired result. Therefore, the invention is not limited to the shape shown in the drawing.
