Definitions

  • the invention refers to a water-tight metallic container according to the first part of claim 1 wherein the bending of metallic containers is to be compensated aiming to prevent the usual bending that normally appears in the metallic containers during the expansion operations carried out to obtaining or manufacturing such containers.
  • the seam-folding system of the inventive container which compensates the bending can be applied to all kind of metallic containers of a shape that can be either trunco-pyramidal, parallelopipedic, elliptical, etc.
  • the object of the invention is to absorb or compensate the differences in the length between the hooks at the corners and those intermediate ones produced during the seam-folding of the container and its bottom.
  • the object is solved with a water-tight metallic container according to claim 1 and a process according to claim 4.
  • the water-tight container according to claim 1 has a seam-folding system to compensate the bending, which achieves that during the seam-folding operation the defect mentioned-above is corrected which, in turn, will save the operations 1 and 3 referred to above and which are prior to the seam-folding operation.
  • a metallic container 1 presents a bottom 2 and a perimetric flange 3 for seam-folding 4 purposes represented in another area of the same figure which also shows the bending 5 before the seam-folding.
  • Figures 4 and 5 show the sections of the compensating seam-folding according to the invention, while figure 3 shows the conventional seam-folding with no differences of length between its hooks, i.e. those which intervene in the seam-folding between such conventional container 1' and the relevant bottom 2'.
  • the configuration of the new seam-folding enables to reduce the height of the hook 6' by means of corrugations that shorten its length and, on the other hand, the hook 7' should be kept completely straight, compressed and compact to avoid that the bottom 2 is detached from the body 1 while keeping the referred water-tightness level.

Claims (5)

  1. Wasserdichter Metallcontainer, welcher einen gedehnten Körper (1) umfasst, der einen seitlichen umlaufenden Bund (3), einen Boden (2) und eine zwischen dem genannten Boden (2) und dem genannten seitlichen umlaufenden Bund (3) eingerastete Dichtung (4) aufweist, derart, dass in der genannten Dichtung (4) ein eingerasteter Teil des genannten Bundes (3) angeordnet ist und an einer umlaufenden Schleife des genannten Bodens (2) übersteht, dadurch gekennzeichnet, dass der genannte seitliche umlaufende Bund (3) eine ungleiche Breite aufweist, die als Knick (5) bezeichnet wird, welche in den Ecken breitere Haken (7') und in den dazwischen liegenden Teilen schmälere Haken (6') aufweist; dass die genannte Schleife eine konstante Höhe (10) aufweist, die im wesentlichen der Höhe der genannten breiteren Haken (7') entspricht, so dass die letzteren vollständig über die genannte Schleife vorstehen, während die schmäleren Haken (6') nicht vollständig über die genannte Schleife vorstehen; und dass die genannte eingerastete Dichtung (4) in einem Bereich (8) zusammengepresst ist, der der Höhe der schmäleren Haken (6') entspricht.
  2. Wasserdichter Container nach Anspruch 1, dadurch gekennzeichnet, dass die genannte eingerastete Dichtung (4) einen gestuften und gerippten Bereich (9) aufweist, um die Höhe der genannten Haken (6', 7') zu verringern.
  3. Wasserdichter Container nach Anspruch 1 oder 2, dadurch gekennzeichent, dass die Höhe der genannten schmäleren Haken (6') der halben Höhe der genannten Schleife entspricht.
  4. Verfahren zur Herstellung eines wasserdichten Metallcontainers nach einem der vorgenannten Ansprüchen, wobei dieses folgende Stufen umfasst:
    den Körper (1) des genannten Containers zu dehnen, um so durch den sogenannten Knick (5) eine ungleiche Breite des seitlichen umlaufenden Bundes (3) desselben zu erreichen, mit breiteren Bereichen in den Ecken (7) und schmäleren Bereichen (6) in den dazwischen liegenden Teilen,
    wobei die umlaufende Schleife des Bodens (2) über dem genannten seitlichen umlaufenden Bund eingerastet wird, derart, dass die genannte Schleife eine konstante Höhe (10) aufweist, die im wesentlichen der Länge der Haken (7') entspricht, die sich aus den genannten breiteren Bereichen (7) ergibt, wobei die genannte Schleife die genannten breiteren Haken und die schmäleren Haken (6') aufnimmt, welche sich aus den genannten schmäleren Bereichen (6) ergeben, so dass die genannten breiteren Haken (7') die genannte Schleife vollständig überlappen, während die genannten schmäleren Haken (6') diese nicht vollständig überlappen, und
    einen Bereich (8) der genannten eingerasteten Dichtung (4) zusammenzupressen, wobei dieser der Höhe der kürzeren Haken (6') entspricht.
  5. Verfahren nach Anpruch 4, welches die Stufe der Rippung eines Bereichs (9) der genannten eingerasteten Dichtung (4) umfasst, um so die Höhe der genannten Haken (6', 7') zu verringern.
