Definitions

  • the object of the invention is to introduce certain improvements in the forming of one end of a cylindrical metal container, said end being called “bottom”, in opposition to the "top” end, that is normally opened to empty the container.
  • metal cans metal containers
  • the can had as a basic feature the fact that its bottom rim was flush with the outside body surface, and that the overlapping surfaces of end and body were flat and laying in parallel plans, perpendicular to the axis x-x′ of the can (Fig. 3) ⁇
  • FR-A-410,543 shows a metal container having a rim with a substantially toroidal configuration with the lower edge of the can body forming convolutions that are alternate and adjacent with the edge of an end and are not parallel with the base plane.
  • the sealing according to this state of the art can only be used with very soft materials for the container, e.g. card board.
  • a metal container according to the state of the art as described in GB-A-2,166,410 has the following draw-backs:
  • FIGs. 1 and 2 show that prior art containers (metal cans) such as manufactured at present by can producers and delivered to packers for filling and sealing with their products (such as food preserves or others) consist of a cylindrical body 1 with the top side flared outwards in a flange 2 in order to permit the final double seaming of the top end 3 after filling in the product.
  • prior art containers metal cans
  • their products such as food preserves or others
  • the bottom end 5 is double seamed, resulting in a labyrinth configuration commonly called "double seam" 8 in which adjacent layers of body and end materials lay concentrically along substantially cylindrical surfaces, said surfaces having axes x-x′ that are parallel to the body's cylindrical surface generatrix.
  • the can in Fig. 3 has a flange 2 on the top side 9 of the can body normally turned outward and the bottom part 6 of said body turned inward 4 in such a way that a can end 5 applied to the body from the inside, as shown by the dotted line drawing at "t", is engaged by its outer rim 7 with a resulting seam being obtained, said seam having a labyrinth configuration in which adjacent layers of can body and can end material lay in substantially parallel planes, said planes being parallel to the plate P-H of the can base and perpendicular to the can axis x-x′.
  • the improved metal container (metal can) that is the subject of the present invention, Figs. 4 and 5, has a new configuration of the bottom rim 13 in which the outer rim 10 of a can end 12 that engages the lower part 15 of the can body 14 has to convey protrusions 10a-10d and a concave surface 10b in between, that, together with adjacent layers formed by the can body-bottom part 15-15a and the outer edge 10c of said can end 12, provide a labyrinth configuration with a substantially toroidal outside surface.
  • the can body edge 15a is in contact and applies pressure against a sealing compound deposit applied to can end 12 on its outside surface before the seaming operation.
  • Said can end is of a type described in Brazilian patent application PI 860.5741 and consists of a central panel defined by an annular wall depending from the periphery thereof to define a concave recess; an annular portion extending radially outward from the periphery of the annular wall, and a down turned edge portion so arranged that the down turned edge, annular portion and annular wall define a channel in which is placed a gasket in the form of a lining compound, the lining compound being placed in a corner defined by the down turned edge and the annular portion, on the side of said end that is opposite to the side which, after assembly, constitutes the inside of the can.
  • the toroidal rim basis that is the plan where the convex protrusions 10a and 10d lie, may be parallel to plan PM (Fig. 4) that is tangent to the outside rim surface, as shown in Figs. 4 and 5, but it may also lay at an angle, forming a conical surface, without changing the basic characteristic of the curved labyrinth configuration.
  • FIG. 5 A preferred configuration of the container is shown in Fig. 5, where the lower part of the can body 15, adjacent to the seam area, is shaped into a conical surface 17 allowing this part to fit into the double seamed top of another can, making it "stackable", that is, making it easier to stack for display or handling purposes.
  • Said conical surface must be such that distance d, measured from the beginning of the seam to the cylindrical surface, will be at least equal to the thickness of the plate used for making the can body plus thickness of the can top end.

Claims (3)

1. Récipients métalliques réalisés en trois pièces avec un corps soudé longitudinalement, ayant à sa partie supérieure un rebord évasé vers l'extérieur (16) pour permettre la double jonction d'une extrémité après remplissage du récipient, avec un fond (12) assemblé de l'intérieur sur un bord de corps (15) retourné vers l'intérieur pour former une configuration de labyrinthe avec des couches adjacentes de matériau à l'intérieur d'un rebord (13), caractérisés en ce que ledit rebord (13) a une configuration sensiblement torique, que le rebord a un diamètre plus petit que le diamètre interne du corps (14) dans sa partie médiane, que le corps (14) est incurvé vers l'intérieur à sa partie de bord inférieur en direction du rebord (13), et en ce que les couches formant des replis (10b, 10c, 15a) sont parallèles entre elles et repliées ensemble de façon convexe de façon que la partie centrale du rebord (13) soit plus basse que ses bords, et que la forme externe du rebord épouse la forme de la partie de bord du corps (14).
2. Récipients métalliques selon la revendication 1, caractérisés en ce que la configuration en labyrinthe entre l'extrémité de fond (12) et le bord (15) du corps coopérent hermétiquement au moyen d'une couche élastique d'un matériau d'étanchéité approprié (11).
3. Récipients métalliques selon les revendications 1, et 2, caractérisés en ce qu'une surface conique (17) convergeant vers le bas, est prévue entre la partie médiane du corps (14) et la partie du corps (14) recourbée vers l'intérieur.
