Definitions

  • the present invention relates on the one hand to a method of manufacturing a metallic package of generally prismatic shape and on the other hand to a metallic package obtained by this method.
  • the rounded parts of the fallen edge thus formed have a metal deficit compared to the straight parts of the fallen edge.
  • a dropped edge formed on a neck formed on the end of a tubular body of substantially polygonal cross section has a very irregular contour unsuitable for crimping a face attached to the fallen edge.
  • the object of the invention is to remedy the defects which arise during the formation of an edge which has fallen onto a constriction formed on a tubular body of substantially polygonal cross section.
  • a subject of the invention is also a metallic packaging of generally prismatic shape, of the type comprising a tubular metallic body of substantially polygonal cross section delimiting lateral faces of the packaging connected together by rounded corners, and a face forming a top or bottom of the packaging crimped onto one end of the body, characterized in that the surface forming the top or bottom is crimped onto a neck formed at the corresponding end of the body.
  • a tubular metallic body 10 as first shown in FIG. 1 is manufactured.
  • the body 10 has a substantially rectangular cross section and is intended to delimit lateral faces 12 of the metal packaging.
  • the lateral faces 12 are interconnected by rounded corners 14.
  • the tubular body 10 is manufactured in a manner known per se from a sheet of metal sheet, which is rolled, then welded so as to form a ferrule and finally expanded so as to obtain a substantially rectangular cross section.
  • the lower end of the body 10 is closed by forming a lower fallen edge 16 on this lower end, then by crimping on this edge 16 an attached metal face (not shown in the figures) forming the bottom of the packaging. .
  • the bottom is crimped on the lower dropped edge either immediately after this fallen edge is formed or later.
  • FIGS. 3 to 5 there is formed, near the upper end of the body 10 and on each of the corners 14 of this body, a bead 18 projecting radially outward from the body, with respect to the longitudinal direction of this body.
  • the beads 18 may extend radially inward of the body.
  • the beads 18 are all substantially the same distance from the upper end of the body and have the diametrical planes of the body 10 as their plane of symmetry.
  • the beads 18 are formed using known means so as to extend parallel to a transverse plane of the body 10 substantially along the same angular sector as the corresponding rounded corners.
  • a constriction 20 and an upper fallen edge 22 extending this constriction are formed on the upper end of the body 10, using known means, as shown in FIG. 6.
  • the neck 20 is connected to the rest of the body 10 by an inclined connecting part 20L.
  • This part 20L is spaced axially from the beads 18 by a distance D preferably between 0 and 3 mm.
  • the distance D is non-zero, while in the variant shown in FIG. 7, the distance D is zero so that the inclined connecting part 20L directly extends the beads 18.
  • the axial depressions E create metal deficits making it possible to subsequently compensate for the excess of metal appearing at the rounded corners of the body 10 when the constriction 20 is formed before forming the upper fallen edge 22.
  • the dimension of the beads can be easily determined according to the excess metal to be compensated during the formation of the necking followed by the upper fallen edge.
  • the contour of the fallen edge 22 thus obtained is regular, that is to say that its dimension in a radial direction relative to the body 10 is substantially identical both in the rounded parts and in the straight parts of the fallen edge.
  • the contour of the upper dropped edge 22 is regular, the top to be crimped can be easily positioned on the fallen edge and the setting obtained thereafter is of very good quality.
  • the metal packages obtained according to the method of the invention described above are easily stackable on top of each other. Indeed, the lower end of a package is nestable on the narrowed upper end of another similar package.
  • the invention is not limited to the exemplary embodiments described above.
  • tubular body can have any substantially polygonal cross section, other than rectangular.
  • constriction can be formed either on the upper or lower end of the packaging.
