Accordingly, the details of the configuration of the can shell 10' include a chuckwall upper wall portion 32' having an angle A2 relative to the center axis of at least 16° and preferably within the range of 25° to 30°.
  • the lower wall portion 34' of the chuckwall forms an angle A3 which is about 15°.
  • the inner wall 38' of the crown 42 forms an angle A4 preferably within the range of 5° to 30° and preferably about 16°.
  • the inner wall 17' of the countersink 18' forms an angle A6 which is greater than 10° and about 13°.

  • the radius R8 of the curved inner panel wall 16' is substantially greater than the width W1 of the countersink 18' and is about .049 inch.
  • the crown 42' of the shell 10' has a height C1 within the range of
  • the overall diameter D8 of the shell 10' is about 2.337 inch, and the diameter D7 to the junction 46' is about 2.036 inch.
  • the inner bottom diameter D6 of the outer countersink wall 24' is about 1.910 inch, and the difference W2 between D7 and D6 is greater than the countersink width W1 , or about .063 inch.
  • the diameter D9 for the center of the radius -R8 is about 1.731 inch. It is understood that if a different diameter shell is desired, the diameters D6-D9 vary proportionately.
  • the height H5 of the center panel 12' above the bottom of the countersink 18' is within the range of .070 inch and .110 inch and preferably about .078 inch.
  • the height H6 of the shell 10' between the top of the center panel 12' and the top of the crown 42' is within the range of .125 inch and .185 inch, and preferably about .149 inch.

  • the configuration and relative shallow profile of the can end also provides for a significant reduction of over .040 inch in the diameter of the circular blank which is used to form the shell.
  • This reduction results in a significant reduction in the width of aluminum sheet or web used to produce the shells, thus a reduction in the weight and cost of aluminum to form can ends, which is especially important in view of the large volume of can ends produced each year.
  • the shell 10 or 10' also minimizes the modifications required in the tooling existing in the field for forming the double- seamed crown 70 or 70'.
  • the only required modification in the tooling for forming the double-seamed crown is the replacement of a conventional or standard double-seaming chuck with a new chuck having the frusto-conical mating surface 62 and the generally cylindrical surface 68 on the bottom portion 64 which extends into the countersink and engages the outer countersink wall.
  • Conventional double-seaming chucks commonly have the slightly tapered surface 58 which extends at an angle of about 4° with respect to the center axis of the double-seaming chuck.

Abstract

L'invention concerne une enveloppe de canette en aluminium étiré comportant une couronne périphérique reliée par sertissage double à une section d'extrémité d'un corps de canette en aluminium pour former une extrémité de canette comportant un panneau central sensiblement plat relié, par une paroi courbe du panneau, à une paroi interne d'un évasement conique annulaire en forme de U. Cet évasement conique présente une paroi externe sensiblement cylindrique et une largeur interne de dimension inférieure au rayon de ladite paroi du panneau. La paroi externe de l'évasement conique est reliée à une section de paroi inférieure d'une paroi tronconique pour mandrin, au niveau d'une jonction située en-dessous du panneau central, et une section de paroi supérieure de ladite paroi à mandrin s'étend jusqu'à une paroi interne de la couronne selon un angle d'au moins 16° par rapport à l'axe central. Dans un mode de réalisation de la présente invention, la paroi pour mandrin comporte une section intermédiaire, ascendante, courte, sensiblement verticale reliant lesdites sections de paroi, et la largeur interne du fond de l'évasement conique mesure moins de 0,4 pouce.
