ABSTRACT:
A method and apparatus for seaming a can end to a can body and a can made thereby. The can end has a side wall forming an angle in the range of about 12.degree. to 15.degree.. A seaming chuck is inserted into the can end adjacent its side wall. The seaming chuck has upper and lower walls. The upper wall is essentially cylindrical or slightly negatively tapered. The lower wall is disposed at an angle very close to that of the can end side wall so that the upper and lower chuck side walls form an obtuse angle in the range of about 162.degree. to 168.degree.. A can seamed using such a chuck will have a segmented, kinked side wall comprising upper and lower substantially straight sections intersecting at a circumferentially extending crease and forming an obtuse angle.
