Abstract
A drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by a curved panel wall to an inner wall of an annular U-shaped countersink. The countersink has a generally cylindrical outer wall and an inner width less than the radius of the panel wall. The outer wall of the countersink connects with a lower wall portion of a frustoconical chuckwall at a junction below the center panel, and an upper wall portion of the chuckwall extends to an inner wall of the crown at an angle of at least 16~ with the center axis. In one embodiment, the chuckwall has an intermediate generally vertical short riser portion connecting the wall portions, and the inner bottom width of the countersink is less than .040 inch.
Claims (17)
1. A sheet metal can shell having a vertical center axis and a curled peripheral crown adapted to be double-seamed to an end portion of a formed sheet metal can body, said shell comprising a circular center panel connected by a curved panel wall to an inner wall of a countersink having a U-shaped cross-section and an outer wall, a frusto-conical chuckwall having a wall portion extending at an angle greater than 16° relative to said center axis and connected to said outer wall of said countersink at a first junction, said crown having an inner wall connected to said chuckwall at a second junction, said countersink having a radius of curvature substantially smaller than a radius of curvature of said curved panel wall, said first junction being spaced below the level of said center panel with a vertical distance between said first junction and said second junction being greater than the width of said countersink at the bottom of said countersink between said inner and outer walls of said countersink, and said radius of curvature of said curved panel wall being greater than said width of said countersink.
2. A shell as defined in claim 1 wherein said difference in diameters between said inner wall of said crown and said outer wall of said countersink is substantially greater than said radius of curvature of said countersink.
3. A shell as defined in claim 1 wherein said wall portion of said frusto-conical chuckwall extends at an angle between 25° and 30°
relative to said center axis.
relative to said center axis.
4. A shell as defined in claim 1 wherein said shell has an overall height between said crown and said countersink between .195 inch and .265 inch.
5. A shell as defined in claim 1 wherein said countersink has a generally flat bottom wall and curved inner and outer corner walls connecting said bottom wall to said inner and outer walls of said countersink, and each of said corner walls has a radius of curvature less than a radial width of said bottom wall.
6. A shell as defined in claim 1 in combination with a double seaming chuck having an axis of rotation common with said center axis of said shell, said seaming chuck including an annular portion projecting into said countersink and having an outer surface engaging said outer wall of said countersink, said seaming chuck having a frusto-conical surface engaging said chuckwall, and said seaming chuck having a surface engaging said inner wall of said crown.
7. A sheet metal can shell having a vertical center axis and a curled peripheral crown adapted to be double-seamed to an end portion of a formed sheet metal can body, said shell comprising a circular center panel connected by a curved panel wall to an inner wall of a countersink having an outer wall and a U-shaped cross-sectional configuration, a generally frusto-conical chuckwall extending from said outer wall of said countersink and having an inclined upper wall portion extending at an angle of at least 16° relative to said center axis, said chuckwall having an inclined lower wall portion connected to said outer wall of said countersink at a junction disposed substantially below the level of said center panel, said crown having an inner wall connected to said upper wall portion of said chuckwall, said countersink having a radius of curvature substantially smaller than a radius of curvature of said curved panel wall, and the width of said countersink at the bottom of said countersink between said inner and outer walls of said countersink being less than said radius of curvature of said panel wall and less than .040 inch.
8. A shell as defined in claim 7 wherein the difference in diameters between said inner wall of said crown and said outer wall of said countersink is greater than said width of said countersink.

10. A shell as defined in claim 7 wherein a generally vertical short riser wall portion connects said upper and lower wall portions of said chuckwall.
11. A shell as defined in claim 7 wherein said inclined lower wall portion of said chuckwall extends at an angle less than said angle of said upper wall portion relative to said center axis.
12. A shell as defined in claim 7 wherein said angle of said inner wall of said countersink is inclined at an angle between an angle of said inclined lower wall portion of said chuckwall and said angle of said inclined upper wall portion of chuckwall.
13. A shell as defined in claim 7 wherein said chuckwall connects with said inner wall of said crown at a first junction and connects with said outer wall of said countersink at a second junction, and the axial distance between said first and second junctions is substantially greater than said width of said countersink.
14. A sheet metal can shell having a vertical center axis and a curled peripheral crown adapted to be double-seamed to an end portion of a formed sheet metal can body, said shell comprising a circular center panel connected by a curved panel wall to an inner wall of a countersink having a U-shaped cross-section, a generally frusto-conical chuckwall including an upper wall portion extending at an angle greater than 16° relative to said center axis and having an inclined lower wall portion connected to an outer wall of said countersink at a first junction, said crown having an inner wall connected to said upper wall portion of said chuckwall at a second junction, said countersink having a radius of curvature substantially smaller than a radius of curvature of said curved panel wall, said first junction being spaced below the level of said center panel, and the axial distance from said center panel to the bottom of said countersink being less than the axial distance from said center panel to the top of said crown.
15. A shell as defined in claim 14 wherein the difference in diameters between said inner wall of said crown and said outer wall of said countersink is greater than said width of said countersink.
16. A shell as defined in claim 14 wherein said upper wall portion of said chuckwall extends at an angle of at least 25° relative to said center axis.
