- This invention relates to the construction or forming of a sheet metal or aluminum can shell and can end having a peripheral rim or crown which is double-seamed to the upper edge portion of a sheet metal or aluminum can body.
- a can end is formed from a drawn sheet metal can shell, for example, a shell produced by tooling as disclosed in U.S. Patent No. 5,857,374 which issued to applicant.
- the formed can shell includes a circular center panel which extends to a panel wall which extends to or also forms the inner wall of a reinforcing rib or countersink having a U-shaped cross-sectional configuration.
- the countersink is connected by a frusto-conical chuckwall to an annular crown which is formed with a peripheral curl.
- the center panel of the shell is commonly provided with an E-Z open tab, and after the can body is filled with a beverage, the peripherally curled crown of the shell is double-seamed to the upper end portion of the can body.
- the present invention is directed to an improved sheet metal shell and can end and a method of forming the can end which provides the desirable features and advantages mentioned above, including a significant reduction in the blank diameter for forming a can shell and a significant increase in strength/weight ratio of the resulting can end.
- a can shell and can end formed in accordance with the invention not only increases the buckle strength of the can end but also minimizes the changes or modifications in the existing tooling for adding E-Z open tabs to the can shells and for double-seaming the can shells to the can bodies.
- the can shell and can end are formed with an overall height between the crown and the countersink of less than .240 inch and preferably less than .230 inch
- the countersink has a generally cylindrical outer wall and an inner wall connected to a curved panel wall.
- a generally frusto-conical chuckwall extends from the outer wall of the countersink to the inner wall of the crown and has an upper wall portion extending at an angle of at least 16° relative to the center axis of the shell, and preferably between 25° and 30°.
- the countersink may have a generally flat bottom wall which connects with the countersink outer wall with a small radius substantially less than the radial width of the bottom wall, and the inside width of the countersink at its bottom is less than the radius of the panel wall.
- a can shell and can end have some of the above structure and with the junction of a lower wall portion of the chuckwall and the outer countersink wall being substantially below the center panel.
- the lower wall portion of the countersink extends at an angle less than 16° relative to the center axis and is connected to the upper wall portion of the countersink by a short generally vertical riser portion and sharp radii, forming a kick.
- the countersink has a radius of curvature substantially smaller than the radius of curvature of the curved panel wall, and the inner width of the countersink at the bottom of the countersink is also less than the radius of the panel wall, and preferably less than .030 inch.

- FIG. 8 is an enlarged fragmentary section similar to FIG. 5 and showing the can shell of FIG. 7 double-seamed onto a can body.
- FIG. 1 illustrates a one-piece shell 10 which is formed from a substantially circular blank of sheet metal or aluminum, preferably having a thickness of about .0085 inch and a blank diameter of about 2.705 inches.
- the shell 10 has a center axis 11 and includes a slightly crowned center panel 12 with an annular portion 14 extending to a curved panel wall 16.
- the center panel wall portion 14 and panel wall 16 may be formed by a series of blended curved walls having radii wherein R1 is 1.489 inch, R2 is .321 inch, R3 is .031 inch, and R4 is .055 inch.
- the curved panel wall 16 has a bottom inner diameter D1 of about 1.855 inch.
- the curved panel wall 16 with the radius R4 extends from an inner wall 17 of a reinforcing rib or countersink 18 having a U-shaped cross-sectional configuration and including a flat annular bottom wall 22 and a generally cylindrical outer wall 24 having an inner diameter D2, for example, of about 1.957 inches.
- the flat bottom wall 22 of the countersink 18 is connected to the inner panel wall 16 and the outer countersink wall 24 by curved corner walls 26 each having an inner radius R5 of about .010 inch.
- the radial width W of the flat bottom wall 22 is preferably about .022 inch so that the inner bottom width W1 of the countersink 18 is about .042 inch.
- the outer wall 24 of the countersink 18 connects with a generally frusto-conical chuckwall 32 by a curved wall 34 having a radius R6 of about .054 inch.
- the chuckwall 32 extends at an angle A1 of at least 16° with respect to the center axis 11 or a vertical reference line 36 which is parallel to the center axis 11 of the shell.
- the angle A1 is between 25° and 30° and on the order of 29°.
- the upper end of the chuckwall 32 connects with the bottom of a curved inner wall 38 of a rounded crown 42 having a curled outer wall 44.
- the inner wall 38 of the crown 42 has a radius R7 of about .070 inch, the inner diameter D3 at the bottom of the curved inner wall 38 is about 2.039 inch, and the outer diameter D4 of the curled outer wall 44 is about 2.340 inches.
- the height C of the curled outer wall 44 is within the range of .075 inch and .095 inch and is preferably about .079 inch.
- the depth D from the bottom of the outer curled wall 44 or the junction 46 of the chuckwall 32 and the inner crown wall 38 to the inner surface of the countersink bottom wall 22 is within the range between .108 inch and .148 inch, and preferably about .126 inch.
- FIG. 3 shows the crown 42 of the shell 10 being double-seamed onto an upper peripheral end portion 48 of a sheet metal or aluminum can body 50.
- the double-seaming operation is performed between a rotating double- seaming circular chuck 55 which engages the shell 10 and has an outer surface 58 which may be slightly tapered between an angle of 0° and 10° with respect to the center axis of the chuck 55 and the common center axis 11 of the shell 10.
- the surface 58 has a slight taper of about 4° and is engaged by the inner wall 38 of the crown 42 in response to radially inward movement of a first stage double-seaming roller 60 while the can body 50 and its contents and the shell 10 are rotating or spinning with the chuck 55.
- the chuck 55 also has a frusto-conical surface 62 which mates with and engages the frusto-conical chuckwall 32 of the shell .10, and a downwardly projecting annular lip portion 64 of the chuck 55 extends into the countersink 18 and has a bottom surface 66 (FIG. 5) and a cylindrical outer surface 68 which engage the bottom wall 22 and the outer wall 24 of the countersink 18, respectively.
- FIGS. 4 & 5 illustrates the completion of the double-seaming operation to form a double-seamed crown 70 between the rotating chuck 55 and a second stage double-seaming roller 72 which also moves radially inwardly while the chuck 55, shell 10 and can body 50 are spinning to convert the shell 10 into a can end 75 which is positively attached and sealed to the upper end portion 48 of the can body 50.
- the double-seamed rim or crown 70 has an inner wall 74 which is formed from the inner wall 38 of the shell crown 42 and also has an outer wall 76 formed from the shell crown 42 including the outer curled wall 44.
- the double-seamed crown 70 has a height H2 within the range between .090 inch and .110 inch and preferably about .100 inch.
- the can end 75 has an overall height H1 between the top of the crown 70 and the bottom of the countersink 18 within the range of .170 inch and .240 inch, and preferably about .235 inch. Since the can end 75 has the same cross-sectional configuration as the shell 10 with the exception of the double-seamed crown 70, the same common reference numbers are used in FIGS. 4-6 for the common structure. [0021] As apparent from FIG. 6, the center portion of the center panel 12 defines a plane 80 which substantially intersects the junction 46 of the chuckwall 32 with the inner wall 74 of the double-seamed crown 70.
- FIGS. 7 & 8 show another embodiment or modification of the invention including a can shell (FIG. 7) and a double-seamed can end (FIG. 8). Accordingly, the structural components corresponding to the components described above in connection with FIGS. 1-6, have the same reference numbers but with the addition of prime marks. Thus referring to FIG.
- a can shell 10* has a center axis which is the same as the axis 11 and includes a circular center panel 12' connected to a peripheral curved panel wall 16' which connects with an inclined inner wall 17' of a countersink 18' having a U-shaped cross-sectional configuration.
- the countersink has a generally cylindrical outer wall 24' which extends at an angle less than 10° and connects with a chuckwall having a frusto-conical upper wall portion 32' and a slightly curved lower wall portion 34'.
- the wall portions 32' and 34' are connected by a kick or generally vertical short riser portion 35* having relatively sharp inside and outside radii, for example, on the order of .020 inch.
- the upper chuckwall portion 32' is connected by a curved wall 37' to the inner curved wall 38' of a crown 42' having a curved outer wall 44'.
- the inner wall 38' of the crown 42' connects with the upper chuckwall portion 32' at a junction 46', and the outer wall 24' of the countersink 18' connects with the lower chuckwall portion 34' at a junction 47".
- the vertical height G1 from the bottom of the countersink 18 * to the kick or riser portion 35' is about .086.
- the radius R10 is about .051 inch, and the lower wall portion 34' extends at an angle A3 of about 15°.
- the countersink 18' has a radius R9 of about .009 to .011 inch.
- Other approximate dimensions and angles for the shell 10' shown in FIG. 7 are as follows:
- the particular cross-sectional configuration of the can shell 10' has been found to provide performance results superior to the performance results provided by the can shell 10. 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 width W1 of the countersink at the bottom between the inner wall 17' and the outer wall 24' is less than .040 inch and preferably about .024 inch.
- 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 shell 10' is double-seamed with the upper end portion 48' of a formed can body 50' using tooling substantially the same as described above in connection with FIGS. 3-5 to form a can end 75'.
- a seamer chuck (not shown), similar to the chuck 55, includes a lower portion similar to the portion 64 which projects into the countersink 18' and has surfaces corresponding to the surfaces 58, 62 and 68 of the seamer chuck 55 for engaging the outer countersink wall 24', the chuckwall portion 32', and for forming the inner wall 74' of the double-seamed crown 70'.
- a seamer chuck similar to the chuck 55, includes a lower portion similar to the portion 64 which projects into the countersink 18' and has surfaces corresponding to the surfaces 58, 62 and 68 of the seamer chuck 55 for engaging the outer countersink wall 24', the chuckwall portion 32', and for forming the inner wall 74' of the double-seamed crown 70'.
- the inner wall 74' of the double-seamed crown 70' extends at a slight angle A5 of about 4°, and the overall height H3 of the can end 75' is less than .240 inch and preferably about .235 inch.
- the height H4 of the double-seamed crown 70' is on the order of .100 inch and the height H7 from the top of the crown 70' to the top of the center panel 12 * is greater than the center panel height H5, preferably about .148 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.
