- 1. A method for manufacturing an easy open can end, said method comprising the steps of:
- (a) providing a can end blank having a substantially planar portion;
- (b) forming a retained tear strip in said substantially planar portion;
- (c) providing a rivet having a base connected to said can end blank, said rivet being connected in an orientation generally perpendicular to said substantially planar portion; and
- (d) modifying the orientation of said rivet with respect to said can end blank such that said rivet is disposed at a predetermined non-perpendicular angle with respect to said substantially planar portion and tilted away from a major portion of said retained tear strip.
- 2. The method of claim 1 wherein the orientation modifying step includes forming a step in said can end blank adjacent the connected base of said rivet.
- 3. The method of claim 1, further comprising the step of connecting a pull tab to said rivet prior to modifying the orientation of said rivet.
- 4. The method of claim 3 wherein said pull tab includes an opening formed therethrough, and wherein a step is formed in said can end blank adjacent the connected base of said rivet by containing said can end blank with a forming punch extending through said opening.
- 5. The method of claim 1 wherein said predetermined angle of said rivet with respect to said substantially planar portion is in a range of between approximately 7.degree. and approximately 13.degree..
- 6. The method of claim 1 wherein said predetermined angle of said rivet with respect to said substantially planar portion is approximately 10.degree..
- 7. The method of claim 1 wherein said retained tear strip is formed after modifying the orientation of said rivet.
