1. A method of forming a container closure comprising:
providing a generally planar metal blank having a product side and a customer side;
forming said generally planar metal blank into a container closure body including a limited container opening and an actuation location;
forming a force concentrating construction disposed adjacent said limited container opening;
forming said force concentrating construction to include a force directing score pattern;
forming said actuation location to be a raised button;
forming said force directing score pattern to include a plurality of circular trapezoids disposed about said button; and
forming said plurality of circular trapezoids to be spaced from each other along adjacent radial sides.
 
4. A method of forming a container closure comprising:
providing a generally planar metal blank having a product side and a customer side;
forming said generally planar metal blank into a container closure body including a limited container opening and an actuation location;
forming a force concentrating construction disposed adjacent said limited container opening;
forming said force concentrating construction to include a number of force focusing scores;
forming said actuation location to be a raised button;
forming each said force focusing score to include a first arcuate portion, a generally arcuate nose, and a second arcuate portion, said nose disposed between, and contiguous with, said first arcuate portion and said second arcuate portion,
wherein each said nose disposed adjacent the perimeter of said button; and
forming said force concentrating construction to include a number of anti-fracture scores,
wherein each said anti-fracture score corresponds to one of a portion of an associated force focusing score.
 
8. A method of forming a container closure comprising:
providing a generally planar metal blank having a product side and a customer side;
forming said generally planar metal blank into a container closure body including a limited container opening and an actuation location;
forming a force concentrating construction disposed adjacent said limited container opening;
forming said force concentrating construction to include a number of force focusing scores;
wherein said force concentrating construction includes a force directing score pattern;
forming said actuation location to be a raised button; and
forming said force directing score pattern to include a plurality of circular trapezoids disposed about said button,
wherein said plurality of circular trapezoids includes a first circular trapezoid and a second circular trapezoid, and
wherein said plurality of circular trapezoids are spaced from each other along adjacent radial sides.
