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,
