A lever type easy pull crown cap. The lever type easy pull crown cap has a body with a boss extending from a central portion that transitions into a rim with an edge. A pull-ring is fastened to the crown body without piercing the body. An inner surface of the body includes a score line extending from the edge along the rim and across the central portion towards the boss and returns outward across the central portion after travelling around the boss to terminate in a tail segment. The tail segment extends along a portion of the rim without reaching the edge. Pulling upward on the pull-ring fractures the body along the score line and separates a tear strip portion from the body, breaking the seal between the lever type easy pull crown cap and the bottle.
