ABSTRACT:
A blank for forming a bottle cap is disclosed, the completed bottle cap having a tear tab cooperating with score lines extending across the top of the cap for manual removal of the cap from a bottle. Two score lines are provided which extend from the tear tab to the opposite side of the blank, the score lines being asymmetrical to facilitate the formation of a tear-off tab. The described arrangements of score lines serve to obtain an easy removal of the cap from a bottle after the tearing operation.
