Claims

[Scope of utility model registration request]

A panel portion on which a tear opening score is formed and a pull tab fixed to the center side of the panel portion, and by pulling the pull tab radially outward, the tear opening score portion near the periphery of the panel portion can be removed. In an easy-open can lid that is finally torn open, the panel portion includes an auxiliary score that is close to the tear-open score and has a larger residual score thickness than the tear-open score. An easy-open can lid characterized in that the lid is formed except for the vicinity of the periphery.
