Abstract
A process for producing an easily openable closure including the steps of producing a closure body by subjecting a shell formed from a metal blank to panel formation, score formation for defining a portion to be opened, bead formation while the shell is intermittently moved for producing a tab, placing a bonding surface of the closure body opposite to a bonding surface of the tab, and bonding the bonding surface of the tab to the bonding surface of the closure body with an adhesive while the closure body and the tab are continuously moved.
