Abstract
A tear-off container closure, such as a cap for sealing bottles, has an upper covering panel, a cylindrical cap skirt, a tear-off strip defined by score lines in the covering plate and cap skirt. The strip continues as (a) a tongue protruding outside the cap skirt and (b) a pulling member joined to the tongue of the tear-off strip. The pulling member includes a connecting portion, made of plastic. This connecting portion is joined to the tongue of the tear-off strip to form a joint between tongue and connecting portion which joint is resistant to tensile and torsional stress. The outwardly directed side of the joint is also provided with a protruding spacer, the upper operative surface of which is spaced from the root of the tongue by a distance substantially less than the height of the cap skirt.
