Abstract
The present invention provides a beverage container lid which can be attached to a beverage container by a skirt extending about the periphery of the lid. In the body of the lid there is defined by a score line a tear tab with a blunt nose portion. The score line extends along opposite lateral sides to a termination site at opposite sides of a hinge situated in an internal area of the lid body. The hinge retains the tear tab as an integral part with the container line while the tab is controlled as to severing from the remaining part of the lid body by the score lines through operation of a pull ring. The pull ring is hinged to the tear tab generally opposite the hinge between the tab and the lid body so that the ring can be used to readily fracture the tear tab about the score line. The ring is used in conjuction with clips for holding and maintaining the tear tab in an opened as well as a closed position. The clips for engaging with the pull ring to hold the tab is closed position are uniquely situated in relation to the hinge connection between the pull ring and the tear tab so that the tear tab can assume a closed position from its original site with good fluid tight integrity.
