摘要： The present invention relates to an improved opening end closure which is adapted for interconnection to a beverage container to prevent premature rupturing and detachment of the tear panel from the center panel. More specifically, the present invention includes an improved cent bead, an enlarged score origination loop, and a pull tab with a cut-out portion with one leg longer than the other leg for selectively orienting the direction of force created on the tear panel away from the hinge portion of the tear panel.
