Abstract
A pull tab crown for a bottle or other container provides an opener secured to the top of the crown. The crown has an annular skirt with an annular edge. Score lines extend from the opener assembly to the skirt. One of the score lines is curvilinear and terminates at the annular edge. A second score line has a segment that extends from the opener assembly to an endpoint substantially spaced from the bottom annular edge of the skirt.

A method of manufacturing a frangible crown for a container opening, the method comprising:
- forming a top portion of the crown and an attachment portion in the top portion;
- forming an annular skirt descending from the top portion and terminating at a bottom annular edge;
- attaching an opener assembly to the top portion at the attachment portion;
- providing a frangible scoring arrangement by:
- forming a first scoring line extending from the attachment portion to the bottom edge of the skirt;
- and
- forming a curvilinear second scoring line by:
- forming an upper radial segment extending in a continuous radial direction from the attachment portion of the top portion to an annular sidewall of the skirt, and
- forming a lower annular segment extending circumferentially along the annular sidewall of the skirt from the upper radial segment to an endpoint substantially spaced from the bottom annular edge of the skirt.
