- a crown body comprising;
a top portion;
an annular skirt having an annular side wall descending from the top portion and terminating at a bottom annular edge;
a frangible scoring arrangement comprising;
a curvilinear first score line extending in a first continuous radial direction from the top portion to the bottom annular edge of the skirt;
a plurality of rear score lines to facilitate cracking the frangible crown; and
a curvilinear second score line comprising;
an upper radial segment extending in the first continuous radial direction from the top portion to the annular sidewall of the skirt, anda lower annular segment extending circumferentially along the annular side wall of the skirt from the upper radial segment to an endpoint substantially spaced from the bottom annular edge of the skirt;
an opener assembly attached to an attachment portion of the top portion and configured to break the top portion at one or more of the first and second score lines, the opener assembly comprising;
a non-metal ring pull having a molded connecting portion, anda metal pull tab having a connecting end formed with engaging features,wherein the connecting end of the metal pull tab is secured within the molded connecting portion of the non-metal ring pull using the engaging features extending within the molded connecting portion of the non-metal ring pull; and
an attachment device coupling the metal pull tab to the attachment portion.

Abstract
A crown for a bottle or other container has a top portion and an annular skirt that descends contiguously from the top portion. An opener assembly and an arrangement of frangible scoring lines on the crown allow for ease of opening the bottle or container. Corrugated embodiments provide material strengthening for a reduced gauge crown. Embodiments include entire crowns formed of non-metal materials, metal crowns having non-metal opener assemblies, and metal crowns having opener assemblies that are partially metal and partially non-metal. Unique techniques for attachment of such various opener assemblies are also disclosed.

5. A frangible crown for a container opening, the crown comprising:
-
a top portion; an annular skirt having an annular side wall descending from the top portion and terminating at a bottom annular edge; an opener assembly comprising; a metal pull tab having a connecting end formed with engaging features; and a non-metal ring pull having a connecting portion molded about the engaging features of the metal pull tab, wherein the connecting end of the metal pull tab is secured within the molded connecting portion of the non-metal ring pull using the engaging features extending within the molded connecting portion of the non-metal ring pull, wherein the metal pull tab further having a second end integrally formed with an attachment portion of the annular sidewall such that the second end and the attachment portion of the annular sidewall are formed as a single unitary piece rather than two separate pieces joined together by an attachment means; a recessed portion inwardly formed in the top portion and configured to receive the nonmetal ring pull therein; a frangible scoring arrangement comprising; a curvilinear first score line extending in a first continuous radial direction from the recessed portion along the annular sidewall to the bottom edge of the skirt; and a curvilinear second score line comprising; an upper radial segment extending in the first continuous radial direction from the annular sidewall to an intermediate portion of the skirt, and a lower annular segment extending circumferentially along the intermediate portion of the skirt from the upper radial segment to an endpoint substantially spaced from the bottom annular edge of the skirt, wherein the first score line and the upper radial segment of the second score line define the lateral edges of the pull tab on the annular sidewall. - View Dependent Claims (6, 7, 8, 9, 10)
