Bottle crown with opener assembly

摘要

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.

主权项

1. A frangible reduced gauge crown for a container opening, the crown comprising:
a top portion having a recessed attachment portion, wherein the recessed attachment portion corrugates the top portion; an annular skirt descending from the top portion and terminating at a bottom annular edge; an opener assembly attached to the top portion at the attachment portion; a frangible scoring arrangement comprising frangible scoring lines formed such that at least one of the frangible scoring lines comprises connections of opposing rounded edges when viewed in cross-section such that the at least one scoring line produces a non-sharp edge on both sides of the at least one scoring line upon breaking, the frangible scoring arrangement further comprising:
a first scoring line extending in a continuous radial direction from the attachment portion to the bottom annular edge of the skirt;a curvilinear second scoring line comprising:
an upper radial segment extending in a continuous radial direction from the attachment portion of the top portion to the annular sidewall of the skirt; anda 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; andan arcuate third scoring line connecting a first end of the first scoring line to a first end of the second scoring line within the recessed attachment portion.
