Bottle crown with opener assembly
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.
1. A frangible crown for a container opening, the crown comprising:
a top portion having an attachment portion;
an annular skirt descending from the top portion and terminating at a bottom annular edge;
an opener assembly attached to the top at the attachment portion;
a frangible scoring arrangement comprising:
a first scoring line extending in a continuous radial direction from the attachment portion to the bottom edge of the skirt; and
a second curvilinear scoring line comprising:
an upper radial segment extending in a continuous radial direction from the attachment portion of the top to the annular sidewall of the skirt, and
a 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.
2. The crown of claim 1 , wherein the opener assembly further comprises
a pull tab ring;
a pull tab attached to the pull tab ring; and
a rivet attached to the pull tab and to the attachment portion of the top.
3. The crown of claim 2 , the opener assembly further comprising a lever under the pull tab.
4. The crown of claim 1 , wherein the top further comprises a center portion and wherein the attachment portion is at the center portion of the top.
5. The crown of claim 1 , wherein the top further comprises a center portion and wherein the attachment portion is off-center from the center portion of the top.
6. The crown of claim 2 , where in the top portion further comprises a recessed seat.
7. The crown of claim 1 , wherein at least one of the scoring lines is tapered to have greater depth near the annular edge of the skirt than near the attachment portion.
8. The crown of claim 1 , comprising a divot on the top portion to facilitate manual crown removal.
9. The crown of claim 1 , further comprising an interior under portion opposite of and defined by the top portion and the skirt; a liner fastened to the under portion.
10. The crown of claim 1 , further comprising a cushion on the pull tab ring.
11. The crown of claim 1 , wherein the top is corrugated.
12. The crown of claim 1 , further comprising a crown thickness gauge in the range of 0.12 mm to 28 mm.
13. The crown of claim 1 , wherein the frangible scoring arrangement defines a frangible portion of the frangible crown, the frangible portion extending outward from the attachment portion to the bottom edge of the skirt, the frangible portion having a curved profile shape in cross-section.
14. The crown of claim 1 , wherein the frangible scoring arrangement defines a frangible portion of the frangible crown, the frangible portion extending outward from the attachment portion to the bottom edge of the skirt, the frangible portion having a square shape in cross-section.
15. The crown of claim 1 , wherein the frangible scoring arrangement defines a frangible portion of the frangible crown, the frangible portion extending outward from the attachment portion to the bottom edge of the skirt, the frangible portion having a V shape in cross-section.
16. The crown of claim 1 , wherein at least one of the scoring lines of the frangible scoring arrangement produces a non-sharp edge upon breaking.
17. The crown of claim 1 , wherein the skirt comprises a plurality of angels.
18. The crown of claim 1 , wherein the skirt comprises no angels.
19. The crown of claim 1 , wherein the first scoring line is curvilinear.
20. A frangible crown for a container opening, the crown comprising:
a top portion having an attachment portion;
an annular skirt descending from the top portion and terminating at a bottom annular edge;
an opener assembly attached to the top at the attachment portion;
a frangible scoring arrangement comprising:
a first curvilinear scoring line extending in a continuous radial direction from the attachment portion to the bottom edge of the skirt; and
a second curvilinear scoring line comprising:
an upper radial segment extending in a continuous radial direction from the attachment portion of the top to the annular sidewall of the skirt, and
a 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.
