Bottle crown with opener assembly

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.

What is claimed is: 
     
         1 . A frangible crown for a container opening, the crown comprising:
 a top portion having an opener assembly attachment portion;   an annular skirt descending from the top portion and terminating at a bottom annular edge, the annular skirt being free of threads;
 a frangible scoring arrangement comprising a first scoring line extending from the attachment portion to the bottom edge of the skirt, and a second scoring line extending from the attachment portion to the annular sidewall of the skirt, and then extending circumferentially along the annular side wall to an endpoint substantially spaced from the bottom annular edge of the skirt; 
   an underside defining an interior underside space within the skirt;   a liner permanently affixed to the underside, wherein the liner comprises a cross-section profile extending below the bottom annular edge of the annular skirt by a distance greater than a distance measured from the top portion to the bottom annular edge, and wherein an outer surface of the liner comprises an entirely smooth surface free of openings thereby promoting a seal; and   an opener assembly attached to the top portion at the attachment portion.   
     
     
         2 . The crown of  claim 1 , further comprising an arcuate third scoring line connecting a first end of the first scoring line to a first end of the second scoring line within the attachment portion. 
     
     
         3 . The crown of  claim 2 , wherein the arcuate third scoring line is formed at least partially around a rivet comprised within the attachment portion, the rivet configured to attach the opener assembly to the attachment portion. 
     
     
         4 . The crown of  claim 2 , further comprising a fourth scoring line, a first end of the fourth scoring line located proximate to the arcuate third scoring line. 
     
     
         5 . The crown of  claim 1 , wherein the liner extending below the bottom annular edge of the annular skirt comprises a v-shaped cross-section profile. 
     
     
         6 . The crown of  claim 1 , wherein the liner extending below the bottom annular edge of the annular skirt comprises an arcuate cross-section profile. 
     
     
         7 . The crown of  claim 1 , wherein the liner extending below the bottom annular edge of the annular skirt comprises a squared-off cross-section profile. 
     
     
         8 . The crown of  claim 1 , wherein the liner comprises synthetic cork. 
     
     
         9 . The crown of  claim 1 , wherein the opener assembly 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.   
     
     
         10 . The crown of  claim 9 , wherein the top portion comprises a recessed seat corrugating the top portion and having the attachment portion therein, and wherein the recessed seat is sized to at least partially received the opener assembly within the recessed seat. 
     
     
         11 . The crown of  claim 10 , wherein the recessed seat is at a concentric center of the top portion and the attachment portion is off-center from a center of the recessed seat. 
     
     
         12 . The crown of  claim 10 , wherein the recessed seat comprises two concentric recessed areas corrugating the top portion. 
     
     
         13 . A frangible crown for a container opening, the crown comprising:
 a top portion having an opener assembly attachment portion;   an annular skirt descending from the top portion and terminating at a bottom annular edge, the annular skirt being free of threads;   an underside defining an interior underside space within the skirt;   a liner permanently affixed to the underside, wherein the liner comprises a cross-section profile extending below the bottom annular edge of the annular skirt by a distance greater than a distance measured from the top portion to the bottom annular edge, and wherein an outer surface of the liner comprises an entirely smooth surface free of openings thereby promoting a seal;   a frangible scoring arrangement comprising at least first and second scoring lines extending from the attachment portion towards the skirt;   an opener assembly attached to the top portion at the attachment portion;   wherein the top portion comprises a recessed seat corrugating the top portion and having the attachment portion therein, and wherein the recessed seat is sized to at least partially received the opener assembly within the recessed seat; and   wherein the recessed seat is at a concentric center of the top portion and the attachment portion is off-center from a center of the recessed seat.   
     
     
         14 . The crown of  claim 13 , wherein the liner extending below the bottom annular edge of the annular skirt comprises a v-shaped cross-section profile. 
     
     
         15 . The crown of  claim 13 , wherein the liner extending below the bottom annular edge of the annular skirt comprises an arcuate cross-section profile. 
     
     
         16 . The crown of  claim 13 , wherein the liner extending below the bottom annular edge of the annular skirt comprises a squared-off cross-section profile. 
     
     
         17 . The crown of  claim 13 , wherein the liner comprises synthetic cork. 
     
     
         18 . The crown of  claim 13 , wherein the opener assembly 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.   
     
     
         19 . The crown of  claim 13 , wherein the recessed seat comprises two concentric recessed areas corrugating the top portion.
