Bottle cap and method therefor

Abstract

A closure assembly includes an inner cap with threading along an inner surface. A threading profile extends along an outer surface of an inner cap sidewall. An outer cap is coupled with the inner cap. The outer cap includes an outer cap sidewall extending along at least a portion of the inner cap sidewall, and the outer cap sidewall is substantially cylindrical and uniformly smooth along at least an exterior face. The outer cap sidewall is sized and shaped to conceal the threading profile. An annular rim of the outer cap extends from an open end of the outer cap, and the annular rim is inwardly bent toward the inner cap. In another example, the annular rim extends over the inner cap sidewall and couples the outer cap with the inner cap with an interference fit.

       11 . A closure assembly comprising: 
 an inner cap with threading along an inner surface and a threading profile along an outer surface of an inner cap sidewall;    an outer cap having an outer cap sidewall extending along at least a portion of the inner cap sidewall, wherein the outer cap sidewall is uniformly smooth along at least an exterior face, and an interior face of the outer cap sidewall is sized and shaped to slidably couple over the threaded profile parallel to an inner cap vertical axis; and    wherein an annular rim of the outer cap extends from an open end of the outer cap sidewall, and the annular rim is inwardly bent over at least a portion of the inner cap sidewall, and the annular rim is engaged against the inner cap sidewall.    
   
   
       12 . The closure assembly of  claim 11 , wherein the outer cap sidewall is substantially cylindrical and uniformly smooth along an interior face.  
   
   
       13 . The closure assembly of  claim 11 , wherein an inner cap lid is adhered to an outer cap lid.  
   
   
       14 . The closure assembly of  claim 11 , wherein the outer cap includes embossing along an outer cap lid and the inner cap is free of the embossing.  
   
   
       15 . The closure assembly of  claim 11 , further comprising a liner engaged against an inner cap lid, and the inner cap sidewall extends around the liner.  
   
   
       16 . The closure assembly of  claim 15 , wherein the inner cap sidewall grasps the liner.  
   
   
       17 . A closure assembly comprising: 
 a cap with threading along an inner surface and a threading profile along an outer surface of a cap sidewall, wherein the cap is substantially smooth at the juncture between a cap lid and the cap sidewall;    a blunt annular rim of the cap extending from an open end of the cap sidewall, wherein the blunt annular rim is outwardly bent away from at least a portion of the cap sidewall, and the blunt annular rim is free of curling toward the cap sidewall.    
   
   
       18 . The closure assembly of  claim 17 , further comprising a liner engaged against the cap lid, and the cap sidewall extends around the liner.  
   
   
       19 . The closure assembly of  claim 18 , wherein the cap sidewall grasps the liner.  
   
   
       20 . The closure assembly of  claim 17 , wherein the closure assembly is coupled with a container including a neck ring substantially adjacent to the blunt annular rim, and at least a portion of a blunt annular rim profile is substantially flush with a neck ring profile.  
   
   
       21 . The closure assembly of  claim 20 , further comprising a wrap extending between the closure assembly and the container, wherein the wrap extends around at least a portion of the closure assembly and around at least a portion of the container, and the at least the portion of the blunt annular rim profile and the neck ring profile are visible through the wrap and substantially flush.  
   
   
       22 . A method comprising: 
 forming an inner cap, wherein the inner cap includes threading along an inner surface and a threading profile along an outer surface of an inner cap sidewall;    forming an outer cap, wherein the outer cap has an outer cap sidewall, and the outer cap sidewall is substantially cylindrical and uniformly smooth along at least an exterior face;    coupling the outer cap with the inner cap;    concealing at least the threading profile; and    bending an annular rim toward the inner cap, wherein the annular rim extends from an open end of the outer cap.
