Method for forming a metal container with a carrier ring and resulting container

Abstract

Disclosed is a method for retaining an outsert on a neck. The method includes providing a neck with a sidewall for a metal body. The method further includes forming an outward curl in the metal sidewall. The method further includes sliding a plastic outsert down onto the neck. The plastic outsert has a first inner diameter at a first end that is smaller than a diameter of the neck encompassing the outward curl. The outward curl is configured to flex as the plastic outsert slides down onto the neck to accommodate the first end of the plastic outsert passing over the outward curl. The method further includes retaining the plastic outsert on the neck between a first interference fit at a first interface of the metal sidewall and the plastic outsert and at a second interference fit between a top edge of the plastic outsert and the outward curl.

1 - 13 . (canceled) 
     
     
         14 . A system for a neck of a metal body, the system comprising:
 a metal sidewall having an outward curl formed in a first end, the outward curl having a first portion that extends away from the metal sidewall and a second portion that curls back toward the metal sidewall; and   a plastic outsert retained on the metal sidewall between a first interference fit at a first interface of the metal sidewall and the plastic outsert and at a second interference fit between a top edge at a first end of the plastic outsert and the second portion of the outward curl.   
     
     
         15 . The system of  claim 14 , wherein the outward curl forms a gap between a tip of the outward curl at an end of the second portion and the metal sidewall. 
     
     
         16 . The system of  claim 15 , wherein the gap varies in distance between the tip of the outward curl and the metal sidewall across a thickness of the tip of the outward curl. 
     
     
         17 . The system of  claim 14 , wherein the plastic outsert has a first inner diameter at the first end that is smaller than a diameter of the neck encompassing the outward curl. 
     
     
         18 . The system of  claim 14 , wherein the outward curl has a substantially circular profile. 
     
     
         19 . The system of  claim 14 , wherein the plastic outsert comprises a plastic sidewall with a thread that extends from and wraps around the plastic sidewall, and a distance the outward curl extends from the metal sidewall is substantially equal to a thickness of the plastic sidewall of the plastic outsert. 
     
     
         20 . The system of  claim 14 , wherein the metal sidewall and the plastic outsert form a preform configured to be formed into the neck of the container.
