A closure for bottles is disclosed which includes an internal radius support disk or cylinder for positioning within the bottle mouth to enable the bottle to resist radial inward deformation when subjected to pasteurization or other post-bottling heat treatment. The closure can be formed by coining a conventional aluminum roll-on cap blank using a pressure block having a central land projectable into the mouth of the bottle to form the support disk or cylinder from the top of the cap blank.
In the process of pasteurizing a carbonated beverage contained in a bottle, the bottle consisting essentially of a thermoplastic resin which is deformable when subjected to an elevated temperature equivalent to pasteurization, the bottle being formed to include a finish portion defining the mouth of the bottle, a method of maintaining the configuration of the finish of the bottle during exposure to the elevated temperature, the method comprising the sequential steps of: providing a metal closure having a substantially flat top wall defining a continuous ...
