Abstract
Break-away closures are formed by an injection molding process with a closure part in interference path with a forming core for interference in use with a counterpart surface of a container neck. The process and apparatus disclosed permits stripping of the formed closure from the core by selectively creating free encircling space about the interference closure part for expansion thereof during stripping. The closure has detent surface molded therein which assists the stripping operation and the process and apparatus provide for the application of stripping forces at spaced locations simultaneously to permit stripping of the closure in part without axial loading thereof.
