NECK RING AND METHOD OF MAKING FOR A GLASS CONTAINER FORMING MACHINE |
摘要 |
A neck ring for molding a glass container neck finish that includes at least one closure attachment feature. The neck ring includes two semi-annular bi-metal neck ring sections (12, 14), each consisting essentially of a neck ring insert (20, 22) of wear- resistant metal construction and a neck ring body (16, 18) of heat-conductive metal construction different from said wear-resistant metal construction and formed around said neck ring insert so as to embed it in said neck ring body. Each of said neck ring halves has a glass-contacting cavity face that includes a first surface portion (30, 32) formed by said inserts for molding the at least one closure attachment feature on the neck finish and a second surface portion (34, 36) formed by said bodies for molding portions of the neck finish excluding the at least one closure attachment feature. |
