发明名称 PREPARAZIONE DI UN RECIPIENTE DI VETRO PER LA CHIUSURA TERMOPLASTICA
摘要 A method for preparing a glass container, and for sealing a glass mouth of a container and the seal are described. The sealing surface, or finish, of the container is subjected to a hot end treatment after forming and before annealing to enhance adhesion between the container finish and a thermoplastic membrane seal. The container is next annealed and after annealing is subjected to a cold end treatment in which the exterior container surface is coated with a material which enhances the lubricity and increases the abrasion and scratch resistance of the container. The container finish only is then subjected to a brief heat treatment sufficient to remove any lubricity enhancing material from the finish. A membrane comprising a thermoplastic film is pressed onto the container finish and heated causing glass-plastic adhesion and forming a closure.
