PROCEDE POUR LA FERMETURE HERMETIQUE D'UN RECIPIENT DE VERRE, A L'AIDE D'UNE MEMBRANE MINCE ET RECIPIENT AINSI OBTENU

摘要

This invention relates to a method of sealing a container mouth, and especially the mouth of a glass container, and the glass container so sealed. The method involves oxidizing the container rim portion, applying a first annular thin coating of an organo-functional silane compound and then a second annular thin coating of an ethylene acrylic acid copolymer over the first coating on the rim portion. A thin imperforate membrane such as aluminum foil having a thermoplastic sealing material such as Surlyn copolymer over its sealing surface is sealed to the container rim portion with heat and pressure.
