POLYLAYERS GLASS CONTAINER FROM TRANSPARENT GLASS AND AMBER PIGMENTED GLASS AND METHOD FOR MANUFACTURING THE SAME Russian patent published in 2005 - IPC

FIELD: production of glass containers for food products and the like, in particular, polylayers glass container and method for manufacturing such a container, wherein glass layers are produced from chemically incompatible compositions.

SUBSTANCE: method for forming flow of superposed glass involves enclosing inner glass in layer of enclosing glass, with one of said glasses being reduced glass and other of said glasses being oxidized glass, said inner glass and enclosing glass contacting with one another at melting temperature for time interval not in the excess of 50 s. Method for forming of glass container involves steps of forming flow of superposed glass; cutting droplet from said flow followed by charging into form; forming said droplet into polylayers glass container, with glass container formation step lasting for time interval not in the excess of 50 s so that said glass compositions might not chemically react with each other.

EFFECT: improved quality of glass containers and reduced manufacture costs.
