摘要:
The present invention relates to a process for the manufacture of a glass container that comprises the steps of: a) providing a first glass element; b) providing a second element made of a material selected from: glass, ceramic, metal and metallic alloy; said first element and said second element, joined together, defining a containment cavity of said glass container; c) depositing a sealing composition comprising at least one glass frit dispersed in at least one dispersing liquid on at least one surface of at least one of said first element and said second element; d) positioning said first element and said second element in contact with each other so that said sealing composition is arranged between said first element and said second element; e) heating said sealing composition so as to melt said glass frit and form a sealing layer between said first element and said second element. The present invention further relates to a glass container, such as, for example, a bottle, a cup or a jar, and related uses.
