Abstract:
A method for manufacturing a glass container, comprising the steps of:providing a die having an upper mold, a lower mold, and positioning a burner between said upper mold and said lower mold, said upper mold having a projection formed with dimensions and a configuration substantially identical with those of an inner hollow section of a glass container which has a frame integrally formed on an outer edge thereof and in the form of a finished product, said lower mold having a cavity with dimensions and a configuration substantially identical with outer dimensions and a configuration of said glass container and arranged opposite to said upper mold;supporting a glass substrate on said lower mold while keeping said glass substrate lifted by a predetermined distance from said lower mold;heating said glass substrate to at least a softening temperature of said glass substrate by said burner;heating said upper and lower molds to a temperature lower than a softening point of said glass substrate; andpressing said glass substrate so as to be in the shape of said glass container by moving said upper mold downwardly and pressing said glass substrate between said upper and lower molds.
