Method and apparatus for forming a mouth in a glass container

摘要

Satisfactory molding of a spout in the upper inclined opening edge of a glass container is effected by heating the spout molded portion of the upper opening edge to soften it, premolding the heated softened portion by raising it from the inside of the glass container by the premolding member of a spout premolding device, and finish-molding it by a spout molding device. The spout molding device supports the molding device above a glass container setting position for vertical and horizontal movements, and outwardly substantially horizontally moves this molding member, which is put in the glass container, so as to outwardly push and deform the upper opening edge of the glass container in such a manner as to mold a spout. The path of movement of the molding member is controlled by a fixed cam to finish the spout into a desired shape.
