    摘要： There is provided a method of manufacturing a glass container that can manufacture a glass container, which includes a bubble formed in a bottom portion and independent of the outside, with high yield by accurately controlling the position and size of the bubble.
    A method of manufacturing a glass container that includes a mouth portion, a body portion, and a bottom portion, includes: a step of molding a glass container, in which a bubble is not yet formed, from molten glass; a step of forming a bubble-forming passage by pulling out a needle-like member after inserting the needle-like member into a bottom portion of the glass container in which a bubble is not yet formed; a step of injecting air from an inlet of the bubble-forming passage to form a reverse teardrop-shaped internal space, which is widened in the bottom portion from the bubble-forming passage as a starting point, in the bottom portion of the glass container in which a bubble is not yet formed, and to obtain a glass container that includes an internal space communicating with the outside; and a step of closing an inlet side of the reverse teardrop-shaped internal space by flow of not yet cured glass, which is caused by the potential heat of the not yet cured glass, to obtain a glass container that includes a bubble formed in the bottom portion and independent of the outside.

    摘要： The bottom plate mechanism has an adaptor plate (10) on which bottom plates of one or more moulds are mounted. The adaptor plate contains passages (14, 20) which connect an inlet (16) thereof to a source of vacuum through a filter (72). In order that the filter may be rapidly changed, the adapter plate is supported by a vertically-extending tubular member (24) which is supported for height adjustment, with a cylindrical projection (12) of the adaptor plate telescopically received within the tubular member. The arrangement is such that the adaptor plate (10) may be lifted away from the tubular member (24) so that the cylindrical projection (12) and filter (72), which is mounted on the cylindrical projection, leave the tubular member.
