A machine is for the manufacture of a hollow glass article that includes at least one thin side wall. The machine includes at least one molten glass parison distributor, a blank mold including a cavity designed to successively receive at least one parison of molten glass, and components that form a blank of the article in the blank mold, transfer the blank into a cavity of the finishing mold, and form the article in the finishing mold. The cavity of the finishing mold includes at least one side part provided with a concave cavity to form, on the side wall of the article, a convex bulge directed towards the exterior of the article. The machine further includes a component that removes the bulge to give the side wall of the article a substantially constant thickness.

A blow head mounting arrangement for use to facilitate installation and removal of a blow head from a blow head mounting member. The blow head has a first engagement member for removable engagement with a second engagement member to removably attach the blow head to the blow head mounting member. Once engaged, the blow head is retained on the blow head mounting member by rotating the blow head into a locked position in which it is retained until it is rotated in the opposite direction by a locking mechanism.

The present invention relates to an apparatus for blow-molding a glass bottle, and more particularly, to an apparatus for blow-molding a glass bottle in which molding air is injected into a pair of mold bodies such that molten glass accommodated in the mold bodies is formed into a glass bottle and a groove is formed at the center of the inner side of the bottom surface of the glass bottle. The apparatus for blow-molding a glass bottle of the present invention uses a blow mold (10) configured to include: a pair of mold bodies (11) forming a tubular body; a base mold (12) which molds the bottom surface of the glass bottle; and a blowing head (13) which are arranged in the upper portions of the mold bodies (11) and into which molding air is injected such that the glass bottle is expanded after primary molding and closely contacts the inner walls of the mold bodies (11) and the base mold (12). A groove molder (20) is provided on the inner circumferential edge portion of the blowing head (13) such that a groove portion (15) can be molded on the inner side of the bottom surface of the glass bottle (14).

The invention relates to a process for manufacturing a hollow glass article comprising at least one thin side wall (42), in which process: at least one parison of molten glass is introduced into a blank mold, a blank of the article is formed in the blank mold from said parison, the blank of the article is transferred into a finishing mold, and the article is formed in the finishing mold. During forming of the article, excess glass is directed towards the exterior of the side wall of the article to form a convex bulge (43) and the bulge is removed to give the side wall of the article a substantially constant thickness. The invention also relates to a corresponding machine and product.

The invention provides a method of making a vessel having a sculptural interior, comprising attaching a textile core to the air inlet port of an I.S. machine, inserting a gob of molten glass into a mold to surround the textile core, applying compressed air to press the molten glass around the textile core, applying compressed air to inflate the textile core creating the bottle, allowing the bottle to cool sufficiently to withdraw the core from the bottle, and withdrawing the textile core from the bottle.

A method of providing glass from a glass melting furnace to at least one mold, including providing an uninterrupted glass communication path from an outlet of the glass melting furnace to the at least one mold, and pressurizing the path at a location downstream of the outlet to move molten glass into the at least one mold. A related system, apparatus, and molding equipment are also disclosed.

Various embodiments of a glass blowing method, glass blowing apparatus, and blown glass product are described having a number of innovative features. In one embodiment, the glass blowing method includes positioning molten glass on the end of a blow pipe, positioning the molten glass in a metal framework, and inflating the molten glass with the blow pipe to expand the molten glass through openings in the metal framework. In another embodiment, the glass blowing apparatus includes a blow pipe and a metal framework structured to be coupled to a head of the blow pipe. In another embodiment, the blown glass product includes bubble chambers having an elongated shape with rounded ends positioned opposite tapered ends where the tapered ends converge at an area on one side of the blown glass product.
