An apparatus for manufacturing strengthened glass containers, and more particularly the construction and operation of a cooling shroud in an apparatus for thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are rapidly thermally strengthened in a cooling station in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers, with the cooling shrouds being used to cool the outer surfaces of the glass containers.

A method of manufacturing of strengthened glass containers, and more particularly a method of thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are subjected to a unique rapid thermal strengthening cooling process in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers.

Post-manufacture glass container thermal strengthening station

An apparatus for manufacturing strengthened glass containers, and more particularly the construction and operation of a bottom cooler in an apparatus for thermally strengthening glass containers in a glass container manufacturing line at a location intermediate the hot end and the cold end. Glass containers formed at an I.S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers are rapidly thermally strengthened in a cooling station in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers, with the bottom coolers being used to cool the bottoms of the glass containers.

A method of manufacturing of strengthened glass containers, and more particularly a method of thermally strengthening glass containers in a glass container manufacturing line while they are on a conveyor intermediate the hot end and the cold end. Glass containers formed at an I. S. machine are conveyed through a special tempering Lehr that heats them uniformly to a high temperature that is short of temperatures at which they may become deformed. Subsequently, the glass containers while being transported on a conveyor are subjected to a unique rapid thermal strengthening cooling process in which the outer and inner surfaces including all areas of the glass containers are simultaneously cooled to a temperature below the Strain Point of the glass used in the glass containers.

An improved and mechanically simplified blow head mechanism for blowing a parison and internally cooling the blown parison is disclosed which may be used with an I.S. machine to blow a parison to form a glass container and then internally cool the blown parison below the annealing point. The blow head mechanism has a cooling tube which supplies final blow and cooling air and which is raised or lowered by raising or lowering the blow head mechanism. The blow head mechanism supports a blow head with a pressurized cylinder which maintains the blow head in a position in engagement with the finish of a parison once initially lowered irrespective of the blow head mechanism being further lowered to lower the cooling tube into the blown parison.
