Abstract:
1. An apparatus for thermally strengthening glass containers each including a neck after they are formed in an I.S. machine, comprising: a tempering Lehr that reheats the glass containers to increase their temperature to a temperature that is sufficiently high to obtain adequate compressive stresses in the glass containers but not so high that the glass containers may become deformed; a cooling station that simultaneously cools the outer and inner surfaces of glass containers in the cooling station rapidly so that all of the stresses in the glass container are locked in, the cooling station comprising: wherein the cooling shroud comprises: a hollow open-topped cylindrical shroud body having an upper end and a lower end, the upper and lower ends of the shroud body each defined by a rim, each of the rims defined by a single continuous surface extending 360° around the entire circumference of the rim; a first plurality of bores extending from the outer surface of the cylindrical shroud body to the inner surface of the cylindrical shroud body that are arranged and configured to direct cooling air supplied to the cylindrical shroud body onto the outside of the neck and finish of the glass container located in the cooling station; and a second plurality of bores extending from the outer surface of the cylindrical shroud body to the inner surface of the cylindrical shroud body that are arranged and configured to direct cooling air supplied to the cylindrical shroud body onto the outside of the body of the glass container located in the cooling station.
