<P>PROBLEM TO BE SOLVED: To provide an orifice with a temperature measuring instrument which can reliably perform temperature control of a gob without varying the shape of the gob, and a method for manufacturing a glass bottle. <P>SOLUTION: An extrusion hole 7 of an orifice body 2 is provided with a temperature measuring instrument 3 including a detection ring 10 in which molten glass 61 is allowed to flow and a thermocouple 26 connected thereto. The molten glass 61 is brought into continuous contact with the detection ring 10 without varying the shape of the molten glass 61 extruded from the extrusion hole 7 to measure the surface temperature of the molten glass 61, the shape of a gob 62 is controlled on the basis of the measuring results, and gobs 62 of the same shape are supplied to a glass bottle molding apparatus 55 at all times. <P>COPYRIGHT: (C)2013,JPO&INPIT |
