Abstract: There is provided a means which carries out a fire-blast treating effectively upon removing a deteriorated region caused by processing in a process of producing a glass vessel. In a process of producing a glass vessel by fire-blast treating an internal surface 10 of a preform of the glass vessel with a flame from a burner 30 so as to produce the glass vessel, said fire-blast treating is carried out such that a temperature of an outer surface portion of the preform which portion is opposed to the deteriorated region caused by processing is between 650° C. and 800° C. when the flame is scanned along the internal surface of the preform toward an opening of the preform.

Abstract: To provide a method for manufacturing a medical glass container prevented from breakage and deformation and a fire blasting device.
A method for manufacturing a medical glass container includes a processing process of placing a glass container 10 on the outer peripheral surface of each of a first roller 61 and a second roller 62, which are disposed side by side in such a manner that the axis lines are parallel to each other, so that the axis line of the glass container 10 is parallel to the axis lines of the first roller 61 and the second roller 62 and the entire outer peripheral surface in an inner surface 15 of the glass container 10 corresponding to a region deteriorated by processing is made to abut on the outer peripheral surface of each of the first roller 61 and the second roller 62, and then applying a flame ejected from a point burner 30 to the region deteriorated by processing in the inner surface 15 of the glass container 10 while rotating the glass container 10 by rotating the first roller 61 and the second roller 62 around the axis lines.

Abstract: [Object] To provide a means manufacturing a medical glass container with less generation of a crack.[Solution] A method for manufacturing a medical glass container includes a first process of moving the tip of an ignited point burner 30 from a standby position where a flame 31 does not contact a vial 10 to a position where the tip of the ignited point burner 30 faces an opening 16 in the outside of the vial 10, a second process of inserting the tip of the point burner 30 into an internal space 14 of the vial 10, a third process of applying the flame 31 to an inner surface 15 of the vial 10 while holding the tip of the point burner 30 in the internal space 14, a fourth process of moving the tip of the point burner 30 to the outside from the internal space 14, and a fifth process of moving the tip of the point burner 30 from the position where the tip of the point burner 30 faces the opening 16 to the standby position. At least in the second process and the fourth process, the flame 31 having heating power weaker than the heating power of the flame 31 of the point burner 30 applied to the inner surface of the vial 10 in the third process is ejected from the point burner 30.
