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: An object of the present disclosure is to provide coating film-attached glass having a glass substrate, and a coating film provided on at least a part of a surface of the glass substrate. The coating film-attached glass includes a modified layer in a region at a depth of 100 nm from the surface of the glass substrate on the coating film side in the depth direction. The modified layer has a microcrystalline structure at least in part. The coating film is a silicon-free and fluorine-containing diamond-like carbon film or an amorphous fluorine resin film. Another object of the present disclosure is to provide a production method for coating film-attached glass in which a coating film is formed on at least a part of a surface of a glass substrate.

Abstract: [Object] To provide a means manufacturing a medical vial which contains a Type IA borosilicate glass as the raw material and in which the elution amount of silica into a high ionic strength solution decreases to be equal to or less than the silica elution amount in a Type IB borosilicate glass.[Solution] A method for manufacturing a medical vial is a method for manufacturing a medical vial including a fire blast process of applying a flame ejected from a point burner to a deteriorated layer generated on the inner surface of a vial, in which the vial is molded from a glass tube containing a Type IA borosilicate glass as the raw material and the molar ratio of oxides contained in the borosilicate glass satisfies ψ=0.23±0.02 in ψ=[(Na2O+K2O)—Al2O3]/B2O3 and satisfies β=7.5±0.5 in β=B2O3/Al2O3.

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.
