摘要 |
To provide a vial with low alkali elution and a method for producing the same by removing a deteriorated region caused by processing on an internal surface of a vial. A vial with reduced alkali elution and a method for producing the same by forming vials from borosilicate glass tubes comprises a first step of forming a borosilicate glass tube into a cup-shaped body by formation of a bottom of a vial, and a second step of forming the cup-shaped body into the vial by formation of a mouth of the cup-shaped body. Further provided is a vial with reduced alkali elution and a method for producing the same by forming vials from borosilicate glass tubes, which comprises a first step of forming a borosilicate glass tube into a cup-shaped body to form a bottom of a vial; a second step of fire-blasting an internal surface of said cup-shaped body by a certain length from the bottom toward an opening of said cup-shaped body with flames to remove a deteriorated region caused by processing; and a third step of forming a mouth of said cup-shaped body to complete a vial with reduced alkali elution. |
