Abstract
Official abstract text for this publication.
A method for producing a vial with low alkali elution by removing a deteriorated region caused by processing on an internal surface of a vial is disclosed. The method involves forming vials from borosilicate glass tubes including 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a vial with low alkali elution by forming the vial from a borosilicate glass tube, said method comprising: forming the borosilicate glass tube into a cup-shaped body to form a bottom of the vial as a first step, fire-blasting an internal surface of the cup-shaped body with a flame is carried out as a second step to remove a deteriorated region caused by processing, and then forming a mouth of the vial is carried out as a third step. 2. The method according to claim 1 , wherein said fire-blasting is carried out from the bottom of the cup-shaped body toward an opening of the cup-shaped body by a certain length with the flame. 3. The method according to claim 2 , wherein said flame is a gas-and-oxygen flame produced by a point burner. 4. The method according to claim 2 wherein said fire-blasting is carried out while rotating the vial. 5. The method according to claim 1 , wherein said flame is a gas-and-oxygen flame produced by a point burner. 6. The method according to claim 5 wherein said fire-blasting is carried out while rotating the vial. 7. The method according to claim 1 wherein said fire-blasting is carried out while rotating the vial.
