    • 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.
    • 为了提供具有低碱洗脱性的小瓶,以及通过除去由小瓶的内表面上的加工引起的劣化区域来制造该小瓶的方法。 通过从硼硅酸盐玻璃管形成小瓶,具有减少的碱洗脱的小瓶及其制造方法包括:通过形成小瓶的底部将硼硅酸盐玻璃管形成杯状体的第一步骤,以及第二步骤 通过形成杯状体的口部将杯形体形成到小瓶中。 还提供了一种具有减少的碱洗脱的小瓶及其制造方法,该方法由硼硅酸盐玻璃管形成小瓶,其包括将硼硅酸盐玻璃管形成杯状体以形成小瓶的底部的第一步骤; 第二步骤,通过火焰从所述杯状体的底部朝向所述杯状体的开口一定长度对所述杯状体的内表面进行喷射以去除由加工引起的劣化区域; 以及形成所述杯状体的口以完成具有减少的碱洗脱的小瓶的第三步骤。
