Abstract

A fabricating method for a quartz vial having a body for containing a substance, a bottom closing a lower end of the body, a cylindrical neck disposed above the body, and a cylindrical mouth disposed above the neck and having an outer diameter larger than that of the neck includes the steps of forming an outer peripheral surface of the neck by shaving, and joining by thermal fusion, to the neck, the body that is separately fabricated. Thus, quartz vials having a predetermined shape can be mass-fabricated.

Claims (5)

1. A fabricating method for a quartz vial having a body for containing a substance and a cylindrical neck disposed above the body comprising the steps of:

forming an outer peripheral surface of the neck by grinding or polishing a quartz glass member; and

forming the body by hot working a portion of the quartz glass member adjacent to the neck in order to increase an inner diameter, an outer diameter and a length of the body, wherein:

the neck and the body are formed integrally from a single quartz glass member, and

the hot working is a process in which the portion of the quartz glass member adjacent to the neck is thermally softened or melted and then the portion of the quartz glass member adjacent to the neck is deformed.
