To provide a method for opening, without labor, a glass plug that is fitted into an opening of a glass container body in a ground state.SOLUTION: A method for opening a glass plug 15 that is fitted into an opening 14a of a glass container body 14 in a ground state, and includes: a glass plug holding step of holding the glass plug 15 with a first holding structure 2; a container body holding step of holding the container body 14 with a second holding structure 3, the step being performed before or after the glass plug holding step; and a first glass plug opening step of pulling out to open the glass plug 15 from the container body 14. In the method for opening a ground glass plug, the first glass plug opening step includes performing an operation to pull out the glass plug 15 in the direction of its central axis with the first holding structure 2, and performing an operation to apply a torque with a desired value or less to the glass plug 15 or the container body 14 in the normal or reverse direction with the central axis 15a of the glass plug 15 as a reference axis.SELECTED DRAWING: Figure 1 【課題】ガラス製の容器体の開口にすり合わせた状態で嵌設されるガラス栓を、人手によらず開栓する方法を提供する。【解決手段】ガラス製の容器体１４の開口１４ａにすり合わせた状態で嵌設されるガラス栓１５の開栓方法であって、第１の保持構造２によりガラス栓１５を保持するガラス栓保持工程と、このガラス栓保持工程の前又は後に行われ、第２の保持構造３により容器体１４を保持する容器体保持工程と、容器体１４からガラス栓１５を引き抜いて開栓する第１のガラス栓開栓工程と、を備え、この第１のガラス栓開栓工程は、第１の保持構造２によりガラス栓１５をその中心軸方向に引き抜く動作を行うと同時に、ガラス栓１５又は容器体１４をガラス栓１５の中心軸１５ａを基軸に正逆いずれかの方向に所望の値以下のトルクを作用させる動作を行う、ことを特徴とするすり合わせガラス栓の開栓方法による。【選択図】図１
