Abstract:
Provided is a method for manufacturing a glass container with which a glass container having a distinctively shaped inner space and excellent aesthetic appearance can be manufactured in good yield. The method for manufacturing a glass container includes steps (A) to (E). (A) A step of introducing a gob into a mold through a funnel. (B) A step of blowing air into the mold through the funnel, bringing a plunger disposed on a side opposite the side to which the funnel is fitted in contact with the gob, separating the plunger from the gob, and forming a recess on the surface of the gob. (C) A step of removing the funnel from the mold and fitting a baffle to the mold. (D) A step of blowing air from the plunger, and forming an inner space inside the gob with the recess as a starting point while simultaneously forming an outer shape by pressing the outer side of the gob to a molding surface of the mold to obtain a glass container of the final shape. (E) A step of transferring the glass container of the final shape to a cooling mold and cooling the same.
