There is provided a one-press method for producing a glass vessel, the method enabling efficient production of even a glass vessel having the maximum thick wall part having a thickness larger than a predetermined value by using a divided type forming mold having a specific parting line. The one-press method for producing a glass vessel, the method including (A) a press step of molding, by one press, a parison having a finish form from the gob by using a forming die including a forming die base part and a mouth die which are each divided into two parts by a predetermined parting line, (B) a transfer step of transferring the parison having a finish form to a cooling mold, and (C) a cooling step of making the parison having a finish form into a glass vessel by blowing off a first cooling air along the inside peripheral surface of the parison having a finish form and supplying a second cooling air that cools the outside peripheral surface of the parison having a finish form, wherein the press step (A) is carried out using a forming die having a parting line positioned at the shoulder part between the mouth ring part and body part of the parison having a finish form.
