There are provided a one-press manufacturing method for a glass container that can form uneven shapes on an inner peripheral surface of a glass container and a glass container that is obtained by the one-press manufacturing method. The one-press manufacturing method for a glass container includes the following steps (A) to (E); (A) a step of putting a gob in a pressing mold and then inserting a plunger, which includes an unevenness forming member provided so as to be capable of being received in the plunger, into the gob while the unevenness forming member is received in the plunger, (B) a step of forming a glass container having a finished shape, which includes an uneven shape on an inner peripheral surface thereof, by pressing the unevenness forming member against the surface of the gob, which comes into contact with the unevenness forming member, to the outside from the inside of the plunger, (C) a step of receiving the unevenness forming member in the plunger, (D) a step of extracting the plunger, in which the unevenness forming member is received, from the glass container having a finished shape that includes the uneven shape on the inner peripheral surface thereof, and (E) a step of transporting the glass container having a finished shape, which includes the uneven shape on the inner peripheral surface thereof, to a cooling mold and cooling the glass container having a finished shape.

A blank mould base pressing system (9) for forming a burr-free mouth entry for a glass container to be produced, which blank mould base pressing system comprises a piston (9.1) which is operated by charging with gas pressure, preferably with compressed air (18), and a pressing element (10) having a pressing-element profile (10.3), wherein the piston (9.1), when it is charged with gas pressure on one side, brings the blank mould base pressing system (9) into a pressing position in relation to a glass gob (1) which is in a blank mould (2) and is to be moulded and, on contact of the pressing-element profile (10.3) with the glass gob (1), forms a base for the glass container to be produced, wherein the blank mould base pressing system (9) has a means for controlling or regulating the stroke of the piston (9.1), wherein said stroke of the piston (9.1) serves to compensate for mass fluctuations of the glass gob (1), and a method for producing a parison (1.1) by means of the aforementioned blank mould base pressing system (9), wherein the blank mould base pressing system (9) has an internal cooling device for cooling by means of a cooling medium, and a method for producing a parison (1.1) by means of the blank mould base pressing system (9) according to the invention.

A method for producing a glass container by: a) providing a forming vessel, and b) providing a forming die comprising an outer surface, c) placing the forming die in the forming vessel, in a forming position, in which a receiving space is defined between the inner surface of the forming vessel and the outer surface of the forming die, a deformable glass gob extending partially into the receiving space, d) cooling the deformed glass gob while keeping the glass gob in the forming position in the forming vessel and the forming die, and then e) retracting the forming die.

There are provided a glass container that includes mouth portions formed at both end portions thereof facing each other and a manufacturing method of the glass container. Since the glass container is integrally molded by a one-press manufacturing method, the glass container may be more easily manufactured and the mechanical strength of the glass container may be improved in comparison with a case in which portions including mouth portions are separately manufactured and then are integrated with each other. Further, since the glass container is obtained by a one-press manufacturing method, the glass container is thick and has a high-class feeling. A glass container, which is integrally molded by a one-press manufacturing method, includes a first mouth portion and a second mouth portion that are formed at both end portions of the glass container facing each other.
