ONE-PRESS MANUFACTURING METHOD FOR GLASS CONTAINER AND GLASS CONTAINER

摘要

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.
