Abstract
A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source; and a molding step of liquid blow molding the preform by simultaneously supplying, to the preform, the first liquid pressurized to a predetermined pressure by the first pressurizing source and the second liquid pressurized to a predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source.
Claims3
A liquid blow molding method for molding bottomed tubular-shaped preforms into liquid-containing containers configured to hold a content liquid, the liquid blow molding method comprising:
- a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source, the first liquid and the second liquid being immiscible;
- and
- a molding step of liquid blow molding a first preform by simultaneously supplying, to the first preform, the first liquid pressurized to a first predetermined pressure by the first pressurizing source and the second liquid pressurized to a second predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source, the molding step resulting in a first container being formed from the first preform.
