Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The liquid blow molding method of claim 1 , further comprising a suck-back step performed after the molding step, the suck-back step including sucking a predetermined amount of the first liquid and the second liquid out of the first container after molding. 3. The liquid blow molding method of claim 2 , further comprising a pre-supply step performed after the suck-back step and before a secondary molding step of a second preform to be molded after the molding step of the first preform, the pre-supply step including supplying, into the second preform at a third predetermined pressure, the first liquid and the second liquid that was sucked out of the first container in the suck-back step.
