摘要： A liquid blow molding apparatus including a support pin disposed in a blow mold. The support pin includes a head and a shaft. The support pin is configured to define a gap between the head and a bottom of the preform in a state where the preform is placed in the blow mold and is also configured to support the bottom of the preform at a time of a molding process and to be displaced downward in accordance with deformation of the preform.

摘要： A liquid blow molding device and a liquid blow molding method are configured to supply pressurized liquid to a preform mounted to a mold to mold the preform into a shape along a cavity of the mold, and includes a blow nozzle fitted into a mouth portion of the preform, a plunger pump configured to supply pressurized liquid to the preform through the blow nozzle and a controller configured to control operation of the plunger pump. The controller controls operation of the plunger pump by position control in which a plunger of the plunger pump is moved from an original position to a predetermined final position with a predetermined operating force.

摘要： A liquid blow-molding method for molding a delamination container from a resin container material. The resin container material includes an outer layer, an inner layer, and an ambient air introduction hole. The delamination container includes an outer layer body and an inner layer body, which is laminated on the inner side of the outer layer body in a manner such that the inner layer body is separatable from the outer layer body. The liquid blow-molding method includes the container molding step of molding the container material into the delamination container by supplying a pressurized liquid into the container material; and the inner layer body separation step of separating the inner layer body from the outer layer body by sucking the liquid out of the delamination container.

摘要： A container production method by liquid blow molding. The method includes a pushing step in which a liquid is collected from a preform at the timing at which the pressure inside of the preform starts rising by pushing of the expanded and deformed preform by a movable mold portion of a blow molding mold so that the rise in the pressure is suppressed or prevented.

摘要： A liquid-blow molding apparatus including a blow-molding mold that houses a preform leaving a mouth that serves as an open end thereof; a blow nozzle that supplies a pressurized liquid into the preform; a partition-wall member that closely surrounds a periphery of an outer-wall surface of the mouth of the preform and defines a mouth-external pressurized space with the outer-wall surface; and pressurized liquid-supply means for supplying a pressurized liquid into the mouth-external pressurized space so that pressure in the mouth-external pressurized space is higher than pressure inside the preform during liquid blow-molding.
