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.

摘要： By coating an inner surface of a preform, in which at least an inner surface is made of polyester and which has transparency, with a coating layer, which has elongation capacity and water insolubility, the inner surface of the preform is protected against a pressurized liquid by the coating layer when the pressurized liquid is supplied to the preform, and occurrence of cloudiness on an inner surface of a container after molding is prevented even in a case where a liquid having properties of eroding polyester and causing cloudiness on a polyester surface is used as the pressurized liquid during liquid blow molding.

摘要： A delamination container includes an engaging protrusion that is provided in an area extending over at least a ground contact portion and a recess and protrudes from either one of an outer layer body and an inner layer body and engages with the other in an undercutting manner. Further, a preform includes an engaging protrusion that is provided in an area extending from at least a boundary between a bottom and a trunk to just before an axial center of the bottom and protrudes from either one of an outer body and an inner body and engages with the other in an undercutting manner.

摘要： 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 first molding step of liquid blow molding the preform into a halfway shape by supplying, into the preform that has been heated to a predetermined temperature, a first liquid at a predetermined pressure through a nozzle unit; and a second molding step, performed after the first molding step, of liquid blow molding the preform by supplying a second liquid into the preform at a predetermined pressure through the nozzle unit.
