A liquid blow-molding apparatus in which a liquid circulates between a feed path formed in a support block, when a valve mechanism is in a closed state, and a pressurized liquid feed unit, and pressurized liquid is fed from the feed path through a blow nozzle into a preform when the valve mechanism is in an open state. The feed path has a shape including a flow path body, a dome chamber that is formed in a domed shape and that is continuous with an upper end of the flow path body, a first port that has the same upper end as the dome chamber and which extends horizontally from the dome chamber, and a second port connected to the flow path body.

A blow molding device for blow molding preforms into a predetermined shape. The blow molding device includes a batch-type mold provided with cavities, a heating furnace that heats preforms while the preforms are arranged in series, a transfer machine that simultaneously transfers the preforms as a batch to the cavities of the mold after the preforms are heated and sent out sequentially from the heating furnace, and a pressurized liquid feeder that feeds pressurized liquid to the preforms after the preforms are arranged in all of the cavities of the mold and the mold is closed.

A method for fabricating containers wherein a molding apparatus is provided having a plurality of mold segments, each of which has two substantially opposite faces that form a mold cavity when abutted against an opposite face of an adjacent mold segment. A first mold segment is passed through a manipulation zone at an increased speed to open the mold cavity between the first and second mold segments. After a preform is positioned within the mold cavity, a second mold segment is passed through the manipulation zone at an increased speed to abut a face of the first mold segment against an opposite face of the second mold segment. A volume of a liquid is next injected into the preform, expanding the preform and forming the container. These steps are repeated and a container produced during the previous iteration is removed during an extracting step in an extracting manipulation zone.

A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid containing container. The method includes a nozzle engaging step of engaging a blow nozzle with a mouth of the preform; a molding step of molding the preform into a container of a predetermined shape by supplying a pressurized liquid from a pump into the preform; a suck-back step of sucking back a predetermined volume of liquid out of the container into a supply path; a nozzle closing step of closing the blow nozzle by a sealing body; and a discharge step of discharging a liquid in the supply path by a predetermined volume from a discharge port by operating, after the nozzle closing step, a pump in a positive direction with the discharge port connected to the supply path opened.

A synthetic resin container having a bottle shape including a tube-shaped mouth, a tube-shaped trunk having one end closed by a bottom, and a shoulder through which another end of the trunk is connected to the mouth. The shoulder is inclined at an angle greater than 120 with respect to an axis of the mouth, and the shoulder has a crystal orientation in a machine direction of less than 1.

A method comprising a first injection step, wherein a first predetermined volume of pressurized liquid is injected into the preform, the predetermined volume corresponding to a fraction of the container volume, the first injection step causing an expansion of the preform into a first intermediate container. The method further comprising a second injection step, wherein, once the first predetermined volume of liquid has been injected, the liquid injection speed is reduced and the pressurized liquid is further injected in the first intermediate container until a predetermined switch pressure in the liquid injection circuit is reached, the second injection step causing an expansion of the first intermediate container into a second intermediate container, and a third injection step starting once the predetermined switch pressure is reached, wherein the liquid injection speed is decelerated until the liquid injection is stopped.

A polyester resin for use in a process in which, during an expansion step, an incompressible fluid is injected through an opening of a preform, formed of the polyester resin, to form a container. The polyester resin includes a crystallizable polyester polymer wherein the polyester polymer is comprised of acid moieties and glycol moieties, with at least 85% of the total moles of acid moieties being terephthalate derived from terephthalic acid or its dimethyl ester and at least 85% of the total moles of glycol moieties derived from ethylene glycol. At least 2% of the total moles of acid plus glycol moieties are derived from a primary comonomer with the mole percents of the acid plus glycol moieties totaling 100 mole %.

A blow molding device is provided with a mold in which a preform is disposed, a cylindrical nozzle that is inserted into a mouth part of the preform, a pressurized fluid supply part for supplying a pressurized incompressible fluid to the nozzle, a sealing body that is movable between a closed position that blocks the nozzle and an open position that opens the nozzle, a plurality of suction holes provided on an inner peripheral surface of the nozzle, a vertical hole provided extending along the axial direction of the nozzle for connecting a plurality of suction holes to each other, and a suction pump connected to the vertical hole via a suction path for applying suction force to a plurality of the suction holes for suctioning incompressible fluid adhered to the nozzle.

A method of hydroforming a container from a preform. During the method, an injection nozzle is moved from a retracted position, where the nozzle is spaced away from the neck of the preform, to an intermediate position, where contact is established between a first contact surface of the nozzle and the finish of the preform. The nozzle is then moved from the intermediate position to an injection position, where a second contact surface of the nozzle abuts an abutment surface and the neck is axially compressed. With the nozzle in the injection position, a liquid is injected from the nozzle into the preform causing the preform to expand and form the container.

A method for simultaneously forming and filling a container by injecting a pressurized liquid in a preform. The method includes placing the preform in a mold and injecting the pressurized liquid into the preform such that the liquid expands the preform and urges the wall of the preform against the wall of the molding cavity forming the preform into a container and the container is filled with liquid. A swirl imparting element extends in the injection flow and imparts a swirl flow on the pressurized liquid such that the pressurized liquid applies a centrifugal force on the wall of the preform during forming and filling of the preform, thereby promoting a radial expansion of the preform in radial planes substantially perpendicular to the preform axis.
