In a manufacturing method of a liquid containing container, a capper has a container holding portion configured to be displaced at a constant first velocity in the circumferential direction of a first central axis, the method including: a liquid blow molding step of molding a preform disposed in a cavity of a mold into a container body having a barrel containing a liquid; an intermediate conveying step of, after the mold is opened, gradually accelerating the container body to a third velocity and delivering the container body to a carrier of a rotary conveying machine by an intermediate conveying device; a rotary conveying step of conveying the container body and delivering the container body to the container holding portion by the carrier of the rotary conveying machine; and a capping step of attaching a cap while the container body is conveyed by the container holding portion.

A method of forming and filling a container. The method includes the steps of placing a preform in fluidic communication with an outlet of an injection device of a forming station and forming a container by expanding the preform during a forming step, wherein a forming liquid is injected into the preform through the outlet to expand the preform into the container. The forming liquid is a cleanable liquid. The method further includes a step of transferring the formed container to a concentrate filling station, separate from the forming station and a step of filling the concentrated liquid in the container already containing the cleanable liquid. The step of filling the concentrated liquid is performed in the concentrate filling station.

A piston device having an inlet through which the piston device can receive liquid and an outlet through which the piston device can inject pressurize liquid. A main body (28) of the piston device defines an inner chamber and an upstream duct placing the inner chamber in fluidic communication with the inlet. A valve having a valve plate, which is movable along a plate actuation path, between at least an opened position of the plate and a closed position of the plate. The plate actuation path extending at least in part inside the upstream duct.

A liquid blow molding method comprises: a preliminary pressurization step of operating a pressurization supply source (30) in a state in which a blow nozzle (23) is closed by a seal body (27), to preliminarily pressurize a liquid (L) between the pressurization supply source (30) and the blow nozzle (23); an operating condition setting step of setting an operating condition of the pressurization supply source (30) based on data obtained as a result of the preliminary pressurization step; and a blow molding step of operating the pressurization supply source (30) under the operating condition set in the operating condition setting step in a state in which the blow nozzle (23) is opened, to liquid blow mold a preform (2) into a container of a predetermined shape.

An apparatus for the fabrication of a container, comprising a mold defining the form of said container and container and configured to accommodate a substantially tubular preform, an injection head configured to interface with the preform and establish fluid communication with a cavity thereof; an injection valve configured to selectively permit fluid communication through said injection head, and a stretching rod slideably disposed within the injection head; said apparatus further comprising a displacement plunger being disposed coaxially about and mobile relative to said stretching rod between a retracted position substantially within the injection head and an extended position wherein said displacement plunger projects at least partially from said injection head.

A method and forming station for simultaneously forming and filling a container by injecting a pressurized liquid into a preform. The forming station includes a mold having a molding cavity and an injection nozzle coupled to a pressurized liquid source. The injection nozzle includes a nozzle body and an outlet, the nozzle body defining an injection axis and the outlet being arranged to inject a pressurized liquid from the pressurized liquid source along the injection axis into the preform. The injection nozzle further includes a swirl imparting element arranged to impart a swirl flow to the pressurized liquid about the injection axis, through the outlet and into the preform whereby the preform is formed into the container filled with the pressurized liquid.

An apparatus for forming a container from a preform and delivering a predetermined volume of a liquid end product, formed by the addition of first and second liquid products, into the container. The apparatus includes a heating oven to heat the preform, a mold defining a cavity in the shape of the container, a stretch member coupled to an actuator to stretch the preform in the mold, an injection head configured to inject the second liquid product through the mouth of the preform so as to cause expansion of the preform within the mold thereby obtaining the container, and a preform filler to at least partially fill the preform with the first liquid prior to injecting of the second liquid product and before expanding of the preform into the container.

A liquid blow molding device for liquid blow molding a resin preform into a container having a predetermined shape. The liquid blow molding device includes a mold in which the preform is disposed; a stretch rod that axially stretches the preform disposed in the mold (; and a pressurized liquid supply that supplies a pressurized liquid to the preform. The liquid blow molding device operates such that the amount of the liquid supplied from the pressurized liquid supply to the inside of the preform before completing the stretching of the preform by the stretch rod (22) is 50% or less of the amount of the liquid to be filled in the container after the completion of the liquid blow molding.

A method, system, and preform for liquid forming of the preform into a final-shaped container using the liquid to be contained in the final-shaped container. The preform undergoes a stretching step to a size less than the size of a base of the final-shaped container, before being relocated and stretched to the final shape by the liquid. A stretch rod sealably connects with an interior surface of the preform to partially isolate a gate portion of the preform. The isolation is effected by a portion of the inner surface of the preform extending inwardly, or by a deformable member on the stretch rod which can selectively extend outwardly to contact the interior surface of the preform. The stretch rod includes a selectively heatable tip to heat the gate portion of the preform. The gate portion of the preform includes inner, outer, and core layers which comprise a material configured to affect the thermal properties of the gate portion.

A liquid-containing container manufacturing method includes: an air discharge step of discharging air inside a preform, by opening a preliminary supply path by an opening-closing body in a state in which a seal body is at a closed position to supply a liquid into the preform; and a liquid blow molding step of molding the preform into a liquid-containing container, by moving the seal body from the closed position to a open position to supply the liquid pressurized into the preform through a seat part.
