A liquid forming and filling system for filling a container with a liquid. The liquid forming and filling system having a motor, a gear box operably coupled to the motor configured to receive a driving output from the motor and outputting a gear box driving force, a linear screw operably coupled to the gear box configured to produce linear movement in response to rotational movement from the gear box, a forming cylinder configured to output pressurized liquid for forming and filling the container, the forming cylinder being in an inverted orientation, a top manifold plate and end cap vent valve assembly coupled to the forming cylinder for receiving the pressurize liquid, and a vent valve operably coupled to the top manifold plate and end cap vent valve assembly configured to vent air entrapped within the pressurized liquid.

A container manufacturing method includes: a liquid discharge step in which a predetermined amount of liquid (L) in the container (C) is discharged to the outside by supplying pressurized air from air holes (13) provided in a blow molding mold (11) to a cavity (12) and pushing an outer surface of the container (C) after molding by the air; and a headspace forming step in which a headspace (HS) is formed in the container (C) by separating a filling nozzle (22) from a mouth portion (Ca) of the container (C) in a state in which a predetermined amount of liquid (L) is discharged to the outside.

A method and molding system for hydraulic blow molding of a container from a preform. The method precharges the molding medium within a fill head unit to a precharge pressure. During the injecting of the molding medium into the preform, the method further increases the pressure of the molding medium to a pressure greater than the precharge pressure.

Systems and methods for making a reduced material container are provided that hold a preform adjacent to an open end of the preform, stretch the preform, close a mold about the stretched preform to form a truncated preform, and introduce a pressurized fluid into the truncated preform to expand the truncated preform and form the reduced material container. A stretch rod can be inserted into the preform to mechanically stretching the preform. The mold accepts the preform at a first end thereof, has an open state and a closed state, and the closed state forms a cavity defining an internal surface having a second end located remotely from the first end. A first length is defined by a distance between the first end and the second end, the stretch rod mechanically stretching the preform to a second length, the second length being greater than the first length.

A rotary machine includes a main axis, a plurality of first stations and a plurality of second stations. Each first station rotates around the main axis and applies a first process to a container. Each second station rotates around the main axis and applies a second process to a processed container. The machine also includes an internal exit position, at which each first station is located once the first station has completed the first process and that is arranged to release the processed container. At an internal entry position, each second station is arranged to receive the released processed container. At least one transfer arm is adapted to seize a processed container and move the processed container between a first station located at the internal exit position and a second station located at the internal entry position.

A high-density polyethylene (HDPE) resin configured to be molded into a preform that can be biaxially expanded within a cavity of a container mold by introducing an incompressible fluid under pressure into the preform to stretch the preform to assume a shape of a surrounding mold cavity of the container mold. The HDPE resin has: a melt flow index of between 0.3 and 10.0 grams per 10 minutes at a temperature of 190? C. under 2.16 kilograms of load; a polydispersity index of 4-24; and a density of 0.943-0.965 grams per cubic centimeter.

Apparatus is provided for expanding plastics material parisons into plastics material containers by a liquid medium, having at least one transforming station, which fills and expands the plastics material parisons with the liquid medium with at least one pressure generating device, which is suitable and intended to deliver the liquid medium to at least one filling device, which filling device fills the plastics material parisons with the liquid medium, wherein the pressure generating device has a pressure outlet which at least at times can be fluidically connected to the plastics material parison to be filled. The apparatus has a removal device which is suitable and intended at least at times to remove a flowable medium from a plastics material container, wherein the pressure generating device has a suction intake which at least at times can be fluidically connected to this removal device in order to remove the flowable medium.

A machine for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The machine includes a container forming and filling station where the preform is placed in a mold having a molding cavity and a forming liquid is injected into the preform thereby forming and filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform thereby forming an assembly. The extension device includes a connection part for attaching to the preform and an extension part defining an inner opening extending in the continuity of the inner opening of the neck of the preform. The extension device remains attached to the neck of the preform at least during the forming and the filling of the container.

The invention relates to an arrangement 1 for feeding contents into a container being formed from a preform 2 in a mold 3, in a machine for simultaneously molding and filling containers made from preforms, wherein the arrangement defines, by the way of its wall 7, a flow path between a contents-supply line 4 and the mouth opening 6 of the container. The arrangement 1 is characterized in that it has a sealing termination both in relation to the contents-supply line 4 and in relation to the preform 2.

A method for producing a container from a preform having a body and a neck defining an inner cylindrical opening. The method including the steps of placing the preform in a mold having a molding cavity, forming the container by injecting a forming fluid into the preform, and filling the container with a liquid. Prior to forming of the container, an extension device is attached to the neck of the preform. The extension device includes an extension part defining an inner opening extending in the continuity of the inner opening of the neck. The extension device remaining attached to the neck of the preform at least during the forming and the filling steps.
