An injection device for simultaneously forming and filling a container by injecting a pressurized liquid in a preform. The device includes a molding cavity, a pressurized liquid source and an injection nozzle in fluidic communication with the pressurized liquid source. The injection nozzle is arranged to be placed in fluidic communication with a preform in the molding cavity. A liquid injection circuit is defined by the injection nozzle, the pressurized liquid source and the preform. Also provided is a volume measuring feature for measuring the volume of liquid injected in the preform from the pressurized liquid source and a pressure measuring feature for measuring the pressure in the liquid injection circuit.

BLOW MOLDING DEVICE

A blow molding apparatus is configured to blow mold a preform into a container by supplying a pressurized incompressible fluid into the preform from a pressurized fluid supply unit. The blow molding apparatus includes: a drawing and discharging flow path connected to a drawing orifice; a fluid drawing source to apply drawing force to the drawing and discharging flow path, after blow molding is completed and after and/or while the blow nozzle is moved to a standby position, to draw the incompressible fluid adhering to the blow nozzle; and a pressurized gas supply source to supply a pressurized gas to the drawing and discharging flow path, after blow molding is completed and after a next preform is placed into the mold, to cause the incompressible fluid inside the drawing and discharging flow path to flow out toward the inside of the preform or toward the inside of a container.

11390012 · 2022-07-19 · ·

A hydraulic blow molding apparatus having a container forming station with a forming head coupled to a source of liquid blow medium. The container forming station further includes a mold configured to receive a preform and has interior surfaces that define the container shape. The container forming station injects a liquid end product into the preform and expands the preform to simultaneously form and fill a container with the liquid end product. Prior to the container being removed from the container forming station and while it is still full of the liquid end product, a seal is engaged with the container.

Method of delivering a liquid volume and associated apparatus

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.

Foaming and fill level control through stretch rod

Methods and systems for simultaneously forming and filling a container from a preform with fluid, adjusting a fill point of the fluid, and removing air and/or foam from within the container. One of the methods includes injecting fluid from a fill source into the preform through a nozzle passage defined between the nozzle and a seal pin of the forming and filling system to simultaneously form the container from the preform and fill the container. After the container is formed and filled, the seal pin is actuated to close the nozzle passage and prevent fluid and air from exiting the container through the nozzle passage, thereby trapping fluid and air within the container under pressure. Air, fluid, and/or foam is extracted out from within the container through a passageway defined within a stretch rod to adjust a fill point of the container.

Method for manufacturing liquid-containing container

A liquid container manufacturing method includes: a liquid blow molding step of molding a preform into a liquid container; and a headspace formation step of forming a headspace, by discharging, in a state in which a liquid supply path is closed, a liquid out of the liquid container through a discharge port, the discharge accomplished by drawing-in by a liquid drawing source. In the headspace formation step, a pressurized gas is supplied from a pressurized gas supply source into the liquid container through a gas supply port to thereby assist the discharge, by the drawing-in, of the liquid out of the liquid container through the discharge port, and, when a pressure in a discharge path has increased to a set value, the supply of the pressurized gas by the pressurized gas supply source is stopped.

CONTAINERS FORMED OF POLYOLEFIN RESIN

A preform configured to form a container when the preform is seated in a cavity of a mold and the preform is expanded within the cavity of the mold by introducing an incompressible fluid under a blow pressure into the preform to stretch the preform to assume a shape of the surrounding cavity. The preform includes a high-density polyethylene (HDPE) resin having: 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 through a test fixture of ASTM D1238; a polydispersity index of 4-24; and a density of between 0.943 and 0.965 grams per cubic centimeter.

POLYOLEFIN RESINS FOR CONTAINERS

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.
