Ways for controlling a level of a product in a container are provided that include engaging an exterior surface of the container containing the product at a first product level. A force is applied to the exterior surface of the container to cause the container to change from a first volume to a second volume. Cessation of the force results in the container containing the product at a second product level. The second product level can provide an accurate and reproducible final product level in the container.

Method of fluid forming and filling containers

Ways for simultaneously forming and filling a container with a liquid product are provided that include a mold cavity, a dispensing means, a blow nozzle, a conduit, and a hydrophobic surface. The mold cavity defines an internal surface and accepts a preform. The dispensing means receives the liquid product and dispenses a charge of the liquid product. The blow nozzle transfers the charge of the liquid product dispensed from the dispensing means into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container. The liquid product remains within the container as an end product. The conduit fluidly couples the dispensing means to the blow nozzle. The hydrophobic surface contacts the liquid product when the system simultaneously forms and fills the container, where the hydrophobic surface forms part of the dispensing means, the blow nozzle, and/or the conduit.

Container forming system with hydrophobic properties

Ways for simultaneously forming and filling a container with a product are provided that include a mold cavity, a two-stage injection unit, and a blow nozzle. The mold cavity defines an internal surface and is configured to accept a preform. The two-stage injection unit receives and dispenses the product where a first stage includes an extruder and a second stage includes an accumulator. The extruder imparts mechanical energy to the product to reduce a viscosity of the product and transfers the reduced-viscosity product to the accumulator. The accumulator receives the reduced-viscosity product from the extruder and dispenses a charge of the reduced-viscosity product. The blow nozzle transfers the charge of the reduced-viscosity product dispensed from the accumulator into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container.

Container forming and filling using high viscosity product

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.

Reduced material container and method of forming same

Ways for simultaneously forming and filling a container are provided. A hydraulic intensifier () receives a first liquid () and dispenses the first liquid () at a first pressure, where a moveable member () having a first surface () contacts the first liquid () and a second surface () contacts a second liquid (). The second liquid () provides a second pressure on the second surface () so that the first pressure is applied to the first liquid () by the first surface (). The first surface () has a smaller area than the second surface () and the first pressure is greater than the second pressure. A blow nozzle () transfers the first liquid () at the first pressure into a preform () within a mold cavity () to urge the preform () to expand toward an internal surface () of the mold cavity () and form a resultant container. The first liquid () remains within the container as an end product.

High pressure process of forming and filling a container

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 ().

An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity () is provided. A pressure source () includes an inlet () and a piston-like device (). The piston-like device () is moveable in a first direction wherein liquid is drawn into the pressure source () through the inlet () and in a second direction wherein the liquid is urged toward the preform (). A blow nozzle () may be adapted to receive the liquid from the pressure source () and transfer the liquid at high pressure (P) into the preform () thereby urging the preform () to freely expand until an unopened end thereof contacts a platen (). The platen () forms a bottom in a resultant container. The liquid remains within the container as an end product.

Free blow bottle design

A method of making a container via a simultaneous filling and forming of the container with a liquid product is disclosed. The method comprises the steps of extruding a parison (), capturing a portion of the parison () within a mold (), and inflating the captured portion of the parison () against the mold (). The captured portion of the parison () is inflated against the mold () by introducing the liquid product into an interior of the captured portion of the parison (), wherein the liquid product forms an end product to be sealed within the resultant container.

Method of extrusion blow molding using a liquid

Systems and methods for simultaneously forming and filling a container are provided where a pressure source is accelerated from an initial state to attain a predefined process speed while applying pressure to a volume of fluid. The volume of fluid is fluidly coupled to a preform upon attaining the predefined process speed, the pressure source directs at least a portion of the volume of fluid into the preform and stretching the preform to form the container, where the container includes at least the portion of the volume of fluid. The volume of fluid is fluidly decoupled from the container and the pressure source is then decelerated from the predefined process speed toward the initial state.

Method of blow molding

A method and a preform for blow molding to form a plastic container are disclosed, the preform having a coating formed on an inner surface thereof. The coating reduces a loss of heat energy from the heated preform during expansion thereof to ensure the preform maintains a temperature at or above the phase change/solidification temperature of the material forming the preform.
