Method for producing tilled containers from parisons made from a thermoplastic material, wherein the respective parison is at least conditioned thermally and is subsequently shaped during a shaping and filling phase in a mold by the action of the pressure of the supplied filling substance into the respective container at a shaping and filling pressure, wherein, during the shaping and filling phase, the parison is guided at least temporarily through a stretching rod and/or is stretched in the axial direction, and wherein, at least at the end of the shaping and tilling phase, the respective container has an internal pressure which corresponds to the shaping and filling pressure (p2).

Two stage liquid blow molding method with heat sensitive ingredient

A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a first molding step of liquid blow molding the preform into a halfway shape by supplying, into the preform that has been heated to a predetermined temperature, a first liquid at a predetermined pressure through a nozzle unit; and a second molding step, performed after the first molding step, of liquid blow molding the preform by supplying a second liquid into the preform at a predetermined pressure through the nozzle unit.

APPARATUS FOR FORMING PLASTIC PREFORMS INTO PLASTIC CONTAINERS WITH PREFORM COOLING

Provided is an apparatus for forming plastic preforms into plastic containers, having a blow mould which forms a cavity within which the plastic preforms can be expanded to form the plastic containers, and having an application device which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, which is suitable and intended for acting upon the plastic preforms with a flowable medium in order to expand them, wherein the application device is placed against a mouth area of the plastic preforms in order to act upon these with the flowable medium. The application device forms at least one first flow channel for the flowable medium, which guides and/or directs at least a portion of the flowable medium to an inner wall of the mouth area in order to temper and, in particular, cool this inner wall.

Disclosed is a method for manufacturing a container made of plastic, including the following steps: continuously extruding a hose, positioning an opened blow mold around the hose, so that the hose is arranged between the two blow mold halves, closing a hose gripper arranged at the blow mold to clamp the hose and simultaneously keeping the hose open at its upper side to form an inlet opening, separating the hose above the hose gripper to form the preform, horizontally moving the blow mold together with the preform hanging therein and held by the hose gripper into a blowing position, moving a blow mandrel assembly from above into the inlet opening of the preform, closing the blow mold halves, and inflating the preform in the blow mold to form a container.

Liquid blow molding method and liquid blow molding apparatus

A bottomed tubular-shaped preform is molded into a liquid-containing container holding a content liquid, by supplying, through a first supply path, a first liquid at a predetermined pressure into the preform that has been heated to a predetermined temperature to liquid blow mold the preform and by supplying, through a second supply path that is different from the first supply path, a second liquid into the preform after or simultaneously with the supply of the first liquid.

Telescoping fill station shroud for a blow/fill/seal packaging machine

In a blow/fill/seal packaging machine, aseptic environment is provided by a telescoping fill station shroud through which a sterile curtain gas flows. The telescoping fill station shroud includes an open-ended lower sleeve, an open-ended upper sleeve slidably coacting with the open-ended lower sleeve, and a manifold plate mounted over a proximal end portion of the upper sleeve.

Liquid blow molding method

A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source; and a molding step of liquid blow molding the preform by simultaneously supplying, to the preform, the first liquid pressurized to a predetermined pressure by the first pressurizing source and the second liquid pressurized to a predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source.
