摘要:
A method of degasification of a carbonated beverage-filled container in an apparatus for blowing and filling containers, the apparatus including a mold enclosing a blown and carbonated beverage-filled container. The container includes a dispensing opening, an injection head that is movable along a longitudinal axis, passing by the dispensing opening of the container, between a sealing position in which the injection head is in a sealing engagement with the dispensing opening and a non-sealing position in which the injection head spaced from the dispensing opening. The method includes the steps of moving the injection head away from the sealing position to a first non-sealing position, moving the injection head from the first non-sealing position back to the sealing position, and after moving the injection head back, moving the injection head away from the sealing position to a second non-sealing position that is different from the first non-sealing position.

The invention relates to a method for producing a container from thermoplastic material having a connection element (5) passing through the wall thereof. The method comprises making available at least one plate-shaped or shell-shaped or tube-shaped preform (3) made of plasticized thermoplastic material, introducing the preform (3) into a multipart molding tool (1) having cavities defining at least one molding recess, molding and final shaping of the preform (3) within the molding tool (1) using differential pressure, piercing of the still warm-plastic preform (3) from the tool side by means of a mandrel (9) in order to produce an opening (6) in the preform (3), insertion from the molding recess side of a connection element (5) into the opening (6) produced by the mandrel (9), and connection of the connection element (5) to the preform (3).

An apparatus and method for simultaneously forming and filling a plastic container is provided. A mold having a mold cavity defines an internal surface and is adapted to accept a preform. A pressure source is operable to draw liquid through the inlet and urge it into the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container. A pressure compensation system can exert a clamping force on the mold in response to the pressure source. The liquid remains within the container as an end product.

The invention relates to blowing equipment (1) that uses a pressurised fluid for blowing vessels from preforms of a thermoplastic material and including a body (3) and a neck (6), wherein said equipment comprises a blowing mould (5) with a moulding cavity (4) in which the body (3) of a preform (2) can be placed, said mould (5) including an upper surface (7) from which protrudes the neck (6) of a preform (2) once the body (3) of said preform (2) is placed in the cavity (4), and wherein said equipment (1) also includes a nozzle (8) with an end (9) shaped so as to be placed in functional sealed relation with the protruding neck (6) of the preform (2). The end (9) of the nozzle (8) is connected to a means (12) for degassing the blowing fluid, capable of bearing tightly on the upper surface (7) of the mould (5) so as to define an inner volume (13) in which the blowing fluid blown under pressure into the preform (2) can be discharged after the preform (2) blowing operation. The equipment includes a degassing means capable of expanding the blowing fluid around the blowing cavity, wherein said means includes a plurality of channels (28) arranged around said blowing cavity, said channels (28) having one side opening into the inner volume of the degassing means (12) while the other side gives into an annular channel (29) for discharge into the atmosphere.

Disclosed is a mold hanger for supporting a bottle mold in a blow molding station, the mold hanger comprising a piston and piston sleeve fully contained within the mold hanger configured to push a moveable insert into the mold. Also disclosed is a method of retrofitting an original rotatable blow molding module having multiple existing blow molding stations, each existing mold hanger defining an existing outer envelope. The disclosed method may include providing an improved mold hanger substantially contained within the respective existing outer envelope and including low-profile drive mechanisms configured opposably to drive moveable inserts into the mold. Further disclosed is a method of manufacturing a blow molded bottle with a deep pinch grip, the method including providing within a mold hanger a drive mechanism to drive a moveable insert into the mold. A bottle made by such methods is also disclosed.

摘要:
A blow molding system for a thermoplastic blank which is supported in a mold. The system includes a fixed tubular body connected to a high-pressure fluid source and, at the lower end thereof, supporting moveable equipment consisting of a tuyere, the tuyere being defined laterally by a terminal sleeve of the moveable equipment and the bottom thereof being the front wall of the body, wherein the lateral inner wall of the sleeve is configured in such a way that the pressure of a fluid inside the tuyere does not result in a reaction force component on the lateral wall, which is directed opposite to the wall of the mold.
摘要:
A method for forming and filling a container with liquid. The container being formed from a preform located within a mold and the method utilizing a hydraulic blow molding device that is coupled to a source of the liquid, which is used as the blow molding medium. The hydraulic blow molding device has a blow nozzle and a member that is extended from a retracted position to a position within the preform. A blow nozzle engages in fluid tight communication with an open end of the preform so as to provide a sealing engagement of the blow nozzle with the preform. The liquid blow medium is injected into the preform so as to form the container after sealing engagement of the blow nozzle with the preform. The member initiates its advancement into the preform prior to the time of sealing engagement of the blow nozzle with the preform.
