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.
摘要:
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.

An apparatus (1) for the shaping of plastics material pre-forms (10) into plastics material containers (20) with a movable carrier (2) on which is arranged at least one shaping station (4), wherein the shaping station has a blow molding device (6), and wherein the shaping station additionally has a stressing device (12) which acts upon the plastics material pre-forms with a flowable medium for their expansion, wherein the shaping station additionally has a rod-like body (14) which is capable of being inserted into the plastics material pre-forms in order to stretch them in the longitudinal direction (L) thereof, wherein the shaping station has a drive device (24) which moves the rod-like body (14) with respect to the plastics material pre-form. According to the invention a coupling device (30) is provided which couples a movement of the rod-like body (14) with respect to the plastics material pre-form to a movement of the stressing device (12) with respect to the plastics material pre-form (10)—in particular in a mechanical manner—at least for a time, and the apparatus has an influencing device (40) which influences a supply movement of the stressing device (12) towards the plastics material pre-form at least locally.

A blow cylinder and a method for actuating the same are provided. The blow cylinder includes a blow piston and a brake piston, wherein the brake piston is controlled independently of the actuation of the blow piston towards the extended position.
摘要:
An apparatus for fabricating containers. The apparatus including a plurality of mold segments, an injection cylinder, a closure cylinder and a motor cylinder. The injection cylinder defining a mold cavity substantially in the form of a container and accommodating a substantially tubular preform having a preform cavity in communication with an open end. The injection head establishes fluid communication with the preform and the injection cylinder is in fluid communication with the injection head and configured to inject a volume of liquid into the preform The closure cylinder is configured to exert a force on at least one of the mold segments to maintain them in a closed disposition. The motor cylinder is configured to drive the injection cylinder and being itself concurrently driven with the closure cylinder by a single pressure source.

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 system for simultaneously forming and filling a container comprising a mold having a mold cavity defining an internal surface and adapted to accept a preform, a pressure source urging a first liquid toward the preform, means for maintaining a desired saturation of gas in solution in the first liquid, and a blow nozzle adapted to receive the first liquid from the pressure source and transfer the first liquid at a pressure into the preform thereby urging the preform to expand toward the internal surface of the mold cavity and create a resultant container, wherein the first liquid remains within the container as an end product.
摘要:
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.
摘要:
The invention concerns a method of degasification of a carbonated beverage-filled container in an apparatus for blowing and filling containers, the apparatus comprising: —a mold (12) enclosing a blown and carbonated beverage-filled container (14) that comprises a dispensing opening (16), —an injection head (24) that is movable along a longitudinal axis (A) 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 is at a distance from the dispensing opening, characterized in that the method comprises the following steps: i) moving the injection head (24) away from the sealing position (3A) to a non-sealing position (3B). ii) moving back the injection head to the sealing position (30), iii) moving the injection head away from the Position sealing position to a non-sealing position (3D).
