Method and apparatus for the fabrication of a container, such as a beverage container
A method for the fabrication of a container (802), comprising the steps of: providing a preform (705), said preform being substantially tubular in form and being provided with a closed end (709), a cavity (707), and an open end (710) communicating with said cavity (707); positioning at least one restriction device (711, 714) relative to the preform (705) so as to define at least one restriction zone and restrict expansion of the preform (705) therein; injecting a pre-determined volume of an incompressible fluid (800) into the cavity (707) of the preform (705) via the open end (710), provoking the preform (705) to plastically deform by expansion, said preform (705) expanding freely in at least one expansion zone outside said at least one restriction zone; and Using for the fabrication of a beverage container (802).
DEVICE FOR BLOW MOULDING CONTAINERS
The device is used for the blow-molding of containers. A preform made of thermoplastic material, following a thermal conditioning within a blow-mold, is stretched by a stretching rod and is reshaped by effects of blowing pressure into the form of a container. A specification for the positioning of the stretching rod occurs through the use of a linear drive. Blowing pressure is created through the use of at least one positionable blowing gas supply. The linear drive is at least intermittently mechanically coupled with the positionable blowing gas supply and the stretching rod in such a way that coordinated movement kinetics are carried out. The coupling means and the coupled elements are constructed in such a manner that the axis of motion and the resulting force-effect axis form a common spatial axis.
METHOD FOR HYDROFORMING A CONTAINER FROM A PREFORM
A method of hydroforming a container from a preform. During the method, an injection nozzle is moved from a retracted position, where the nozzle is spaced away from the neck of the preform, to an intermediate position, where contact is established between a first contact surface of the nozzle and the finish of the preform. The nozzle is then moved from the intermediate position to an injection position, where a second contact surface of the nozzle abuts an abutment surface and the neck is axially compressed. With the nozzle in the injection position, a liquid is injected from the nozzle into the preform causing the preform to expand and form the container.
Method for hydroforming a container from a preform
Assembly (30) of a preform (32) and a station (34) for hydroforming a container from the preform, wherein: the preform has a neck (44) extending along an axial direction (D), the neck comprising a support ring (46), and a finish (48), the station comprises a mold (36) in which the preform is placed, the support ring being in contact with a support surface (56) of the mold, the station comprises an injection nozzle that is movable along the axial direction with respect to the mold from a retracted position to an intermediate position, wherein a contact is established between a first contact surface (72) of the nozzle and the finish, and further to an injection position, wherein a second contact surface (74) of the nozzle abuts on an abutment surface (76) and the neck is axially compressed between the support surface and the first contact surface, the first contact surface being less deformable than the neck in the axial direction, and the station is adapted for injecting a liquid from the nozzle into the preform when the nozzle is in the injection position, and the abutment surface is fixed along the axial direction with respect to the mold at least during the injection.
Nozzle tool system and extrusion blow molding arrangement
A nozzle tool system for extrusion blow molding has an intermediate module and at least first and second nozzle outlet units, each forming an adjustable nozzle outlet gap between a mandrel extending axially and a deformable sleeve. The units can be connected with the intermediate module as replacements for one another, and have a first outlet diameter and a larger second outlet diameter different from one another. At least one setting drive for reversible deformation of the sleeve is arranged on the intermediate module and can be connected with the deformable sleeve by way of a releasable coupling arrangement. The first nozzle outlet unit delimits a first setting path of the setting drive, using at least one inner mechanical stop, and the second nozzle outlet unit delimits a second setting path of the setting drive, greater than the first setting path, using at least one inner mechanical stop.
MEDICAL FLUID CONTAINER
A medical fluid container includes a container interior and a connecting piece that forms an inner channel. The container interior can be accessed from the outside via the connecting piece. The connecting piece has an outer thread on a connecting piece longitudinal section. The inner channel expands in a substantially conical manner in a region of the outer thread, starting from the container interior, to then preferably transition into a first cylindrical channel shape which extends to a free opening of the connecting piece. A method can be used for producing the medical fluid container from a container blank.
Method of degasification of a carbonated beverage-filled container
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).
Multiple-staged fluid operated actuator
A multiple-stage fluid operated actuator (100) is provided. The multiple-stage fluid operated actuator (100) comprises a housing (101) including a first bore (212) with a first cross-sectional area and a second bore (215) with a second cross-sectional area. The multiple-stage fluid operated actuator (100) further comprises a piston assembly (210) including a first piston (210a) movable within the first bore (212) and a second piston (210b) movable within the first and second bores (212, 215). The piston assembly (210) separates the first and second bores (212, 215) into a first fluid chamber (214a) selectively in fluid communication with a pressurized fluid source (220) or an exhaust, an airtight second fluid chamber (214b), and a third fluid chamber (214c) selectively in fluid communication with the pressurized fluid source (220) or the exhaust.
MOULD SYSTEM AND METHOD
A mould system for moulding a receptacle is described. The mould system comprises a mould comprising a mould cavity and an opening, and a mandrel system comprising a reference point, a mandrel and an expandable member. The mandrel is at least partially located, or at least partially locatable, inside the expandable member and comprises one or more holes through which a fluid is flowable in use from an interior of the mandrel to an exterior of the mandrel to expand the expandable member. When the mandrel is at least partially located inside the expandable member, the mandrel system is positionable relative to the mould such that the reference point is at a fixed position relative to the mould and the mandrel, and the expandable member extend into the mould cavity through the opening such that there is a clearance between the expandable member and a base of the mould cavity opposite the opening. The expandable member and at least a part of the mandrel are moveable relative to the reference point to vary the clearance.
