A manufacturing method for manufacturing a container with a handle, the method including a primary blow molding step of blow-molding a preform made of a polyethylene terephthalate resin to mold an intermediate molded body, and a secondary blow molding step of assembling the handle to a container body, which is made of the intermediate molded body expanded inside a blow mold, by arranging the intermediate molded body inside the blow mold which holds the handle by an inner surface thereof and blow-molding the intermediate molded body in a state where the handle is brought close to the intermediate molded body.

Method for forming a holder (1), by blow moulding, with a wall (3), whereby a preform is pushed against a first and second mould part (10, 11) to form an intermediate form, in which the second mould part (11) is moved and takes the intermediate form with it in order to form an edge (5) between the first and second mould part (10, 11), whereby the mould parts (10, 11) are such that the edge (5) includes a first and second edge part (13, 14)), of which the second (14) is closer to the wall (3) than the first, of which the first (13) makes an angle () to the direction of movement of the second mould part (11) and of which the second (14) makes a larger angle () to it.

Blow molded components and systems and methods for forming the same are disclosed. The blow molded component may be an air duct, for example, a structural air duct. The structural air duct may include a hollow main body including a first layer of a first material and a second layer of a second material surrounding the first layer. At least one hollow protrusion may extend from the hollow main body and may include proximal and distal portions. The proximal portion may include the first layer surrounded by the second layer and the distal portion may include only one of the first and second layers. The duct may be formed by blow molding a multi-material parison. The first and second materials may have different tensile moduli, and during the molding process the material with the higher modulus may tear and allow the lower modulus material to fill the protrusion.

A blow mold assembly is disclosed having removable neck insert mold components for forming features of a container for engaging a removable container closure and manually operable retention devices for releasably retaining the neck insert mold components with mating mold components of the mold assembly. Advantageously, each manually operable retention device includes a clamp mechanism movable between a release position and a clamp position by manual operation and the clamp mechanism is effective to resist forces acting on the clamp to move the clamp to a release position when the clamp is in the clamp position. Each manually operable retention device is retained with an associated mating mold component when a neck insert mold component is removed from or installed to the mold assembly.

A resin fuel tank includes a peripheral wall portion that is configured to structure a portion of a fuel tank main body portion that is made of resin and in which fuel is stored, the peripheral wall portion having a parting line portion that is visible from an outer side of the fuel tank main body portion, and a projecting portion that is solid, is disposed along the parting line portion, and is configured to project outward, integrally with the peripheral wall portion, from the peripheral wall portion toward the outer side of the fuel tank main body portion.

A method for producing a plastic container by internal pressure forming including arranging a hose-shaped preform between the molding dies of a mold, formed having a mold cavity; closing the mold and forming or preforming a container from the preform by internal pressure, wherein a circumferential section of the preform is pressed through a mold gap into a chamber surrounding the mold cavity and is pressed in the chamber against claw pairs having stationary inner retaining claws and movable outer tear-away claws; and laterally moving the outer tear-away claws, causing the circumferential section between the outer tear-away claws and the inner retaining claws to be torn open and the container to be split into two container halves. Also disclosed is a mold suitable for performing the method.

The invention relates to a method for producing a filled and closed container, in particular by way of the blow-moulding, filling and closing method, in which an initially open container part (52) that is held in a mould (46) and has been vacuum-moulded and/or blow-moulded by means of a blow pin is filled successively with media (74, 76) of different types, in particular viscosity, by means of metering units (12, 14) via its free, upwardly directed container-part opening (54), such that the filled-in media (74, 76) are separated from one another in the container part (52), and subsequently, by closing of the top mould halves (56, 58) of the mould (46), a container top part (60) is moulded and the container part (52) is closed, forming the container.

Injection stretch blow molding tooling for forming at least one parison and at least one stretch blown article having an integral handle. The tooling includes at least one cavity block, a body mold supported within the cavity block, a handle mold supported within the cavity block, and a thread split assembly positioned adjacent to said cavity block. The thread split assembly includes first and second thread split halves shiftable between an open position and a closed position. As such, the body mold, the handle mold, and the thread split assembly cooperatively define a parison-forming cavity, with such parison-forming cavity including a body cavity for forming a body of the parison and a handle cavity for forming a handle of the parison.

A method of producing a container and a closure comprises blow molding a body comprising a container portion and a closure portion joined together, and separating the closure portion from the container portion. A container and/or a closure produced according to the method are also disclosed, as well as an intermediate product for producing a container and a closure.

Disclosed is a molding unit for the forming of a container provided with a hollow recess toward the interior of the container, including: a mold provided with a lateral wall defining a cavity having the impression of at least one portion of the container, provided with a housing formed hollow in a protrusion forming a projection toward the interior of the cavity and opening into the cavity; and a boxing device having an insert mounted in translation relative to the lateral wall between a retracted position in which the insert is retracted in the housing, and a deployed position in which the insert projects outside of the housing, a projection whose transverse extension is less than or equal to 85% of the cumulative transverse extension of the protrusion and of the insert.
