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.

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 method for manufacturing a resin container part includes: injection-molding of a bottomed resin preform including, on a bottom portion thereof, a thick bulging portion that retains residual heat by which the bulging portion is deformable by being pressed to follow a shape of a blow cavity mold; and a blowing including stretching a body portion of the preform by applying a blow pressure to the preform and forming a joint portion by pressing the bulging portion of the preform with an upper bottom mold to deform the bulging portion to follow the shape of the blow cavity mold.

The invention relates to a method for the manufacture of at least one flexible plastic container, according to which method each container (10) comprises two separate walls (12, 13) facing one another joined at their circumference by a sealed peripheral edge (14), said separate walls defining a storage space of the container (10). According to the invention, at least the following stages are realized: a) Forming a pile of two sheets (26, 27) of plastic material, said sheets (26, 27) being laid one against the other, the surfaces which face one another of these sheets (26, 27) being placed directly in contact with one another without any element acting as an interface, b) Simultaneously shaping said sheets (26, 27) thus laid one against the other in order to define said at least one container (10) without having previously separated these sheets, at least each container (10) being partially formed, said sheets (26, 27) being maintained lying one against the other in at least one section of the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of each container (10) during this shaping and c) Sealing at least partially the areas of said sheets (26, 27) intended to constitute said peripheral edge (14) of at least each container (10).

Provided are a blow-molding mold, a bottle blowing machine and a plastic bottle, the blow-molding mold has a mold cavity, where a bottle body, a bottle shoulder, a handle and a bottle neck are formed within the mold cavity after a bottle preform is blown, the bottle shoulder is located between the bottle body and the bottle neck, one end of the handle is connected to the bottle shoulder, the other end of the handle is connected to the bottle shoulder or the bottle neck, and the mold cavity includes a first concave region to have a raised step structure formed on the bottle neck.

Provided are a bottle blowing mold, a bottle blowing machine and a plastic bottle, the bottle blowing mold includes a mold cavity, where a bottle body, a bottle shoulder, a handle and a bottle neck are formed within the mold cavity after a bottle preform is blown, the bottle shoulder is located between the bottle body and the bottle neck, one end of the handle is connected to the bottle shoulder, an other end of the handle is connected to the bottle shoulder or the bottle neck, and a cavity wall of the mold cavity is provided with at least one first rib to have a non-closed or annularly closed first groove is formed on the bottle body.

A tubular molded body that can reduce restrictions on attachment to another member to be easily attached to another member. The tubular molded body 10 includes a tube main body 11 formed in a tubular shape and an attachment flange 100 formed in a flange shape to project from the tube main body 11. The attachment flange 100 includes a thin-walled hinge 130 and is rotatable by the hinge.

A method produces a filled and closed container by the blow-moulding, filling and closing method. An initially open container part (52) is held in a mould (46) and has been vacuum-moulded and/or blow-moulded by a blow pin and is filled successively with media (74, 76) of different types, in particular viscosity, by metering units (12, 14) via its free, upwardly directed container-part opening (54). 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.

A method for manufacturing a resin container part includes: injection-molding of a bottomed resin preform including, on a bottom portion thereof, a thick bulging portion that retains residual heat by which the bulging portion is deformable by being pressed to follow a shape of a blow cavity mold; and a blowing including stretching a body portion of the preform by applying a blow pressure to the preform and forming a joint portion by pressing the bulging portion of the preform with an upper bottom mold to deform the bulging portion to follow the shape of the blow cavity mold.

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.
