DEVICE AND METHOD FOR MANUFACTURING PLASTIC CONTAINERS
A device for producing plastic containers (10) by means of a molding, filling and sealing process is disclosed, at least consisting of a molding device (16) having individual molding tools (18), which can be moved repeatedly relative to one another from an open receiving position into a molding sealing position, and an extrusion unit (12), which can be used to insert at least one extruded plastic hose (14) into the open receiving position of the molding tools (18), which is characterized in that a traversing unit (20) can be used to move the extrusion unit (12) in conjunction with each extruded plastic hose (14) in opposite directions with respect to the molding device (16), which is stationary in every position of the molding tools (18).
Fuel tank
A fuel tank includes a built-in component having a head portion, a neck portion, and a shoulder portion, the built-in component being anchored to a tank body by blowing air from outside a parison to cause the parison wrap around the neck portion during molding of the tank body. A slit extending in one direction only is formed on a surface of the shoulder portion as an air vent path.

PLASTIC CONTAINER FOR FLUIDS AND METHOD FOR PRODUCING A PLASTIC CONTAINER
A plastic container and a method for producing a plastic container for liquids, in particular an inner container for transport and storage containers for liquids comprising an outer jacket made of latticework or of sheet metal material and a pallet-type understructure, the plastic container being realized as a blow-molded body by blow molding from a tubular preform in a blow mold and having a container socket for connecting a container fitting in a fitting connecting area of a container wall, the container socket being provided with a container opening and being connected to a connecting flange of the container fitting via a welded joint, wherein the container wall has an inner layer made of a first plastic material and an outer layer made of a second plastic material, and the container socket has a longitudinal cross section widening toward the container opening in such a manner that an end face of the container socket is formed at least in part by an inner layer segment disposed opposite the outer layer, and a welding contact surface of the container socket is formed by the inner layer segment.
Method and tool for manufacturing a plastic container, in particular a fuel container, by means of internal pressure forming
A method for manufacturing a plastic container by internal pressure forming including positioning a tubular preform between the die parts of a molding die having a die cavity; closing the molding die and forming or preforming a container from the preform using internal pressure, wherein a peripheral portion of the preform is pressed out of the die cavity through a die gap; laterally withdrawing the peripheral portion pressed out of the die cavity, as a result of which the container is divided into two container halves; and thermally separating plastic bridges and/or plastic threads which arise during the lateral withdrawal of the peripheral portion. Also disclosed is a molding die suitable for carrying out the method.

Multilayer plastic bottles with mineral filler and foamed layer for improved recyclability
Plastic containers exhibiting reduced plastic resin usage, while maintaining a specific gravity of below 1.0, so as to allow their quick and easy separation using floatation techniques during recycling. Within a layer or portion some of the plastic resin of the container body may be replaced with an inorganic mineral filler material, while within another layer or portion of the plastic container, the plastic material (e.g., polyethylene, polypropylene) may be foamed. The fraction of mineral filler material that may be included within the polyethylene may thus be increased beyond that previously possible while maintaining the specific gravity below 1.0, by also foaming a layer or portion of the polymeric material, so as to create voids therein. This allows significantly less resin material to be employed, while maintaining strength characteristics of the plastic container so as to be at least comparable to existing plastic containers not including such mineral filler materials.
