Abstract: A pallet container for storing and transporting liquid filling materials includes an plastics inner container and a supporting casing which closely encloses the plastics inner container and is made of a tubular lattice frame which is fastened to an upper outer rim of the pallet. The pallet has a flat pallet top deck for supporting the inner container, and a pallet substructure having four corner feet and four middle feet arranged there between, and a horizontally peripheral bottom ring. The pallet top deck is made of a flat, planar rectangular metal plate which has on each outer side a short downward-facing folded edge extending along the outer sides. The folded edge is pressed by the tubular lattice frame against the corner and middle feet into a folded-edge conforming recess and is fixed such that the metal plate is spanned at its four outer sides linearly on the pallet substructure.

A transportation securing eye made of metal is provided and fastened on the pallet top deck of the bottom pallet (12) in each of all four corner regions externally at the bottommost horizontally peripheral lattice tube of the tubular lattice frame.

Abstract: A pallet container for storing and transporting liquid filling materials includes an exchangeable thin-walled inner container of thermoplastic, and a tubular lattice frame closely enclosing the inner container and made of vertical and horizontal tubular bars. The tubular lattice frame is fastened to the upper outer rim of a bottom pallet having a flat pallet top deck which includes a sheet-metal plate for supporting the inner container and a pallet substructure having four corner feet, four middle feet arranged there between, and a steel-tube base ring that is horizontally peripheral on the bottom side. The pallet substructure has four individual tube sections which extend diagonally directly beneath the metal plate and are each fastened to two adjacent middle feet to form a diamond-shaped supporting frame beneath the bottom plate. The tube sections are connected to base ring in an electrically conductive manner via corresponding screw connections.

Abstract: A pallet container for storing and for transporting liquid filling materials includes a base pallet, a lattice frame fastened thereon and made of metal bars, and a fabric cover suspended in the lattice frame for accommodating a liquid-tight inliner for receiving the liquid filling material. The fabric cover and the inliner with preassembled filling and removal fitting is provided in the delivery state as a separately premanufactured, flat-folded package in the form of a modular unit which can be exchanged only as a complete modular unit. To bring the pallet container into a use-ready state, the unfolded fabric cover is fastened by straps to the upper lattice frame, and the removal connection piece of the filling and removal fitting is fastened with an adapter plate to the lower area of the lattice frame by a snap/latching connection.

Abstract: A pallet container for storing and for transporting a liquid filling material includes a base pallet, a lattice frame fastened thereon and made of metal bars, and a fabric cover suspended in the lattice frame and accommodating a liquid-tight inliner composed of a plastics film and/or metal foil for receiving the liquid filling material. The inliner arranged within the cube-shaped fabric cover is designed, for gas-assisted emptying, as a double chamber inliner with a rear chamber for blowing in compressed air or gas and a front chamber for receiving the liquid filling material. A film or foil separating wall located in-between avoids the sensitive filling material from directly contacting the blown-in compressed air.

Abstract: The present invention relates to a method and a device for cleaning extrusion heads (10) in the extrusion of thermoplastic plastic materials which are ejected or extruded as tubular preform (12) from an extrusion nozzle (14). For removing interfering deposits and cakings (20) on the discharge nozzle (14), according to the present invention the tubular preform (12) is briefly deflected and upset, wherein the deposits (20) adhering in a proximate region of the discharge nozzle (14) are wiped off from the tubular preform (12) and transported away. Advantageously, the tubular preform (12) is during its deflection itself used as cleaning element, wherein the cleaning takes place automatically during the continuous operation of the continuous extrusion without interrupting the production process.

Abstract: A pallet container includes a bottom pallet and a thin-walled inner container, made of thermoplastic material and resting on the bottom plate, for storing and transporting liquid or free-flowing goods. Closely surrounding the plastic container is a lattice tube frame which includes vertical and horizontal tubular rods welded to one another and which is securely fixed to the bottom plate. In order to improve the lattice tube frame durability while maintaining sufficient stacking load-bearing capacity, at least the vertical tubular rods have regions of low tubular profile height and high tubular profile height, wherein the regions of low tubular profile height are uniformly linear and positioned outside the intersections, and the regions of high tubular profile height are positioned in an area of the intersections.

Abstract: A multilayer thermoplastic container for storing and transporting liquid contents, especially combustible or explosive contents, is made of at least three superimposed layers and includes at least one layer for discharging an electric charge. The innermost layer of the container in contact with the liquid content is made of virgin material and a second integrated inner layer which is covered by the innermost virgin material layer is electrically conductive as a result of incorporated additives, e.g. conductive carbon black and is covered on the outside by another electrically non-conductive layer. Electric charge carriers that accumulate on the surface of the thin inner layer due to the friction with the content are “suctioned through” large areas of the inner, electrically non-conductive layer by the second, electrically conductive layer and discharged.

Abstract: The invention relates to a lidded container for storing and transporting in particular hazardous liquid fill goods, including an outer container body, an upper container lid and an inserted thin-walled inliner. The container lid has at least one filling and emptying opening that can be closed in a gas and liquid tight manner and that, for example, can be attached by means of a U-shaped tension ring closure or without tension ring as a snap cover by means of snap closure or a screw cap by means of screw closure on the upper container opening of the container body on a correspondingly designed flange edge. The thin-walled inliner (26) is fixed on the bottom side of the container lid (14) in the outer peripheral region in a gas and liquid tight manner, wherein the container lid (14) and inliner (26) form a gas and liquid tight hollow body unit. The container body, which can be used multiple times, is only provided as a support and protection unit for the inliner.

Abstract: A pallet for a pallet container for storing and for transporting liquid contents has an upper deck made of profiled sheet steel and a substructure having a plurality of plastic feet or runners. The pallet is grounded electrically. In order to ensure a reliable electrical discharge (electrical grounding) of, for example, electrostatic charging, accompanied by the properties of a high resistance to mechanical loading, fewer than half the plastic feet or runners are made of plastic material which is electrically conductive and more than half the plastic feet or runners are made of plastic material which is not electrically conductive.
