Abstract: A pallet container for storing and transporting in particular flammable or easily ignitable liquid filling materials includes a thin-walled rigid internal container made from a thermoplastic plastics material, a tubular lattice frame that as a supporting jacket tightly encloses the plastics-material internal container, and a base pallet on which the plastics-material container bears and to which the tubular lattice frame is fixedly connected. The plastics-material internal container on all sides is enclosed by a fire-protection insulation mat which, while dispensing with a sheet-metal sheathing on all sides, is disposed directly between the tubular lattice frame and the plastics-material internal container. The fire-protection insulation mat is configured in a double-layered manner, and has an internal layer made from a heat-resistant non-woven and an external heat-resistant woven-fabric textile layer.

Abstract: A container includes a base, and a jacket adjoining the base and having a peripheral flange which defines an opening cross section which can be closed by a cover. The cover includes first snap-fit hooks distributed about a periphery of the cover for engagement in complementing first latching openings in the peripheral flange to thereby establish a form fit that prevents a movement away from the base and parallel to a vertical axis of the container in perpendicular relation to the base. The peripheral flange has four corner regions, each provided with a second latching opening for engagement of a second snap-fit hook of the cover. The second latching opening has at least one portion configured curved or inclined in relation to both a transverse axis and a longitudinal axis of the container, or has at least two straight portions extending at an inclination in relation to one another.

Abstract: A lid for a container includes snap-fit hooks for interlocking engagement in complementing latching openings of an outwardly projecting flange of a jacket of the container, and stacking parts disposed on a lower side of the lid close to the periphery for form-fitting engagement in complementing stacking parts on an upper side of a further said lid, when the lids are stacked. The lower side of the lid and the upper side of the further lid have each a central region that forms a contact area via which compressive forces are transmissible in the presence of a contact between the contact areas of the lower side of the lid and the contact area of the upper side of the further lid.

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.

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.
