Patent number: 8408413Abstract: 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.Type: GrantFiled: June 21, 2005Date of Patent: April 2, 2013Assignee: Mauser Werke GmbH & Co.

Patent number: 7908980Abstract: 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.Type: GrantFiled: December 5, 2006Date of Patent: March 22, 2011Assignee: Mauser-Werke GmbHInventors: Klaus-Peter Schmidt, Detlev Weyrauch, Dietmar Przytulla, Ernst Wurzer

Patent number: 7296374Abstract: An identification plate for a pallet container includes a plate body for placement upon a lattice frame of a pallet container. The plate body has an upper edge, which is bent rearwards at a first angle for attachment to an upper horizontal rod of the lattice frame, a lower edge, which is bent rearwards at the first angle for attachment to a lower horizontal rod of the lattice frame, and opposite lateral edges extending between the upper and lower edges and bent rearwards at a second angle which is greater than the first angle. Each of the lateral edges ends at its rear in a rolled edge and is formed with terminal recesses for receiving the upper and lower horizontal rods. The rolled edge is hereby sized to project with its ends in a rod-like manner into the recesses to engage behind the upper and lower horizontal rods.Type: GrantFiled: August 18, 2006Date of Patent: November 20, 2007Assignee: Mauser-Werke GmbH & Co.

Patent number: 7040501Abstract: This invention relates to a cylindrical, blow-molded lidded barrel (wide-mouthed drum) with a barrel lid and tension-ring closure. Previously known lidded barrels have comparatively little ability to withstand falls and are therefore not well-suited for handling liquids. Owing to the special configuration of the barrel lid and the barrel mouth edges as well as by a special matching of the individual components to one another, the lidded barrel according to the invention can be manipulated in the filled state with the same barrel-gripping tool (parrot's beak), ans is universally employed and in industrial use for modern plastic L-ring bung barrels or normal steel bung barrels. By improving the strength of the lidded barrel when it is dropped, the barrel is also made especially well-suited for handling liquids since it remains liquidtight even when dumped or dropped from great heights.Type: GrantFiled: March 14, 2000Date of Patent: May 9, 2006Assignee: Mauser-Werke GmbH & Co. KGInventor: Dietmar Przytulla

Patent number: 7042695Abstract: The invention relates to a multi-layer plastic container (10) for the storage and transport of materials in particular with an explosion risk, comprising at least two layers of plastic, whereby the inner layer (14) is not electrically conducting and the outer layer (12) is electrically conducting. According to the invention, an electrostatic charging of the plastic container or/and the inner filled material with a risk of explosion may be avoided, whereby a permanent electrical connection between the inner packed material and the base on which the plastic container (10) is mounted is provided which guarantees a secure discharge of electrostatic charging of the container body or the packed material to the base.Type: GrantFiled: April 23, 2003Date of Patent: May 9, 2006Assignee: Mauser-Werke GmbH & Co.
