  • Patent number: 6379034
    Abstract: A device for emptying a storage and transport container for liquids has a base frame, a pivot frame pivotably connected to the base frame, and a pivot drive connected to the pivot frame. The pivot frame has an initial low position and an upper pivot end position. The pivot drive can pivot the pivot frame from the initial low position into the upper pivot end position and from the upper pivot end position into the initial low position. The pivot frame receives the storage and transport container in the initial low position and secures the storage and transport container in the upper pivot end position. The upper pivot end position is the emptying position of the storage and transport container received on the pivot frame.

  • Patent number: 6058966
    Abstract: A plastic safety valve for containers, especially pallet containers with an internal container of plastic and an external jacket of metal for the transport and storage of liquids, is constructed as an automatic aerating and venting valve and is integrated into a lid or plug for sealing the filling and/or emptying opening or the aerating and/or venting opening of a container. The valve housing, which is constructed as a threaded plug and can be screwed into a corresponding threaded hole in a threaded cover or threaded plug, has a central hub supported by ribs, wherein the hub has a through-hole. The ribs extend outwardly in a star-like manner from the hub toward a ring-shaped shoulder. Air passage holes are formed between the ribs. An elastically constructed valve membrane of an aerating unit for opening and closing the air passage holes between the ribs is pushed from the inside onto the hub up to a shoulder of the hub.

  • Patent number: 5787623
    Abstract: Lettering plate (10) which is to be attached to the outside of a lattice jacket of a pallet container has a lower support edge (14) which is flanged or bevelled to the outside. The lower support edge abuts horizontal lattice rod (8) and reaches behind it. Two side edges (15, 16) of the lettering plate are flanged to the outside for resting on two vertical lattice rods (9). Openings (18) are provided in center section (17) of two side edges (15, 16) to hold horizontal lattice rod (8). The lettering plate (10) also has an upper edge (19) which is made as a clawed edge and which in the mounted state fits behind horizontal lattice rod (8) thereby resiliently bracing plate (10) against horizontal lattice rod (8). The horizontal lattice rod abuts the back of the plate in a middle plate section. The lower and upper edge (14, 15) have, depending on the size of lettering plate (10) and the grid division of the lattice jacket, one or more openings for holding one or more vertical lattice rods (9).

  • Patent number: 5680955
    Abstract: A pallet container (1) which may be used as a one-way of multi-way container to transport and store fluids, includes a blow molded fluid container (2) made of plastic which has a drain bottom (3) and a flexible inner liner (4) made of plastic foil or a composite metal-plastic foil. A pallet (5) which is designed as a floor pan (6) made of sheet metal or plastic which has a drain bottom (7) designed to serve as a form-fitted receptacle for the fluid container (2), as well as a metal grid casing (8) or sheet metal casing which encloses the fluid container (2). The fluid container (2) is sealed with a removable closure (12) which allows a simple and fast insertion of the inner liner (4) in the fluid container (2). To facilitate the insertion and removal of the inner liner into and/or from the fluid container, the same may be equipped with an integrally molded hinged cover, and it is possible to divide the fluid container into two halves after the blow molding.

  • Patent number: 5678688
    Abstract: The pallet container has a plastic inner container and a lattice jacket of vertical and horizontal lattice rods (9, 10) of metal. Stacking and transport safety is achieved by special design of the intersections (15) where the lattice rods (9, 10) are welded to one another. At these intersections (15) lattice rods (9, 10) are indented to form double-walled, cavity-like depressions (16). The depressions (16) have a center elevation (17). At each intersection (15) between longitudinal edges (18, 19) of center elevations (17) of depressions (16) of two lattice rods (9, 10) which lie at right angles on top of one another, this shaping of the lattice rods (9, 10) results in the formation of four contact points (20) which lie in one plane, each with a material accumulation which corresponds to four times the wall thickness of the lattice rods.
