Definitions

• the invention relates to a collapsible transport container with a grand plate designed as a pallet, four side walls and a lid, the parts of which are connected to one another by means of clips.
• a collapsible pallet container which has a base plate in the manner of a pallet and whose four side parts projecting from this pallet approximately vertically are connected to one another, to the base plate and to a cover by means of resilient clips.
• the pallet container "can easily be assembled or disassembled by one person, so that it offers the possibility of being transported in the collapsed state. It can be equipped with a fixed inner lining that facilitates the transport and storage of fluid Since the inner lining is fixed and non-detachable, this container must also be cleaned or disposed of after use and the same problems as with drums and tanks arise in this regard.
• the invention has for its object to improve the collapsible transport container so that it is suitable for the transport and storage of liquids and which is frequently reusable without the need for cleaning work.
• the collapsible transport container is provided according to the invention with a removable lining in the form of a bag.
• This bag has closable inlet / outlet and outlet openings, the outlet opening in an area near the base plate is arranged.
• One of the side walls has an opening or a removal opening in the area near the base plate, the opening or removal opening being opposite the outlet opening of the bag.
• the liquids, powders or granules to be transported or stored are filled into the bag through the inlet opening. They only come into contact with the inside of the bag, so that the base plate, the side walls or the lid are not contaminated. Since this bag is removable, it is possible to clean or dispose of the bag after the transport container has been emptied, the base plate, the side walls and the lid being available for reuse in any case. Since, by adapting the bag to the interior of the transport container, the forces exerted on the transport goods on the transport container are absorbed by the side walls and the base plate, it is possible to make the bag relatively thin-walled, thereby saving material and waste.
• the outlet opening which is arranged opposite an opening in a side wall in the area near the base plate, allows the container to be emptied standing on the base plate.
• the handling of the transport container is greatly simplified.
• the clips are attached on the outside and engage in slots in such a way that they pull the edge of the corresponding side wall into the associated fold, which represents a stop for the side wall. This arrangement ensures that the transport container retains its stability even in the partially or completely emptied state.
• the bag is designed to be oxygen-tight, waterproof, acid-resistant or alkali-resistant in accordance with the requirements of the transport goods.
• the transport container is characterized used for most water-containing products with low acidic or alkaline properties in a Temperaturbe ⁇ ranging from -10 "C to +80 * C. If the Trans ⁇ port container transporting coarse granules, the bag may also have a layer of A particularly inexpensive and easy-to-manufacture bag type has a layer of low-density polyethylene as a contact layer with the goods to be transported. If there are different demands on the properties of the bag, it is also possible to that it is built up in multiple layers.
• the bag is provided with an outlet nozzle, so that the connection of a removal aid is possible without difficulty.
• Placing the bag in a fiberboard cassette improves the insulation of the bag and its content towards the environment.
• the fiberboard cassette which can consist of corrugated cardboard, protects the bag in its folded state from being filled.
• the outlet connector is fastened to a movable tab of the fiberboard cassette in such a way that the tab introduces the outlet connector into the opening in the side wall during filling.
• a reinforcing plate which can be arranged in the area of the opening through the side wall, the outlet opening can be fixed and an improved force absorption can be brought about in this area.
• the reinforcement plate can also be used as a spacer element in order to prevent the outlet connector from protruding beyond the outer surface of the side wall.

• the transport container 1 which is preferably made of wood, has a square base plate 2, on the underside of which parallel studs 4 are arranged such that the base plate 2 can be lifted or moved in the manner of a pallet by a pallet or pallet truck.
• Side walls 6 protrude approximately at right angles from the top of the base plate 2 and are detachably connected to one another and to the base plate 2 by means of resilient clamps 8.
• the transport container ⁇ 1 is closed at the top with a lid 10.
• the base plate 2 has a fold 14 on its top all around, on each edge 12, the extent of which fold parallel to the plate surface is equal to the thickness of the side walls 6.
• the fold 14 forms a stop against which each of the side walls abuts.
• the cover 10 also has a circumferential fold which forms a stop for the side walls 6.
• Each of the side walls 6 is blunt on three side edges 16 and provided with a fold 20 on the fourth side edge 18.
• the extent of the fold 20 parallel to the surface of the side wall 6 is equal to the thickness "of the side wall 6 abutting into this fold 20.
• Those for connecting the base plate 2 to the side walls 6, the side walls 6 to one another and the side walls 6 with the resilient clamps 8 used with the cover 10 are made from elbow-like spring steel strips. In the assembled state of the transport container, they are placed around the edges of the transport container 1 and in this state they have a right angle between their two legs 22, 24. So that the clamps clamp the transport container 1 together, they have an angle between their legs 22 and 24 in the disassembled state which is somewhat less than 90 * .
• each leg 22, 24 the brackets 8 have a projection that is bent toward the interior of the container. With this projection, the springs 8 engage in straight slots 26 which are milled into the outer sides of the side walls 6, the underside of the base plate 2 and the upper side of the cover 10. The slots 26 extend parallel to the edges 12, 16, 18 of the base plate 2, the side walls 6 and the cover 10 at a distance of 90 mm.
• the length of the slots 26 is greater than the width of the clamps 8 and their distance from their respective plate edge 12, 16, 18 is independent of whether a fold is provided on the edge or not. If the plate 28, the side walls 6 and the cover are 18 mm thick, the distance of the slots from the respective edge is 90 mm.
• the clips engaging in the slots then have two legs which are of different lengths, one leg 24 being 90 mm long according to the distance of the slots 26 from the edges 12, 16, 18 and the other leg 22 being 103 mm long. This ensures that when the transport container 1 is disassembled, the side walls 6 laid flat on the plate 28 and the cover 10 on the base plate with clips 8 can be attached. For this purpose, the inside of the cover must face upwards so that the clamps 8 can engage in the fold. It should be noted that each fold protrudes so deeply into the corresponding plate that the remaining material thickness is equal to the length of the longer leg 22 minus the shorter leg 24. Here this material thickness is 13 mm, so that each fold is 5 mm deep.
