Definitions

  • the present patent application relates to a method for producing a transport packaging for calcium carbide for use in metered small quantities.
  • DE-C-2 033 160 discloses a device for metering moisture-sensitive solids such as calcium carbide, in which several containers are used which are square in their upper part and tapered at their lower end, these containers being used simultaneously for transport and storage serve the calcium carbide and each container holds about 1000 kg of calcium carbide.
  • this device does not allow a sufficiently precise metering of small quantities, for example of 5 kg, since the tare weight resting on its pressure cells is too large in relation to it.
  • a packaging for granular products in bags which consists of a multi-layer corrugated cardboard container attached to a pallet.
  • the bags are placed in the container and stacked beyond the height of its side walls.
  • a closure consisting of multilayer corrugated cardboard is pushed over, which comprises a flat upper part and downward-facing side walls and which partially engages around the side walls of the container.
  • a shrinkable plastic film is placed around the top and side walls of the closure and around the side walls of the container and shrunk in a shrink oven at a temperature of about 150 ° C.
  • the container according to US-A-1 875 497 is constructed from four side walls and four upper and lower closure flaps, which are all connected to one another. After the lower flaps have been closed, a sack lying against its side walls can be inserted into the container, which can be filled with bulk material up to the height of the side walls. However, after the lower flaps have been closed, a cylindrical insert affecting the side walls can also be introduced, while in the area of the corners of the container a reinforcement tube is inserted which touches both the cylindrical insert and the side walls.
  • the container for handling loose material according to US-A-3 073 500 consists of an inner and an outer box which have been pushed into one another with the interposition of corner reinforcement angles.
  • the boxes, which are spaced apart, are attached to a pallet. After filling the inner box with the loose material, the upper areas of the four sides of the inner box are first folded inwards and then the upper areas of the outer box designed as lids are closed.
  • a pallet which consists of lower and upper ribs which are arranged with blocks spaced vertically apart. A plurality of ribs constructed in this way and spaced apart from one another are connected to one another by cross bars. A rectangular container is fastened to this pallet and can be closed with a lid. Containers and lids are encompassed several times by steel strips in the transverse direction.
  • the coolers are stacked on a pallet between a flat bottom and a lid made of cardboard or plastic and strapped with metal straps.
  • the coolers stacked in this way are completely encased in a shrink film.
  • the shrink film is shrunk by treatment with hot air, which holds the cooler stack in place and seals the coolers.
  • a polyethylene tube produced by a combined extrusion blow molding process is cut open with a wall thickness of approximately 0.1 mm, folded in a special form, welded in the transverse direction and cut to form sacks.
  • Such a sack is brought over an essentially rectangular pallet load. After the pallet load is covered with the sack in this way, it is briefly exposed to temperatures of around 200 ° C in an oven, whereby the sack shrinks.
  • This is achieved according to the invention in that a large number of sealed bags made of plastic film, preferably polyethylene film, filled with a predetermined amount of calcium carbide, with a thickness of 0.05 to 0.4 mm and a mass per unit area of 50 to 400 g / m 2 packed in several layers one above the other in a box fastened on a pallet, made of multiple cardboard and then closing the box; that a ring insert is inserted in the box, which lies against the vertical inner walls of the box with the exception of the areas of its corners; that in each corner of the box there is a pipe section extending from its bottom to its lid, the pipe sections being affected by the ring insert while stabilizing their position; that the box has outer bottom and lid closure flaps which completely overlap each other; that a covering grate is
  • the method according to the invention can also be designed by strapping the closed box, the cover grate and the pallet twice in the longitudinal direction and / or in the transverse direction with a band.
  • a single-use pallet which is preferably designed as a two-way pallet (see DIN 15 145, August 1977), made of wood, which together with the box and the cover grate after removal of the calcium carbide at the point of use, for example by burning , is easy to remove.
  • the filling of the calcium carbide into bags made of plastic film and their gas-tight sealing by welding is advantageously carried out in the method according to the invention with a correspondingly constructed machine using a plastic tube.
  • the mechanical handling on the one hand prevents moisture from getting into the bags and on the other hand guarantees precise dosing.
  • the stackability of the boxes is increased in that pipe sections extending from the floor to the ceiling are arranged in their four corners.
  • the strength of the walls of the box is increased in the method according to the invention on the one hand and the position of the pipe sections is stabilized on the other hand.
  • a box 2 made up of several layers of cardboard 1 is firmly connected to a recessed two-way flat pallet 3 (see DIN 15 145, August 1977).
  • a ring insert 4 is inserted into the box 2, which lies against the vertical inner walls of the box 2 - except for the area of its corners.
  • In the corners of the box 2 are each tube sections 5, which run from the floor to the top of the box 2. In the corner areas, the ring insert 4 touches the pipe sections 5, whereby their position is stabilized.
  • a cover grate 6 rests on the closed box 2.
  • the pallet 3, the box 2 and the cover grating 6 are strapped twice in the longitudinal direction with a steel band 7 each.
  • a ring insert made of corrugated cardboard and four tube sections made of cardboard are set at the corners.
  • the box is glued to a return two-way flat pallet.
  • 200 polyethylene bags (length 36.5 cm, width 28.5 cm, film thickness 0.1 mm), each filled with 5 kg calcium carbide and sealed gas-tight, are packed in several layers one above the other in the box. After closing the box, a cover grate is placed on its top.
  • Cover grating, box and pallet are strapped twice in the longitudinal direction and once in the transverse direction with steel tape (thickness 2 mm, width 20 mm) before they are covered with a tube made of shrink film (thickness 0.2 mm). After the hose has been welded on, it is blown with warm air at 70 ° C and shrunk as a result.
