Definitions

  • the present invention relates to a transport container assembly, a so-called pallet container, comprising a pallet and an associated container secured to the top side thereof, especially intended for the transportation and storage of bulk material, such as plastic pellets and the like.
  • Containers of the above-defined type are utilized as disposable containers, i.e., they are not returned and reused. It is therefore obvious that such containers should be as inexpensive as possible to manufacture, yet should be rugged enough not to become damaged under the stresses to which they are subjected during use. It should be noted that the stresses are relatively great, since such containers often are utilized to contain 1000 kg real weight.
  • the pallet utilized in such pallet containers is normally a four-way pallet, i.e., the pallet has openings on four sides for convenient access from all sides for the fork of a fork truck. Hitherto, so-called Eruopallets have most often been utilized, i.e., pallets composed of two wooden platforms with intermediate spacer blocks.
  • the container or drum part of the pallet container has usually been made of double-sided corrugated cardboard. This is a relatively inexpensive and strong material, but has definite limitations in regard to the shape of container possible. Double-sided corrugated cardboard cannot be shaped along a curved line, but must be bent and broken along straight lines.
  • the object of the present invention is to provide an inexpensive method of producing a pallet container wherein the above drawbacks are avoided and which is efficient and practical in use, which has a desirable shape from the point of view of force distribution, which is more moisture-resistant than the previously used pallet containers of this type, and has a great thermic insulation capacity.
  • a method of producing a pallet container comprising a pallet and a tubular container secured to the top side of the pallet, especially intended for the transportation and storage of bulk materials such as plastic pellets or the like is characterized in that a pallet having a circular neck on the top surface thereof is secured with its top side to the end of a cylindrical winding mandrel having a diameter corresponding to the diameter of the neck, and that one-sided corrugated cardboard to which glue has been applied is wound in several plies on the mandrel and the neck of the pallet, so that the plies become glued to each other and to the neck.
  • a further development of the method of the invention is characterized in that a watertight sack of a suitable material, e.g., plastic, is drawn over the mandrel before the pallet is attached to the end of the mandrel and that the wound shell is glued to the sack.
  • a suitable material e.g., plastic
  • the pallet container produced by the invention consists of a pallet 1 which preferably is molded of expanded polystyrene.
  • the pallet consists of a solid plate 2 with legs extending downwardly from the bottom surface thereof, in the illustrated example three legs 3, arranged so that two openings 4 are provided for inserting the fork of a conventional fork truck. To avoid unnecessary amounts of force, the corners of the pallet are bevelled off.
  • Secured to the top side of the pallet is a circular shell 5 made of windings of sheet- formed material.
  • the top opening of the container is closed by a lid 6.
  • the container is filled with bulk goods 7, e.g., 1000 kg of plastic granules.
  • FIG. 2 A practical embodiment of the pallet container may be seen more clearly in Figures 2 and 3.
  • an upturning circular neck 8 is provided, to which the shell 5 is secured.
  • the shell consists of several plies of one-sided corrugated cardboard (seen best in Figure 3).
  • the neck 8 has a corrugated periphery 9 corresponding to the corrugations 10 on the inner corrugated ply 11 of the shell. Optimum joining of the shell 5 to the neck 8 is thereby obtained.
  • the top surface of the pallet may have a sloping edge 12. Inside the container, a bag or sack 13 of plastic may be glued.
  • Figure 4 shows how the pallet container of the invention is produced.
  • the sack 13 is drawn over the winding mandrel 14 on a winding machine 15.
  • the outer end of the mandrel is provided with a pin 16 which fits snugly inside a hole 17 in the top surface of the pallet 1.
  • the mandrel 14 has the same diameter as the neck 8 of the pallet 1.
  • a glue applicator 19 Disposed between the winding mandrel 14 and the roll 18 is a glue applicator 19 for applying glue to the sheet material 20 on the inner surface of the material facing toward the mandrel.
  • the one-sided corrugated cardboard is wound with the corrugated side facing inwardly toward the mandrel.
  • the first ply of the shell 5 must be without glue on the initial portion thereof which will be in contact with the mandrel, being provided with glue only on the portion thereof which lies around the neck 8.
  • the mandrel can either be made to be collapsible, or one can introduce air into the mandrel which penetrates through small jet openings in the mandrel to pass out between the mandrel and the wound shell.
