DETAILED DESCRIPTION OF THE INVENTION

[0050] In FIGS. 1 to 6, a first embodiment of a container 1 adapted to receive an amount of wire 2, in particular welding wire, is shown.

[0051] Container 1 comprises a bottom plate 10, a top plate 12 and four posts 14 which extend between bottom plate 10 and top plate 12 and rigidly connect these with each other.

[0052] In this particular embodiment, both bottom plate 10 and top plate 14 have the form of a square, and posts 14 are arranged equally spaced from each other so that they also define a square, the dimensions of the square defined by posts 14 being smaller than the dimensions of the square defined by bottom plate 10 or top plate 12.

[0053] Bottom plate 10 is here provided with an inner opening 16 whose diameter is approximately equal to the inner diameter of a coil 18 formed from loops of wire 2. The footprint of coil 18 is shown in FIG. 4.

[0054] The coil can have an outer diameter of 700 mm and an inner diameter of 500 mm. Posts 14 can have a cross-section of 25*25 mm, 30*30 mm or 35*35 mm.

[0055] Top plate 12 is provided with a central opening 20 which here has a generally square shape. The opening is slightly smaller than the square defined by posts 14. Both the bottom plate 10 and the top plate 12 comprise attachment elements 22 which serve for mechanically connecting posts 14 to plates 10, 12.

[0056] In the first embodiment, attachment elements 22 are short portions of a tube with a cross section which corresponds to the shape of the cross section of posts 14, with the outer dimensions of attachment elements 22 corresponding to the inner dimensions of posts 14. Accordingly, posts 14, which are formed from hollow tubes, can be mechanically engaged by being pushed onto attachment elements 22.

[0057] Preferably, posts 14 are made from tubes having a square cross section. This provides an abutment surface for coil 18 which is much larger than the abutment surface which would be provided by tubes having a circular cross section.

[0058] Bottom plate 10 and top plate 14 are made from sheet metal with a thickness of approximately 2 mm. Tubes 14 are also formed from metal. The same is true for attachment elements 22 which can be welded to bottom plate 10 and top plate 12.

[0059] As can be seen in particular in FIGS. 1 and 3, a plurality of spacer blocks 24 are arranged underneath bottom plate 10. Spacer blocks 24 can be made from wood or from plastic and have a dual function. On the one hand, they allow easy handling of the container by means of a forklift. On the other hand, they insolate container 1 from the ground which is helpful in as much an electrical tension is applied to wire 2 in case the wire is welding wire.

[0060] Blocks 24 can be connected to bottom plate 10 with attachment screws 26 which extend through the bottom plate.

[0061] Other frame formed from bottom plate 10, top plate 12 and posts 14 defines a receiving space for coil 18. In order to prevent dirt from entering into the container, a cardboard box 28 is provided as an outer cover. In addition, a plastic bag (not shown in FIGS. 1 to 4) can be placed within the container before the wire is being inserted.

[0062] FIGS. 7 to 11 show a second embodiment of the wire container. For the elements known from the first embodiment, the same reference numerals are used, and reference is made to the above comments.

[0063] The main difference between the embodiment shown in FIGS. 5 to 11 and the first embodiment is in the structure of the attachment elements 22. In the second embodiment, the attachment elements 22 are in the form of short lugs which are welded (please see weld seam 22) to posts 14.

[0064] Each attachment element 22 is here provided with an opening through which a screw can extend. For attachment elements 22 associated with the lower end of each post, attachment screw 26 can be used which is also used for attaching spacer blocks 24 to bottom plate 10. For the attachment elements 22 associated with the upper end of each post 14, separate attachment screws 27 are used for firmly connecting attachment element 22 to top plate 12.

[0065] A plastic bag 30 (please see in particular FIG. 10) can be used to prevent humidity from entering into the interior of container 1. Plastic bag 30 is arranged outside of the frame formed by plates 10, 12 and posts 14, and within cardboard box 28.

[0066] Both bottom plate 10 and top plate 12 comprise receiving openings 32 adapted in size and shape to receive the ends of posts 14 (please see in particular FIGS. 8 and 11). Attachment elements 22 are connected to posts 14 in a small distance from the end of the posts, this distance being approximately the wall thickness of the bottom plate and the top plate. By placing the ends of posts 14 not flush on plates 10, 12 but by placing them recessed “outside” the space which receives the wire, it is prevented that wire is being pinched between the ends of the posts and the respective plate.

[0067] FIG. 12 shows a wire container according to a third embodiment, which is similar to the first embodiment but is not provided with spacer blocks. Rather, a lifting strap 40 is provided which extends from above the container along a sidewall, underneath the bottom plate 10, and along an opposite sidewall upwardly.

[0068] In FIGS. 13 and 14, a container according to a fourth embodiment is shown. For the elements known from the previous embodiments, the same reference numerals are being used, and reference is made to the above comments.

[0069] The difference between the fourth embodiment and the other embodiments is the configuration of attachment elements 22.

[0070] In the fourth embodiment, attachment elements 22 consist of an attachment lug 22a, and a projection 22b adapted in shape and size to engage to the interior of posts 14. Attachment lugs 22a are connected to bottom plate 10 and top plate 12 by means of attachment screws 26, 27.

[0071] As can be seen in FIG. 14, attachment lugs 22 here have a rectangular shape.

[0072] In FIGS. 15 to 19, a container according to a fifth embodiment is shown.

[0073] For the elements known from earlier embodiments, the same reference numerals are used and reference is made to the above comments.

[0074] In the fifth embodiment, both the bottom plate 10 and top plate 12 are formed from sheet metal which is thinner than in the previous embodiments. While in the previous embodiments, sheet metal with a thickness of approximately 2 mm was used, the fifth embodiment uses sheet metal with a thickness of approximately 1 mm.

[0075] Attachment elements 22 are here formed from portions of the sheet metal which are cut and bent upwardly or downwardly so that two parallel wings 23 are created which are adapted to engage into the interior of posts 14.

[0076] The outer edge of plates 10, 12 can be bent so as to avoid sharp edges, and the inner circumference of central opening 20 of top plate 12 can also be bent.

[0077] Central opening 20 is here formed with an octagonal shape.

[0078] A container according to a sixth embodiment is shown in FIGS. 20 to 22. The difference over the fifth embodiment is that in the sixth embodiment, bottom plate 10 is also provided with a central opening which has the same octagonal shape as central opening 20 of top plate 12.

[0079] In all embodiments, posts 14 can easily be separated from bottom plate 10 and top plate 12. In some embodiments, posts 22 can simply be pulled from attachment elements 22 while in other embodiments, attachment screws 26, 27 have to be removed. In any case, the frame of container 1 can be disassembled very quickly so that its components can be stored in a space saving manner and recycled.
