For better clarity is in the illustration according to 1 the lid part 4 away. The longitudinal side parts 2 be by means of further explained below connectors 7 at the bottom part 1 attached.

The bottom part 1 with the bottom plate 10 , the longitudinal and transverse side parts 2 . 3 and the lid part 4 are all made of plywood panels, OSB wood panels of a thickness of for example 15 mm or straw fiber panels of a thickness of 12.2 mm, for example.

The bottom part 1 includes in addition to the already mentioned bottom plate 10 below the bottom plate 10 several skids 12 which allow underrunning and lifting and transporting by means of conventional forklift trucks and / or pallet trucks. The runners 12 may be made from sections of a profile made from the continuous or discontinuous extrusion of recycled plastic material based on films or mixed fractions of polyolefins such as polyethylene or polypropylene, optionally with the addition of stabilizers, lubricants, pigments or fillers. These are, for example, ground fractions of plastic waste from the collection of recyclables. The runners 12 may be partially or fully clad with wood panels.

For mounting the longitudinal side parts 2 are plug connections 7 consisting of bolts 11 and associated mounting holes 23 provided when inserting the bolt 11 in the mounting holes 23 have a common axis A.

As in particular from the 1 can be seen, has each longitudinal side part 2 in its corner inside a groove profile 20 for example, U-shaped cross-sectional configuration, wherein the grooves of opposite longitudinal side parts 2 are facing each other with their groove opening. Also the groove profiles 20 are made of the plastic material, from which also the already explained skids 12 be made.

At the bottom of the groove profiles 20 are the mounting holes 23 intended. Due to the selected dimensioning of the bolts 11 and the receiving bore 23 and an orientation of the A axis defining bolt 11 at an angle α to the bottom part 1 It is possible to use the longitudinal side parts in the 2 shown manner at an angle α corresponding mounting angle of less than 90 ° to the bottom part 1 , here approximately at an angle α of 83 °, to sit on the bottom part and in this case the bolt 11 into the receiving hole 23 in the groove profile 20 plug in, leaving bolts 11 and receiving bore 23 together the axis A at the mounting angle α to the bottom part 1 exhibit.

Due to the selected angular orientation of the bolts 11 and a certain bending elasticity of the bolts 11 It is thus possible, the longitudinal side parts 2 for the purpose of mounting in the 4 shown manner at a mounting angle α of less than 90 ° to the bottom part 1 , here correspondingly at an angle α of 83 °, on the bottom part 1 put on and this the bolts 11 into the receiving hole 23 insert.

The following can be the lateral parts 3 like from the 1 visible in the groove profiles 20 be inserted, thereby simultaneously the longitudinal side parts in their use angle β of 90 ° relative to the bottom part 1 be erected, against the elastic resistance in the receiving bores 23 plugged in bolts 11 , In this illustrated position according to 1 in which the longitudinal side parts 2 at an angle of 90 ° to the bottom part 1 are located, that is in the so-called use angle, practice the longitudinal side parts 2 on the groove profiles a clamping force F on the inserted transverse side parts 3 out, which ensures that the longitudinal side parts 2 and lateral parts 3 remain in this orientation, even if the entrusted with the assembly person the longitudinal side parts 2 or lateral parts 3 raising.

The in the groove profile 20 for receiving the edge 300 of the lateral part 3 provided groove 200 can according to 6a consistently over the entire longitudinal extension of the groove profile 20 run and the transverse side part 3 Accordingly, has a rectangular outline.

Alternatively, according to 6b also be provided that the groove 200 in its upper end area 201 closed and therefore from the upper end of the groove profile 20 is not accessible. In this case, the transverse side part 3 in its upper corner with a corresponding notch 301 provided so that the groove profile 20 in the angle of use the lateral part 3 also overlaps the upper side and an unwanted sliding out of the transverse side part 3 out of the groove 20 reliably prevented.

Subsequently, the lid part 4 be placed on the closure of the transport box and possibly fixed.

Similarly, the disassembly of the transport box, by first the lid part 4 removed, below the transverse side parts 3 from the groove profiles 20 pulled out and then the longitudinal side parts 2 with their bolts 11 from the mounting holes 23 be pulled out.

The transport box can then be folded to save space, see 5 ,

As further from the 1 and 3 As can be seen, the groove profiles extend 20 the longitudinal side parts 2 in the assembled state continuously from the bottom plate 10 of the bottom part 1 to the lid part 4 and can therefore have loads on the lid part 4 rest, in the bottom part 1 initiate, so that the transport box reaches a high stacking capacity, even under load.

In addition, also how can 7 visible, in the area of the transverse side parts 3 , preferably in the middle region, a vertically from the bottom part 1 to the lid part 4 extending support strut 30 be provided, which in turn further loads on the cover part 4 pick up and into the bottom part 1 can accommodate to increase the stackability. Also the support strut 30 can be topside with a bolt 31 and underside with a bolt 32 for engaging in the locking element 5 or the bottom part 1 be provided. Other engagement elements are conceivable.

Moreover, in the embodiment according to 7 the transverse side part 3 formed in two parts with a horizontal division, giving it two by reference numbers 3a . 3b designated parts is formed. In this case, vorla gene, the support strut 30 for example, at the bottom 3a pivotally mount about a rotation axis D, so that the support strut 30 can be folded in a space-saving manner along the horizontal dividing line during disassembly of the transport box and during assembly of the transport box as from 1 can be rotated by 90 ° in its vertical orientation.

As in particular from the 4a In addition, the cover part can, moreover, be seen 4 at its bottom with a profile 40 be equipped, which in the disassembled state of the transport box as shown in 4a is placed facing up and into the room 100 a stacked bottom part of the next transport box engages and thus serves as anti-slip.

Finally, it is proposed, in order to increase the connection strength between the longitudinal and transverse side parts again openable closure means 6 For example, reopenable cable ties through corresponding holes 60 in the connecting region between two transverse edge adjoining longitudinal and transverse side parts 2 . 3 to install.
