1 shows a blank made, for example, of corrugated cardboard, Fine corrugated cardboard or the like can be punched out. additionally 1 shows those to be formed later in the blank or also identical folding lines 2 in dashed lines Lines. Approximately in the middle of the cut is the see rectangular bottom 1 of the box. He is at everyone Pages delimited by fold lines 2 by dashed lines Lines are shown. On the long sides of the bottom 1 are each followed by two sections 3, 4, which in turn are separated from each other by fold lines 5. The form two sections 3, 4 in the folded state the side walls of the box, with the outside cut lying sections 4 the inner walls and between them and the bottom 1 lying sections 3 the outer walls of the Form side walls. In the area of the free outer edges 6 sections 4 contain two narrow elongated Insert tabs 7, in the longitudinal direction of the box seen, are arranged in the same places as that slot-like openings 8 along the side edges of the Soil 1 are arranged.

At the separation point defined by the fold lines 5 between the outer wall 3 and the inner wall 4 is also a longitudinal slot-like opening 9 provided that with the box erected at the top edge the side wall lies.

On the lower side in FIG. 1, the inner wall 4 forming sections of the side walls a section 10 articulated from the inner wall 4 by a fold line 11 Cut. The one running in the longitudinal direction of the blank Dimension 12 of this section 10 corresponds to half Transverse extent of the bottom 1, in other words the width the box.

Now for the description of the ones attached to floor 1 in Parts of the blank adjoining it in the longitudinal direction. On the upper short edge of the bottom 1 in FIG. 1 is a Section 13 attached separately by a fold line 2. On this section 13 is approximately the same size Section 14, again separated by a fold line 15. The dimension of the measured in the longitudinal direction of the blank Sections 13 and 14 are the same and correspond to those in the transverse direction measured dimension of sections 3 and 4. This Dimension 16 represents the height of the folding box.

Along fold line 15 between sections 13 and 14 a slot-like opening 17 is punched out. With the two remaining edges of section 13 is by a Fold line 18 separated, each a quarter-circular section 19 connected. The sections 13, 14, 19 together form the Front wall of the box. At the end facing away from the bottom 1 of section 14, an insertion tab 20 is formed, which in their arrangement of the slot-like opening 21 along the Dividing lines between the floor 1 and the section 13 corresponds.

Opposite the sections forming the front wall connects to the bottom 1 a section 22, which later forms the back wall. On the two side edges of the rear wall 22 is hinged into a section 23 which is a lateral one Limiting the rear wall 22 forms.

On the side facing away from the connecting line with the floor 1 the back wall 22 is separated by a fold line 24, the Lid 25 hinged. The lid 25 has in the area of its two longitudinal edges 26 each provided with an undercut Tab 27 on.

In the area of its free end, the cover 25 contains one Insert tab 28.

The cut is symmetrical to one in the longitudinal direction line running through it.

The blank shown and described in Fig. 1 can be erected and folded as follows to form the To produce a box. First, the back wall 22 is around her Connection line with the bottom 1 folded by 90 °, and then the two sections 23 also by 90 ° folded inside. The lid can then also be around Line 24 can be folded. Then the sector sections 19 folded inwards by 90 °, and section 14 folded by 180 ° so that it is on the outside of the front wall comes to lie inside. The tab 20 is in the Slot 21 inserted. Then the front wall is around the Connection line with floor 1 folded up. It the state arises as shown in FIG. 2. Of course, the order of folding the front wall and Interchangeable back wall.

Now the side walls are folded. For this, the Sections 3 folded up and sections 4 after Inside. Before or at the same time, the two sections 10 are folded in the opposite direction, d. H. of the state of the flat cut down, like this is indicated on the left in Fig. 2. Sections 4 are around the top edges of sections 23 and 19 into the Indented inside of the box. The insertion tabs 7 are pressed into the slots 8. This will make the Box locked. The box is now complete and can be filled from the open top. The Lid 25 can then be closed. To do this, he will look at the Connection line 22 folded around. The insertion tabs 27 are inserted into the slots 9, see Fig. 1. Since the Insert tabs 27 are slightly undercut, this leads to a kind of locking of the lid with the side walls. The Insert tab 28 at the end of the lid can in the slot 17th be inserted so that the hinged front wall 13th is locked.

The lid 25 contains a further fold line 29, see Fig. 2, which is arranged approximately shortly before the insertion tabs 27 is. The front part 30 of the Lid 25 can be opened around, as shown schematically in Fig. 3 is shown. The insertion tab 28 can in a slot-like opening 31 are inserted in the cover 25.
