Material cut from foldable material and container made from it

The invention relates to a material cut out of foldable material, such as cardboard, paper or the like, with folding lines and a container formed from this material cut out with a base and side walls.

Material cuts are known that can be folded along predetermined fold lines to form a container. In order for the resulting container to retain its shape, the material cut either has areas that are connected to one another using adhesive and/or slots or the like are provided in the material cut into which other parts of the material cut can be inserted.

The disadvantage of these known material cuts is that the material cut has a complicated shape and additional aids such as adhesive may be necessary to form the container.

Based on this state of the art, the object of the invention is to provide a material cut that has the greatest possible

• ··· ♦·

has a simple shape and a container made from it that can be easily formed from the material cut without any tools.

This problem is solved by the features of claims 1 and 9.

The material cut according to the invention can have a variety of simple shapes, for example it can be triangular or polygonal, in particular square. In the production of the material cut, no waste therefore occurs.

The material cut according to the invention is characterized by an arrangement of first, second and third fold lines as described in claim 1. This arrangement of the fold lines is extremely simple and can be printed on the material cut during production, for example.

Preferably, the fold lines are pre-stamped so that the folds required to form a container can be carried out more easily and precisely along the fold lines.

In another preferred embodiment, the middle area is square. This results in an attractively designed container with four side walls.

In order to make the material cut as simple as possible and to obtain the simplest and most symmetrical arrangement of the fold lines, the material cut corresponds to the shape of the central area and the edges of the central area run parallel to the edges of the material cut.

A container with side walls whose width increases from the bottom to the opening is attractively designed. Such a container can be made from a material cut according to claim 5.

Preferably, the third fold line then forms an angle bisector of an angle enclosed by the second fold lines assigned to a corner.

Further embodiments are the subject of claims 7 and 8.

A container with the features of claim 9 can be produced in a simple manner without any additional aids from the material cut out just by folding. No additional aids such as glue or staples are required. This container can be used in a variety of ways, for example as a wastepaper basket or garbage can. Such a container is advantageously used in the catering industry, because it can be thrown away together with its contents without harming the environment. By coating the material appropriately in a recyclable manner, the container can be used not only for paper, but also for wet waste, e.g. organic waste. It is very cheap to produce, because it essentially consists of just one piece of folded paper.

The individual material cut for a container can be stored in a very space-saving manner and can also be used as a note, for example. The containers can be stacked for storage.

To give the containers a nice appearance, the material cuts can be printed accordingly and thus used as advertising media.

The invention is described in detail below using exemplary embodiments with reference to the drawing. The drawing shows:

Figure 1 a first embodiment
a material cut according to the invention
,

Figure 2 shows the material cut from Figure 1 partially folded,

Figure 3 shows a container according to the invention,

which was folded from the material cut according to Figure 1,

Figures 4 and 5 show further examples of material cutting.

Figure 1 shows a first embodiment of a material blank 10 according to the invention, the outer peripheral shape of which is preferably square. The material blank 10 has first fold lines 12 which delimit a centrally arranged, angular middle region 14. In the preferred first embodiment, the middle region 14 is square.

From each corner 16 of the central region 14, second fold lines 18 and 20 extend in pairs to the edge 22 of the material cut 10. The second fold lines 18 and 20 enclose a corner region 24.

From each corner 16, a third fold line 26 located in the corner areas 24 extends to the edge 22 of the material cut 10.

In particular, in the case of a square material cut, the fold lines 12, 18, 20 and 26 are arranged symmetrically, as shown in Figure 1. The first fold lines 12 delimiting the central region 14 run parallel to the edge 22 of the material cut 10. The third fold lines 26 each form an angle bisector of one of the corners 16

associated second fold lines 18 and 19. Thus, the third fold lines 26 run on diagonals of the square material cut 10.

Regardless of the shape of the material cut, the corner regions 24 have an edge section 28 shown in Figures 2 and 3, which protrudes beyond an upper edge 34 of the side wall 30 when the corner region 24 is folded along the second and third fold lines 18, 20 and 26 and the associated mutual abutment of the second fold lines 18 and 20 assigned to a corner 16 of the central region 14 and when the folded corner region 24 is placed against one of the two adjacent container side walls 30 formed by the folding.

The formation of a container 36 from the material blank 10 is illustrated in Figures 2 and 3. The central region 14 forms the base of the resulting container 36. First, side regions 38 are folded up along the first fold lines 12. As can be seen in Figure 1, the side regions 38 are each delimited by one of the first fold lines 12, the second fold lines 20 and 18, which are each assigned to adjacent corners 16, and the edge 22 of the material blank 10. At the same time as the side regions 38 are folded up, the corner regions 24 are folded along the second and third fold lines 18, 20 and 26 into the interior 42 of the container 36 to be formed. The second fold lines 18 and 20 assigned to a corner 16 of the central region 14 come to rest against one another.

To prevent the container 36 formed in this way from unfolding again on its own, the folded corner areas 24 are placed against one of the adjacent side walls 30 and the edge section 28 protruding over the upper edge 34 of the side wall 30 is folded over the upper edge 34. This is

can be seen in Figure 3. The edge section 28 folded over the upper edge 34 then acts as a lock.

In the embodiment shown in Figures 2 and 3, the corner areas 24 are folded inwards and placed against one of the two adjacent side walls 30. Likewise, in another embodiment not shown, the corner areas 24 can be folded outwards and placed against one of the two adjacent side walls from the outside. The edge sections 28 are then folded over the upper edge 34 into the interior 42 of the container 36. Such a container has the advantage that the folded edge section 28 is kept folded in by the waste when the container 36 is filled, for example with waste. The container is then relatively stable when filled. In particular, such containers can be easily stacked, since in a stack the containers inserted from above keep the edge section of the lower containers folded in. The containers cannot then unfold on their own. The stack is stable.

In addition to a square material cut, as shown in the first exemplary embodiment, a large number of other material cuts are conceivable. Two further examples are shown in Figures 4 and 5. Figure 4 shows a pentagonal material cut 50, which also has a pentagonal central region 54. First fold lines 52, second fold lines 56 and third fold lines 58 are arranged according to the same principle as in the first exemplary embodiment with a square cut shown in Figure 1. With the pentagonal material cut 50, a container with five side walls can be formed analogously to the first exemplary embodiment (see Figures 2 and 3).

An embodiment shown in Figure 5 has a triangular material cut 60 with which a container with three side walls can be formed.

Again, the material blank 60 has a central area

64 and first fold lines 62, second fold lines 66 and 67 and third fold lines 68 and 69, which are basically arranged analogously to the first embodiment. In this embodiment, however, the second fold lines 66 and 67 assigned to adjacent corners 65 run parallel to one another. This causes the side walls of the container formed by the material cut 60 to run perpendicular to the base formed by the central region 64. In order that in this embodiment an edge section from a corner

65 associated second fold lines 66 and 67, protrudes over the upper edge of the side wall when the container is formed and can be folded in over the upper edge, further third fold lines 69 are provided, so that the corner areas 70 can be folded in several times.

In another embodiment, not shown, the width of the side areas decreases from the middle area to the edge of the material cut. Then, additional third fold lines must also be present so that an edge section of the corner areas protrudes over the top edge of the side wall when the container is formed and can be folded over it.

In all described embodiments, the folding lines
Preferably pre-embossed so that the material cut can be folded exactly along the fold lines when forming the container.
