Folding box made of cardboard

1. A folding box made of cardboard, comprised of a folded blank which forms four lateral surfaces and a cover and base of a cuboid, the folded blank comprising:

four main folding lines which divide the blank into four main surfaces and a fastening surface, wherein

each of the main surfaces comprises a main surface segment, which forms a respective lateral surface of the cuboid after fastening of the fastening surface to the opposite main surface,

and multiple secondary folding lines, which run transversely to the main folding lines and each of which connects one of the main surface segments to a secondary surface segment, wherein

each of one or more of the secondary surface segments forms the cover and the base of the cuboid,

at least one of the secondary surface segments comprises a plurality of gaps between enclosing parallel webs and a folding line which runs over the secondary surface segment orthogonally to the webs and in which the secondary surface segment can be folded such that multiple receiving compartments that protrude from the base side are formed by the webs within the folding box,

the gaps are spaced by an outer strip from an edge of the blank and by an inner strip to a secondary folding line arranged between the main surface segment and the secondary surface segment comprising the gap,

the strips extend transversely to a main extension direction of the gaps and parallel to the secondary folding line,

the gaps are made wider towards the outer strip and have a serpentine shape, and

two auxiliary folding lines run along the connection of the strips with the webs.

2. The folding box according to claim 1 , wherein the inner strip at least partially forms the base and that the outer strip rests on an inner surface of one of the main surface segments defining a receiving space within the folding box.

3. The folding box according to claim 1 , wherein the folding line extends on the inner strip and the folding line divides the inner strip into a first inner strip segment and a second inner strip segment, wherein the first inner strip segment completely or partially forms the base and is wider than the second inner strip segment, which is connected, in particular glued or put together, with the first inner strip segment.

4. The folding box according to claim 1 , wherein two identical secondary surface segments each comprising the plurality of gaps are formed at the base side on opposite lateral surfaces of the cuboid.

5. The folding box according to claim 1 , further comprising a tear tab which is delimited by punching lines penetrating the cardboard only partially and which is provided on the main surface segments to surround the folding box.

6. The folding box according to claim 5 , wherein the tear tab is widened towards the base at a narrow front face side of the folding box formed by a main surface segment.

7. The folding box according to claim 5 , wherein the tear tab is formed to extend obliquely on opposite wide main surface segments interconnecting two narrower main surface segments forming the face side and the back side of the folding box, wherein a front narrower main surface segment between the base and the tear tab has a smaller extension than an opposite rear narrow main surface segment.

8. A packaging unit comprising the folding box according to claim 1 and blister packs containing toothbrushes, wherein each blister pack is received free-standingly in one of the receiving compartments of the folding box.
