Abstract: 1. Box made of foldable material, comprising: box part, the box part having a box front wall, a box rear wall, box side walls and a box base, a lid part having a lid front wall, a lid rear wall, lid side walls and a lid top side, and a collar (10) having a collar front wall (12) provided with a cut-out section (20) and collar side walls (14), the lid part being linked with the lid rear wall on the box rear wall, the collar (10) being arranged in the box part and the collar front wall (12) projecting at least partly out of the box part, characterized in that the rim (16) of the collar front wall (12) remaining on the left and right next to the cut-out section (20) is so narrow that it projects forward due to the rigidity of the foldable material, in particular in its upper area. 2. Box according to claim 1, characterized in that the lid is held essentially in the closed state by the friction between the forward-projecting rims (16) and the inside of the lid front wall. 3. Box according to one of claims 1 or 2, characterized in that in each case one or more of the longitudinal edges of the box part, of the lid part and of the collar are rounded off or chamfered. 4. Box according to one of claims 1 to 3, characterized in that the foldable material is paper or cardboard. 5. Box according to claim 4, characterized in that the foldable material is shortgrain paper or shortgrain cardboard. 6. Box according to claim 5, characterized in that one or more of the longitudinal edges of the box are rounded off or chamfered and the chamfering or the rounding of the longitudinal edges of the box and lid parts is formed by scoring lines and the chamfering or the rounding of the collar (10) by grooves. 7. Box according to one of claims 1 to 6, characterized in that the inside of the lid front wall is formed by a strengthening field (30) with at least one recess (32) which is shaped such that upon closure of the lid part it interacts with the edge (18) of a collar rim (16) so that in the closed state of the box at least a part of the collar rim (16) comes to rest between the outside of the lid front wall and the strengthening field (30). 8. Box according to claim 7, characterized in that the recess(es) (32) is/are essentially v-shaped, the edges of the recess(es) (32) is/are curved, the deepest point of the recess(es) (32) lies/lie roughly at midheight of the strengthening field (30) and the recess(es) (32) extends/extend from the top edge (38) of the strengthening field (30) over approximately 50 to 90%, in particular 60 to 70%, of the height of the strengthening field (30). 9. Box according to one of claims 7 or 8, characterized in that one or both top corner(s) (34) of the strengthening field (30) is/are provided with an embossed area (36). 10. Box according to claim 9, characterized in that the embossed area(s) extends/extend inwards from the top edge (38) of the strengthening field (30) and the top end(s) of the edges of the recess(es) (32) to the strengthening field (30). 11. Box according to one of claims 9 or 10, characterized in that the embossed area (36) approximately corresponds to the thickness of the foldable material. 12. Collar (10) made of foldable material which has a collar front wall (12) provided with a cut-out section (20) and collar side walls (14) characterized in that the rim (16) of the collar front wall (12) remaining on the left and right next to the cut-out section (20) is so narrow that, when inserted into a box with a hinged lid, it projects forward due to the rigidity of the foldable material, in particular in its upper area.
