Abstract

An oral hygiene means, in particular a toothbrush, includes at least one application unit, at least one grip unit and at least one fastening unit that has at least one suction cup and is configured for an at least temporary fastening to surfaces. The suction cup has a non-circular cross section.

First claim

The invention claimed is:

1. A toothbrush comprising:
at least one grip unit having a longitudinal axis, a first end and a second end opposite to the first end;
at least one application unit positioned at a first end of the at least one grip unit; and
at least one fastening unit that has at least one suction cup and is configured for an at least temporary fastening to surfaces, wherein:
the suction cup has a non-circular cross section,
the fastening unit is located at a second end of the at least one grip unit and on an underside of the toothbrush,
the fastening unit has at least one disk-shaped carrier element which is configured in a deposited state, which is a state in which the toothbrush is stored on a flat and/or smooth surface with the longitudinal axis of the toothbrush at least substantially parallel to the surface, to prevent at least partially a deformation of the suction cup,
the carrier element has a thickness of at most 6 mm,
a cross section of the carrier element perpendicular to the longitudinal axis follows a cross section of the suction cup, and
in a view along the longitudinal axis, the cross section of the carrier element is at least as large as a cross section of the suction cup.

2. The toothbrush as claimed in claim 1 , wherein the suction cup is oval.

3. The toothbrush as claimed in claim 1 , wherein the suction cup has a width of at least 15 mm and/or a length of at least 10 mm.

4. The toothbrush as claimed in claim 1 , wherein the suction cup is a one-part implementation with the grip unit.

5. The toothbrush as claimed in claim 1 , wherein the carrier element in the deposited state defines at least one deposition point.

6. The toothbrush as claimed in claim 1 , wherein the carrier element is implemented partially of a soft component and partially of a hard component.

7. The toothbrush as claimed in claim 1 , wherein the fastening unit defines at least one point of maximum width.

8. The toothbrush as claimed in claim 1 , wherein the fastening unit has at least one through-passage arranged above the suction cup.

9. The toothbrush as claimed in claim 8 , wherein the through-passage is at least surrounded by a soft component.

10. The toothbrush as claimed in claim 8 , wherein the through-passage has a width of at least 4 mm and/or a height of at least 2 mm.

11. The toothbrush as claimed in claim 8 , wherein the fastening unit has at least one connection element which defines the through-passage and which is at least implemented of a hard component which is penetrated by at least one soft component.

12. The toothbrush as claimed in claim 1 , further comprising at least one base body made of a hard component, which forms at least a portion of the fastening unit, the grip unit and the application unit.

13. The toothbrush as claimed in claim 12 , wherein the base body forms at least one carrier structure arranged above the fastening unit, at least one motif element, which is encapsulated by injection-molding with a soft component through the carrier structure, being formed integrally on the carrier structure.

14. The toothbrush as claimed in claim 1 , further comprising at least one soft element made from at least one soft component which forms at least a portion of the fastening unit and the grip unit.

15. The toothbrush as claimed in claim 14 , wherein the soft element is configured to form in the deposited state all deposition points which are present.

16. The toothbrush as claimed in claim 14 , wherein the soft element extends at least on a rear face without interruption from the fastening unit via the grip unit to the application unit.

17. The toothbrush as claimed in claim 14 , wherein the soft element in at least one region between a neck element of the application unit and a grip element of the grip unit, forms at least one element which is at least partially supplied with at least one soft component from a rear face.

18. The toothbrush as claimed in claim 14 , wherein the soft element has a single injection-molding point.

19. A protective cap attached to the toothbrush as claimed in claim 1 , comprising at least one cap body, which is realized in a one-part implementation and which defines at least one interior space, which is configured for receiving at least a portion of the toothbrush, wherein the cap body has at least one hanger.

20. The protective cap as claimed in claim 19 , wherein the cap body has at least two shell elements which are connected to each other in an articulated manner, wherein each of the shell elements form a portion of the hanger.

21. A system comprising the toothbrush as claimed in claim 1 and further comprising at least one protective cap.

22. A method comprising producing the toothbrush as claimed in claim 1 .
