Abstract

The invention is directed to a toothbrush having a brush section 20 comprising a bristle carrier 22 and bristles 24 fixedly secured thereto, with the brush section 20 being provided with components made of silver. Separate structures 28 are provided for fixedly securing the bristles 24 in their proper location in the bristle carrier 22, which separate structures 28 are made of a material with oligodynamic action.

Claims

1. A toothbrush comprising:

a brush section including a bristle carrier and bristles fixedly secured to the bristle carrier, and a separate member fixedly securing the bristles to the bristle carrier, said separate member being made of material with oligodynamic action.

2. A toothbrush as claimed in claim 1, wherein said bristle carrier further includes a bore, said separate member fixedly securing the bristles within the bore in the bristle carrier, said separate member configured as a small anchoring plate arranged approximately centrally between the individual bristles which together form a bristle tuft anchored in the bristle carrier.

3. A toothbrush as claimed in claim 1 or claim 2, wherein said separate member is made of a material comprising silver.

4. A toothbrush as claimed in claim 3, wherein said separate member is comprised of an alloy of silver and copper with a silver content of between 90% and 97%, approximately, and a copper content of between 10% and 3%.

5. A toothbrush as claimed in claim 3 wherein said separate member comprises a silver alloy with a silver content of at least approximately 70%.

6. A toothbrush as claimed in claim 3 wherein said separate member is comprised of an alloy of silver and titanium with a silver content of approximately 70% and a titanium content of approximately 30%.

7. A toothbrush as claimed in claim 1 or claim 2, wherein said separate member is plated with a coating of essentially pure silver.

8. A toothbrush as claimed in claim 7, wherein the silver coating has a thickness of between 5 and 50 micrometers.

9. A toothbrush as claimed in claim 8 wherein the silver coating has a thickness of between 5 and 20 micrometers.

10. A toothbrush as claimed in claim 1 or claim 2, wherein said separate member is made of silver with a percentage purity of over 99%.

11. A toothbrush as claimed in claim 1 or claim 2, wherein said separate member has a tensile strength greater than approximately of 500 N/mm².

12. A toothbrush as claimed in claim 2, wherein said separate member is comprised of stainless steel.

13. A toothbrush as claimed in claim 1 wherein said material with oligodynamic action is selected from a group consisting of cadmium, silver, brass, copper, stainless steel, titanium and mercury.

14. A toothbrush as claimed in claim 13 wherein said material with oligodynamic action is silver.

15. A toothbrush as claimed in claim 13 wherein said material with oligodynamic action is copper.

16. A toothbrush as claimed in claim 13 wherein said material with oligodynamic action is stainless steel.

17. A toothbrush as claimed in claim 1 further comprising a plurality of separate members, said bristle carrier further comprising bores, each of said separate members fixedly securing bristle tufts, each formed of a plurality of said bristles, within a corresponding bore.
