Abstract

An oral hygiene implement is described herein. The oral hygiene implement has a handle; a head, and a neck disposed between the handle and the head. The head has a plurality of contact elements. An indication element is positioned between the neck and handle of the oral hygiene element. A transmission element is positioned between the indication element and a light emitting source. The light emitting source provides electromagnetic energy to the transmission element.

First claim

What is claimed is:

1. An oral hygiene implement comprising a handle, a head, and a neck disposed between the handle and the head, the head comprising a plurality of contact elements extending from a first surface, the oral hygiene implement further comprising:
an output source wherein the output source is a light;
a transmission element in electromagnetic energy communication with the output source wherein the transmission element and the output source are discrete;
a transmission element ring comprising a bottom edge and in electromagnetic energy communication with the transmission element;
a reflective core disposed within the transmission element, wherein the reflective core redirects electromagnetic energy from the output source to an indication element;
wherein the indication element disposed between the handle and the neck comprises an outer lateral surface extending around a circumference wherein light is emitted from the lateral surface of the indication element and wherein the light is distributed approximately evenly around the circumference.

2. The oral hygiene implement of claim 1 wherein the reflective core comprises one or more faces.

3. The oral hygiene implement of claim 2 wherein the faces are polished.

4. The oral hygiene implement of claim 2 wherein the reflective core is wedge shaped.

5. The oral hygiene implement of claim 1 wherein the reflective core comprises an empty recess.

6. The oral hygiene implement of claim 1 wherein the transmission element is non-linear.

7. The oral hygiene implement of claim 1 wherein the bottom edge of the transmission element ring comprises a reflective surface.

8. The oral hygiene implement of claim 1 wherein the bottom edge of the transmission element ring comprises a plurality of surface contours.

9. The oral hygiene implement of claim 8 wherein the transmission element ring comprises at least three surface contours and the distance between the surface contours varies.

10. The oral hygiene implement of claim 8 wherein there are fewer surface contours near the reflective core as compared to the number of surface contours away from the reflective core.

11. The oral hygiene implement of claim 8 wherein one or more surface contours are positioned on an inner surface of the transmission element ring.

12. The oral hygiene implement of claim 1 , wherein the transmission element comprises at least one curve or angle.

13. The oral hygiene implement of claim 1 , wherein the transmission element ring comprises one or more surface contours.

14. The oral hygiene implement of claim 1 wherein the indication element signals to a user one or more conditions selected from the group consisting of when a user has brushed for an adequate amount of time, when the toothbrush needs to be replaced, when the user is brushing too hard, and combinations thereof.

15. The oral hygiene implement of claim 14 wherein the indication element signals to a user two or more conditions.

16. The oral hygiene implement of claim 1 wherein the head further comprises a second surface, opposite the first surface and wherein a tongue cleaner extends from the second surface.

17. The oral hygiene implement of claim 1 wherein the light is an LED.
