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. A sealing element is positioned between the handle and the neck. The sealing element is translucent. An indication element is positioned between the adjacent the sealing element. A light emitting source provides electromagnetic energy to the indication element, and the electromagnetic energy passes through the sealing element.

Claims (24)

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, the oral hygiene implement further comprising:

an indication element having an outer periphery;

an output source in signal communication with the indication element; and

a reflective core disposed within the indication element, wherein the reflective core redirects light from the output source to the outer periphery of the indication element; wherein the reflective core comprises a polished area having an outer surface; wherein the outer periphery of the indication element includes a first plurality of sides; and wherein the outer surface of the polished area has a second plurality of sides, the first plurality of sides being substantially parallel to the second plurality of sides.

2. The oral hygiene implement of claim 1 , wherein the handle comprises an outer shell with an insert having a base portion disposed therein.

3. The oral hygiene implement of claim 2 , wherein the insert further comprises a forward portion, the forward portion comprising a transmission element in signal communication with the reflective core.

4. The oral hygiene implement of claim 2 , wherein the indication element is sandwiched between a first portion and a second portion of a sealing element.

5. The oral hygiene implement of claim 4 , wherein the first portion or the second portion comprise a thermoplastic elastomer.

6. The oral hygiene implement of claim 4 , wherein the first portion or the second portion are translucent.

7. The oral hygiene implement of claim 6 , wherein the first portion or the second portion comprise a first color.

8. The oral hygiene implement of claim 7 , wherein the output source comprises a light emitting device capable of emitting a second color, and wherein the first color and the second color are different.

9. The oral hygiene implement of claim 8 , wherein the light emitted goes through the first portion or the second portion.

10. The oral hygiene implement of claim 7 , wherein the output source comprises a light emitting device capable of emitting a second color, and wherein the first color and the second color are similar.

11. The oral hygiene implement of claim 10 , wherein the light emitted goes through the first portion or the second portion.

12. The oral hygiene implement of claim 4 , wherein the first portion or the second portion are transparent.

13. The oral hygiene implement of claim 1 , wherein the first plurality of sides are at an angle with the second plurality of sides.

14. 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, the oral hygiene implement further comprising:

an indication element having an outer periphery;

an output source in signal communication with the indication element; and

a reflective core disposed within the indication element, wherein the reflective core redirects light from the output source to the outer periphery of the indication element; wherein the reflective core comprises a polished area having an outer surface; and wherein the outer surface of the polished area is at a uniform distance from the outer periphery of the indication element.

15. 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, the oral hygiene implement further comprising:

an indication element having an outer periphery;

an output source in signal communication with the indication element; and

a reflective core disposed within the indication element, wherein the reflective core redirects light from the output source to the outer periphery of the indication element; wherein the reflective core comprises a polished area having an outer surface; and wherein the outer surface of the polished area is variably spaced from the outer periphery of the indication element.
