Abstract

A workpiece, such as a brush head, having a replacement indicator is provided, which is suitable for use with a personal care appliance. In use, the replacement indicator can provide an indication to the user recommending that the brush head be replaced after a duration has elapsed. The brush head includes a window to view the progress of the duration for recommended replacement and an indication when the duration has elapsed. In some embodiments, the duration is commenced when the brush head is initially installed on the personal care appliance.

Claims

1. A skin brush head for use with a motorized personal appliance, comprising:

a body having an inner surface, an outer surface, and a window portion through which light transmits between the inner surface and the outer surface;

a treatment applicator coupled to the outer surface of the body, wherein the treatment applicator is configured to apply treatment to a skin portion; and

a replacement indicator associated with the skin brush head, the replacement indicator configured to provide an indication through the window portion for recommending replacement of the skin brush head to a user after a duration of time the skin brush head is in use, wherein the duration of time commences upon initial attachment of the skin brush head to the motorized personal appliance;

wherein the replacement indicator is configured to indicate when the duration of time has elapsed by spreading a dye.

2. The skin brush head of claim 1, wherein the window portion is positioned within a void in the treatment applicator such that the window portion is visible by the user when viewed from the outer surface.

3. The skin brush head of claim 1, further comprising an activating member extending from the inner surface and configured to initiate spreading of the dye upon initial attachment of the skin brush head to the motorized personal appliance.

4. The skin brush head of claim 1, wherein the dye spreads to a demarcation visible through the window portion when the duration of time has elapsed.

5. The skin brush head of claim 4, wherein the duration of time to reach the demarcation is between about thirty days and one hundred eighty days.

6. The skin brush head of claim 4, wherein the duration of time to reach the demarcation is between sixty days and one hundred twenty days.

7. The skin brush head of claim 4, wherein the duration of time to reach the demarcation is between eighty-five days and ninety-five days.

8. The skin brush head of claim 1, wherein the replacement indicator is disposed on the inner surface of the body.

9. The skin brush head of claim 1, wherein the treatment applicator includes a plurality of bristles.

10. The skin brush head of claim 1, wherein the body is manufactured from a material of one or more of High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), rubber, Polypropylene (PP), nylon, Acrylonitrile Butadiene Styrene (ABS), Polybutylene Terephthalate (PBT), HYTREL®

, polyurethane, co-polyester, and other thermo plastic or polymer.

11. A skin brush head, comprising:

a body having a window portion;

a plurality of bristles coupled to an outer surface of the body forming a central void adjacent the window portion, wherein the plurality of bristles are configured to apply treatment to a skin portion;

a replacement indicator associated with the skin brush head, the replacement indicator configured to provide an indication through the window portion for recommending replacement of the skin brush head to a user after a duration of time the skin brush head is in use; and

an activating member extending from an inner surface of the body, the activating member configured to initiate the duration of time upon initial attachment of the skin brush head to a personal appliance;

wherein the replacement indicator is configured to indicate when the duration of time has elapsed by spreading a dye.

12. The skin brush head of claim 11, wherein the activating member is configured to initiate spreading of the dye upon initial attachment of the skin brush head.

13. The skin brush head of claim 11, wherein the dye spreads to a demarcation visible through the window portion when the duration of time has elapsed.

14. The skin brush head of claim 13, wherein the duration of time to reach the demarcation is between about thirty days and one hundred eighty days.

15. The skin brush head of claim 13, wherein the duration of time to reach the demarcation is between sixty days and one hundred twenty days.

16. The skin brush head of claim 13, wherein the duration of time to reach the demarcation is between eighty-five days and ninety-five days.

17. The skin brush head of claim 11, wherein the window portion includes a lens configured to magnify at least a portion of the replacement indicator.

18. The skin brush head of claim 11, wherein the body is manufactured from a material of one or more of High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), rubber, Polypropylene (PP), nylon, Acrylonitrile Butadiene Styrene (ABS), Polybutylene Terephthalate (PBT), HYTREL®

, polyurethane, co-polyester, and other thermo plastic or polymer.
