Abstract

A hand washing device and method encouraging hand washing includes a display panel, a message “WASH UP with Soap and Water. Get rid of germs in only 15 seconds.” and may have one of a variety of timing means to time the wash cycle or the user may use an ordinary clock. Germ illustrations indicate consequences. The panel is on personal and public use soap dispensers and return springs are used as the timing device.

Claims

1. A method to time handwashing, comprising the steps of:

a) providing a container;

b) establishing a hand wash soap in said container;

c) generating travel in a reciprocal means of a soap dispenser element from a first position to a second position;

d) dispensing said hand wash soap from said container;

e) activating a return element coupled to said reciprocal means to return said reciprocal means from said second position to said first position in a time interval; and

f) providing a time interval control element coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval.

2. The method to time handwashing as described in claim 1, wherein said step generating travel in a reciprocal means of a soap dispenser element from a first position to a second position comprises generating travel in a plunger from a first position to a second position.

3. The method to time handwashing as described in claim 2, wherein said step of providing a time interval control element coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval comprises the step of providing a drag means coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval.

4. The method to time handwashing as described in claim 3, wherein said step of providing a drag means coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval comprises the step of adjusting engagement of a set screw with said plunger.

5. The method to time handwashing as described in claim 3, wherein said step of providing a drag means coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval comprises the step of adjusting engagement of a squeeze clamp with said plunger.

6. The method to time handwashing as described in claim 3, wherein said step of providing a drag means coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval comprises the step of coupling a series of axially spaced circumferential protrusions coupled to said plunger which slidely engage a surface of said container.

7. The method to time handwashing as described in claim 2, wherein said step of providing a time interval control element coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval comprises the step of providing an amount of weight coupled to said reciprocal means which allows adjustment of said time interval to a selected hand wash time interval.

8. The method to time handwashing as described in claim 2, wherein said step of activating a return element coupled to said reciprocal means to return said reciprocal means from said second position to said first position in a time interval comprises the step of generating an amount of tension in a spring adjusted to return said reciprocal means from said second position to said first position in said selected hand wash time interval.

9. The method to time handwashing as described in claim 2, further comprising the step of coupling an indicia to said plunger which becomes visible when said plunger returns to said first position.

10. The method to time handwashing as described in claim 2, further comprising the step of selecting said indicia coupled to said plunger from the group consisting of a happy face, a mark, and a symbol.

11. The method to time handwashing as described in claim 1, wherein said step of generating travel in a reciprocal means of a soap dispenser element from a first position to a second position comprises the step of generating travel in a dispenser lever from a first position to a second position.

12. The method to time handwashing as described in any one of claims 1, 3, 4, 5, 6, 7, 9, or 11, further comprising the step of adjusting said selected hand wash time interval to provide a duration of time between about 10 seconds and about 20 seconds.
