Abstract

A method and apparatus for assuring the washing of hands by marking the hands with ink.

Claims

1. An apparatus for helping to assure the washing of a person'"'"'s hands, comprising:

(a) an ink which is removable by washing of the hands;

(b) a first ink storage chamber and a second ink storage chamber, wherein the first ink storage chamber is larger than the second ink storage chamber and wherein an ink exit point is positioned on an outer surface of the first ink storage chamber;

wherein the at least two chambers have at least two, one way valves wherein a first valve allows for the transfer of ink from the first chamber to the second chamber and a second valve allows for the transfer of ink from the second chamber to the ink exit point.

2. The apparatus of claim 1 wherein ink is any non-toxic liquid capable of marking a human hand and subsequently removable by way of hand washing with traditional alcohol or non-alcohol based cleansers or soaps.

3. The apparatus of claim 1 wherein the chambers are separated by an inner membrane.

4. The apparatus of claim 1 wherein the chambers are filled with foam capable of storing and releasing ink.

5. The apparatus of claim 1 wherein the ratio in the size difference between the two chambers is from 1:

5 to 1;

100.

6. The apparatus of claim 1 wherein .01% to 50% of the ink retained in the marking mechanism is released when activated by the application of pressure.

7. The apparatus of claim 1 wherein there is a means for temporarily affixing the apparatus to a door, a doorknob, other door opening mechanism, a toilet flushing mechanism, or urinal flushing mechanism.

8. The apparatus of claim 7 wherein the apparatus is easily removable for disposal.

9. The apparatus of claim 3 wherein at least one, one way valve is located in the inter-membrane and allows for the passage of ink from the large chamber to the small chamber;

and at least one other one-way valve which is also located in the inter-membrane and is connected to a collapsible passageway wherein the collapsible passageway traverses the large chamber and connects to an outer wall of the apparatus.

10. The apparatus as in claim 9 wherein the one-way valve connected to the collapsible passageway is a ball and cage valve that operates in the open position when no pressure is applied to the apparatus and changes to the closed position when pressure is applied to the apparatus.

11. The apparatus of claim 3 wherein at least one, one-way value is located in the outer wall of the small chamber and allows for the passage of ink from the small chamber to outside the apparatus, and another one-way valve is located in the inner membrane and allows for the passage of ink from the large chamber to the small chamber.

12. The apparatus of claim 11 wherein one of the one-way valves is a ball and chain valve.

13. A method for marking a hand comprising contacting the apparatus of claim 1with a hand wherein the apparatus is adhered to a surface;

transferring a portion of the ink between chambers, and

releasing said ink from said apparatus to said hand, wherein the ink is transferred at a point of contact between said hand and said apparatus, and wherein the amount of ink transferred to the hand is metered to be less than 0.15 ml and more than 0 ml.

14. A method of claim 13 further comprising removing said apparatus.

15. A method of claim 13 further comprising disposing of said apparatus.

17. The apparatus of claim 1 wherein ink is any non-toxic liquid capable of marking a human hand and subsequently removable only by way of hand washing with alcohol based cleansers or soaps.

16. An apparatus for helping to assure the washing of persons hands, comprising:

(a) an ink which is removable by washing of the hands;

(b) at least two separate, differently sized, ink storage chambers;

(c) at least two, one way values wherein first valve is capable of transferring ink between chambers and the second value is capable of transferring ink outside of the apparatus;

wherein a one way valve is located in an inter-membrane and allows for the passage of ink from a large chamber to a small chamber and another one-way valve which is also located in the inter-membrane and is connected to a collapsible passageway wherein the collapsible passageway traverses the large chamber and connects to an outer wall of the apparatus, and allows for the passage of ink from the small chamber to outside the

wherein the one-way valve connected to the collapsible passageway is a ball and cage valve that operates in the open position when no pressure is applied to the apparatus and changes to the closed position when pressure is applied to the apparatus.
