Abstract

A door mountable device for facilitating detection of hygienic hand washing. A dye dispenser is mounted on a door handle in a manner such that a soap washable dye is deposited on hands that contact the handle upon entry into a restroom facility. The resulting dye stain area is removed by thorough hand washing. Any stain remaining upon exiting the restroom is an indicator that hands have not been hygienically washed.

Claims

1. A device for depositing onto a hand surface a soap washable dye liquid as an indicator for detecting when the hand surface has been hygienically washed, said device being detachably mountable on a door handle and comprising:

a. a chassis which is attachable to said door handle, wherein said chassis comprises;

i. a pair of oppositely disposed side walls having inwardly projecting flange members positioned at each end of each side wall; and

ii. a partition which is positioned between the side walls and is attached to each side wall at a location inward of said flange members, so as to form a first chamber on one side of said partition and a second chamber on the other side of said partition, both chambers being within said chassis; and

b. a dye applicator assembly which is removably attached to said chassis.

2. The device of claim 1 wherein said applicator assembly is removably attached to said first chamber.

3. The device of claim 2 wherein part of said door handle is positioned within said second chamber.

4. The device of claim 2 wherein the applicator assembly comprises an applicator, a perforated cover for said applicator and a reservoir for a soap washable dye liquid.

5. The device of claim 4 wherein the applicator is a liquid absorbing material.

6. The device of claim 4 wherein the applicator is a sponge.

7. The device dispenser of claim 4 wherein the reservoir comprises a trough having a base, two oppositely disposed side walls attached to the base, and two oppositely disposed end walls attached to the base and to the side walls.

8. The device of claim 7 wherein the perforated cover is attached to the side walls and end walls of the reservoir.

9. A device for depositing onto a hand surface a soap washable dye liquid as an indicator for determining whether the hand surface has been hygienically washed, said device being detachably mountable on a door surface or on a push plate attached to a door surface and comprising:

a. a chassis which is attachable to said door surface or push plate; and

b. an applicator assembly which is removably attached to said chassis wherein said applicator assembly comprises an applicator, a reservoir for the soap washable dye and a perforated cover for said reservoir, and wherein said reservoir comprises a trough having a base, two oppositely disposed side walls attached to the base, and two oppositely disposed end walls attached to the base and to the side walls.

10. The device of claim 9 wherein the chassis comprises:

a. a pair of oppositely disposed side walls having inwardly projecting flange members positioned at each end of each side wall; and

b. a base which is positioned between the side walls and which is attached to each side wall.

11. The device of claim 9 wherein the chassis is attachable to said door surface or push plate with an adhesive material.

12. The device of claim 9 wherein the applicator is a liquid absorbing material.

13. The device of claim 9 wherein the perforated cover is attached to the side walls and end walls of the reservoir.
