Abstract

A device for wearing on a person's wrist and dispensing a liquid, such as sanitizing liquid, includes a wristband that has a central mount and two opposing ends. Each end has one part of a two-part mechanical fastener. A container is fixed with the central mount of the wristband and has a top side, a side wall, and a bottom side. The side wall includes an open portion that is fixed with a nozzle. The top side includes a resilient pump diaphragm. The top side, side wall, and bottom side all define an internal volume within the container. Preferably the bottom side of the container includes a removable cap that is removable form the container to provide access to the internal space for refilling the container with the liquid. Depressing the pump diaphragm forces the liquid to be dispensed out of the nozzle.

Claims (26)

1. A device for wearing on a wrist of a person and dispensing a liquid, the device comprising:

a wristband having a central mount and two opposing ends, each end having one part of a two-part mechanical fastener cooperative to secure the wristband around the person's wrist;

a container fixed with the central mount of the wristband, the container having a top side with a resilient pump diaphragm, a side wall having an open portion fixed with a nozzle, and a bottom side at least partially openable to allow filling of the container with the liquid, the top side, the side wall, and the bottom side all defining an internal volume within the container;

whereby with the wristband secured around the wrist of the person, the person can depress the resilient pump diaphragm to force the liquid out of the nozzle to dispense the liquid;

wherein the nozzle is normally closed when the resilient pump diaphragm is not depressed, but, under pressure when the resilient pump diaphragm is depressed, the nozzle opens to allow dispensing of the liquid therethrough; and

wherein the nozzle includes an umbrella valve integrally formed therewith, and wherein the open portion of the side wall of the container includes a central aperture through which the nozzle traverses and a plurality of air apertures spaced radially around the central aperture through which air is pulled into the internal volume of the container when the resilient pump diaphragm is released.

2. The device of claim 1 wherein the bottom side of the container includes a removable cap that is removable from the container to provide access to the internal volume for refilling the container with the liquid.

3. The device of claim 2 wherein the removable cap includes screw threads that engage cooperative screw threads of the side wall of the container.

4. The device of claim 1 wherein the resilient pump diaphragm is made with an elastomeric rubber material, whereby depressing the resilient pump diaphragm reduces the internal volume within the container to force the liquid through the nozzle.

5. The device of claim 2 wherein the container is removably attached with the central mount of the wristband, such that with the removable cap removed from the container, the container is free to slide out of the central mount of the wristband.

6. The device of claim 1 wherein the central mount of the wristband includes an opening cooperative with the nozzle of the container to allow the liquid to be dispensed through the opening of the wristband.

7. The device of claim 6 wherein the container and the central mount of the wristband are keyed so that the container only fits into the central mount of the wristband in one orientation wherein the nozzle is aligned with the opening in the wristband.

8. The device of claim 1 wherein the nozzle is oriented away from the user on his left wrist, such that with his right hand the user can depress the resilient pump diaphragm while cupping his right hand under the nozzle to receive the liquid in his right hand.

9. The device of claim 1 wherein the nozzle is oriented away from the user on his right wrist, such that with his left hand the user can depress the resilient pump diaphragm while cupping his left hand under the nozzle to receive the liquid in his left hand.

10. The device of claim 2 further including an auxiliary container mount, wherein the container can be removed from the wristband and inserted into the auxiliary container mount.

11. The device of claim 1 wherein at least a portion of the container is transparent, whereby the amount of liquid in the internal volume can be visually ascertained.

12. The device of claim 2 wherein the side wall of the container includes a rim and the removable cap includes a cooperative receiver that forms an annular seal with the rim, the receiver temporarily deforming when the rim is inserted therein to form a water-tight frictional-fit seal.

13. The device of claim 12 wherein the removable cap is tethered to the rim at a living hinge integrally formed with the cap and the container.

14. The device of claim 1 wherein the resilient pump diaphragm is made with a low density polyethylene.

15. A device for wearing on a wrist of a person and dispensing a liquid, the device comprising:

a wristband having a central mount and two opposing ends, each end having one part of a two-part mechanical fastener cooperative to secure the wristband around the person's wrist;

a container fixed with the central mount of the wristband, the container having a top side with a resilient pump diaphragm, a side wall having an open portion fixed with a nozzle, and a bottom side at least partially openable to allow filling of the container with the liquid, the top side, side wall, and bottom side all defining an internal volume within the container;

whereby with the wristband secured around the wrist of the person, the person can depress the resilient pump diaphragm to force the liquid out of the nozzle to dispense the liquid;

wherein the bottom side of the container includes a removable cap that is removable from the container to provide access to the internal volume for refilling the container with the liquid;

wherein the side wall of the container includes a rim and the removable cap includes a cooperative receiver that forms an annular seal with the rim, the receiver temporarily deforming when the rim is inserted therein to form a water-tight frictional-fit seal.

16. The device of claim 15 , wherein the removable cap is tethered to the rim at a living hinge integrally formed with the cap and the container.
