Personal dispenser

1. A wearable dispenser with a replaceable one-time-use reservoir device comprising,

a wrist-band allowing the wearable dispenser to be worn by a user;

a base connected to the wrist-band; and

a replaceable one-time-use reservoir comprising

a substance to be dispensed,

a flexible bladder for holding the substance to be dispensed,

a housing with a rigid perimeter wall,

a flexible top surface attached to the rigid perimeter wall and covering the flexible bladder,

a one-way valve,

an opening, and

a plug

wherein, prior to use, the flexible bladder is totally evacuated through a removable feeder tube, filled with the substance to be dispensed, and then plugged with the plug;

wherein, once filled with any amount of the substance to be dispensed, the flexible bladder is under a constant pressure in excess of atmospheric pressure;

wherein the replaceable one-time-use reservoir is attached to the base;

wherein pressing the flexible top surface will cause the one-way valve to open, dispensing the substance to be dispensed through the opening; and

wherein the one-way valve is comprised of a spring having a spring force, a hollow stem with a dispensing channel, a plunger, and a stop.

2. The wearable dispenser with replaceable one-time-use reservoir device of claim 1 , wherein a user may empty the flexible bladder of the substance by repeatedly pressing the flexible top surface.

3. The wearable dispenser with replaceable one-time-use reservoir device of claim 2 , wherein the empty replaceable one-time-use reservoir may be detached from the base.

4. The wearable dispenser with replaceable one-time-use reservoir device of claim 3 , wherein a new replaceable one-time-use reservoir, filled with the substance, may be attached to the base.

5. The wearable dispenser with a replaceable one-time-use reservoir device of claim 4 , wherein the substance is hand sanitizer.

6. The wearable dispenser with replaceable one-time-use reservoir device of claim 5 , wherein the hand sanitizer is comprised of at least 60% alcohol and aloe vera.

7. The wearable dispenser with a replaceable one-time-use reservoir device of claim 6 , further comprising an aerator attached to the one-way valve.

8. The wearable dispenser with replaceable one-time-use reservoir device of claim 7 , wherein the hand sanitizer is further comprised of water.

9. The wearable dispenser with a replaceable one-time-use reservoir device of claim 1 , wherein the plunger is internal to the flexible bladder.

10. The wearable dispenser with a replaceable one-time-use reservoir device of claim 9 , wherein the one-way valve does not allow anything to enter the flexible bladder.

11. The wearable dispenser with a replaceable one-time-use reservoir device of claim 10 , wherein, when the flexible top surface is not being pressed, the one-way valve is in equilibrium, and the spring force of the spring is greater than the force created by pressure on the plunger, allowing the stop to prevent any substance from flowing through the dispensing channel.

12. The wearable dispenser with a replaceable one-time-use reservoir device of claim 11 , wherein pressing the flexible top surface creates sufficient pressure within the flexible bladder so that the force created by pressure on the plunger overcomes the spring force of the spring, allowing the substance to flow through the dispensing channel.

13. The wearable dispenser with a replaceable one-time-use reservoir device of claim 12 , wherein the flexible bladder is fabricated from at least one of natural rubber, nitrile rubber, butyl rubber, an elastomer, and a thermoplastic elastomer.

14. The wearable dispenser with a replaceable one-time-use reservoir device of claim 12 , wherein the flexible bladder is fabricated from at least one of polychloroprene, ethylene-propylene-diene-modified (“EPDM”), styrene-butadiene rubbers (“SBR”), polyisoprene, polyvinyl chloride (“PVC”), and acrylonitrile butadiene rubber (“ABR”).

15. The wearable dispenser with a replaceable one-time-use reservoir device of claim 14 , wherein the housing is fabricated from at least one of steel, zinc, aluminum, acrylonitrile butadience styrene (“ABS”), polycarbonate (“PC”), polypropylene (“PP”), polyamides (“nylon”), polyethylene (“PE”), and polyvinyl chloride (“PVC”).

16. The wearable dispenser with a replaceable one-time-use reservoir device of claim 15 , wherein the base is fabricated from at least one of steel, zinc, aluminum, ABS, PC, PP, nylon, PE, and PVC.
