  • Patent number: 8944342
    Abstract: A Two-part, Wall-mountable Electrochemical Dispenser. The dispenser assembly consists of a disposable fluid storage reservoir and a non-disposable dispenser. The dispenser holds an electrochemical gas generator, its associated electronics, and a power source. The generator can be set for fluid delivery rates of between 1 mL/day and 50 mL/day. The system has a battery-determined operational life of about 2 years, assuming rates of up to 2 mL/day and 2 C-size batteries. The fluid storage reservoir is formed by two plastic shells separated by a plastic diaphragm. Gas produced by the generator acts on the diaphragm thereby displacing fluid that is then captured by an evaporation pad from which it can readily emanate into the environment. The reservoir can be removed and discarded after depletion of the liquid, and then replaced by another filled assembly. As needed, the refill holds an anti-theft coded card that prohibits the re-use of the refill.

    Abstract: An electrostatic spraying device has a capability of confirming that the device is ready for making an electrostatic spraying of the liquid composition on a user's skin. The device includes a nozzle and a pump for dispensing the liquid composition out through the nozzle. An emitter electrode is disposed to electrostatically charge the liquid composition being dispensed for making the electrostatic spraying. The device is provided with a power switch and a selector for selection between a spraying mode and a dripping mode. In the dripping mode, the pump is alone actuated to dispense the liquid composition absent electrostatic charge. In the spraying mode, both of the pump and the emitter electrode are activated to make the electrostatic spraying. Thus, the user can be easy to drip the liquid composition by simply manipulating the selector prior to initiating the electrostatic spraying.
