Abstract
A fluid dispenser includes a disposable reservoir for containing a fluid and a tube depending therefrom for dispensing measured quantities of fluid. The tube includes a fluid dispensing orifice and a plunger for forcing measured quantities of fluid through the orifice. A solenoid disposed adjacent tube magnetically engages and moves the plunger in order to cause the plunger to force the measured quantities of fluid through the orifice. A control system is provided which includes a Theremin antenna for sensing the presence of a user's hand beneath the orifice and providing electrical current to the solenoid to enable the solenoid to magnetically engage and move the plunger.
