Abstract
A hand cleaner fluid dispenser, including a reservoir for containing hand cleaner fluid to be dispensed; a dispenser outlet for discharge of the hand cleaner fluid from the reservoir; and a discharge mechanism operable to discharge a drop of the hand cleaner fluid from the dispenser outlet when activated. A levitator device is incorporated into the hand cleaner fluid dispenser, and is operable to levitate the drop of hand cleaner fluid at a position where the drop is accessible to be taken by a user's hand.
Claims20
A method of dispensing a fluid onto a user's hand characterized by:
- levitating in air a first drop of the fluid where the drop is accessible to be taken by the user's hand;
- and
- moving the user's hand to take the drop.
A method of dispensing a fluid characterized by:
- sensing when a user is proximate to a levitator device, and
- on sensing a user to be proximate to the levitator device, aerodynamically levitating in air a first drop of the fluid with an upwardly directed flow of air for a period of time at a height above the levitator device within a range of positions where the drop is accessible to be taken by a user's hand,
- wherein the range of positions where the drop is accessible to be taken by the user's hand permits the drop to be grasped by the user's hand without the user's hand engaging anything other than the drop and the air within which the drop is levitated.
