Touch-free pressurized can dispenser
First Claim
1. A dispenser for automatically dispensing an amount of product from a pressurized can having a nozzle which dispenses product when the nozzle is tilted from its normal vertical straight up position relative to the can, comprising:
- a dispenser housing for holding a pressurized dispenser can in an upside-down position;
a sensor which senses the presence of a user'"'"'s hands beneath the dispenser housing;
an actuator assembly which tilts the nozzle on the can in response to detecting the user'"'"'s hands, wherein the actuator assembly comprises a motor and an actuator lever, and wherein the actuator assembly includes an eccentrically arranged actuator knob which rotates eccentrically when the motor is energized, and wherein the actuator lever has an elongated circular profile opening which receives the eccentrically arranged actuator knob, and moves the actuator lever to tilt the can nozzle, wherein the actuator lever is mounted at a pivot point at one end to the dispenser housing and wherein the actuator lever has an actuator surface at the other end of the actuator lever which contacts the can nozzle when the actuator lever pivots between a first pivot dispensing position to thereby actuate the can nozzle, and a second pivot non-dispensing position wherein the actuator surface does not actuate the can nozzle, whereby an amount of product from the can is dispensed in a touch-free manner.

Abstract
An automatic touch-free dispenser provides dose dispensing of a product from a pressurized can by sensing or detecting the presence of a user'"'"'s hands, and an actuator assembly which tilts the nozzle on the can in response to such detection, to thereby dispense product from the can. The can may hold a healthcare product, such as a sanitizer, food product, or any other fluid product pressurized in a can. The actuator assembly includes a DC motor which drives a cam, which in turn pushes an actuator lever into the nozzle for a certain dispensing time. The number of doses, detection range, and motor speed, can be adjusted.

11. A method of dispensing an amount of product from a pressurized can having a dispensing nozzle, comprising:
-
providing a dispenser housing which holds a can of pressurized product in an upside-down position with the dispensing nozzle faced downward; sensing the presence of a user'"'"'s hands near the nozzle; activating an actuating mechanism which rotates an eccentrically arranged actuator knob within an elongated circular profile opening in an actuator lever which tilts the nozzle on the can in response to sensing a user'"'"'s hands, wherein the actuator lever is mounted at a pivot point at one end to the dispenser housing and wherein the actuator lever has an actuator surface at the other end of the actuator lever which contacts the can nozzle when the actuator lever pivots between a first pivot dispensing position to thereby actuate the can nozzle, and a second pivot non-dispensing position wherein the actuator surface does not actuate the can nozzle, to thereby dispense product from the can. - View Dependent Claims (12, 13)
