Abstract

A touchless dispenser is provided for a pressurized container including a valve member. The dispenser comprises a housing mountable to the container. An electrically controlled valve in the housing includes an inlet and an outlet. The inlet maintains the valve member in an open position incident to the housing being mounted on the container. A nozzle extends between the valve outlet and a discharge orifice. A sensor senses a user'"'"'s hand proximate the discharge orifice. A control in the housing is operatively coupled to the sensor and the electrically controlled valve. The control controls operation of the electrically controlled valve to dispense a select dosage of product from the container responsive to the sensor sensing presence of a user'"'"'s hand proximate the discharge orifice.

Claims

1. A touchless dispenser for a pressurized container including a valve member, comprising:

a housing mountable to the container, the housing comprising a base and a cover, the base defining an interior space and the cover being removably receivable on the base to enclose the interior space, the base having a neck mountable to the container and first and second support structure in the interior space;

an electrically controlled valve mountable to the first support structure and having a pair of electrical leads extending therefrom, the electrically controlled valve including an inlet and an outlet, the inlet actuating the valve member to an open position incident to the base being mounted on the container;

a nozzle extending between the valve outlet and a discharge orifice;

a circuit board mountable to the second support structure and comprising battery mounting clips mounted to the circuit board, a sensor mounted to the circuit board for sensing proximity of a user'"'"'s hand, terminal pads for electrically engaging the valve electrical leads, and a control circuit operatively coupled to the sensor, the battery clips and the terminal pads, the control circuit controlling operation of the electrically controlled valve to dispense a dosage of product from the container using battery power responsive to the sensor sensing presence of a user'"'"'s hand proximate the discharge orifice.

2. The touchless dispenser of claim 1 wherein the base comprises a first sensor opening proximate the discharge orifice, and the sensor comprises an infrared sensor positioned at the first sensor opening.

3. The touchless dispenser of claim 1 wherein the terminal pads engage the valve electrical leads incident to the circuit board and electrically controlled valve being mounted in the base.

4. The touchless dispenser of claim 3 wherein the valve electrical leads extend upwardly incident to the electrically controlled valve being mounted to the first support structure and the terminal pads are located on a bottom surface of the circuit board.

5. The touchless dispenser of claim 3 wherein the terminal pads comprise contact receptacles, and the electrical leads plug into the contact receptacles.

6. The touchless dispenser of claim 3 wherein the base comprises a second sensor opening proximate the discharge orifice, and the sensor further comprises an LED positioned at the second sensor opening.

7. The touchless dispenser of claim 6 wherein the control circuit periodically activates the LED.
