Bulk refill protection sensor for dispensing system

1. A bulk refill system comprising:

a refill container for holding a liquid to be dispensed;

wherein the refill container is opaque;

wherein the refill container is sealed from the outside environment;

a sensor for sensing an increase in light in the container;

a refill controller configured to receive one or more signals from the sensor indicative of an increase in light; and

wherein the refill controller transmits a signal to allow an electronically controllable valve to open if the refill controller has not received one or more signals indicative of an increase in light.

2. The bulk refill system of claim 1 , wherein the electronically controllable valve is located on the refill container.

3. The bulk refill system of claim 2 , further comprising a soap or sanitizer dispenser and wherein the electronically controllable valve is located on a soap or sanitizer dispenser and the refill controller transmits the signal to a dispenser controller which controls the electronically controllable valve.

4. The bulk refill system of claim 2 , further comprising a second electronically controllable valve wherein the second electronically controllable valve is on one of the refill container and a soap or sanitizer dispenser.

5. The bulk refill system of claim 2 wherein the sensor is located proximate a translucent window on the refill container.

6. The bulk refill system of claim 2 wherein the sensor is located at least partially within the refill container.

7. The bulk refill system of claim 2 further comprising a light pipe for directing light from inside the refill container to the light sensor.

8. The bulk refill system of claim 2 further comprising an indicator for indicating that the refill container has been breached.

9. The bulk refill system of claim 8 wherein the indicator is a light emitting diode.

10. The bulk refill system of claim 2 further comprising circuitry for transmitting a signal to a remote computer that the refill container has been breached.

11. The bulk refill system of claim 10 wherein the circuitry for transmitting a signal is wireless communication circuitry.

12. A bulk refill system comprising:

a refill container for holding a liquid to be dispensed;

wherein the refill container is sealed from the outside environment;

a sensor for sensing the container has been breached, wherein the sensor senses one of an increase in light being let into the container, vibration, noise, or shock;

a refill controller configured to receive one or more signals from the sensor indicative of a breach of the container;

refill communication circuitry; and

an outlet port on the refill container;

one or more soap or sanitizer dispensers configured to be refilled by the refill container;

the one or more soap or sanitizer dispensers having

an inlet port configured to mate with the outlet port on the refill container;

a dispenser controller;

dispenser communication circuitry for communicating with the refill communication circuitry; and

an electronically controllable valve;

wherein the refill controller transmits a signal to the dispenser controller indicative of whether the refill container has been breached; and

wherein the dispenser controller allows the electronically controllable valve to open if the refill controller has not received one or more signals indicative of a breach.

13. The bulk refill system of claim 12 , further comprising a second electronically controllable valve wherein the second electronically controllable valve is on the refill container.

14. The bulk refill system of claim 12 wherein the refill container is opaque and the sensor senses an increase in light within the refill container.

15. The bulk refill system of claim 12 wherein the sensor is located at least partially within the refill container.

16. The bulk refill system of claim 12 wherein the refill communication circuitry and the dispenser communication circuitry are wireless communications circuitry.

17. A method for controlling fluid flow to a dispensing system comprising:

providing a refill container having

a sensor for sensing a breach of the refill container;

a refill controller for receiving one or more signals from the sensor;

refill container communications circuitry for communicating one or more signals; and

an outlet nozzle;

providing a soap or sanitizer dispenser having

an inlet port for connecting to the outlet nozzle;

a dispenser container;

a conduit between the inlet port and the dispenser container;

an electronically controllable valve in the conduit between the inlet port and the dispenser container;

a dispenser controller;

dispenser communications circuitry for receiving the one or more signals;

connecting the outlet nozzle to the inlet port;

receiving a signal from the refill communications circuitry by the dispenser communications circuitry;

causing the electronically controlled valve to open if the signal is indicative of the refill container not having been breached and not causing the electronically controlled valve to open if the signal is indicative of the refill container having been breached.

18. The method of claim 17 wherein the refill communications circuitry and the dispenser communications circuitry comprises wireless communication circuitry.

19. The method of claim 17 further comprising transmitting a notification signal of a breach to a central computer to notify of a breach of the integrity of the refill container.

20. The method of claim 17 further comprising a refill container valve and wherein the refill container valve is controllable by the refill controller and wherein the refill container valve is opened if no breach of the integrity of the refill container is detected and is not opened if a breach of the integrity of the refill container is detected.
