Abstract

Exemplary sanitary soap refilling systems and methods are disclosed herein. An exemplary refill refilling system includes a housing, a pump located within the housing, and a bulk storage tank connector. The bulk storage tank connector having a liquid outlet and an air inlet. A liquid inlet conduit is in fluid communication with the pump the liquid outlet. A refill connector is included. The refill connector has a liquid inlet and an air outlet. The refill connector air outlet and the bulk storage tank connector air inlet are in fluid communication with one another. The refill liquid inlet is in fluid communication with the pump.

First claim

We claim:

1. A closed loop system for refilling a plurality of soap or sanitizer containers comprising:
a mobile bulk refill container containing soap or sanitizer;
a valved connector for connecting to a mating connector of one of a plurality of soap or sanitizer containers;
a pump;
an air conduit connected between the mobile bulk refill container and the valved connector;
a first liquid conduit connected between the pump and the mobile bulk refill container; and
a second liquid conduit connected between the pump and the valved connector.

2. The closed loop system of claim 1 further comprising a stationary bulk refill container having a mating connector for connecting to the valved connecter.

3. The closed loop system of claim 1 further comprising a dispenser having a refill unit that is readily removable from the dispenser, the refill unit having a pump, a mating connector for connecting to the valved connector, and a vent for allowing air to enter the refill unit.

4. The closed loop system of claim 3 wherein the vent comprises a filter.

5. The closed loop system of claim 3 further comprising a moveable housing for concealing the valved connector.

6. The closed loop system of claim 1 wherein the pump is configured to stop pumping upon receiving a signal indicative of sensing a parameter.

7. The closed loop system of claim 6 wherein the sensed parameter is a pressure.

8. The closed loop system of claim 6 wherein the sensed parameter is a volume.

9. The closed loop system of claim 1 further comprising circuitry located proximate the mobile bulk refill container for reading information from a memory on a stationary bulk refill unit.

10. The closed loop system of claim 9 further comprising circuitry located proximate the mobile bulk refill container for writing information to memory located on the stationary bulk refill unit.

11. The closed loop system of claim 1 further comprising circuitry located proximate the mobile bulk refill container for reading information from a memory on a dispenser or dispenser refill unit.

12. The closed loop system of claim 9 further comprising circuitry located proximate the mobile bulk refill container for writing information to memory located on a dispenser or a dispenser refill unit.

13. The closed loop system of claim 1 further comprising a soap containing alcohol.

14. The closed loop system of claim 13 wherein the volume of alcohol is greater than about 5% and less than about 40% by volume of soap.

15. A closed loop system for refilling a plurality of soap or sanitizer dispensers comprising:
a bulk refill container;
a valved connector;
a pump;
an air conduit connected between the bulk refill container and the valved connector;
a first liquid conduit connected between the pump and the bulk refill container;
a second liquid conduit connected between the pump and the valved connector;
a plurality of containers;
the plurality of containers each having a mating connector for connecting to the valved connector.

16. The closed loop system of claim 15 wherein the plurality of containers in fluid communication with a plurality of fluid dispensers; wherein the fluid dispensers are configured to dispense fluid on a user's hand.

17. The closed loop system of claim of claim 16 wherein the plurality of fluid dispensers are touch-free dispensers.

18. A closed loop system for refilling a plurality of soap dispensers comprising:
a bulk refill container containing soap;
a valved connector;
a pump;
an air conduit connected between the bulk refill container and the valved connector;
a liquid conduit connected between the valved connector and the bulk refill container;
wherein the pump is located in one of the air conduits and the liquid conduit;
the plurality of soap dispensers each having a mating connector for connecting to the valved connector.

19. The closed loop system of claim 18 wherein the plurality of containers in fluid communication with a plurality of soap dispensers; wherein the fluid dispensers are configured to dispense fluid on a user's hand.

20. The closed loop system of claim of claim 19 wherein the plurality of soap dispensers are touch-free dispensers.
