Abstract

A refill container is disclosed which utilizes an enclosure with at least one orientational tab and a neck that carries a pump mechanism with a nozzle. The refill container provides a collar with a notch that receives the orientational tab and axially receives the neck. The refill container is axially received by a release mechanism of a dispenser housing.

Claims

1. A dispensing system, comprising:

a housing;

an emitting device integrally carried by said housing;

a receiving device carried by said housing, said emitting device and said receiving device maintained in a spaced apart relationship;

a refill container carrying a material and an electronic key, said refill container receivable in said housing such that said electronic key is received between said emitting and receiving devices in said spaced apart relationship;

an operational mechanism associated with one of said housing and said refill container; and

a controller in communication with said emitting and receiving devices, said controller having a matching key;

said emitting device generating a first signal that passes to said electronic key, said electronic key emitting a second signal in response thereto, said second signal being received by said receiving device for comparison to said matching key to selectively enable said operational mechanism to dispense material from said refill container.

2. The system according to claim 1, wherein said refill container comprises:

an enclosure for carrying said material;

a pump mechanism coupled to said enclosure; and

a nozzle operatively connected to said pump mechanism, wherein actuation of said pump mechanism dispenses a quantity of material through said nozzle.

3. The system according to claim 2, wherein said housing comprises:

a pump actuator for receiving at least said nozzle, said pump actuator carrying said emitting device and said receiving device in said spaced apart relationship.

4. The system according to claim 3, wherein said emitting and receiving devices are emit and receive coils, respectively, which have a gap surface therebetween that forms a coil gap, wherein said emit coil and said receive coil are connected to said controller, and

wherein said electronic key comprises a key coil received in said coil gap, said key coil having a key capacitor connected thereto, wherein said key capacitor has a key capacitance value.

5. The system according to claim 4, wherein said matching key has a matching capacitor, and wherein a value of said matching capacitor must be substantially equivalent to said key capacitance value said refill container to enable said operational mechanism.

6. The system according to claim 4, wherein said pump actuator is annular with a nozzle opening therethrough and wherein said emitting and receiving coils are axially aligned with said key coil when said refill container is received in said pump actuator.

7. The system according to claim 3, wherein said matching key is a digital key that generates a reference value which must be substantially equivalent to said electronic key.

8. The system according to claim 7, wherein said electronic key comprises a key coil having a key capacitor connected thereto.

9. The system according to claim 8, further comprising:

an infrared sensor proximally positioned about said dispensing interface, said controller connected to said infrared sensor, said controller initiating a dispensing cycle of said dispensing interface when said infrared sensor detects the presence of a target.

10. The system according to claim 8, wherein said controller adjusts an amount of energy emitted by said sensor depending detection of said target for a predetermined period of time.

11. The system according to claim 2, wherein said electronic key has one of a selected number of electronic signatures.

12. The system according to claim 11, wherein said selected number of signatures corresponds to different variations of dispensing systems in which the refill container can be received.
