Abstract

A programmable dispenser, especially for dispensing an olfactory stimulating material from a source of the material, is presented. More particularly, the present invention relates to a dispenser for an olfactory stimulating material, such as an air freshener composition, wherein the dispenser can be programmed so as to be operational within a wide variety of operating modes, such as starting and ending operations at specific times during the day, being operational during specific days of the week, and dispensing frequency (i.e., in the case of an aerosol or pump source) and/or intensity (i.e., in the case of a gel or cartridge source).

Claims

1. A programmable dispenser for a material, comprising:

a source of material to be dispensed;

a housing having an internal cavity sized to permit insertion thereinto of the source of material to be dispensed;

an assembly for dispensing the material to be dispensed;

a programmable controller in operational contact with the assembly, the programmable controller determining the time of operation and frequency and/or intensity of operation of the assembly, wherein the controller is capable of being programmed so as to set, for the dispenser, operational parameters selected from the group consisting of;

days of the week during which the material will be dispensed, the time during the day at which the dispenser will begin dispensing for the day, the time during the day at which the dispenser will stop dispensing for the day, and the frequency and/or intensity of dispensing;

wherein the dispenser provides a daily “

day count”

indicative of the number of days remaining for which there is material to be dispensed, the first day “

day count”

being computed from;

(a) an initial determination of a total score representative of the total amount of material available to be dispensed;

(b) dividing the total score by the dispensing time per day for a selected set of operational parameters; and

(c) rounding the resulting quotient down to the next whole number;

and wherein the “

day count”

for a successive day is computed from;

(a) subtracting, from the total score, the dispensing time per day from the previous day, so as to compute a new “

total score;

”

(b) dividing the new total score by the dispensing time for a successive day for a selected set of operational parameters; and

(c) rounding the resulting quotient down to the next whole number.

2. The dispenser of claim 1, wherein the material to be dispensed comprises an olfactory stimulating material, an insecticide, a pesticide or a bactericide.

3. The dispenser of claim 1, wherein the source of material to be dispensed comprises a spray head dispenser.

4. The dispenser of claim 3, wherein the spray head dispenser comprises a depressible spray head and the assembly comprises an actuator for depressing the spray head in response to the controller.

5. The dispenser of claim 3, wherein the spray head dispenser comprises an aerosol can and the assembly comprises a solenoid/valve assembly wherein the solenoid is in operational connection with both the valve and the aerosol dispenser to dispense the material to be dispensed in response to the controller.

6. The dispenser of claim 1, wherein the controller further comprises at least one preprogrammed mode of operation of the dispenser.

7. The dispenser as claimed in claim 1, wherein the dispenser further comprises a remote control capable of remotely communicating programming instructions to the controller, the remote control itself comprising a display for displaying the “

day count”

.

8. The dispenser as claimed in claim 1, wherein the dispenser further comprises a display for displaying the “

day count”

.

9. The dispenser as claimed in claim 1, wherein the total score is determined by the number of hours it takes to dispense a predetermined amount of the material to be dispensed at a predetermined frequency or intensity.

10. A method of determining the how many days of dispensing are available in a source of material to be dispensed, the source of material being housed in an internal cavity of a dispenser, the dispenser comprising an assembly for dispensing the material to be dispensed, a controller, operatively coupled to the assembly, for determining the time of operation and frequency and/or intensity of operation of the assembly, wherein the controller includes operational parameters selected from the group consisting of:

days of the week during which the material will be dispensed, the time during the day at which the dispenser will begin dispensing for the day, the time during the day at which the dispenser will stop dispensing for the day, and the frequency and/or intensity of dispensing;

wherein the method of providing a “

day count”

indicative of the number of days remaining for which there is material to be dispensed comprises the steps of;

determining a total score representative of the total amount of material available to be dispensed; and

for the first day that the dispenser is operational;

(a) dividing the total score by the dispensing time per day for a selected set of operational parameters; and

(b) rounding the resulting quotient down to the next whole number;

for each successive day that the dispenser is operational;

(a) subtracting, from the total score, the dispensing time per day from the previous day, so as to compute a new “

total score;

”

(b) dividing the new total score by the dispensing time for a successive day for a selected set of operational parameters; and

(c) rounding the resulting quotient down to the next whole number.

11. The method as claimed in claim 10, including the step of displaying the “

day count”

on a display on the dispenser.

12. The method as claimed in claim 10, including a remote control operatively coupleable to the dispenser;

wherein the method comprises the further step of displaying the “

day count”

on a display on the remote control.
