Abstract

An atomiser device for dispensing a fragrance composition into the air. The device comprising an ultrasonic atomiser and a refill comprising a fragrance composition. The invention also includes a method of fragrancing the air utilising the atomiser device. A refill of the fragrance composition suitable for use in the atomiser device.

First claim

The invention claimed is:

1. An atomiser adapted to dispense a fragrancing liquid comprising a fragrance composition; the atomiser comprising
an outer housing;
an orifice plate and piezo electric element;
a liquid reservoir, comprising the fragrancing liquid to be atomised, the fragrancing liquid comprising the fragrance composition and a carrier solvent; and,
a liquid transport member;
wherein the liquid transport member extends from within the liquid reservoir to abut the orifice plate; and
wherein the liquid transport member is a wick comprising paper, cotton, nylon, or polypropylene which is substantially contained within the liquid reservoir and both the wick and liquid reservoir are readily detachable together from the atomiser; and
wherein the fragrancing liquid comprises 2-25% wt. of the fragrance composition, and,
75-98% wt. of the carrier solvent which comprises at least 50% wt. branched chain alkanes.

2. The atomiser of claim 1 wherein wick comprises polypropylene.

3. The atomiser claim 1 , wherein the fragrancing liquid comprises at least 5% by weight of the fragrance composition.

4. The atomiser of claim 1 , wherein the carrier solvent is greater than 99% by weight the branched alkane solvent.

5. The atomiser of claim 1 , wherein the branched chain alkane carrier solvent comprises C 11 -C 16 carbon compounds.

6. The atomiser of claim 1 , wherein the branched chain alkane carrier solvent has a boiling point of between 240 and 270° C.

7. The atomiser of claim 1 , wherein the branched chain alkane carrier solvent has a molecular weight of between 170 and 200.

8. The atomiser of claim 1 , wherein the carrier solvent consists of the branched chain alkanes.

9. The atomiser of claim 1 , wherein the atomiser comprises at least one battery.

10. The atomiser of claim 1 , wherein the atomiser requires between 1 and 12 volts to operate.

11. The atomiser of claim 1 , which additionally comprises control circuitry operative to provide regular activation of the device over time.

12. A method of fragrancing the air comprising activating the atomizer of claim 1 .

13. A refill for the atomizer of claim 1 adapted for use as the liquid reservoir comprising;
the fragrancing liquid comprising the
fragrance composition and the carrier solvent; and
the wick, extending from inside the refill to the outside.

14. The refill of claim 13 wherein the fragrancing liquid comprises at least 5% by weight of fragrance composition.

15. The refill of claim 13 , wherein the carrier solvent is comprises at least 60% by weight of branched chain alkanes.

16. The refill of claim 13 , wherein the carrier solvent consists of the branched chain alkanes.

17. The refill of claim 13 , wherein the branched alkanes comprise C 11 to C 16 branched chain alkanes.

18. The refill of claim 13 , wherein the branched chain alkane carrier solvent has a boiling point of between 240 and 270° C.

19. The refill of claim 13 , wherein the branched chain alkane carrier solvent has a molecular weight of between 170 and 200.

20. The atomizer of claim 1 wherein the wick is between 4 cm and 14 cm in length.
