First Claim
Patent Images
1. A method of dispensing a volatile composition, the method comprising the steps of:
- providing a volatile composition dispenser comprising a replaceable unit that is releasably connected with the volatile composition dispenser, the replaceable unit comprising a power source, a volatile composition container comprising the volatile composition in at least partially a liquid phase, and a high surface area material contained within the volatile composition container, wherein the high surface area material comprises at least one surface;
providing a fan powered by said power source and in fluid communication with said volatile composition container;
evaporating a portion of said volatile composition within said volatile composition container;
using said fan to intermittently force a volume of air at least partially through said volatile composition container to expel at least most of the evaporated portion of said volatile composition from said volatile composition container at a flow rate of about 2 cm3/second to about 20 cm3/second.

7. A method of dispensing a volatile composition, the method comprising the steps of:
-
providing a volatile composition dispenser comprising a housing and an actuator disposed within the housing, the volatile composition dispenser comprising a replaceable unit connected to the housing, wherein the replaceable unit comprises a power source, a volatile composition container comprising the volatile composition, and a high surface area material contained within the volatile composition container, wherein the actuator is in fluid communication with the volatile composition container and electrical communication with the power source, wherein a gap is formed between the volatile composition container and the high surface area material, wherein at least a portion of the gap is about 0.5 mm to about 3 mm; evaporating a portion of said volatile composition within said volatile composition container; and using said actuator to intermittently force a volume of air at least partially through said volatile composition container to expel the evaporated portion of said volatile composition from said volatile composition container. - View Dependent Claims (8, 9, 10, 11, 12, 13)
