Patent ID: 8603397

Claim:
A volatile composition dispenser configured to be used in a vehicle, the volatile composition dispenser comprising: a housing; a fan positioned at least partially within the housing, wherein the fan is configured to be intermittently activated to move a volume of air; a controller in electrical communication with the fan and positioned within the housing; and a replaceable unit configured to be one of attached to the housing and positioned at least partially within the housing, the replaceable unit comprising a volatile composition container comprising: a volatile composition in at least partially a liquid phase and configured to evaporate into a vapor phase, a high surface area material; an inner wall; at least two projections extending into the volatile composition container from the inner wall, wherein the at least two projections are each configured to engage the high surface area material to maintain the high surface area material at a distance away from the inner wall; and at least one space defined intermediate the inner wall and the high surface area material to receive the vapor phase volatile composition; a first orifice configured to receive the volume of air from the fan; and a second orifice configured to expel at least a portion of the volume of air and a portion of the vapor phase volatile composition from the volatile composition container to the atmosphere, wherein the first orifice and the second orifice each have a cross-sectional area in the range of about 0.007 cm 2 to about 0.50 cm 2 ; wherein the fan is configured to intermittently force the volume of air at least partially through the volatile composition container to expel at least most of the vapor phase volatile composition into an atmosphere; and a power source in electrical communication with the controller.
