Abstract

An air freshener is configured to be carried by a power outlet of an automobile. The air freshener includes a scent capsule disposed in a housing. A heat source is disposed in the housing adjacent and opposing a permeable membrane of the scent capsule. The heat source is configured to heat the fragrant material in the scent capsule and accelerate permeation of the fragrant material through the permeable membrane of the sent capsule. A hatch is pivotally coupled to the housing and substantially contained within a hatch cavity with an outer surface that is substantially flush with an exterior of the housing in a closed position. The hatch can include a capsule cavity therein, carrying the scent capsule, and facing an interior of the housing in the closed position.

b) the scent capsule removably disposed in the capsule cavity of the hatch.

12. A device in accordance with claim 1, further comprising:

a) a hatch coupled to the housing and displaceable with respect to the housing,

b) an exterior window in an outer surface of the hatch; and

c) the scent capsule having a dome that is at least translucent so that the fragrant material is visible through the dome and the exterior window of the hatch.

13. An air freshener device configured to be carried by a power outlet of an automobile, the device comprising:

a) a housing with a stem and a head with a cavity therein, the stem sized and shaped to be inserted into the power outlet of the automobile;

b) a hatch cavity in the head of the housing;

c) a hatch pivotally coupled to the housing and substantially contained within the hatch cavity with an outer surface that is substantially flush with an exterior of the housing in a closed position, and with a capsule cavity therein facing an interior of the housing in the closed position; and

d) a scent capsule removably disposed in the capsule cavity of the hatch and carried by the hatch as the hatch pivots, the scent capsule having a chamber containing a fragrant material and having a permeable membrane through which a fragrance of the fragrant material can permeate over time, the permeable membrane facing the interior of the cavity in the closed position.
