Abstract: Scent diffusers (e.g., air fresheners) having adjustable scent diffusion rates may comprise scent intensity adjustment configurations for adjusting the intensity of a fragrance material emitted from the scent diffusers. In certain embodiments, the scent intensity adjustment configuration may take the form of slidable planar scent panels saturated with fragrance composition that may be moved into and out of a hollow body portion. When positioned substantially within the hollow body portion, the scent panels emit fragrance composition at a first rate, and when positioned substantially outside of the hollow body portion, the scent panels emit fragrance at a second rate, faster than the first rate. Alternatively, a scent diffuser may have a body portion containing a scent panel, wherein the body portion has a plurality of ventilation openings to control the rate of fragrance composition diffusion by rotating an adjustment panel to selectively block the ventilation openings of the body portion.

Abstract: A scent diffuser (e.g., air freshener) configured to automatically circulate fragrant air throughout a surrounding environment comprises a powered air circulator configured for circulating air and a fragrance composition throughout the surrounding environment, and a solar cell positioned within a support face of the air circulator. The support face is configured to secure the scent diffuser relative to a support surface and has an open portion configured to allow light to contact the solar cell. The air circulator may comprise a centrifugal fan positioned within the housing and configured to draw air through intake apertures in sidewalls of the housing and to exhaust air and fragrance through an outflow aperture of the housing.

Abstract: An air freshener comprises a scent capsule carried by a housing. The scent capsule comprises a reservoir containing a fragrant material, and with an opening to a cavity therein and covered by a permeable membrane through which a fragrance can permeate, and a releasable seal sealed over the opening and the permeable membrane to resist fragrance release until removed. An absorptive pad is disposed behind the releasable seal between the scent capsule and the housing, and is capable of absorbing the fragrant material that permeates through the permeable membrane.

Abstract: An air freshener comprises a container divided into separate and discrete reservoirs separated by an inner wall. A cap is disposed on the container and covers the reservoirs. First and second different fragrant materials are each disposed in a different one of the separate and discrete reservoirs so that the first and second different fragrant materials are separate and discrete with respect to one another in the container. The first and second different fragrant materials have different fragrances combinable in a synergistic manner. The first and second different fragrant materials each comprise a water based gel. One of the fragrant materials can comprise a neutralizing agent.

Abstract: An air freshener comprises a container divided into an inner cylindrical reservoir and an outer annular reservoir with at least two different fragrant materials with different fragrances. A cap is carried by the container and covers the reservoirs. A sleeve extends from the cap into the container between the reservoirs. The cap is movable axially with respect to the container between a raised position in which the at least two different fragrances are released, and a closed position in which the cap covers the container to resist release of the at least two different fragrances.
