Disclosed is a system for diffusing oil. In one embodiment, the disclosed system features an essential oil or aromatic substance diffuser, aroma pads, and a convenient packaging.

A fragrance diffuser has a diffuser element connecting a first reservoir to a second reservoir. As a fragrant oil flows between the reservoirs, the diffuser element becomes saturated with oil and diffuses the fragrance or scent. The diffuser is self-contained, easy to interact with, without creating a mess. The diffuser is relaxing and pleasant to watch as it flows through from one end and drips to the other, releasing one small bubble at a time. It is refillable, transportable, and the intensity of the scent release can be controlled easily by saturating the wood more or less often.

A self-adhering vent cover allows a user to improve the appearance of a vent while facilitating sufficient airflow for the continued use of a heating, cooling, or air-ventilation system. The present disclosure also provides for the distribution of essential oils within an indoor environment via the use of a heating, cooling, or air-ventilation system.

The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.

Vent apparatuses comprise a filter comprising a pleasant scent such that when forced air passes therethrough, the scent on the filter is distributed into the room. Alternatively, a tank and/or reservoir may be disposed adjacent the vent, whereby upon activation a spray of a scent may be introduced into the airstream of the forced air and thereby distributed around the room, or the spray may be forced onto the filter, which may act as a substrate holding the scent thereon such that when forced air passes therethrough. In an alternative embodiment, the vent comprises fan blades that generate electricity from the forced air flowing therethrough for powering electronic devices and/or for charging batteries.

A powered disinfectant dispensing device for providing disinfectants is presented. The powered disinfectant dispensing device allows for an easy distribution of disinfectant to a person. The device is both light weight and efficient while providing a small footprint for storage. The device automatically dispenses liquid disinfectant in an airborne manner. The device has a fan that is utilized to provide wind behind a disinfectant to cause the disinfectant to become airborne and evenly distribute the disinfectant.

A microfluidic delivery device is provided. The microfluidic delivery device includes a housing electrically connectable with a power source. A cartridge is releasably connectable with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in an upward direction relative to horizontal. The microfluidic delivery device also includes a fan that is connected with the housing. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in a first direction to a second direction that is different from the first direction.

Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

A progressive liquid fill capacity indicator located inside a vapor diffusion membrane liquid reservoir that utilizes index refraction matching of liquid contact to components, dyes, and surface tension gradients. This fill capacity indicator is low cost and reliable. It enables users to visually assess readiness and remaining liquid capacity to deliver attraction, masking, and repulsion scent vapors from wearable and stationary devices to repel or attract mosquitos and arthropods.
