| 20080315006 | Diffusion device - A diffusion device includes a housing and an opening in the housing adapted for insertion of a container having an active material therein and a wick extending therefrom. The device further includes a heater disposed in a rear portion of the housing and spaced from the wick when a container is inserted into the housing. A vent is disposed in a front portion of the housing. An active material diffusion-interference member is disposed directly above and axially aligned with the wick when the container is inserted into the device, wherein the diffusion-interference member inhibits diffusion of the active material from the housing such that heat generated by the heater is trapped around the wick, thus increasing volatilization and dispersion of the active material from the diffusion device as compared to a diffusion device that does not have a diffusion-interference member. | 12-25-2008 |
| 20100176213 | Volatile material dispenser - A volatile material dispenser includes an upper housing with an opening extending therethrough and a lower housing with an opening extending therethrough, wherein the upper housing is secured to the lower housing to define a cavity therebetween. Electrical circuitry is disposed within the cavity, wherein the electrical circuitry includes a heater and a USB interface that extends from the upper and lower housings. Further, a volatile material cartridge is disposed within the cavity. The dispenser is adapted to dispense volatile material from the volatile material cartridge through the openings in the upper and lower housings in a passive mode and an active mode, wherein the USB interface is coupled to a power source to energize the heater in the active mode. | 07-15-2010 |
| 20110024519 | DIFFUSION DEVICE - A diffusion device includes a housing and an opening in the housing adapted for insertion of a container having an active material therein and a wick extending therefrom. The device further includes a heater disposed in a rear portion of the housing and spaced from the wick when a container is inserted into the housing. A vent is disposed in a front portion of the housing. An active material diffusion-interference member is disposed directly above and axially aligned with the wick when the container is inserted into the device, wherein the diffusion-interference member inhibits diffusion of the active material from the housing such that heat generated by the heater is trapped around the wick, thus increasing volatilization and dispersion of the active material from the diffusion device as compared to a diffusion device that does not have a diffusion-interference member. | 02-03-2011 |
| 20110038761 | Wearable Chemical Dispenser - Wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human are disclosed. They are of the type that are clipped onto a belt or the like, and use a powered fan to dispense active. They are configured with fan rotor arrangements to minimize power use while still achieving acceptable air flow rates. These changes permit use of smaller batteries and more compact arrangements for battery positioning. This in turn permits a much more compact and lightweight construction to achieve the desired results. The devices are also provided with a rotatable clip structure to render use of the device more comfortable when the user is seated and to provide greater control over the direction of the dispensing. Further, they are provided with modified lids to facilitate active refill replacement. | 02-17-2011 |
| 20120012668 | Volatile Material Dispenser and Method of Attaching a Refill or Refills to Same - A method of attaching a refill to a volatile material dispenser includes the step of providing a volatile material dispenser that includes a housing, a first implement that attaches a refill containing a volatile material to the housing, and a second implement that attaches the refill to the housing, wherein the first and second implements include different features. The method further includes the step of attaching the refill in a first orientation to the volatile material dispenser, wherein in the first orientation, the first implement retains the refill. Still further, the method includes the step of attaching the refill in a second orientation different than the first orientation to the volatile material dispenser, wherein in the second orientation, the second implement retains the refill. | 01-19-2012 |
