A refill cartridge for a volatile composition includes a reservoir, a volatile composition within the reservoir, and a composite membrane in fluid communication with the reservoir. The composite membrane includes a barrier layer having a thickness of less than about 10 &#x3bc;&#x3b7;&#x3b9; and at least one support layer in contact with the barrier layer, the support layer having a thickness of at least about 10 um. The volatile composition is transported from the reservoir across the composite membrane at a flux of between 1 and 100 g/(m2-hr) at about 25&#xb0; C. and about 101 kPa.

Composite membrane

A refill kit for a device to dispense an air treatment chemical includes a substrate supported on a frame. The substrate is in the form of a puck, and includes sand, a binder, and an air treatment chemical. A candle is also provided, which is suitable to heat the substrate.

Candle dispenser

An aerosol dispenser assembly is disclosed that includes a container holding a liquid product and a compressed gas propellant for propelling the liquid product from the container. A design methodology for the actuator body and swirl nozzle insert is disclosed for maintaining a small particle size or Sauter Mean Diameter (D[3, 2]) of less than 48 &#x3bc;m at a suitable spray rate (1.5-2 g/s), while utilizing a compressed gas VOC-free propellant for an air freshener product. As obtaining reduced particle size to compete with LPG propellants may result in a reduced spray rate, it is anticipated that one or more nozzles may be designed into the actuator body to maintain a suitable spray rate.

A device for dispensing an air treatment chemical includes a housing having an inlet for permitting air to enter into an interior space of the housing and an outlet for permitting air mixed with air treatment chemical to exit the interior space of the housing. A substrate positioned within the housing bears the air treatment chemical. A power supply mounted within the housing powers a motor mounted within the housing. The motor is connected to an impeller mounted within the housing. The impeller moves air from the inlet adjacent the substrate to mix the air treatment chemical into the moving air and deliver the mixture of air and air treatment chemical through the outlet to outside of the housing. The housing includes a transitional body defining a convergent-divergent channel for compressing the mixture at the converging section and expanding the mixture at the diverging section.

Air treatment chemical dispenser having angled dispersion of chemicals

Devices for dispensing an air treatment chemical such as insect repellent are disclosed. There is a chimney housing having a side wall defining an internal cavity. There is also a caddy assembly supported by the housing and having an upper caddy frame configured to mount a substrate bearing an air treatment chemical adjacent an upper portion of the housing, and a candle holder coupled to the upper caddy frame and configured to support a candle having a wick adjacent a lower portion of the housing. There is also a substrate bearing air treatment chemical suitable to be supported by the upper caddy frame, and a candle suitable to be supported by the candle holder. A refill kit for such devices is also disclosed. Also disclosed is an embodiment with a sand core bearing the repellent, a heat deflector positioned under the sand core, and a candle positioned under the heat deflector.

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.

Wearable chemical dispenser

Devices dispenser air treatment chemicals in response to heat generated by a candle. Heat transfer elements carry flame heat to an impregnated substrate that is positioned mostly or entirely below the candle. The air treatment chemical vapors are kept away from prolonged direct exposure to flame heat, thereby reducing heat degradation of the active. The candle automatically adjusts heat transfer rates to correct for decreasing amounts of active on the substrate as the substrate sears being used up.

An insert, a system, and a method are provided for dispensing a compressed gas product. The insert includes a swirl chamber, inlet ports to the swirl chamber, and an outlet orifice. The insert has specifically configured parameters relating to the diameter of the swirl chamber, the diameter of the outlet orifice, the length of the outlet orifice, and the depth of the swirl chamber. The insert, system, and method can provide a dispensed compressed gas product with a remarkably constant flow rate and with a remarkably constant particle size.

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 outlet arrangements to minimize power use while still achieving acceptable air flow rates. These changes permit use of smaller power supplies and more compact arrangements for power supply (e.g., battery) positioning. This in turn permits a much more compact and lightweight construction to achieve the desired results.

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 a first timer to account for a passive release rate of the active and a second timer to account for an active release rate of the active. The first time and second timer are in communication with a useful life indicator to provide a signal to a user of the device to indicate when the substrate in the device for containing the active should be replaced.

The motor is connected to a fan mounted within the housing. The fan moves air from the inlet adjacent to the substrate to mix the air treatment chemical into the moving air and deliver the mixture of air and air treatment chemical through the outlet to the outside of the housing.
