Abstract: A volatile material dispensing system (100) includes a base (104) and a refill (102) attached to the base (104). The refill (102) includes a substrate (108) having a volatile material thereon. The dispensing system (100) further includes a cover (106). In an inactive state, the refill (102) is compressed within the cover (106) and the cover (106) is attached to the base (104) and in an active state, the cover (106) is removed from the base and the refill (102) automatically expands such that the volatile material is released from the substrate (108) and into the ambient environment.

Abstract: 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.

Abstract: A dispensing device for release of an air treatment material includes a semi-permeable substrate having a mesh size between about 15 strands per cm to about 79 strands per cm and a support component for supporting the semi-permeable substrate. The dispensing device releases the air treatment material at a rate of at least about 0.05 mg/hr at about 25° C.

Abstract: 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.

Abstract: A dispensing system includes a refill having a reservoir for containing a volatile material. A permeable membrane is disposed over the reservoir and allows the volatile material to be released therethrough. The dispensing system also includes a housing adapted to retain the refill and a manual drive mechanism, which is in communication with the refill. Actuation of the manual drive mechanism causes the refill to rotate more than 180° about a longitudinal axis.

Abstract: Disclosed are pyrethrin-based insect control formulations which have been formulated to reduce wick clogging in dispensers which use heaters to drive an insect control active from the wick. Pyrethrum extract is mixed with an acetylenic compound, such as prallethrin or 3,5-dimethylhex-1-yn-3-ol, and a terminal diene compound such as myrcene or 1,3 hexadiene. Wick clogging side effects from using the pyrethrum are thereby suppressed.

The devices are of the type that are clipped onto a belt or the like, and use a powered fan to dispense active. Air flow is directed through a substrate and adjacent to a useful life indicator to improve reliability of the useful life indicator.

Abstract: A method of dispensing a volatile active into the surrounding environment includes the steps of providing a fragrance dispenser having a housing, a fan disposed within the housing and having a airflow director, first and second chambers disposed within the housing, and first and second fragrances disposed in the first and second chambers. The first and second chambers include first and second shutters covering first and second outlets, and first and second heaters, respectively.
