Abstract: A volatile material dispenser includes a housing configured to receive a refill containing a volatile material and a wick, the housing including a first cavity supporting a heater arrangement and a second, separate cavity supporting a fan arrangement for dispersing a vapor plume of the volatile material. The first cavity is substantially unobstructed between an upper, interior surface of the housing and an upper surface of the heater arrangement. The housing also includes an aperture through which the vapor plume exits the housing and a plurality of openings through which air from the fan arrangement directs the vapor plume away from the aperture. When a refill is received within the hosing, the upper surface of the heater arrangement is disposed nearer the aperture than a distal end of the wick, and a radial gap is formed between the heater arrangement and the wick.

Abstract: A dispensing device for release of a volatile material includes a base, a drive arm coupled to a pendulum based drive mechanism, and a refill coupled to the drive arm. The refill includes a support base, at least one flange, a substrate coupled with the at least one flange, and a use-up cue.

Abstract: An emanating device includes a substrate with a body having a first portion and a second portion, a foldable member, and first and second hinges along a longitudinal axis of the body and connected to the foldable member. The foldable member is movable between a first state, such that the member is co-planar with the first portion and second portion, and a second state, such that the foldable member is not co-planar with the first portion and the second portion.

Abstract: Volatile material dispensers are disclosed that include a substrate having a first wall portion with a first grasping portion and a second wall portion with a second grasping portion. The first wall portion and the second wall portion are substantially coplanar in a first state. The volatile material dispensers may further include at least one hinge joining the first wall portion and the second wall portion along a central axis and an insect control active. At least one of the first wall portion and the second wall portion is moveable about the central axis to form a configuration in which the first and the second wall portions are substantially not coplanar in a second state. The first grasping portion and the second grasping portion are coaxial with the central axis in the first state and the second state.

Abstract: 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.

Abstract: A method of emitting a volatile material includes the step of programming a volatile material dispenser to include at least two intensity levels, wherein upon initiation of each of the intensity levels for an operating cycle, a resistor is operated at a first percentage of its power rating for a first period of time. Upon selection of a first of the at least two intensity levels and after the first period of time, the resistor is operated at a second percentage of its power rating for a remainder of an operating cycle. Upon selection of a second of the at least two intensity levels and after the first period of time, the resistor is operated at the second percentage of its power rating for a second period of time and, after the second period of time, operating the resistor at a third percentage of its power rating for a remainder of an operating cycle.

Abstract: Dispensers for dispensing an insect control active include a porous substrate impregnated with an insect control active. The porous substrate has a minimal bending moment of about 150 to about 275 g-cm. Upon activation, the dispenser exhibits an effective release rate of the insect control active of about 0.1 to about 0.3 mg/hr.
