20120305573 | Self-Righting Containers - An open self-righting container comprising a shell with a bottom truncated non-spherical Gomboc-like surface and a wall projecting upwardly therefrom, an interior cavity, a bottom rest surface at a stable equilibrium point of the shell, and a top opening opposite the rest surface where the interior of the shell may include a meltable solid fuel fitted with a wick. | 12-06-2012 |
20120305574 | Self-Righting Container - An open self-righting container comprising a convex shell with an outer truncated non-spherical Gomboc-like surface, an interior cavity, a rest surface at a stable equilibrium point of the shell, and an opening opposite the rest surface where the interior cavity may include a meltable fuel fitted with a wick. | 12-06-2012 |
20130323292 | Clog Resistant Insect Control Formulations Containing Pyrethrin, An Acetylenic Compound, And A Hydrocarbon Diene - 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. | 12-05-2013 |
20140027530 | Dispensing Device - 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. | 01-30-2014 |
20150075445 | Portable Area Repellent Device - 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 an air treatment chemical to exit the interior space of the housing. A substrate positioned within the housing bears an air treatment chemical. A power supply mounted within the housing powers a motor within the housing. 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. | 03-19-2015 |
20150078921 | AIR TREATMENT CHEMICAL DISPENSER HAVING ANGLED DISPERSION OF CHEMICALS - 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. | 03-19-2015 |
20150115060 | 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 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. | 04-30-2015 |
20150130089 | VOLATILE MATERIAL DISPENSING SYSTEM AND METHOD OF USE - 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. | 05-14-2015 |
