摘要:
A device for emitting volatile compositions comprising a capillary element, a channel in fluid communication with the capillary element, an emitting orifice having a forward tilt from about +5 degrees to less than about +90 degrees, and a decoupled piezoelectric actuator for emitting the volatile composition through the emitting orifice. In some embodiments, the device is a plug-in air freshener and reduces surface deposition and improves scent noticeability through improved containment of perfumes during the rest period.

摘要:
A liquid particle emitting device comprising a first reservoir formed of a perforated top plate comprising at least one aperture; and a base plate opposite said perforated top plate, wherein said perforated top plate and said base plate form the first reservoir comprising an inner volume. Within the inner volume of the first reservoir is at least one deflecting member.
摘要:
A delivery system and methods for generating droplets of liquid active materials, such as a perfume, air freshener, insecticide formulation, and volatile materials, to the atmosphere by means of a electromechanical transducer. The electromechanical transducer employs a first period of activation and a second period of deactivation to increase the distribution of volatile materials contained within the liquid active materials to the atmosphere and reduce the hedonic habituation of the user. The electromechanical transducer is configured to improve flow rate and decrease deposition of the droplets on to nearby surfaces.
摘要:
An actuating device including a load and an integrated electronic control circuit comprising a microcontroller and at least one passive component. The microcontroller performs the dual function of providing a control signal to generate sufficient power to actuate a load and a drive signal to drive the load.
摘要:
Perfume compositions having functional perfume components for aiding in perfume evaporation. The functional perfume components have a Kovat's index in the range of 900-1400 and an ODT of greater than about 1 ppb. In one embodiment, the functional perfume component may be present in an amount from at least about 10% by weight of the composition. In another embodiment, the composition containing a function perfume component is substantially free of a VOC.
