A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

A fragrance delivery system which includes a container with reservoir compartment and having an outer wall at least partially formed of a fragrance permeable plastic, the plastic being a thermoplastic elastomer block copolymer having a Volume Resistivity from 1×10.sup.12 to 1×10.sup.20 Ohms.Math.cm and a Water Absorption from 4 to 20%; and a fragrance composition held within the reservoir, the composition being a mixture of low and high volatile perfume ingredients.

A benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each microcell of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, an ionic surfactant, and a benefit agent. Application of an electric field on the microcell layer affects the rate of release of the benefit agent through the porous second electrode layer.

A flameless electric candle having a fan-driven scent diffuser. The candle includes a body portion having a translucent portion and a generally elongated cylindrical shape and housing therein a light emitting device configured to permit its emitted light to be partially visually discernible through the translucent portion. There is below the body portion, a base portion that includes a PCB, a switch, a light emitting device, a power source, a fan oriented to force air in a downwards direction away from the body portion, a pad configured to receive upon a surface thereof a fragrance or scent, openings in a wall of the base portion to allow the forced air scented by the fragrance to escape the base portion. The switch is selectable among a first mode in which the LED and fan are both on, an off mode both the LED and fan are off, and a second mode wherein only one of the LED or fan is on.
