Fragrance dispensers with features that are capable of reducing wastage of fragrance, or of conserving fragrance, are disclosed. Such a fragrance dispenser may have a configuration that collects fragrance that is expelled from the fragrance dispenser, but has not vaporized or atomized sufficiently to dissipate into the environment, as well as fragrance that condenses immediately after it has been expelled from the fragrance dispenser. A spill-resistant bottle that may be used with a fragrance dispenser has a shape that orients an opening of the bottle in a somewhat upward orientation to prevent fragrance from spilling out when the bottle is tipped over. Fragrance dispensers with configurations that generate vortices to deliver fragrance into the surrounding environment are also disclosed.

A heater arrangement for a volatile material dispenser includes a cylinder defining an opening and a resistor embedded in the cylinder. The dispenser further includes a housing configured to receive a refill containing a volatile material and a wick. The housing includes a first cavity configured to support the heater arrangement. Further, the dispenser is configured such that, when the refill is received within the housing, the opening receives the wick therein so that a radial gap is formed between the heater arrangement and the wick.

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.

[Object] To propose a novel and improved fragrance material holding member and fragrance providing device that can improve persistence of a fragrance material while avoiding an increase in the size of the device. [Solution] Provided is a fragrance material holding member including: an airflow passage through which air supplied from an airflow source passes, the airflow passage being provided to penetrate the fragrance material holding member; and a holding space that branches from the airflow passage and holds a fragrance material.

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.

Described is a scent producing assembly having a self-contained module comprising an absorptive matrix infused with a volatile composition and a housing. The housing may include a receptacle shaped to receive the module, wherein the housing has a stowed position and a deployed position. In the stowed position, the receptacle may be contained within an interior of the housing. In the deployed position, the receptacle may be displaced out of the housing. The receptacle may move along an arcuate path when the receptacle is moved between the stowed and deployed positions.

A device for diffusing volatile substances includes a container containing a liquid with the volatile substances, a base element that closes the container, and a wick that is impregnated with the volatile substances. The base element includes an internal channel in which the liquid containing the volatile substances is deposited. A part of the wick placed in the internal channel is impregnated with the liquid containing the volatile substances located in the internal channel.

A scent distribution device having a spherical housing and having one or more internal cavities in communication with a plurality of wicking members. The wicking members dispersed across the exterior of the housing for the distribution of a scent agent. The device including a harness engaged with an axis of the housing, wherein the housing rotates along the axis for rolling across a surface. The device further including a lead line and segregated and compartmentalized storage container.

The device for the diffusion of volatile substances comprises a container (1), which holds a liquid with the volatile substances in it, and which has an opening (9), for communication from the inside of the housing (6) to the outside; a cover (2) which can be attached to the container (1) to close the opening (9), a diffusion wick (4) for the controlled diffusion of the volatile substances, one end (13) of which protrudes from the cover (2); and a cap (5) which covers the end (13) of the diffusion wick (4) which protrudes from the cover (2), the container (1), the cover (2), the diffusion wick (4) and the cap (5) being made of the same plastic material. It thus makes it possible to provide more efficient recyclability in accordance with currently existing methods.

Methods, systems, and devices relating to an electronic scented candle that is convenient to use and enables rapid generation and dissipation of scented materials are described. One electronic candle device includes a shell that has a through hole, a flame element protruding through the through hole, an installation lid including a locking base to allow removable coupling of a fragrance container, a scent chamber including a locking clip, a first channel, a second channel, a third channel, and a fourth channel. The scent chamber is removably coupled to the locking base by the locking clip, and an air pump provided to supply pressurized air.
