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.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

Methods, devices and systems are described for digitally creating new scents or digitally dispensing gas, vapor, or liquid substances. A device includes a container or replaceable cartridge including one or more chambers containing one or more scented substances; a housing structured to include a compartment to hold the cartridge, an opening to allow the one or more scented or unscented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to deliver a scented substance from the corresponding chamber to the opening for delivering a scent from the one or more scented substances; and an actuator switch arranged in a corresponding transporting channel and rapidly operable to move between an open position and closed position based on an applied signal to selectively allow passage of the scented or unscented substance from the corresponding transporting path.

Described herein are compositions for malodor reduction in various air care applications.

A rotary separation devise deploys a drum with mesh like opening on the cylindrical surfaces and a removable cover or cap for filling in an upright position and removal of product or spent matter in an inverted position. When the drum is loaded with material, and the cover closed, it is rotatable to a horizontal position, and disposed in an outer container. The drum is rotated in the horizontal position to initiate the separation process. The outer container may be formed by the mating engagement at a common rim of an upper and lower vessel that form the sealed container.

A device for generating hydroxyl radicals having: a) at least one container suitable for containing a substance from which hydroxyl radicals are generated; b) at least one conversion unit suitable for generating hydroxyl radicals from that substance; c) a fluid conduction system that allows air to be recirculated inside the device in such a way that part of the air with a mixture of radicals circulates several times before going outside and d) a base having a power supply, a fan, an air inlet and outlet duct from the device, means for electrically supplying the various components of the device and a controller; in which the air inlet and air outlet duct include a mixing vessel before the air outlet of the device, these vessel and conversion unit are independent of each other and can be independently removed from the base.

Device for diffusing volatile substances that comprises a container (1), an upper closing element (2) which closes the opening of the container (1) and a wick (3) jointed to the closing element (2). The container (1) comprises an opening, a reservoir containing a predetermined volume of a liquid volatile substance, and a lower neck (6). The closing element (2) further comprises at least one internal perimetral grove (4), and the lower neck (6) of the container (1) further comprises a groove with no thread pitch (7) in turn comprising protrusions (9) so that the internal perimetral grove (4) and the groove with no thread pitch (7) work together for an adjustment on a fixed pre-determined position of the upper closing element (2) with regards to the container (1).
