Abstract: A liquid dispenser includes a housing configured to receive a liquid supply cartridge, and a reservoir disposed in the housing that holds a volume of the product. The reservoir includes an access port for receiving the liquid supply cartridge and placing the liquid supply cartridge and the reservoir in communication. A dosing tank is connected to the reservoir and configured to hold a metered volume of the product. A control valve is movable between an opened position and a closed position, wherein when the control valve is in the opened position, product in the dosing tank is permitted to flow from the liquid dispenser and product flow from the reservoir to the dosing tank is prevented, and when the control valve is in the closed position, product in the dosing tank is prevented from flowing from the liquid dispenser and product flow from the reservoir to the dosing tank is permitted.

Abstract: A fragrance dispenser comprises a ceramic outer shell containing a gel composition. The ceramic can be greenware, and can be impregnated with a fragrance, such as in the form of a volatile oil. The gel composition can contain fragrance or deodourisers that can diffuse out of the gel and infuse the surrounding ceramic, from which it can be released into the air. The ceramic cartridge can have indentations to allow it to be retained in a desired location; these can permit the attachment of a plastic mounting clip having a plurality of flexible arms that slot into the indentations to grip and hold the cartridge in place. This mounting clip could then be used to attach the cartridge to suitable surfaces such as a bathroom wall or the interior of a dispenser housing. Furthermore, the cartridge can have a locating recess on one or more of its sides, to receive a mounting post and thereby position the dispenser accurately and inhibit dislodgement.

Abstract: A dispenser capable of dispensing a fluid via a vertically-oriented piezo device comprises a reservoir containing a fluid to be dispensed, an outlet at a base portion of the reservoir, leading to a dispensing port that comprises a piezo element drivable to vibrate and thereby dispense fluid from the dispensing port, a bleed tube communicating at one end with the dispensing port, extending therefrom to a location above the dispensing port, and including a selectively closeable valve, and a source of below-atmospheric pressure to the portion of the reservoir above the fluid. Embodiments of refills suitable for such a dispensing apparatus are also described.
