A fragrance cartridge 24 comprises a cartridge housing (52, figure 7), a reservoir 56 located within the housing to release a fragrance and a closure arrangement (58, figure 7). An aperture 54 extending through the housing is selectively obstructed by the arrangement. The closure arrangement comprises a seal 62, ideally provided at the aperture, and a closure member 60, ideally in the form of a projection 80 such as a cammed surface, ramped surface and/or pyramidal or triangular prism. The closure member moves between a closed configuration and an open configuration. In the open configuration the closure member is disengaged from the seal permitting release of fragrance through the aperture. In the closed configuration the member sealingly engages the seal, ideally protruding through and extending beyond the aperture, to prevent release of fragrance. A spring 64 may be located between the closure member and the reservoir to bias the closure member in the closed configuration. A vehicle fragrance delivery unit (12, figure 10) having an actuator (96, figure 10) to urge the closure member to the open configuration when the cartridge is received within the unit, and a vehicle including the cartridge or unit, are also claimed.
