wick 56 the plate 58 has vent holes 60 to allow air to circulate about the wick whilst the present invention is particularly advantageous for use with dispenser bottle assemblies incorporating an air freshener dispenser 44 non symmetrically disposed on one side of the bottle the nature of the air freshener dispenser itself does not form a part of the present invention and other air freshener dispensing arrangements could be adopted for example an air freshener dispenser which holds a solid air freshener composition could be used indeed the invention is not limited to dispensers and dispenser bottle assembles in which an air freshener dispenser is non symmetrically disposed about the bottle but can be adopted in dispensers which have a symmetrical air freshener arrangement or which do not incorporate an air freshener dispenser at all a cylindrical projection 62 projects outwardly downwardly when the bottle is upright from the base 30 of the bottle the projection has a longitudinal axis x which in this embodiment is concentric with a longitudinal axis of the remainder of the bottle the projection has a first radial lip 64 at its end distal from the base 30 and a second radial lip 66 at is end proximal the base 30 the first and second radial lips 64 66 have similar outer diameters which are larger than the outer diameter of a central portion 67 of the 62 projection in between the two lips the drive member 26 comprises an annular disc 68 which is mounted about the projection 62 of the bottle it has an internal diameter which is a close sliding fit about the second radial lip 66 proximal to the base 30 of the bottle the.
