Apparatus for dispensing a fine spray of liquid particles comprises a hollow tubular housing (2) and a reservoir pen (9) formed with a nib (15) of absorbent material which is retained within and spaced from the inner wall of the housing (2). The tubular housing (2) includes at one end a nozzle (4) whose interior defines a converging path and at its other end a mouth piece (3) through which air can be caused to flow through the tubular housing and over the pen (9) to the outlet orifice of the nozzle (4). An abutment is provided within the housing (2) for locating the pen (9) within the housing with its absorbent nib (15) at least partially within the boundary of the outlet orifice of the nozzle (4).
