Liquid dispensing apparatus comprises a tubular casing having at one of its ends a mouthpiece and an elongate cap, and at the other of its ends a nozzle having an orifice in communication with an expansion chamber bounded by sides which diverge away from the orifice. A liquid source including an elongate body and an absorbent nib (e.g. a felt-tipped pen) is located within the casing with side surfaces of the pen body spaced from internal was surfaces of the casing to define an air flow passageway therebetween. First and second stop means are provided within the casing against the first of which a surface of the elongate body can abut to position the nib of the liquid source within or in close proximity to the nozzle orifice, and against the second of which a rearward end of the elongate body can abut to position the nib of the liquid source in a relatively airtight manner into one end of the elongate cap. The other end of the elongate cap is closed. Thus the liquid source can selectively be positioned with its nib within or in close proximity to the casing nozzle or with its nib effectively sealed within the elongate cap when the apparatus is not in use. |
