A fume collecting arrangement is provided comprising vents (36) provided adjacent the mouth or opening (28) of the container (26) and means operable to draw in air, with fumes escaping from the container (26), whilst the closure (32) is in the open position, and to pass the air carrying the fumes to treatment means or to a disposal outlet.
