The discharge device comprises a member having a plurality of liquid flow openings, an eductor tube, a liquid flow path from the eductor tube to the member with the plurality of liquid flow openings and a valve positioned in the liquid flow path. The valve is movable between a blocking position and a discharge position. The valve is operative in the blocking position to block the liquid flow path and is operative in the discharge position to unblock the liquid flow path. Further, a cap member having a discharge orifice which is larger than any of the plurality of openings is mounted over the member having the plurality of openings. The device produces a fine spray mist. However, the device can also be used to produce a foam by placing a screen over the orifice.
