A nebuliser micro-pump ( 1 ) provided with an element ( 2 ) for covering and triggering its dispensing push-button ( 3 ), has an elongated body ( 5 ) with central axis (x), whereon is mounted a dispensing push-button complete with a tube ( 4 ) for orienting the spray, rotatable around the axis. The element has a lower fixed half-shell ( 12 ) integral with the elongated body and a lower half-shell ( 17 ) movable around a hinging axis (y) that is perpendicular to the central axis and offset relative thereto at the opposite side from the tube. The upper half-shell has a protuberance ( 20 ) acting on the dispensing push-button in the rotation of the movable half-shell relative to the fixed half-shell according to the arrow (W). The half-shells ( 12, 17 ) have respective through openings ( 15, 23 ) wherefrom simultaneously projects the tube in two angular positions, one non operative and the other one operative for the micro-pump.
