Patent ID: 7850046

Claim:
A nebuliser micro-pump provided with an element for covering and triggering its dispensing push-button, in which a micro-pump ( 1 ) has an elongated body ( 5 ) with central axis (x), whereon is mounted a dispensing push-button ( 3 ) complete with a tube ( 4 ) for orienting the spray, said elongated body ( 5 ) being provided with means for connecting, on one side, with a bottle ( 100 ) containing liquid to be nebulised and, on the other side, with a trigger-like covering and activation element ( 2 ), which is able to conceal the elongated body ( 5 ) and to change the manner of activation of the micro-pump from that in which a force is applied according to the central axis (x) from the top downwards on the dispenser push-button ( 3 ) to that in which a radial force is applied towards the same central axis (x), said trigger-like covering and activating element comprising a fixed part, integral with said elongated body ( 5 ), and a part that is movable relative to the fixed part around a hinging axis (y) that is substantially perpendicular relative to the central axis (x) and offset in axis at the opposite part to the orienting tube, and provided with a protuberance acting on said dispensing push-button ( 3 ) in the rotation of the movable part relative to the fixed part, characterised in that said fixed and movable parts of the covering and activating element ( 2 ) have respective through openings ( 15 , 23 ) wherefrom simultaneously projects said tube ( 4 ) for orienting the spray, said tube being manually rotatable together with the dispensing push-button ( 3 ) around said central axis (x) of the elongated body ( 5 ) in the openings between at least two angular positions: a non operative position, in which the tube ( 4 ) for orienting the spray is delimited closely by said fixed and movable parts of said covering and activating element ( 2 ) and hence is made immovable at least in the direction of the central axis (x), and —an operative position of the micro-pump, in which the tube ( 4 ) for orienting the spray is within a slot that is elongated in the direction of the central axis (x), upwards in the movable part and respectively downwards in the fixed part of said covering and activating element ( 2 ), so that the orienting tube ( 4 ), together with the dispensing push-button ( 3 ) is movable downwards when said covering and activating element ( 2 ) is operated manually.
