Adjustable and sealable jet nebuliser for bottles able to be elastically deformed by squeezing

An adjustable and sealable jet nebuliser for bottles able to be elastically deformed by squeezing, able to be mounted on the mouth of the neck (2) of a bottle (3) and comprising a conduit for the liquid (17), connected, by means of a check valve, to a suction tube (24) which draws in a liquid contained inside the bottle (3) under a volume of air, and a conduit for the air (16) communicating with said volume of air of the bottle (3), surrounding the conduit for the liquid (17) and ending, together with the conduit for the liquid (17) into a mixing chamber communicating with the exterior through a central exhaust orifice (29), characterised in that:

• said conduit for the air (16) and said conduit for the liquid (17) are obtained coaxially in a cylindrical body (4), having, in its portion projecting from the mouth of the bottle neck (2), an external thread (14) to be engaged with an internal counter-thread (37) obtained in a screw-on cap (28), provided with the central exhaust orifice (29), the screw-on cap (28) having a cylindrical wall (30), to be inserted between the conduit for the air (16) and the conduit for the liquid (17), to create a mixing chamber (33) with variable geometry;
• and said conduit for the liquid (17) having on its upper end an arm (26) oriented upwards, bearing, at its free end, a tip cap (27), able to be inserted into said central exhaust orifice (29) whilst the screw-on cap (28) is screwed onto the cylindrical body (9), until sealing the nebuliser.
