Patent ID: 7159798

Claim:
A nebulising dispenser head ( 1 ; 100 ) for a bottle that is elastically deformable by squeezing, comprising: liquid channel ( 4 ) with first and second ends, the liquid channel connected at the first end to a suction tube ( 6 ) which draws a liquid contained within the bottle ( 2 ) from under a volume of air, and the liquid channel terminating, at the second end, with a liquid nozzle ( 7 ) disposed in a mixing chamber ( 70 ), the mixing chamber defined by a terminal element facing said nozzle; an orifice ( 31 ) for discharging the liquid outwards from the mixing chamber; and an air channel ( 5 ) communicating with said volume of air of the bottle ( 2 ), the air channel ( 5 ) surrounding the liquid channel ( 4 ) and merging into said mixing chamber ( 70 ) wherein, said liquid channel ( 4 ) and said air channel ( 5 ) are formed in a block ( 10 ) of said dispenser head ( 1 ; 100 ) as a ribbed tubular segment ( 40 ) externally ribbed with ribs ( 42 ), said air channel ( 5 ) comprises a wall ( 50 ) surrounding said liquid channel ( 4 ), said wall ( 50 ) defines a tubular compartment ( 51 ) substantially coaxial to said ribbed tubular segment ( 40 ), thereby forming a ribbed tubular compartment, said wall ( 50 ) includes an opening ( 52 ) for communication with said volume of air of the bottle ( 2 ), said terminal element includes an ejection tip ( 3 ) with a tubular element ( 30 ) having a cavity shaped to axially narrow outwards in said discharge orifice ( 31 ) and terminate with a diverging segment ( 32 ), said ejection tip ( 3 ) is inserted with a proximal portion thereof into said ribbed tubular compartment ( 51 ) thereby defining said mixing chamber ( 70 ), said ejection tip includes a sleeve ( 33 ) externally coaxial to said tubular element ( 30 ) and integrally provided with an abutment ( 34 ) defining a depth of insertion of the ejection tip into said ribbed tubular compartment ( 51 ) of the block ( 10 ), and said ejection tip further includes a sealing door ( 8 ) integrally hinged at a distal part ( 35 ) of said sleeve ( 33 ), the sealing door ( 8 ) being rotatable by 180° from an open position to a closed position of said discharge orifice ( 31 ).
