A nasal dispenser head (10) for a fluid dispenser device, said head (10) comprising an expulsion channel (11) terminating in a dispensing orifice (12), an insert (20) being placed in said expulsion channel (11), the downstream end (21) of said insert (20) in the flow direction of the fluid co-operating with the downstream end portion of said expulsion channel (11) to define a spraying profile (13, 14), the head being characterized in that said downstream end (21) of said insert 20) and said downstream end portion of said expulsion channel (11) are both frustoconical, forming a frustoconical spraying profile (13, 14), said insert (20) occupying substantially all of the volume of the expulsion channel (11) so as to define a narrow expulsion channel (11).
An elongated nasal fluid dispenser head for spraying a fluid, comprising:
- an elongated external member configured to be manually inserted into a nasal passage for praying a fluid inside the nasal passage;
- an expulsion channel extending within the elongated external member and terminating in a dispensing orifice;
- an insert placed in the expulsion channel, a downstream end of said insert in the flow direction of the fluid co-operating with a downstream end portion of said expulsion channel to define a spraying profile;
- and
- wherein the downstream end of said insert and the downstream end portion of the expulsion channel are both frustoconical, forming a frustoconical spraying profile;
- and
- wherein the insert occupies substantially all of the volume of the expulsion channel so as to define a narrow expulsion channel.
