Abstract (en)
[origin: WO2018146434A1] The invention relates to a spray head for a fluid product, comprising: a body (1) forming a compartment (14) in which a core (16) extends; and a nozzle (2) fitted into the compartment (14) around the core (16), and forming a spray opening (O) having a chamber outlet diameter D3 with a chamber outlet cross-section S3. The core (16) and the nozzle (2) define therebetween, from upstream to downstream: multiple swirl channels (T) having a channel length L1; and a swirl chamber (C) having a chamber inlet diameter D2 and a chamber inlet cross-section S2, the dispensing opening (O) forming an outlet for the swirl chamber (C), characterised in that 30% of S2 ≤ S3 ≤ 55% of S2, and preferably S3 is equal to approximately 42% of S2.
