| 摘要 |
The invention relates to a pushbutton comprising a body (1) having a housing (11) provided with an anvil (12) around which a spray nozzle (13) is mounted so as to form a path for dispensing the product between said housing and a swirl assembly comprising a swirl chamber (21) provided with a dispensing orifice (22) and at least two supply ducts (23) for said chamber that are disposed symmetrically with respect to a dispensing axis (D), said chamber being delimited by a lateral surface (24) having a polygonal geometry with respect to which the ducts (23) extend in a transverse plane, the surface (24) converging from an upstream end (25), into which the downstream end of the ducts (23) leads, to a downstream opening (26) for supplying the orifice (22), said orifice having an outlet dimension which is equal to the internal dimension of said downstream opening, the swirl assembly also having a recess (29) formed upstream of and axially facing the chamber (21). |
