Abstract:
1. A push-button for a dispensing system for a product under pressure, said push-button comprising: a body having a well for mounting on a feed tube of the product under pressure; and a housing in communication with said well, said housing including an anvil around which a spray nozzle is mounted in such a way as to form a dispensing path for the product between said housing and a vortex unit, the vortex unit comprising a vortex chamber, including a dispensing orifice, and at least one supply channel of said vortex chamber; said push-button being characterised in that said vortex chamber is delimited by a lateral surface having a conical geometry and an upstream end to which the at least one supply channel extends in a transverse plane located downstream of the anvil, the plane being perpendicular to a dispensing axis of the vortex chamber, said lateral surface converging from the upstream end, where the product tangentially exits a downstream end of the at least one supply channel to put the product in rotation about the upstream end of said lateral surface, towards a downstream opening of said vortex chamber for supplying the dispensing orifice, said dispensing orifice having an outlet diameter which is equal to an internal diameter of said downstream opening.
