Push-button for a system for dispensing a product under pressure

摘要

A pushbutton for a system for dispensing a pressurized substance, the pushbutton including a body having a housing provided with an anvil around which a spray nozzle is mounted so as to form a substance dispensing path between the housing and a swirl array including a swirl chamber provided with a dispensing port as well as at least one supply duct for the chamber, the swirl chamber being defined by a side surface having a frusto-conical shape relative to which the supply duct(s) extend(s) in a transverse plane, the side surface tapering from an upstream end into which the downstream end of the supply duct(s) tangentially extends, to a downstream supply opening of the dispensing port, the dispensing port having an outlet size that is equal to the internal size of the downstream opening.

主权项

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.
