Abstract
A spray nozzle for a system for dispensing a pressurized product is provided with a pushbutton. The nozzle includes a dispensing orifice and a vortex chamber emerging on the dispensing orifice. The chamber includes a conical part defined by a conical side surface. The conical side surface converges from an upstream end toward a downstream supply end of the dispensing orifice. The nozzle further includes at least one supply channel of the vortex chamber, each supply channel emerging in the upstream end of the conical part, the conical side surface having at least one stepped portion provided with multiple levels.

A spray nozzle adapted for use with a system for dispensing a pressurized product provided with a pushbutton, the nozzle comprising:
- a dispensing orifice and a vortex chamber emerging on the dispensing orifice, the chamber including a conical part defined by a conical side surface, said conical side surface converging from an upstream end toward a downstream supply end of the dispensing orifice, the nozzle further comprising at least one supply channel of said vortex chamber, the at least one supply channel emerging in the upstream end of the conical part, the conical side surface having at least one stepped portion provided with one or more levels, wherein the nozzle comprises at least one continuous portion developing along the conical side surface from the upstream end to the downstream supply end, and wherein said one continuous portion overhangs the at least one adjacent stepped portion in an inward radial direction along the entire length of the conical side surface.
A system for dispensing a pressurized product, comprising
- a spray nozzle adapted for use with a system for dispensing a pressurized product,
- a pushbutton, the nozzle being arranged on the pushbutton,
- wherein the spray nozzle comprises a dispensing orifice and a vortex chamber emerging on the dispensing orifice, the chamber including a conical part defined by a conical side surface, said conical side surface converging from an upstream end toward a downstream supply end of the dispensing orifice, the nozzle further comprising at least one supply channel of said vortex chamber, the at least one supply channel emerging in the upstream end of the conical part, the conical side surface having at least one stepped portion provided with one or more levels, wherein the nozzle comprises at least one continuous portion developing along the conical side surface from the upstream end to the downstream supply end, said one continuous portion overhangs the at least one adjacent stepped portion in an inward radial direction.
