The spray profile includes at least one channel that is non-radial and/or non-axial relative to the longitudinal axis (A). The head, the spray orifice, and the spray profile are made as a single piece, the spray profile including a central pin, the internal end of the central pin, arranged inside the hollow body, being of shape that is conical or frustoconical, so as to guide the fluid towards the at least one non-radial and/or non-axial channel, the internal end forming an outlet valve. ## Claims ### Claim 1 A fluid dispenser device, comprising: a syringe having a longitudinal axis for containing a fluid and a piston that slides along the longitudinal axis within said syringe for dispensing the fluid; and a spray head assembled directly on said syringe, said spray head comprising: a hollow body comprising a sleeve that is substantially cylindrical and that extends along the longitudinal axis, and an end wall that is substantially radial and that is provided with a spray orifice; and a spray profile upstream from said spray orifice, said spray profile comprising at least one channel that is non-radial and/or non-axial relative to the longitudinal axis; wherein said head, said spray orifice, and said spray profile are made as a single piece, said spray profile including a central pin located on the end wall and inside of the hollow body, an internal end of said central pin, arranged inside said hollow body, having a conical or frustoconical shape, so as to guide the fluid towards said at least one non-radial and/or non-axial channel, said internal end forming an outlet valve. ### Claim 2 (depends on 1) The device according to claim 1, wherein said spray orifice is of annular shape around said longitudinal axis. ### Claim 3 (depends on 1) The device according to claim 1, wherein said spray orifice is in the shape of a bowl that is symmetrical about said longitudinal axis. ### Claim 4 (depends on 1) The device according to claim 1, wherein said at least one channel extends in sloping and peripheral manner relative to the longitudinal axis, connecting the inside of said hollow body to said spray orifice. ### Claim 5 (depends on 1) The device according to claim 1, wherein said at least one channel is helical and slopes in the radial and axial directions, connecting the inside of said hollow body to said spray orifice. ### Claim 6 (depends on 1) The device according to claim 1, wherein said central pin is connected to said sleeve via a deformable diaphragm made integrally therewith and enabling said central pin to move axially. ### Claim 7 (depends on 1) The device according to claim 1, wherein said outlet valve co-operates with said syringe. ### Claim 8 A fluid dispenser device, comprising: a syringe having a longitudinal axis for containing a fluid and a piston that slides along the longitudinal axis within the syringe for dispensing the fluid through an outlet orifice of the syringe; and a spray head assembled directly on the syringe, the spray head comprising a hollow body comprising a sleeve that is substantially cylindrical and that extends along the longitudinal axis, an end wall that is substantially radial and that is provided with a spray orifice; and a spray profile upstream from the spray orifice, the spray profile comprising a channel that is at least one of non-radial or non-axial relative to the longitudinal axis; the spray profile comprises a central pin located on the end wall and inside of the hollow body, an internal end of the central pin is arranged inside said hollow body and has a conical or frustoconical shape so as to guide the fluid towards the channel, the internal end forming an outlet valve in cooperation with the outlet orifice of the syringe; and the spray head, including the spray orifice and the spray profile with the central pin are made as a one-piece integral construction. ### Claim 9 (depends on 8) The device according to claim 8, wherein the channel is non-radial relative to the longitudinal axis. ### Claim 10 (depends on 8) The device according to claim 8, wherein the channel is non-axial relative to the longitudinal axis. ### Claim 11 (depends on 8) The device according to claim 8, wherein the channel is non-radial and non-axial relative to the longitudinal axis. ### Claim 12 (depends on 8) The device according to claim 8, wherein the spray head, including the spray orifice and the spray profile with the central pin are molded as a one-piece integral construction. ### Claim 13 (depends on 8) The device according to claim 8, wherein the spray head, including the spray orifice and the spray profile with the central pin are molded as a one-piece integral construction from the same material. ### Claim 14 (depends on 8) The device according to claim 8, wherein the spray head is assembled directly on the syringe by inserting a portion of the syringe into the hollow body.
