Device for dispensing a fluid product

Device for dispensing a fluid product comprising a reservoir (10) which is suitable for containing at least one dose of fluid product and one dispensing head (20) attached to said reservoir (10), said dispensing head (20) comprising a cannula (21) provided with a dispensing opening (22) and defining an expulsion channel (24), wherein said dispensing opening (22) comprises a spray tip (25) which is partially inserted into said expulsion channel (24), said spray tip (25) comprising a head part (26) arranged outside of said cannula (21) and a rod part (28) inserted into said expulsion channel (24), said head part (26) extending the rod part (28) and comprising a diameter which is greater than the diameter of said rod part (28) to define an impact surface (27) downstream of said dispensing opening (22), such that during actuation, said fluid product flowing under pressure in said expulsion channel (24) strikes said impact surface (27) in order to generate a spray, wherein the diameter of said rod part (28) is less than the diameter of said expulsion channel (24), said rod part (28) being centred in said expulsion channel (24), said rod part (28) being attached in said expulsion channel (24) by clamping at one or more deformation points (29) made on said cannula (21), the maximum external diameter of said head part (26) being similar, in particular identical, to the external diameter of said cannula (21), so that the spray tip (25) does not increase the external diameter of the cannula (21).
