The invention concerns a nozzle for spraying a product, comprising a cylindro-conical body (10) having an axial channel (12) delimited at its upper end by a transverse wall (18) having a spraying orifice (20). An axial core (24) is arranged in the channel (12) and its upper end (24A) is located opposite the transverse wall (18) for delimiting therewith a spraying chamber (21). A communication between the lower end (12B) of the channel and the spraying chamber is provided between the core and the channel wall, whereof the lower end is capable of communication with a reservoir containing the product to be sprayed. The core (24) includes means forming a catching flange (26) having a catching edge (28) facing the lower end of the core and co-operating with the channel wall (13) to maintain the core in said channel.
An end piece for spraying a product, comprising a cylindroconical body having an axial channel whose first end is delimited by a transverse wall exhibiting a spray orifice and whose second end is capable of communicating with a reservoir, the end piece further comprising an axial core disposed in the channel, whose first end is situated facing said transverse wall and defines with the latter a spray chamber and whose second end is situated in the vicinity of the second end of the channel, a communicating passage between said second end and the spray chamber being formed between the core and the wall of the channel,
