Abstract: A fluid dispenser head including an inlet well (14), an axial assembly housing (2) in which there extends a pin (3), and a nozzle (4) assembled along an axis X in the axial assembly housing (2). The head also includes two feed ducts (15), each connecting the inlet well (14) to the axial assembly housing (2). The pin forms two swirl channels (35) connected in tangential manner to a swirl chamber (36). The nozzle is in sealing contact with the pin (3) so as to define two connection sections, each connecting a feed duct (15) to a swirl channel (35).

Abstract: A fastener device (1, 2) for fastening a dispenser member (4) on a reservoir neck (51), the device comprising: a ring (1) forming an annular bearing collar (10) for coming to bear against the top (52) of the neck (51), with a gasket (3) possibly being interposed therebetween, and a skirt (11) including a free bottom end (145) and a deformable fastener section (13) that is deformed by thrust on the free end; and a hoop (2) that surrounds the skirt (11) of the ring (1) and constrains the fastener section (13) to deform inwards into contact with the neck (51); the device being characterized in that the deformable fastener section (13) is separated from the free end (145) by a substantially non-deformable bottom section (14) that is in engagement with the hoop (2).

Abstract: A fluid dispenser having a fluid reservoir (2) for containing fluid, the reservoir including an opening (230) having an outer top edge (25) and an inner bottom edge (26); a dispenser member (3), such as a pump or a valve; a fastener that fastens the dispenser member in the opening (230). The dispenser includes a tamperproofing mechanism (1) that is distinct from the fastener and that is secured to the dispenser member (3). The tamperproofing mechanism comes into contact with the inner edge (26) in the event of an attempt at removing the dispenser member (3) from the opening (230).

Abstract: A fastener device for fastening a dispenser member (4) on a neck (11) of a fluid reservoir (1), the device including: a fastener ring (2) including a reception mechanism (21) and a fastener mechanism (23) for engaging around the neck (11) of the reservoir (1); and a blocking hoop (3) engaged around the ring (2) and movable relative to the ring between a provisional pre-assembled position and a final assembled position. The hoop (3) includes a clearance section (32) that, in the provisional position, is disposed around the fastener mechanism (23), but with an intermediate clearance gap (E), so as to enable the fastener mechanism (23) to move radially outwards without being hindered by the hoop (3), and is offset axially in the final position relative to the fastener mechanism (23), so as to enable the hoop to block the ring (2) on the neck (11).
