Abstract: A refillable fluid product dispenser having a fluid product reservoir defining a neck and a filling port; a dispensing member, such as a pump, mounted on the neck of the fluid product reservoir for extracting the fluid product; a filling valve; a chamber separating the filling port from the filling valve. The chamber has a retention mechansim for retaining the fluid product inside the chamber.

Abstract: A fastener ring for fastening a dispenser member, such as a pump or a valve, on a neck of a reservoir, the ring including a reception mechanism suitable for receiving the dispenser member, and a substantially-cylindrical attachment skirt for coming into engagement around the neck of the reservoir. The skirt defining an inner wall that defines a top first inner wall section for coming into engagement with the neck, and a bottom second inner wall section for extending out of contact with the neck. The attachment skirt includes an orientation tab that interrupts the bottom second inner wall section and that projects radially inwards relative to the second section.

Abstract: A fluid dispenser head for associating with a fluid dispenser member (5), such as a pump or a valve, the head comprising an outlet nozzle (1, 2) via which the fluid is dispensed out from the head, the nozzle including an elastically-deformable part (1) that, in use, forms a fluid dispenser orifice in the form of a self-sealing slot comprising two edges that are in mutual leaktight contact in the absence of fluid under pressure in the nozzle, the dispenser head being characterized in that the dispenser orifice does not exist before the head is used for the first time, the orifice being created by the fluid under pressure while the head is being used for the first time, or by the user.

Abstract: A fastener member (1) for fastening a dispenser member (4) on a fluid reservoir, the fastener member (1) having a fastener ring (2) and a covering hoop (3). The fastener ring (2) includes a reception device that receives the dispenser member (4), and a fastener device that fastens on the reservoir, the covering hoop (3) being mounted by axial engagement around the ring (2) in such a manner as to mask it at least in part. The hoop (3) includes a hook co-operating with a retention device (225) formed by the ring (2), the hook (35) prevents the hoop (3) from rotating around the ring (2) and preventing the hoop (3) from moving in axial translation. The retention device formed by the ring (2) includes a retention housing (225) that co-operates with the hook. The hook includes at least one barb profile (352) adapted to bite into the housing.

Abstract: A fluid dispenser device (1) for associating with a fluid reservoir (3), the device including at least one check valve (12, 2) that is suitable for controlling the flow of fluid through the device, the check valve comprising a seat (12), and a movable valve member (2) that defines a contact zone that is suitable for bearing against the seat (12) in leaktight manner, the device including resilient prestress means (23) that urge the valve member in leaktight contact against its seat (12) at rest, the device being characterized in that the prestress means (23) are formed integrally with the valve member.

Abstract: A fastener member (1) for fastening a dispenser member (4), such as a pump or a valve, on a fluid reservoir, said fastener member (1) comprising a fastener ring (2) and a covering hoop (3), the fastener ring (2) including reception means (24) for receiving the dispenser member (4), and fastener means (211) for fastening on the reservoir, the covering hoop (3) being mounted by axial engagement around the ring (2) in such a manner as to mask it at least in part, the hoop (3) including hook means (35) co-operating with retention means (225) formed by the ring (2), said hook means (35) include means (351, 352) for preventing the hoop (3) from rotating around the ring (2) and means (352) for preventing the hoop (3) from moving in axial translation, and thereby becoming axially disengaged from the ring (2), the retention means formed by the ring (2) including at least one retention housing (225) that is accessible by axial engagement, said means for preventing both turning and movement in translation co-operating w
