Abstract:
A fastener device (1) for fastening a fluid dispenser member (2) on a reservoir neck (3) having an inner wall (31) and a top end-wall (32), said fastener device including receiver means (10) adapted to receive a dispenser member (2) in secure manner, and fastener means (14, 15) capable of becoming engaged with the reservoir neck (3), the fastener means including an adhesive-coated application zone (14) capable of coming into contact with the reservoir neck (3), said device being characterized in that the adhesive-coated application zone (14) is designed to come into contact with the top end-wall (32) of the neck (3).
Abstract:
A fluid dispenser member for mounting on an opening (90) of a fluid reservoir (9), said member comprising: a body (1) inwardly defining a chamber (15) of variable volume, said body defining a bottom end (10); an actuator rod (7) that can be reciprocated axially in said body, and comprising a top portion defining a top end (79); a peripheral bearing collar (52) extending radially outwards, and including a bottom face (51) designed to come into abutment, at least indirectly, against an edge (911) of the opening (90) of the fluid reservoir; and a neck gasket (2) disposed in contact with the bottom face (51) of the collar so as to be compressed between the collar (52) and the edge (911) of the opening, the axial height HS1 axially separating the bottom face of the collar from the top end of the actuator rod being substantially equal to the axial height HI1 axially separating the bottom face of the collar from the bottom end of the body.
