Disclosed is a refillable fluid product dispenser comprising:

Fluid product dispenser

A fluid product dispenser having a vessel and provided with a neck forming at least one helical thread, and a dispensing head mounted on the neck of the vessel, the head having a dispensing member and a fastening member engaging both with the threaded neck and the dispensing member The fastening member has a deformable and malleable skirt intended to engage with the threaded neck, and a rigid collar engaged around the skirt to push the skirt radially against the threaded neck in such a way as to deform the skirt against the thread so as to create a thread imprint in the skirt. The helical thread has an intermediate portion that has, on at least some of its length, a cross-section that decreases in the unscrewing direction and increases in the screwing direction, such that the unscrewing torque decreases and the rescrewing torque increases.

A fluid dispenser member, such as a pump, having a body () for mounting in the opening of a fluid reservoir so as to take fluid therefrom. The body () has a fluid chamber () that defines a fluid inlet in the form of a socket (). The dispenser member includes a dip tube () for extending into the fluid reservoir so as to take fluid therefrom, the dispenser member further having a reducer sleeve () that internally receives an end () of the dip tube (), and that is engaged axially in the socket () of the body (), such that fluid communication is established between the dip tube () and the chamber () of the body (). The dip tube () presents an outside diameter less than 1 mm and is made of a material that is transparent or translucent.

Fluid dispenser member with transparent or translucent dip tube

A fluid dispenser including a fluid reservoir containing fluid; a fluid suction chamber of variable volume including an extraction and application space that varies between a minimum volume and a maximum volume; a dip tube that connects the reservoir to the suction chamber at an orifice; a suction mechanism for sucking, during a suction stage, fluid from the reservoir into the chamber through the orifice; and an extractor and applicator member that defines, in part, the suction chamber and the suction mechanism, and further the extraction and application space; wherein the sliding of the slidable sleeve over the stationary stem does not involve any resilient driving force.

Fluid dispenser

A fluid dispenser member for mounting on an opening () of a fluid reservoir (), said member comprising: a body () inwardly defining a chamber () of variable volume, said body defining a bottom end (); an actuator rod () that can be reciprocated axially in said body, and comprising a top portion defining a top end (); a peripheral bearing collar () extending radially outwards, and including a bottom face () designed to come into abutment, at least indirectly, against an edge () of the opening () of the fluid reservoir; and a neck gasket () disposed in contact with the bottom face () of the collar so as to be compressed between the collar () and the edge () of the opening, the axial height HSaxially separating the bottom face of the collar from the top end of the actuator rod being substantially equal to the axial height HIaxially separating the bottom face of the collar from the bottom end of the body.

Fluid product dispensing element and dispenser comprising one such element

A fluid dispenser member comprising a body (), an actuator element (), and a return spring (), said actuator element comprising a portion disposed inside the body and a top portion () that projects out from the body, said actuator element being axially displaceable, downwards and upwards, inside said body between a rest position and a depressed position, said actuator element being urged towards the rest position by the return spring (), the dispenser member being characterized in that it further comprises blocking means () for preventing the actuator element () from turning relative to said body ().

Fluid dispenser member

A fluid dispenser device includes a chamber provided with an inlet valve and with an outlet valve, and defining a sealed slide cylinder; a piston disposed inside the chamber and including a lip capable of sliding in sealed manner in the slide cylinder. A bearing flange for coming to bear against a reservoir neck; and a ferrule against which the piston is resiliently urged in the rest position. The device being characterized in that the sealed slide cylinder is situated above the bearing flange so that it cannot be inserted into the reservoir neck.
