Abstract:
A fluid dispenser having a fluid reservoir, a fluid suction chamber of variable volume that defines an extraction and application space; a dip tube that connects the reservoir to the chamber at an injection orifice that defines an injection axis; and a suction mechanism for sucking, during a suction stage, fluid from the reservoir into the chamber through the injection orifice. The injection orifice is situated a little way inside or outside the extraction and application space, such that the fluid is injected in the form of an axial jet into the extraction and application space and fills it, at least in part, without the injection orifice penetrating into the space.

Abstract:
A fastener device for fastening a dispenser member on a neck of a reservoir, the device including a fastener ring. The fastener ring having reception mechanism for receiving, in stationary manner, the dispenser member; an annular plate for exerting axial pressure on the neck; and a fastener skirt that extends downwards from the plate, the skirt including a fastener mechanism for fastening around the neck. The ring is made of two different plastics materials, a substantially-hard first material and a flexible second material that is more flexible than the first material. The device also includes a hoop that, in the final assembled position, extends around the skirt of the ring with radial clamping. The flexible second material comes into contact with the hoop.
Abstract:
A fluid dispenser including a reservoir forming a neck presenting a thread, a dispenser member, and a fastener system including a fastener ring provided with assembly means for assembling on the thread of the neck in such a manner that the ring is unscrewable from the neck over an axial unscrewing stroke. The outer wall of the neck is provided with a shoulder, and the fastener system includes a security band engaged on the fastener ring. The band axially abuts the shoulder and is secured to the fastener ring at the end of the unscrewing stroke, so as to prevent the fastener system from being removed from the neck immediately after the fastener ring has been unscrewed. The security band includes an unblocking mechanism for disengaging the band from its axial abutment with the shoulder of the neck.
Abstract:
The invention concerns a fluid product dispensing head designed to be mounted on a fluid product dispensing member, said head comprising: a body (1) defining a dispensing channel (13) having a substantially axial inlet (131), open downwards and designed to be connected to the dispensing member, and a lateral outlet (132) emerging onto an outer peripheral surface (15) of the body; and an outer ring (2) defining a dispensing orifice (23), the body being mounted in the ring such that the lateral outlet (132) of the channel (13) communicates with the dispensing orifice (23). The invention is characterized in that the ring (2) comprises stop means (26, 27), the body defining a support surface (17) in abutting contact with the stop means, the body being insertible from the top into the ring.
Abstract:
A fluid dispenser device, comprising: a chamber (15, 15′) provided with an inlet valve (2, 112) and with an outlet valve (67, 76), and defining a sealed slide cylinder (14); a piston (6) disposed inside the chamber and including a lip (61) capable of sliding in sealed manner in said slide cylinder (14); a bearing flange (42) for coming to bear against a reservoir neck; and a ferrule (5) against which the piston (6) is resiliently urged in the rest position; said device being characterized in that the sealed slide cylinder (14) is situated above the bearing flange (42), so that it cannot be inserted into a reservoir neck.
Abstract:
A fluid dispenser comprising: a fluid reservoir (1) provided with a neck (11) that is externally threaded and that internally defines an opening (10) that communicates with the inside of the reservoir, the neck (11) forming at least one helical thread (12); a dispenser head (2) mounted on the neck (11) of the reservoir (1), the head (2) comprising: a dispenser member (3), such as a pump or a valve; a pusher (4) for actuating the dispenser member (3); and a fastener member (5, 6) engaged both with the threaded neck (11) of the reservoir (1) and with the dispenser member; the fluid dispenser being characterized in that the fastener member (5, 6) comprises: a deformable and malleable skirt (51) for coming into engagement with the threaded neck (11); and a rigid hoop (6) that is engaged around the skirt (51) so as to push the skirt radially against the threaded neck (11) in such a manner as to deform the skirt (51) against the thread (12) so as to create a thread imprint (530) in the skirt.
