Abstract: A refillable fluid dispenser comprising a fluid reservoir (1), a dispenser member (3), such as a pump, and a filler valve (2) for filling the fluid reservoir (1) once it is empty of fluid and full of air, the dispenser being characterized in that it further comprises air exhaust means (5, 6) for extracting the air from the fluid reservoir (1), and for creating therein suction for sucking the fluid through the filler valve (2) in its open state.

Abstract: A fluid dispenser head, such as a pusher, includes an inlet duct, and a dispenser orifice in dispensing communication with the inlet duct. The dispenser head further includes diversion means for selectively interrupting dispensing communication between the inlet duct and the dispenser orifice, and for establishing filling communication with a filling duct formed by the dispenser head and exiting outside the dispenser head.

Abstract: A fluid dispenser comprising: a flexible pouch (1) that comprises two flexible sheets (11, 12) that define between them a fluid reservoir (10) and an opening (14); and a stopper-and-dispenser member (2) that is mounted in stationary, permanent, and leaktight manner in the opening (14) of the pouch (1), the stopper member (2) including a body (3) that defines a dispenser orifice (34) and two sealing zones (31c, 31d), respectively for the two flexible sheets (11, 12) of the pouch (1); the dispenser being characterized in that the stopper-and-dispenser member (2) further includes a closure lid (4) for closing the dispenser orifice (34), the lid (4) being hinged (43) on the body (3) in such a manner as to pivot between a closed position and an open position.

Abstract: A fluid-flow control valve includes an inlet (E) for connecting to a feed duct; an outlet (S) for connecting to an evacuation duct; a valve member (1) that, at rest, bears against a valve seat (2) to isolate the inlet (E) from the outlet (S); and an actuator mechanism (5, C) for moving the valve member (1). The actuator mechanism includes a chamber (C), which communicates with the inlet (E) via a hole (11) and is disposed relative to the valve member (1) on its side facing away from the seat (2), in such a manner as to urge the valve member against its seat; and a bypass (5) that connects the chamber (C) to the outlet (S), the bypass being controllable between an open state for passing fluid, and a closed state.

Abstract: The invention concerns a device for dispensing a fluid product designed for being screwed on a threaded neck of a fluid product reservoir, the device including a threaded fixing element for being in threaded engagement with the threaded neck of the reservoir for fixing the dispensing device on the reservoir neck. The invention is characterized in that a unidirectional driving member is provided covering the fixing element so as to prevent any access to the fixing element when it is screwed on the reservoir neck, such that the fixing element cannot be unscrewed by rotation of the unidirectional driving member.

Abstract: A finger-operable pump includes a pump body, a non-return valve, and an actuating plunger. A plunger return spring biases the plunger toward an elevated, rest position. A piston is carried by the plunger and is movable relative to the plunger between a closed position sealing a discharge passage in the plunger and an open position in which fluid can flow from the pump through the plunger discharge passage and out of the pump. A piston return spring is provided between the piston and the plunger for biasing the piston toward the closed position, and the piston return spring includes a post which is resiliently bendable.
