Abstract: A fluid dispenser device includes a dispenser member, such as a pump or a valve, having an actuator rod. A pusher is mounted to turn on and about the actuator rod and is provided with a dispenser orifice. The dispenser is actuated by applying pressure to the pusher. A fastening ring is provided for fastening the dispenser member on a receptacle. The ring has a fastening system for co-operating with a neck of the receptacle. The fastening ring includes at least one internal locking profile, and the pusher includes at least one locking member which can be engaged with the internal profile to prevent the pusher being actuated. The pusher has at least one inner bushing which includes the locking member. The pusher also has an outer skirt concentric with the inner bushing. The inner bushing defines the dispenser orifice. At least a portion of the inner bushing is received in the fastening ring. The pusher skirt is adapted to surround at least a portion of the fastening ring.

Abstract: A fluid-dispensing member is designed to be mounted on the neck of a container. The dispensing member includes: a body defining a chamber that slidably receives a piston; a fixing member designed to co-operate with the neck and extending around the body; and a delivery channel connecting the chamber to a stationary dispensing orifice. The delivery channel is formed between the body and the fixing member. The fixing member is suitable for co-operating with an inside wall of the neck so as to fix the dispensing member in the neck.
