Abstract: A dosing nozzle is intended to be fitted onto a container containing a product. The nozzle comprises a dosing cavity which can move between a first position and a second position in which it occupies a minimum volume, the cavity being delimited by first and second pistons capable of sliding inside a fixed body. The first piston is fixed to a closure member capable, selectively, of closing off/exposing at least one outlet of the dosing cavity. During a first phase of the movement of the dosing cavity, the first piston is driven by through the effect of the pressure of the product being exerted on the second piston and, during a second phase of the movement of the dosing cavity, the first piston is driven by the pressure of the product being exerted on the first piston, the second piston being immobilized in translation during this second phase.

Abstract: A dispenser for dispensing a product. The dispenser comprises a container for containing a product. The container comprising a body having at least one deformable wall and an opening. The dispenser also comprises a dispensing adapter on the container. The dispensing adapter has a flow passage to be placed in flow communication with the opening of the container, and an outlet orifice forming a seat. A closure is configured to be received in a sealed position on the seat. A mount connects the closure to the dispensing adapter. At least a portion of the mount is elastically deformable and is configured such that force applied to the closure moves the closure away from the seat so as to allow the product to flow through the outlet orifice, and the closure elastically returns to the sealed position on the seat when the force is removed.

Abstract: A dispenser comprises a reservoir containing a pressurized product and the reservoir has an opening in which a valve is mounted. The valve comprises an closure element disposed within the reservoir. In response to an actuation of the dispenser, the closure element moves to an open position and allows the product to be dispensed under pressure from the reservoir through at least one outlet of the dispenser. When actuation of the dispenser ceases, the closure element returns to a closed position preventing flow communication between the outlet and the reservoir. The closure element moves to the closed position substantially by the pressure inside the reservoir acting on the closure element. The closure element is integral with a valve stem of the valve.
