ABSTRACT:
A device for packaging and dispensing a sterile liquid product. The device comprises a reservoir on which a nozzle is mounted. The nozzle is provided with an inner conduit which has an upstream end communicating with the reservoir and a downstream end opening to the outside via an evacuation orifice. The inner conduit is at last partially obturated by an insert of selective porosity which allows both a metered flow of the product to the outside and a filtration of air sucked towards the inside, stopping biological polluting and/or contaminating agents.
