Abstract:
1. A fluid dispenser device for associating with a fluid reservoir so as to form a fluid dispenser, the device comprising: a fluid dispenser orifice; an air duct for air under pressure, said air duct including an upstream end and a downstream end that opens out in the proximity of the orifice; an air expeller that is suitable for being subjected to elastic squeezing and relaxation stages, the air expeller being connected to the upstream end of the air duct so that, during elastic squeezing stages, it delivers a flow of air under pressure through the air duct until it reaches the orifice; a fluid channel that is connected to the air duct in the proximity of its downstream end, the fluid in the channel being sucked up by the flow of air under pressure by the Venturi effect, in such a manner as to dispense a mixture of air and fluid through the dispenser orifice; the air expeller has a single opening that is provided with a connection sleeve that defines at least one portion of the air duct, the sleeve further including an incoming-air passage that is provided with an air-inlet valve that is suitable for allowing outside air to enter into the air expeller during elastic relaxation stages, and for preventing air from leaving the air expeller through the passage during elastic squeezing stages, wherein the air expeller, when in the relaxation stage, has a cross-section that expands in a direction away from the upstream end of the air duct where the expeller is connected so as to define a shape configured to be squeezed between two opposing fingers in order to collapse the expeller; and a check valve interconnected with the air inlet valve by a connection rod, such that the two valves are secured to each other in movement.
