Definitions
- the present invention relates to a fluid dispenser device intended to be associated with a fluid reservoir to thereby form a fluid dispenser.
- the dispenser is often referred to as a "vaporizer".
- the preferred field of application of the present invention is that of perfumery or cosmetics, but can of course be applied to other areas where a distribution of fluid product is necessary.
- the dispensing device of the invention is of a particular type ensuring a mixed or bi-phasic distribution of the fluid product with a propellant gas, conventionally air.
- the dispensing device thus generally comprises a fluid dispensing orifice through which the mixture of fluid and air is dispensed in pulverized form.
- the device also comprises a pressurized air duct having a downstream end opening near the dispensing orifice, and an air flush, such as a collapsible soft bulb, connected to an upstream end of the air duct. for supplying a flow of pressurized air through the air duct to the dispensing orifice.
- the device also comprises a fluid product channel which connects to the air duct near or at its downstream end, the fluid product in the channel being sucked by the flow of air under pressure by Venturi effect, so as to distribute a mixture of air and fluid through the dispensing orifice.
- This type of dispensing device is often referred to as a "pear pump", which comes from the use of a flush of air in the form of a crushable soft pear.
- This type of dispensing device has been known for a long time, and today gives a classic or retro effect to the fluid dispenser. The use of such a dispenser is done by holding the tank with one hand and crushing the pear with the other hand.
- the dispensing orifice is integral with the reservoir, so that it is the hand that holds the reservoir which directs the dispensing orifice and thus the jet of sprayed product.
- the mixture of air and fluid product is carried out near the dispensing orifice or somewhat upstream of it.
- By crushing the soft bulb air is forced under pressure through the air duct towards the dispensing orifice.
- This air flow has the effect of creating a vacuum inside the fluid channel which is generally connected to the tank by a dip tube. Consequently, the fluid product present in the fluid product channel is sucked by the flow of pressurized air by a well-known Venturi effect phenomenon.
- the fluid product from the channel is introduced into the air flow leaving the air duct.
- the fluid product mixes with the air flow and the mixture thus obtained is expelled through the dispensing orifice in the form of fine droplets of fluid product.
- the actuation of the flush can thus be divided into two phases, namely an elastic crushing phase and an elastic expansion phase.
- the crushing phase the effective volume of the flush is reduced, so that the air contained therein is pressurized and discharged through an opening to the air duct.
- the relaxation phase the effective volume of the hunt increases under the effect of the elastic memory of the hunt, and outside air must therefore penetrate inside the hunt.
- the air flush comprises an end at which the opening connected to the air duct is formed and another opposite end at which an air inlet flap is provided which is open during the phases.
- resilient and closed relaxation during the phases of elastic crushing. Therefore, a conventional hunt includes two separate and separate openings, which complicates on the one hand the manufacture and assembly of the air flush and night on the other hand to its overall aesthetic appearance.
- the object of the present invention is to overcome this aforementioned disadvantage of the prior art by defining a fluid dispenser device of the "pear pump” type, the flushing of which is simpler to manufacture and has a better aesthetic appearance.
- the present invention proposes a fluid product dispensing device intended to be associated with a fluid reservoir to form a fluid dispenser, the device comprising:
- a fluid product dispensing orifice a pressurized air duct comprising a downstream end opening near the orifice and an upstream end;
- a flush of air such as a flexible pear, capable of undergoing phases of crushing and elastic expansion, the flushing of air being connected to the upstream end of the air duct to feed a flow of air under pressure through the air duct to the orifice during the phases of elastic crushing,
- a fluid product duct connecting to the air duct near its downstream end, the fluid product in the duct being sucked by the flow of air under pressure by Venturi effect, so as to dispense a mixture of air and fluid product through the dispensing orifice, characterized in that the flush has only one opening provided with a coupling sleeve defining at least a portion of the air duct, the sleeve comprising in addition to a passage of air entering provided with an air inlet valve able to let outside air into the flush of air during the phases of elastic relaxation and to prevent the exit of air from the flush of air through this passage during the phases of elastic crushing.
- the air inlet valve has been moved from one end of the air flush to the other end where the opening provided with the coupling sleeve is formed.
- An opening has been removed at the level of the flush which then includes only one. It is thus possible to perform air evacuation with the most diverse forms, since it is no longer necessary to provide a specific opening for the air inlet valve.
- the air inlet valve can cooperate with a valve seat so as to rest on its seat during the elastic crushing phases, the air inlet valve being arranged so as to be stressed. on its seat by the flow of air under pressure generated during the phases of elastic crushing.
- the air inlet valve is disposed at the center of the opening and the air flow under pressure that flows to the air duct is directed to the air inlet valve, the flow of pressurized air then passing around the valve.
- the air inlet valve is disposed around the flow of air under pressure. In one way or another, it is ensured that the air inlet valve is pressed in a sealed manner on its seat during the phases of elastic crushing.
- the coupling sleeve may also comprise a non-return valve preventing a suction of fluid product through the air duct into the flush during elastic expansion phases.
- the non-return valve cooperates with a valve seat so as to rest on its seat during elastic expansion phases.
- the check valve comprises a self-sealing slot which opens under the pressure of the air flow generated during the elastic crushing phases and which closes tightly during the elastic expansion phases.
- the air inlet valve and the non-return valve are integral with each other in displacement.
