Description

FIELD OF THE INVENTION The present invention relates to the field of devices for emitting active compounds, in particular of the perfume or liquid type with active principle, in atmospheric air.

PRIOR ART Devices for emanating perfumes or liquids with an active principle in atmospheric air, and more particularly perfumes, are well known to those skilled in the art. Such devices are more commonly referred to as the "diffuser tree" or "Fragrance Tree".

Such devices ensure the diffusion of a liquid composition, in particular perfuming and optionally colored, via a material, generally porous, capable of diffusing the composition into the atmosphere (also referred to as "means of transport"). To date, all these devices use homogeneous liquid compositions monophasis s.

In particular for the sake of differentiation and originality, the inventors are interested in the implementation of bi-phasic compositions. This type of compositions confers first of all a new original aesthetic effect and thus seduces the users. However, the implementation of two immiscible phases between them must not alter the diffusion properties of the associated perfume.

The inventors have unexpectedly found that all of these requirements can be satisfied subject to considering a specific bi-phasic medium. SUMMARY OF THE INVENTION According to a first of its aspects, the present invention relates to a device for emanating at least one active compound into atmospheric air, the device comprising: a container provided with at least one opening; a liquid composition contained in the container, and - at least one means of transport, in contact with the composition present in the container, and having a diffusing part in the open air, this transport means being able to diffuse the composition into the atmosphere, said composition comprising at least two distinct phases immiscible with each other, the first phase being a volatile hydrophobic phase and liquid at ambient temperature (25 ° C.) and atmospheric pressure (760 mmHg) and the second phase being a phase hydrophilic volatile and liquid at room temperature (25 ° C) and atmospheric pressure (760 mmHg), at least one of the first and / or second phase (s) further comprising at least one component active ingredient selected from a fragrance, an active ingredient liquid, and mixtures thereof. By "volatile" is meant in the sense of the invention a compound capable of evaporating at least partly at room temperature (25 ° C) and atmospheric pressure (760 mm Hg).

The original aesthetic effect obtained with such a composition is without prejudice to the diffusion in the means of transport and in the ambient atmosphere of the composition contained in the container. A composition according to the invention also makes it possible to control the diffusion profile of the active compound, in particular the perfume.

The coexistence of two phases with different degrees of volatility makes it possible in fact to immediately diffuse the most volatile phase and then to extend the diffusion in duration thanks to the less volatile phase. The lengthening of the duration of diffusion of the compositions also meets an expectation of the users in this sense.

A device according to the invention can therefore even provide diffusion in the atmosphere of at least one active compound, in particular at least one perfume, over a prolonged period compared with conventional devices. As such, the first phase may comprise a perfume, if necessary different from the perfume included in the second phase when the latter is provided, or vice versa.

Thus, such a device according to the invention even allows sequential diffusion of different flavors, and thus leads to different olfactory experiences / atmospheres. According to another of these aspects, the present invention relates to the use of a composition as defined above, for the odorization and / or the treatment of atmospheric air.

DESCRIPTION OF THE FIGURE Figure 1 illustrates a device according to the invention comprising: - a transparent container having an opening and a flow reducer reducing the section of the opening, - a liquid composition contained in the container the composition comprising the two distinct immiscible phases required according to the invention, and rattan wooden rods (or capillates) as transport means.

DETAILED DESCRIPTION OF THE INVENTION The invention relates more particularly to the implementation of a bi-phasic liquid composition. The two phases considered are immiscible with each other and are therefore chosen in view of their lack of affinity for each other.

To satisfy the parallel properties sought in terms of diffusion, the two phases were chosen from a first volatile and liquid hydrophobic phase at ambient temperature (25 ° C.) and atmospheric pressure (760 mmHg) and a second volatile hydrophilic phase. liquid at room temperature (25 ° C) and atmospheric pressure (760 mm Hg), at least one of the first and / or second phase (s) further comprising at least one active compound selected from a perfume, a liquid active ingredient, and mixtures thereof. The second phase according to the invention is that commonly implemented in conventional emanation devices. The originality of the invention lies therefore mainly in the first phase, the nature of which has to be determined so as to satisfy all the above requirements, namely to obtain a bi-phasic composition without altering the diffusion of the active compound in the atmosphere.
