Abstract

The subject of the invention is a device for dispensing a cosmetic composition, comprising a dispensing head ( 1 ) intended to be fitted on a container containing said cosmetic composition to be dispensed,
(i) the dispensing head comprising: a body ( 3 ) that is open at its two opposite axial ends, an engaging part ( 10 ) that is open at its two opposite axial ends and at least partially defines at least one dispensing orifice ( 12 ), the individual cross section of the dispensing orifice being between 0.03 mm 2 and 0.5 mm 2 , and (ii) the cosmetic composition comprising, in a cosmetically acceptable medium, at least one emulsion chosen from a water-in-oil emulsion and an oil-in-water emulsion, at least one cosmetic active agent, in particular at least one deodorant active agent and/or antiperspirant active agent.

First claim

The invention claimed is:

1. A device for dispensing a cosmetic composition, the device comprising a dispensing head comprising:
a base fitted on a container containing the cosmetic composition;
an annular housing disposed on the base and comprising a supply duct configured to guide the cosmetic composition from the container to an inner surface of the housing;
an annular core disposed inside the housing and having an inner surface that defines an opening of the dispensing head; and
axial ribs disposed between the core and the housing, the ribs at least partially defining dispensing orifices configured to divide the cosmetic composition into separate streams and dispense the separate streams from the dispensing head, such that the streams are oriented parallel to a dispensing axis that extends axially through the annular core or converge upon the dispensing axis outside of the opening of the dispensing head,
wherein the individual cross section of each dispensing orifice ranges from 0.01 mm 2 to 0.5 mm 2 , and
wherein the cosmetic composition comprises:
at least one emulsion chosen from a water-in-oil emulsion and an oil-in-water emulsion; and
at least one cosmetic active agent.

2. The device of claim 1 , wherein each dispensing orifice is annular and has a constant width in the circumferential direction.

3. The device of claim 1 , wherein each dispensing orifice exhibits axial symmetry.

4. The device of claim 1 , wherein each dispensing orifice has a triangular cross section.

5. The device of claim 1 , wherein the dispensing orifices vary in size, such that the dispensing orifices are configured to accelerate the streams of the cosmetic composition.

6. The device of claim 5 , wherein the number of dispensing orifices is greater than or equal to 5.

7. The device of claim 5 , wherein the individual cross sections of the dispensing orifices range from 0.03 mm 2 to 0.4 mm 2 .

8. The device of claim 1 , wherein an oily phase of the emulsion comprises at least one hydrocarbon-based oil.

9. The device of claim 1 , wherein an oily phase of the emulsion comprises at least one silicone oil.

10. The device of claim 1 , wherein the cosmetic composition is free of solid particles and fillers.

11. The device of claim 1 , wherein the cosmetic composition is free of perlite.

12. A process for the dispensing of a cosmetic composition comprising:
dispensing a cosmetic composition from a dispensing device, the device comprising a dispensing head comprising:
a base fitted on a container containing the cosmetic composition to be dispensed;
an annular housing disposed on the base and comprising a supply duct configured to guide the cosmetic composition from the container to an inner surface of the housing;
an annular core disposed inside the housing and having an inner surface that defines an opening of the dispensing head; and
axial ribs disposed between the core and the housing, the ribs at least partially defining dispensing orifices configured to divide the cosmetic composition into separate streams and dispense the separate streams from the dispensing head, such that the streams are oriented parallel to a dispensing axis that extends axially through the annular core or converge upon the dispensing axis outside of the opening of the dispensing head,
wherein the individual cross section of each dispensing orifice ranges from 0.01 mm 2 to 0.5 mm 2 , and
wherein the cosmetic composition comprises:
at least one emulsion chosen from a water-in-oil emulsion and an oil-in-water emulsion, and
at least one cosmetic active agent.
