Abstract

Head for spraying a product in a spraying direction, for example a cosmetic product, in particular a deodorant, this spray head comprising: a body, comprising: a channel for conveying the product, a housing in which the conveying channel emerges, the spray head also comprising: a spray nozzle mounted on the housing, this nozzle comprising at least two, better still three, spray orifices, respective feed channels being formed between the nozzle and the body, these channels connecting the conveying channel to the said corresponding spray orifices, and being obliquely inclined relative to the spraying direction.

First claim

The invention claimed is:

1. A head for spraying a product in a spraying direction, the spray head comprising:
a body comprising:
a channel for conveying the product, and
a housing in which the conveying channel emerges; and

a spray nozzle mounted on the housing, the spray nozzle comprising at least two spray orifices, the spray orifices being defined within the spray nozzle itself,
wherein respective feed channels are formed between the spray nozzle and the body, the feed channels connecting the conveying channel to the corresponding spray orifices, and being obliquely inclined relative to the spraying direction, and
wherein the spray orifices are positioned at 120° with respect to one another, around an axis of the spray nozzle.

2. The spray head according to claim 1 , the spray nozzle being deprived of a central channel.

3. The spray head according to claim 2 , wherein the feed channels extend along respective longitudinal axes which are obliquely inclined with respect to the spraying direction by an angle of between 30° and 60°.

4. The spray head according to claim 1 , wherein an angle of a longitudinal axes of the feed channels relative to the spraying direction is the same for each of the feed channels.

5. The spray head according to claim 1 , wherein the nozzle comprises recesses which partially define the feed channels.

6. The spray head according to claim 1 , wherein the spray orifices have axes which are parallel to one another and are parallel to the spraying direction, which coincides with an axis of the spray nozzle.

7. The spray head according to claim 1 , wherein the spray nozzle comprises a peripheral fitting skirt provided with one or more raised parts used for snapping onto the body of the spray head.

8. The spray head according to claim 1 , wherein the spray nozzle exhibits a front face on which the spray orifices emerge, the front face being a face which is fully visible when the spray nozzle is fitted to the body of the dispensing head.

9. The spray head according to claim 8 , wherein the front face exhibits a central cutout, around which the spray orifices are positioned.

10. The spray head according to claim 9 , wherein the central cutout exhibits a conical bottom.

11. The spray head according to claim 1 , wherein the spray orifices terminate in a narrowing of their section.

12. The spray head as claimed in claim 1 , wherein the body of the spray head is one-piece and is produced with at least one raised part intended to fix the spray head to a container.

13. The spray head according to claim 12 , wherein the conveying channel is produced with a push button, which is connected via a flexible portion to a fitting hoop on the container.

14. The spray head according to claim 1 , wherein the spray nozzle is fixed in the housing without prior location of its orientation around its axis.

15. A method for the cosmetic treatment of human keratinous substances, comprising a stage of spraying at least one cosmetic product over the keratinous substances, the spraying being carried out using a spray head as defined in claim 1 .

16. The method according to claim 15 , wherein the cosmetic product is chosen from body hygiene products, deodorant or antiperspirant products, styling products, or colouring products.

17. The method according to claim 16 , wherein the cosmetic product is a deodorant product.

18. The method according to claim 15 , wherein the spray head makes it possible to obtain, when the product is sprayed over a target 15 cm away from the spray head and perpendicular to an axis of spraying:
at least 50% of a weight of product sprayed which reaches a disc of the target centred on the axis of spraying and with a radius of 2 cm.

19. The method according to claim 15 , wherein the product is sprayed over the skin.

20. The method according to claim 15 , the product being sprayed over the keratinous fibres, preferably the hair.

21. A use of a spray head according to claim 1 for spraying a cosmetic product over keratinous substances, in order to improve accuracy of the spraying of the cosmetic product and/or a concentration of the cosmetic product close to an axis of the spraying, the spraying being configured such that, when the product is projected onto a target 15 cm away from the spray head and perpendicular to the axis of spraying:
at least 50% of a weight of product sprayed reaches a disc of the target centered on the axis of spraying and with a radius of 2 cm.

22. A cosmetic kit comprising, with one and the same packaging:
a spray head according to claim 1 ; and
a cosmetic product chosen from body hygiene products, deodorant or antiperspirant products, styling products, or colouring products.

23. The kit according to claim 22 , further comprising a container configured to contain the cosmetic product and on which the dispensing head is configured to be positioned and fixed.

24. A head for spraying a product in a spraying direction, the spray head comprising:
a body comprising:
a channel for conveying the product, and
a housing in which the conveying channel emerges; and

a spray nozzle mounted on the housing, the spray nozzle comprising at least two spray orifices,
wherein respective feed channels are formed between the spray nozzle and the body, the feed channels connecting the conveying channel to the corresponding spray orifices, and being obliquely inclined relative to the spraying direction, and
wherein the spray orifices emerge on respective bosses projecting from a front face of the spray nozzle.
