Abstract

Dispensing head (1) intended to be fitted on a container that contains at least one product to be dispensed, this dispensing head comprising:

• • a body (3),
  • an engaging part (10), in particular a core (10), that defines with the body (3), at rest, a dispensing orifice (12) having an annular section.

Claims

1. Dispensing head intended to be fitted on a container that contains at least one cosmetic product to be dispensed, this dispensing head comprising:

a body,

an engaging part that defines with the body, at rest, a dispensing orifice having an annular section.

3. Head according to claim 1, a passage passing axially through the engaging part.

4. Head according to claim 1, a distribution chamber being formed between the part and the body-upstream of the dispensing orifice, a supply duct for the product opening onto said distribution chamber.

5. Head according to claim 1, the width of the space between the part and the body decreasing towards the dispensing orifice.

6. Head according to claim 1, the width of the space between the part and the body increasing towards the dispensing orifice.

7. Head according to claim 1, comprising surfaces parallel to a dispensing axis, defining a passage that opens onto the dispensing orifice.

8. Head according to claim 1, the dispensing orifice having a constant width in a circumferential direction.

9. Head according to claim 1, the dispensing orifice having axial symmetry, preferably rotational symmetry.

10. Head according to claim 1, the part being hollow and provided with an internal recess, the internal recess communicating with a space formed between the part and a housing of the body, the product reaching said dispensing orifice through said space.

11. Head according to claim 10, said body comprising a supply duct, the supply duct opening out next to the internal recess in the part, the product to be sprayed reaching the part through this supply duct.

12. Head according to claim 1, at least one of the body and the part having at least one relief for centring the part in a housing in the body.

13. Head according to claim 1, the part comprising a foot fixed to the body, the foot extending on the side of the part located opposite to the dispensing orifice, the product being supplied into the space formed between the part and the body, a supply duct opening into said space at a location between two opposite axial ends of the part.

14. Head according to claim 1, comprising two housings and two engaging parts disposed in the housings, each defining with the body, at rest, a dispensing orifice having an annular section.

15. Head according to claim 1, an inlet of the product into a space defined between the part and the body taking place through a supply duct having a section greater than that of the dispensing orifice.

16. Head according to claim 1, the dispensing orifice having, in an axial sectioning half plane, an axis, the axis converging in relation to a spraying direction.

17. Head according to claim 1, the dispensing orifice having, in an axial sectioning half plane, an axis, the axis diverging in relation to a spraying direction.

18. Head according to claim 1, the engaging part lying flush with a front end of the body.

19. Head according to claim 1, the engaging part being axially set back from a front end of the body.

20. Head according to claim 1, the engaging part extending axially beyond a front end of the body.

21. Container provided with a dispensing head according to claim 1.

22. Container according to claim 21, the product being a cosmetic product.

23. Container according to claim 21, the container being a pressurized container.

2. Dispensing head intended to be fitted on a container that contains at least one product to be dispensed, this dispensing head comprising:

a body,

an engaging part that defines with the body, at rest, a dispensing orifice having an annular section, a passage passing axially through the engaging part.
