1. A container comprising: at least one cosmetic product to be dispensed contained in the container;at least one hollow valve rod or hollow pump rod; anda dispensing head, the dispensing head comprising: a body; andan engaging part that defines with the body, at rest, a dispensing orifice having an annular section, the dispensing orifice being formed between the engaging part and the body such that the dispensing orifice is already open when the cosmetic product is sent into the dispensing head to be dispensed,wherein the dispensing head is configured to be pressed to activate the hollow valve rod or hollow pump rod to convey the at least one cosmetic product through the dispensing orifice of the dispensing head from the container. 2. The container according to claim 1, wherein the dispensing head further comprises an opening passing axially through the engaging part. 3. The container according to claim 1, wherein the dispensing head further comprises a distribution chamber being formed upstream of the dispensing orifice between the engaging part and the body, wherein a supply duct for the product opens onto said distribution chamber. 4. The container according to claim 1, wherein the width of the space between the engaging part and the body decreases towards the dispensing orifice. 5. The container according to claim 1, wherein the width of the space between the engaging part and the body increases towards the dispensing orifice. 6. The container according to claim 1, wherein the dispensing head further comprises surfaces parallel to a dispensing axis, wherein the parallel surfaces define a passage that opens onto the dispensing orifice. 7. The container according to claim 1, wherein the dispensing orifice has a constant width in a circumferential direction. 8. The container according to claim 1, wherein the dispensing orifice has axial symmetry, preferably rotational symmetry. 9. The container according to claim 1, wherein the engaging part is hollow and provided with an internal recess, the internal recess communicating with a space formed between the engaging part and a housing of the body, the product reaching said dispensing orifice through said space. 10. The container according to claim 9, said body comprising a supply duct, the supply duct opening out next to the internal recess in the engaging part, the product to be sprayed reaching the engaging part through the supply duct. 11. The container according to claim 1, wherein at least one of the body and the engaging part has at least one relief for centering the engaging part in a housing in the body. 12. The container according to claim 1, wherein the engaging part comprises a foot fixed to the body, the foot extending on a side of the engaging part located opposite to the dispensing orifice, the cosmetic product being supplied into a space formed between the engaging part and the body, a supply duct opening into said space at a location between two opposite axial ends of the engaging part. 13. The container according to claim 1, wherein the dispensing head further comprises two housings and two engaging parts disposed in the housings, each engaging part defining with the body, at rest, a dispensing orifice having an annular section. 14. The container according to claim 1, wherein an inlet of the product into a space defined between the engaging part and the body takes place through a supply duct having a cross-section greater than that of the dispensing orifice. 15. The container according to claim 1, wherein the dispensing orifice has, in an axial sectioning half plane, an axis, the axis converging in relation to a spraying direction. 16. The container according to claim 1, wherein the dispensing orifice has, in an axial sectioning half plane, an axis, the axis diverging in relation to a spraying direction. 17. The container according to claim 1, wherein the engaging part lies flush with a front end of the body. 18. The container according to claim 1, wherein the engaging part extends axially beyond a front end of the body. 19. The container according to claim 1, wherein the engaging part extends axially beyond a front end of the body. 20. The container according to claim 1, wherein the container is pressurized. 21. A container comprising: at least one cosmetic product to be dispensed contained in the container;at least one hollow valve rod or hollow pump rod; anda dispensing head, the dispensing head comprising: a body; andan engaging part that defines with the body, at rest, a dispensing orifice having a section, wherein an opening passes axially through the engaging part, the opening being configured to allow air to flow through the engaging part to the dispensing head under an entrainment effect of a spray emitted through the dispensing orifice.wherein the dispensing head configured to be pressed to activate the hollow valve rod or hollow pump rod to convey the at least one cosmetic product through the dispensing orifice of the dispensing head from the container. 22. The container according to claim 21, wherein the container is pressurized.
