A container of plastic material, having a body extending along a principal axis and a bottom in the extension of the body at a lower end thereof. The bottom has an annular seat defining a seating plane; and a conical arch that extends from near the seat towards the interior of the container to a central apex, the arch having in transverse cross-section a star-shaped profile inscribed between two circles, the ratio of the diameters of which is greater than or equal to 0.7.

1. Container of plastic material, comprising a body extending along a principal axis and a bottom in the extension of the body at a lower end thereof, the bottom comprising: an annular seat defining a seating plane;a conical arch that extends from near the seat towards the interior of the container
1. Container of plastic material, comprising a body extending along a principal axis and a bottom in the extension of the body at a lower end thereof, the bottom comprising: an annular seat defining a seating plane;a conical arch that extends from near the seat towards the interior of the container to a central apex, the conical arch comprises a series of facets,wherein that the arch has in transverse cross-section a star-shaped profile inscribed between an inner circle and an outer circle, the ratio of the diameter of the inner circle to the diameter of the outer circle is greater than or equal to 0.7, the facets, grouped in pairs, defining branches of the star-shaped profile. 2. Container according to claim 1, wherein the ratio of the diameters is between 0.8 and 0.9. 3. Container according to claim 1, wherein angles between the facets of the same branch and between two adjacent facets of two neighboring branches are obtuse in a transverse plane. 4. Container according to claim 3, wherein the angles between facets are greater than or equal to 100°. 5. Container according to claim 1, wherein the arch has two superimposed portions, that are a lower substantially conical portion at an acute angle, which extends from near the seat to an intermediate junction zone, and an upper substantially conical section at an obtuse angle, which extends from the intermediate junction zone to the apex. 6. Container according to claim 5, wherein the lower portion and the upper portion of the arch have axial extensions that are equal or practically equal. 7. Container according to claim 5, wherein the lower portion of the arch has, in axial cross-section, a curved profile with concavity turned towards the axis of the container. 8. Container according to claim 5, wherein the upper portion of the arch has, in axial cross-section, a curved profile with concavity turned opposite to the axis of the container. 9. Container according to claim 7, wherein in axial cross-section, the profiles of the lower portion and the upper portion have respective radii of curvature R1 and R2 such that the ratio R2/R1 falls between 0.6 and 1. 10. Container according to claim 1, wherein the arch has a height measured axially, in that the seat has a width measured transversely, the ratio of the height to the width being greater than 0.25. 11. Container according to claim 1, wherein the conical arch includes an edge near the seat, the edge defining an outer perimeter of the star-shaped profile and lying entirely within the inner circle and the outer circle. 12. Container according to claim 1, wherein each of the facets is planar. 13. A container comprising: a body; anda bottom at a first end of the body, the bottom comprising:an annular seat defining a seating plane;a central apex at the center of the bottom; anda conical arch extending from near the annular seat to the central apex, the conical arch comprises a series of facets,wherein the arch includes in transverse cross-section a star-shaped profile, andwherein the conical arch includes an edge near the seat, the edge defining an outer perimeter of the star-shaped profile and lying entirely within an inner circle and an outer circle, the ratio of the diameter of the inner circle to the diameter of the outer circle is greater than or equal to 0.7, the facets, grouped in pairs, defining branches of the star-shaped profile. 14. Container according to claim 13, wherein each of the facets is planar.
