1. A container made of plastic material comprising a body and a petaloid bottom extending the body from a periphery, the bottom comprising a bottom wall that is generally convex, from which feet protrude that define a seat inscribed within a seating circle having a diameter whose ratio is less than 4:5 with respect to a diameter of the periphery, the feet being spaced apart by portions of the bottom wall forming hollow valleys that extend radially from a central zone of the bottom to the periphery, wherein each valley of the container comprises the following three adjacent components: a central section convex toward an exterior of the container and that extends from the central zone of the bottom, and which has, in a radial plane, a first radius of curvature;a junction zone concave toward the exterior of the container, located directly above the seating circle;a peripheral section convex toward the exterior of the container, which extends from the junction zone to the periphery, and which has, in said radial plane, a second radius of curvature, said peripheral section being offset toward the exterior of the container by an offset value with respect to the central section, the junction zone forming a step that defines two successive inflection points, a first inflection point at a change of concavity between the central section and the junction zone, and a second inflection point between the junction zone and the peripheral section;the offset value being equal to a distance between a first intersection point and a second intersection point, the first intersection point being located at an intersection of a reference axis and the central section or an extension of the central section, the second intersection point being located at an intersection of the reference axis and the peripheral section or an extension of the peripheral section, the reference axis being a straight line joining a center of curvature of a corresponding foot of the container and a center of curvature of the central section. 2. The container according claim 1, wherein the seat is formed by vertices of the feet that define punctuated ends. 3. The container according to claim 1, wherein the peripheral section has a radius of curvature that is greater than a radius of curvature of the central section so as to offset the peripheral section relative to the central section. 4. The container according to claim 1, wherein the radius of curvature of the peripheral section and the radius of curvature of the central section have a common center. 5. The container according to claim 1, wherein an extrapolation of a lower end of the curvature of the peripheral section extends below the curvature of the central section. 6. The container according to claim 1, wherein the ratio between the diameter of the seating circle and the diameter of the periphery is greater than 1:2. 7. The container according to claim 1, wherein each step defines two successive inflection points, all of the steps together defining a first inflection circle and a second inflection circle, the diameter of the first inflection circle being smaller than the diameter of the second inflection circle. 8. The container according to claim 7, wherein the ratio between the diameter of the first seating circle and the diameter of the second inflection circle is between 1.3 and 0.7. 9. The container according to claim 7, wherein the tangent to the first inflection point forms an angle (α) with the vertical that is smaller than an angle (β) formed by the tangent to the second inflection point with the vertical. 10. The container according to claim 1, wherein the bottom is provided with radial grooves extending along the valleys. 11. The container according to claim 1, wherein the offset value (E) and the value of the first radius of curvature (C) are such that their ratio E:C is between 1:100 and 1:25. 12. The container according to claim 11, wherein the ratio E:C is about 1:50. 13. The container according to claim 1, wherein the central section and the peripheral section have centers of curvature that do not merge. 14. The container according claim 1, wherein the central section and the peripheral section have different radii of curvature. 15. The container according to claim 1, wherein the offset value being in a range of 0.5 mm to 6 mm.
