Claim:
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.
