Container made of plastic material comprising a body and a petaloid bottom that is connected to the body by a periphery , the bottom having a central axis ( X ) of symmetry and comprising: - a central dome that projects toward the interior of the container , delimited by a circular external edge at a distance R1 from the central axis ( X ); - a series of feet projecting toward the exterior of the container each of which radiates from the central dome and each of which has a peak radially remote from the central dome and a crest path that extends from the external edge of the central dome to the peak ; - a series of valleys each formed as a hollow between two successive feet , each valley radiating from an internal end to the periphery ; characterized in that : - each crest path has: • an internal section that extends from the external edge of the dome to a junction at a distance R2 from the central axis (X), said internal section having in a median radial plane of the foot a first curvature ( C1 ); • an external section that extends from the junction tangentially in line with the internal section to the peak , said external section having in the median radial plane of the foot a second curvature (C2) greater than the first curvature ( C1 ); - the position of the junction between the internal section and the external section is dependent on the size of the central dome such that the distances R1 and R2 are in a ratio such that: 45 % ≤ R 1 / R 2 ≤ 60% - a central dome that projects toward the interior of the container , delimited by a circular external edge at a distance R1 from the central axis ( X ); - a series of feet projecting toward the exterior of the container each of which radiates from the central dome and each of which has a peak radially remote from the central dome and a crest path that extends from the external edge of the central dome to the peak ; - a series of valleys each formed as a hollow between two successive feet , each valley radiating from an internal end to the periphery ; - each crest path has: • an internal section that extends from the external edge of the dome to a junction at a distance R2 from the central axis (X), said internal section having in a median radial plane of the foot a first curvature ( C1 ); • an external section that extends from the junction tangentially in line with the internal section to the peak , said external section having in the median radial plane of the foot a second curvature (C2) greater than the first curvature ( C1 ); • an internal section that extends from the external edge of the dome to a junction at a distance R2 from the central axis (X), said internal section having in a median radial plane of the foot a first curvature ( C1 ); • an external section that extends from the junction tangentially in line with the internal section to the peak , said external section having in the median radial plane of the foot a second curvature (C2) greater than the first curvature ( C1 ); - the position of the junction between the internal section and the external section is dependent on the size of the central dome such that the distances R1 and R2 are in a ratio such that: 45 % ≤ R 1 / R 2 ≤ 60% <EOS>
