Container with a petaloid base

A container (1) made of plastic material comprising a body (2) and a petaloid bottom (3) that is connected to the body (2) by a periphery (4) the bottom (3) having a central axis (X) of symmetry and comprising:

• a central dome (5) that projects toward the interior of the container (1), delimited by a circular external edge (7) at a distance R1 from the central axis (X);
• a series of feet (8) projecting toward the, exterior of the container (1) each of which radiates from the central dome (5) and each of which has a peek (9) radially remote from the central dome and a crest path (11) that extends from the external edge (7) of the central dome (5) to the peak (9);
• a series of valleys (15) each formed as a hollow between successive feet (8), each valley (15) radiating from an internal end (17) to the periphery (4);
• wherein:
• each crest path (11) has:
• an internal section (12) that extends from the external edge (7) of the dome (5) to a junction (14) at a distance R2 from the central axis (X), said internal section (12) having in a median radial plane of the foot (8) a first curvature (C1);
• an external section (13) that extends from the junction (14) tangentially in line with the internal section (12) to the peak (9), said external section (13) having in the median radial plane of the foot (8) a second curvature (C2) greater than the first curvature (C1);
• the distances R1 and R2 are in a ratio such that:
• 45%≤R1/R2≤60%.
