Plastic container comprising a body which extends along a main axis and a petaloid bottom extending the body, this bottom comprising: - a bottom wall with an overall shape which is convex towards the outside of the container, - a central dome which is in the form of a recess towards the inside of the container and extends from a central apex to a peripheral edge via which the dome is connected to the bottom wall, and - at least four feet which form protuberances from the bottom wall towards the outside of the container, separated in pairs by portions of the bottom wall forming at least four recessed valleys which extend radially from a central dome of the bottom to a periphery thereof, each foot having two flanks, each bordering a valley and a median face which, in a radial plane, has a curved profile with a concavity facing the outside of the container and is extended by an end face, the end faces jointly forming a standing ring which has a planar section and is interrupted in line with each valley; each valley has an internal portion (15, 15A, 15B) which extends from the central dome and an external portion which meets the periphery in the extension of the internal portion (15, 15A, 15B); the bottom comprises two groups of valleys arranged in alternation: o primary valleys, the internal portion of which is connected to the dome at the height of the peripheral edge thereof; o secondary valleys, the internal portion of which is connected to the dome between the peripheral edge and the central apex of the dome at a distance (F') from the peripheral edge, characterized in that the internal portion (15, 15A, 15B) and the external portion are, in section in a radial plane which is central in relation to the valley, straight and together form an obtuse angle salient towards the outside of the container and meet at an apex located in vertical alignment with or in direct proximity to vertical alignment with the standing ring. - a bottom wall with an overall shape which is convex towards the outside of the container, - a central dome which is in the form of a recess towards the inside of the container and extends from a central apex to a peripheral edge via which the dome is connected to the bottom wall, and - at least four feet which form protuberances from the bottom wall towards the outside of the container, separated in pairs by portions of the bottom wall forming at least four recessed valleys which extend radially from a central dome of the bottom to a periphery thereof, each foot having two flanks, each bordering a valley and a median face which, in a radial plane, has a curved profile with a concavity facing the outside of the container and is extended by an end face, the end faces jointly forming a standing ring which has a planar section and is interrupted in line with each valley; each valley has an internal portion (15, 15A, 15B) which extends from the central dome and an external portion which meets the periphery in the extension of the internal portion (15, 15A, 15B); the bottom comprises two groups of valleys arranged in alternation: o primary valleys, the internal portion of which is connected to the dome at the height of the peripheral edge thereof; o secondary valleys, the internal portion of which is connected to the dome between the peripheral edge and the central apex of the dome at a distance (F') from the peripheral edge, o primary valleys, the internal portion of which is connected to the dome at the height of the peripheral edge thereof; o secondary valleys, the internal portion of which is connected to the dome between the peripheral edge and the central apex of the dome at a distance (F') from the peripheral edge, characterized in that the internal portion (15, 15A, 15B) and the external portion are, in section in a radial plane which is central in relation to the valley, straight and together form an obtuse angle salient towards the outside of the container and meet at an apex located in vertical alignment with or in direct proximity to vertical alignment with the standing ring.
