The container has a body extending between a neck and a base (3) that has an annular zone (5) surrounding a bottom of a concave arch (4) and forming a plane seat. The base has clamp zones (11) separated from each other and extending a bottom of the body radially in a direction of a central axis of the base, where the clamp zones project offset outward relative to the arch. Radial grooves (12) are radially defined between the clamp zones and have a bottom (13) formed by radial sections (4a) of the arch. The grooves have a radially variable depth maximum in line with the annular zone.
