A container made from thermoplastic material, of the type with a domed base, including a central projecting pimple, a peripheral support region and an intermediate arch, provided with ribs, extending from the central pimple to the support region but not therein, the ribs having a dihedral form with a straight section in a V in the medial plane, essentially parallel to the axis of the container and running into each other without a break. The ribs have a longitudinal profile which is curvilinear, the bases of the ribs, in the region thereof adjacent to the central pimple, extending higher than the base of said central pimple and the bases and crests of the ribs, in the region thereof adjacent to the support region, having curves merging progressively into a continuous rounding of unbroken curvature immediately above the support region such that the latter is essentially planar and continuous over the whole length thereof.
