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.

The invention claimed is: 1. A container made of a thermoplastic material and provided with a bottom of the "champagne bottom" type comprising a downwardly projecting central pimple, a peripheral bearing region and an intermediate arch provided with ribs radiating from the central pimple as far as the bearing region, wherein: said central pimple has a shape of a downwardly projecting circular plateau, said ribs are of dihedral shape with a V-shaped cross section, the mid-plane of which is substantially parallel to the axis of the container, and said ribs follow one another without discontinuity so as to define alternate valley bottoms and crests, and said dihedral-shaped ribs extend with a curved longitudinal profile from said central pimple as far as the bearing region but excluding said bearing region, with said valley bottoms having respective radially inner end regions adjacent to the central pimple which come up higher than a base of said central pimple and with said valley bottoms and crests having respective radially outer end regions adjacent to the bearing region which have respective curvatures blending gradually into a continuous rounded form of said bearing region, with no break in curvature in said respective radially outer end regions of said valley bottoms and crests immediately above said bearing region, so that said bearing region is substantially planar and continuous over its entire extent, whereby the rigidity of said bottom is increased while at the same time the thickness thereof is reduced, including in the bearing region. 2. The container as claimed in claim 1, said container being made of PET. 3. The container as claimed in claim 1, said container being a bottle the overall shape of which is approximately that of a cylinder of revolution and the bearing region is annular and substantially coaxial with the central pimple, the dihedral ribs extending radially. 4. The container as claimed in claim 3, said container comprising ribs each having the same angular breadth.
