Claim:
A container obtained by stretch-blow molding a preform of thermoplastic material, wherein the container is a bottle, comprising: a bottom; and a tubular body mounted to the bottom; the bottom including: a base having a central portion and a peripheral wall with a concavity oriented towards an interior of said container, said concave peripheral wall extending substantially coaxially to an axis X-X′ of said container, and said concavity defining a non-zero curvature at all points along said concave peripheral wall; an annular region disposed above said base, forming a tubular peripheral wall, the tubular peripheral wall being cylindrical or prismatic with multiple facets, said annular region extending from a lower portion of said tubular body; a radial distance between said axis X-X′ and said tubular peripheral wall being greater than the radial distance between said axis X-X′ and any point on said concave peripheral wall of said base; and a shoulder provided between the base and the annular region, forming a connecting region in a form of an acute angle intersection between said base and said annular region.
