Abstract
The invention relates to a bottom of a mould for producing thermoplastic containers, and to a container thus produced. The container (1) produced comprises: a base (4) having a concave peripheral wall (6) extending essentially coaxially to the X-X′ axis, this concavity defining a non null curvature all along the wall (6); an annular region (7) forming a tubular peripheral wall (8) extending essentially coaxially to the X-X′ axis, the transversal radial distance between the X-X′ axis and said wall (8) being longer than the transversal radial distance between the X-X′ axis and any point along the concave peripheral wall (6) of said base (4); and a shoulder (9) forming a connecting region between the base (4) and the annular region (7). The depth of said annular region is between 0.5 and 2%, preferably between 1 and 1.5%, especially 1.2% of the diameter of the annular region (7), and the height of the base (4) is between 5 and 15 mm.
