BOTTLE MADE OF POLYMER MATERIAL

摘要

A bottle made of polymer material comprises a base (12) provided with a plurality of ribs (14). Each rib is composed of a curvature of the base (12) of the bottle which forms a protuberance in the longitudinal direction directed towards the inside of the bottle. The ribs extend in a radial direction along a line of radial extension (18). The bottle is characterized in that the projection, in a transverse plane, of the line of radial extension (18) of at least one of said ribs (14) is curved.
