<p>A container (1) made from a plastic material, provided with a body and with a bottom (6) extending from a lower end of the body, the bottom (6) comprising: a peripheral seat (7) defining a positioning plane (8); - a concave arch (10) that extends from a central zone (11) to the seat (7); and a series of main reinforcement grooves (13) that extend radially from the central zone (11) at least to the seat (7). The arch (10) has two concentric regions, i.e. a central region (15) and a peripheral region (16), separated by a median axial step (17) that extends annularly in a continuous manner around the central zone (11), such that the central region (15) is raised relative to the peripheral region (16).</p> |
