1. A container (1) made of plastic material, provided with a body (11) and with a bottom (12) in a continuation of the body (11) at a lower end of the body (11), the bottom (12) having an oblong curved contour and comprising:
a seating surface (21) forming a standing plane (210) of the container, the standing plane having an oblong curved shape extending along a longitudinal median axis (ML) and a transverse median axis (MT), the seating surface (21) having a width (W), with a value w, between its distal ends along the transverse median axis (MT);
an arched area (22) extending from the seating surface (21) as far as a central zone (23) of the bottom (12), the arched area (22) delimiting a concavity from an outside of the container (1); the container (1) having a central axis (C) on which the central zone (23) is centered, wherein:
the seating surface (21) has width reductions that are situated on each side of the longitudinal median axis (ML), at least at an intersection between the seating surface (21) and the transverse median axis (MT),
the arched area (22) has, for each width reduction of the seating surface (21), for one part, an indentation (4) extending along an entire length of said width reduction of the seating surface (21) and forming a concavity from the outside of the container (1), and, for another part, a curved portion (220) extending directly from said indentation (4) in the direction of the central zone (23), and
wherein the arched area (22) has, between the central zone (23) and a width reduction of the seating surface (21), at least one bulge (3) extending longitudinally and forming, from the outside of the container (1), a concavity in the arched area (22).
