1. Container of plastic material, comprising a body and a bottom, the bottom having an annular outer seat defining a principal seating plane for the container, and a deformable membrane that extends radially inside the annular outer seat and is arranged to be able to adopt two configurations: a retracted configuration, in which the membrane extends axially above the principal seating plane;a deployed configuration, in which the membrane comprises an annular inner seat in the form of an annular bead projecting towards the exterior of the container, which extends axially beneath the principal seating plane and defines a secondary seating plane, andthe bottom comprises a series of hollow reserves in the annular inner seat, the reserves extending radially astride the annular inner seat, which form local discontinuities of the secondary seating plane, the secondary seating plane being formed from a discrete series of sections of coplanar arcs at the end of the inner seat, which extend between the hollow reserves; and wherein the reserves have a central zone and connection fillets with adjacent sections of coplanar arcs, the central zone having a double curvature, a first curvature, viewed from the side, with concavity oriented downwards, a second curvature in radial cross section, with concavity oriented upwards. 2. The container according to claim 1, characterized in that the inner seat comprises an external section and a truncated cone-shaped internal section, joined at the inner seat, and in that the hollow reserves form a junction between the external section and the internal section through the inner seat. 3. The container according to claim 1, characterized in that each hollow reserve extends over an angular extension J such that: 3602n-10≤J≤3602nwhere n is the number of reserves on the bottom, and J is the angular extension of each reserve expressed in degrees. 4. The container according to claim 1, characterized in that each hollow reserve extends over an angular extension J substantially equal to an angular extension of a section of arc of the inner seat situated between two successive hollow reserves. 5. The container according to claim 1, characterized in that each hollow reserve extends radially over an extension greater than the width of the inner seat. 6. The container according to claim 1, characterized in that each hollow reserve extends radially over an extension of between one-seventh and one-third of the diameter of the inner seat. 7. The container according to claim 1, characterized in that each hollow reserve is in the shape of a horse saddle. 8. A container of plastic material, comprising: a body and a bottom;the bottom comprising an annular outer seat defining a principal seating plane for the container, and a deformable membrane extending radially inside the annular outer seat and structured to adopt a retracted configuration, in which the membrane extends axially above the principal seating plane; and a deployed configuration, in which the membrane comprises an annular inner seat in the form of an annular bead projecting towards the exterior of the container, which extends axially beneath the principal seating plane and defines a secondary seating plane;the bottom further comprises a series of hollow reserves in the annular inner seat, the reserves extending radially across the annular inner seat forming local discontinuities of the secondary seating plane such that the secondary seating plane is not continuous and defined by a discrete series of discontinuous coplanar arcs that extend between the hollow reserves; and wherein the reserves have a central zone and connection fillets with adjacent sections of the coplanar arcs, the central zone having a double curvature, a first curvature, viewed from the side, with concavity oriented downwards, a second curvature in radial cross section, with concavity oriented upwards.
