Container (1) made of a plastic material, provided with a base (7) including a standing ring (8) forming a support flange (9) and a diaphragm (11) extending from the standing ring (8) to a central portion (10), the diaphragm (11) being capable of standing in an outwardly-inclined position. The diaphragm (11) connects to the standing ring (8) at an outer junction (12) forming an outer articulation of the diaphragm (11). The diaphragm (11) connects to the central portion (10) at an inner junction (13) forming an inner articulation of the diaphragm (11). The diaphragm (11) is invertible with respect to the standing ring (8) from the outwardly-inclined position to an inwardly-inclined position. In the inwardly-inclined position, at least an inner portion (16) of the diaphragm (11) adjacent to the inner junction (13) is curved in radial section, with a concavity turned outwards.

1. Container (1) made of a plastic material, provided with a base (7) including a standing ring (8) forming a support flange (9) and a diaphragm (11) extending from the standing ring (8) to a central portion (10), said diaphragm (11) being capable of standing in an outwardly-inclined position, where
1. Container (1) made of a plastic material, provided with a base (7) including a standing ring (8) forming a support flange (9) and a diaphragm (11) extending from the standing ring (8) to a central portion (10), said diaphragm (11) being capable of standing in an outwardly-inclined position, wherein the diaphragm (11) connects to the standing ring (8) at an outer junction (12) forming an outer articulation of the diaphragm (11) with respect to the standing ring (8);wherein the diaphragm (11) connects to the central portion (10) at an inner junction (13) forming an inner articulation of the diaphragm (11) with respect to the central portion (10);whereby said diaphragm (11) is invertible with respect to the standing ring (8) from the outwardly-inclined position, in which the inner junction (13) extends below the outer junction (12), to an inwardly-inclined position in which the inner junction (13) extends above the outer junction (12);wherein, in the inwardly-inclined position, at least an inner portion (16) of the diaphragm (11) adjacent to the inner junction (13) is curved in radial section, with a concavity turned outwards with respect to the container (1); andwherein, in the outwardly-inclined position, the diaphragm (11) has an inner portion (19) curved with a concavity turned outwards with respect to the container (1) and having a radius (R3) of curvature, and an outer portion (20) curved with a concavity turned outwards with respect to the container (1) and having a radius (R4) of curvature smaller than the radius (R3) of curvature of the inner portion (19). 2. Container (1) according to claim 1, wherein, in the inwardly-inclined position, an outer portion (17) of the diaphragm (11) adjacent to the outer junction (12) is curved in radial section, with a concavity turned inwards with respect to the container (1). 3. Container (1) according to claim 2, wherein, in the outwardly-inclined position, the diaphragm (11) is curved in radial section, with a concavity turned outwards with respect to the container (1). 4. Container (1) according to claim 2, wherein the standing ring (8) is a high standing ring (8) provided with a frusto-conical inner wall (15) a top end of which forms the outer junction (12), whereby in the outwardly-inclined position the central portion (10) stands above the standing ring (8). 5. Container (1) according to claim 2, wherein the diaphragm (11) has an inner diameter (D1), measured on the inner junction (13), and an outer diameter (D2), measured on the outer junction (12), such that their ratio (D1/D2) is comprised between about 0.15 and about 0.45. 6. Container (1) according to claim 1, wherein, in the outwardly-inclined position, the diaphragm (11) is curved in radial section, with a concavity turned outwards with respect to the container (1). 7. Container (1) according to claim 6, wherein the diaphragm (11) has an outer diameter (D2), measured on the outer junction (12) and wherein, in the outwardly-inclined position, a radius (R) of curvature of the diaphragm is of about half the outer diameter (D2) of the diaphragm. 8. Container (1) according to claim 6, wherein the standing ring (8) is a high standing ring (8) provided with a frusto-conical inner wall (15) a top end of which forms the outer junction (12), whereby in the outwardly-inclined position the central portion (10) stands above the standing ring (8). 9. Container (1) according to claim 6, wherein the diaphragm (11) has an inner diameter (D1), measured on the inner junction (13), and an outer diameter (D2), measured on the outer junction (12), such that their ratio (D1/D2) is between about 0.15 and about 0.45. 10. Container (1) according to claim 1, wherein the standing ring (8) is a high standing ring (8) provided with a frusto-conical inner wall (15) a top end of which forms the outer junction (12), whereby in the outwardly-inclined position the central portion (10) stands above the standing ring (8). 11. Container (1) according to claim 10, wherein the diaphragm (11) has an inner diameter (D1), measured on the inner junction (13), and an outer diameter (D2), measured on the outer junction (12), such that their ratio (D1/D2) is between about 0.15 and about 0.45. 12. Container (1) according to claim 1, wherein the diaphragm (11) has an inner diameter (D1), measured on the inner junction (13), and an outer diameter (D2), measured on the outer junction (12), such that their ratio (D1/D2) is between about 0.15 and about 0.45. 13. Container (1) according to claim 12, wherein the inner diameter (D1) and the outer diameter (D2) of the diaphragm (11) are such that their ratio (D1/D2) is about 0.35. 14. Container (1) according to claim 1, wherein the respective radiuses (R3, R4) of curvature of the inner portion (19) and outer portion (20) of the diaphragm (11) are such that their ratio (R3/R4) is between about 0.2 and 0.4. 15. Container (1) according to claim 1, wherein the outer portion (20) of the diaphragm (11) connects to the standing ring (8) through an annular ring (22). 16.
