Abstract
Disclosed is a container, made of plastic material, and provided with a base including a standing ring forming a support flange, an inner wall, a diaphragm and a central portion, the diaphragm being capable of standing in an outwardly-inclined position. The diaphragm connects to the standing ring at an outer junction, and connects to the central portion at an inner junction. The diaphragm is invertible with respect to the standing ring from the outwardly-inclined position to an inwardly-inclined position. In the outwardly-inclined position, the whole diaphragm is curved in radial section, with a concavity turned inwards with respect to the container. The diaphragm has a depth strictly greater than 1 mm.

Container (1) made of a plastic material, extending along a main axis (X) and provided with a base (7) including a standing ring (8) forming a support flange (11) and an inclined inner wall (10), said base (7) further including a diaphragm (13) extending from the inner wall (10) to a central portion (12), said diaphragm (13) being capable of standing in an outwardly-inclined position,
- wherein the diaphragm (13) connects to the inner wall (10) at an outer junction (14) forming an outer articulation of the diaphragm (13) with respect to the inner wall (10);
- wherein the diaphragm (13) connects to the central portion (12) at an inner junction (15) forming an inner articulation of the diaphragm (13) with respect to the central portion (12);
- whereby said diaphragm (13) is invertible with respect to the standing ring (8) from the outwardly-inclined position, in which the inner junction (15) extends below the outer junction (14), to an inwardly-inclined position, in which the inner junction (15) extends above the outer junction (14);
- wherein:
- in the outwardly-inclined position, the whole diaphragm (13) is curved in radial section, with a concavity turned inwards with respect to the container (1);
- the diaphragm (13) has a crest (17) and a depth (dp) measured, in radial section, between the crest (17) and a straight line joining the inner junction (15) to the outer junction (14), which is strictly greater than 1 mm.
