- the body 5 comprises a succession of stiffeners 6 in the form of annular beads separated in pairs by annular grooves 7.
- some grooves 7a located near the shoulder 4 have a V-shaped profile to provide the 1 container of the radial stiffness while allowing axial retraction thereof in this region, while the following grooves 7b, in the central portion of the container 1 and in its lower part, have a flat bottom U-shaped profile to provide the container 1 a stiffness both axial and radial.
- the container 1 further comprises a bottom 8 which extends to a lower end of the container 1.
- the bottom 8 comprises an annular base 9, through which the container 1 can rest stably on a flat surface (such as a table ) and which extends substantially perpendicular to the body 5 (or to the axis X of the container) in the extension thereof.
- the bottom 8 also comprises an annular step 10, which extends from the base 9, in the extension thereof towards the inside of the container 1.
- the step 10 is preferably frustoconical; the angle at the top of this step is between 30 ° and 90 °.
- the bottom 8 further comprises an annular membrane 11, which extends in the extension of the step 10 towards the axis of the container 1, substantially perpendicular to the body 5 (or the X axis).
- the bottom 8 finally comprises, at its center and in the extension of the membrane 11, a central pin 12 which projects inwards towards the container 1.
- the membrane 11 has, at the junction with the step 10, a circular outer edge 13, and at the junction with the pin 12, a circular inner edge 14.
- the membrane 11 is, before hot filling of the container 1, concave concavity turned towards the inside thereof.
- the inner edge 14 of the membrane 11 appears to be situated below the outer edge 13 - without, however, that the inner edge 14 exceeds the plane of the base 9.

- the 1 container is considered in a vertical position, for example laid flat on a flat support such as a table, the inner edge 14 of the membrane 11 appears above the edge 13 outside.
- the membrane 11 is preferably in the form of a spherical cap, of symmetry of revolution about the main axis X of the container and whose radius of curvature is between 50 mm. and 150 mm.
- the expression "spherical cap” here refers to a curved surface, for which the radius of curvature is substantially continuous, that is to say that the concavity does not change on the surface.
- the radius of curvature of the membrane 11 is preferably between 60 and 80 mm, for example about 70 mm.
- the radius of curvature of the membrane 11 is preferably between 80 mm and 120 mm, for example about 100 mm.
- the pin 12 has a side wall 15 of generally conical shape, surmounted by a substantially plane circular outline top 16, at the center of which is a pellet 17 of amorphous material not stretched, corresponding to the injection point of the preform from which the container is made. According to an embodiment illustrated in FIG.

- the bottom 8 rises, from its intermediate configuration described above, to a final configuration where the membrane 11 bends in the opposite direction around its outer edge 13, the pin 12 going back to beyond its initial position (that is to say before any filling).
- the membrane 11 may, in the case of the first embodiment described above, see its inverted curvature with respect to its initial configuration, that is to say that its concavity is turned outwards. of the container 1, as shown in phantom in FIG.
- annular stiffeners 6 in the form of beads on the body 5 and a deformable membrane 11 in the bottom 8 causes the deformations to be located on the bottom 8, firstly during the hot filling, then during the subsequent cooling of the liquid.
- the crystallinity of the bottom 8 can be mechanically increased by a so-called boxing process within a mold provided with a sliding mold bottom parallel to the axis.
- X of the container 1. the mold bottom is first placed in a low position below its final position, which allows, in a first step, to stretch the bottom 8 of the container 1 beyond its final position. Then the mold bottom is reassembled to give the bottom 8 its final shape by stretching the material to the maximum.
- a description of a process of this type can be found in the document FR 2 508 004.
- a container 1 according to a third embodiment is now described, with reference to FIGS. 6 to 10.

- the step 10 is extended, in the direction of the axis of the container 1, by a bearing 20 which, at rest (that is to say in the absence of stress exerted on the container 1 - in practice prior to the filling) is frustoconical at a very open angle. More precisely, as illustrated in the right-hand part of FIG. 9, the angle ⁇ that forms a generatrix of the bearing 20 with a horizontal plane perpendicular to the axis of the container 1 is between 3 ° and 10 °, and preferably between 5 ° and 7 °. According to a preferred embodiment, this angle is about 6 °.

- the body 5 in order to confer a structural rigidity of the body 5 sufficient to transfer to the bottom 8 most of the deformations resulting from the stresses to which the container 1 is subjected during a hot filling, the body 5 has a thickness to that of ordinary containers, including containers usually referred to as heat resistant (Heat Resistant or HR). In practice, it will be ensured that the thickness of the body is greater than 4/10 mm, a thickness between 4/10 mm and 9/10 mm which can be considered satisfactory.
- HR Heat Resistant
- the body 5 substantially retains its original shape either in view of the presence of stiffeners or because of its thickness.
- the bottom 8 deforms initially by reversing the angle ⁇ of the bearing 20, conjointly with the deflection of the riser 21 and the diaphragm 11 , with a possible inversion of the concavity thereof, accompanied by a lowering of the pin 12 without however the base thereof 12 does not exceed the plane of the base 9 (see the corresponding configuration shown in phantom in the figure 9).
- the ribs 22 flatten out, their apex angle opening as the membrane 11 flexes (see the configuration shown in phantom in FIG. 9).
- the bottom 8 rises to a position greater than that of its initial position before the upturn due to hot filling, while the ribs 22 tend to close again by contributing locking the membrane 11 in its final position.
- the membrane 11 is always in the form of a spherical cap, but it is subdivided into two concentric parts 25, 26, namely: 25, surrounding the pin 12, and a peripheral portion 26, which extends around the central portion between it and the riser 21.
- the central and peripheral portions are themselves in the form of a spherical cap, their concavity being rotated in the same direction, so that the overall shape of the membrane 11 is more precisely a spherical cap comprising a fold formed by the rib 27.
- the rib 27, whose profile is in this case circular, has, on the side of the central part, a frustoconical inner flank 28 and, on the opposite side, on the side of the peripheral portion 26, a frustoconical outer flank 29.
- the angular aperture of the V-shaped section of the rib 27 is preferably between 90 ° and 130 °, and preferably between 100 ° and 120 °. According to a preferred embodiment illustrated in the figures, the angle at the apex of the section is about 10 °.
- the V-shaped profile of the central rib 27 is not symmetrical, the internal flank 28 having a smaller vertical extension than the outer flank 29.
- the central portion of the membrane 11 is located, in the normal vertical position of the container 1 and at rest, slightly higher than the peripheral portion 26.
- each rib 22 has a top view of a spear shape.
- the crest 24, which joins the flanks 23, extends from the base of the central rib 27 to the top of the riser 21, at its junction with the bearing 20.
- the bottom 8 initially deforms by joint bending of the bearing 20, the riser 21 and the peripheral portion 26 of the membrane 11, accompanied by a joint lowering of the central portion of the membrane and the pin 12.
- the central part 25 can adopt, in the vertical normal position of the container 1, a lower position than that of the part
- the radial ribs 22, six in number, are anchored inwardly at the junctions between the straight sections 30 and the curved sections 31 of the central rib 27.
- the bottom 8 deforms substantially in the same manner as previously described for the fourth embodiment.
- the inventors have observed a better rigidity of the bottom 8 in its final configuration (after cooling of the liquid), to which contributes the triangular shape of the central rib 27.
- the curvature of the curved sections 31 in plan view, see FIG. 17, which is comparatively lower than the curvature of the circular profile presented in the fourth embodiment, tends to increase the structural rigidity of the rib 27.
- the membrane January 1 is always in the form of a spherical cap on which are provided, projecting inwardly of the container 1, ribs 22, however, they have a different profile.
- each rib 22 comprises: two radial sections 32 with a lance-shaped profile, spaced apart from one another on the circumference of the membrane 11 and anchored to an outer end, in the riser 21, an arcuate intermediate section 33, which connects the radial sections 32 on the side of the pin 12, thus giving the rib a U-shaped profile in plan view (see Figure 21). It should be noted that this intermediate section 33 is thinner, in top view, than the radial sections 32.
- a main zone 34 in the form of a cross (in this case with four branches), delimited jointly by the ribs 22 and the riser 21 and carrying the pin 12, a plurality of localized peripheral zones, each delimited individually, internally by a groove 22 and externally by the riser 21, and thus having a top view (see Figure 21) a biconvex lens shape.
- the body 5 substantially retains its original shape either in view of the presence of stiffeners or because of its thickness.
- the membrane 11 is deformed under the combined effect of the hydrostatic pressure and the temperature of the filling liquid. Given its structure, as just described, the membrane 11 deforms non-isotropically. More specifically, the main zone 34, carrying the pin 12 and subjected to a high hydrostatic pressure, collapses simultaneously with flexing downwards (in the manner described for the third embodiment and shown in dot-dashed lines). Figure 9), the sections of the bearing 20 and the riser 21 in which is anchored the main zone 34. Once the deformation of the main zones 34 has been achieved, the peripheral zones pivot around the radial section of the ribs 22 to provide additional movement.
- the bottom 8 differs from the bottom 8 described in the sixth embodiment by the presence of a central rib 27 with a rounded triangular profile, as described in the fifth embodiment.
- the intermediate sections 33 of the ribs 22 are tangent to the straight sections 30 of the central rib 27.
- the membrane 11 is thus divided into two zones, namely: a central portion, surrounding the pin 12, and a peripheral portion 26, which extends around the central portion between the latter and the riser 21, this portion
- the device itself is subdivided into several zones of two types: peripheral zones delimited jointly by the ribs 22 and the riser 21, as in the sixth embodiment, and - peripheral peripheral zones 36 situated between the zones 35. and defined together by the ribs 22, the curved sections 31 of the central rib 27 and the radial sections 32 of the ribs 22.
- the central portion of the membrane 11 collapses below the peripheral portion 26.
- the rib 27 first facilitates the collapse of the central part during filling, then contributes, in reinforcing the ribs 22, the locking of the central portion 25 in its final position once the liquid has cooled.
- the final position of the bottom 8 is substantially the same as the initial position. Indeed, in the final position, the membrane 11 always forms a spherical cap, the concavity being substantially the same as the initial position.
- a bottom 8 according to any one of the embodiments which have just been described may be provided on a container 1 whose body 5 is rib as shown in FIG.
- a container 1 whose body 5 is substantially smooth, that is to say that it does not have ribs (27 to 29), but thickened, the ribbing or thickening of the body 5 having a structural stiffening function that avoids ovalization during a hot filling.
- a smooth body 5 with the bottom 8 as described according to one of the seven embodiments, the deformations generated by the hot filling of the walls of the container 1 are concentrated essentially on the bottom 8.
- This combination allows advantageously avoid the manufacture of a rib body. Indeed, for example, in the case of container manufacture by blowing a preform into a mold, the manufacture of a mold for a rib body is more expensive than that for a smooth body.
- a smooth body has a better aesthetic appearance than a rib body.
- the shape of the bottom 8, and more particularly the spherical shape of the membrane 11, allows better control of the deformation of the bottom 8, both during hot filling and during cooling.
