The invention concerns improvements to containers, in particular plastic bottles, having a body (2) with a circular non-cylindrical wall, so as to reinforce them and prevent cross-section variation when they are subjected to compression forces. Part at least of the wall is provided with a substantially planar relief. The wall is reinforced with peripheral grooves (26, 27, 28, 29, 30) oriented in planes substantially perpendicular to the longitudinal axis (X) of the container, and the part including a substantially planar relief is run through with several grooves. The width of each of the grooves is such that it is less wide (L2) where it emerges in the part of the wall than at the middle (L1) of its crossing. The invention is particularly useful for reinforcing large capacity bottles.

1. A container, which is made of plastic material, having a body (2) oriented along a longitudinal axis (X), with a non-cylindrical wall around this axis, the wall being reinforced by peripheral grooves (26, 27, 28, 29, 30) oriented along planes that are appreciably perpendicular to said longitudina
1. A container, which is made of plastic material, having a body (2) oriented along a longitudinal axis (X), with a non-cylindrical wall around this axis, the wall being reinforced by peripheral grooves (26, 27, 28, 29, 30) oriented along planes that are appreciably perpendicular to said longitudinal axis, at least one part (21, 22) of said wall having an appreciably flat relief and being traversed by several grooves, wherein a width of each groove traversing the part of wall having an appreciably flat relief is variable, the variation in the width (of each of said grooves being such that the width is less wide (L2) at an end in said wall part than in a middle (L1) of a crossover. 2. The container according to claim 1, wherein a bottom of a groove (29) traversing the part of wall having an appreciably flat relief (21, 22) has, at least along the crossover of that part, a curved profile with a concavity turned toward the outside of the wall. 3. The container according to claim 1, wherein the profile of the walls of each groove is composed of an alternation of curves or windings. 4. The container according to claim 1, wherein the body (2) has a cross section that is generally quadrilateral in shape, with rounded corners, so that the wall of the body is composed of the appreciably flat relief parts in the form of appreciably flat panels (21, 22), connected to each other by the rounded corners, and the peripheral grooves (26, 27, 28, 29, 30) have a variation in width in their crossover of a panel (21, 22), and the variation in width of each of the grooves is such that it is less wide at its ends in a panel than at the middle of its crossover. 5. The container according to claim 4, wherein a width (L3) of a groove in the middle of its crossover of a rounded corner part (23) is less than that (L2) at its ends in the panels. 6. The container according to claim 4, wherein a width (L3) of a groove in the middle of its crossover of a rounded corner part (23) is equal to that (L2) at its ends in the panels. 7. The container according to claim 1, wherein the container comprises a bottle.
