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.
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.
