A structure of reinforcing ribs disposed circumferentially around a container body portion of a container presenting a longitudinal axis, said structure comprising: - a pair of external ribs (61a, 61b) arranged around the bottle body, each external rib comprising a given pattern around the container body, said pattern being a series of at least two arcuate portions with a vertex interposed between the two arcuate portions; the pair of external ribs (61a, 61b) having an upper external rib and a lower external rib, said external ribs (61a, 61b) having their vertices facing each other and shifted circumferentially of a maximum distance of 5 mm and in which, - the upper external rib has a maximum amplitude between 3 and 6.5 mm and an arcuate portion length of half of the container perimeter; and - the lower external rib has a maximum amplitude between 2 and 5 mm and an arcuate portion length of half of the container perimeter. - A pair of intermediate ribs (62a, 62b) disposed between the pair of external ribs (61a, 61b), each intermediate rib comprising twice the same pattern around the container body, said pattern having an amplitude of about 2 to 6 mm and being in the form of two successive straight lines, one ascending straight line and one descending straight line forming a vertex at their junction; the pair of intermediate ribs (62a, 62b) having an upper intermediate rib and a lower intermediate rib, said intermediate ribs (62a, 62b) having their vertices facing each other and shifted circumferentially of a maximum distance of 6 mm and in which, - in the upper intermediate rib, the descending straight line is about 5 times smaller in length than the ascending straight line; and - in the lower intermediate rib, the descending straight line being about 5 times bigger in length than the ascending straight line - A central rib disposed between the pair of intermediate ribs (62a, 62b), said central rib comprising twice the same pattern around the container body; said pattern having an amplitude of about 2 to 6 mm and presenting an arcuate portion followed by an ascending straight line portion ending with a vertex, the arcuate portion being twice the length of the straight line portion. - a pair of external ribs (61a, 61b) arranged around the bottle body, each external rib comprising a given pattern around the container body, said pattern being a series of at least two arcuate portions with a vertex interposed between the two arcuate portions; the pair of external ribs (61a, 61b) having an upper external rib and a lower external rib, said external ribs (61a, 61b) having their vertices facing each other and shifted circumferentially of a maximum distance of 5 mm and in which, - the upper external rib has a maximum amplitude between 3 and 6.5 mm and an arcuate portion length of half of the container perimeter; and - the lower external rib has a maximum amplitude between 2 and 5 mm and an arcuate portion length of half of the container perimeter. - the upper external rib has a maximum amplitude between 3 and 6.5 mm and an arcuate portion length of half of the container perimeter; and - the lower external rib has a maximum amplitude between 2 and 5 mm and an arcuate portion length of half of the container perimeter. - A pair of intermediate ribs (62a, 62b) disposed between the pair of external ribs (61a, 61b), each intermediate rib comprising twice the same pattern around the container body, said pattern having an amplitude of about 2 to 6 mm and being in the form of two successive straight lines, one ascending straight line and one descending straight line forming a vertex at their junction; the pair of intermediate ribs (62a, 62b) having an upper intermediate rib and a lower intermediate rib, said intermediate ribs (62a, 62b) having their vertices facing each other and shifted circumferentially of a maximum distance of 6 mm and in which, - in the upper intermediate rib, the descending straight line is about 5 times smaller in length than the ascending straight line; and - in the lower intermediate rib, the descending straight line being about 5 times bigger in length than the ascending straight line - in the upper intermediate rib, the descending straight line is about 5 times smaller in length than the ascending straight line; and - in the lower intermediate rib, the descending straight line being about 5 times bigger in length than the ascending straight line - A central rib disposed between the pair of intermediate ribs (62a, 62b), said central rib comprising twice the same pattern around the container body; said pattern having an amplitude of about 2 to 6 mm and presenting an arcuate portion followed by an ascending straight line portion ending with a vertex, the arcuate portion being twice the length of the straight line portion.
