Abstract

L'invention concerne un contenant de transport (1) comprenant une enveloppe (2) qui est composée en particulier d'un tissu tubulaire et qui s'étend entre une partie inférieure (3) et une partie supérieure (4) de manière à former un volume de contenant destiné à recevoir des matières granulaires, fluides, visqueuses ou semi-fluides, en particulier du bitume. Le contenant de transport présente au moins une ouverture (5), ainsi que plusieurs, de préférence quatre, éléments de stabilisation qui s'étendent le long de l'enveloppe (2) de la zone de la partie inférieure (3) jusqu'à la zone de la partie supérieure (4) et dont les extrémités sont reliées au moins dans la zone de la partie inférieure (3) de manière à résister à la traction et à la pression par l'intermédiaire d'une structure de renfort, ainsi qu'un tampon (6) se trouvant dans le prolongement de l'ouverture (5) permet d'augmenter le volume du contenant de transport (1). L'invention concerne par ailleurs un procédé de remplissage de contenants de transport avec du bitume.
