Container apparatus (2) for transporting and storing fluid material, comprising a flexible bag (8), a rigid frame member (10) which is attached to an upper portion of the flexible bag (8), a rigid base (12), and elongate support members (16) which are positioned outside the flexible bag (8) and which are movable from a first position in which they extend between the rigid frame member (10) and the rigid base (12), to a second position in which they allow the sides of the flexible bag (8) to collapse, and the container apparatus being characterised in that the rigid frame member (10) is provided with inboard portions (13) which are attached to the sides (9) of the flexible bag (8) thereby to draw the sides of the flexible bag substantially inboard of the rigid base and force the fluid material towards corners of the flexible bag which are formed by points of attachment of the flexible bag to corners of the rigid frame member and to create an upper portion to the flexible bag which has opposing sides which are inclined toward each other in order progressively to reduce the volume for a liner bag (6) to occupy as it is filled, and characterised in that the container apparatus is free of constraint members which extend parallel to the rigid base to constrain the sides of the flexible bag.
Cette invention concerne un contenant (2) pour le stockage et le transport de matériau fluide, qui comprend une vessie souple (8), un cadre supérieur rigide (10) fixé à la partie supérieure de la vessie (8), une base rigide (12) et des montants (16) disposés à l'extérieur de la vessie (8) et mobiles entre une première position verticale entre le cadre (10) et la base (12) et une seconde position repliée où ils permettent aux flancs de la vessie de s'affaisser. Le cadre rigide supérieur (10) est formé d'éléments cintrés vers l'intérieur (13) qui sont fixés aux flancs (9) de la vessie (8) de manière à tirer ceux-ci sensiblement vers l'intérieur, à forcer ainsi le contenu vers les coins de la vessie et à incliner la partie supérieure desdits flancs vers l'intérieur pour réduire au fur et à mesure du remplissage la place pouvant être occupée par une doublure (6). Le contenant se caractérise en outre par l'absence d'éléments de retenue transversaux parallèles à la base destinés à retenir les flancs de la vessie.
