A container arrangement (10) (Fig. 5) comprising a support structure in the form of a frame assembly (12) and flexible containing means (14) attached to the assembly (12) generally at the open top end of the means (14) and arranged to define a space (16) to contain material therein, the assembly (12) being generally collapsible substantially as an integral unit from a first, erect condition (Figs. 1, 5) in which the containing means (14) defines a relatively large space (16) for containment of material, to a second, collapsed condition (Fig. 3) following or during dispensing of material, for transport and/or storage. A movable base plate (62) is pivotally connected along the side thereof adjacent a dispensing valve arrangement (58) about a torque bar (64). The torque bar (64) is in torsion when the base plate (62) lies above a fixed base (54), and is generally free from torsion, when the base plate (54) is inclined on the base plate (54) in a direction down toward the slot (56), such that as the weight of material in the container and bearing on the movable plate (62) reduces as material is dispensed through the valve arrangement (58), the plate (62) gradually inclines to slope down toward the valve arrangement (58) and thereby guide material to the valve arrangement (58) to be dispensed. |
